STUDIES IN THE THEACEAE, XV 
A REVIEW OF THE GENUS ADINANDRA 

Clarence E. Kobuski 

The genus Adhuindra was described by William Jack in Malay Misc. 
2(7): 50. 1822. At that time two Malaysian species. .!. dumosa and .1. 
sylvcstris, were described. Today the type-species, A. dumosa, has the 
widest distribution and is probably the best known of all the species in the 

Eighteen years later ( 1 S4U ) . V. Korthals added five new species to the 
genus and described at the same time Sarosanthcra, a new genus closely 
related to Adhuindra. This later genus was short-lived. It was reduced 
to a synonym of Adinandra and the single species, S. cxcdsa Korthals, was 
given the name. 1. Sarosanthcra by Miquel (Fl. Ind. Bat. 1(2): 477. 1859). 
who used the specific name Sarosanthcra since Korthals (1840) had 
described earlier a species named A. cxcdsa. 

The generic synonymy of Adinandra is very simple. The only described 
generic synonym is Sarosanthera, mentioned in the preceding paragraph. 
However, both Szyszylowicz ( I S93 ) and Melchior ( I "25) in their respec- 
tive treatments of the Theaceae in Nat. Pflanzenfam. listed Haenkaea 
Usteri, Ann. Bot. 6: 117. 179/1. as a synonym of Adinandra without any 
explanation. In Index Kewensis (vol. 1), under Adinandra Jack, is cited 
the synonym Haenkaea Usteri. This is merely a mechanical error which 
occurred in the compilation of the material for Index Kewensis. It is 
strange that the earlier date 1793 caused neither Szyszylowicz nor Melchior 
to investigate the generic status and the possible species described under 
Haenkaea. Haenkaea Usteri, in the alphabetical arrangement of Index 
Kewensis, is referred not to Adinandra Jack of the Theaceae, but to 
Adcnandra YYilld. of the Rutaceae, where it truly belongs. 

By 1868 nearly twenty species, all from the Malay Peninsula or Nether- 
lands East Indies, had been added to the genus by various authors. As a 
result the genus was considered to be localized to these areas. In 1868 
Oliver (Fl. Trop. Afr. 1: 170) described A. Mannii from the island of St. 
Thomas in the Bay of Guinea off the west coast of Africa. This species 



2 JOURNAL OF THE AILNOI.M MUiOUKTI M [vol. xxvm 

is quite different from the majority of species in the genus and several 
workers have suggested the possibility of generic segregation. A close 
study of the entire genus shows that the variations in .1. Mannii are not 
sufficient for generic limitation. 

In 1S74 Dyer described A. Griffithii from East Bengal and in 1878 
Clcycra MiUcttii Hook. & Arm, of China, was transferred to the genus. 
thus extending the range to its northern limits. In 1905 the genus was 
first recorded from the Philippines, when Merrill introduced .1. Iiizotiica. 
It received its southernmost range in 1025 when Baker described .1. 
Forbesii from New Guinea. 

From 1S22 until 1893 there had been no attempt on the part of any 
worker to treat all the species of the genus in a group. Frequently the 
genus was listed in local floras, but further than that little was offered as 
a composite study. 

In 1893 Szyszylowicz, in his treatment of the Theaceae for \';i1. 
Pllanzenfam.. although in very abbreviated form, listed the species of 
Adiuaitdra and offered a key for their identification. 

He introduced three new sections and separated them as follows: 

Sect. I. Fleutheraudra: Stamens free. 

Sect. II. Euadinandra: Stamens in bundles. 

Sect. III. Symphiandra: Stamens joined and disposed in a tube. 

It is difficult to understand, considering the material available at the 
time, how Szyszylowic/ could separate the species into Sections II and 
III. He lists . 1. Sarosanthcra Miquel in Sect. Ill and .1. lamponga Miquel 
and A. macrantha Teijsm. & Binn. in Sect. II. I consider all three con- 
specific. I have studied an isotype of A. Griffithii Dyer and know only 
on the word of the author that the stamens are uniseriate. He lists A. 
Miquclii King, a combination never made by King, under Sect. III. 
Adintuidra Miqudii is a synonym of Trrns/ronuia bancana Miq. 

Melchior (1925). in the second edition of the same publication, accepted 
the treatment of Szyszylowicz and added a fourth section as follows: 

Sect. T. Eleutherandra Szyszy.: Style entire. Filaments free. 

Sect. II. Euadinandra Szyszy.: Style entire. Filaments in bundles. 

Sect. III. Symphiandra Szyszy.: Style entire. Filaments joined and 
disposed in a tube. 

Sett. IV. Fleutherostyla Melch.: Styles free. 

As noted. Melchior added a second character, the entire style, which 
combined the fust three sections and separated them from his new section, 
I'JruthcrastyUi, which was created to include ,1. caloscricca Diels (1 ( >22). 
described three years earlier. In 1940 this new section was eliminated by 
the creation of a new genus. Archboldiodcndron, to which Adinandra 
calosrricca was transferred. The entire style cannot be attributed to all 
members of the other three sections created by Szyszylowicz because a few 
species are known to have styles that are three-, four-, or five-parted. 
Adinandra Griffithii Dyer (Bengal). .1. lasio[>ctala (Wight) Choisy (Cey- 



19171 KOBUSKI, STUDIES I.N TIIK THEACEAE, XV 3 

Ion). .1. filipcs Merrill and .1. nit/da Merrill (China), and A. Macgregorii 
Merrill (Philippine Isl.) are known to have parted styles, whereas in 
.1. qmnqm-partita Kobuski ( Borneo), in which the floral parts are described 
from a bud, the stigmas are distinctly five in number and the style, though 
apparently entire, is deeply five-sulcate. 

However, in his treatment Melchior states that the knowledge of the 
stamens is too incomplete to group the species by sections, especially in 
Sections II and III. and so he groups them in geographical regions, namely 
Ceylon, Indo-Malaya, East Asia, and Papua. This proved to be an 
excellent method of treatment. 

After a study of all the species described to date. 1 find that the majority 
of species, save perhaps .1. duniosa Jack and A. Millet ti! (Hook. & Arn.) 
Benth. & Hook., are of rather limited range. These two mentioned species, 
although of more extensive geographical distribution, remain in their 
respective areas. 

Although whenever possible the stamens are described in detail. I find it 
unfeasible to treat the species under the sections as outlined by S/.yszylowicz 
and Melchior. Kight out of every ten herbarium specimens, and this is a 
conservative estimate, have been collected in the fruiting stage, and. as a 
result, many spirits have been described from the fruit alone. Further- 
more, it is difficult, in working with herbarium material, to place a species 
definitely in its respective section even with the stamens present. 

In this study I have employed the same method of treatment as used by 
Melchior and feel that in this m 
easily. In preparing the keys, 
characters when possible.

Tm-i si'Kcihs: Adinandni dumosa Jack. 

An amplification of the foregoing formal description, with observations 
on the characters used in specific delimitation throughout the genus, 
follows: 

Leaves: Throughout the genus the leaves seldom furnish sound specific 
characters. Ordinarily the leaf is coriaceous. A very few species are 
known to possess chartaceous or subcoriaceous leaves. In size and shape 
one may find considerable variation on a single specimen. In most in- 
stances the leaves are obtuse, bluntly acuminate at the apex and tapering 
at the base. Occasionally there are consistent variations from this pattern, 
as found in the long-acuminate leaves of ,1 . acuminata korthals and .1. 
Bockiana Pritzel and its variety, the cordate leaf-base of A. cordifolia 
Ridley and its variety, and the subsessile leaf-base of .1. subscssilis Airy- 
Shaw. In these few instances specific delimitation may be based on the 

The terminal leaf-buds and very young unfolding leaves possess charac- 
teristics helpful in indicating the degree of pubescence on the leaves. In 
any group of plants with coriaceous and evergreen leaves there is apt to 
be a question concerning the interpretation of the degree of pubescence 
of the leaves. The mature leaves may have been glabrous in the juvenile 
stage or they may have been extremely pubescent, later becoming glabres- 
cent or even glabrous. In Adinandra, observation of the terminal leaf-bud 
offers an accurate means of determining the actual degree of pubescence 
or glabrosity of a given species. There are only a very few glabrous 
species, and in these cases only are the terminal leaf-buds strictly glabrous. 
The veining as a whole is not an outstanding character, nor is it con- 
sistent. The majority of species fall into a group where the veins vary 
from S to 15 pairs. Very often the veins are obscure and of little use in 
identification. Fxceptions may be found in .1. luzon'ua Merrill, where 
even the veins of lesser degrees are of the same prominence as the primary 
veins, and in .1. myr'wnvura Kob., A. polynvwa Lob., A. dasyantha 
Korthals, and .1. phlebophylla I lance, where the veins exceed more than 
twenty pairs in number, thereby presenting a conspicuous feature. The 
midrib is usually flattened or plane on the upper surface and semi-terete 
on the lower surface. In two species, A. verrucosa Stapf and .1. coUina 
Kob., the midrib on the lower surface is bisulcate. 



19471 KOBUSKI, S'l'l 1)1 KS IN THE THKACEAE, XV 5 

Pedicels: The pedicel length is 1-2.5 cm. for the majority of species. 
Unless the pedicel is less than 0.5 cm. or more than 3 cm. long it can hardly 
be used as a delimiting factor. The pedicel is seldom erect, usually being 
recurved. Pubescence on the pedicel plays the same role as pubescence 
elsewhere. 

Bracteoles: The persistence of the bracteoles is important. The 
greater number of species have persistent bracteoles, while in a smaller 
group of species the bracteoles are caducous. In the latter species the 
bracteoles may fall so early that their presence is recognized only by the 
scars, or the bracteoles may remain until anthesis before dropping away 
from the flower. Only in the persistent bracteoles and those remaining 
until anthesis can one find characters to be used for identification. Their 
position, shape and texture are of importance. In the majority of species, 
the bracteoles are opposite, at the apex of the pedicel, immediately below 
the calyx-lobes. When they are alternate, and alternate here means a 
variation up to 5 mm. in their positions, it is in the outer bracteole where 
the variation in position may be found. The inner bracteole arises imme- 
diately below the calyx-lobes, whereas the outer one is placed lower on the 
pedicel. In shape the bracteoles usually simulate the calyx-lobes. Often 
the two bracteoles vary considerably in size. 

Calyx: Always persistent, the calyx-lobes vary considerably from the 
period of anthesis to that of mature fruit. Hence size, unless very small 
or exceedingly large, is of lit lie importance. There is a marked variation 
in size in the lobes of a single calyx. The outer lobes are smaller, often 
more pubescent, and of heavier texture. In many species there is a grada- 
tion in size starting with the outer or smaller lobes and increasing in size 
to the largest or inner lobe. The margin of the inner lobes often is 
considerably more scarious than that of the outer lobes. The texture is 
of diagnostic importance. In the Eastern Asiatic spec ies and those of the 
Philippine Islands, the texture of the calyx-lobes is of a decidedly thinner 
quality than can be found in the other groups or more tropical regions 
where the lobes are definitely thicker, often subligneous. 

Corolla: The corolla remains as part of the flower for only a very 
short period. While still present it offers good characters in color, shape, 
length and pubescence. The lobes are always connate at the base; hence 
when dropping off the corolla falls in its entirety. White or cream is the 
color for the majority of species. Occasionally the corolla may be tinged 
with pink, and in British North Borneo and New Guinea a few species 
have purple lobes. In length the corolla may vary from a measurement 
equalling or slightly exceeding that of the calyx to three times the length 
of the calyx, as found in the two African species. ,1. Mannii Oliver and 
A. Schlie'benii Melchior. Pubescence is an excellent character in the 
corolla. The species can be divided almosl equally by this character. 
When present, the pubescence is usually of the appressed type and is 
concentrated on the median portion of the external surface. Occasionally 
one may find species where the pubescence extends over the complete 



6 .!<>( RWI, OF T1IK \ll\()! [) \i;i;ni;i II \1 |voi..xxviii 

external surface. Unlike that in Gtmionia, the pubescence is never found 

Stamens The stamens offer many excellent characteristics, when 
present, to aid in identification. However, being adnate to the base of 
the corolla, they usually fall away with the corolla. They are arranged 
in the flower in series which vary in number from one to five. When in 
series, one finds that the filaments vary in length according to the number of 
series. The filaments are rarely tree, but are connate for at least part of 
their length, usually that of the shortest filaments. Extreme difficulty is 
experienced working with dried material to determine the exact number of 
series. Stamens in a single series may averaue as low as fifteen in number 
(.1. Mumiii Oliver and .1. Sr/ilichrnii Melchior). while those in several series 
will number as high as 55-(>0. as found in .1. lirussii Kob. and .1. Forbcs'ri 
Bak. f. Variation in pubescence is considerable. In some species the 
filaments are glabrous, in others they are densely pubescent, and in still 
others one may find them pubescent on the upper portion adjacent to the 
anthers or on the dorsal surface only. The anthers are oblong, and with 
the exception of ,1. Maiuiii and .1. ScMicbcnii are always extrorse-hispid. 
In only the two above-mentioned species are the anthers glabrous. In 
some instances an elongated apicule may be of diagnostic importance. 

Pistil: Some of the best delimiting characters are found in the pistil. 
The style is persistent and either the ovary or fruit is present in every 
fertile specimen. The number of cells of the ovary has been little used 
even in descriptions. In immature flowers a cross-section is often difficult 
to obtain. In all spe< ies studied for this treatment the number of cells in 
the ovary and fruit are recorded. In a very few instances there is a 
variation within the species of number of cells in the ovary, and in such 
rare instances it is sometimes difficult to ascertain which is the usual 
number and which is the variation. The cells are for the most part quite 
clearly defined as to number. In several instances the placentae are of 
such length and consistency that they may be mistaken for cell-walls and 
as such they have obviously been interpreted in the past. Also, in a few 
species the cell-wall opposite the placentae may project so far into the cell 
that the branches of the placentae extend beyond the resulting indentation 
of the wall. A cursory study of such a dissection may very easily be 
misinterpreted. The fact that the ovary and the fruit are so filled with 
either ovules or seeds may very well lead to erroneous conclusions. Also, 
in rare instances the seeds may crowd the cells to such an extent that the 
walls are broken down and the seeds tend to displace the central axis or 
push into adjoining cells. However, these variations arc 1 exceptional. 

The number of cells in the ovary and fruit of the majority of species is 
five. In all species where the ovary is live-celled the- ovules are small and 
very many in number. The seeds, correspondingly, in the fruit are minute 
and usually number over a hundred. On the other hand, when the ovary 
and fruit are three-celled, the number of ovules and seeds is fewer and the 
seeds are larger than those in the five-celled species. The seeds here 



1947] KOBUSKI, STUDIES IN THE THEACEAE, XV 7 

measure up to 8 mm. long and seldom exceed ten in number for the entire 
fruit. Exceptions to this are rare but are found in A . javanica Choisy and 
A. lasiopetala (Wight) Choisy, where the fruit is three-celled but the seeds 
are minute and for all practical purposes countless. A few species have 
four-celled or two-celled ovaries. Of the two-celled group, A. subsessilis 
Airy-Shaw is interesting in that a single large seed is developed in each 
cell of the fruit. 

Pubescence of the ovary plays an important role in identification. 
When pubescent, the ovary is usually densely so. This pubescence may 
be evanescent and the resultant fruit may be glabrescent. However, in 
such instances one may always find a few stray evidences of pubescence 
at the apex of the fruit just below its juncture with the style. 

The style may be glabrous or pubescent. If the ovary is glabrous the 
style is also always glabrous. However, with a pubescent ovary one may 
find either a pubescent or glabrous style, depending upon the species. In 
any given species, however, the styles are usually consistent. In the 
majority of species the style is entire. However, in a few instances the 
style is divided into three or four parts, in accordance with the number of 
cells in the ovary. When the style is parted the number of stigmas is the 
same as the number of parts to the style. In a few species the style may 
be entire and the stigma lobed, in accordance with the number of cells in 
the ovary. In other species the style may be entire and the stigma 
distinctly five-parted. 

The following review of species has been divided into five geographical 
groups, namely: (1) Eastern Asia; (2) Indo-Malaysia; (3) Philippine 
Islands; (4) New Guinea; and (5) Africa. Material has been borrowed 
from most of the leading American herbaria where the genus Adinandra 
has been deposited in abundance. Added material on critical specimens 
was obtained later from the Royal Botanic Gardens at Kew. The author 
is deeply grateful to the curators of these institutions for the privilege of 
examining their material. In the citations of specimens throughout this 
paper these institutions are abbreviated as follows: 

(A) Arnold Arboretum of Harvard University. 

(C) Chicago Museum of Natural History.

EASTERN ASIATIC SPECIES 
In reviewing the species of Eastern Asia and comparing them with those 
of the other geographical regions, as arranged in this study, one is im- 
pressed by the close relationship of all the species of this area and the 
basic similarity of their characters. Specific differentiation is not as clear

cut in this area as in the Indo-Malavsian area. Many species have been 
described on the basis of rather feeble variations. The focal species is 
.1. Millettii (Hook. & Arn.) Benth. & Hook. Herbarium material has 
been rather plentiful for the Chinese .species, and further material may 
show that the number of species listed below, although conservative, is not 
conservative enough. 

The species described from Formosa and the Liu Kin islands are very 
closely related to .1. Millettii and its varieties. However, little could be 
done with these species, since the descriptions are often too meagre, and 
sufficient material for study lacking. 

Almost equally sparse have been herbarium specimens from Indo-China. 
During the course of this study, there appeared a belated (although pub- 
lished in 1942) study of the Theaceae of lndo-China bv (kignepain (Not. 
Syst. Mus. Hist. Nat. Paris 10: 112-131. 1942). In this paper seven new 
species have been described. Fortunately, types of four of Cagnepain's 
species were found in the material gathered tor this study and are treated 
in this section of the review. The remaining three, .1. annamensk, A. 
caudata, and ,1. donnairnsis, are quoted at the end of this section. The 
original descriptions and citations are inserted in this paper in order to 
make these records as complete as possible. Material is essential before 
an attempt be made to relate them to better known species. 

Immediately following is a chart of the characters used in separating the 
majority of the species of Adinandra. I'nder each element are listed the 
differences, and the species are recorded, whenever possible, under these 
differences. This chart has been helpful to me in the present study and 
it is hoped that it may be of assistance to other workers. Accompanying 
(harts will be found in the two following groups.

Adinandra Millcttii is the earliest described species of the genus from 
China. It has been most often collected, shows the widest distribution, 
and probably is the oldest Chinese species phylogenetically. In these 
respects it compares very favorably with the type. .1. dumosa Jack, from 
Indo-Malaya. 

The species itself is confined, according to the material available for this 
study, to the mainland of China; it ranges along the southeastern coast 
including the provinces of Chekiang. Kiangsi. Fukien and Kwangtung, and 
extends inland and westward to include Kwangsi and Anhwei. 

Two varieties are found in Formosa, A. Millcttii var. jormosana 
(Havata) Kob. (the erstwhile .1. jormosana Hayata) and ,1. Millcttii var. 
obtusissima Kob. Closely allied to ,1. Millcttii is the species A. Bockiana 
Pritzel and its two varieties A. Bockiana var. acutijolm ( Hand.-Mazz.) 
Kob. (,1. acuti folia Hand.-Mazz.) and A. Bockiana var. tonkinensis Kob. 
All these entities have many diagnostic characters in common, i. e. the small 



(lowers, the calyx-lobe- 



lilar in number, 



shape and arrangement, the filaments showing a definite and charac- 
teristic dilation toward the anthers, and the 3-celled ovary with a distinct 
spreading grayish pubescence which becomes glabrescent in the fruit. 



It Jul liWI, OF TIIK AHNOI.I) \KI!()IIKTl \| | v <»i.. wvni 

The corolla-lobes are similar in size, hardly extending beyond the 
calyx-lobes. 

The characters separating the two species are the shape of the calyx- 
lobes, the pubescence on the corolla-lobes, and the leaf-shape. These 
characters, none too strong, are consistent, however, in the two species. 
Whereas, in .1. Millrttii and its varieties the calyx-lobes are always long- 
acuminate with the attenuation starting near the base, in .1. Borkiana and 
its varieties the calyx-lobes are more rounded, occasionally abruptly 
apiculate but not long-tapering. In .1. Millrttii the corolla lobes are 
always glabrous on the external surface whereas in ,1. Bockiami the corolla- 
lobes are always pubescent on the median portion of the external surface. 
In the latter species the leaves art' larger and usually long-ai uncinate 

As might be expected, from the extensive range of the species, there is 
considerable variation in .!. Millrttii, especially in the leaves. One of the 
earliest collected specimens and perhaps the most cited (Sampson 1.55'IS, 
I'ak-wan. Kwangtung) shows, on the same sheet, branchlcts in which the 
leaves vary from obtuse to long-acuminate. This same variation can be 
found on several other specimens. Pubescence is another variable char- 
acter. Generally speaking, except for the current year's growth, .!. 
Millrttii may be considered quite glabrous, quickly losing its early 
pubescence. However, in some instances this glabrescence is less exten- 
sive, hence scattered hairs may be found on the undersurface of the leaves. 
the pedicels, and the calyx-lobes. 

In describing the stamens. Hooker and Arnott refer to the filaments as 
hairs and the anthers glabrous. The illustration accompanying the 
description portrays them thus. In the dissections made for this study, 
the filaments were always glabrous and the anthers pubescent. The 
reverse condition, as given by Hooker and Arnott. would be very unusual 
for this genus. 

A photograph and fragment of the type of . I. Drakrana Franchet, col- 
lected by A. David in Kwangsi in 1S73 and deposited in the Museum 
d'Histoire Xaturelle. Paris, show clearly that I. Drakrana is synonymous 
with .1. Millrttii. Probably Franchet was unaware of the existence of 
.1. Millrttii when he proposed he new species, because his suggested rela- 
tionships are with the Indo-Malaysian species .1. dumosa Jack and J. 
intrgcrrima T. Am lei son rather than with A. Millrttii. 

Another name, found on herbarium specimens but never adequately 
published, is .1. Ilrmslryi Handel- Mazzett i .Men all. evidently with some 
authority, stated thai Handel Ma/zetti had abandoned this name and never 
published the species because he felt the relationship was loo close to 
.1. Millrttii. Mrll 769 from Kwangtung is a representative of this

This variety differs from the species in several characteristics, none of 
them sufficiently consistent to warrant specific status. The leaves of the 
variety are usually distinctly serrate along the upper half of the margin. 
Generally speaking, the leaves of the species proper are quite entire. 
However, throughout all the material of the species examined one may 
occasionally find serration along the margin. The specimen of this variety 
most closely resembling typical . I. Millcttii from Formosa is Oldham 37. 
Here the margin of the leaves is more nearly entire with slight evidence of 
serration. The shape of the leaf is extremely varied. However, this same 
variation is found in the species. In Sasaki 21627 one may note, on a 
single branch, leaves which are obtuse, bluntly acuminate, or acuminate 
at the apex. 

The pedicels are generally longer, in rare instances attaining 3 cm. 
{Henry 514) in length. However. 2 cm. is the average length. Both the 
species and the variety have the same type of thin scattered pubescence 
on the ovary and fruit. Occasionally there is a slight evidence of pubes- 
cence at the very base of the style. This variation is not unusual in any 
species of Adinandra where there is a pubescent ovary and glabrous style. 
However, seldom is this variation found within the species. Hayata 
describes the stamens as ; 'x, saepius 15-17" in number. I found the 
number to be about 25, the same as in the species. 

Authentic specimens of I. hypochlora Hayata and A. pedunculata 
Hayata have not been examined. Kanehira, in his revised edition of 
Formosan Trees ( 1936), lists the two as synonyms of A. jormosana. The 
early descriptions, such as they are, seem to bear out this transfer by

deliberately with this in mind.

Added Description: Flowers axillary, solitary or rarely in twos; 
pedicel usually recurved, ca. 1 cm. long, lightly strigillose or glabrescent; 
bracteoles 2, quickly caducous, when present linear-oblong, ca. 2 mm. long 
and 1 mm. wide, slightly pubescent; calyx-lobes 5, imbricate, broadly 
ovate, subequal, 4-5 mm. long. 3-3.5 mm. wide, glabrescent or glabrous, 
the outer lobes somewhat acuminate, the inner lobes more rounded at the 
apex, the margin glandular and ciliate-fimbriate; corolla-lobes 5, connate 
at the base, ca. 7 mm. long, 4.5-5 mm. wide, rounded at the apex, pubescent 
on the median portion of the exterior surface; stamens ca. 25, uniseriate, 
ca. 5 mm. long, the filaments lightly adnate to the base of the corolla, free 
from each other, glabrous, ca. 2 mm. long, somewhat dilated in the middle,

Both Merrill and Gagnepain associated the specimens cited above with 
. 1. Mill rt tii. However, the acuminate leaves, the broadly ovate calyx-lobes 
and the pubescent corolla lobes show it to be a variation of .!. Bockiana 
and closely allied to .1. Bockiana var. acntijolia. The real difference lies 
in the pubescence. Whereas, in .1. Bockiana and ,1. Bockiana var. 
acutijolia the pubescence is spreading, in this variety the pubescence is 
short and closely appressed.

Flowers axillary, solitary; pedicel up to 3 cm. long, thickened at the apex, 
recurved, appressed-pilose; bracteoles 2, quickly caducous, alternate, when 
present oblong, acute at the apex, 5-6 mm. long, ca. 3 mm. wide, pilose; 
calyx-lobes 5, imbricate, thick, unequal, broadly ovate, outer lobes 11-13 
cm. long, 10-11 cm. wide, sericeous on the median portion of the dorsal 
surface, the inner lobes pubescent, smaller, less thick, the margins more 
scarious; corolla-lobes (fide Hu) "5, unequal, broadly ovate-oblong, to 
13 mm. long, 7 mm. broad, slightly grey-ferrugineous-sericeous outside, 
glabrous inside serrulate along the margins;" stamens 40-45, seemingly 
uniseriate, rather uniform in size, the filaments short, thickened, ca. 2 mm. 
long, glabrous, the anthers ca. 4 mm. long, densely sericeous on the dorsal 
surface, apiculate: ovary conical, densely sericeous, 5-celled, multi-ovulate, 
tapering at the apex into the short blunt style which is appressed-pubescent, 
the pubescence thinning out towards the glabrous apex. Mature fruit not 
seen, maturing fruit very thick-walled. 

There are several very obvious characteristics which aid in easily dis- 
tinguishing this species. First, the large, oblong-lanceolate leaves 20-24 
cm. long and definitely serrate; second, the large almost velvety calyx-lobes, 
similar in size and appearance to those of A. glischroloma var. macroscpala 
(Metcalf) Kob.; and third, the pubescence along the midrib of the upper 
surface of the leaf. 

Gagnepain described the same species under the name A. Petelotii. 
There is no need for discussion because the two arc obviously the same. 
Li's species, A. serrulata, was described from specimens with leaves some- 
what smaller (16-20 X 4-5 cm.), but otherwise matching those of A. 
megaphylla perfectly. 

Hu's original description is excellent and very detailed. He states, 
however, that the stamens are glabrous. Although only buds were available 
for dissection in this study, it is clear from these dissections that the stamens 
are very hirsute along the dorsal surface of the anther. Also Hu gives the 
impression from his description and later drawings in Icon. PI. Sin. that the 
bracteoles are persistent, whereas in the two specimens examined they are 
obviously quickly caducous. He fails to mention that the ovary and style 
are pubescent and that the ovary is five-celled. His later illustration, 
however, depicts pubescence on these parts.

Shrub or small tree; branchlets thick. Icicle, villous pubescent, the 
young branchlets and terminal buds covered with a brown, more 
dense villous pubescence. Leaves coriaceous, oblong-elliptic, S 14 cm. 
long, 3-5 cm. wide, acuminate at the apex, tapering at the base, usually 
cuneate, occasionally somewhal rounded, glabrous above, tawny-hirsute 
beneath, more densely concentrated along the margin and the midrib, the 
margin revolute, usually entire with occasional apiculate glands, the con- 
centrated pubescence (extending from beneath) appearing as a halo along 
the edge of the upper surface, the veins 10 12 pairs, conspicuous on both 
surfaces, the petiole S 10 nun. long, densely hirsute. Flowers axillary, in 
twos or threes, rarely solitary; pedicel d-l.S mm. long, erect or recurved, 
tawny-brown-hirtellous; bracteoles 2. caducous, opposite or alternate; 
calyx-lobes 5, imbricate, btoadh ovate, o 7 mm. long, hirtellous; corolla 
and stamens not seen; immature capsule 5 (died, hirtellous. the style ca. 
1 cm. long, the lower two-thirds hirtellous. the upper third glabrous. 

The tawny-hirtellous pubescence of the young branchlets. the under 
surface of the leaves and the flowering parts make this species and its 
varieties easily distinguishable. Concentrated along the margin, even when 
the leaf has become glabrescent. this pubescence projects beyond the edge 
of the lower surface in such quantity and to such an extent that when 
viewed from the upper surface it presents the appearance of a tawny halo. 
The species is unique in this character. Another unusual feature, for 
Chinese species, is the occurrence of the axillary flowers in twos and threes; 
only occasionally does one find solitary flowers. All material cited above 
is either in bud or in the post anthesis stage. Dissections of very young 
buds do show, even so. that the corolla-lobes are pubescent on the median 
portion of the external surface and are somewhat ovate in shape. The 
stamens, although they appear to be in series and over SO in number, are 
quite uniform in size. The filaments are glabrous and the anthers hirsute. 

In Tsang 213S7, the only specimen with developing fruit, the calyx-lobes 
measure close to 10 mm. in length and 5-6 mm. in width. 

Cited here as a synonym is the herbarium name . I. ch/iioisis Merrill. 
Metcalf (Lingnan Sci. Jour. 11:20. 1932) mentioned this unpublished 
species and listed it as a synonym of his own .1. macroscpala. Examina- 
tion of Merrill's specimens shows that Merrill had designated as the type 
of his unpublished species Wulsin's (Canton Christian College 12041) 
specimen and not I'/norj, .my/, which belongs to the variety macroscpala.

Hsien, on mountain slope, Y. L. Keng 312 (A), Auk. 5, 1926 (shrub 1-2 m.). 

The chief difference of this variety from the species is found in the size 
of the calyx-lobes. Whereas, in the species, in bud, the lobes measure 6-7 
mm. in length and in a single early fruiting specimen the calyx-lobes 
measure 9-10 mm. X 5-6 mm., in the variety, the calyx-lobes in bud 
measure 11-14 mm. in length. Their full development is not known. 

Dissections of flowers in bud, more nearly mature than those in the 
species, show that, like the species, their corolla-lobes are ovate, acute at 
the apex, and pubescent on the dorsal surface. The stamens, many in 
number, appear -to be seriate. The anthers are quite uniform and measure 
ca. 3 mm. in length. The filaments are very short and glabrous, while 
the apicule varies considerably in length, from 1-2-3 mm. 

One may assume that, when mature flowers of the species and variety 
are collected, all the floral parts of the variety will be uniformly larger 
than those of the species. 
4b. Adinandra glischroloma Handel-Mazzetti var. jubata (Li), comb. nov. 

Distribution: China (Kwangtung). 



This variety is characterized by a beautiful, dense, ferrugineous, 
iridescent tomentum (sometimes as much as 5 mm. long) on the terminal 
buds, young branchlets, under surface of the leaves, and flowering parts. 
Li separated it from A. glischroloma Handel-Mazzetti but it appears to 
be nearer the variety var. macrosepala and except for degree of pubescence 
is a perfect match for Chung 7369 collected in Fukien. 

In reality, except for pubescence, this variety seems to be midway 
between the species and the variety macrosepala. In the two latter entities 
the pubescence is very similar. However, they both agree with var. jubata 
in type of pubescence differing only in density.

This variety agrees with A. glischroloma Handel-Mazzetti in most 
characteristics. The flowers are axillary and like the species are in pairs, 
or in threes, rather than solitary. The buds are small and very hirsute. 
The pubescence of the leaves, although of the same type, is less dense. 
However, in the very young leaves, the pubescence appears more dense and 
typical of the species.

Shrub or small tree up to 10 m., rarely up to 25 m.; branches brown or 
grayish brown, terete, the very young branchlets and terminal buds 
appressed-pubescent. Leaves coriaceous, oblong-elliptic to oblong-obovate, 
6-8 X' 2-3 cm. and 10-13 X 5-6 cm., shortly acuminate at the apex, 
acute at the base, shining green above, paler beneath, glabrous on both 
surfaces, conspicuously dark-punctate beneath, the margin distinctly 
glandular-denticulate, the veins ca. 12 pairs, distinct on both surfaces, 
reticulate, the petiole ca. 5 mm. long, on larger leaves up to 10 mm. 
Flowers axillary, solitary; pedicel ca. 7 mm. long, strongly recurved, 
generally glabrous or glabrescent, those of the very young flowers 
appressed-pubescent especially at the very tip of the branchlets; bracteoles 
2, opposite, quickly caducous, when present pubescent, unequal, ca. 3 X 
1.5 mm. and 5X3 mm.; calyx-lobes 5, imbricate, densely tawny-seri- 
ceous-pubescent, subequal, 6-8 mm. long, ca. 6 mm. wide, ovate, sometimes 
subrotund at the apex, outer lobes thicker, glandular-denticulate along the 
scarious margin, the inner lobes thinner, the margin usually entire; corolla- 
lobes 5, connate at the base, white, pubescent on the median portion of 
the exterior surface, oblong-subelliptic, 7-8 mm. long, ca. 4 mm. wide, 
somewhat obtuse at the apex; stamens 30-35, seemingly uniseriate, rather 
uniform in size, 5.5-7 mm. long, the filaments 2-3 mm. long, glabrous, 
quite free from each other, adnate to the base of the corolla, projected at 
the apex into an apicule ca. 1 mm. long, the anthers ca. 3 mm. long, linear, 
pubescent; ovary minute, densely covered with whitish or tawny pubes- 
cence, 5-celled, multi-ovulate, tapering into a densely pubescent style 
6-7 mm. long. Fruit globose, black, pubescent, 5-celled, many-seeded, 
1-2 cm. diameter. 

The outstanding characteristics of this species are: (1) the 5-celled 
ovary; (2) the dense tawny pubescence on the floral parts; (3) the distinct 
reticulate veining obvious on both surfaces and the dark-punctate dots on 
the lower surface of the leaves; (4) the short, recurved pedicel; and (5) 
the glandular-denticulate margin of the leaves. 

Its closest relative is A. lasiostyla Hayata, which can be separated by 
the 3 -celled ovary, the obscure veining, the usually entire margin, and the 
scattered pubescence on the lower half of the style. 

Several synonyms are cited above, only one of which, A. rubropunctata 



24 .101 KWI. OF TIIK \K\OI.l) \KBORFTl \I Ivor, xxvm 

Merrill & Chun, needs comment. In 1940, Chun (Sunyatsenia 4: 188) 
listed seven specimens from Hainan as belonging to .1. rubropunctata. 
Of these, I have examined S. K. Lau 196, If. V. Liang 61760, F. C. How 
72471 and 73514. I can find no characters in these specimens that would 
warrant separation from the above species. Metcalf (1932) separates 
A. rubropunctata from .1. hainancnsis on the presence o\ red-punctate dots 
on the lower surface of the leaf, and the apiculate dent iculat ions along the 
margin. The original description stressed these two characters. Examin- 
ing considerable material, one finds great variation in the color of the 
punctate dots which range from black through brown to reddish brown, 
even to a lighter yellowish shade. This color variation is undoubtedly 
due to the age of the leaf. The apiculate dent iculat ions may he found on 
nearly even- leaf, varying in size and number. Age probably governs this 
characteristic also, as these apiculat ions are very fragile and are easily 
broken off. 

The type specimen of .!. rubropunctata, Tsiang 2713, offers the only 

cited above the pubescence is tawny or straw-colored, in the above-men- 
tioned type the pubescence is inure dense and ferrugineous. The pedicels 
of Tsiang 2713 are densely pubescent. As it happens, all the (lowers of 
Tsiang 2713 are concentrated at or near the apex of the young branchlets. 
so near as still to possess the pubescence found on the early growing parts. 
In the other specimens examined the flowers are scattered along the stems, 
and the pedicels are usually glabrous or onl\ slightb pubescent. In Tsiang 
2713, the bracteoles are consistently persistent. In the other specimens 
of .1. hainancnsis. the bracteoles are quickh caducous, but when present. 
are of the same size and shape as those found on the above-mentioned 
Tsiang specimen.

seemingly uniseriate, rather uniform in size. 5 5.5 mm. long, the filaments 
glabrous, 1.5-2 mm. long, quite free from each other but adnate to the 
base of the corolla, the anthers ca. 2.5 mm. long with dense tawny pubes-

slightly at the apex, scattered pubescent, 3-celled, mult i ovulate; style 
entire, up to 10 mm. long, 1-1.5 mm. in diameter near the base, sparingly 
pubescent along the lower half; stigma obtuse. Fruit immature. 

This species is closely related to ,1 . Millrttii (Hooker & Arnott) Benth. 
& Hook. f. and perhaps belongs to the same alliance of species. Certain 
consistently uniform characteristics, however, are present to warrant 
specific separation. The large pubescent acuminate leaves resemble those 
of . I. Bockiami Pritzel and its variety acutijolia (Hand.-Ma/z. ) Kob. 

A dense pubescence covers the young branchlets, lower leaf-surface, 
pedicels and calyx-lobes. Oddly enough, the style (whence the specific 
name) is only slightly pubescent with the scattered pubescence extending 
only along the lower half. 

The pedicel is very brief, not more than 5 mm. long, and always 
recurved. The calyx-lobes are rounded rather than acute and the exterior 
surface of the corolla-lobes is pubescent. 

Whereas A. Millcttii is considered a shrub and rarely a small tree, this 
species is definitely a tree of considerable magnitude according to Wilson, 
measuring "30-50 ft. X 2-5 ft." I presume the latter measure is cir- 
cumference. Wilson states that the species is very common at Arisan. 
All specimens examined by the author were collected from this locality or 
nearby Mt. Morrison. All other specimens cited in literature have been 
collected in the same general limited locality.

external surface except at the base where joined to the corolla, for the 
same distance joined to each other, the anthers lanceolate, nearly equal, 
1.5-2.0 mm. long, pubescent; the apicule short, 0.5 mm. or less; ovary 
somewhat conic-ovoid, densely gray-pubescent, 3-celled, tapering at the 
apex into an entire, pubescent style ca. 3-4 mm. long. Fruit small, ovoid, 
ca. 5 mm. long, 4 mm. diam., densely pubescent. 3-celled. few-seeded, seeds 
9-10, brown, scrobicular, ca. 2 mm. long. 

A few of the outstanding characteristics of this species are the small 
flowers and fruit, the persistent and comparatively large bracteoles. the 
very short pedicels, the pubescent filaments of the anthers, the entire 
leaves, and the small number of seeds developing in the fruit. 

Although not described until I "10. this species was mentioned in a list 
of the Hainan plants by Tanaka and Odashima in 1931, the name 
probably recorded from an herbarium sheet. 

Merrill and Chun, in their description, do not mention the number of 
cells in the ovary and fruit but in the accompanying illustration the ovary 
is pictured as six-celled. Because of the minute size and dense pubescence, 
dissections of the ovary are very difficult and quite unsatisfactory. On 
the other hand, the fruit, when mature, is so crowded with the few seeds 
which are normal in size, even though the fruit is small, that dissections 
again are rather unsatisfactory. After several dissections, none of which 
showed clear-cut cell-structure, my conclusions are that the fruit is three- 
celled rather than six-celled. It may be that in the original drawing the 
placentae, which often extend nearly across the cell, were mistaken for 
cell walls.

Adinandra laotka is in many respects a very close relative of A. angulata 
Ridley. Both species have thick branches and branchlets, terete in the 
former and decidedly angled in the latter. The leaves of both are stiff 
and heavy-coriaceous. The flowers are axillary and in pairs. In A. 
angulata the two pedicels remain attached at the base when removed from 
the stem and it appears that such may be the case in A. laotka. Both 
species are very glabrous, even to the terminal bud. 

In A. angulata, the ovary and fruit are ^-celled with few ovules and later 
with only a few large seeds developing, (iagnepain describes the ovary of 
A. laotka as 4-celled. My single dissection showed i he ovary to be clearly 
5-celled. Only buds were available to both ( Iagnepain and myself, and in 
the bud, the ovary is very Hat. thin and difficult to section. The bracteoles 
of A. laotka are caducous while in .1. angulata they are persistent. Also, 
the veins of the leaves of . I. angulata are less in number and much more 
prominent.

Adinandra ryukyuensis and .1. /ru-'I 'asiroi , the following species, must be 
linked together in this treatment. Both are from the Liu Kiu Island chain 
and may be identical. Translated descriptions are given here in an 
attempt to bring together as complete knowledge of the genus as possible. 
Although the description of the former is very incomplete, one cannot 
help but be impressed by the very close similarity between the two, even 
though varying terms have been used. Both have persistent bracteoles. 
In .1. ryukyuensis the size is lacking and in A. Zen-Tasiroi the shape is not 
recorded. The calyx-lobes are almosl identical in size, shape and pubes- 
cence. The fruit in both species is glabrous, a character which separates 
these two species from most others within their geographical range. In 
both species, the corolla and stamens are undescribed.

Yamamoto gave a detailed description. He states that the leaves are very 
obtuse or rounded at the apex, 4-7 cm. long, 2-3.5 cm. wide, pubescent on 
the under surface. Both by Yamamoto and Kanehira the leaves are 
illustrated as nearly rotund at the apex and rather broad. The calyx- 
lobes are subequal, ovate, 8 mm. long, 5 mm. wide, obtuse at the apex, and 
pubescent. The pedicel is listed as 2.5 cm. long. The fruit is described 
as globose, 3-celled, ca. 11-12 mm. in diameter, sericeous-pubescent with 
a persistent style 12 mm. long. Although not mentioned in the description, 
evidence of pubescence on the style is depicted in the illustrations. 

Only three specimens of this species have been cited in literature, all of 
them collected by Matuda. The localities of collection are in southern 
Formosa near South Cape. They are Ariko-banti, Ako, Matuda 25443 
and Mt. Daizyurin, Takao, Matuda 15544, 25545. 

I feel that this species is probably merely a variety of .1. Millcttii and 
may possibly be the same as .1. Millcttii var. obtusissima Kob., but since 
no opportunity has been available to compare the two entities, it is best to 
retain the specific status, even though dubious at the present time. 

Material for the following three species recently published by Gagnepain 
has not been available for this study. Except for the added citations of 
literature the descriptions are quoted as originally published.

DOUBTFUL SPECIES 



Although no material of the species has been available for this study, 
feel very dubious of its placement in the genus Adinandra. The descrip- 
an of the species leads one to believe that it belongs to the genus Cleyera. 



1947] KOBUSKI, STUDIES IN THE THEACEAE, XV 33 

Hu states in his description, "arbor ad 4 m. alta, omnino glabra; folia . . . 
margine integra leviter revolutaque . . . petioli robusti ... 1.5 cm. longi; 
. . . fructi 1-3, . . . sepala 5 ovata 5 mm. longa, marginibus ciliata; stylus 
tenuis 5 mm. longus; bacca globosa 8 mm. diametro; semina pauca, magna 
compressa ... 3 mm. longa, 2.5 mm. lata." 

The completely glabrous plant, the entire margin of the leaves, the 
petiole, robust and 1.5 cm. long, the margin of the sepals ciliate, the globose 
fruit 8 mm. in diameter and finally the few seeds are all features of 
Cleyera japonica Thunb. The only variations, in my opinion, are the 
sepals (5 mm. long) and the style (5 mm. long). In Cleyera the sepals 
are seldom longer than 3 mm. and rounded and the style is usually, not 
always, two- or three-parted. 

EXCLUDED SPECIES 
Adinandra bracteata Li in Jour. Arnold Arb. 26:65. lQ45 = Ternstroeniia : j insipnis 
Wu in Bot. Jahrb. 71: 195. 1940. 

Although no flowers or fruit remain on the specimen, Wang 39626, 
designated by Li as the type of A. bracteata, from the fragments of his 
dissection showing the many glabrous stamens arranged in series, the 
leaf-buds, and the sub- or pseudo-verticillate arrangement of leaves and 
branchlets, there seems little doubt that the species does not belong to the 
genus Adinandra, but probably to Terns troemia. 

There is a close relationship between Li's species and Tcrnstrocmia 
insignis Wu, collected at the same locality Lao Shan in Kwangsi. How- 
ever, from the descriptions there can be no certainty that they are identical. 
There is variation in leaf-size and stamen measurements. Li stated that 
the stamens of A. bracteata were "1.1-1.3 cm." long. The fragments of 
his dissections show stamens measuring 5-6 mm. in length, which compare 
favorably with those (5 mm. long) found in T. insignis. However, these 
stamens may have been taken from an unopened flower-bud, since the 
fdaments appear very short and undeveloped.

PHILIPPINE SPECIES 
Fifteen species have been described from the Philippine Islands under 
the genus Adinandra. The present study recognizes eight. Of these eight 
species six have been described by Merrill and one each by A. D. E. Elmer 
and C. B. Robinson. Three of the earlier described species have been 
transferred to other genera: A.coriacea Elmer to Ternstroemia gymnanthera 



34 JOIKWI. OF TUF. AKNOI.I) AKBORKTl M [vol. xxvm 

(W. & A.) Sprague, A. urdanetensis Elmer to T. urdanetcnsis (Elmer) 
Kobuski, and A. montaua Merrill to Clrycra japoutca Thunb. var. montana 
(Merrill) Kobuski. This last-named variety is the first representative of 
the genus Clvyrra in the Philippine Islands. 

The Philippine species of Adinandra form a distinct group among them- 
selves. Their relationships are more clearly with the Eastern Asiatic 
species than with the [ndo-Malaysian group. 

Below are listed the characters helpful in specific identification. Under 
these characters are recorded the species as far as present-day knowledge 
permits.

Tree up to 15 m. high, branching near the top; branches numerous, 
suberect, giving bushy appearance, the branchlets grayish brown, glabrous, 
striate, the very young branchlets, terminal bud, and very young leaves 
densely canescent. Leaves coriaceous, oblong-elliptic, 7 12 cm. long, 2.5-5 
cm. wide, acute, occasionally somewhat acuminate at the apex, cuneate at 
the base, usually glabrous on both surfaces, occasionally slightly pubescent 
with few scattered hairs along the midrib on the under surface, the margin

conspicuous beneath but not more prominent than the outstanding network 
of secondary and lesser veins, the petiole ca. 5 mm. long, usually glabrous 
or becoming so. Flowers solitary, axillary; pedicel appressed-pubescent 
at first, later becoming glabrous, 10-15 cm. long; bracteoles 2, opposite or 
slightly alternate, quickly caducous, when present unequal, triangular, 
3-3.5 mm. long, ca. 2.5 mm. wide at the base, pubescent; calyx-lobes 5, 
imbricate, unequal, broadly ovate, obtuse or subrotund at the apex, ca. 8 
mm. long. S 9 mm. wide, densely appressed-hoary-pubescent on the external 
surface, glabrous within, the outer lobes thicker with over-all pubescence, 
the inner lobes pubescent only at the center with the margins scarious and 
less pubescent; corolla-lobes 5, connate at the base, 10-12 mm. long. ca. 
9 mm. wide, appressed-hoary-pubescent on the median portion of the 
external surface; stamens 40 45, seriate. (> S mm. long, the filaments 
unequal, 3-4.5 mm. long, joined at the base and adnate to the base of the 
corolla, villous, the anthers nearly equal, ca. 3 mm. long, villous, tapering 
into a short apicule; ovary ovoid-conical, densely canescent, 5-celled, 
multi-ovulate, tapering at the apex into the style, the style glabrous except 
at the very base. 5-parted or tending to split into 5 parts. Fruit subconical- 
globose. ca. 1 cm. diam.. hoary-pubescent, 5 -celled, many-seeded; seeds 
brown, shining, ca. 1.5 mm. long. 

This species was the first of the genus described from the Philippines. 
One of the most outstanding characters is the reticulate appearance of the 
veins, especially on the lower surface. All veins, from the primary to the 
finer reticulations are of almost uniform prominence. The canescent 
pubescence of the calyx, corolla, ovary and that persisting through the 
fruiting stage on the calyx and fruit present another character excellent 
for distinguishing the species. 

Two specimens cited present considerable variation in leaf-size. Ramos 
c'r Edafio 2S736 collected in Tayabas I'rov. of Luzon has leaves over 15 
cm. long and, in some instances more than S cm. wide. The flowers are 
immature and appear smaller than those of the typical specimen. How- 
ever, the distinct veining and pubescence are the same. On the other hand, 
Ramos <*r Edafw 26630, from the same province, has leaves 8-15 cm. long 
and only 2-3 cm. wide. The calvx-lobes are smaller also. ca. 6 mm. long. 
However, like the specimen mentioned immediately above, in other respects, 
it agrees with the typical specimen.

Small tree; branchlets terete, brownish, glabrescent, the very young 
branchlets and terminal buds lernigineons-tomentose. Leaves submem- 
branaceous, oblong-elliptic, (3.5-) 6-10.5 cm. long, (1.5-) 2.5-3.5 cm. 
wide, acuminate at the apex, narrowed at the base, usually glabrous above, 
straggling to densely pubescent beneath, glabrescenl at maturity except 
along the midrib and margin, the margin glandular-serrate, sometimes 
ciliolate, the veins ca. 15 pairs, somewhat prominent beneath with all the 
orders of veins equally conspicuous, the petiole 2.5-6 mm. long, usually 
pubescent. Flowers axillary, solitary; pedicels up to 3.5 cm. long, slender, 
usually somewhat recurved, thinly pubescent; bracteoles 2, caducous, 
opposite and immediately below calyx; calyx-lobes 5, imbricate, broadly 
ovate, unequal, 6-7 mm. long. ca. 5" mm. wide; not as thick as in most 
species with less conspicuous variation at the margin, glandular-denticulate, 
the two outer lobes straggling-pubescent, the inner lobes quite glabrous; 
corolla-lobes 5, connate at the base, ovate, quite acute at the apex, densely 
pubescent in the middle of the exterior surface, ca. 10 mm. long;, 4-5 mm. 
wide; stamens ca. 30, appearing as a single series, the filaments glabrous, 
2-3 mm. long, adnate to the base of the corolla, joined inconspicuously, 
appearing almost free, the anthers 2-4 mm. long, densely pubescent, with 
an apicule ca. 1 mm. long: ovary subcorneal. 3-celled. densely pubescent, 
tapering at the apex into a glabrous style ca. 1 cm. long, the ovules many. 
Fruit ca. 1 cm. diam.. 3-celled, straggling-pubescent, multi-ovulate, the 
seeds minute, dark brown-black. 

The outstanding characters of this species are: (1) the submembrana- 
ceous elliptic leaves; (2) the generally long slender pedicels; (3) the 
3-celled ovary and fruit; (4) the 1 cm. long entire glabrous style; (5) the 
thin calyx-lobes; (6) the glabrous, nearly free filaments and pubescent 
anthers; (7) the seemingly always caducous bracteoles; and (8) the rather 
straggling pubescence. 

Adinandra Robinsonii Rimer is included here as a synonym. After 
studying the species. T can find no characters suitable for separating them. 
Elmer, in introducing A. Robinsonii, remarked that it was very close to 
A. elliptica and offered no basis for separation. Later. Merrill suggested 
that the relationship seemed too close for separation, although he continued 
to list them as distinct entities. 

Questionably cited here is Ramos & Edano 45597. The style is glabrous 
and entire, but the leaves are thicker, more coriaceous than most specimens 
of A. elliptica and the base is less acute. Williams 2533 from Mindanao

and Mcrritt SSJ-t from Mindoro have leaves large for the species. How- 
ever, in Williams 2533. the dissections of the ilowers showed no differences 
from typical .1. clliptica. My dissections of the ovary of the Williams 
number were unsatisfactory. Mcrritt SS34 is a fruiting specimen. Several 
dissections showed the fruit to be typically 3-celled. However, on the 
same specimen were fruits incompletely 3-celled appearing 5- or 6-celled. 

'ITie leaves of Elmer 101 S3, 101 S3 A from the island of Xegros are smaller 
and the pubescence generally more dense, but typical of the species. This 
latter character is true especially of the pedicel and calyx-lobes.

Tree 15 m.; brain hlets terete, graj ish, glabrous, the very young branch- 
lets invested with a dense, tawny, appressed-villous pubescence. Leaves 
coriaceous, elliptic to oblong-elliptic, 5-10 cm. long. 2-4 cm. wide, apex 
usually acuminate, acute to somewhat rounded at the base, the margins 
minutely but distinclb glandular-denticulate, the upper surface glabrous 
except occasionally near the very base, the lower surface with scattered, 
appressed tawny pubescence becoming glabrescent, the veins ca. 15 pairs, 
anastomosing, about equally conspicuous on both surfaces, the petiole 3-5 
mm. long, densely pubescent beneath, less so above. Mowers axillary, 
solitary; pedicels stout, recurved, up to 2.5 cm. long, measuring as much 
as ,5 mm. diam. near the calyx, pubescent; bracteoles 2. caducous; calyx- 
lobes 5, imbricate, unequal, up to 10 nun. long. ca. 7 nun. wide, ovate, 
acute at the apex, the outer lobes straggling-pubescent over the entire 
external surface, the inner lobes pubescent except along the margin, 
glandular-denticulate; corolla-lobes 5. unequal, connate al the base, obovate, 
up to 14 mm. long. 7-10 nun. wide, tawny-pubescent on the median portion 
of the external surface; stamens ca. 30. unequal in length, 8-10 mm. long, 
probably seriate, the filaments firmly adnate to the base of the corolla, 
glabrous, 3-5 mm. long, the anthers noticeably large, ca. 5 mm. long, 
usually equal or subequal, hirsute, prolonged at the apex into an apicule; 
ovary pubescent, 3- or 4-celled, tapering gradually at the apex into a broad 
gradually narrowed style (in type especially) which is split into 3 or 4 
parts at the apex, pubescent except near the tip, the 3 or 4 stigmas 
appearing oblique. Fruit not seen. 

From the material examined, this species seems to be localized in the 
Pauai area of Benguet Subprovince. All the material cited above, save 
two sheets from the adjoining Subprovince of Lepanto, are from Benguet. 
These Lepanto sheets are Merrill ■k)50 and Ramos & Edano 40276, 
collected at Mt. Data. 



1947] KOBUSKI, STUDIES IN THE THEACEAE, XV 39 

The ovary is generally three-celled and the style three-parted, three- 
ridged or entire. The type specimen seems to be the exception. Only 
two dissections were possible from the type and both showed a four-celled 
ovary. This was to be expected as the style, in both cases, was four-parted. 
On the same specimen were styles that were three-parted. In the type, 
the style is very thick at the base, and although tapering somewhat towards 
the apex remains quite bulky. In other cases, where the style is three- 
parted, the tapering is more finely drawn out. There is variation in the 
extent of pubescence of the style. It may be present on the lower half 
only or may extend up to the divided portion. Never is the style 
completely pubescent. 

The leaves are coriaceous, resembling in shape those of A. elliptica C. B. 
Robinson, the closest relative, the base, however, usually being more 
rounded. 

In A. elliptica, the floral parts are generally smaller. The calyx-lobes 
measure 6-7 mm. and the corolla-lobes 10 mm. in length. The style is 
glabrous and always entire. The leaves are membranaceous or submem- 
branaceous and taper at both ends. 

These two species are very difficult to separate, especially in the early 
stages of leaves and flower.

From the material examined, it appears thai this species is localized 
in the Mount Maquiling area in the Province of Lacuna on the Island of 

The bracteoles although caducous do not fall as <|uirkly as those in the 
majority of species. When present, they are unusual in character, being 
long-ohovate (6 X 3 mm.) and nearly equalling the calyx in length. The 
calyx-lobes themselves are characteristic, long and quite narrowly ovate, 
tapering to a distinct apicule. and covered with a straggling pubescence. 
The anthers are, as usual, hirsute with the pubescence extending down the 
filaments for a short distance which are glabrous for most of their length. 
The ovary is pilose 3 celled and multi ovulate, tapering into a style hirsute 
for almost its entire length, glabrous only at the very apex which is 
3-parted.

villous. Leaves coriaceous, oblong-elliptic, glabrous or glabrescent, 8 14

corolla, unequal. 7-1 1 mm. long, the filaments 4 S mm. long, joined nearly 
their entire length, hirsute on the external sulfate, the anthers ca. 3 mm. 
long, oblong, acute, hirsute; ovary glabrous, conical-ovoid, 3-celled. multi- 
ovulate. tapering at the apex into a glabrous, entire style ca. 6 mm. long. 
Fruit glabrous, globose, ca. 1.5 mm. diam., 3-celled; seeds ca. 25, dark, 
shining, scrobiculate, 5-6 mm. long. 

The nearly glabrous character of this species is one of its unusual 
features. The terminal buds and verv voung branchlets, the dorsal suit ace

of the corolla-lobes and the stamens appear to be the only exceptions. 
The anthers are always hirsute, even in the most glabrous species. Another 
feature of note is the persistent, opposite bracteoles. 

Merrill, in his original description of this species, records the ovary as 
5-celled. In all the material examined the ovary and fruit are consistently 
3-celled. Undoubtedly Merrill had poor material at his disposal when 
he devised this species, since the fruit is not described and the ovary is 
recorded as 5-celled. An isotype in the Kew herbarium which has been 
available for this study possesses both fruit and flowers. Had Merrill had 
such a specimen he would have seen the relationship between A. rostrata 
and A. Loheri at the time of publication, since they were published simul- 
taneously. Adinandra rostrata was published from the fruit alone. The 
type material of this latter entity shows the very large 3-celled fruit with 
large (5-6 mm. long) seeds which are few (10-20) in number. The 
pedicel is unusually long, measuring up to 4 cm. Adinatidra Loheri was 
described from flowering material in which the pedicels measured 2 cm. in 
length. Unfortunately the two specimens used as types of these two 
species represented the extremes in pedicel length, and since one was 
described from flowers and the other from the fruit they appeared to be 
different. Since then material has been collected which includes this 
variation in pedicel-length. In Loher 12^12, a flowering specimen, the 
pedicels vary from 2-3.5 cm. in length on the same specimen. 

Although several Philippine species are known to have 3-celled fruit, 
this is the only species in which the fruit has been described. It agrees 
with those Indo-Malayan species with 3-celled fruit in having fewer but 
larger seeds than the species in which the fruit is 5-celled.

ca. 13 mm. long. N.5- 10 mm. wide, rounded at the apex, tapering rapidly 
and thickened at the base, finely appressed-pubescent on the external 
surface except along the scarious margin; stamens ca. 40, unequal. 6-10

the entire length of the shortest filaments, densely hirsute except for ca. 
1 mm. at the base of the external sulfate where they are adnate to corolla, 
the anthers ca. 4 mm. long, approximately equal in length, hirsute, lanceo- 
late; ovary glabrous, conical ovoid, 3 celled, multi ovulate, tapering at the 
apex into an entire glabrous style ca. 7 mm. long. bruit not seen. 

The characters helpful in distinguishing this species are: (1) the 
unequal persistent bracleoles; (2) the roughened, thick, pubescent calyx- 
lobes; (3) the long stamens with the filaments joined their entire length 
forming a tube and sufficiently adnate to the base of the corolla (1 mm.) 
to fall off intact with the corolla; (4) the glabrous 3 iclled ovary; and (5) 
the glabrous entire style. 

The veining of the leaves of the species resembles very much that found 
in those of A. luzonicti Merrill. However, the apex of the leaf of the 
present species is rounded and the pubescence of the under surface less 
distinct. The midrib also is more roughened.

glabrous, ovoid, 5-celled. the ovules very numerous in each cell; style 
glabrous, 12 mm. long, the stigma minute, subcapitate. 

The only authentic material available tor this study is a sterile represent- 
ative of the type, deposited in the Tinted States National Herbarium. It 
has been necessary to rely, to a great extent, upon the original description 
by Merrill. 

Features of distinction appear to be: (1) the five-celled ovary: (2) 
the glabrous style, 12 mm. long; (3) the pubescent filaments, 4 mm. long;

(4) the large corolla-lobes, 18 mm. long, pubescent on the external sur- 
faces; and (5) the glabrous, subequal calyx-lobes, 7-10 mm. long, 7-8 

Very closely allied, and perhaps conspecific with it, is A. a porn sis Flmer 
from Mindanao. However, until more material is available for study, I 
prefer to retain them both as species. 

The five-celled ovary is found only in two other species, namely .1. 
luzoniea Merrill and A. apoensis. In the former species, the ovary, style, 
calyx-lobes, bracteoles and pedicel are covered with a dense, canescent 
pubescence which makes separation quite easy.

Tree ca. 15 m. high; branchlets terete, relatively short and numerous,

brous, elliptic-oblong. 5-9 cm. long, 2.5-4 cm. wide, broadly rounded or 
obtuse at the apex, occasionally slightly emarginate, cuneate at the base, 
the margin crenately serrate towards the apex, entire towards the base,

wide, pubescent on the median portion of the external surface; stamens 
ca. 35, unequal in length, 6-11 mm. long, probably seriate, the filaments 
2-7 mm. long, joined at the base only and adnate to the corolla, very 
hirsute, the anthers usually ca. 4 mm. long, occasional!} shorter, apiculate, 
equally hirsute; ovary glabrous, globose (not conical), 5-celled, multi- 
ovulate, the style terete, entire, glabrous. 1.5 cm. long, rising abruptly from 
the ovary, not tapering. Fruit not seen. 

This species appears very distinct from A. Icytensis Merrill, with which 
it formerly was considered synonymous. In A. apoensis, the style is easily 
1.5 cm. long, and rises abruptly from a globose, 5-celled glabrous ovary. 
In A. Icytensis the style is only 7 nun. long, approximately one-half as long 
as that found in A. apoensis, and it tapers gradual])* from a conical 3-celled 

The leaves in A. Icytensis have ca. 12 pairs of veins and the reticulations 
on the under surface are very distinct. Also the calyx-lobes are wider 
than long, very rounded at the apex and measure 5 X 6-6.5 mm. In 
.1. apoensis there are only ca. 7 or 8 pairs of veins and the reticulations,

although obvious, are less conspicuous. The calyx-lobes are broadly 
ovule, longer than broad, and measure S-° \ 7-8 mm. 

Cited here as a synonym is .1. Merrill ii Klmer. Having studied the types 
of both species, I can see no differences separating the two. Klmer men- 
tions in the original description of I. McrriUti that the ovary was "very 
lightly woolly." The material was very sparse, hence only a single ovary 
was studied. This appears to be glabrous and five-celled. Xo mention 
of the number of ovary-cells was made in the original description. Klmer 
also refers to the number of stamens as L 'S". This undoubtedly is a 
typographical error. An accurate count could not be made from the very 
poor specimen I examined. However, the number appears to be 30 or 

The closest relative appears to be .1. m^r a- punctata Merrill. So far, 
material of A. apoensis has been collected only from Mindanao. Adinandra 

nigra- punctata seems to have been collected only once, from the type 
locality in Luzon. Future collections may show additional distinguishing 
characters.

Small tree 4-10 m. high; branchlets terete, reddish hrown, glabrous even 
to the very young growth, including the terminal buds. Leaves coriaceous, 
glabrous, elliptic-ovate to elliptic-oblong, 5-8 (-10) cm. long, 2-3.5 (-4) 
cm. wide, usually more or less acuminate at the apex, sometimes blunt and 
shortly so, acute at the base, the margin entire, somewhat revolute in 
drying, the veins generally obscure, occasionally faintly visible on the upper 
surface, the petiole 5-10 mm. long, glabrous. Flowers axillary, up to 5 
in an axil, sometimes solitary; pedicel stout, usually 1-2 cm. long, occasion- 
ally slightly shorter, glabrous; bracteoles 2, opposite or alternate, quickly 
caducous, when present minute, quite scale-like, deltoid, ca. 1-1.5 mm. 
long; calyx-lobes 5, imbricate, glabrous, unequal ca. 3 mm. long, sometimes 
shorter, ca. 3 mm. wide, fimbriate-ciliolate along the margin, the outer lobes 
abruptly apiculate, the inner lobes more rounded; corolla-lobes 5, glabrous, 
obovate to narrowly obovate, 9-12 mm. long, 4-5 mm. wide; stamens ca. 
25, unequal in length, 4-7 mm. long, the filaments glabrous, adnate to the 
base of the corolla, sometimes appearing free, the anthers ca. 1 mm. long, 
very slightly retrorse-pilose; ovary glabrous, 3-celled, tapering into a 
glabrous style which is usually 3-parted, sometimes slightly so, occasionally 
incompletely so, topped by three stigmas. Fruit ovoid to globose, glabrous, 
three-celled, sometimes incompletely so, ca. 1 cm. diam.; the seeds minute, 
brown, varying in number. 

This is the first record of the genus Cleyera from the Philippine Islands. 
Described originally under Adinandra, this new variety of Cleyera japonica 
Thunb. has been collected profusely in many provinces of Luzon and 
Mindanao. 

The axial placentation of the ovary, the retrorse pubescence of the 
anthers, the entire leaves and glabrous terminal buds, the 3-parted style 
and 3-celled ovary, and the very small, subrotund, conspicuously ciliolate 
calyx-lobes are characteristics of Cleyera rather than Adinandra. 

There is considerable variation in the parts of the flower but none appear 
consistent enough for specific delimitation. Ordinarily the calyx-lobes are 
approximately 3 mm. long and about as wide. In Curran & Merritt 7846 
and Canicosa 30017 from Tayabas, Loher 12346 from Benguet and Cani- 
cosa 28980 from Laguna Province in Luzon the calyx-lobes are smaller, 
measuring only 2 mm. in length and width. However, in Mearns 4420 
and Ramos & Edano 44906 from Mt. Pulog, Benguet Province, the calyx- 
lobes measure 2.7 mm. and 3.5-4 mm. respectively. 

There is also variation in the pedicel-length and the size of the leaf. 
Ordinarily, the pedicel measures 1.5-2 cm. long. In the first two specimens 
mentioned above, namely Curran & Merritt 7846 and Canicosa 30017, the 
pedicel measures only 7 mm. These two specimens are generally smaller 
in most characters. In Ramos & Edano 40314 from Mt. Baudan, Benguet 
Prov., the calyx-lobes are 2 mm. long but the pedicel measures 2 cm. 
Ramos & Edano 44906 from Mt. Pulog has pedicels measuring 2 cm. in

British North Borneo. Including the thirteen new species proposed here, 
there have been fifty-two species describe. I under Adinnndra which fall in 
this geographical group. Of these, twenty four are recognized below, two

three are listed as little known. 

It is with regret that I list species as "doubtful'' or "little known." 
Material of these species tan surely be found in the herbaria of Malaya

under the strict shipping conditions in the Pacific area, the material is not 
available for this study. As a result of the war some of the material may 
never be available. 

Because of the lack of this material, my interpretations of some of the 
species of this group may be open to question. In too many instances it 
has been necessary to draw conclusions from a single specimen, often 
incomplete at that. In other cases decisions have been reached and the 
original descriptions only recorded when no material has been available at 
all. This information has been gathered, often very laboriously, from 
literature which appears annoyingly incomplete according to our present 
standards and which could apply easily to almost any species previously 
described. However precarious as it may be, I have attempted to bring 



1947 J KOBUSKI, STUDIES IN THE THEACEAE, XV 47 

together the species of this geographical group which are presented below. 

In this geographical area is found the true center of distribution of the 
genus. Species are much more varied in form than those of the Philippine 
Islands and Eastern Asia. Also, the number of species is considerably 
greater. 

As in the two former groups, I am recording a chart, compiled during this 
study, which brings together the characters most used in identification, and 
under these headings have listed the respective species.

Tree 15-20 m. with slightly angled branchlets, the branchlets glabrous

ceous, oblong-elliptic to oblong-oblanceolate. 12 15 cm. long, 4-5 cm. wide, 
acuminate at the apex, tapering at the base, glabrous on both surfaces, even 
in the very young leaves, the margin quite entire, the veins rather incon-

5-fid, the divisions of the style cylindrical, hardly ev ceding the calyx-lobes. 
Fruit not seen. 

The above description of this species is not as complete as one might 
desire. Although an isotype of the species has been available for this 
study, little additional information can be given at present. 

The outstanding feature of the species is the deeply five-parted style. 
In the majority of species of Adinaiidni the style is entire for the whole 
length. The only other known exception is . I . lasiopvtala (Wight) (noisy 
in which the style is three-parted. In .1. imprcssa Kob. and .1. quinquc- 
partita Kob. dissections made from buds show the style to be five-sulcate. 

The ovary of .1. Critfi/I/ii is undoubtedly live-celled, although not men- 
tioned as such by Dyer. Also one may assume that the corolla-lobes are 
glabrous on the external surface, because, were they pubescent, Dyer 
would have drawn attention to the fact, since he does describe the corolla. 
Dyer states that the bracteoles are vestigial. Observing them, I cannot 
be certain whether the\ are vestigial or caducous. I am inclined toward 
the latter. 

A specimen deposited in the U. S. National Herbarium at Washington 
may be mentioned here. This specimen, collected by Dr. Kind's Collector, 
no. 114, is incomplete. However, in an accompanying packet is material 
from previous dissections of buds showing the style definitely five-parted. 
The leaves are glabrous, as in the terminal bud. and the branchlets are 
slightly angled. The leaves are larger and less coriaceous than those of 
the type, measuring up to 20 cm. in length and 6.5 cm. in width. 

This additional specimen collected in the "Akha Hills" is recorded from 



1947] KOBUSKI, STUDIES IN THE THEACEAE, XV 53 

Duffla Hill as a "tree 50 to 60 ft. high, 3 to 4 ft. in dt.; leaves green, flowers 
white." It was collected in Feb. 1890. The actual collector's name is not 
clear but appears to be "Khan." This locality, Akla Hills, or Aka Hills, 
as it is recorded in some gazetteers, is on the northeastern frontier of India, 
northeast of the Darrang District of Eastern Bengal. Duffla Hill is also 
recorded as Daffla Hill. Aka and Daffla are names of independent tribes. 
This locality agrees very well with that of the type, Griffith 755, which was 
collected in East Bengal.

210O-2700 m, J. & M. S. Clemens 50781 (type, A), Dec. 6, 1933 (small tree; flowers 
white, the stigma 5-parted). 

Unfortunately, complete material was unavailable for the study of this 
new species. In fact the material is so incomplete that, were it not for the 
unusually distinctive character of the pistil, I would have refrained from 
describing it as new. 

The ovary is 5-celled, glabrous, and after swelling at the base tapers 
conically into an ill-defined style similar to those found in species of 
Gordonia. The style in the bud, which I examined, was undivided. 
However, the collectors, /. & M. S. Clemens, draw attention to the five 
divisions of the stigma and it is possible that, like A. Griffithii of India and 
A. lasiopetala of Ceylon the style fn open flower and fruit may be divided. 
The stamens, although no accurate count could be obtained, were typically 
those of Adinandra in number and character. The anthers were oblong, 
elongated, and bore the characteristic pubescence of the genus. The 
filaments also were lightly pubescent, in series, and joined for part of their 
length. The corolla-lobes, very tightly folded in the bud, could not be 
separated. However, they were glabrous and of a more thickened nature 
than those found in Gordonia. The ovules were attached to a slight 
placenta.

Like .1. quinquepartita Kob. this species has distinctly five stigmas. 
The style near the apex is sulcate with five distinct ridges. Dissections 
were made from the bud. It is possible that in maturing the style may 
become five-parted. The corolla is dark purple in color, and in the bud it 
is very elongate-conical, extending considerably beyond the calyx. The 
stamens, except for a rare evidence of pubescence on the anthers, are 
glabrous throughout. The leaves are thick-coriaceous with impressed 
nerves on the upper surface. The terminal buds are generally glabrous. 
However, there are rare instances of pubescence on the buds and very 
young branchlets. In glabrosity this species rivals I. dumosa Jack. The 
mature seeds are minute, measuring a single millimeter or less in diameter, 
and are red in color rather than the traditional dark brown.

Small tree ca. 10 m. high; branchlets terete, grayish brown, glabrous 
except when very young. Leaves coriaceous, oblanceolate, glabrous except 
when very young," 7-9 cm. long, 2-3 cm. wide, the margin serrulate, con- 
spicuously recurved especially along the lower half of the leaf, the petiole 
semi-terete, flat on the upper surface, ca. 5 mm. long. Flowers axillary, 
solitarv; pedicels somewhat recurved, ca. 1.5 cm. long, appressed-pubescent, 
thickened towards the apex; bracteoles 2, unequal, opposite, immediately 
beneath the calyx, persistent, somewhat rotund, 3-5 mm. long, finely 
appressed-pubescent; calyx-lobes 5, imbricate, thickened, unequal, some- 
what rotund, ca. 8 mm. long, the outer lobes finely appressed-pubescent, 
the inner lobes sericeous on the central portion of the outer surface, the 
margin glabrous, membranaceous; corolla-lobes 5, white, obtuse, ca. 2 cm. 
long, covered on the back with dense sericeous pubescence; stamens (fide 
Trimen et al.) monadelphous, 18-25, filaments unequal, sparsely hairy, 
joined at the base, the anthers sparsely pubescent; ovary 3-celled, glabrous, 
attenuate at the apex into a filiform, glabrous style which, on the maturing 
of the fruit, becomes 3-parted, the stigma 3-parted. Fruit globose, 3-celled, 
fide auct., many-, small-seeded; seeds hippocrepiform. 

This species is exceptional in the genus in having a 3-parted style (in 
the maturing fruit), and small seeds. These characteristics are similar to 
those found in Cleycra. The persistent bracteoles, the single, axillary 
flowers and the pubescent filaments separate it, on the other hand, from 
Cleycra. 

The only specimen available for this study is Thwaitcs (C. P. 775), quite 
an authentic specimen since it was used by Thwaites in his treatment. It 
agrees perfectly, as far as the available characters are concerned, with the 
illustrations of Trimen. The stamens were not seen by the present author, 
but the statement by Dyer that they are unequal leads one to believe that 
some form of seriate arrangement exists. Only in a single series are the 
stamens usually of equal length.

Adinandra dumosa, described by Jack in 1X22. is the original species of 
the genus and possesses the widest range of distribution of any of the 
Indo-Malayan species. It holds the same position in the Indo-Malayan 
distribution that ,1. Mitlcttii holds in the [•'.astern Asiatic distribution. The 
center of distribution for the species appears to be the island of Sumatra, 
the range extending northward into Malaya and down through the East 
Indian Islands into Java and Borneo. 

It is probably the most nearly glabrous species in the genus. Even the 
terminal buds and current year's growth of the branchlets are glabrous. 
Species of Adinandra are often termed glabrous when close observation 
shows that the terminal buds and current year's growth of branchlets are 
quite pubescent. As is usual in species of this family, one will find 
exceptions to the general rule. Specimens collected on the east coast of 
Sumatra near Bilah have a tendency toward pubescence. A fine scattered 
spreading pubescence, not too noticeable but enough to be exceptional, 
may be found along the midrib on the under surface of the leaves. How- 
ever, the unfolding buds are still quite glabrous since the dorsal surface of 
the leaf is exposed while unfolding. In the pubescent bud the obvious 
pubescence is on the dorsal surface of the leaf, which character is quickly 
dissipated and entirely lost in maturity. 

The leaves vary considerably in size and shape. Generally they are 
bluntly acuminate. Occasionally one finds leaves tapering into a fine 
acumen. The stamens are numerous with both the anthers and filaments 
densely pubescent. In the latter case, the pubescence is so dense that it 



58 JOURNAL OF TIIK ARNOLD ARBORETUM [vol. xxvm 

is difficult to separate the filaments in dissection. This dense pubescence 
on the filaments in so glabrous a species is surprising. The style develops 
considerably in fruit, rivaling, at times, the pedicel in length. The 
bracteoles, always persistent, are small, rounded and spreading. Occasion- 
ally, in the very young flower-buds, the bracteoles are lightly appressed- 
pubescent. 

In this study, I have had opportunity to examine authentic material, 
perhaps isotypes, of .1. Jackiana, A. trkhocoryna, A. cyrtopoda, A. stylosa 
and .1. glabra, and find no suitable characters worthy of specific separation. 
All these names have been listed above as synonyms of A. dumosa.

verrucosa, it appears that this species is confined to the "Upper Mountain- 
Zone" of Mt. Kinabalu, North Borneo. According to Stapf the altitude 
range of this zone is "6000-10000" feet. 

Except for the pubescence on the stamens, this species is entirely glabrous. 
The sturdy character of all parts of the plant is the first feature which 
impresses one. However, the verrucose-lenticellate character of the young 
branchlets, the very short and thick pedicels, the bisulcate midrib (lower 
leaf surface) and the thick leaves and petioles are other features which 
tend to distinguish the species from most of the other near relatives.

This species is closely related to ,1. caudatijolia Kob., but is separated 
by the 5-celled ovary and many ovules. It is safe to assume that in fruit 
A. colombonensis will produce many seeds. This assumption can be drawn 
from the size and number of ovules in the ovary.

Adinandra excel so appears very closely allied to the type-species 
.1. dmnosa, but can be distinguished by the sericeous buds, the alternate 
bracteoles, glabrous and subdeltoid, and the glabrous filaments. 

Distinguishing characters are: (1) the glabrous ovary and fruit; (2) 
leaves glabrous on both surfaces but sericeous in bud; (3) glabrous calyx- 
lobes and corolla-lobes; (4) glabrous, deltoid, alternate persistent 
bracteoles; and (5) glabrous filaments. 

Koorders describes the ovary as single-celled. However, dissections 
have shown it to be distinctly five-celled and multi-ovulate. The fruit is 
clearly five-celled also.

Sumatra: West Coast, Pajacombo Oeloe Air, alt. ca. 1100 m., 

The leaves of this new species resemble 
Kob., and A. borneensis Kob. both of Bo 
In A. myrioneura, however, the corolla is glabrous, the bracteoles caducous, 
and the calyx, ovary and style pubescent. In A. polyneura the corolla is 
pubescent, the bracteoles persistent, and the calyx, ovary and style glabrous. 
In A. borneensis the bracteoles are caducous and the calyx is pubescent. 

The petioles of the leaves of A. polyneura appear to be rather outstand- 
ing in that they seem to measure over a centimeter in length. This 
apparent length is caused by the gradual tapering of the blade along the 
petiole in a slight wing-formation. The actual petiole hardly exceeds in 
length that of the majority of species in this genus. 

Another interesting feature is the slight keel on the dorsal surface of the 
bracteole. Also, the pedicel appears 2-ridged, caused by the decurrence 
of the bracteole to the base, very much as a stem with decurrent leaves.

thick pedicels (5 cm. long) in pairs, and the large seeds makes this species 
one of the most outstanding in the genus. 

Ridley, in his original description, referred to the (lowers as "Flores non 
visi." However, buds were available for dissection. Considering the size 
of the seeds, so few in number, and the irregularity in the cells of the fruit, 
I felt compelled to dissect one of the few buds accompanying the type to 
prove to myself that this species belonged to the genus Adinandra. 

In the fruit, I found three cells, two of which were larger than the third 
and occupied most of the fruit. The third cell was compressed along the 
wall of the fruit aiid was seedless. The two large cells contained only 
three seeds between them. These seeds were three times the size normally 
found in the genus, very uniformly scrobiculate and typical of Adinandra. 
In the ovary of the llowerdnid. the same condition existed, namely two 
large cells and one smaller cell. The ovules, few in number, in the bud- 
stage were as large or larger than the mature seeds in most other species 
of the genus. 

Otherwise, characters in the !lower-bud appeared to be typical for the 
genus. The stamens numbered about S5, possessed hirsute anthers which 
were quite uniform in size and equalled the longest filaments in length. 
The corolla-lobes seemed thick in texture. 

On paper, this species is difficult to separate from A. Sarosanthcra. In 
most instances, .1. Sarosanthcra has terete branchlets. However, in rare 
cases in the species, one finds definitely angled branchlets. but not as 
pronounced as in .1. an^ulata where it appears to be the dominant character, 
extending to the branches themselves. 

Both species have .welled ovaries, not so well defined in ,1. angulata, 
and both have few but large seed- developing in the fruit. In both species 
the pedicels are elongated, somewhat flattened, and the bracteoles are quite 
minute. In A.angulata the veins are very prominent on both surfaces with 
almost equally pronounced reticulations. The bracteoles are quite deltoid 
and occasionally apiculate. In .1. Sarosanthcra the veins arc' obscure on 
the upper surface, only lightly conspicuous beneath, and the bracteoles are 
rounded. 

A second related species is A. laotica Gagnepain from Laos, Indo-China. 
In the latter species the ovary and fruit are 5-celled and the bracteoles are 
caducous.

Tree 25-30 m. high; branchlets brown, glabrous, appressed-pubescent 
when very voung, the buds densely sericeous. Leaves coriaceous, oblong- 
elliptic, 9-12 cm. long, 4-5 cm. wide (often much larger, 15-18 cm. long, 
6.5-7 cm. wide), obtusely acuminate at the apex, narrowed at the base, the 
lower portion of the margin entire, the upper part finely serrulate, glabrous 
when mature (thinly appressed-pubescent beneath when immature), the 
midrib conspicuous, the primary veins numerous, evenly spaced, con- 
spicuous on both surfaces, the petiole short, 5 mm. or less, somewhat 
winged on the upper surface, lower surface semi-terete. Flowers axillary, 
usually solitary, occasionally in twos: pedicel long, 3-4.5 cm., glabrous, 
quite 'erect, often nodding at the apex, the braeteoles 2, minute, quite 
rounded, opposite or slightly alternate below the calyx; calyx-lobes 5, 
somewhat coriaceous, imbricate, glabrous, varying from 5 X 6 mm. (outer 
lobes) to 8 X 12 mm. (inner lobes), the outer lobes weakly glandular- 
denticulate along the margin, the inner lubes with a membranous margin 
but no denticulations: corolla-lobes 5, obovate. 1.5-1.7 cm. long, glabrous 
or thinly pubescent on the external surface near the apex; stamens 30-50, 
up to 4-seriate. adnate to the base of the corolla, the filaments unequal in 
length, united, glabrous or nearly so, short (1-3 mm.), the anthers oblong, 
brownish, pubescent; ovary variable in pubescence, sometimes quite 
glabrous, pubescent at the apex, just below the style, or pubescent through- 
out, tapering at the apex into the style. 3-cclled. several-ovuled. Fruit 
globose, up to 2 cm. in diameter, glabrous or glabrescent, with a few 
straggling hairs at the apex, 3-celled. seldom over (> seeds in a single locule, 
sometimes only 6 in the entire fruit. Seeds fiat, hippocrepiform, up to 8 
mm. long. 

This species was originally described by Korthals (1S40) under the 
genus Sarosanthcra as S. execha. Later, Miquel rightfully transferred the 
genus to Adinandra. Since the species .1. excelsa Korthals already existed 
Miquel selected the name A. Sarosanthcra as most suitable. 



64 JOl K\ \l. OF THE ARNOLD 

The distinguishing characters of this species are: ( 1 ) 3-celled pubescent 
ovary (usually completely pubescent, occasionally pubescent near the apex 
only and rarely completely glabrous); (2) large globose fruit (up to 2 
cm. diam.). glabrescent. 3-celled or incompletely so, with large seeds up to 
cS mm. in diameter (2 or 3 to a cell); (3) filaments glabrous or nearly so 
with occasional appressed hairs on the exterior surface; (4) styles glabrous; 
(5) calyx-lobes glabrous; (6) corolla-lobes glabrous; (7) primary veins 
many (ca. 20 pairs) evenly spaced and quite scalariform in appearance; 
and (S) pedicel 3-4.5 cm. long. 

This species is nearly as widespread as A. dumosa Jack, extending from 
Borneo through Sumatra and some of the smaller Kast Indian islands up 
into the Malayan Peninsula. 

In Borneo it has been referred to as .1. Sarosanthera (and rightly so) 
by students of that island flora. In Sumatra, workers have called it 
A. lamponga and on the Malayan Peninsula it has been known as A. 
mat -rant ha. The last two names have been combined before. Koorders 
and Valeton ( 1896) suggested the very close relationship among the three 
and felt that they should be combined under a single species. 

In a species as widespread as this, and especially in this family, one must 
expect considerable variation. The ovary, in authentic material from 
Sumatra, is extremely variable. Material collected by J. E. Tcysmami 
s. n. from Pampong in southern Sumatra, the type-locality of .1. lamponga, 
presents a pubescent ovary. Rahmat Si Bona 0152 collected on the east 
coa>t of Sumatra near Asahan also has a pubescent ovary. Thorcnaar 111 
and AY///. I ml. For. Serv. b.b. 32125 collected miir Palembang, Sumatra, 
both in fruit, show the ovary to have been pubescent because, although 
glabrescent in maturity, there are vestiges of pubescence at the apex. 
Forbes 3191 collected in Sumatra (the localit) unknown to me), has a 
glabrous ovary. Cultivated in the Botanical (iarden at Buitenzorg, Java, 
under the number (VI-c 6), is a specimen with a distinctly glabrous 
ovary. Prom British North Borneo Elmer 2lr>2Q in mature fruit seems 
to be quite glabrous and one may assume that the ovary was glabrous or 
nearly so in the (lowering stage. • A Korthals specimen from Borneo labeled 
.1. Sarosanthera has ilowers with the ovary distinctly glabrous. 

Apropos of this discussion of pubescence, Koorders & Valeton in their 
discussion of A. lamponga (see reference above), stated that their descrip- 
tion was drawn up according to specimens in the herbarium of Koorders. 
They stated further that the living authentic specimen of .1. maerantha 
|Hort. Bog. VI-c 6 1 examined by them was identical with A. lamponga 
and they united the two species under . I. lamponga after comparison of 
A. maerantha with an authentic specimen \A.lamponga\ in "Herb. Bogor." 
and with the description b\ Micjiiel with which it appeared to them to 
agree fully. Only in the Sumatran specimen was the ovary truly pubes- 
cent. In Koorders' specimen the ovary was pubescent only at the apex. 
Koorders & Valeton stated that some specimens from Djampang-Koelon 
{Herb. Kds. 8159/3) differed through an entirely glabrous ovary and much 



19471 KOBUSKI, STUDIES IN THE THEACEAE, XV 65 

larger fruit 2.5 cm. X 2 cm. with the fruit walls 4 mm. thick. As for the 
leaves, the description of A. leiopetala Miquel agreed better with their 
specimen than that of A. lamponga. In the specimen of Teysmann in 
Herb. Hort. Bog., however, the leaves agree with the description of A. 
leiopetala in the projecting base. Koorders & Yaleton also feel that both 
species are very nearly related to J. Sarosanthcra Miq. 

I have vacillated considerably in my attitude concerning this species, 
going so far as to attempt to write them up separately. However, my 
final conclusion is that the whole group should be combined under a single 
species, ,1. Sarosanthcra Miq.. even though the variation, especially in the 
pubescence of the ovary, is considerable. 

In a few of the specimens, particularly those collected by E. J. H. Corner 
in Johore, the young branchlets are quite noticeably angled. From the 
size of the leaves and branchlets, especially Corner 2H581, I feel further 
that the specimens must have been collected from very vigorous young

The main difference between .1. corrtijolia and its variety . f. conlifolia 
var. strigosa lies in the permanence of the pubescence. Both entities are 
pubescent in the terminal bud. the very young unfolding leaves, and the 
young branchlets. In the species this pubescence appears to be very 
evanescent, the leaves and older brani hlets .shortly becoming quite glabrous 
or glabrescent. In the variety. I he disappearance of the pubescence is less 
rapid. In branchlets showing growth of over a single year and in the 
mature leaves a dense- strigose pubescence, perhaps permanent, is found. 

Because of this very apparent difference one is inclined at first to 
consider the two as separate species. However, when an accurate appraisal 
of all parts has been made-, the persistence of litis pubescence seems to be 
the single basis of separation. 

In the type. J. <*r .1/. S. Clemens 26229, the young fruits are subtended 
by calyces similar in size to those of the species. However, in /. & M. S. 
Clemens 40771, the second specimen cited, the calyx-lobes are somewhat 
smaller, measuring ca. S mm. in length.

According to Airv-Shaw's findings, the developed fruit of this species is 
two-celled with a single large seed in each cell. I have not had an oppor- 
tunity to observe this unusual feature but have examined an ovary from a 
bud of an isotype. A dissection showed the two cells in the ovary with a 
small number (approximately four) of ovules in each cell. This was the 
first species described with a two-celled ovary and fruit. The seeds are 
6-7 mm. long, adding another species to the small group in which the 
seeds are few in number and develop to a size at least twice that which is 
found in the majority of species in this genus. Tn this paper a second 
species with a two-celled ovarv. .1. nunkoknisis, is presented. This latter 
species has been collected on Alt. Xunkok. Mt. Kinabalu. in British North 
Borneo. The only evidence of relationship between these two entities 
appears to be the two-celled ovary. 

Besides the ovary, the features which are helpful in identification are: 
(1) nearlv sessile leaves with the petiole not more than 2 mm. long, and 
the apex long-acuminate: (2) pedicels very brief (1-2 mm. long), or the 
llowers subsessile; and (3) ovary and fruit long-pilose, the style glabrous 
except at the base.

also considered them glabrous. His description proved to be most detailed

glabrous at the margin; corolla lobes (tide King) ■■membranous, ovate, 
acute, glabrous, coimivent"; stamens (fide King) "about 50; filaments 
attached to the petals, short, glabrous: anthers narrow, the cells elongate, 
lateral; the connect iw sericeous with short glabrous apiculus"; ovary 
depressed-hemispheric, pubescent, 5 celled, mult i ovulate, the style gla- 
brous. Fruit ca. 1 cm. in diameter, globular, at first pubescent, later 
glabivscent. the seeds numerous, small, shining, dark. 

Anderson describes the leaves of this species as "finely mottled beneath 
with reddish-brown remotely denticulate glabrous." The leaves of the 
type are finely but obscurely mottled beneath with reddish brown patches. 
However, on no other specimen examined did I find the coloration. King 
(and I depended much on his excellent description) refers to the under 
surface of the leaf as "pale brown, dull, opaque, minutely rugulose when 
dry." This species seems most closely related to .1. intent rrima T. Anders. 
which has silky pubescent terminal buds and thinner leaves. In A. 
maculosa, the leaves are unusually thick, with the veins obscure, if at all 
obvious, on both surfaces. 

Characters which are helpful in determination are: (1) thick glabrous 
leaves, opaque beneath and very abruptly acuminate; (2) corolla-lobes 
glabrous; (5) bracteoles persistent, subrotund and pubescent; (4) ovary 
densely pubescent, 5-celled with the style glabrous; and (5) filaments 
glabrous.

This species is related to Airy-Shaw's .1. snhsr.ssilis of Sarawak. Both 
have two-celled ovaries. Although no fruiting specimen was available for 
this study, I feel from the small number and the large size of the ovules, 
that A. nunkokensis will probably have very few seeds. Adinandra sub- 
sessilis produces two seeds in fruit, one in each cell. The flowers in A. 
subsrssilis are nearly sessile, with pedicels only 1-2 mm. long, the bracteoles 
sepaloid, the calyxdol.es distinctly acute, the stamens uni-seriate and only 
4-6 mm. long, and the style 5-6 mm. long. The leaves are more finely 
acuminate at the apex, the petiole but 2 mm. long, and there are 12-14 
pairs of veins, prominent on both surfaces. 

In A. nunkokensis the flowers are briefly pedicellate, but the pedicels are 
longer (ca. 5 mm.) than those in .1. subsrssi/is and much thicker, the 
bracteoles are more rounded, the calyx-lobes subrotund. the stamens 
4-seriate and 7-11 mm. long, the style 11 mm. long. The leaves are 
acuminate but not as finely attenuate as in A. subscssilis, the petiole 6-8 
mm. long and there are only 6 8 pairs of veins.

Although three excellent specimens have been collected of this species, 
the material appears rather sparse. As a result few dissections were made. 
Since no open flowers were available, the buds were used. Hence 1 have 
refrained from recording measurements of such parts as corolla-lobes and 
stamens which were obviously not fully developed. However, the charac- 
ters which might be used in a key. other than size, have been recorded 

The three-celled ovary and fruit, with few ovules and seeds are important 
characters. The ovary of the bud (Corner 20010 type) exhibited few 
large ovules, hence one might anticipate fewer and larger seeds in the fruit. 
For the study of the fruit Comer 29376 was used. Here, in both fruits 
examined, it was found that a single large seed developed in each of the 
three cells of the fruit. Si/e is the distinctive element. Otherwise, the 
seeds were typical of the genus. 

All three specimens were collected by \\. J. H. Corner in Johore at 
varying dates during the year 1935. It is a pleasure to name this species 
A. Corneriuiia in his honor.

The species. .1. , audeitijoHa, as the name signifies, is characterized by 
the tail-like apex of the leaf. Furthermore, the leaf is chartaceous, rather 
than coriaceous, as is the case in most species. 

The material lacks flowers. The fruit, with its evidence of pubescence 
both at the apex and base-, shows that the ovary had been quite densely 
pubescent. This pubescence extends up the style. To what extent is not 
known, since all styles were broken near the base. The fruit is distinctly 
three-celled and the seeds large (ca. 7X5 mm.) and few in number (ca.

lightly appressed-sericeous on the median portion of the external surface; 
stamens smilingly 4-seriate, unequal in length, up to 10 mm. long, the 
filaments adnate to the base of the corolla, connate the length of the 
shortest stamen, free from that point, lightly pubescent on the inner surface, 
the anthers elongate, short-hirsute; ovary conical, densely pubescent, ca. 
3 mm. across. S-celled. pauci-ovulate, tapering .it l he apex into an entire 
style 7 S mm. long, pubescent nearly to the apex, ITuit quite globose, up 
to 1 cm. diameter, glabrescent with evidence of pubescence near the apex, 
few-seeded, the pedicel at this stage rugged and warty, the seeds light in 
color, m. () mm. long. 

I'ntil borrowed material from Kew was obtained this species presented 
considerable difficulty. In the original description. Korthals stated that 
the sepals were glabrous and the fruit 4- or 2-celled. My study revealed 
the sepals to be distinctly appressed-pubescent and the ovary definitely 
Tcelled. However, these conclusions were drawn from Malayan material 
rather than Sumatran. Dyer, in Hooker f.. IT Brit. India, 1: 2*2. 1874, 
stated also that the sepals and the leaves were glabrous. Later King (Jour. 
As. Soe. Bengal 59 (2): 190 | Mater. IT Malay IVnin. 1: 128]. 1890) 
remarked that the species was glabrous in all parts except the stamens, and 
Ridley (Id. Malay IVnin. 1: 194. 1Q22) gave the same impression. 

from all the material examined I find the species to be quite pubescent. 
Korthals gave this impression in his description, and authentic Korthals 
specimens from Sumatra, although lacking both tlovvers and fruit, show 
the young branchlets, buds and leaves to be pubescent. 

At first I felt that the British botanists were misinterpreting Korthals' 
species and perhaps were working with an entirely different species. 
However, the material from the Kew herbarium agreed with our own 
specimens in all instances, some actually being duplicates. The young 
branchlets, buds, under surface of leaves, pedicels, bracteoles, calyx-lobes. 
corolla-lobes, stamens, ovary and st\ le are all pubescent in varying degrees. 
The leaves, calyx-lobes, pedicels, bracteoles and fruit tend to become 
glabrescent. 

The apex of the leaves of the Sumatran material is much more tine- and 
long-acuminate than the apex of those of the Malayan material. In some 
of the Korthals specimens the acumen is drawn out to as much as 3 cm. 
and appears somewhat caudate. In the Malayan material, although 
definitely acuminate, the leaves are seldom as distinctive. Some workers 
have placed stress on the double arching of the veins of the leaves. This 
character varies considerably and is hardly stable. Also the wart-like 
condition of the fruiting pedicel has been stressed. As striking as this 
character happens to be. it is not found in the llowering material, for some 
reason not appearing until the developing fruit stage. 

Other characters which may be used in determination are (1) the 
alternate, small, persistent, triangular bracteoles; (2) the pubescent calyx- 
lobes and corolla-lobes; (3) the pubescent filaments joined the length of 
the shortest filament in series; (4) the pubescent, Tcelled ovary, pauci- 
ovulate. and the 3-celIed fruit, few and large seeded; and (5) the entire 
style pubescent almost to the apex.

In many characteristics. . I. , olUna resembles I. vrrrn, osa Stapf, to which 
it is closely related. both have bisulcate midribs on the under surface of 
the leaf, the more noticeable in .1. verrucosa. Roth species are quite 
glabrous and resemble .1. <lit»ios<i Jack in this respect. However, the two 
Bornean species have pubescence on the young terminal buds whereas in 
A. dutnosa the terminal bud is always strictly glabrous. 



1947] KOBUSKI, STUDIES IN THE THEACEAE, XV 77 

In A. verrucosa the leaves are larger, coarser, obtuse and bluntly emar- 
ginate at the apex, the midrib beneath is always glabrous. In A. collina 
the leaves are acuminate at the apex and a fine pubescence is found along 
the midrib on the under surface. The branchlets in the former species 
are very thick, measuring up to 4 and 5 mm. in diameter near the apex. In 
A. collina the branchlets are smooth, terete and measure only 1-2 mm. in 
diameter. The petiole in I. verrucosa is short and sturdy and when break- 
ing off from the branchlets leaves a large scar. The pedicels are very 
short and thick, seldom measuring over 5 mm. long, and often measuring 
the same in thickness. In ,1. collina the- pedicels measure up to 2 cm. or 
more (1 cm. in type), and are comparatively slender. The corolla-lobes 
of A. verrucosa measure 10-12 mm. in width while in those of A. collina 
the measurement is 6-8 mm. in width. Adiuandra verrucosa, to date, has 
been found only in the "upper-mountain" zone (6000-10500 ft.), of Mt. 
Kinabalu, as defined by Stapf, whereas .1. collina is found at low altitudes 
of less than 1000 ft. in the "hill-zone:' In the latter species, the majority 
of specimens cited were collected in Sarawak. 

In A. dutnosa, as far as I have seen, there is no tendency toward pubes- 
cence. The terminal bud is strictly glabrous. The terminal bud seems 
to be a criterion of this variable tendency toward pubescence. In species 
where the terminal bud is pubescent, especially when the pubescence is of 
the appressed nature, there is a distinct tendency toward glabrescence. 
As a result, one may find varying degrees of pubescence on the leaves and 
floral parts, making it quite difficult to use the character of pubescence in 
a key or as a delimiting factor. 

This same situation occurs in A. collina. The terminal leaf-bud is quite 
glabrous, yet one can find pubescence along the bisulcate midrib (which 
character is very obvious in the unfolding leaves) and along the margin. 
In the type cited above the specimen is quite glabrous and one must look 
most carefully to see evidences of pubescence. In other collections of the 
species, one may find distinct pubescence on the lower surface of the leaves 
and on the pedicels, bracteoles and calyx-lobes.

From the collections made on Mt. Kinabalu in British North Borneo 
by J. & .M. S. Clemens, this species seems to be the most widespread in that 
area. Collections were obtained from Dallas, at 3000 ft. altitude. 
Tenompak. Fenibukan, Marai Parai and Colombon River at 5000 ft. 
altitude and (birulau spur at 5000 and S000 ft. altitude. All specimens 
were collected at approximately 5000 ft. altitude with the exception of two 
from Dallas at 5000 ft. and one from Gurulau spur at 8000 ft. In most 
species of the genus the flower is white. In this species is found consid- 
erable variation in color ranging from a purple tinge through salmon and 
pink to pure white. Color in the stamens is also mentioned. 

The name .1. Clemensiae is selected in honor of Mrs. M. S\ Clemens who 
not only collected all the specimens cited for this species but many more 
spe< imens representative of various other >pecies in this genus. 

The ovary in the type-specimen. /. Cr M. S. Clemens 344S0 is more often 
four-celled than five-celled. At least, this was the case in the several 
dissections made for this study. However, a single dissection from 
Clemens -10122, collected in the same general locality, showed a five-celled 



19471 KOBUSKI, STUDIES IN THE THEACEAE, XV 79 

ovary. These two specimens, of all those cited above, are the only two 
in the flowering stage. The majority of specimens, obviously the same 
species, are in the bud stage. These buds, although sufficient for specific 
determination, are verv unsatisfactory for ovary-dissections. Two speci- 
mens /. & M. S. Clemens 50156 and 50979 are in the fruiting stage. From 
no. 50156, three fruits have been laboriously sectioned from apex to base. 
Although to all appearances these fruits are normal, they proved to be 
solid and woody throughout with only occasional slits where cells might 
have been expected. In /. & M. S. Clemens 50979 the fruit is found to be 
distinctly three-celled with few developed seeds. In this specimen the 
walls between the cells are very thick. Considering the fact that in most 
fruits the cell-walls are so fragile that it is often difficult to observe them 
with certainty, this thick-walled condition is most unusual. One may 
assume from these observations that .1. Clemensiae may have an ovary with 
the number of cells varying from three to five. 

The third fruiting specimen (7. & HI. S. Clemens 313S5) shows clearly 
a five-celled fruit with many seeds developed typical of the genus. In this 
specimen the cell-walls are thinner than those found in /. & M . S. Clemens 
50979. 

The small, thin, somewhat rounded leave- with long petioles present a 
character which makes this species easily recognizable.

When present, the open flowers of this species furnish the most outstand- 
ing character. The corolla is large, measuring 3 cm. across, white in color, 
glabrous, and the six individual lobes are 2 cm. in length. This is the only 
instance of a corolla with six lobes. Only two flowers were observed in 
detail, one each from J. & M. S. Clemens 32931, the type, and /. & M. S. 
Clemens 34482. In both cases six lobes were observed. Whether this 
number is uniform is questionable! According to the collectors, the stamens 

In this species and in A. impressa it is difficult to ascertain the number 
of cells in the fruit. In both species there is a similarity in the minute 
red seeds, which are so crowded in the fruit that they have penetrated the 
central axis, and the cell-walls appear to have been broken from the sides 
of the fruit. Also, in both cases, the placentae of the ovary (where it is 
easy to distinguish the five cells) appear blunt, with the many ovules 
nearly completely encircling the placentae. 

In keeping with the size of the other parts of the flower, the stamens 
are long. The filaments are free from each other their entire length, 
except at their base where they are adnate to the base of the corolla. The 
filaments of the inner or shorter stamens are somewhat geniculate and 
enlarged at their juncture with the anthers. However, in the longer or 
outer stamens, the filaments are very straight and uniform in width. 

Cited here dubiously are /. & M. S. Clemens 32610 and 51673 collected 
on JVIt. Kinabalu. Both specimens appear to belong to this species. 
However, both are specimens with smaller leaves ami both are incomplete,

The oblique, cordate base of the leaves is an unusual character in this 
genus and the most distinguishing feature (if the species. In this character 
and in the leaf-texture is found a striking resemblance to the species of 
the American genus Frcziera. The leaves of A. cordijolia Ridley, from 
Sarawak and British North Borneo, also have a cordate base. However, 
as Airy-Shaw states in his presentation, the true relationship of A. plagio- 
basis is rather with ,1. villosa Choisy and .1. coarctata Craib, which agree 
in indumentum and general leaf-outline. The indumentum in this species 
is unusual in that it is longer and more lax than the usual appressed type 
of pubescence found in the majority of species of the genus. 

My material of Richards 1191 is probably less copious than that from 
which Airy-Shaw drew his description. In the material examined here, 
the corolla-lobes measured only 13 mm. in length. Those described from 
the same number by Airy-Shaw measured 20 mm. long. I depended on a 
single flower for dissection, which, however, was in excellent condition.

Adimuulra inyrionriiru is outstanding because of the many primary 
veins on the under surface of the leaf extending nearly at right angles 
from the. midrib, at first very distinct but gradually fading towards the 
margin until nearly obscure. The bracteoles are alternate and quickly 
caducous, dropping before anthesis. The corolla-lobes are distinct in that 
the sericeous pubescence is found over the entire exterior surface rather 
than confined to a median portion as in the majority of the species in this 
genus. The stamens are many, the filaments closely joined for their entire 
length, densely pubescent on the exterior surface, and swollen to the width 
of the anther at the apex. The four-celled ovary is also an unusual feature. 
Only three dissections were made, but all showed true 4-celled ovaries, in 
which the placentae were clearly branched close to the axis. The cell-wall 
was deeply indented "opposite the point of branching.

Small tree 10-12 in., branching low, near the ground (fide Koorders); 
branehlets terete, sericeous, becoming glabrous; the terminal buds densely 
sericeous. Leaves coriaceous, elliptical to obovate 7-10 cm. long, 3.5-5 
cm. wide, usually acute at both ends, often obtusely acuminate at the apex, 
the margin of the upper hall" serrulate, pubescent when young on lower 
surface, along the midrib when mature, often glabrous, the petiole semi- 
terete, 4-5 mm. long. Hat on the upper surface, pubescent beneath. 
Flowers axillary; pedicels up to 2 cm. long, recurved, pubescent, often 
lightly so and near the calyx-lobes; bracteoles 2. caducous, ovate-lanceolate, 
4-5 linn, long when present (fide Koorders). alternate, the lower bracteole 
as much as 5 mm. below the calyx-lobes; calyx-lobes 5. imbricate, subequal, 
very obtuse. S- n mm. long, densely appressed-sericeous. the narrow margin 
membranaceous; corolla-lobes not seen, densely sericeous on the outer 
surface (fide Koorders); stamens (not seen) ca. 40, connate at the base, 
the filaments glabrous, the anthers sericeous; ovary densely sericeous, 
somewhat conical, .vcelled, tapering into a densely sericeous style. Mature 
fruit not seen, immature fruit (ca. 1 cm. diam.) densely sericeous. 3-eelled, 
multi-ovulate, the style densely sericeous, neither style nor fruit showing 
evidence of glabrescence. 

The closest relative to .1. java/iica (noisy is .1. dasyantha Korthals. 
Both are characterized by pubescent calyx-lobes, corolla-lobes and ovary. 
Also both have alternate, deciduous bradeoles. However. .1. javanica has 
a densely sericeous style, and the ovary and fruit are distinctly three-celled. 
On the other hand. .1. dasyantha differs in the glabrous style, the five-celled 
ovary and fruit. 

In most Malayan and Netherlands Last Indian species the presence of 
a three-celled ovary and fruit presages few ovules and even fewer seeds. 
Adinandra javanica appears to be one of the exceptions. The immature 
fruit examined shows that the developing seeds are minute and apparently 
many in number.

at the apex, cuneate at the base, glabrous, darker above, paler, lightly 
pubescent beneath, eventually glabrous, the margin lightly denticulate, the 
veins 10-12 pairs, anastomosing near the margin, the petiole 3-5 mm. long, 
pubescent beneath, eventually glabrescent. Flowers axillary, solitary; 
pedicel slender, recurved, 1.5-2.5 cm. long, thickened towards the apex, 
appressed-pubescent ; brae holes 2, quickly caducous, opposite, immediately 
below the calyx; calyx-lobes 5, imbricate, ovate, ca. 1 cm. long, 7 mm. 
wide, unequal, appressed-pubescent, the outer lobes broadly acute, 
glandular-denticulate along the margin, the inner lobes more nearly 
rounded, the margin membranaceous, entire; corolla-lobes 5, connate at 
the base, lanceolate, ca. 1.5 cm. long, 0.5 cm. wide, long-attenuate, tapering 
into an acuminate apex, sericeous on the median portion of the exterior 
surface; stamens in series, the filaments ca. 3 mm. long, adnate to the base 
of the corolla, joined at the base, sericeous on the apical half, the basal half 
glabrous, the anthers ea. 3 nun. long, densely hirsute, the apicule glabrous, 
2-3 mm. long, equalling the anther-cells in length; ovary sericeous, 
3-celled. multi-ovulate, tapering into the style, the style entire, sericeous 
diminishing in density toward the apex. .Mature fruit not seen. Imma- 
ture fruit somewhat globose, densely sericeous. 3-celled. 

The outstanding characters of this species are: (1) long-attenuate 
corolla-lobes, 1.5 cm. long, 0.5 cm. wide, tapering from near the base to an 
acuminate apex, the sericeous area tapering also; (2) stamens ca. 9 mm. 
long, with the filament, anther and apicule of about equal length, the 
apicule unusually long for the genus; (3) bracteoles quickly caducous; 
and (4) ovary 3-celled. sericeous. 

The closest relative is .1. />///< hophylla Hance. In the latter species the 
corolla-lobes are only 7 9 nun. long and, although they are acute at the 
apex, they do not taper gradually and continuously from the base to the 
apex; the stamens measure only 4 5 mm. long; the filaments are glabrous 
and less than a millimeter in length, the apicule rather inconspicuous; and 
the veins on the lower surface of the leaves tend to branch midway between 
the midrib and the margin. 

Craib records the ovary as two-celled. Only a single dissection was 
made in this study on a partially developed fruit. The results showed the 
young fruit to be clearly three-celled.

lobes more obovate, wider; corolla-lubes 5. connate at the base, ovate, 
acute at the apex. 10-11 mm. long. 5 (V mm. wide, pubescent over the 
entire exterior surface except along the margin: stamens ca. 35, seriate. 6-7 
mm. long, the filaments adnate to the base of the corolla and joined to each 
other, unequal, 1-2 mm. long, pubescent on the upper third, otherwise 
glabrous, the anthers ca. 4-5 mm. long, oblong, hirsute, the apicule ca. 1 
mm. long, often as long as the shorter filaments; ovary densely appressed- 
pubescent. tapering into a style densely pubescent at the base, less so near 
the apex, the stigma 4-parted, oblique, bruit globose, ca. 1 cm. in 
diameter, appressed-pubescent. 4-celled. many-seeded. 

The distinguishing characters of this species useful in determination are: 
(1) ovary appressed-pubescent, 4-celled; (2) style densely pubescent at 
the base, less so towards the apex; (3) stigma 4-parted. oblique; (4) 
corolla-lobes ca. 1 cm. long, ovate, acute at the apex, pubescent over the 
entire exterior surface except along the margin; (5) stamens 6-7 mm. 
long, the filaments very short, 1-2 mm. long; and (o) leaves elliptic, small 
(up to 8 cm. long), the veins 15-20 pairs, conspicuous on both surfaces. 

This species, along with .1. myrioncura Kob. of Borneo, has a 4-celled 
ovary. Just how consistent this character may prove to be will depend 
upon the examination of future collections. In other species, such as 
.1. Macgrcgorii Merrill from the Philippine Islands and .1. Clcmcnsiac Kob. 
from British North Borneo, where a 4-celled ovary has been noted, the 
character was found to be inconsistent. In .1. Clemensiae, where a 4-celled 
ovary occurred quite consistently in the type-specimen, more material was 
available for study, and the prevailing number of cells for the ovary 
appeared to be five. 

In .1. oblonga the Stigma is 4-parted and oblique. In .1. Mac^rr^orii 
the style was also 4-parted. Still, on the same specimen were found 
tlowers in wliii h the ovary was .S-celled. 

In its gross characters, this species resembles I. pari'ijolia Ridley very 
closely, the leaves appearing almost identical. However, it can be separated 
by the longer pedicels, the smaller acute corolla-lobes which are pubescent 
over the entire external sulfate, the very short filaments of the stamens, and 
the 4-celled fruit and 4-parted stigma.

base, glabrous above, lightly pubescent beneath, the pubescence more 
densely concentrated on the midrib and along the margin, conspicuously 
dark-dotted beneath, the margin revolute, lightly glandular-apiculate, this 
condition obscured by the pubescence, the veins 10-12 pairs, conspicuous 
on both surfaces, anastomosing near the margin, the petiole thick, 5-7 mm. 
long, densely pubescent on both surfaces. Flowers axillary, solitary; 
pedicels stout, recurved, ca. 5 mm. long, fulvous-pilose; bracteoles 2, 
opposite, immediately below the calyx, quickly caducous, when present 
ovate, ca. 3.5 mm. long, 8 mm. wide, pilose, ciliolate; calyx-lobes 5, imbri- 
cate, unequal, the outer lobes broadly ovate, 9-10 mm. long, 8-9 mm. wide, 
obtuse, pilose, the inner lobes ca. 13 mm. long, pilose, the margins dentic- 
ulate; the ovary subconical, ca. 4 mm. long, densely sericeous. 5-celled, 
multi-ovulate, tapering at the apex into a sericeous style glabrous only at 
the apex. 

Craib in his excellent description of A. coarctata mentions the ovary as 
being four-celled. I felt dubious about this character and sacrificed a 
developing fruit on the type-specimen to verify his finding. My single 
dissection showed four large well-developed cells with a fifth smaller, almost 
abortive cell, this latter containing developing ovules, however. 

Outstanding characters in this species are: (1) bracteoles quickly 
caducous, when present ovate, pilose, ciliolate, ca. 3.5 mm. long and 3 mm. 
wide; (2) inner calyx-lobes larger (ca. 13 mm. long) than the outer lobes, 
pilose, denticulate along the margin; (3) ovary densely sericeous, 5-celled, 
with one cell smaller than the others, multi-ovulate; (4) style entire, gen- 
erally sericeous, glabrous at Ihe ape\: (5) terminal buds densely fulvous- 
pilose; and (6) leaves with a generally thin pubescence on Ihe under 
surface, the pubescence densely concentrated on the midrib and margin 
obscuring the glandular-apiculations along the margin. 

Although the corolla-lobes and stamens have not been described for this 
species, from the type and distribution of the pubescence one may expect 
the former to be pubescent. 

This species is so closely associated with .1. glischrotoma Handel- 
Mazzetti and its varieties of China and Indo-China that later collections 
may prove it to be no more than another variety in this complex. How- 
ever, until these further collections are made, it is best to continue the 
species in its present status.

minute, 4-5 mm. long, the filaments only ca. 0.5-0.S mm. long, joined at 
the base, glabrous, the anthers oblong, very densely sericeous; ovary and 
style elongated, only 5 mm. long over all. densely sericeous at anthesis. 
Fruit globose, ca. 1 cm. diameter, densely sericeous, topped by a persistent 
sericeous style 1.5 cm. long. Seeds minute, dark brown. 

The outstanding characters of this species are: ( 1 ) corolla-lobes lightly 
sericeous, shorter (6-8 mm. long) than the calyx-lobes (7-9 mm. long); 
(2) stamens minute, ca. 5 4 mm. long, the filaments glabrous, very short 
(0.5-0.8 mm. long), the anthers so densely sericeous that their outline is 
difficult to discern; (5) pedicels sturdy, up to 5 cm. long in fruit: (4) 
bracteoles caducous, when present 4 mm. long; and (5) ovary, fruit and 
style densely sericeous. 

From 1887 to l')25, this species had been considered synonymous with 
A. intc£crrima T. Anders. Pierre felt the two entities were identical and 
in his treatment of .!. intc^crrima probably used the type of A. phlcbophylla 
(Pierre 60S) in describing and illustrating .1. in/c^crrioia for his Fl. For. 
Cochinchine (2: t. 125. 1887). It is safe to assume that this specimen 
provided the material for both his description and illustrations, since they 
agree perfectly. Craib (1025). was the first to draw attention again to 
.1. phlebophylla and he returned it to its specific status. 

Adiuamira phlcbophylla is more closely allied to A. lutcscens Craib than 
to .1. intc\>crrima. In leaf-characters these two species are almost iden- 
tical. However, Craib's species has a much longer corolla (1.7 cm. long) 
and the filaments are approximately lour times longer and more in propor- 
tion with the anthers than those in .1. phlcbophylla. 

The number of cells of the ovary is not known. Even though isotypes 
of the species were available for this study, the- material was so poor that 
I was not able to make dissections which would add to this knowledge'. 

The species is treated in this portion of the- study rather than with the 
Chinese species since its relationships are with this group and also because 
of the former confusion of its association with A. integcrrima.

This species has been little understood and frequently misinterpreted. 
My early conclusions were based on a single specimen, Corner 31595, in 
the Arnold Arboretum. However. I found myself unwilling to accept my 
own interpretation and made a late appeal to Kew for a secondary loan 
of representative authentic material of this species. To my surprise and 
satisfaction Corner 31595 was included in the loan along with Wallich 
1454, the latter specimen probably the most renowned in this species. 

I was embarrassed when I realized that a psychological element had 
played an important part in my reluctance to accept the species at first. 
I mention this unscientific incident, since it may help to explain the dubious 
position the species has held in the past. Considering some of the very 
pubescent species such as A. glischroloma Handel-Mazzetti, I was very 
disappointed in the amount of pubescence on .1. villosa when confronted 
with the actual type. I had expected a much more pubescent species. 
Although the name is appropriate, the species is hardly more villous than 
many other species in the same geographical locality. 

All the above cited specimens arc- in the fruiting .stage; hence complete 
descriptions of corolla-lobes and stamens are still wanting. King in his 
"Material for a Malayan Flora" gives rather a complete description of the

because of the incomplete material in the type specimen 1 was at first 
unwilling to describe this new species. However, after careful study it 
appears to be distinct from the other species in its geographical area. The 
material, even though incomplete, is sufficient to permit a technical 
description, and hence I finally have decided to include it in this study. 

The name .1. bicuspidata is derived from the bicuspidate appearance of 
the anthers. In some species studied, the connective projects beyond the 
anther cells, causing anthers to appear apiculate. In other species, the 
anther cells are Hush with the connective, causing the ant tiers to appear 
truncate. In this new species, the anther cells project sharply above the 
connective, giving a bicuspidate appearance to the anthers. 

Other characteristics which lend distinction to this species are: ( 1 ) the 
chartaceous leaves with the veins distinctly reticulate- on both surfaces; 
and (2) the long ferrugineous pubescence o\ the anthers, ovary and style. 
The pubescence of the style is further unusual in that it extends the entire 
length of the style, obscuring the stigma.

In the type specimen the flowers were immature, and hence the measure- 
ments of most iloral parts cited above are subject to change when more 
complete material is available. It appears that this species may be very 
rare, since it has been collected only once, and that nearly sixty years ago. 

Unfortunately, the true number of cells in the ovary could not be 
ascertained. Although two dissections had been made, in both cases the 
cell-walls of the ovary were too indistinct to permit one to say with 
assurance just what their number might be. I am inclined to feel that 
the ovary is five-celled, but of that I am not certain. Because of the

in the key and is placed at the end of the Indo-Malaysian species. 

At Kew, this species had been associated with .1. villosa (noisy. How- 
ever, the chartaceous, reticulate leaves, the bicuspidate anthers, the glabrous 
filaments and the opposite bracteoles all distinguish .1. bicuspidata from 
the elder species.

Ad'niandra Brrfr/d/i and the following species. .1. crlrbiru, were offered 
by Koorders as new species with accompanying descriptions far too brief 
for satisfactory study without type-specimens. It may be that the types 
were also incomplete. Although both species appear to have been described 
from fruiting material, very little information concerning the fruit is 

The interesting feature in the above description (which is merely a 
translation of the original), is the petiole of the leaf. Koorders mentions 
the leaf as being decurrent into the petiole 2 cm. long. In the above-cited 
sterile specimen, the petiole is hardly much over 1 cm. long but the leaf- 
blade is decurrent into the petiole and this decurrent condition persists 
along the branchlet. The specimen, although sterile, evidently has been 
collected from a vigorous young shoot, the leaves being of considerable size.

The information offered by Koorders in his description of this species 
is too brief, and offers no details that might not be applied to any but the 
most exceptional species in the genus. He does state, however, that in 
the Kew Herbarium there is a specimen collected by Beccari in central 
Celebes which is supposedly identical with his type. From the Kew 
Herbarium was obtained a specimen collected by Beccari which may or 
may not be the specimen in question; hence it is cited here dubiously. 
The pedicels in the Beccari specimen measure not more than 2.5 cm., 
whereas Koorders records the measurements as 3-4 cm. He also states 
that the leaves are glabrous to the naked eye but laxly pilose under the 
hand-lens. The Beccari specimen is quite glabrous. However, the ter- 
minal leaf-buds are appressed-pubescent which would indicate that the 
very young leaves are pubescent, on the under surface at least. Only by 
an examination of the actual type can one expect to gain a concept of 
this spec ies.

A discussion of this species is quite difficult since the only available 
reference is the sketchy original description by T. Anderson. A note, 
perhaps the original manuscript of Anderson, on an otherwise blank her- 
barium sheet in Kew states, •possibly a native of the Malayan peninsula. 
Wallich's specimen is the only one that exists and was obtained from the 
Madras Herbarium and bears no locality. It is probably one of those 
plants collected by Konig during his visit to the settlements in the 
Malayan peninsula." Considerable doubt as to the origin of the type 
existed at the time of the description, and, from the literature examined, 
it appears that no worker has associated any material collected later with 
the species A. cremdata. 

Both Szyszylowicz and Melchior in their treatments of the Theaceae in 
"Die Naturliche Ptlanzenfamilien" incorporated this species in their work. 

Unfortunately, the original description of the species is such that it 



1947] KOBUSKI, STl DIES IN I UK THEACEAE, XV 93 

might be applied to any number of species in the Malayan region. Because 
of this lack of a single distinctive feature, and the fact that the type is in 
Madras rather than in one of the Malayan herbaria, its true identity has 
been lost and will continue to be until opportunity can be afforded some 
worker to study the type. 

Ridley 4801, deposited in the U. S. National Herbarium and collected in 
the Singapore Garden Jungle, may belong to this species. The distinguish- 
ing feature of this specimen is the decided crenulation of the leaf-margin. 
It is not a good specimen. There are no terminal buds and the partially

DOUBTFUL SPECIES 

65. Adinandra cordata Choisy in Mem. Soc. Phys. Hist. Nat. Geneve 1: 112 (Mem. 

Ternstr. 24). 1855. 
This species, mentioned only once and then doubtfully by Choisy, is 
based upon a reported species by Gaudichaud from the Hawaiian Islands. 
There has been no other record of Adinandra from the Hawaiian Islands 
since that time, hence one is led to believe that Choisy erred in his generic 
designation. The subsessile cordate leaves lead one to believe that Choisy 
may have had in mind Eurya sandwicensis A. Gray. This is merely a 
supposition, since no material has been available for this study. However, 
Choisy 's brief description does apply for the most part to specimens 
examined of E. sandwicensis.

The knowledge of this species is very limited. In Misc. Papers Indo- 
China is reproduced the original description. There, on p. 295, Adinandra 
sylvestris is described as "Bacca trilocularibus. Suka beranak. Malay. 
A large forest tree at Moco Moco." On p. 302 of the same volume. Sir 
J. D. Hooker, in a note to the editor states. "Adinandra sylvestris. Not

This species was originally described as Tcmstrocniia bancana by Miquel 
in 1862. In 1890, King, thinking the species an Adinandra, transferred 
it to the latter genus under the name A. Miquelii. Later, Ridley (Fl.

name, Ternstrocmia bancana Miquel. In the meantime, Durand and 



AFRICAN SPECIES 

Two species of Adimuidra have been described from Africa. The first 
species, .1. Mamiii Oliver (1868). was collected on St. Thomas Island off 
the west coast of Africa in the Hay of Guinea, and the second species. .1. 
Sc/tlirbniii Melchior (1934). was collected in Tanganyika Territory in 
eastern Africa, a span of nearly the whole African continent separating 
the two entities. It appears from the literature that both species have 
been collected only once. Although these two species differ considerably 
in many features from the Indo-.Malaysian and Papuan groups, on the 
other hand they possess many interesting characteristics in common with 
the latter and are closely related. Among the outstanding characters in 
which they differ from the other groups are: (1) stamens in a single 
series, the filaments glabrous, free except at the very base, the anthers 
glabrous, subsagittate; and (2) corolla lobes three times longer (85-50 
mm.) than the calyx-lobes, connate at the base only, otherwise free. 
disposed in a pseudo-tube, the apices of the lobes arching over the pistil 

Szys/ylowicz (1898) created a section, Kleutherandra, for A. Mannii 
based on the free filament- ami supposedly separating this species from all 
other specie's of Adinandra. Melchior (1925) continued this section of 
Szys/ylowicz and in 1084 added to the section the species .1. Scfilicbrnii. 
This character, if meant to separate these two species from all others, is not 
well chosen, since nearly every species in China must be included. The 
most outstanding characters to my mind are the glabrous subsagittate 
anthers and the corolla-lobes arranged in a tube. 

Xo formal key is necessary to separate here these two species, '['heir 
differences are mentioned in detail in the discussion following the

base, at which point they are joined together as well as adnate to the base 
of the corolla; and (3) corolla-lobes linear-oblong, connate at the base 
only, but connivent their entire length presenting a tube like appearance. 

The characters which separate A. Mannii from .1. Schlicbenii are: (1) 
inner calyx-lobes glabrous and entire; (2) corolla-lobes subrotund at the 
apex; (3) bracteoles longer, measuring 7-8 mm. in length; (4) ovary and

This species has been described so minutely that it can be separated 
easily from the preceding species, even though the type has not been seen. 
It is fortunate, since the type may not be in existence any longer. 

Ad'niandra St hl'u h< mi Melchior was collected by H. J. Schlieben in 
Tanganyika Territory in eastern Africa, far removed Horn the Island of St. 
Thomas in the Hay of Guinea where J. Maitnii was collected. 

According to Melchior, the type specimen is numbered 3175 and was 
found growing on the northwest side of the I luguru Forest in Morogoro 
(Tanganyika Terr.), at an altitude of 1900 m. The flowers are orange 
and red in color. On December 2S, 1932. the plant was in both ilower and 
fruit. 

The characters separating this species from .1. Mannii are: (1) inner 
calyx-lobes pubescent and ciliolate; (2) corolla-lobes acute at the apex; 
(3) bracteoles unequal and shorter, measuring 3 and 5 nun. in length; (4) 
ovary and lower half of the style sericeous; and (5) stamens twice as long.

PAPUASIAN SPECIES 

To date, three species have been described from New Guinea. .1. Forbcsii 
Baker. .1. Bru.ssii Kobuski, and .1. caloscricca I dels. The last named 
species has been transferred to the new genus Anhholdiodoidron, which 
is midway between Cordonia and Ad'nuuidra in characters. The styles in 
An hholdiod* ndroii are free, very short, and recurved, resembling those of 
Cordonia. In wood-structure the genus resembles Adinandra. It is not 
known as yet whether the fruit is dehiscent or indehiscent. From the 
appearance of the ovules one would not expect the seeds to be winged. 

The first two species mentioned above belong, according to the collector, 
L. J. brass, among the very large trees of New Guinea. They are closely 
related to each other and are separated from the Indo-Malaysian species 
by their large, fleshy purple corolla-lobes and their very numerous (50-60).

istics separating the two species from each other are noted in the discussions 
following their descriptions.

the margin; stamens ca. 56. 5-seriate, 10-14 mm. long, filaments only 
lightly adnate to the base of the corolla, connate, densely sericeous on the

lightly hirsute, oblong, subequal, 4-5 mm. long; ovary globose, glabrous, 
ca. 5 mm. long. 6 mm. wide, attenuate at the apex into an entire style, 
5-celled, multi-ovulate. Fruit not seen. 

Adinandra Forbesii can be separated from A. Brassii by the following 
characters: (1) leaves oblong-elliptic, acute at both ends, conspicuously 
veined on the under surface; (2) pedicels up to 4.5 cm. long, glabrous, 
covered with many conspicuous lenticels; (3) bracteoles opposite; (4) 
corolla-lobes glabrous; and (5) calyx-lobes recurved, even in the bud. 

This species is closely related to A . Brassii and has many characteristics 
in common with it, especially in the floral parts. In both species the 
corolla-lobes are fleshy, the calyx-lobes hardly more than 5 mm. long and 
thinner than the corolla-lobes, the stamens are conspicuously 5-seriate, long 
(up to 15 mm.), and densely sericeous. 

According to Baker, Szyszylowicz, and later, Melchior, the stamens are 
described as "pentadelphous" or in "five-bundles." True, they vary in 
length according to the series but are not distinctly in bundle formation. 
They appear joined in a single tube. Perhaps, in drying or in boiling 
they may be broken up into groups, but my study showed them more 
characteristically in an unbroken tube-formation.

Adinamlni Hrassii is listed by brass as one of the large trees of New 
Guinea. It is a very distinctive' species characterized by thick, dark, scaly 
bark, light brown or red-brown sap-wood and purple heart-wood. The 
corolla-lobes are purple, and much more fleshy than the Malayan and 
Chinese species; the calvx-lobes. on the other hand, are smaller and 
thinner. 

Adinandra Brassii can be separated from .1. Forhr.sii, its closest relative 
and the only other species known at present from New Guinea, by its 
obovate or subrotund leaves which are not oblong, the much less con- 
spicuous veining, and the fine appressed-pubescent corolla-lobes. 

When first described this species appeared very outstanding because of 
the densely hirsute anthers and filaments. Since baker, in describing A. 
Forbcsii, did not mention pubescence on either the corolla-lobes or the 
stamens. I assumed them both to he glabrous. An examination of the type 
of .1. Forbcsii showed, as far as the corolla-lobes were concerned, this 
assumption to be correct. However, the stamens (both anthers and 
filaments) are so densely sericeous that they appear to be the most 
noticeable characteristic of the flower.

BY L. J. BRASS, I* 



With jour text-figures 

This is the first contribution to an account of the spe ■mens of Cypera- 
ceae collected in New Guinea chiefly by Mr. L. J. Bras- during the Arch- 
bold [expeditions between lQ.vi and 1939. Included abo in the treatment 
are some other specimens from New Guinea and the Solomon Islands from 
various collections. I am particularly grateful to Prof. Klmer D. Merrill, 
of the Arnold Arboretum, tor the opportunity to stud) the brass collection, 
and to Dr. Lily M. Perry for copies of much literature unavailable to me. 
To Mr. A. J. Jessep and Mr. J. H. Willis I am indebted for the loan of 
specimens and literature from the National Herbarium of Victoria, Mel- 
bourne (cited as herb. .Melbourne), and to Mr. W. Hartley for the loan of 
a set of the specimens collected by Mr. C. E. Carr, now in the herbarium 
of the Council for Scientific and Industrial Research, Canberra (cited as 
herb. Canberra). 

Unless otherwise indicated, the type-specimens of new species are in the 
Queensland Herbarium. Brisbane (herb. Brisbane) and duplicate-types in 
the Gray Herbarium of Harvard University, Cambridge, Mass. 

The present paper deals with the genus Ctirrx, and in this genus I have 
received valuable help from Mr. E. Nelmes, of the Herbarium, Royal 
Botanic Gardens, Kew, England, who has been studying the Malaysian and 
Australasian species of the genus for some years. The arrangement of 
species here follows that in Kukenthal's well-known monograph in Das 
Pflanzenreich IV.20. 1909, but some variations of his treatment have been 
found necessary at this later date. The specimens have been critically 
compared with copious Australian material, but the comparison with 
Malaysian material has been much less extensive and considerable reliance 
has had to be placed on descriptions alone.

Netherlands New Guinea- 9 km. northeast of Lake Habbema, Brass 10255 
(type), October 1038, alt. 2800 m„ massed on open beaches of small stream in forest. 

This species is most nearly allied to C. rhizopoda Maxim., from Japan, 
differing in the more densely-flowered female part of the spike with broader 
reddish brown (not green) glumes, the nut more obtuse at each end, and 
perhaps also in the shorter male part of the spike. Ohwi, in Mem. Coll. 
Sci. Kyoto Imper. Univ. ser. B, 11(5) : 443. 1936, has erected a new section 
Rhizopodae Ohwi for C. rhizopoda, but C. eremostachya appears to agree 
better with the characters of the Circinatae, under which Kukenthal 
arranged C. rhizopoda in I'tlanzenr. 1V.20: 98. 1909. C. eremostachya 
also appears to be closely allied to C. Petelotii Gross, but to judge from 
the description the latter has a narrower spike but longer utricles (5-6 
mm.). No mention is made of a rhizome.

to some forms of C. nhinata Murr. ( ('. stdhihita Good.), but has narrower 
leaves and longer utricles with a relatively longer beak deeply .split on the 
back and with entirely smooth margins. The split on the back usually 
appears as a narrow brown furrow, as the result of the overlapping of the 
edges.

Previously known to me with certainty only from Queensland. Kiiken- 
thal, in Pflanzenr. 1V.20: 264. 1909. regards C. Dietrkhiae Boeck., C. 
fissilis Boott. and C. indica L. var. Mihici C. B. Clarke as synonymous, 
treating the group as C. indica var. fissilis (Boott) Kukenth. Car ex 
Dietrkhiae differs from C. indica L. in having shorter awns to the brac- 
teoles. bright brown (not pallid) male glumes, and less spreading, le.v*

HMO, and Carr's collection under ('. indka L.. in Bot. Jahrb. 69: 262. 1938. 
The species differs from C. indka L. and its immediate allies (subsect. 
Tnr-itiular Kiikenth.) in that the utricle is not olivaceous, is by no means 
inflated, and is gradually attenuated into its beak, and differs further from 
C. indka itself in that the pistillate glumes are only shortly aristate. From 
C. Rafflcsiana and its allies (subsect. Ilispidnlac Kiikenth.) it differs in the 
stouter more rigid panicle and in that the utricle is but sparsely scabrous 
and then only on the narrow beak. By reason of the non-inflated utricle 
not abruptly narrowed into its slender only slightly scabrous beak, this 
species seems best placed in subsect. Gnu ilirostres Kiikenth., but it is 
readily distinguished by its pallid shining mature utricle. Carr's specimen 
is a somewhat immature plant with a culm about 50 cm. high and leaves 
about 7 mm. wide.

C. Rafflcsiana Boot! var. cmitinua (C. B. Clarke) Kiikenth. Kiikenthal 
also cites Brass 5323, 4391, and 4623 as belonging to this form; of these 
Brass 5323 serves as the type of the abundantly distinct C. lamprochlamys 
S. T. Blake, while nos. 4391 and 4623 arc referred below to C. neoguineen- 
sis C. B. Clarke. MacGregor's specimen was referred to C. fissilis Boott 
by F. Mueller, in Trans. Roy. Soc. Vict. 1(2) : 36. 1889. 

Kiikenthal's earlier opinion that C. continua C. B. Clarke is specifically 
distinct from C. Rafflesiana Boott seems preferable to treating it as a 
variety of the latter. The specimens seen from New Guinea and the 
Philippine Islands seem to form a homogeneous series. The species extends 
to the eastern Himalayas.

The specimens cited show some variation between one another, par- 
ticularly as to the size of the utricle. Brass 9210 and 4623 have small 
utricles 2.5-2.8 mm. long, while on Brass 108S2 and MacGregor's specimens 
the utricles are 2.7-3.5 mm. long with longer more slender beaks. The 
type-specimen is described as having utricles 3 mm. long with the beak 
prominently toothed at the tip. All our specimens have an entire or 
emarginate tip of the utricle. Mr. E. Nelmes does not mention this 
character, but tells me that apart from the size and rather stouter beak the 
utricle of Brass 9210 is rather similar to that of the type and that the 
glumes are much alike. In view of the variation on Brass's specimens I

MacCregor's specimens have coarser leaves up to 10 mm. wide and the

closely allied to C. continua, but it has more loosely (lowered spikes with 
the utricles more abruptly contracted into a more slender trigonous promi- 
nently decurved beak, while the shorter stiffer leaves and bracts (the 
former usually not exceeding the base of the inflorescence, the latter only 
about as long as the partial panicles) and the shortly aristulate to muticous 
braiteoles give a different jacks to the species.

Carcx melanophora is evidently close to ('. sanncakctnisis kukenth., but 
differs in the nodeless smoolh stems, smaller partial panicles, smaller 
spikes, longer and perhaps more distinctly nerved utricles which are scab- 
rous rather than hispid except on the margins of the beak, and perhaps 
also in the development of stolons. The three collections cited above are 
unlike each other at first glance, but they are indistinguishable as to their 
spikelets and appear to reflect differences of habitat. All specimens show 
at least a piece of a stolon. The type-sheet consists of two pieces 3 and 4 
dm. high with narrow partial panicles the lower of which are distant and 
long-peduncled. Brass & Myrr-Drrcs 100S0 consists of tiny plants up to 
5 cm. high; they are immature but evidently represent starved plants. 
The third collection is intermediate with plants 7-13 cm. high, not quite 
mature, with fairly dense inflorescences with the lower partial panicles 
shortly pedunculate and thicker than in the type. The utricles are some- 
what "larger than in the type. 4-4.5 mm. long and 1.1 1.2 mm. wide. It 
would appear that the usual length of the utricle of the species varies from 
3.5 to 4.2 mm.

Brass 7.»-SY> was determined by Kiikenthal. in Hot. Jahrh. 69: 264. 1938, 
as C. Grarjlrana Hoott, from which it differs in the narrower leaves, fewer 
shorter coarser spikes, and rather longer utricles acute at the base and with 
more numerous nerves. It appears to be closely allied to (". Pandanus 
Ohwi. in Hot. Mag. Tokyo 56: 214. 1942. from Netherlands New Guinea, 
but has much longer leaves with more persistent sheaths, commonly cuspi- 
date glumes, and darker coloured, rather smaller, elliptical (not obovate) 
utricles punctulate in the upper part. It is also close to C. phUipp'mcnsis 
Xelmes. in Kew Hull. 1938: 109. 1988. differing in that the terminal 
spike is usually male, in the rather more slender spikes, in the ovate rather 
than obovate glumes, and in the smaller elliptic (not obovate) smooth 
paler coloured utricle which is less obtuse at the base. 

On the type specimen, selected as such because of its full maturity,

there are 13 spikes and the glumes are muticous or shortly pointed. Brass 
10734 measures 22 cm. to the top of the inflorescence and has 10 spikes 
rather shorter than those on the type (up to 3.5 cm. long), with which 
it otherwise agrees. Brass 4386 is similar to the type in 
is not quite so mature; it carries 10 spikes and the gl 
prominently awned. Brass 10559, also with 10 spikes, i: 
the uppermost spike has a few female flowers at the base.

cited above, particularly firass 9330, agree so well with the description that 
there seems no doubt they are conspecitic. The following notes on these

a very short sheath; and the utricles vary from 3 to 3.0 mm. long.

Papua: Central Division: Mt. Albert Edward, Brass 441 S (type), May-July 



Described by Kiikenthal as a variety of ('. bulbostyUs Kiikenth. non 
Mackenzie (C. montivaga S. T. Blake), but it differs greatly from that 
species in appearance, in I he stiffer broad leaves, included culms, sheathing 
bracts, pedunculate female spikes with muticous glumes (usually not 
muticous in C. montivaga), and rather shorter very shortly beaked densely 
hispidulous yellowish utricles. The rhachilla is well developed and is 
sometimes so long as to be ex.serted from the utricle when it bears another 
utricle, sometimes well developed, sometimes rudimentary. At times the 
glumes appear cuspidate due to the inrolling of their upper margins. 

In Bull. Jard. Bot. Buitenz. III. 16:318. 1940, Kiikenthal cites three 
collections under his C. bulbostyUs var. hispidula. namely J. & M. S. 
Clemens 29005 and Clemens 32344 from Borneo and Brass 4418, without, 
designating the type. In the same year, in Bot. Jahrb. 70: 464, the same 
description is given, but the collections are cited as follows: 

"Sudostl. Neu-Guinea: Mt. Albert Edward (Brass n. 4418'). 

Area: Mrit. Nordborneo, Mt. Kinabalu (Clemens n. 29005!; 32S44!)." 



112 JOl R\AL OF THK ARNOLD ARBORETUM [vol. wvin 

Under these circumstances we may consider that in the latter publication 
Kiikenthal emphasised that Brass 441S represented his variety, so that this 
may be regarded as the type of his trinomial. I have not seen the Clemens 
specimens. In any case the type of the binomial C. brcvis is the sheet of 
specimens of Brass 4418 in herb. Brisbane.

I do not see how these specimens differ from the general trend of the 
species in Kastern Australia, unless the utricles are somewhat less pubescent. 
The length of culm varies considerably, sometimes even on the same plant, 
and evidently has no taxonomic importance in this species. I have seen 
no authentic specimen of subsp. Roylrana, which is said to have somewhat 
scabrous culms; the other characters described are to be found in 
characteristic C. breviculmis.

spikes with more spreading utricles. Kiikenthal describes the spike of

differ from the description in that the spikes are up to 6 cm. long, sometimes 
all distinct from one another (not up to 4 cm. Ions with the two uppermost 
female ones fastigiate). in that the utricle is only about 3.5 mm. (3.3-3.6

break up into fibres, while an elongated rhizome appears sometimes to be 
present. The inflorescence of Brass & Mycr-Dras 0070 agrees pretty 
well with kiikenthaks description, but on this specimen the basal sheaths 
are broken up into fibres. In the other collection the plants are more 
elongated with longer and more distant spikes. The basal leal-sheaths are 
but little disintegrated and evidence of an elongated rhizome is present.

in the nearly smooth rigid less flattened narrower leaves, the short 
peduncles, the longer glumes, the longer long-stipitate utricles less suddenly 
contracted into the beak and in the nut much shorter than the utricle. 
Currx acrophila is closely allied to C. teinogyna Boott, from India and 
Burma, but differs in the denser iniloresrrnce, the shorter peduncles, the 
utricles with a longer stipe and more gradually narrowed to a shorter beak 
with shorter teeth, the shorter nut and rather shorter stigmas. It is also 
evidently close to C. spathaceo-bracteata Kukenth. , in Bot. Jahrb. 70: 466.

leaves, 2-3-nate (not 3-5-nate) -pikes, longer not conspicuously dilated

There remain three collections of which the specimens are not sufficiently 
complete for satisfactory determination. Brass 9235, from sunny bogs, 
Lake Habbema, 3225 m., consists of small plants evidently allied to C. 
st run ph xlla Wahlenb., of the Northern Hemisphere, but the utricles are 
far too undeveloped for certain determination. Brass 11540, from the open 
banks of the Hele River, 2200 m.. is an Indocarcx allied to C. filicina Nees

HOW \KI). SOME PLANTS OF CUBA 

NOTES ON SOME PLANTS OF CUBA

With two plates 



The plants described in this paper were collected in Cuba in the sum- 
mer of 1941 by .the author. Headquarters during this collecting trip was 
the Atkins Institution of the Arnold Arboretum, at Soledad in southern 
Las Villas province. I am grateful to Mr. David Sturrock and the admin- 
istration of the Soledad gardens for their many courtesies and for the 
privileges of using the facilities of the station. 

Most of my collections during that summer were made in the San Juan 
and Trinidad Mountains and in southern Las Villas province. One short 
trip was made to the Oriente province with Brother Leon, of the Colegio 
de la Salle of Havana, and many of the new entities described in this paper 
were collected then. The trip to the Oriente and the territories in which 
collections were made were described by Brother Leon under the title, 
"Excursion Botanica a las Tierras de Moa" (De La Salle No. 225: 23-29. 
1941). The collection numbers cited are my own. I am grateful to 
Brother Leon for the pleasure of accompanying him on that trip and also 
to Mr. George Bucher and Mr. J. R. Grist for the hospitality and assistance 
offered during our stay at Moa. 

The description of a new species of Neobracea was supplied by Dr. 
Robert E. Woodson, Jr., of the Missouri Botanical Garden, and I am 
grateful to him for examining this material and supplying the name.

l\tijan?ti nij>t iisi\ is similar to A', prrstonit nsis Knuth. It differs in hav- 
ing leaves which are rounded or truncate at the base and without a sinus. 
In addition, the middle lobe is 3-nerved and attenuate, not mucronate as 
in R. prestoniensis. 

In the collection cited above is a single pistillate specimen tangled with

the staminate shoots selected as the type. This pistillate specimen has 
the mature leaves elongate-ovate, with the basal lobes rounded or poorly 
defined. The size and venation are approximately the same as in the type 
specimen. The pistillate inflorescences are fascicled in the leaf-axils, 5-5 
being present per axil. The branches are racemose and 7-10 cm. long, 
although one or two measure 1°- cm. in length. The individual flowers 
are solitary on pedicels nearly 1 mm. long which bear a lanceolate bract 
near the base. The flowers are 1-1.5 mm. high, with a 6-parted perianth. 
The perianth-segments are ovate and average 0.5 mm. in length. There 
are 6 staminodes present in the flower and these are minute and bifid at the 
apex. The three styles are well developed and also bifid. The ovary is 
strongly 6-lobed. the alternate lobes being large and small. Dissection of 
the small lobes reveals the locules, which are almost lost in the mass of 
sterile tissue. One locule is usually larger than the others and the ovules 
in this appear turgid The other locules also have two superposed ovules 
but these are shrunken. Only a faint indication of a lateral gibbosity is 
developed in the specimen at hand; however, the condition of the ovules 
indicates that but one locule will develop and that the specimen is a true 
Raja nia. 

The young leaves are distinctly punctate-glandular, but the glands are 
fairly well masked in the mature lamina.

Wright's specimen bears an annotation. '■Rajania I'm, tins (Griseb.) Uline 
(let. nine." In Knuth's monograph of the Dioscoreaceae ( Pflanzenreich 
IV. 43: 168. 1924) this Wright number is divided. One pistillate portion 
is cited as Dioscorca linearis Griseb. and another pistillate specimen is 
referred to Rajania wit rop/iv/la Knuth. The species of Rajania, however. 
is typified by staminate material collected by Poeppig, and no description 
of the cited pistillate specimen is given. 1 have not seen the Poeppig 
specimen nor any fragments of the Wright material that could possibly be 
referred to the description of that staminate plant. 

The specimen of Wright 3254 at the Gray Herbarium consists of a shoot 
with a series of female flowers and young fruits attached. These are 
definitely Rajania fruits, having one carpel developed into a wing, with the 
stylar portions asymmetrically placed. On the same sheet are two infruc- 
tescences bearing fruits that are Dioscorca fruits and which have been 
annotated by Uline as D. tamoidca Griseb. These agree with the 
description given by Knuth for the fruits of D. linearis. 

The specimen selected by Knuth as the type of D. linearis was in the 



19171 HOWARD. MlMK I>1. WIS OF CUBA 119 

Berlin herbarium and is presumably destroyed. It seems necessary to 
conclude that his description of mature fruits of I), linearis was based on 
the unattached fragments of this Wright collection, which are fruits of 
D. tamoidea Griseb., as Uline noted. 

The pistillate inflorescence of Rajania linearis is short and bears few 
flowers. Mature inflorescences of the specimen on hand are 1-1.5 cm. 
long and bear 3-5 flowers, of which 2 or 3 mature on the average. The 
one-winged samaras are smaller than those of the majority of species, 
being about 4-5 nun. wide and S- 10 nun. long. A solitary small seed is 
developed.

Oriente: Sierra tie \ipe south of Woodfred, in dense woods, with yellow flowers, 
July 28-29, 1041, Howard 6134 (GH, type). 

Rajania tenella is similar to R. theresensis Uline and R. prestonicnsis 
Knuth, which I know only from the descriptions. It differs from R. 
prestonicnsis in the shape of the blade, the mature leaves being without 
sinuses and attenuate rather than mucronate. It is unlike R. theresensis 
in having the leaves 3-nerved, the inflorescence much shorter than the 



120 JOURNAL OF THE VRNOLD VRBORKT1M [vol. xxvm 

leaves, and the flowers smaller. It is easily distinguished from R. nipcnsis 
by the truncate base of the mature leaves. 

Considerable variation occurs between the juvenile leaves and the mature 
leaves in most species of Ra junta {Plate I/, //>. 2). For example, the 
juvenile leaves of the present species are elongate-ovate with the basal 
lobes more or less developed. The laminae are 2.5-3 cm. long and 0.3-1 
cm. wide. There are 3 primary veins, with the lateral veins arcuate. 
The apex is long attenuate and the base is truncate or rounded. The 
petioles are terete and from 0.6 1.2 cm. long. 

Because of this variation with age. care must be taken to collect and 
describe only mature specimens. Frequently the basal portion of a vine 
may be mature, but near the apex long axillary shoots, perhaps 4-9 feet 
long, may appear with only juvenile leaves. It is very easy to snatch 
immature material when such plants grow commonly in dense thickets.

Okiente: 20 km. west of Moa, in open pin, woods, in (lower and fruit, July 26, 
I'M I, Howard 5W1 (GH, type). 

Most of the plants of Platygync that I had seen growing in the central 
and western provinces of Cuba had been low shrubs, semi-scrambling over 
low bushes and in fence rows. It was quite a surprise, therefore, to find 
in the pine woods west of Moa ;i specimen of Platygyne climbing in the 
branches of the tall pine trees. The specimen also had distinctive obovate 
leaves with cuneate bases, short inflorescences, and the fruits were almost 
without the stinging hairs so common in the only other species of Platygyne 
recognized at present, P. hexandra (Jacq.) Muell. Arg. 

The indument in specimens of Platygyuc is of interest because of the 
several types of hairs found on different parts of the plant. Of most 
interest to the collector are the short white stinging hairs found only on the 
leaves, perianth, and on the mature fruits of /'. hexandra. This is quite 



1947] HOWARD, SOME PLANTS OF CUBA 121 

in contrast to the other common "ortiga" of Cuba, Tragia spp., in which 
stinging hairs are abundant on the stems as well as the leaves and inflores- 
cences. In Platygyne volubilis the stinging pubescence is found only 
on the upper surface of the leaves and along the margins as cilia. The 
hairs on the surface of the leaf are usually single, while the ciliate margin 
consists of clusters of hairs. The pistillate perianth also has a ciliate 
margin of stinging hairs, but this is lacking on the staminate perianth, 
finally, the fruits of P. hexandra are usually densely covered with the 
white pubescence of stinging hairs. In contrast the fruits of P. volubilis 
have only a few, if any, apical stinging hairs, and the rest of the capsule is 
covered with a very short ferrugineous indument. 

The pubescence on the rest of the plant, including the perianth, staminal 
disk, and styles, consists of ferrugineous short pointed stiff hairs, best 
described as strigose. 

The pistillate perianth is extremely variable. Baillon, Euphor. 453. 
1858, believed the perianth consisted of two whorls, while Mueller, in DC. 
Prodr. 15: 913. 1864, called them all calyx-segments of one whorl. The 
outer segments are usually linear-lanceolate and uniform. The inner 
segments vary greatly in size and shape and are frequently fused and 
3-4-lobed at the apex. 

The seeds are 3 mm. in diameter and almost spheroid. Mature seeds 
of P. volubilis are gray and are lightly mottled with a dark brown color. 
The seeds of P. hexandra in all the fruiting specimens I have seen are tan, 
mottled with dark brown. The seeds of Platygyne do not have an aril, 
although a linear protuberance or hilum is present for about one-third the 
circumference of the seed.

were in contrast with the red iron soil on which it was growing. On drying 
the leaves turn light green above and pale brown beneath. This species 
is distinct from others in the Orb'n idaria section of Phyllunthus by its large 
orbicular leaves, which are numerous for their size. The bright golden 
color and strongly revolwte margins of the leaves, the small stipules, and 
the short triangular bracts distinguish this species from others of the /'.

dull black, coarsely and deeply reticulated seeds of the present species are 
distinct from any 1 have seen in this genus, but so few seeds have been 
described that 1 can not evaluate this character.

The leaves of the present species are thick and coriaceous. The upper 
surface is shiny when dry and darker in color than the lower surface. 
Punctate glands are present in the lamina but are well hidden in the tissues 
of the leaf. Approximately <> strong lateral veins are revealed on the 
upper leaf-surface, and these anastomose near the margin. The veins 
are obscure below. 

Eugenia monnisis appears to be similar to E. ( .' j Ossacana I'rb.. which 
was described on very incomplete material collected by Shafer in the same 
locality as the present specimen. It is different in being completely 
glabrous, except for a ciliate perianth, and the venation of the leaves does 
not agree with the description as given by Urban. The pedicels of the 
present species are much longer than those of E. I') cupuVtgcra I'rb., to

O.ukxtk: Alone south coast of Baliia clc Moa near Moa, 4' shrub, fruits -rem 
becoming purple on maturity, Howard .^-}s (GH, type). 

Calyptranthcs obloHgijolia is characterized by the oblong or lanceolate- 
oblong leaves and the few-flowered, very short peduncles of the seemingly 
capitate, axillary inflorescence. In general appearance this species is 
similar to ('. rupkola Urb. and C. hctcrochroa Urb. 

The occurrence of malpighiaceous or two-armed hairs on the plant is 
characteristic of several species of Calyptranthes. In the present species 
these hairs are very dense on the young leaves, the stems, peduncles, 
flowers and fruits, giving the appearance of a ferrugineous tomentum. In 
the older leaves the hairs are broken off even with the epidermis and leave 
the sunken hair-bases commonly found in the other species and which 
frequently seem to be mistaken for epidermal glands. The upper surface 
of the mature leaves of C. oblongifolia is glabrous except for the impressed 
midrib, while the hairs on the lower surface persist. These hairs usually 
remain ferrugineous in color, although many turn gray or white. 

The inflorescence consists of short axillary peduncles with a very few 
flowers and appears to be capitate. The bracts subtending the flowers are 
minute and fall away very early, none appearing in the mature infruc- 
tescences. The flowers had matured on the specimens studied, but several 
young fruits still possessed 3 or 4 stamens attached to the hypanthium at 
the line of dehiscence of the calyptra. The style was 2 mm. long and 
bifid at the apex. The calyptra was conical and about 1.2 mm. in 

The drupes are a dark purple color when fresh, drying black or brown. 
Because of the dense pubescence, many appear to be silvery in reflected 
light. There are 2 cells to the ovary, each containing 2 seeds. The seeds 
are reniform and tan on the convex surface and black or dark brown on 
the sides and in the concave surface. The embryo is curved.

Psidium < onjertum is characterized by the small ovate to elliptic leaves, 
the persistent ferrugineous tomentum, the cymose inilorescence, and the 
2-celled ovary. In these characters il diners from /'. hidlatum Brit., P. 
ophiticola Brit, h Wils., and P. laophlovum Urb., to which it is related. 

The species is named for the crowded condition of the (lowering shoots. 
The internodes are from 1-1.5 cm. long with the leaves opposite or in 
whorls of three at the nodes. The compact inilorescence adds to the 
density of the shoots. 

The leaves are densely glandular; however, the glands are hidden by the 
persistent tomentum on the lower surface and are not visible from the 
dorsal surface. The very young leaves are densely pubescent on both 
surfaces. The lower surface remains persistently pubescent, while the 
upper surface is glabrous and becomes a bright yellow-green color on 
maturity. 

ids are globose above the 
and the numerous seeds 
are reniform. about 2 mm. long. On the concave surface of each seed 
extending over the sides arc' areas which are dark brown to black in color. 
The remaining surface of the seed is a yellow-brown. The embryo is only 
slightly curved.

This species at first glance is similar in appearance to E. psiloclada Urb. 
However, the leaves of the new species are coriaceous, the veins obscure, 
the upper surface shiny, and the margin strongly recurved. Eugenia

the characteristic glands, but these are buried in the leaf-tissue and are 
visible only when the leaf is held to the light. 

Several of the fruits examined had only one mature seed. Closer 
examination revealed an aborted cell and ovule at the apex of the fruit. 
The flowers are articulated to the pedicel, the fruits dehisce at this point 
very readily, and the peduncles persist even on the old shoots.

RELATIONSHIP AND TAXONOMY OF THE GEM S BRANDLSIA 

Hui-Lin Li 

The genus Brandisia is confined to the wanner parts of continental 
eastern Asia from eastern India. Burma, and Indo-China to southwestern 
and southern China. It has been included in the Scrophulariaceae, usually 
in the tribe Cheloneae, together with other anomalous genera like Paulownia 
and Wightia. Its taxonomic position has been doubted ever since it was 
first described, but no extensive and intensive studies have ever been made 
on the genus. 

The following study, based on the Chinese species of the genus, is made 
on materials assembled from various herbaria in America. To the curators 
of these herbaria I am indebted for their kindness in furnishing material 
for the study. This study was made at the Academy of Natural Sciences 
of Philadelphia during the tenure of a Harrison Fellowship for Research 
of the University of Pennsylvania. To Mr. Charles M. B. Cadwalader, 
President of the Academy. I wish to express my thanks lor permitting me 
access to the splendid library and herbarium facilities. To Dr. Francis 
W. Pennell, Curator of Plants, my thanks are due for his suggestions and 
his kindness in reading the manuscript.

RELATIONSHIP 

The tribe Cheloneae of the Scrophulariaceae is very artificial and 
heterogenous. To this tribe have been referred several of the woody 
genera of various localities, while the family Scrophulariaceae as a whole 
is herbaceous. The anomalous positions of Panlownia and Wightia have 
been questioned by some authors. Hallier (in Bull. Herb. Boiss. II. 
3: 181-207. 1903), in making a review of the taxonomic relationships of 
the various genera of the Scrophulariaceae, concluded that these two genera 
should be assigned to the Bignoniaceae. Campbell (in Bull. Torrey Bot. 
Club 57:47-50. 1930) reached the same conclusion for Paulownia. He 



128 JOI KWI. OK TIIK \KN01.1) MtHOK Kit \1 [vor.xxui. 

indicated that the small amount of endosperm present in the seed is not 
sufficient reason to exclude it from the Nignoniaceae. with which it agrees 
in many other characters. Ilallier. however, still considered Brandisia as 
belonging to the Cheloneae and evidently had not made any special study 
of the genus. 

When Hooker . •tn. 1 Thomson first described the genus no fruiting material 
was available. They noted the genera! appearance of the plant to be very 
different from the Scrophulariaceae. and rather verbenaceous. However, 
they placed it in the Scrophulariaceae because of the many-ovuled capsule. 
They remarked: 'The order can, in fact, only be approximately determined, 
as the dehiscence of the fruit and the stria hire ol (he seed are unknown. 
If the seeds be exalbuminous. it will go to Bignoniaceae; but the ovary 
and plaeentation are so much like Scrophulariaceae. that in all probability 
albumen will be found in the seeds." 

With regard to its position in the Scrophulariaceae. they said: "The 
position of Brandisia among Scrophularineae. as Mr. Bentham has kindly 
pointed out. is probably among Cheloneae. the only tribe in which large 
woody climbing plants occur. The tlowers though solitary, have two 
opposite bracteoles on the pedicel, and the curiously elongate ovules 
probably become winged seeds like those of Wig/i/ia." In the Genera 
Plantarum, the fruits and seeds were described and the genus was placed 
in the tribe Cheloneae together with Wight ia and Baulownia. This has 
been followed subsequently bv other authors. 

In 1873, Kurz (in Jour. As. Soc. Beng. 12(2): 39 141. 1874). in listing 
Brandisia discolor for the Burmese flora, considered the status of the genus 
and made the following statement: "Wightia, Walk, arete affmis. Ktiam 
Buddlciar generi affmis, sed differ! corolla irregulari. etc. et certissime inter 
Sesameas recipienda est. Cardneria, a el. Henthamio Loganiaceis adnu- 
merata, Solanea esse videtur." He placed the genus under "iVdalineae." 
In 1877 Kur/. (For. Id. Brit. Burma) listed Gclsrwium and Bndd/ria under 
"IVdalineae." in addition to Brandisia. Both these genera belong to the 
Loganiaceae. 

Hance (in Jour. Not. 18: 299. 1SS0) mentioned that Brandisia "has a 
curious resemblance to the genus Kremophila, in .Myoporaceae." This is 
an Australian genus. The Myoporaceae is a small family, with the genus 
Myoporum extending from the tropics of the Old World to India and 

Thus we have suggested relationship for the genus Brandisia to the 
following families: Loganiaceae, Solan, iceae. Scrophulariaceae, Bignoni- 
aceae. IVdaliaceae. Myoporaceae. and Yerbenaceae. 

Neing strongly /ygomorphic in its corolla. Brandisia cannot be associated 
with either Loganiaceae or Solanaceae. in which the. orolla is act inoinorphic. 
The place of the genus is evidently with the other families which have 
distinct zygomorphy. In spite of the general resemblance of the plant in 
appearance to some genera of the Myoporaceae and the Yerbenaceae, its 
many-ovuled ovaries and capsular fruits will not permit it to be included 



19471 LI, THE GENUS BRANDISIA 129 

in either of these two. Being a shrubby genus and without staminodes, 
it is not referable to the Pedaliaceae. 

The families Scrophulariaceae, Bignoniaceae, Gesneriaceae, and Oroban- 
chaceae are closely related and it is sometimes difficult to draw sharp 
distinctions between them. The Gesneriaceae and Orobanchaceao are 
predominantly herbaceous families, with unilocular ovaries, the latter being 
also parasitic. The choice for placing Brandisia is therefore left to the 
Scrophulariaceae and the Bignoniaceae. 

The Bignoniaceae are nearly all woody plants, many of them climbers. 
The Scrophulariaceae are predominantly herbaceous. The chief distinction 
between the two families is the presence of endosperm in the seeds in the 
Scrophulariaceae and the absence of the same in the Bignoniaceae. The 
fruit of the Scrophulariaceae is usually a capsule or sometimes a berry. 
The seeds are usually numerous and small. In the Bignoniaceae, the fruit 
is most often a two-valved capsule, usually very long and silique-like. The 
seeds are numerous, large, flattened, and membranaceous-winged. 

In the Scrophulariaceae, the tribe Cheloneae is one of the few that 
contains woody genera. In this tribe, which is artificial and ill-defined, 
there have been included some anomalous genera including Pauhncnia, 
Wightia, and Brandish!, Paulnwnia has been included in this family 
instead of the Bignoniaceae because of the presence of endosperm in the 
seeds. Hallier (1. c.) has shown that endosperm is only scantily present 
in Paulownia and is absent in II ightia, and that the seeds of both are 
winged. He concluded that both genera, in which all species are trees, 
should be transferred to the Bignoniaceae. 

The ovoid loculicidal capsular fruit of Brandisin is very similar to those 
of the Scrophulariaceae, but the seeds, although very small, are winged 
and are without endosperm. They are small, numerous, linear, with an 
elongated membranaceous winged testa which is reticulated. The fruit 
of Wightia is an oblong or ovoid capsule, but is septicidal, and the seeds 
are membranaceous and t 
is a woody capsule 

There is an apparent relationship between the three genera mentioned. 
The transference of Paulownia and Wightia to the Bignoniaceae, although 
they still appear somewhat anomalous in that family, seems to be a better 
arrangement than to have retained them in the Scrophulariaceae. 
Brandisia, although seeming even more isolated if placed in the Bignoni- 
aceae, certainly should be associated with Wightia, whatever the latter's 
disposition. Here we have a situation in which there must be additional 
knowledge in anatomy, pollen structure, cytology, etc., before a satisfactory 
disposition can be made of these genera as to their taxonomic position, as 
well as delimitation of the various families concerned. 

DISTRIBUTION 
To the eight species recognized in this study, there should be added 



130 JOl RNAF OF THE ARNOLD ARBORK'ITM [voi.xxvm 

three more from Annam, described by Bonati, of which no material is 
available. The genus ranges from Assam (India) and southern Burma to 
western China, north to western Hupeh, and southern China, east to 
Kwangtung. It is also found in Annam. Indo-China. So far it has not 
been recorded from Formosa, Hainan, or Tonkin. 

The species are found mostly on mountains up to an altitude of 3000 
meters, those in the south ascending usually to higher levels than those in 
the north. Most of the species are local in distribution and rare in 
occurrence. The most common and most widely distributed species is 
Brandisia Hancei, which is found in Yunnan, Szechuan. Hupeh. Kweichow, 
and Kwangsi. Brandisia rosea is found in northwestern Yunnan, Assam, 
and Bhutan. Brandisia discolor is found in southern Burma and southern 
Yunnan. Brandisia Swinglei occurs in Kwangtung and eastern Kwangsi. 
while B. hoan^siensis is known only from Kwangsi; the two species B. 
lactcvirens and B. ^labrcsccns are confined to southern Yunnan. Brandisia 
racemosa is found in Yunnan from the south to the northeast. Three 
species. B. Chcvalicri, B. annamitica, and B. scandens, are known from 
Annam only. 

The genus is primarily of the subtropical regions of eastern continental 
Asia, particularly of the mountains at medium levels. The center of 
distribution is apparently in Yunnan, where six of the eleven species occur. 
Only two, B. Hanoi and B. rosea, occur in the Sinn-Himalayan region in 
northwestern Yunnan, and these are not endemic. More species, although 
mostly of rather limited distribution, are found in the warmer regions of 
the province in the south as well as in the east.

LI, THE GEM S HliWPIMN 



With the addition of many other species to the original, it is necessary 
to redefine the generic concept of the genus and to form three subgenera, 
of which the last two contain each hut a single species. In addition to 
the eight species recognized for China. India, and Burma, there are three 
species described by Bonati from Annam. of which no material is available 
to me. Two of these, B. Chevalicri Bonati and B. scandcns Bonati, 
evidently belong to Rubra ndisia. Bmndisin unnamitica Bonati, described 
as having the flowers in groups of 3-5 and having two staminodes, may 
require the erection of another subgeneric group.

Yunnan. He said: "No good description of this species has been published 
so far, but according to Dr. A. B. Rendle of the British Museum who 
kindly compared Wilson's No. 3404 with the type of B. Hancei Hook. f. 
from Kweichou, there is no difference between the two specimens. Wilson's 
specimen also agrees perfectly with Henry's specimen from Hupeh referred 
by Hemsley to B. Hancei. Henry's No. 9013 from Yunnan differs slightly 
in its smaller and narrower leaves." IIu gave a detailed description for

(500-2600 meters) in the mountains of western China. It is readily 
distinguished from related species by its smaller, very compactly arranged 
leaves, which are nearly sessile and strongly cordate at base. The leaves 
are densely stellate-ferruginmis-tomentose on the lower surfaces and are 
not strongly discolored on the two surfaces as in some other species. The 
flowers (March-November) are red or yellow on the inside.

This species is a close relative of B. Hancei and B. discolor. It is dis- 
tinguished from the former by its large, less cordate, and more distinctly 
petiolate leaves. It differs from the latter notably in the larger calyx and 
shorter petioles. The corolla of B. discolor is also narrower and more 
densely tomentose and the leaves are darker on the upper surfaces, which 
become almost black in dried specimens.

Brandisia rosea is distinctly characterized by the bilobed calyx. In this 
respect, it deviates from the original generic limits. It also differs from 
other species in its general appearance, especially in the relatively narrow 
long-attenuate leaves which are sometimes oppositely arranged. In view 
of these differences, it is here segregated as representing a different 
subgenus. The fruit and seed characters are the same as in the other 

A varietv with vellow flowers was described by Fischer, from Assam, 
India, as Brandisia rosea W. W. Smith var. flava C. E. C. Fischer, in Kew 
Bull. 1934: 93. 1934. In the Genera Plantarum, it is stated that, besides 
the original B. discolor, there is another species in India. Hooker, in the 
Flora of British India, said: u The supposed second species of Brandisia, 
alluded to in the 'Genera Plantarum' as a native of Bhotan, has stellate 
tomentum, lanceolate leaves and a 2 -lipped calyx, and cannot be con- 
generic." Fischer identified this plant as belonging to B. rosea. He said: 
"Griffith's specimen [Kew Dist. 3748] from Bhutan, referred to in the Gen. 
PI. and in the Fl. Brit. Ind., and a sheet collected by Nuttall also in Bhutan 
(both in the Kew Herb.) are this species, but being in fruit only it cannot 
be determined whether they represent the typical species or the colour 
variety."

Oliver are distinctive. Two specimens collected by Hancock in the type locality in 
IS' 1 ' tre in the herbarium of the (Diversity of California. 

Brandisia racanosa is a most unique species of the genus, distinguished 
not only by the peculiar corolla-structure but also by the inflorescence. 
The tlowers are arranged in short or long racemes. The calyx is shortly 
and inconspicuously 5-dentate. The corolla is strongly bilobed, the upper 
lip being much longer than the lower. The lower lip'is 3-Iobed, with the 
two lateral lobes adnate to the sides of the upper lip midway in the corolla 
and the middle lobe attached much lower in a deep notch between the two 
lateral lobes. 

The plant also differs from other species of the genus in general appear- 
ance, with its long straggling branches and relatively smaller and more 
distinctly serrate leaves. The whole plant is blackened in the dried state, 
indicating its possible parasitic or semi-parasitic habit. Rehder mentioned 
that: "It was introduced by Mr. Wilson into cultivation, but it could not 
be. grown successfully, as it is apparently parasitic and its proper host 
plant is not known." 

Although the plant differs radically from other species of the genus in 
many respects, its basic characters in the stamens, fruits, and seeds agree 
with the genus in general. It is thought best to retain it in the genus but 
to designate a subgenus for its sole accommodation.

S\\. CIAKRIC HYBRIDS OF SORBIN 



THE CYTOGENETICS OF GENERIC HYBRIDS OF SORBUS 



With one plate 

The pomoideae constitute a group of rather closely related genera of 
common origin (Sax. 1933). All genera have a basic < hromosome number 
of 17 and generic hybrids arc relatively common. Natural hybridization 
is most frequent between Sorbus and the related genera Aronia, Amclan- 
chicr, and Pyrus. Rehder (1940, 1947) has described or enumerated 
seven hybrids between Sorbus and Aronia species, three hybrids of Sorbus 
and Amclanchier, and one hybrid between Sorbus and Pyrus. These genera 
are closely related and have been included in a single genus Pyrus by some 



The nomenclature in the fi lis is thai of Rehder (1940). 

The cytological analysis is based upon acetocarmine smear preparations, 
following fixation in alcohol-acetic acid. 

Hybrids between Sorbus and Aronia include Sorbaronia Jackii, S. 
Arsenii, S. hybrida, S. jallax, S. heterophylla, S. alpina, and S. Dippelii. 
Both the pinnate- and entire-leaved species of Sorbus have produced 
hybrids with Aronia speck s, all of which have entire leaves. Sorbaronia 
Dippelii has been crossed with Sorbus ahiiiolia in the Arnold Arboretum. 
Three of the Sorbaronia hybrids, 5. Jackii, S. alpina, and S. Dippelii, have 
been examined cytologically and attempts have been made to grow F 2 
generations. 

Sorbaronia Jackii is a naturally recurring hybrid between Sorbus ameri- 
cana and Aronia prunijolia. Specimens of the Sorbus parent in the 
Arboretum, both mature trees and 2-year old seedlings, have from 5 to 8 
pairs of leaflets with an average number of slightly less than 7. The F t 
hybrid has variable leaves, ranging from entire, as in Aronia. to pinnate 
leaves with as many as 3 pairs of leaflets in addition to the terminal 
leaflet. Often the leaves are partially pinnale or lobed. The average 
number of leaflets is 1.4. 

The open pollinated progeny of 5. Jackii are extremely variable in size 
and viability. Of 50 seedlings selected from the survivors grown in the 
greenhouse, seven have died in the nursery at the end of the second year, 
seven are extreme dwarfs, and 36 have made more or less normal growth. 
All surviving seedlings have at least partially pinnate leaves, ranging from 
3 to 7 leaflets with an average of 4.5. No segregates had any entire leaves. 
but these progeny may be back cross hybrids with adjacent pinnate-leaved 
species of Sorbus. Seedlings of Sorbus americana grown in the nursery 
showed much greater uniformity than those of the hybrid. Of 50 seed- 



138 JOURNAL OF THE ARNOLD ARBORETUM [vol. xxvm 

lilies, only one had died at the end of the second year. 

Sorbaronia Jackii produces abundant fruits, but much of the seed is 
defective or produces weak seedlings pollen sterility is variable, ranging 
from in sonic anthers to about 50 per cent in others. 

The meiotic divisions were generally irregular, but in some pollen mother 
cells the divisions appeared to be relatively normal. At first meiotic 
metaphase there were from 13 to 15 bivalents and from 4 to 8 univalents 
in most of the figures examined, although the number of univalents ranged 
from to 12. Lagging univalents were generally found at both first and 
second anaphase (lb.. I, fig. 1). The tetrads resulting from the two 
meiotic divisions were often irregular with some micronuclei. but as a rule 
nearly 50 per cent of the pollen appeared to lie morphologically normal. 

Sorbaronia alpina is a cross between Sorbus Aria, a species with simple 
leaves, and Arouia arbutijolia. This hybrid, as represented by the variety 
super-aria, is more sterile than Sorbaronia Jackii. Occasionally there 
appeared to be 17 bivalent chromosomes at the first meiotic metaphase, but 
the divisions were generally quite irregular, with as many as 14 lagging 
univalents at anaphase. For some anaphase figures the lagging chromo- 
somes appeared to include an occasional bivalent (Pl. I, fig. 2). The 
second meiotic divisions also were irregular and the pollen fertility ranged 
from to 24 per cent. For both of these Sorbaronia hybrids the pollen 
sterility varied greatly in different (lowers and some anthers contained no 
good pollen. Some fruits are produced by .S'. alpina, but we have not been 
able to germinate the seeds. 

Sorbaronia Dippelii is a hybrid between Sorbus Aria and Arouia mclano- 
carpa. This hybrid is relatively fertile, as indicated by both pollen 
sterility and by fruit development. Yet some anthers produce no good 
pollen and we have not been able to germinate open pollinated seed. 
Seventeen bivalent chromosomes were found at meiotic metaphase ( Pl. I, 
fig. 3), and there was little irregularity at meiotic anaphase. Pollen 
development was variable, but some counts showed as high as 58 per cent 
normal pollen. The pollen fertility oi the Arouia parent was only 76 per 
cent and that of the Sorbus parent about the same. 

We have succeeded in crossing Sorbaronia Dippelii with the distinct 
Sorbus species \. alnijolia. This hybrid has the characteristic foliage of 
N. alnijolia, the male parent. It is a slow growing shrub and has not yet 

Several hybrids between Sorbus and Amclanchicr have been described. 
The three known hybrids are growing in the Arnold Arboretum, but only 
Anic/asorbus Jackii is large enough to provide meiotic material. This 
hybrid was found among seedlings grown from seeds collected in the 
Moscow mountains of Idaho by Professor J. (i. Jack. It is described by 
Rehder as a hybrid between Sorbus scopulina and Amclanchicr jiorida. 
According to Professor Jack there were two types of the hybrid, one with 
partially pinnate leaves and one with only an occasional cleft or lobed leaf. 
Only the latter type is now available in our collections. 



1947] SAX & SAX, GENERIC HYBRIDS OF SORBUS 139 

Amelasorbus has been difficult to analyse cytologically. The microspore 
mother cells appear to disintegrate at any stage of development from 
prophase to microspores. In favorable prophase preparations 32-34 
chromosomes were counted at diakinesis, indicating a very loose association 
of paired chromosomes. At meiotic metaphase there were from 12 to 15 
bivalents and from 4 to 10 univalents (Pl. I, fig. 4). At anaphase the 
number of lagging univalents are variable, but as many as ten have been 
observed (Pl. I, fig. 5). Although the meiotic behavior of the chromo- 
somes of Amelasorbus is similar to that of two of the Sorbaronia hybrids, 
the sterility is much greater. Practically no normal pollen is formed and 
very little fruit is produced. Over a period of years only two viable seeds 
have been obtained and the resulting seedlings, which have now flowered 
for several years, are very similar to the parental hybrid in both appear- 
ance and sterility. Apparently they are of parthenogenetic origin. 

Two other forms of Amelasorbus are listed by Rehder (1947). Amela- 
sorbus Hoseri is thought to be a hybrid between Sorbus hxhrida and 
Amelanchier sp. It has partially pinnate leaves. Amelasorbus Racibor- 
skiana is listed as a cross between Sorbus sp, and Amelanchier asiatica. 
It too has partially pinnate leaves. Both of these hybrids were raised at 
the Kornik Botanical Garden in Poland and named by Wroblewski. Our 
specimens of these hybrids are not sufficiently mature lor meiotic analysis. 

The known crosses between Sorbus and Pyrus are limited to Sorbopyrus 
auricularis, a natural hybrid between 5. Aria and /'. ion/munis. We have 
in the Arnold Arboretum only the variety bulbiformis, a form which re- 
sembles Pyrus in most characters. This hybrid is a triploid with pre- 
sumably two sets of pear chromosomes. Its cytological behavior has been 
described earlier (Sax 1932). We have obtained some progeny from open 
pollinated seeds of Sorbopyrus. The seedlings are variable but tend to 
segregate into two groups — some which are vigorous and resemble the 
mother tree, and a series of dwarf segregates which survived for one to 
three years. 

In all of these generic hybrids involving Sorbus there is considerable 
sterility, and when segregates are obtained many are weak and do not 
survive. The genera Sorbus, Aronia, Amelanchier, and Pyrus can be 
crossed only in certain combinations. One might suppose that Aronia and 
Amelanchier could be crossed, since both have produced at least several 
hybrids with Sorbus, but repeated attempts to cross these genera have 
failed. However, we also have been unable to produce any artificial hy- 
brids between Aronia and Sorbus, and yet seven such spontaneous hybrids 
are known and some are recurrent in nature. 

The fact that Sorbus, Aronia, Amelanchier, and Pyrus can be crossed in 
certain combination indicates a certain degree of similarity. The behavior 
of the hybrids does indicate cytogenetic differentiation usually found in 
diverse species. Whether such incompatibility merits more than specific

SUMMARY 
Natural hybrids between Sorbiis and Aroiiia and between Amrhwchicr 
and Pyrus arc partially sterile and show considerable nieiotic irregularity. 
Sorbaronia produces a variable progeny both in morphological characters 
and viability. Amelasorbus produces iVw viable seeds and the progeny 
appear to be of parthenogenetic origin. Sorbopynts sets few seeds and the 
progeny include many dwarf segregates which survive for only a few 
years. The cytogenetic analysis indicates a common origin of these 
genera, but a degree of differentiation sufficient to maintain generic

A FIJIAN ACMom.K 



With one plate 

Among the collections of John W. Gillespie from the Fiji Islands is a 
single specimen (no. 3273, from Namosi Province, Viti Levu) which rep- 
resents a species of Acmopyle. This specimen had been included in a loan 
of material of Podocarpus from the herbarium of the Arnold Arboretum and 
had been inadvertently identified as Podocarpus vitiensis Seem. It differs 
in many important features, both externally and internally, from P. vitien- 
sis, and it agrees so generally in the anatomy of the leaves with Acmopyle 
Pilger that there can be no doubt about the generic identity. Specifically 
it differs somewhat I nun A< mnpyh Pan, furi (Brongn. & Gris) Pilger in 
several details, such as the external shape of the leaves and their texture, 
width, and apex. 

This is not the first report of Acmopyle in the Fiji Islands. Sahni (in 
Phil. Trans. Roy. Soc. London B, 210: 253-310. 1920), in his treatise 
on the structure and affinities of Acmopyle, mentions an earlier collection 
by J. Home in 1877-78, found in the herbarium of the Royal Botanic 
Gardens, Kew, which he examined in considerable detail. Sahni concluded 
that this specimen represents a species of Acmopyle. He also records the 
opinion of Dr. Stapf, who examined this material and who "does not con- 
sider it likely that the Fiji specimen is specifically identical with Acmopyle 
Pancheri, but he agrees to the generic identity." 

We have examined the leaves of the Gillespie specimen histologically, 
and also those of Acmopyle Pancheri, numerous specimens of Dacrydium 
jalcijorme (Pari.) Pilger, and some of Dacrydium taxoides Brongn. and 
Gris. Details given by Sahni concerning the flattening of the leaf in these 
species in the vertical plane, with the vascular bundle remaining in an un- 
changed orientation, can be substantiated in all essentials. The vascular 
bundles therefore appear as if turned sidewise through 90° with reference 
to the leaf surface. The above mentioned two species of Dacrydium, 
representing a special section of that genus, and the two species of 
Acmopyle share in this unusual type of leaf. Leaves of the Dacrydium 
spp. possess hypoderm and are bifacial, having palisade tissue and stomates 
on both sides, while the leaves of Acmopyle found on the pectinate twigs 
of the last order of branching have very little or no hypoderm, palisade 
tissue only on the upper side which is exposed to light, and the stomates 
confined almost entirely to the lower surface of the leaf. The unique 
type of leaf anatomy therefore serves to segregate Acmopyle from other 
genera of the Podocarpaceae.

koRTMAi.s in scriui:ii in his "(herzichl der Rubiaceen van de Neder- 
landsch-Oostindische Kolonien" (in Ned. Kruidk. Arch. 2 (2): 245. 1851) 
i.a. a new genus Streblosa, to which he referred Blume's Psychotria tortilis 
and two species based on specimens which he had collected himself in 
Sumatra and Borneo. Although he gave no explanation of the name, we 
may safely assume that it refers to the peculiar arrangement of the flowers 
along the branchlets of the inflorescence which they encircle in the same 
way in which the shoot of a winding plant twines round its support. 
Blume's epithet tortilis too was apparently inspired by the arrangement 
of the flowers. 

Korthals' generic description contains several inaccuracies; the calyx 
is not 5-dentate but 5-lid or. more rarely. 5-partite. the corolla-tube is not 
infundibuliform but cylindrical or, sometimes, in the upper half narrowly 
campanulate, and it is not glabrous inside but provided with a ring of 
hairs or with five hair-bundles, the aestivation of the lobes is not subvalvate 
but quite simply valvate, the ovules are neither peltate nor attached to 
the centre of the septum but ascending from the inner angle of the ovary- 
cells, the pyrenes are not plane on the inside but provided with two quite 
conspicuous contiguous excavations, and the embryo is not amphitropous 
but straight; the plants moreover are not fruticose but herbaceous, and 
their inflorescences are not axillary but at first terminal and subsequently 
pseudo-axillary. 

The generic description is followed by a note in which he gives an 
exposition of the reasons which induced him to separate this genus from 
Psychotria. It is reproduced here in English translation: ''On account of

their habit it seemed to me that the generic identity of the species here 
referred to Strcblosa with species belonging either to Psychotria or to 
Grit I already looked dubious, for they differ from them in their 
membranous, reticulately veined leaves and in the peculiar corymbose 
inflorescence. The analysis of the flower revealed, in addition to a number 
of identical features, in the structure of the ovary a diagnostic character 
of sufficient importance: whereas in Psychotria the ovules arise from the 
bottom ui the cells, they are in Strcblosa attached to the centre of the 
septum and peltate." The argument derived from the position of the 
ovules, by which Korthals apparently set great store, and which he thought 
would justify the creation of the new genus before the tribunal of his 
fellow botanists, unfortunately was based on inaccurate observation: in 
reality the ovules of Strcblosa arise just like those of the other l'sychotrieae 
from the inner angle of the ovary-cells. 

Miquel already had some doubts with regard to Korthals' description 
of the position of'the ovules. In his "Mora Indiae Batavae'' (2: 2o4. 1SS7) 
he reduced the genus to a subdivision of Psychotria for which he retained 
the name Strcblosa and which he characterized with the aid of the data 
provided by Korthals. An interrogation mark, however, is put behind 
the words with which the attachment of the ovules to the middle oi the 
septum is described. Afterwards Miguel's valuation of the distinguishing 
characters underwent a change, for in his "Fxloge Rubiacearuni Archipelagi 
Indici" (in Ann. Mus. Hot. Lugd.-Bat. 4:211. 1S69) the genus is 
reestablished. As no generic description is given, and as no comment is 
made on this change of attitude, it is impossible to say how the latter was 
brought about. It is noteworthy that Mi<|iiel corrected in this work 
Korthals' assertion with regard to the habit of Str. torli/is (HI.) Khs: he 
himself describes it as an herbaceous plant. Of the two new species 
described by Korthals only one, the Sumatran Str. polyantha, was found 
by Miquel in the Leiden herbarium (I.e. 262): it seems that the specimen 
on which the other species, the Bornean Str. iindu/a/a, was based, had 
disappeared already, and the type of Str. tortilis var. p. collected by 
Korthals on G. Singalang in West Sumatra, which is said to differ from 
the form described by Blume in its sessile inflorescences and elliptic leaves, 
was not met with either: in contradistinction with Sir. undulata (v. infra) 
it has never again been mentioned in literature. It may have have been 
conspecilic with one of the Sumatran species dealt with below, but nothing 
definite can be said with regard to its identity. 

Hooker f. reduced Strcblosa in Benth. et Hook. f.. ('.en. PI. 2: 124. 125. 
1N7.V to Psychotria: as tin- author attached great importance to the 
position of the ovules, it is unlikely that he would have made this reduction 
if he had not convinced himself of the inaccuracy of Korthals' description. 
The type-species was referred by Hooker to the section Mapouria (a 
ebracteatae). where it occupies on account of the persistent bifid stipules, 
the cincinnate arrangement of the dowers, the small green fruits and the 
two contiguous excavations on the ventral side of the pvrenes, a most

anomalous position. Korthals' other species are not mentioned, but a 
plant collected in Penang and in the Wallich herbarium, inserted under 
the provisional name Psychotria microcarpa Wall., is declared conspecific 
with Ps. tort Ms Bl., an error which was repeated by King and Gamble in 
their 'Materials for a Flora of the Malay Peninsula" (in Jour. As. Soc. 
Beng. 72 (2): 11. 1906) and by Ridley in his short survey of the genus 
Strcblosa in Jour. As. Soc. Straits 57: 62. 1911. It was corrected by the 
latter in his "Flora of the Malay Peninsula" (2: 148. 1923). 

Baillon referred Strcblosa in Adansonia 12:325. 1879 and in his 
"Histoire des Plantes" (7:285. 1880) to Uragoga L., which in his 
delimitation is an even more unwieldy genus than Psychotria L. in that 
of Hooker, and it is therefore not necessary to discuss this reduction. It 
is noteworthy, however, that he corrected Korthals" assertion with regard 
to the aestivation of the corolla-lobes. Writing of Sir. tortilis he stated in 
Adansonia: "Sur les echantillons que nous avons pu examiner, toutes les 
corolles etaient simplement valvaires." 

Schumann made no mention of the genu- Strcblosa in his monograph of 
the family in Nat. Ptlanzenfam. 4:4. 1891; and in the "Nachtriige" to 
this work too I have vainly looked for any reference to it. In Dalla Torre 
& Harms. Genera Siphonogamarum. 503, 1905, however, it is included 
among the synonyms of Psychotria. 

Stapf was, after Miquel. the first to recognize the generic distinctness 
of Korthals' genus. In his paper on the flora of Mt. Kinabalu (in Trans. 
Linn. Soc. Bat., II. 4: 182. 1894) he described a new species. Str. urtkina. 
and expressed himself with regard to its generic position in the following 
terms: "I think Strcblosa should be kept up as a distinct genus on account 
of its peculiar habit, which is produced chiefly by the herbaceous growth, 
by the very thin leaves, the axillary inflorescences (which in the present 
species resemble very much those of a common nettle), and by the minute 
flowers and fruits. Miquel says of Strcblosa Trutices'; but the specimens 
of S. tortilis (Bl.) Korth., the only species seen by him. are decidedly 
herbs. The genus Strcblosa is limited to Malaya." The statement that 
the inflorescences are axillary, is incorrect: in reality they are terminal 
but soon pushed aside by an axillary branch developing in the axil of one 
of the two highest leaves. The reference to Miquel is incomplete: in the 
'•Flora Indiae Batavae" the latter merely repeated Korthals' statement, 
but in his paper in the "Annales" he described Str. tortilis correctly as 
"herba basi radicans." 

The next author who recognized Strcblosa as a distinct genus, was 
Valeton. In Bot. Jahrb. 44: 568. 1910, he described a new species, Str. 
glabra, based on a specimen collected by Winkler ( Breslau ) in South-east 
Borneo; it appears very close to Str. urtkina Stapf. At the same time he 
gave a more detailed description of Str. undulata Khs.. based on some other 
specimens collected by Winkler in the same region as Str. glabra and as 
Korthals' type. Whether these specimens really are conspecific with the 
latter, is difficult to say, because of Korthals' incomplete description, but 



148 .101 KNAL OF TI1K ARNOLD ARBORETUM [vol. xxviii 

it should be noted that the leaves are elliptic according to Korthals, 
whereas Valeton states that they are 90-120-150 mm. X 35-50 mm., 
which means that they arc lanceolate in his specimens. However, as 
there is little chance that Korthals' type will ever be recovered, and as 
there is otherwise nothing in his description which positively excludes the 
possibility that his type was conspeciuc with the specimens described by 
Valeton. the latter's interpretation may perhaps be accepted. 

At about the same time Ridley (in Jour. As. Soc. Straits 57: 62. 1911) 
devoted a few pages to Strcblosa. He agreed with Stapf that the genus 
should be restored, bul no new arguments were brought forward to support 
this view. He recognized seven species, i.e. apart from the three for which 
the genus was created and the one described by Stapf. three new ones. Of 
these three the first, Str. hirta, is probably identical with Str. polyantha 
Khs., of which Ridley had seen no material. The only difference which I 
can find in comparing Korthals' specimens with Ridley's description, lies 
in the slightly narrower leaves ( 10-15 cm. X 3.7-5.0 cm. instead of ( > 12 
cm. X 4.5-5.7 cm.). In the description of Str. pubescens Ridl. there are 
a few points which make the position of this species altogether dubious: 
the stipules are said to be lanceolate-acuminate, whereas in this genus they 
are always two-lobed ; the stamens should be inserted near the base of the 
tube instead of in the ring of hairs in the middle or somewhat above the 
middle, the stamens as well as the style should be included, whereas Ihe 
flowers of Strcblosa are always heterostylous with either the stamens or 
the style exserted. and the disc is .aid to be composed of 5 renjform bodies. 
whereas I found it in Strcblosa always semi-globose or annular with a 
single, more or less distinct, transverse impression on the top. For the 
time being, therefore, 1 consider Str. pubescens a "species incertae sedis." 
The third species, Str. bractcata, on the other hand, is a true representative 
of the genus, probably nearly related to the plan! afterwards described 
by Merrill under the name Str. in vriot arpa. hike the latter it is found in 
West Borneo. Ridley remarked with regard to Str. urticina Stapf that 
he saw in the herbarium of the botanic (iardens, Singapore, a specimen 
collected by Haviland and bearing the number of the type, which was 
"decidedly woody," whereas Stapf described it as 'herbaceous and 
scandent." Ridley was right in so far that the plant is certainly no 
(limber, and that it is woody at the base: as secondary thickening, how- 
ever, is by no means uncommon in the basal parts of the stems of 
dicotyledonous herbs, this is no valuable argument .mains! its herbaceous 
character. 

In the following year Elmer (Leatl. I'hilipp. Hot. 4: 1356. 1912) 
published some remarks on a plant which he had collected in the island 
Palawan, and which he referred to Str. glabra Val. It differs, however, 
conspicuously from the latter by the nature of the stipules, whose lobes 
are separated from each other by a rather wide gap instead of being 
contiguous. His remarks contain several mistakes: the valvate corolla- 
lobes are described as imbricate and slightly twisted from left to right; 



1947J BREMEKAMP, THE GENUS STREBLOSA 149 

the stamens are said to be inserted in the basal part of the corolla-tube, 
and the anthers should be more or less united, the stigma "submitraform," 
the ovary "superior or nearly so, surrounded by 5 lobular disk append- 
ages," and the ovules should be pendulous. That the genus is said to be 
monotypic and previously known from Borneo only, may be regarded as a 
slip of the pen. 

In the same year Valeton (in Icones Bogorienses 4: 139, t. 343. 1912) 
published a detailed description of Str. tort ilk (Bl.) Khs.. accompanied by 
a plate which unfortunately is not entirely satisfactory. His ideas on the 
generic characters are summarized in the following sentence: "Le port 
de la plante, les inflorescences axillaires, Tinsertion scorpioide des fleurs 
sur les rameaux (voir la figure 2 dans la table citee de Stapf) et la structure 
du fruit sont autant de caracteres de valeur generique et qui separent la 
Streblosa du genre Psychotria:' Valeton therefore was the first to 
recognize the taxonomic importance of the monochasial structure shown 
by the ultimate ramifications of the inflorescence, and although he calls 
the latter here for sake of convenience axillary, the remarks in his paper 
in Bot. Jahrb. 44: 568. 1910, show that he knew very well that they are in 
reality at first terminal and afterwards pseudo-axillary. 

A few years later Merrill (in Philipp. Jour. Sci. Bot. 10: 141. 1915) 
described under the name Str. axitti flora, a new species from the Philippines. 
In a short note attached to the description he remarks: "I am in agree- 
ment with Valeton and with Ridley in considering Streblosa Korthals to 
be a valid genus. In aspect the plants are entirely different from 
Psychotria and Grumilea, and the differential characters appear to be 
constant. From all our representatives of Psychotria and Grumilea the 
present species is distinguished by its minute fruits and axillary inflores- 
cences; surely, if Grumilea is to be separated from Psychotria, there are 
as great or greater reasons for distinguishing Streblosa as a valid genus." 
Merrill afterwards (Enum. Philipp. Fl. PL 3:564. 1923) identified the 
Philippine species with Str. glabra Val., but this was an error: it differs 
from the Bornean species in the same way as the plant collected by Elmer 
in Palawan, the stipular lobes namely are not contiguous but separated 
from each other by a rather wide gap. and the internodes are ecostate. 

Since then one new species was described from the .Malay Peninsula by 
Ridley and eight from Sumatra and Borneo by Merrill. With regard to 
our knowledge of the generic characters however, no further progress was 
made. In this paper a detailed analysis of the generic characters is given. 
Twenty-five species are described, and an attempt is made to arrange them 
in a more or less natural sequence. Pleven of the twenty-live species are 
new, whereas three of the old ones, namely Str. hirta Ridl., Str. platyphylla 
Merr. and Str. puberula Merr. are reduced to synonymy, and one. Str. 
pubescens Ridl., set apart as a "species incertae sedis." Of Str. urticina 
Stapf and of Str. palawanensis Brem. two varieties are recognized, and of 
Str. axilliflora Merr. three.

The stems are either erect or. more often, ascending, and there is doubt- 
less a certain amount of vegetative propagation, young plants developing 
sometimes from the axils of the fallen leaves in the decumbent and rooting 
basal part. Even in those species that are provided with erect stems, for 
instance in Str. Johamiis-Winkieri Mere, in which this kind of growth is 
perhaps most pronounced. I have sometimes found remains of old shoots 
at the base of the young ones. T suppose that in these plants the whole 
stem sinks down after the last fruits have ripened, and that here too new 
stems develop from axillary buds. That these innovations are but rarely 
met with in herbarium specimen-, probably means that they are not 
regularly formed. In some of the species with ascending stems, especially 
in those in which the leaves do not show much difference in shape and 
size, e.g. in Str. tortilis (Bl.) Khs. and in Str. bullata Merr., development 
might even be continuous, the oldest part of the stem gradually decaying 
and the bent at the same time shifting in the direction of the younger 
parts: in such species innovations are perhaps formed only when the 
normal development in some way or other is checked. 

Ramification is extremely rare: so far it has been observed in three 
species only, in Str. lampongensis Brem., Str. chl.inivtlautha Brem. and 
Str. loii^israpa brem. It is always brought about in the same way, namely 
by the development of two axillary shoots instead of one at the base of 
an inflorescence. This is rather interesting from a morphological point of 
view, for it definitely proves the terminal nature of the inflorescence: 
without the evidence of the forked plants the latter would always remain 
somewhat dubious, for the terminal position of the young inflorescence 
might be spurious, and the presence of but one inflorescence at each node 
is in itself no sufficient proof. 

In habit the Stnblosa species therefore are not unlike those belonging 
to the genus Notoplvura Brem. (Psychotria L. sect. Xoto pleura Hook f. in 
Benth. & Hook, f.. Gen. PL 2: 124. 1873, cf. Brem. in Kec. d. trav. hot. 
Need. 31: 289. 1934), for the species of that genus too are herbaceous and 



l5 2 JOl KNAF OF TI1F AKNOFI) UiBOKFTFM I vol. xxviii 

provided with usually simple, sympodial stems, the terminal inflorescence 
being pushed aside by an axillary shoot developing from the axil of one 
of the leaves at its base. In other respects, however, there are important 
differences. In Xotoplatra the leaves are succulent, the stipules undivided, 
the inflorescences paniculate or corymbose, the flowers ebracteate, the 
corolla-lobes imbricate, and the pyrenes dorsivent rally compressed and on 
the inner side flat or provided with a prominent keel; the genus, moreover. 
is confined to Tropical America. The affinity between Strcbhsa and 
Xoto pleura, therefore, must be regarded as rather remote. 

Although the stems probably do not last for more than a few months, 
there is often a considerable amount of secondary thickening in their basal 
parts. As a rule the increase is almost entirely due to the formation of 
secondary xylem, but in the species described below under the numbers 
1-11, there is also a considerable development of secondary bast. The 
formation of cork is. as a rule, but weak, and in most species the stem, 
therefore, remains green. 

As in most of the plants belonging to the undergrowth of the forest, the 
leaves are. as a rule, large, flat, thin and discolorous. In the majority of 
the species belonging to the subgenus l.ii-streblosa (Sir. tortilis, Str. 
myriocarpa, Str. maxima, Str. Johannis-Winkleri, Str. bullata, Str. brae- 
tcolata, Str. anamhasu a, Str. potvan/ha, and to some extent in Str. ddiensis 
and ,S7/\ scabridida) the underside of the leaves is covered with greyish 
scales, which under the microscope prove to be dome-shaped excrescences 
crowned by a stoma, an arrangement which apparently is not uncommon 
in shade plants. Taxonomically of more importance is the structure of 
the epidermis on the upper side. As in I'sy< hotria the latter consists of 
straight-walled cells, but in the midst of these some much smaller ones are 
found which are produced above the common surface into lenticular or 
conical excrescences (fig. 1). The latter are often difficult to detect with 
the naked eye. but appear to he present in all species. In the other genera 
of the 1'sychotrieae I have looked, so far. in vain for them. Far more 
conspicuous are the reddish or blai k dots with which the upper side of the 
leaves of .S7/\ tortilis, Str. miennarpa, Str. polvantha, and probably those 
of Str. multi^landiilosa, which I could not investigate myself, are marked. 
These dots are caused by the presence of a dark-coloured resin in some of 
the epidermis cells. As a rule they are in these species a very conspicuous 
feature, but as a differential character they are of little value, for their 
development varies considerably, even in leaves of the same specimen; in 
some instances the cells contain little or no resin, and as the cells themselves 
are indistinguishable from the rest of the epidermis cells in shape and size, 
microscopical investigation too is in such cases of no avail. Of Str. tortilis 
and Str. mitromrpa I have seen specimens in which the dots appeared to 
be completely absent. 

Resin may also be present in some of the cells of the mesophyll and in 
the mesocarp of the fruit, and even in other parts of the plant, for instance 
in the cortex and in the secondary bast of the shoots; in the latter these

cells are arranged in short longitudinal rows. Their number varies con- 
siderably, and they are not always easy to detect, but it is almost certain 
that they are nowhere completely absent. One of the most suitable places 
to look for them, is the connective. In the species 1-6 they are a con- 
spicuous feature of the secondary bast. When they are present in the 
mesophyll, the leaves are, as a rule, more or less distinctly marbled. It 
is noteworthy that such marbled leaves occur also in some related plants, 
e.g. in the Madagascar species of Psychotria. 

Raphide-cells are in some species a conspicuous feature, whereas in 
others they are difficult to detect. This depends apparently on the 
consistency of the leaves, for microscopical investigation reveals that they 
are nowhere absent. As a matter of lad. they are a general feature of 
the whole tribe, and are also found in some of the latter's allies, for instance 
in the Hedyotideae, whereas they are constantly absent in the Ixoreae and 
their allies, which, as I have pointed out in my -'Monograph of the genus 




i.-,4 joi i;\ \i ok nil', \k\oi n \i;i;oi;ih m h«u.. xxvm 

I'avclia" (in Fedde's Report. 37: 11. 12. 1934), form another circle of 

The nervation of the leaves is very uniform; the meshes formed by the 
lateral nerves and the venules are large and more or less irregular in 
outline. Aearidomatia are always absent. 

Tin' stipules are always interpet iolar and produced into two lobes, but 
they vary considerably in size and shape. In the species belonging to the 
subgenus Eu-strchlosa they are much larger than in the subgenus Para- 
streblosa, and in the first-named subgenus the basal part is stronger 
dexcloped than the lobes, whereas in the species belonging to the latter 
the lobes are better developed than the basal part; in Eu-strrMosa they 
are moreover more or less persistently filiate or ciliolate. whereas in 
I'dm-stri'Mosti they are eciliate. In part of the species belonging to the 
latter the basal part shows a prominent midrib which runs down to the 
preceding node. In these species, which form the series Costatac, the 
lobes are moreover contiguous, whereas in the two other species, which 
are brought together in the series Ecostatar, the midrib is invisible and the 
int. 'modes accordingly ecostate. and the lobes are separated from each 
other by a wide gap. Costate stipules are found also in some of the 
species belonging to the subgenus En-stn hlosa, but only in one of them. 
Sir. JohaiDns-Winkhri Mere, the rib runs down along the stem. In the 
other species all the nerves arise from the angles of the stipule and converge 
towards the top of tin 1 undivided part, where they enter the lobes. As in 
many other genera belonging to this family, a fairly large number of 
colleters is found in the axils of the stipules. They are in this genus 
rather large. 

The inflorescences are always of terminal origin, but by the development 
of a branch from the axil of one of the leaves at their base, they are, as 
stated above, soon pushed aside. They are, as a rule, shortly pedunculate, 
but in Str. tortUis the peduncle is about as long as the petiole of the leaf 
at its base, and in Str. longisaipu it is even about as long as the whole leaf. 
In these two species the peduncles are moreover erect, whereas they are 
in the other species of the subgenus Eu-strchlosa recurved, and in those 
belonging to Para-streblosa patent. 

The inflorescences themselves show various degrees of complexity. The 
simplest form is that found in Sir. hractcolata Merr.: it consists of a 
single axis bearing at each node a sterile brail and a pair of flowers, one 
provided with a bract and the other ebracteate. The ebracteate flower 
might be regarded as a superposed one. and the whole inflorescence as a 
raceme, but it seems more plausible to regard the ebracteate flower as a 
terminal one. and the bracteate flower as representing one of the branchlets 
of a dichasium, the other branchlet forming the continuation of the axis 
(fig. 2). This interpretation is supported by two weighty arguments: 
( 1 ) the ultimate ramifications of the inflorescences of the Psychotrieae 
are everywhere of the dichasial typo, and there is therefore every reason 
to assume that those of Strchlosa will be ni the same or at least of a 



19171 BREMEKAMP, THE ('.KM S STREBLOSA 155 

related kind; (2) in almost all the other species of Stirhlosa the branchlets 
are at least partly arranged in pairs with a single tlower in the fork between 
them, which means that Ihey themselves are parts of a dichasinm, and 
it is a well-known fart that the branchlets of a dichasium often develop 



into monochasia. whereas the 
dichasia developing into raceme

In Str. bullata Merr. the inllorescence is twice dichasially branched i

the branchlets develop in the same way as the inflorescence of Str. 
bracteolata. 

In the other species we find three or five subumbellately or, rarely, 
racemosely arranged branchlets, of which the lowest pair are sometimes in 
their turn provided with a pair of lateral branchlets; the main branchlets 
as well as those of the second order may be once dichasially ramified, but 
the prongs of these dichasia, or the branchlets themselves if they are 
unforked, are monochasial. 

The monochasial structure of at least a part of the inflorescence, is a 
character of great taxonomic importance, for this arrangement is found 
nowhere else in the I'sychotrieae. 

It is in cymous inllorescences always somewhat difficult to make out 
how the terms bract, bracteole and pedicel should be used, but if we stick 
to the principle that the bud in the axil of a bracteole remains rudimentary, 
we may find a way mil of the difficulty, lor in this case the only hypsophylls 
to which the name could be applied, would be the ultimate ones in whose 
axils the flowers remain rudimentary, but as these hypsophylls are indubi- 
tably homologous with the other ones, there is obviously no reason to give 
them another name: in the cymous inflorescences there are therefore no 
bracteoles. When this is conceded, the determination of what should be 
called pedicel, offers no difficulty: in a dichasium it is obviously the axis 
which begins at the insertion of the dichasial prongs or at the insertion of 
the bracts in whose axils the latter develop. In a monochasium the base 
of the pedicel is accordingly recognizable at the insertion of the bract or 
of the bract-pair. In Strcblosa the matter is somewhat complicated by 
the circumstance that the two bracts which one would expect to find at 
tin- same height, are in reality often inserted at different heights. This 
means that between the two of them an extra internode has developed, 
which we will call the interbracteal internode. The shoot which forms 
the continuation of the axis of the monochasium develops always from the 
lower bract, which, as a rule, is somewhat larger than the other one, in 
whose axil the lateral tlower develops. In the subgenus Eu-strcblosa the 
interbracteal internode is always easily recognizable, whereas in J'ara- 
strcblosa it is either absent or indistinct. In Para-streblosa the flowers, 
moreover, are always Mil»c»ilc. whereas in /•.'// strcblosa subsessile flowers 
are met with in .S7/\ tortilis and in Str. microcarpa only; in the other 
species they are distinctly pedicellate. Because of the presence of the 
interbracteate internode the flower-pairs of /•.'// strcblosa give one the 
impression of being stipitate. and for the sake of convenience, this term 
has been used in the descriptions of the various species. 

The flowers are always 5-merous and heterostylous. It is true that 
those of ,S7/\ urtichia were described by Stapf as 4-merous, but this is a 
mistake: in the drawings on the plate accompanying his description they 
are correctly shown as 5-merous. They are as a rule very small. The 
largest ones which I could investigate, are those of Str. bracteolata. which 
reach a length of 9 mm.; in several other species they vary between 2.5 



19471 BREMEKA\H\ Tl IK (,KM S STREBLOSA 1S7 

and 3.5 mm. Heterostyly is very often met with in the I'sychotrieae and 
their allies; it occurs, for instance, also in the Hedyotideae. It is. 
however, no general feature of these tribes. The ovary is always bilocular 
and, as everywhere else in the I'sychotrieae. each cell contains a single 
ovule ascending from the angle between the bottom of the cell and the 

The calyx consists of a short lube and live usually short, broadly 
triangular, ovate-triangular or suborbi. ulai . rarely somewhat longer and 
then oblong, lobes, alternating with baculiform glands. The latter are 
like the previously mentioned raphides and the tendency to heterostyly 
a general feature of the I'sychotrieae and of some of the related tribes, 
e.g. of the Hedyotideae. The aestivation of the calyx-lobes is usually 
more or less open or subvalvate; the large calyx-lobes of Str. chlamydantha 
Brem.. however, are distinctly imbricate. 

The corolla is always white, and consists of a short cylindrical or, in 
the upper half, above the insertion of the stamens, slightly widened tube 
and five spreading lobes, valvate in the bud. In the middle or somewhat 
above the middle the tube is provided with fairly long hairs. In 
Eu-strchlosa the latter form a complete ring, whereas in l'ara-strcblosa 
they are arranged in five bundles alternating with the stamens. 

The stamens are inserted at the same height as the hairs. In the 
long-styled flower they are more or less included, and in the short-styled 
one exserted. The filaments are always glabrous, and the anthers oblong 
and dorsifixed. The pollen grains are small, globose. 3-porous and 
minutely reticulated. 

The disk is. as a rule, fairly large, semi-globose or annular, and glabrous. 
At the top it shows a transverse impression corresponding in position with 
the septum in the ovary. 

The style is thin and glabrous, and ends in two filiform or narrowly 
linear stigma-lobes. In the short-styled flower it is included, and the 
stigma-lobes are but slightly spreading, whereas in the long-styled flower 
it is exserted, and the stigma lobes are more distinctly spreading and at 
the top sometimes recurved. 

The fruits are very small, smaller, in fact, than anywhere else in this 
tribe, and in size and shape more like those of Ilrdyotis, Lrrchca or 
Xanthophytum than like the drupes of the other I'sychotrieae. They 
are either globose or, more often, didymous, crowned by the persistent 
calyx and the somewhat shrunken disk, and they remain always green. 
When fully ripe, they split into two drupaceous mericarps. which in the 
herbarium are distinctly costate, but in the fresh condition smooth. The 
mesocarp is but weakly developed, and the endocarp too is thin. The 
pyrenes vary in colour between yellowish, red and almost black, and t hex- 
are usually 5-ribbed, three of the ribs ornamenting the convex side, and 
the two others marking the border of the latter; the flat inner side shows 
in the centre an excavation, which a more or less distinct keel divides into 
two parallel or upwards somewhat divergent hollows. The keels may be 



158 ,)0l li\ \I. OF Till'. \K\()1.I) \KBOKFTl \1 I vol.. xxvm 

acute or obtuse, and the excavation on the tlal side varies in the various 
species somewhat in size and shape, but the differences are difficult to 
describe, and they are therefore not mentioned in the descriptions. The 
seed shows exactly the same sculpture as the pyrene, and consists of a thin, 
red or red-dotted testa and a uniform horny endosperm. The embryo is 
small and nearly straight, and the radicle points downwards. 

'I'he shape and sculpture of the pyrene. and the way in which the testa 
surrounds and eventually penetrates the endosperm, are important diag- 
nostics for the genera belonging to the Psyrhotria group. Strrblosa is for 
instance easily distinguishable from Maponr/a Aubl., to which the type- 
species was referred by Hooker in IJenth. & Hook, f.. Gen. PI., by the 
presence of the two contiguous hollows on the ventral side of the pyrene. 
and from Psvrhotria I., in the delimitation in which it is taken by me (cf. 
Brem. in Jour. Bot. 71: 273. Oct. 1933, and in I'ulles "Flora of Suriname" 
4: 261. 1934) by the absence of the median groove on the ventral side of 
the pyrene and the corresponding intrusion of the testa into the seed. 
Apart from the difference in si/e. the pyrenes of Strrblosa, however, are 
very similar to those of Grophila Don; the fruits of the latter, on the other 
hand, are not only larger but also more fleshy, and coloured instead of 
green. The pyrenes of Xotoplrura, the genus which resembles Strrblosa 
in habit, are dorsiventrally compressed, and their ventral side is either 
entirely Hat or provided with a protruding ridge, but the latter does not 
arise from the bottom of a cavity. Of these plants too the fruits are 
coloured and larger and more fleshy than those of Strrblosa. 

Within the genus Strrblosa itself two slightly different kinds of fruit 
are met with. In the subgenus Eu-strrblosa and in ,S7/\ ciilamydautha 
and Sir. longisrapa the mericarps are nearly globose, and the fruits there- 
fore didymous. but in the other species of Para-streblosa the mericarps 
are semi-globose, and the fruits accordingly globose: in herbarium material 
the latter are S-ribbed. whereas the dubmous fruits are either o- or 
10-ribbed. In the species which are normally provided with didymous 
fruits, occasionally some globose ones are found; the latter are 5-ribbed 
and owe their aberrant shape to the abortion of one of the mericarps. 

CLASSIFICATION OF Till- SPFOIFS 1 
The genus has here been divided into two subgenera. In Eu-strrblosa 
the stipules are wider than the stem, and their basal part is more strongly 
developed than the lobes, the flower-pairs are distinctly stipitate, i.e. the 
interbracteate inteniode is always developed, the hairs in the corolla-tube 
form a complete ring, and the fruits are always didymous. In Para- 
strrblosa, on the contrary, the stipules are not wider than the stem, and 
their lobes are better developed than the basal part, the flower-pairs are

19471 BREMEKAMP, THE GENUS 

subsessile, i.e. the interbracteate internode is either absent or but indis- 
tinctly developed, the hairs in the corolla-tube are arranged in five bundles, 
and the fruits are usually globose; didymous fruits, however, are found 
in Str. chlamydantha and in Str. longiscapa. 

A further subdivision of En-sfnblosa does not lead to results which are 
of practical value, the groups becoming too small. The first two species, 
Str. tort His (Bl.) Khs. and Str. microcnrpa Ridley with their subsessile 
flowers, are doubtless nearly related, but Str. lampongcnsis Brem., a 
species with distinctly pedicellate flowers, shows in the structure of its 
stipules with their comparatively long lobes, an unmistakable likeness with 
these two species. The next three species. Str. bract rata Ridl., Str. 
myriocarpa Merr. and Str. maxima Brem., form another natural group, 
characterized by large leaves and very large, oblong or obovate stipules. 
Ovate or ovate-lanceolate stipules provided with a prominulous or promi- 
nent midrib characterize a group of Bornean species, to wit Str. Johannis- 
Winklcri Merr.. Str. bulla t a Merr. and Str. bract colata Merr., to which 
the less known species Str. mnltiglandidosa Merr. and Str. undulata Khs. 
interpr. Val. probably also belong. A somewhat isolated position is 
occupied by Str. anambasica Brem.; in the small size of the (lowers it 
resembles the Sumatran species which form the next group, but it differs 
conspicuously from this group by the more strongly ramified inflorescences. 
The five Sumatran species, Str. dcticnsis Brem.. Str. kypomalaca Brem.. 
Str. Iciophvlla Brem.. Str. polyantha Khs. and Str. scahridula Brem.. are 
provided with ecostale stipules, and possess inflorescences with three 
undivided branchlets and very small flowers. 

In Para-strcblosa two series may be distinguished: the Costatac with 
conspicuously cost ate stipules and bicostate internodes. and the Ecostatac 
with ecostate stipules and smooth internodes; in the first series the stipular 
lobes are contiguous, whereas in the second they are separated from each 
other by a wide gap. The first are confined to Borneo, whereas the 
second group is found in Palawan and other islands of the Philippines. 
The latter comprises at present but two species, one consisting of two, and 
the other of three varieties, but it is not impossible that further study will 
show that these varieties are sufficiently distinct to be regarded as species. 
Among the Costatac, Str. chlamydantha Brem. and Str. longiscapa Brem. 
occupy a more or less isolated position. They are provided with didymous 
fruits" and their calyx-lobes are larger than in the other species.

Sumatra: Galangankwo near GinteriL', Korthah s.n. (I.): leave, m.iih-wIi.h 

The exact locality of the plant collected by Korthals in Sumatra, is 
unknown to me: that quoted above, is the one given by Korthals in his 
paper in Ned. Kruidk. Arch. 2 (2): 246. but a label attached to the 
specimen in the Leiden herbarium and written by Korthals himself, is 
inscribed: P. Genting. 

A specimen collected by Koorders in Hanjumas (Central Java), has 
leaves which are much larger than those of the type (up to 14.5 cm. X 
9 cm.), and are not dotted with resin cells, but are like those of the type 
provided with 8 or 9 pairs of nerves. The position of this specimen is 
somewhat uncertain: provisionally I refer it to the species described above. 
but more material from the same region will have to be investigated before 
a definite conclusion can be drawn. Koorders-Schuhmacher I.e. quotes 
a specimen (Koorders 23565 BZ) collected in the Making Resiliency at 
Sumber Tangkil. Tt remains to be seen whether this really is conspecific. 

In some of the specimens, e.g. in Blume 893, anomalous inflorescences 
are seen in which the branchlets are replaced by somewhat impoverished, 
but otherwise normal inflorescences. 

The roots on the decumbent part of the stem are not confined to the 
nodes, but spread over the whole length of the internodes. S< filthier 2700 
shows young plants springing from the decumbent part : one of them is 
already rooting at the base. 

Streblosa tortilis comes very near to Sir. mkrocarpa, with which it was 
confused by Hooker ll.ee. In the shape of the stipules and in the structure 
of the inflorescence with its live forked branchlets and subsessile flowers 
and in the usually conspicuously dotted upper side of the leaves there is 
a close resemblance, but .S7;\ tortilis is a much smaller plant, the stem

rarely exceeding 20 cm. in height and the leave- rarely 10 cm. in length; 
the leaves, moreover, are ovate or ovate-elliptic and acute or subacute 
instead of elliptic and more or less distinctly acuminate, and they are 
lepidote on the lower side, and the peduncle is erect and about as long as 
the petiole of the leaf at its base, instead of much shorter and recurved. 
With Str. lamponu,t usis too it shows an unmistakable affinity, for instance 
in the shape of the stipules and in the development of a rather thick 
secondary bast streaked with red resin cells in the basal part of the stem, 
but this specie- ha- distinctly pedicellate (lowers and its leaves are not 
dotted with resin cells on the upper side. Groups of resin cells in the 
secondary bast are not confined to these three species, but are found also 
in Str. myriocarpa and in ,S7/\ maxima, and perhaps in the related species 
Str. bractcata and Str. mitlti^lamlulosa, but of these I had no material at 
my disposition, and the original descriptions make no mention of this 
character. An epidermis dotted with resin cells on the upper side of the 
leaves, is a much less common feature than the presence of resin cells in 
the cortex and in the secondary bast. In this respect Str. tortilis is 
matched only by Str. mit rocarpa and probably by Str. multi'jlandnlosa , 
and further by the but distantly related Str. polyantha. These resin 
cells are not always easily distinguishable, probably because the production 
of resin varies according to circumstances, and as the cells, in which the 
resin is deposited, are in shape and si/e indistinguishable from the ordinary 
epidermis cells, it is easily conceivable that they are not always conspicuous.

King & Gamble I.e., cite under their Psychotria tortilis a specimen 
collected in South Sumatra by Forbes (1495), which I have not seen, and 
whose position, therefore, remains uncertain: it may have belonged to the 
real Strcblosa tortilis or to Str. lampongensis. 

Merrill, I.e., rejected Ridley's name for this species because the specific 
epithet was adopted from Psychotria wienxarpa Wall., which he regards 
as an illegitimate name because there exists an earlier homonym. In 
reality, however, it is a manuscript name, which means that it is to be 
regarded as non-existent. As the plant, therefore, had no legitimate name, 
Ridley was free to choose whatever name he wished. 

The differences between Str. microairpa and Str. tortilis have been given 
above. In general aspect it is perhaps more like Str. lampongensis, which 
it resembles in height and in the shape and size of the leaves, but from 
which it is easily distinguishable by the subsessile flowers.

It is n-.t impossible that Forbes I-W5, which was collected in the same 
region, will prove to belong to this species. As stated above, it was 
referred by King ov Camble to their I'syehntria tortilis. 

A noteworthy feature of the specimens described above is that they are 
partly pseudo-dichotomously forked. This means that in this species 
occasionally both the axillary buds at the base of the peduncle develop 
into a shoot. The same phenomenon has been observed in Sir. ehlamy- 
tlaiitha and in Sir. lnn«iseapa. 

Streblosa lanipnn^eiisis resembles the two preceding species in the shape 
of the stipules, the thick layer of secondary bast and the five main 
branchlets of the inflorescence, but it differs conspicuously from them in 
its distinctly pedicellate flowers. In this respect it resembles the following 
species, in which the pedicels, however, are much longer and the bracts 
much larger, and whose stipules are provided with a larger undivided part 
and shorter, not diverging lobes.

The description given above has been adapted from the original. 
Ridley ascribes to the midrib of the leaves and to the peduncle a "scurfy" 
pubescence, which, as scales are unknown in this genus. I have interpreted 
as a pubescence caused by curled hairs. This is in accordance with what 
in other species is found. On account of the large oblong stipules and the 
numerous lateral nerves I have placed it in the neighbourhood of Str. 
myriocarpa, from which it should be easily distinguishable by the glabrous 
stem, the nearly glabrous leaves, and glabrous stipules and by the somewhat 
longer peduncle. Unfortunately no material was available to me for

provided with stout, densely pubescent shoots, large, on the upper side 
completely glabrous and on the underside. espe< ially on the midrib and on

leaves, large, slightly puberulous pubescent stipule- and many-flowered

bractcaia is apparently a less robust plant provided with a less conspicuous 
indumentum, but with leaves and stipules of a similar shape and size. 
Sfnb/osa maxima differs from Sir. myriocarpa m the greater length of the 
petioles, the larger, caudate-acuminate leaves with their smaller number 
of nerves and more lax reticulation, the reddish brown colour of the

The position of this species is difficult to determine. The presence of 
resin cells not only in the mesophyll of the bracts and in the mesocarp but 
also in the epidermis on the upper side of the leaves is a diagnostic 
character of great importance, but as these cells are found in such distantly 
related species as 5/r. tortUis and Str. polyantha, the taxonomic value of 
this character is small. Of more importance are the ovate stipules, the 
long iloral bracts and the pedicellate flowers, for on account of these 
characters it is to be assigned a place between or next to the species 9-18, 
of which the first four occur, like Str. nudti^aiididosa, in Borneo and the 
remaining ones in the Anambas Islands and in Sumatra. The presence 
of curled hairs on the stem and on the underside of the leaves suggest a 
nearer affinity with the Bornean Str. bullata and Str. bractcolata. On 
account of this presumed affinity it has been assumed in the key that it 
belongs to the same group of bornean species as the latter (species 8-11), 
and that its stipules are, like those of the other species of this group, 
provided with a prominent midrib. It differs from the species 8-11 in the 
presence of resin cells in the epidermis on the upper side of the leaves. 
In this respect it resembles the Sumatran Str. polyantha. from which it 
is easily distinguishable by the entirely glabrous upper side of the leaves. 
In the "rather rigid" leaves it resembles Str. bractcolata.

The stipules of this species are not only like those of Str. maxima, Str. 
hullata and Str. braitcolata, provided with a distinct midrib, but its inter- 
nodes, moreover, are distinctly bicostatc, the midribs of the stipules 
detuning to the preceding node, whereas the shoots of the other species 
are ecostate. bicostatc internodes, however, are a constant feature of the 
Bornean representatives of the subgenus Para-strcblosa. Among the 
species belonging to the subgenus h'.u-strcblosa. to which Str. Johannis- 
Wink/rri. on account of the ovate stipules, unequal floral bracts and the 
complete ring of hairs in the corolla-tube doubtless belongs, it comes nearest 
to ,S7r. undulata, Sir. bulbil a and Str. brat i -obit a. which it resembles in the 
shape and si/e of the stipules and in the nature of the indumentum. From 
.S7r. bullata and Str. braitco/ata it differs conspicuously in the narrow 
leaves, and from Str. undulata in the smaller number of nerves; from all 
three moreover in the bieostate internodes.

with those collected by Korthals on Mt. Sakumbang, seems dubious, for 
Korthals described the leaves as elliptic and hirsute on the nerves beneath, 
the stipules as ovate and the bracts as oblong, whereas the leaves of 
Winkler's specimens are, according to Valeton's description, lanceolate 
and sparsely villosulous on the nerves beneath, the stipules ovate-lanceolate 
and the bracts linear. It is quite possible that in the future, when the 
flora of the south-eastern part of Borneo becomes better known, a species 
may be found which fits Korthals' description better than that described 
by Valeton. In my opinion it would have been belter if Valeton had 
described Winkler's specimens under a new name: in the absence of the 
type-specimen, Korthals' species doubtless can not be regarded as 
sufficiently recognizable. Provisionally, however, I have accepted Valeton's 
interpretation. 

The species described above apparently comes near to Str. Johannis- 
W'mklcri, from which it differ- in a somewhat more conspicuous indumen- 
tum, a larger number of nerves in the leaves, narrower stipules, and 
probably also by the absence of the ribs on the internodes: the latter, at 
any rate, are not mentioned in Valeton's description.

Its most important character, however, is the twice dichasially branched 
inflorescence. In this respect it conies nearest to Str. bract colata, for in 
both species the inflorescences are entirely e\ annus, whereas elsewhere the 
main axis bears a number of racemosely at ranged branehlets. In the 
length of the bracts and in the comparatively large si/.e of the flowers too. 
these two species resemble each other. In the nature of the stipules and 
in the hairiness of the nerves and venules on the underside of the leaves 
they resemble the other bornean speeies of the subgenus Eu-strcblosa.

As stated above, this species tomes nearest to Str. hullata, from which 
it is. however, easily distinguishable: its leave- are plane, the inflorescences 
unbranched, the bracts longer and the flowers larger. The relations of 
these two species with .S7r. Johannis W'hiklcri and .S7; . umhtlata have been 
discussed alreadv in the note at the end of the description of .S7/\ Johamiis- 
Winkleri. 

Merrill, I.e., compares this species with Str. pubescens Ridl.. of which I 
have seen no material, but whose position in the genus Strcblosa seems to 
me very dubious. Its stipules are said to be lanceolate-acuminate, which 
would mean that they are entire, its stamens should be inserted at the 
base of the corolla-tube, and both the stamens and the style should be 
included. It is possible thai my objections against its position are based 
on inaccuracies in the description, and that it is in reality a true Strcblosa. 
On account of its stibsessile flowers, it is, at any rate, not probable that it 
would belong to the nearest allies of the species described above.

This species occupies a rather isolated position in the genus. By the 
shortness of the pedicels it resembles Str. lampongcnsis, from which it 
differs, however, conspicuously in the shape of the stipules and in the 
thinness of the secondary bast. In the shape of the stipules it resembles 
the Bornean species 8-11 and the Sumatran species 13-17, especially the 
latter, for from the Bornean species it differs by the inevidence of the 
midrib. The Sumatran species it resembles also in the thinness of the 
secondary bast, but it differs from them in the larger number of branchlets 
in the inflorescence. 

Habitually Str, anambaska is easily distinguishable from the other 
species of the subgenus Eu-streblosu by its glabrous leaves. The only 
other species with entirely glabrous leaves is Str. Iciophylla, a plant from 
the Mentawei Islands, which is provided with much smaller, more compact 
inflorescences with three simple branchlets, larger stipules with shorter 
lobes, and nitidulous, in dried material olivaceous leaves.

in the basal part of the stem, the ecostate stipules, and the very shortly 
pedunculate inflorescences with their three simple branchlets, which do 
not markedly elongate when the fruits ripen. They are all five endemic 
in Sumatra and the neighbouring Mentawei Islands. Stnhlosa drlirnsis 
differs from the four others in the narrower, bifid, not bilobate. stipules 
and in the ovate shape of the bracts at the base of the inflorescence. It 
is a nearly glabrous plant, and in this respect it comes nearest to Str.

It can therefore hardly be doubted that they are identical with the latter. 

The stipules of Str. hypomalaca are of the same shape as those of Str. 
leiophylla, Str. polyantha and Str. scabridula, but they are much smaller. 
A remarkable feature of this species is the comparatively short petioles:

This species is easily recognizable by the completely glabrous stem and 
leaves. In the size of the stipules it resembles Str. polyantha and Str. 
scabridula, but in other respects it is more like Str. hypomalaca, the other 
species from the Mentawei Islands; its leaves are like those of the latter, 
on the underside smooth, not lepidote as in Str. polyantha and Str. scabri- 
dula, i.e. they lack the pallid protuberances by which in the latter the 
stomata are raised above the general level of the epidermis, and the flower- 
pairs are provided with a stipe of the same length as that of Str.

The leaves of Str. hirta Ridl. have been described as slightly narrower 
than those of Str. polyantha (10-15 cm. X 3.7 5 cm. instead of 9-12 cm. 
X 4.5-5.7 cm.), but as the description reveal- no other points of difference, 
I am, for the moment, unwilling to accept it as specifically distinct. 
Ridley had seen no material of Korthals' species, and the existing descrip- 
tions were too incomplete to be of much use It is. of course, not 
impossible that a renewed investigation will reveal the presence of more 
important differences. 

Strvblosa polyantha resembles the next species in many respects, but is 
easily distinguishable by the softness of the indumentum, by the somewhat 
broader leaves, which are provided with a smaller number of nerves and 
with resin cells in the epidermis of the upper side, and further, by the 
black pyrenes.

Strcblosa chlamydantha and .S7r. lon^iscapa, both inhabitants of the

reach a height of about one meter. 'Fhey are. moreover, not rarely pseudo- 
dichotomously branched, but this peculiarity has also been observed in 
Str. lampon^cHsis. From the other species of Para-streblosa they differ 
conspicuously in the didymous fruits. Strcblosa chlamydantha, moreover. 
is easily recognizable by the large size of the bracts and by the large,

Strcblosa lanceolata, Str. urticina, Sir. glabra and Str. assimilis resemble 
each other in the globose fruits, the short calyx-lobes and the shortly 
pedunculate inflorescences. Strcblosa lanceolata and Sir. wticina resemble 
each other also in other respects, for instance in the shape and size of the 
leaves and in the ronspieuousness of the raphides on the underside, and 
also in the early deciduous bracts. The leaves of Str. lanceolata, however, 
are slightly narrower and shorter petiolate. The peduncles of this species 
too, are distinctly shorter. The leaves of Str. glabra and Str. assimilis are 
much wider, and the raphides are invisible; their bracts persist for a longer

The G. Labang, where this specimen was collected, lies near the British- 
North- Bornean frontier. 

Streblosa urticina and .S7>\ lanccolata are doubtless closely related. As 
stated above, the leaves of Str. urtkhia are slightly wider and longer 
petiolate. and the peduncles arc much longer. Streblosa urticina, more- 
over, appears to be a plant occurring at a higher altitude: the specimens 
of the var. Stop fit at least were all collected between 1000 and 1500 m., 
whereas Str. lanccolata was found at a height of 90 m. Streblosa urticina, 
Str. mkrocarpa and Str. axiili flora are the only species found above 1000 
m. altitude, but the two latter have also been collected in localities less high.

Babi H Winkler 2751 (L, dupl. typi). British North Borneo: Elphinstone 
Prow, Tawao, Elmer 21140 (U, AA. exempla tvpi Str. platy phylla Mm.). 

The name of this species is somewhat misleading, for it is by no means 
completely glabrous. It may have influenced Merrill when he investigated 
the plants collected by Elmer at Tawao. Merrill described the leaves of 
the latter as "praesertim ad costam nervosque plus minusve sordide 
villosis," and a detached leaf added to one of the specimens in the her- 
barium of the Arnold Arboretum, indeed answers this description, but this 
leaf, which differs from the others not only in the nature of the indumentum 
but also in the colour it assumed in the press, and in the conspicuousness 
of the raphides, is either teratologics! or. more probably, part of another 
species. It is possible that the type-specimen consists of stems provided 
with this kind of leaves, but in view of the fact that the rest of the 
descripion agrees with that given above, this seems less probable than the 
supposition that the tvpe too consists of leaves of both kinds. Acting on 
this supposition, I have reduced Str. platy phylla to Str. glabra. Whether 
the aberrant leaf belongs to a Streblosa species, is, of course, difficult to 
decide, but in view of the great similarity in the nervation, this does not 
look improbable to me. 

Streblosa glabra differs from the two preceding species in the greater 
width of the leaves and in the inconspit uotisness of the raphides, and also 
in the subpersistent stipules and bracts. From the next species it differs 
in the smaller size of the leaves, which, moreover, are provided with a 
smaller number of nerves, and in the smaller size of the flowers. The 
internodes of Str. glabra are less distinctly bicostate than those of the 
other species belonging to this series, but the ribs are nevertheless plainly

Very similar to the preceding spe< ies and by Valeton regarded as a mere 
variety of the latter (Sir. glabra Yal. var. brevipes Yal. in sched.), but 
differing in several points: the stem is glabrous, more strongly bicostate 
and more robust, the leaves are larger, provided with a larger number of 
nerves and almost completely glabrous, the peduncle is shorter and the 
flowers are nearly twice as large. 

It is not impossible that Ridley 12430 from Puak and 12432 from 
Lundu in Sarawak. whi< h Ridley referred to ,S7/\ intieina, but of which he 
says: -'They are more robust with larger leaves, the stems quite woody 
and erect," may prove to belong to the species described above.

Elmer, I.e., describes the leaves of this plant as nitiduloiis. but in dried

been pointed out in the introduction to this paper. 

Streblosa paliruwirnsis resembles Sir. axil/iflora in the ecostate inter- 
nodes and in the wide gap between the two stipular lobes, but differs from 
that species in the absence of grooves in the young internodes, in the size 
and shape of the stipular lobes and in the shape of the gap by which the 
latter are separated from each other, and also in the somewhat larger size 
of the flowers.

Pomazota Ridl. was based on a planl collected in the Malay Peninsula. 
The valvate aestivation of its eorolla lobes, the dehiscent fruit and numer- 
ous angular and alveolate seeds prove that it belongs to the Hedyotideae. 
Ridley's plant shows a striking resemblance to the species of the genus 
Coptophyllum khs., but Ridley was of opinion that H differs from them in 
the nature of its fruits. Those of Pomazota are stated to open by a lid. 
whereas those of Coptophyllum are assumed to be indehiscenl . Ridley's 
idea of the fruits of the latter, however, was apparently based on a some- 
what superficial study of the literature. It is true that both in Rentham 
& Hooker's "(ienera Plantarum" and in Schumann's monograph of the 
family in Fngler & Prantl's "NaUirliche Ptlanzenfamilien" the genus is 
reckoned to the M ussaendeae. i.e. to a tribe in which the fruits are said to 
be indehiscent. but korthals himself had been less positive, for he had 
described the fruit (in Ned. Kruidk. Arch. 2 (2): 161. 1851) as "capsula 
membranacea indehiscens (?) bilocularis." Thai the interrogation mark 
in this sentence belongs to "indehiscens" and not to "bilocularis" need not 
be doubted. Whether the septum of a bilocular ovary persists or disap- 
pears in the ripening fruit is taxonomically, as a rule, but of little 
importance, and if Korthals had fell the slightest uiu erlainty on this point, 
he certainly would have preferred to pass on without mentioning the 
number of fruit-cells. Moreover, Hentham & Hooker, as well as 
Schumann, and Ridley also, had apparently overlooked Miguel's descrip- 
tion of Coptophxllum' c a pit at urn ( PI. Ind. Hat. 2: .*4S. 1S57), the species 
quoted by Ridley in his "Flora of the Malay Peninsula." for Miquel 
described the fruits- of this plant as "capsulae vertice apertae." 

As the fruits of ('. pilosum, the second species described by Miquel (in 
Ann. Mus. Hot. Lugd.-Hat. 4: 2S0. I860), open in the same way as those 
of C. capitation, and as up to now no further species of this genus have 
been made known, we may safely conclude that the difference in the 
nature of the fruits on which Ridley had based his generic distinction, is 
in reality non-existent. Moreover, as the real differences existing between 
the species of Coptop//yltnm and Pomazota are all found to be of minor 
importance, it is clear that the two genera must be considered identical. 

A difficult}' to the view here brought forward lies in the fact that 



1947J BREMEKAMP, THE GENUS POMAZOTA 187 

Korthals' generic description deviates in two points from that given below, 
the corolla being described as naked inside and the calyx-lobes as oblong. 
Another objection might be found in the obtuse stipules mentioned in the 
description of the type-species, but these incongruities should not be 
taken too seriously. The oblong calyx-lobes offer no difficulty at all, for 
calyx-lobes of this shape really occur in some of the species, but as they 
can not be considered a general feature of the genus, they could, of course, 
find no place in my description. A corolla naked inside and obtuse 
stipules, however, occur in none of the species below referred to Pomazota, 
and their presence in the type-species of Coptophyllum, therefore, would 
form a serious obstacle to my view of the identity of the two genera. This 
obstacle can only be overcome by assuming that the observations of 
Korthals were incorrect. Mistakes of this kind may easily come about 
when the material is incomplete and in a bad condition. The ring of 
spreading hairs in the upper part of the corolla-tube, although a very 
striking feature in the fully developed flower, is easily overlooked when 
the flowers are still in bud. for these hairs are at first firmly pressed against 
the wall. The sharp points of the stipules may pass unnoticed, because 
they are easily broken off: it is quite conceivable that they may have been 
absent in Korthals' specimens. As the latter are lost, the question of 
their generic position can not be settled with absolute certainty, but as the 
rest of Korthals' description agrees well with that given below, e.g., in 
the very characteristic shape of the stigmata, and as we know no other 
genus which fits the description equally well, there is apparently no reason 
to regard Coptophyllum as a "genus clubium" or to doubt its identity with 
Pomazota. However, as the name Coptophyllum Khs. (in Ned. Kruidk. 
Arch. 2 (2): 161. 1851) is a later homonvm of Coptophyllum Gardner (in 
Hook., Ic. PI. 5: t. 477, 478. 1842), it can not be retained, and is to be 
replaced by Pomazota Ridl. (in Trans. Linn. Soc. Bot. II 3: 308. 1893). 

When an older generic name is rejected in favour of a more recent one, 
the question arises as to which species should be regarded as the type. It 
can obviously be solved in either of two ways, for our choice depends on 
what we consider more important: the connection will) the name which is 
to be retained or that with the taxonomic conception which found its first 
expression in the rejected name. The '-International Rules of Botanical 
Nomenclature" give us no guidance. It is true that Art. 5 says: "In the 
absence of a relevant rule or where the consequences of rules are doubtful, 
established custom must be followed," but as the type-method is still 
comparatively young, one can in this case hardly speak of '-established 
custom." On an earlier occasion (in Jour. Arnold Arb. 21:34. 1940), 
when the type of the genus Urophyllum Wall, had to be fixed, I chose the 
second alternative, because it appeared to me that the taxonomic concep- 
tion should be considered more important that a mere name. As type of 
the genus Urophyllum Wall. I therefore chose U. arboreum (Reinw. ex 
Bl.) Khs. This species namely is the type of the genus Wallichia Reinw. 
ex BL, and Wallichia Reinw. ex Bl. is the name under which 



188 JOl'RNAL OF THK AHNOI.I) UJKOlllTl \1 [vol. xxvm 

conception now known as I'rophyllum Wall, was first put forward. If the 
same rule is to he applied in the present case, the type will have to he 
looked for among the species originally referred to Coptophyllum Khs. 
This, however, offers a new difficulty. 

The genus Coptophyllum Khs. was based on a plant collected on Alt. 
Singalang in Western Sumatra. It was described binder the name ('. 
bractcatum Khs. Under ordinary < ircumstances this species, of course, 
should he regarded as the type, but unfortunately its identity is not fully 
certain. As stated above, the specimens on which il was based are lost. 
and the description is not sufficiently detailed to allow its identification. 
Apart from its occurrence in the Uplands of I'adang. there are but two 
points in the description which might give us a clue: the oblong calyx-lobes 
and the presence of stiff hairs on the upper side of the leaves. More or 
less oblong calyx-lobes are found in I'omazota assimilis Brem. n. spec., a 
near ally of Coptophyllum capitatum Miq., and also in Pomazota rivularis 
Hend. and the nearly related /'. scabiosiflora Brem. n. spec, and /'. 
batuvnsis Brem. n. spec. The two last-named species need not be taken 
into consideration, for in /'. scabiosiflora the leaves are glabrous on the 
upper side and /'. batuvnsis has not yet been found outside the Batu 
Islands. Pomazota assimilis and /'. rivularis lit Korthals' description 
almost equally well, and as both are known to occur in the mountains of 
Sumatra, it is impossible to make a choice: moreover, Korthals' species 
may have been different from both. Therefore, as Coptophyllum bract la- 
tum Khs. can not be identified with certainty, it can not he accepted as 
the type of the genus, and we will have to fix our choice on the species 
which conies next in age. This is C. capitatum Miq. Miquel was 
apparently at first not fully convinced that this species belonged to 
Coptophyllum Khs.. for in the original description he put an interrogation 
mark behind the generic name, but this was dropped in his paper on the 
Kubiaceae of the Malay Archipelago in Ann. AIus. Hot. Lugd.-Bat. 
I: 1869. 

It is a rather curious coincidence that the genus had also drawn Blume's 
attention. Among the unclassified Kubiaceae of the Utrecht Herbarium 
I found a specimen of I'omazota pi/osa (Miq.) Brem. n. tomb. {Copto- 
phyllum pilosum Miq.) which had been collected by Kiihl and van Hasselt 
at the Tji Djralang in S. \Y. Bantam. The collectors, who regarded it as 
an Argostcma, had provided it with a short diagnosis, but the really 
interesting point of the specimen is that it also bore a label in Blume's 
handwriting with the name "Lasiagatkis humilis Bl." The genus 
Lasiagathis, however, has never been published. 



the tribes Hedyotideae, 



1947] BREMEKAMP, THE GEM S POMAZOTA 1H9 

as they are called by Schumann, and Mussaendeae. which rests merely on 
the dehiscence or indehiscence of the fruits, can not he kept up. "if the 
two tribes, Hedyotideae and Mussaendeae," I wrote. I.e., "are united, the 
bulk of the genera at present included in them, form a natural group, 
characterized not only by the pluri-ovular ovary cells and the valvate 
aestivation of the corolla lobes, but also by the axile or nearly axile, 
peltate or subpeltate placentation and by the ovoid or angular, yellowish, 
reddish or brown, more or less distinctly alveolate, striate or punctate 
seeds. Genera in which some of these characters are wanting, for instance 
those with a clavate or columnar placenta and smooth seeds, should be 
excluded." With these misplaced genera I reckon, among others, 
Schradera Vahl, the twin genera Coccocypselum [P. Br.] Sw. and 
Lipostoma D. Don. "I'ammsia Karst., which probably belongs to another 
family, Carphalea Juss.. Dirkhlrtia Klot/sch. Placopoda Baill., Payera 
BailL Jtukia Wall.. Cntikshankia Hook, and the two genera Carlemannia 
Benth. and Sylvianthus Hook. f.. which do not belong to the Rubiaceae 
but should find a place in the vicinity of the ( 'aprifoliaceae. 

Among the genera which are left in the tribe two smaller groups have 
already been recognized. One comprises / 'roph v/Iiim \\ all. and the nearly 
allied genera Anthcrostclt Brem.. Pidymopo^oii Brem.. \I aschalocorymhus 
Brem., Pravinaria Brem. . Praravinia khs., Rhuphidura Brem., Lcucoloph us 
Brem., Lrpidostoma Brem.. VU'nx nrphiia K.Sch. and Stirhiaiithus Yah, 
characterized by the axillary position of the inflorescences, dioecious 
flowers, a pluri-locular ovary, paired, at first nearly axile placentas, which, 
when the fruit begins to swell, shift towards the middle of the radiating 
septa, stamens or staminodes inserted at or near the mouth of the tube and 
more or less distinctly spreading stigmata. Another group consisting of 
Sabicea Aubl. and its allies: Pauridiantha Hook, f., Pamplethantha 
Brem., Stelccttantha Brem.. Commit heca Brem.. Pot cilocalyx Brem., 
Rhipidantha Brem.. Tcmiioptcryx Hook. f. and I'cntaloncha Hook, f., all 
provided with heterostylous flowers, a 2-, 4- or 5-locular ovary whose cells 
are in the upper half divided by false septa, axile placentas which, as the 
false septa penetrate in them for some distance, are more or less obcordate, 
stamens which at least in the long-styled flowers are inserted in the middle 
of the tube, and more or less cohering stigmata. A third group, formed 
by Miissanida L. and some other genera, is characterized by a curious form 
of heterostyly, the long-styled flowers being female and the short-styled 
ones male; the genera belonging to this group, however, have not yet been 
sufficiently studied. Still less is known of the remaining ones, and for 
this reason the position of the genus Pomazota Ridl. can not yet be 
satisfactorily ascertained. 

The most important characters of Pomazota appear to be the stiff hairs 
present on all the young parts but especially conspicuous along the margin 
of the leaves, stipules, bracts and calyx-lobes and also on the midrib of 
the corolla-lobes, the terminal capituliform inflorescence with its 4, 5 or 
8 involucral bracts, the presence of a hair-ring in the upper part of the 



190 .MM 1!\\1. OK Till \K\ni.l> MIBOKKTI M I vol. xxviii 

corolla-tube, the insertion of the stamens at or below the middle of the 
tube, the short and thick, rectangularly spreading stigma-lobes, always 
protruding beyond the anthers and the ring of hairs in the corolla-tube, 
and finally the globose capsule which in the end opens by the disintegration 
of a cell-zone at the base of the calyx, after which the upper part including 
the calyx and the rather conspicuous disk is thrown oil in the form of a lid. 

The nearest approach to these characters is found in the genus Klossia 
Ridl. Its only species is a nearly glabrous, thin leaved plant, which at 
first sight looks rather unlike the hirsute Pomazota species. In reality, 
however, it differs from the latter in minor points only. Its inflorescences 
are somewhat less strongly condensed, the brads being smaller and the 
flowers distinctly pedicellate, the bracts and the rather large, in the bud 
overlapping, calyx-lobes are eciliate. the stamens inserted a little wax- 
above the middle of the tube and provided with papillate instead of 
glabrous filaments, and the stigmata are obovate and flattened and remain 
attached to each other. The corolla-tube, however, is provided at the 
upper end with a ring of hairs, and the fruits open with a lid. The 
disintegration-zone on the other hand, lies inside, not outside the calyx, 
so that the latter persists on the open fruit. 

Some other genera belonging lo this tribe resemble Pomazota in the 
nature of the inflorescence. They are Sid, robomhyx Brem.. a new genus 
to be described hereafter, Knnania Hook, f., Campanocalyx Yah. 
Myrioiicuron R.Br., Polysolcnia Hook. !".. I .cptomisclius Drake, Mourctia 
I'itard and Luc'nuua DC. None of them, however, appears to be a close 
ally. 

The only species of Sidcrobombyx shows a strong resemblance to 
Pomazota. Its large ovate acuminate stipule- are indistinguishable from 
those of the latter; its inflorescences are terminal and capituliform. and, 
in the same way as in some of the Pomazota species, soon pushed aside by 
a branch arising from the axil of one of the two highest leaves: the capitula 
moreover are surrounded by large bracts, and the calyx-lobes are. like 
those of /'. ca pit at a and /'. assitnilis, densely hairy. The hairs themselves, 
however, are of a different kind; the young leaves are not covered with 
stiff rust-brown hairs like those of the Pomazota species, but with the 
same silky reddish brown pubescence which gives the young leaves in the 
genus Xantlio[)hvtiim Reinw. ex BI. and in the nearly related and perhaps 
not sufficiently distinct uenera l'a<di<a/y.\ Pierre ex I'itard and Xantho- 
phytopsis I'itard their peculiar lustre. The hairs on the bracts and 
calyx-lobes too are soft and thin like those covering the young leaves and 
not stiff like those of the Pomazota species. This, however, is by no 
means the only difference. The capitula are not surrounded by 4, 5 or 8 
ovate, oblong or spathulate brads, but by two very large reniform ones; 
the corolla-tube is not provided with a ring of hairs near its upper end. 
but the whole upper halt is densely villous on the inside, and the fruit is 
not a capsule opening by a lid, but a dipyrenous drupe. In the only 
specimen which could be studied the filaments, moreover, proved to be 



19471 HREMEKAMP, THE (JEMS POMAZOTA 191 

much shorter than in the Pomazota spec ies. whereas the elavate style was 
longer; the latter proved to be shortly two-lobed. The shortness of the 
filaments and the comparatively great length of the style suggest that the 
specimen represents the long-styled form of a dimorphic species. 

In the genera Krmama and M vrionrnron too the flowers are apparently 
heterostylous, but the heterostyly is here probably combined with dioecism. 
The tvpe-species of the genus Kniuniia at least was based on a specimen 
with sterile anthers, and of the flowers of K. ophioglossoides Drake and 
A", tonkinensis Drake figured by Pitard in Lecomte, Fl. Gen. Tndo-Chine 
3: f. 16 (8, 9), the first are long-styled and maybe female, whereas the 
second are short-styled and, as the stigmata seem to be rudimentary, 
probably male. As the description of the vegetative parts of these two 
species do not reveal appreciable differences, it is not impossible that they 
are conspecific. Similarly the description of Myr'umcuron tonkincmc 
Pitard (op. cit. 193) appears to be based on a male specimen and that of 
a/, pubiflorum Pitard (ibid.) on a female one. The fruits of Myrionrwou 
are exsuccous dipyrenous drupes whose pyrenes open ultimately on the 
inner side; the fruits of Kcenania arc unknown. Campaiwcalyx ap- 
parently comes very near to Kroiania, from which it differs, however. 
conspicuously by its campanulate calyx: its floral mechanism being as yet 
incompletely known. 

Polysplenia is very imperfectly described, but it seems to me that this 
genus'too is heterostylous. the type-specimen representing the short-styled 
form. At any rate, as its stamens arc inserted in the upper part of the 
tube and overtop the stvle, the genus is apparently no near ally of 
Pomazota. Its fruits are unknown. The description of Lcptomischus 
Drake, whose fruits open in the same way as those of Pomazota and 
Klossia, does not differ very much from that of Poly sol ruia, and I therefore 
consider these two genera closely related. In Mount la Pitard too the 
stamens are inserted in the upper part of the tube. As the floral mech- 
anism of all these genera is quite different from that found in Pomazota 
and Klossia, they are apparently not very nearly allied to them. 

The capitula of Liu ma, a are naked and therefore not readily comparable 
to those of Pomazota and Klossia. In its truncate calyx and thick, smooth 
testa the genus differs moreover so considerably from the other members 
of the tribe that its inclusion in it seems hardly justified. 

Capsules opening in the same way as those of Pomazota and Klossia are 
found in Argostcma Wall. Tn the shortness of the corolla-tube and in the 
syngenesious anther, this genus, however, possesses characters which give 
it a rather isolated position in the tribe. Perhaps of more importance are 
the points of resemblance between Pomazota and Klossia and the genus 
Ophiorrhiza L.. whose capsules are also apically dehiscent. The partial 
inflorescences are cymose like those of the two first-named genera; the 
stamens are inserted in the lower half of the tube and the style overtops 
the anthers. However, as none of these characters are confined to these 
genera, their value should not be overrated.

Pomazota n plans backer ex Hrem. seems at first sight to differ essen- 
tially from the oilier species by its decumbent and creeping shoots and the 
small size of its leaves and capitula. A more detailed analysis, however, 
does not corroborate this view, for important points of difference are not 
brought to light. The resemblance in the vegetative parts of the other 
species is very strong indeed. Pomazota YanUnncaii Hrem. is recogniz- 
able by its small size and by the scabridity of the upper side of the leaves, 
P. scabiosijoPia Hrem. by its leaves, glabrous on the upper side, and 
P. simalumisis Hrem. by its pseudo-dichotomy, but the vegetative parts 
of the six remaining species are almost indistinguishable. The ovate- 
acuminate stipules end in an undivided tip in eight of the ten species 
recognized in this paper, in P. simalumisis and /'. scabiosijlora in two 
fairly long, parallel teeth. 

With regard to the position of the inflorescences the ten species form 
two easily distinguishable groups. In the first there is never more ;han 
a single inflorescence at a node, whereas in the second the majority are 
found in pairs. In the second group the peduncles are moreover always 
provided with a pair of scales at the base, whose median position proves 
them to be the stipules belonging to a pair of suppressed leaves; in the 
first group these scales arc always wanting. Their presence proves that 
the inflorescences in the second group are not really axillary, as they might 
seem at first sight, but that they are borne by axillary brachyblasts con- 
sisting of a single, very short internode; in reality they are terminal. In 
the first group too the inflorescences are terminal, but here they are found 
at the end of an ordinal) leafy shoot. They are. however, soon overtopped 
by one or, rarely, two innovation-shoots developing from the axil of one 
of tin- two highest leaves or of both of them. If a single shoot develops, 
the inflorescence becomes pseudo-axillary, the innovation-shoot forming 
the continuation of the main shoot. The stems of these plants, therefore, 
are sympodia. If two innovation-shoots develop {P. simalurcnsis), the 
[Wants become pseudo-dichutomously branched. Another difference be- 
tween the two groups is found in the structure of the capitula. In the first 
group the (lowers are. at least in the axils of the outer bracts, arranged 
in triads or in several (lowered cymes, whereas in the second group they 
are always solitary. 

The involucre consists of 4, 5 or 8 bracts, which differ but slightly from 
the inner ones. Tetramerous and pentamerous involucres occur in both 
groups, but the octamerous ones are confined to the first. In the first 
group the bracts of the tetramerous involucres are decussate, but those of 
/'. rivularis, the only species of the second group in which the involucre is 
tetramerous. form a whorl, and are found to alternate with the four 
immediately following inner ones; in the pentamerous involucres the 
)ks at first sight to be quincunxial, but here too the 
; alternate with the adjoining inner ones. The octamerous 



1947] BREMEKWH". Till. (.KM S POMAZOTA 193 

involucres consist of 4 larger bracts alternating with 4 smaller ones, but 
the morphological value of the latter is not always the same. In P. 
simalurensis the four larger bracts arc decussate, and each of them subtends 
a cyme. The bracts subtending the branchlets of the two lower cymes 
are conduplicate and twisted at the base so that the upper part lies more 
or less in the same plane as the main bract: these two pairs of lateral 
bracts form the smaller bracts of the involucre. In P. assimilis Brem. and 
P. capitata (Miq.) Hrem. the eight involucral bracts are united at the 
base, and thev all subtend cymes. Those subtended by the four larger 
ones' form an outer circle, those belonging to the four smaller ones recede 
a little towards the centre. All the cymes, however, are strongly dorsi- 
ventral, some of the bracts being larger than the others and shifted to the 
outside.' The involucral bracts themselves may therefore easily be taken 
for sterile, for when they are removed, a complete circle of smaller bracts 
is revealed behind which the (lowers are hidden. There is, therefore, an 
important difference between these species and P. simalurensis in the 
arrangement of the involucral bracts. Whereas the arrangement in the 
latter is strictly decussate, that of the involucral bracts of P. assimilis 
and P. capitata is to be regarded either as quaternate or as a somewhat 
modified form of the g-phyllotaxis. The occurrence in the same genus of 
a somewhat modified quincunxial arrangement forms an argument in 
favour of the latter supposition. 

The capitula of P. reptans, P. Vanleeuweni and /'. simalurensis contain 
inside the involucre but one or two pairs of main bracts; the number of 
flowers in these capitula is accordingly but small. In P. assimilis and 
P. capitata the number of main bracts inside the involucre is difficult to 
determine, but it is probably not larger than in the species just mentioned. 
Owing to the large number of flowers in each of the cymes, the total 
number is nevertheless very considerable, larger in fact than in any other 
species of this genus. In the five remaining species the inner bracts form 
a dense rosette. In P. assimilis the first lateral bracts of the outer cymes 
are at the base on each side provided with a patent lobe. In the nearly 
related P. capitata these lobes are usually absent; occasionally, however, 
a single one may be present. The involucral bracts of P. sylvestris Ridl. 
and P. pilosa (Miq.) brem. are car'mate. the five keels forming a prominent 
feature of the involucre. 

In P. assimilis, P. capitata and /'. sylvestris all bracts subtend cymes. 
In the other species belonging to the first group the outer bracts subtend 
pentads or triads, whereas in the axils of the inner ones the cymes are 
reduced to paired or single flowers; in P. reptans the cymes are occasion- 
ally all reduced in this way. In the second group the flowers are always 
solitary in the axils of the bracts, but the presence of a pair of bracteoles 
at the base of each flower proves that the latter represents a cyme. 

In the first group the cymes are sometimes shortly stipitate, the stipe 
being partly or entirely fused with the 1 tei 1 g 1 ict; the flowers, on 
the other hand, are always sessile. In the second group, where the cymes 



194 JOt KWI. OF TIIK \R\Ol •) \KBOKI Tl M |\oi.. xwni 

are reduced to single flowers, the stipe is always fused with the stalk-like 
base of the bract; in /'. rivularis the flowers themselves are shortly pedi- 
cellate, i.e. in this species there is a distinct internode between the 
bracteoles and the base of the ovary. 

The calyx-lobes are ovate-orbicular in /'. pilosa, ovate-lanceolate in 
/'. rcptans, P. Vanlccmcoii, /'. svlvcstris and /'. simaluri usis, oblong in /'. 
rivularis, P. scabiosijlora and /'. hatuensis, linear-oblong in P. assimilis, and 
linear in /'. capitata. In the two latter species they are inside and outside 
densely hirsute; in the other ones filiate. 

In the species of the second group and in P. rcptans the ovary and 
capsule are glabrous: in the other species of the first group they are always 
pilose.

JOURNAL OF THE VRNOLI) MilU.lil II \ 



The Bornean plant to be described below as the type of a new gehus, 
resembles in general aspect the species of Vomazota Ridl., series Sympo- 
diales Brem., but has the silky reddish brown pubescence, the subcapitate 
didymous stigma and exsuccous dipyrenous drupes of Xanthophytum 
Reinw. ex Bl. It differs from the latter and from the nearly related and 
perhaps not sufficiently distinct genera Paedicalyx Pierre ex Pitard and 
Xanthophytopsis Pitard in the position of the inflorescences, which are not 
opposite, but at first terminal and afterwards solitary at the nodes, the 
presence of two large involucral bracts, and also in the iloral structure: 
in the only specimen known so far the style is exserted and the stamens 
included, whereas in Xanthophytum the anthers are apparently always 
exserted and the style included. From Pomazota ii differs not only in 
the nature of the indumentum, in the subcapitate didymous stigma and 
exsuccous dipyrenous drupes, but also in the nature of the involucre, which 
consists of two very wide reniform bracts instead of 4, 5 or 8 much 
narrower ones, and in the inside villous upper half of the corolla-tube. 

The resemblance with Keenania Hook, f., Campanocalyx Val., Myri- 
oncuron R.Br., Polysolcnia Hook. f. and I ,e ptomischus Drake is perhaps 
of greater importance than that with Pomazota Ridl. or Xanthophytum 
Reinw. ex Bl. In all these genera the inflorescences are terminal and 
capituliform, the corolla-tube is villous inside in the upper half, and the 
flowers are apparently everywhere dimorphic. As the new genus is based 
on a single specimen, the conclusion that the latter represents the long- 
styled form of a heterostylous species rests on the resemblance between its 
flowers and the long-styled ones found in the other genera. At first I was 
inclined to regard the flowers of the type specimen of my new genus not 
only as long-styled but also, like those of Keenania, as female, because the 
pollen grains are uncommonly small and thin-walled, but since I have 
found similar pollen in short-styled flowers of Myrioneuron and also in 
Xanthophytum, I have dropped this supposition. 

The new genus differs from Myrioneuron in the presence of two large 
involucral bracts and in the nature of the pyrenes. which are apparently 
indehiscent, from Keenania and Campanocalyx in the narrowness of the 
calyx-lobes, from Polysolcnia in the entire stipules and from Le ptomischus 
in the dipyrenous drupes.

On one of the two labels attached to the specimen the height is given 
as 18 feet, but on the other, which is apparently the original one. as 18 
inches (18"). As its nearest allies are all comparatively low plants with, 
as a rule, unbranched stems, I have assumed that the latter is right, and 
that the preserved shoot represents the whole plant, the roots only excepted.

slender with narrow leaves and the lower glumes are longer, narrow, and 
acute; the spikelets are verv young.

In the explanation of the plate only the ternary combination appears.

hut because of the use of the word nisi (as well as the absence of the 
binomial from the explanation of the plate) there is at least the possibility 
that the name should be regarded as a provisional name and therefore 
invalid. 

Paramapania Montana (Lauterb. & K. Schum.) L'itt. also seems to be a 
provisional name |"If it (i.e. T/iora, osta< hvuoi montanum) turns out to 
be the same species, the name of the latter (i.e. Paramapania amhoincnsis) 
should be altered in P. Montana Uitt."|. 

And finally the combination Thoraiostut livitm par\'i/>ractra (C. H. 
Clarke) Kiikenth. does not seem to satisfy the requirements of Art. 44. 
The name was published as follows: ' Tli. parvibractea (('. H. Clarke) 
Kiikenth. comb. nov. - 77/. montanum Suringar." 

There is nothing in the citation to show upon what species of Clarke's 
Kukenthal based his new combination, though it may be presumed it was 
II ypolytrnm parvibractea. The citation of '///. montanum Yalckenier 
Suringar and reference to the (much later) work of I'itt ion leads one to 
this presumption, but it is no proof.

tentatively assigned to sect, (subg.) Halostcmma. Uittien ll.cc. records 
it from Xelherlands New Guinea and refers it to subgen. Pandtuioscirpus. 
Brass's specimen is an excellent one with two immature inflorescences and 
four mature infructescences. There is an elongated subhorizontal rhizome 
about 8 mm. thick with a dense tuft of leaves at the end. The leaves are 
up to 1 m. long and about 1-1.5 cm. wide, long attenuate to the Aliform 
very scabrous tip, but not much narrowed to the somewhat conduplicate 
base. The scapes are about 10 cm. long and the inflorescence about 3.5 
cm. long and 2-2.5 cm. wide; the nut is 7-9 mm. long and 3.5-4 mm. wide.

The typical form of the species has been recorded from Malaya,

closely connected with one another and the typical form by intermediates; 
he refers (1939, I.e.) Brass 7382 from the Palmer River, Papua (which I 
have not seen) to var. petiolata (C. B. Clarke) Uitt. I.e., which appears to 
be pan-Malaysian. Carr 12772 from Koitaki. Papua, in herb. Canberra, 
also appears to belong to this variety; it was referred to M. petiolata 
C. B. Clarke by Kukenthal in Kngl. Bot. Jahrb. 69: 261. 1938. Brass 
3046 and 13896 agree with one another as to foliage, which approaches 
that of var. augustifolia (Uitt.) Uitt. rather than var. petiolata, but no. 
13896 has the short spikelets about 1.5 cm. long of the typical form on

judge from the description of the leaves of f. latijolia and the width of the

was to regard the type of .1/. Ledermannii Kukenth. {Ledermann

with .1/. Moseleyi. Mapania Moseleyi I", latijolia is then to be regarded as 
based entirely on Brass 7384 (which I have not seen) which differs from 
the type in having no stem leaves besides the characters given in the Latin 
diagnosis. Brass 12804 and 13420 have each two stem-leaves; the leaves

Brass 2705, 8141, White 810, and Schlcnkcr's specimen correspond more 
or less to C. diffusus var. macrostachyus I'.oeck. and Brass 8141 was so 
determined by Kukenthal. But Kukenthal has also determined Brass 
7690 as belonging to this variety, though to me the specimen appears to 
be at least as close to the typical form as is Brass 8445, determined by 
Kukenthal simply as C. diffusus. The species is somewhat variable and 
two entities may indeed be involved but to judge from the series of speci- 
mens seen by me from Malaya, Philippine Islands and Queensland and 
those cited above, var. macrostachyus is too closely connected with the 
typical form by intermediates to warrant nomenclatural recognition. The 
degree of spreading of the glumes, which has been stressed as a distinguish- 



JOURNAL OF Till \li.\OI I) \KIH>KI II \l 



ing character, seems in depend to some extent on variations in conditions 
during the drying of the specimen and to some extent also on the 
physiological state of the plant at the time of gathering. The length and 
the direction of the mucro on the glumes are certainly inconstant. 

Cyprrus pubisquama Steuri. and C. ditlusus var. macrostachyus Hoeck. 
appear to have been founded on the same type, or at least on the same 
collection. The latter ternary combination has priority over ('. dittusus 
var. pubisquama (Steud.) Hook. f. (1900), a combination made inde- 
pendently at a later date by Kukenthal (1924. I.e.). Cyprrus ditjusus f.

This wide-spread tropical species seems not to have been recorded 
previously from the Solomon Islands.

'Idle specimen seen consists of a single culm with a very short piece of 
rhizome attached. The label bears the determination 'Cyperus cinereo- 
brunneus Kiikenth. sp. nov." There is no evidence that a description 
has been published or even drawn up. 

The species appears to be most closely allied to ( '. subpapuanus Kiikenth. 
but has narrow leaves, the glumes incurved to the tip with smooth not 
scabrous keel and with more numerous nerves, acute nuts and a longer 
style. The narrow leaves, incurved tips of the glumes and acute nut 
recall C. mcistostylus S. T. Blake, but the leaves are more numerous, the 
spikelets are more distinctly digitate, the nut is relatively shorter and the 
style is longer. It somewhat resembles the Australian C. scmifvrtilis S. T.

Blake in appearance and in that the lowermost glumes are smaller and 
empty, but it differs in that all the flowers (except perhaps the one

a young inflorescence, another ;i mature and the third an over-mature 
inflorescence. One culm has the uppermost leaf much shorter than the 
culm; on the others the leaves are very long, up to 42 cm. 

The species is allied to ('. tetraphyllus R.Br., (\ subpapuanus Kukenth.. 
('. papuanus Ridl. and ('. pedum ulosus V. Muell. In appearance it re- 
sembles rather closely the Australian ( '. tetraphyllus, hut differs in the less 
digitate spikelets with longer relatively narrower, less broadly rounded, 
less strongly incurved glumes with more numerous nerves, anthers with 
non-set ulose tips, the nut decidedly shorter than the glumes, rather nar- 
rower and more acute with more deeply concave sides, and in the pilosulose 
stigmas. From the other three species it differs in the narrower leave.-; 
from ('. sub papuanus it is further distinguished by the non-scabrous keel 
of the scarcely mucronate glumes which are scarcely excurved at the tip 
and have more numerous nerves, and by the acute rather than obtuse tip 
of the nut; from ( '. papuanus, of which the ripe nut is unknown, it is 
further distinguished by the spikelets not digitate, the broader loosely 
imbricate glumes and the smooth tips to the anthers; and from C. 
peduneulosus it further differs by its fewer bracts, smaller narrower 
spikelets less digitately arranged, the rather smaller more obtuse less 
coriaceous muticous glumes, much shorter style and stigmas, and (relative 
to the glume) rather larger nut with more deeplv concave sides and more 
acute tip.

In Pflanzenr., kukenthal (1936) refers Brass 1457 to var. floribundus 
Kukenth. while Can- 15451 is a syntype of var. atrocastancus Kukenth. 
Judged from the material in the Australian herbaria the species varies 
somewhat in size and degree of division of the inflorescence, colour, size 
(2.6-3.5 mm. in length), and degree of inrolling of the glumes and in the 
shape of the nut. The nut varies in outline from obovate to ovate-elliptic 
with the apex obtuse to more or less acute; in length it is about half as 
long as the glume. Mueller's type specimens have elongated rays with 
rather pale coloured glumes; some of the inflorescences are overmature. 



Other 



specimens, particularly when immature (as in the case of Carr 



15451), have intensely coloured glumes, sometimes nearly black. Cv perns

C. B. Glarke in Jour. Linn. Soc. 21 : 29-30. 1884 has set out the evidence 
for treating Scirpus Miehe/ianus H. [Cyperus M it In litmus (L.) Link] as 
generic-ally distinct from Cyperus pygmaeus and. although the differential 
characters are not always so obvious as implied by Clarke, I believe his 
conclusions to be correct. Kukenthal in Pllanzenr. 101 (IV. 20) : 14 and 
311 regards .S'. Mkhelianus as a somewhat anomalous species of Cyperus 
differing only in the spiral, not distichous glumes, and entirely ignores the 
minute differences in style and nut structure discussed by Clarke. But

even if the two forms were admitted as congeneric il seems impossible to 
me to treat C. pygmaeus as a subspecies iA ( ". M'n hrliauus as has been done 
by Kiikenthal, I.e., 312. following Aseherson cv Graebner. 

The two collections cited above consist of greatly elongated plants 
answering more or less to kukenthal's ( '. Mit hdhinus subsp. pygmaeus f. 
filijolius (Franch. & Saw) Kiikenth.. I.e.. 314. and Brass $439 was received 
labelled as such. But similarly elongated individuals are quite common 
in numerous annual Cvperaceae and at least in most cases are due to local 
environmental conditions, and it seems unite unnecessary to distinguish 
them taxonomically.

A species widely spread in the ( )ld World, but in New Guinea previously 
known from North-Kasl New Guinea only. Valckenier Suringar. in Nova 
C.uin. Hot. 8: 697. 1912 cites "Cyperus globosus forma strietus CI." from 
Netherlands New Guinea. Such a combination was not made by Clarke 
and apparently C. globosus var. strietus C. H. Clarke was intended. 
Kiikenthal in Ptlanzenr. KM (IV. 20) : .S.S.S. 1936 cites as a synonym of 
C. globosus var. nilagir'nus (Hochst.) C. B. Clarke "C. globosus f. stricta 
Suringar, Het gesl. Cyperus in d. Mai. Arch. (189S) 58, t. II, fig. 12; non 
C. B. Clarke"; this appears not to refer to New Guinea specimens. 

Brass's specimens are much closer to the typical form of the species than 
to any of the described varieties. His SMW has the nut broadest at the 
middle and Kiikenthal has in MS. suggested distinguishing it as a variety. 
But from the material of the species in the (Queensland Herbarium there 
seems a perfect intergrading series from such oblong-elliptic nuts to the 
much more usual obovate nuts; in other words the widest part of the nut 
is at or a little above the middle, and in the latter case the nut is sometimes 
narrowed to a greater degree towards the base than towards the apex.

These specimens were cited by Kukenthal in 1938, I.e., as C. ornans. 
The names Cyperus ornans and Cyperus stenophyllus were published 
simultaneously. Under these circumstances, according to Art. 56 of the 
International Rules of Nomenclature, "the author who first adopts one of 
them, definitely treating another as a synonym or referring it to a subor- 
dinate group must be followed." Accordingly, C. stenophyllus must be 
used for the species in its extended sense and Kukenthal erred in changing 
his earlier treatment in 1936. 

T do not think that the two species described by Yalckenier Suringar 
can be distinguished from one another. As here understood C. steno- 
phyllus is very close to the Australian C. Bowmanii V. Muell. ex Benth. 
from which it differs in that the spikelets are slightly thicker, more 
numerous and rather more loosely arranged on the rays, and the base of 
the plant is harder and moderately swollen, with dark-coloured sheaths. 
It appears to be restricted to the islands north of Australia from Java and 
the Philippines to the Solomon Islands and Tonga.

Carr's collection was cited by Kukenthal (193S. I.e.). Brass's speci- 
mens appear to be the only other specimens of this species known from 
Papua. The species has been reported from North Kast and Netherlands 
New Guinea and extends northwards and westwards to South China and 
India and has been introduced into Reunion and Mauritius. The f. 
decolorans covers those (herbarium) specimens with paler coloured or 
faded spikelets and appears to have no real taxonomic significance; see

This widely spread species has in the literature of New Guinea usually 
been called Cyperus pennatus Lam. 1 am indebted to Dr. E. D. Merrill 
for a copy of the appropriate passages and a tracing of the plate connected 
with Houttyns binomial. To Merrill's discussion of the name. I.e., it may 
be added that : 

1. No name is directly connected with Houttyn's description of a plant 
on [). OS, lull there is a marginal reference toIMaat LXXXVIII, fig. 1. 

2. On ]>. | III | of this volume, in the explanation of the plates, the 
binomial Cyperus Java nicies is definitely applied to l'laat LXXXVIII, 
fig. 1, and reference is made to p. 68. 

3. The plate consists of a very good figure of an inflorescence with an 
enlarged figure (marked a) of a spikelet. Reference to this "a" is 
made in the description. 

The validity of the binomial appears to rest upon the association of the 
name in the explanation of the plate with either the figure or with the

description or with both. That is, the formal description of the species 
is divided into pails, each occurring in different disjunct places in the 
volume. It is questionable whether this is in strict accord with either the 
letter or the spirit of Art. 44: "The name of a species ... is not validly 
published unless it is accompanied ( I I b\ a description-. . . .or (3) by a 
plate or figure showing essential characters" (italics mine). 

Kiikenthal, in Engl. Bot. Jahrb. 69: 257. 1938, refers Carr 11390 to 
C. pennatus var. Armstrong} (Henth.) kukenth.. a combination made in 
Ptlanzenr. 101 (IV. 20) : 479. 1936. and based on C. Armstrongii Benth. 
Fl. Austral. 7: 289. 1878. Bentham cites four collections after his 
original description: Port Essington. Armstrong; Port Darwin, Schultz 
731; Percy Islands. .1. Cunningham; Rockingham Hay. Dallachy. 
Dallachy's specimens belong to C. tetracarpus Boeck. I have not cer- 
tainly seen specimens of the other collections cited, though Domin in 
Biblioth. Bot. 85:440. 1915 refers Cunningham's specimens to what is 
here called C. javanictts and Sdmltz 731 to Mariscus Armstrongii C. B. 
Clarke. C. B. Clarke in Kew Bull. Add. Ser. 8: 17. 1908, describes 
Mariscus Armstrongii sp. n.. citing "Cv perns Armstrongii, Benth. Fl. 
Austral. 7: p. 289. quoad Armstrong, n. 616." This had best be inter- 
preted as typifying Bentham's species on Armstrong's plant and then 
transferring the species in its emended sense to Mariscus* In any case, 
I do not see how Carr's immature specimen in herb. Canberra can be 
distinguished from C. javanicus.

This collection is an isotype (or at least a haplotype) of Kukenthal's 
variety which is diagnosed with the words "Culmus 70 cm. altus. Squamae 
fuscae." It was also cited merely as ('. lloloschocnus R.Br, by him in the 
same year in Engl. Bot. Jahrb. The material seen by me consists of o„e 
complete culm about SO cm. long beneath the inflorescence with innovation 
shoots at the base and a second inflorescence with the upper part of the 
culm. The glumes appear to be dull brown, but under the microscope 
they are seen to be more or less variegated, varying from straw-brown to 
dull purplish brown. The colour of the glumes varies considerably, partly

the drying of specimens also produce variations in the colouration of the

Apart from Brass's specimens the species is known only from the far

Widely spread in Africa. I topical and temperate Asia and Australia, and 
in the West Indies. In New Guinea previously known from Netherlands 
New Guinea, North-East New Guinea and from "Proclamation Creek" 
(F. Mueller, I.e.). 

This widely spread species has been most commonly known as ( ". 
umbcllatus. The combination is usually attributed to Bentham in Fl. 
Hongk. 386. 1S(»1, though Kukenthal in IMlanzenr. 101 (IV. 20) : 523. 
1936 attributes it to ('. B. Clarke in Jour. Linn. Soc. 20:296. 1883. 
Bentham. I.e., founded the combination on "Matiscus umbcllatus Vahl ; 
Kunth Enum. ii. 118." The name Mariscus umbcllatus Vahl. Enum. IM. 
2: 376. 1806, was based on Kyllinga umbcllata Rottb. Descr. et Icon. 15, 
t. 4, fig. 2. 1773; this name is not cited by Bentham, probably for the 
reason explained on p. 20 of the preface: "With regard to the synonymy. 
I have thought it generally unnecessary to repeat that which is already 
detailed in the general works referred to in the case of each well-known 
species." In El. Austral. 7: 289. 1878, Bentham cites the name C. 
umbcllatus, Benth. El. Hongk. 3S(> with Kvllin-a umbcllata Rottb. in the 
synonymy. There seems little doubt that Bentham, in the last analysis, in 
his own mind definitely based his combination on that of Rottboell's, and 
even excluding the reference in Fl. Austral, the combination would be 
valid according to some recent interpretations of Art. 37 of the Interna- 
tional Rules of Nomenclature, as there is an implied, indirect reference to 
Rottboell (see Airy-Shaw in Kew Bull. 1938: 256, 1938, and Sprague, Kew 
Bull. 1939:322-3. 1939). It is however illegitimate because of the 
earlier C. umbcllatus Burm. f. Fl. Ind. 21. t. 9, fig. 1. 1768, and C. umbcl- 
latus Roxb. Fl. Ind. 1: 205. 1820. Kyllinga umbcllata Rottb. was based 
on an African plant which is nowadays regarded as distinct from the form 
represented by the New Guinea plant. Vahl apparently did not

distinguish the two and this broadened concept was accepted by Kunth 
and Bentham. Thus Benthams name belongs to the form described by 
Rottboell, but his description, ll.ee. refers to the form described by 
Linnaeus. Mant. 2: 181. 1771. as Scirpus cypcroides, now known as

The species extends from SK. Asia to Madagascar. Australia and Fiji. 
Brass's specimens had been previously determined by Svenson. Can's 
specimens were referred to "Ilclcocharis cquisctina Presl" by Kiikenthal in 
Engl. Bot. Jahrb. 69: 257. 1938, but well-developed specimens of E. 
equisetina are distinguishable by having firmer culms, firmer, broader, 
shorter, subtruncate (not rounded), more or less sinning glumes which are 
somewhat incurved when dry, hypogynous bristles more slender and quite 
free from one another (not conspicuously connate at the base), long- 
apiculate anthers, and bright-brown nut with acutely costulate margins 
and more regularly arranged external cells. Hut Can's specimens are not 
very satisfactory and arc in tlower only.

This species falls into the group of Lithocarpus fenestrata (Roxb.) 
Render from which it differs in thinner leaves with more numerous and 
unusually prominent, strongly etched lateral veins and veinlets, smaller 
cups with minute scales, and hemispheric, not ovoid acorns. Lithocarpus 
Pavici (Hick, et A. Camus) Chun* is not unlike in certain respects but in 
that species the silky pilose acorn is borne on a pedicellate cup.

The last named specimen, a duplicate of which was presented to the 
Herbarium of the Botanical Institute, Sun Yatsen University, by Mr. H. 
Green, late Superintendent of the Hongkong Botanical Garden, had been 
misidentified as Qucirus tHv'n olaruni 1 lance, a very different plant with 
a thin, fragile cup described by Hance as 'cupulis cupuliformibus 10 lin. 
diametro squamous brunneis tomentelb's in lamellas 6 indistinctas denti-

combination under Lithocarpus, cited above, is unfortunately based on 
McClure's specimen which rightly belongs to the new species now proposed.

The acicular reflexed squamae on the fruiting involucre approximate 
those of Lithocarpus Garrett hi mi (Craib) Chun* and Lithocarpus 
Skanniana ( Dunn) Rehd.. but in other respects, this new species is totally 
different from the plants mentioned. 

This truly remarkable large handsome tree was first discovered by the 
writer, when he was about to embark for England in 1930, in Hongkong 
near the Peak in a small wood behind a residence above Luggard Road. 
Messrs. C. L. Tso and Li Yiu were put on the alert for ripe fruits which 
were subsequently collected in abundance and sown in the nurseries of 
the Botanical Institute and the Hongkong Botanical Garden. 

If, as early as 1875. Hance in describing Ca.stanopsis Lamontii** should 
regard it "strange that this fine tree which grows in a locality which must 
have been many times visited by former collectors, should have so long 
remained undetected." how much more true is the remark quoted when 
applied to a companion which openly defied detection for a further period 
of over half a century. 

This new species is respectfully dedicated to the former Chancellor of 
Sun Yatsen University, Chow-Lu. L.L.I)., Leipzig, under whose adminis- 
tration the Experimental Garden of the Botanical Institute became an

This species differs from L. Hancvi (Benth.) Render in slender blackish 
not grayish branchlets, much thinner smaller leaves and smaller cup with 
less distinct scales arranged in fewer zones. From /.. itrapliylla ( Hance ) 
Rehd., with which this new species seems to be more closely allied, it is 
at once distinguished by the ternately coalescent not solitary acorns. 
LithocarpHS tvrnal'nupula Hayata. of which we have authentic specimens 
from Formosa, differs in having a thicker deeper cup with prominently 
swollen scales and larger acorns. These four species belong to a 
closely related group but seem to be specifically distinct.

The fruits in some of the Hainan specimens show some variation. 
ranging from generally hemispheric to depressed globose in form, otherwise 
all the collections are very uniform.

My nephew, the discoverer of this new species, was attracted to the 
tree from a great distance by the scintillating foliage when the sun shone 
on its crown. The rustling tendency of the leaves is due to the partially 
flattened petioles.

This remarkable species is unlike any other known to us in the peculiar 
structure of the cupule. The cupule is composed of two parts different 
from each other in texture, a cup proper, hemispheric and woody, and an 
abruptly expanded broad circular limb which, in the living state must 
presumably be fleshy, eventually becomes thickly coriaceous and strongly 
undulate with conduplicate upwardly curving folds alternating with 
decidedly indented and more or less revolute intervals.

inadequately described Annamese plant known only in very young fruit, 
from which the Chinese tree differs in longer petiolate generally ovate 
leaves, dentate from mar the base and terminated by an unusually broad 
acumen. The fruits, though not exactly comparable in stage of growth, 
in our species have less distinct but more tumid cup-scales and are borne 
on a much shorter and stouter peduncle. 

This new species is named after Professor S. S. Sin, former Head of the 
Biology Department of Sun Yatsen University, under whose able and 
energetic direction several expeditions despatched to little known regions 
in Kwangsi and Hunan procured much new phytogeographic data of great 
scientific interest and value. The collections, as yet only partially studied, 
are proving to be unusually rich in undescribed species.

The genus Parabarium Pierre is characterized by compact, corymbose 
cymes with the apices of the corolla-lobes abruptly inflexed in aestivation. 
and by follicles which are prominently dilated at the base and somewhat 
abruptly attenuate! upwards into a long, slender beak. In indumentum, 
P. Iluaitin^l approaches P. vdiitimtm Pitard, but the Indo-Chinese 
species, in addition to other morphological characters, is at once dis- 
tinguished by much larger leaves of a different form, larger inflorescence 
and fruits. On account of the densely flowered inflorescence and the 
form of the fruit, our plant seems to be more closely allied to /'. mkranthum 
(Wall.) Pierre, but that species, like all other species hitherto ascribed to 
the Chinese flora and enumerated by the junior author in 1934,* are 
totally glabrous. 

In the spring of 1944, the governments of Kwangtung and Kwangsi 
jointly dispatched a botanical party into the interior of the Shi-\Yan-Ta 
Shan. KwangtunK-Kwangsi border, in search of gummiferous plants 
furnishing possible substitutes for rubber. The survey and identification 
of the plants collected were entrusted to this institute. Our collector, 
S. H. Chun, succeeded in gathering over thirty species belonging to various 
families and orders, all producing more or less abundant latex, those of 
the Apocynales including Chounnorpha macrophylla (Roxb.) G. Don, 
Parabarium mkranthum (Wall.) Pierre, and the newly proposed species 
described above being the most promising. The latex was first coagulated 
by acetic acid in the field, and upon refining by government laboratories. 
has been found, at least in some cases, to be serviceable in the electrical 
and automobile industries. 

This new species, which undoubtedly will become economically 
important, is named after and dedicated to Professor Tang Tsic Yee, 
Dean of the College of Agriculture, Sun Yatsen University, to whose 
support our Institute owes much of its progress, and through whose 
life-long devotion to his chosen field, scientific agriculture in South China 
is beginning to benefit the daily life of the people.

MERRILL, DESVAl X'S JOl RV\1 ML 



NOTES ON THE DATES OF ISSUE OF DESVAUX '< 
JOURNAL DE BOTANIQUE 



Volume one of this short-lived periodical is dated 1808, it being made 
up of six numbers, 64 pages each, for the months of October. November. 
and December, 1808 (pp. 1-192), and January, February, and March. 
1809 (pp. 193-384). Volume two is dated 1809, and its six parts, also of 
64 pages each, are indicated as April, May, June, July, August, and 
September, 1809; these dates appear on the fascicle covers of the set in 
the Arnold Arboretum library. It is evident from certain corroborative 
data recently located that Desvaux was able to conform to his announced 
plan of publication, fascicle covers p. 4: "Ce Journal paroit dans le 
premiere huitaine de chaque mois, a compter du mois d'octobre 1808." 

An 'Avis aux souscripteurs" pasted on the fascicle cover of volume two, 
no. 6, and repeated on page 4 of the fascicle cover of this number reads in 
part: "Des mutations arrivees dans la Maison de commerce qui s'etoit 
chargee d'abord de faire paroitre le Journal de Botanique, obligent les 
auteurs de suspendre cet ouvrage. jusqirau mois Janvier prochain . . . ." 
Desvaux's plan was then to issue a new periodical commencing in 1810 
under the title Annales de Botanique; this plan was never consummated, 
but beginning in 1813 he did issue several volumes of another run of the 
Journal de Botanique, the remainder of the title considerably modified. 
The full title of the first two volumes (1808-1809) was: Journal de 
Botanique, redigee par une societe de botanistes; that of the second run 
(1813-1816) was: Journal de Botanique, appliquee a 1'agriculture, a la 
pharmacie, a la medicine, et aux arts. It is not surprising that some 
botanical authors have confused these two runs of what were different 
periodicals under the same leading name, one in 1808-09, the other 
1813-16. 

The correctness of the indicated dates of issue of various parts of these 
two periodicals have been questioned, but certain contemporaneous reviews 
have recently been located which clearly prove that the years and months 
indicated for the first two volumes of the first Journal de Botanique are 
correct in spite of a statement by Desvaux (see below) that would seem 
to indicate that a later date (1810), was involved. From these reviews it 
is clear that there was at least some distribution of all of the individual 
numbers within the month indicated for each number, or in some cases 
actually in the preceding month. 

The first statement that I noticed in reference to this periodical was by 
Rafinesque, Atl. Jour. 1: 207. 1833, where he indicated the date of certain 



248 JOl'RNAL <>!•' Till. AIINOI.D AKIiOKITl M 

reprints of his papers as 1809; it is barely possible that on 
out in 1808, however. Later I noticed Ferna' "" 
34: 26. 1932, which is: 

"The title page of Desvaux's Journal de liolanique, tome 1, is dated 
1S0S. but Rafinesque himself stated in Atlantic Journal, i. 207 ("Winter 
of 1888") in his Cronological Index of his own botanical writings, that the 
paper was 'reprinted in Desvaux' Journal of Iiotany. Paris, ISO .' 
Desvaux complicated the (|uestion by himself staling in a volume dated 
1814 that 'Nous avons public en 1810, deux Volumes de 384 pages chacun 
et de 12 gravures' (see Fernald. Rhodora. xxix. 227 ( 1927). Since Vol. 1 
(dati'd 180S) is the only one of the two volumes with 384 pages and 12 
plates (Vol, 2 having 384 and 18 plates), we have Desvaux's word that it 
did not come out until 1810." 

One suspects that Desvaux perhaps meant to say that by 1810 he had 
published two volume-, or perhaps there was not much distribution of the 
various issues before that date. Suspecting that the Journal general de 
la Litterature de France might throw some light on the actual dates of 
publication of Desvaux's periodical, and also on other botanical works 
issued in France between the years 1 7°S and 1841, a somewhat systematic 
examination of that serial was initiated. The data noted in reference to 
the two volume set of the Desvaux Journal de Botanique are summarized 
in the next paragraph. 

Volume 1. no. 1. pp. 1 64 October. 1808 was reviewed Jour. Gen. Lilt. 
France 11:258 | September | 1808*; no. 2, pp. 65-128, apparently not 
recorded, but the fascicle over date is November. 1808; no. 3, pp. 129-192, 
December, 1808. is reviewed in the November-December number of the 
Jour. (urn. Fit). France 11:323. 1808. The next three numbers were 
apparently not recorded, but the fascicle cover dates are: no. 4. pp. 
193 256, January. 1809. but the date at the bottom of the cover is 1808, 
so this part may actually have been printed in 1808; no. 5, pp. 257-320, 
February, 1809; no. 6, pp. 321-384, March, 1809. 

Volume 2. no. 1, pp. 1-64, April, 1809. is reviewed op. cit. 12: 100. 1809, 
this being in the April issue; nos. 2 and 8, pp. 65-192, May and June, are 
reviewed op. cit. 12: 180, May, 180°; no. 4, pp. 193-256, July, is reviewed 
op. cit. 12: 194, the July number; and no. 5, pp. 25 7-320, August, is 
reviewed op. . it. 12: 227. August. 1806. No entry was noticed for No. 6, 
this including pp. 821 884; its fascicle cover date is September. 1809. 

The evidence here is that the editors of the Journal general de la 
Litterature de Fiance actually received copies of the various issues of

Desvaux's Journal de Botanique as they were issued. There would 
therefore appear to he no cause for doubting the correctness of the dates 
of issue as originally published, for Desvaux apparent]) was able to live 
up to his plan of issuing a number each month and in the first eight days of 
each month; in fact some of the numbers actually were printed in the 
month preceding the one indicated on the fascicle covers. 

The record as to the dates of issue of the "second series'" is unfortunately 
not so clear and doubts have been cast on the correctness of some of them. 
It was Desvaux's original plan to start an entirely new periodical in 1 S 10 
as noted above, but apparently the times were not propitious. Three 
years later he did initiate another serial but used the same general title 
that he had for the first attempt, i.e.. Journal de Botanique. Of this new 
serial four volumes were issued, the third volume apparently never 
completed. 

bernald, Rhodora 20: 227. 1927. in his discussion of Dcndrium Desv. 
and Loisr/ruria Desv., for which he correctly accepts the date of publica- 
tion as 1813, says: •Nevertheless. Furopean bibliographers apparently 
have recent information (its source as yet unknown to me) that the part 
of vol. iii, or Ser. 2: 1, containing Dnuinum (p. 36) and Loisr/ruria (p. 
35) was not issued until 1314." However, Xo. 1, pp. 1-43, although 
neither the number nor the pagination is indicated, is clearly the part 
reviewed in the Jour. Gen. Litt. France 16: 30. 1813. as determinable from 
the titles of the papers cited. This would be the January number for the 
year 1818 and the entry proves that number one of this new Desvaux 
Journal de Botanique was actually issued in 1813 and not delayed until 
1814. My attention had been called to an item in Bertolini's Flora 
Italica 2: 377. 1835. in his discussion of Primula suavrolrns R. & S. in 
which he refers to an entry in Desvaux's Journal de Botanique '•torn. 4. 
p. 76. anno 1813," which seemed to confuse the issue. Checking the 
reference, however, indicated an error on Bertolini's part, for the Primula 
suavrolrns entry is in Desvaux's Jour. Bot. 2: 76. 1813, not in volume 
four, again confirmation that volume two was issued in 1813. 

As Fernald notes, the signatures (every 16 pages) are dated at the 
bottom of the first page of cadi beginning with p. 49. February. 1813, and 
continuing to June, 1813 (p. 273). It is not claimed that these monthly 
dates are actually the dates of issue, but this might well be the case. 
This system of dating the signatures was continued through volume 2, p. 
1, July, 1813, to p. 257. December, 1813, but was abandoned in volumes 
three and four. Volumes three and four are dated 1814. On page 285 
of volume four Desvaux says: "Les trois derniers Xumeros du 3." 
volume pour 1814. paraitront avec les premiers Xumeros du 5." volume 
commengant V annee 1815." This explains, in part, the incomplete volume 
three but throws no light on the difficulties that the editor may have had 
with the printers. In all but one of the sets of this periodical that 1 have 
seen, volume three closes abruptly with page 192. and I judge that it was 



250 IOI KIWI. OK TIIK AllNOl.l) \li I'.OK KTl M [mil xxviii 

Desvaux's plan to issue four numbers of 48 pages each. It is worthy of 
note that the set in the library of the New York Botanical Garden contains 
pages ] OS to 240 of the volume under discussion, this indicated as no. 5. 
Maw 1814. But a footnote on page 197 clearly indicates that it could 
not* have been published before February. lSlo; see Hazcn, Bull. Torr. 
Bot. Club 56: 531. 1929. The fifth volume promised by Desvaux for 
1X15 never appeared, and apparently also only certain fugitive issues of 
the last part or parts of volume three for 1814 were actually distributed. 
I know of only the New York copy of vol. 3. no. 5. never having seen a 
reference to an existing copy of no. 0. I have seen no fascicle covers of 
any of the numbers of this second run of Desvaux's Journal de Botanique. 
Apparently the unsettled conditions in Paris associated with the fall of 
the lust empire in 1S14, and the first year or two of the restoration were 
not conducive to regularity in publication of technical periodicals. 



MERRILL, ON Till: IDIAlin <>l 151! WPISI A SOULIKI 



On examining the proofs of Dr. Li's paper on brandisia, this Journal, 
p. 136 his correct elimination of Bonati'> species as a representative of this 
gei \i te 1 U the time Li's paper was prepared it was impossible 
to secure special information from Furopean centers. With the improve- 
ment in communications following the termination of hostilities it im- 
pressed me as desirable to see if the excluded bunaii species of Brandisia 
could be more definitely placed. Suspecting thai the type was preserved 
in the Paris herbarium I appealed to Dr. H. Humbert of the Museum 
d'histoire naturelle, who courteously sent me an excellent photograph of 
the holotype. An examination of this rather clearly indicated that the 
family Scrophulariaceae was nol involved but that probably Brandisia 
Soulici Bonati actually belonged in the Labiatae. 

Turning to Bonati's description it is evident that he did not examine the 
structure of the ovary, for all that he says regarding the innermost set of 
floral organs is "stigmate bifido. lobis brevissimis. Capsula ac semina?" 
Feeling that it was essential that the structure of the ovary be checked T 
appealed to Dr. F. Gagnepain who reexamined the type and reported: 
■Je me hate de vous informer: Que cette espece est une Fabiacee; I 
parce quelle a le stigmate particulier a cette famille; 2 parce que j'ai vu 
tres nettement au moins 2 nucules sur le podogyne au fond du calice. La 
chose est done jugee; ce nest pas une Scrophularicee. Je n'ai pas eu le 
temps de faire de plus amples rccherchcs et de trouver le genre de 
Labiacees auquel apparlient cette espece litigieuse." 

On the basis of the additional information courteously supplied by Dr. 
Gagnepain, the conclusion was reached thai the genus Chdotwpsis Miquel 
(Labiatae), as currently interpreted, was tvpresenlcd by Bonati's species, 
and after a consideration of the published descriptions of the proposed 
species that further Brandisia Souliei bonati (1909) was identical with 
Chclonopsis a/bi flora Fax & K. Hoffm. (1922). So convinced am I as to 
the specific identity of the two, one erroneously placed in the Scro- 
phulariaceae, the other correctly in the Labiatae. that on the basis of the 
original descriptions and without having seen specimens representing either 
of the species, the Fax and Hoffman one is reduced to synonymy and the 
following adjustment in nomenclature is made:

The species is apparently known only from the collections on which the 
two descriptions were based, and all three of the cited specimens came 
from Batang |l'a-an|. Province. Kastern I iliet | Sikang Province, China ] , 
Soulie 5199, "Yargong," collected in 1904 and Limprkht 2221. 2230 
'Bejti-Batang'' and "Batang-Litang," collected in 1914, the last two 
numbers being the basis of Chelonopsis alhijlorii Pax & K. Hoffm. 
'Batang" is I'a-an. ami what Soulie and lampricht designated as eastern 
Tibet, at least as to the "Hatang'' plants, is now Sikang Province, China. 
The published descriptions agree with each other < losely. One of the 
striking characters even in C/n lonopsis, is that most of the leaves are in 
whorls of threes. The three collections came from the same general 
region, but unless duplicates of the lampricht collect inns were distributed 
to other centers previous to the destruction of the Berlin herbarium, 
perhaps the Bonati collection is the sole extant representative of the 

Naturally a botanist studying the Labiatae as did Dunn* in his consid- 
eration of the Labiatae of China cannot be censured for having overlooked 
a species erroneously described some years earlier and misplaced in the 
system not only as to the genus but also as to the family; Dunn recognized 
four species of Chclonopsis as occurring in China. \'or can Pax and 
Hoffman be blamed for overlooking an ample earlier description of a 
species that they described as new and for the same reason. This is an 
excellent illustration of the fact thai to describe a new species is a very 
simple procedure, but to place a suspected new species in its proper group 
and to determine whether or not a proposed species is actually "new," 
(i.e., previously unnamed and undescribed ) is another matter.

This juvenile form has been listed by most recent authors as 
Chamaccy parts obtusa cricoides Boehmer. a nomen nudum first validated 
in 1909 by Beissner (I.e.). This name, however, should be considered a 
later homonym of Rctinispora obtusa var. cricoides Hoopes (1868), since 
Rctinispora obtusa Sieb. cv Zucc. and C. obtusa Endl. are synonymous. 
Retinispora obtusa var. cricoides Hoopes is based chiefly on Chamaecyp- 
aris cricoides Carr. (1855); there can, however, be no doubt that C. 
ericoides Carr. does not belong to C. obtusa, but represents a juvenile form 
of C. pisijera, namely C. pisijera f. squarrosa |Znrc.| Heiss. and partly 
C. thyoides f. cricoides (Carr.) Rehd. As the epithet cricoides has been 
applied to forms under three different species in the genus Chamaecy parts, 
and may therefore cause contusion, its rejection in favor of Sanderi, about 
which there can be no doubt as to the plant meant by it. is in accordance 
with the spirit of the Rules of Botanical Nomenclature (see Art. 4), even 
if Retinispora obtusa var. ericoides Hoopes and Chamaccy paris obtusa var. 
ericoides Beissner are not homonyms in the strict sense of the word; 
moreover, the first two figures of this plant were published under the 
names Juniperus Sanderi and Retinispora Sanderi. 

In the note in Gard. Chron. ser. 3, 25: 287 (1899) on Juniperus Sanderi, 
it is stated that /. Sanderi, a Japanese species, was introduced by F. Sander 
& Co., about 1896, but I have not been able to verify this s

The oldest subdivisional name for this section has been generally over-

to the species belonging to it. it must replace the name Aporarya C. de

The specimen collected by J. F. Mario bears on the label the varietal 
epithet album which agrees with the fact that its tlowers are white even 
in bud. This is the only specimen with white tlowers in the herbarium of 
the Arnold Arboretum and there is none at all in the Cray Herbarium; 
all other specimens collected in (lower have the corolla more or less 
rose-colored to rose-carmine. In none of the floras of the West Coast is 
any mention made of a white-flowered form, although the original descrip- 
tion of R. macrophyllum G. Don (Gen. Hist. Dichlam. PI. 3: 843. 1834) 
says: "corolla alba"; only those later authors who keep A', macrcphyllum 
and R. calijorfiicuw as distinct species describe the flowers of the former 
as smaller and white. This separation is apparently only based on the 
color as given in C. Don's description, ll appears, however, that G. Don 
was in error when he ascribed white flowers to this Rhododendron collected 
by .Men/ies at Fort Townsend. for in his journal edited by C. F. Xewcombe 
in 1923, under the title "Journal of Vancouver's Voyage, April to October, 
1792" Menzies refers twice to this Rhododendron, on p. 20* as A\ politician 
and on p. 49 as "that beautiful native of the Levant, the purple Rhodo- 
dendron"; apparently he identified the Rhododendron of the Vancouver 
region which is in general appearance similar to R. ponticum L., with that 
species he knew from Furope and probably from plants cultivated in 
England, whence it was introduced in 1763 from Gibraltar. As there

occurs no other species of the subgenus Eurhododcndron on the West 
Coast of North America but R. macrophyllum G. Don (R. californicum 
Hook.), the specimens collected by Menzies and compared by him with the 
purple flowered A', ponticum could not have been the apparently extremely 
rare white-flowered form; the explanation seems to be that the flowers of 
the specimens were faded and discolored and looked as if they might have 
been white, as they do in some of the mure recently collected specimens 
before me.* Don also describes the filaments as glabrous, which 
they are not. not even in the white-flowered form; they are densly 
pubescent al least at the lower third. A specimen from the type-locality.

1934, has pink flowers up to 6 cm. across and rather large leaves, 9-15 cm.

have they any connection with the geographical distribution; a specimen 
from Monterey has one of the smallest (lowers that I have seen, about 
3 cm. across and they are pink.

genus into three sections and the second section into two subsections, using 
for his section III, a form of name contrary to usage and, moreover, the 
adjectives in plural are treated as of feminine gender which is grammati- 
cally incorrect (see also my proposal ol changes of Art. 26 of the Rules

pose, therefore, to change the name sect. Baccatar to sect. Euligustrum,

some time before 1^24 and was first offered for sale in I "24 by Jackson & 
Perkins under the name 'Privet Lodense" with the descriptive synonym

There can be but little doubt that all the names cited above belong to

var. tricolor Jacob-Makoy, of which I have seen no specimen; certainly 
Median's figure of it does not represent a form of L. japonicum Thunb. 
which has coriaceous evergreen leaves and would not be hardy near 
Philadelphia. Moreover, the name /.. japonicum has often been applied 
in garden and horticultural literature to L. ovalifolium.

This Ligustrum apparently originated some time before 1920 in the 
garden of Vicary Gibbs of Al'denham, Middlesex, England, famous for his 
collection of rare trees and shrubs. Its characters suggest a cross between 
Ligustrum ovali folium f. aurcum and L. vulgar x. In its general appear- 
ance it resembles very much L. ovali jolinm f. aurcum, but the influence of 
L. vulgarc is indicated by the more compact and smaller inflorescence with 
its axis and branchlets puberulous, and particularly by the shorter corolla- 
tube which is only about U times as long as the corolla-lobes, while in 
L. ova/iio/ium it is two to three times as long as the lobes, and in L. vulgare 
shorter than the lobes. The shape of the leaves is much like that of 
L. ovalifolium, but the variegation is more irregular than in its f. aurcum 
and the leaves of the weaker branches are often entirely green. Since 
writing the preceding description proposing this plant as a hybrid of 
L. vulgarc and L. ovali folium, my attention has been drawn to a note by 
J. W. Besant in Gardeners' Chronicle (I.e.) in which he calls L. Ibota var. 
Vicaryi u a variant from the common and oval-leafed Privets" which 
apparently means a hybrid between L. vulgarc and L. ovali folium. Il 
may be considered a confirmation of the correctness of calling this plant 
a hybrid between these two species, that the same explanation of its origin 
is based on two entirely different and independent sources. The fact that 
the pollen of this plant is normal can not be considered a proof against its 
hybrid origin, for pollen sterility, though prevalent in hybrids, cannot be 
considered an infallible character of hybridity. for there are hybrids with 
normal pollen, as X Platoons accrifolia (Ait.) W'illd. (P. Occident alls > 
orient alls).

WHITE, TWO SPECIES OF \K \l C\KI \ 



NOTES ON TWO SPECIES OF ARAUCARIA IN NEW GUINEA 
AND A PROPOSED NEW SECTION OF THE GENUS 

C. T. White 

On my way back to Australia from the Solomon Islands in November, 
1945, I was delayed at Lae in New Guinea, awaiting transport, and 
decided to visit the Bulolo Valley at Wau for the purpose of seeing the 
fine Araucaria forests of that region. 

Before the war, Wau was the centre of the gold-mining industry of the 
Mandated Territory of New Guinea, and the town and surrounding district 
carried a white population of approximately 2000. Lack of transport had 
fortunately prevented the exploitation of the magnificent forests of 
Araucaria Klinkii Lauterb. and A. Cunninghamii Ait. These two species 
grow intermingled and dominate the rain-forest on the ridges and hillsides. 
The former is an especially magnificent tree and Mr. J. B. McAdam, Chief 
of the New Guinea Forest Service, informs me that he still hopes to find 
a specimen 300 ft. high. By actual measurement he has found trees 
approaching this height, but not quite attaining it. The following notes 
on their systematica and their distribution in New Guinea are offered.

Lauterbach. I.e., mentions that he could find no difference between 
Sayer's specimen and the type from E. Australia. The species is abundant 
in Eastern New Guinea on the Owen Stanley Range and ranges north of it. 
The trees in the field are very similar to those of Australia, where the 
species is very common from sea-level to an altitude of 3000 ft. and shows 
considerable variation in form. I have compared the New Guinea speci- 
mens available to me with much Australian material and can find no 
essential differences. The closely allied A. Beccarii Warb. from north-west 
New Guinea, judging from figures published by Miss Gibbs in the 
Phytogeography and Flora of the Arfak Mts., p. 84, fig. 5, seems to differ 
chiefly in the very much larger cone and cone-scales, the latter measuring 
4 cm. X 8 cm. (exclusive of the indurated point) whereas in A. Cunning- 
hamii Ait. they only average half this size.

As is well known, the species of Aram aria fall naturally into two 
well-defined sections: 

(1) Colymbea Endl. in which the leaves in adult trees are large and 
more or less spreading, the tones large, the seeds heavy and not adapted 
to wind-distribution, cotyledons hypogeal, endosperm transferred in 
germination into the underground swollen hypocotyl. 

(2) Eit.uta Endl. in which the juvenile leaves are acicular and 
spreading, the adult ones small and imbricate, the seeds comparatively 
light and with the accompanying winged scale, adapted to wind-distribu- 
tion, cotyledons cpigeal and spreading in germination like those of Finns, 
hypocotyl slender. 

Lauterbach (I.e.) placed .1. Klink ii Lauterb. in the section En acta. 
where I feel that its true affinities lie. However, Ih'lger in the second 
edition of Die NaUuiichen Fllaiizentamilicn transferred it to the section 
Coi.ymhka. The only affinity with this section is the large size and more 
or less spreading character of the leaves. He also includes here the closely 
allied .1. Hunsteinii K. Sch. and A. Schumanniana YYarb. Warburg 
(Monsunia 1: t. 10) figures both these species and shows their leaves to 
be more spreading than in .1. Klinkii Lauterb. In the field, on the general 
appearance of the branchlets. these three trees certainly resemble members 
of the section Colymbka more than Eutacta, but in the more essential 
features, the character of the seed and scale, and the method of germina- 
tion, they definitely agree with the section Eutacta. The description of 
Eutacta could be amended to include these New Guinea species, but it 
seems preferable to propose a new section to include them.

three represent forms of one rather variable species. The two former are 
unfortunately known only from the type localities.

INTRODUCTION 



Jack described in 1822 i Mai. Mi-i\ 2: St) a new genus Psilobium 
based on two species discovered by him during his travels in Benkulen. 
The specimens which served for the descriptions have been lost. As the 
descriptions are rather short and give no measurements, it appears almost 
impossible to identify these plants. At least, as long as we are not 
absolutely sure that in this region not more than two species belonging 
to this genus occur, there can be little hope. 

The genus was characterized in this way:

Calyx patens, 5-partitus. Corolla tubo brevi, limbo 5-partito. Stamina 
basi corollae inserta. Stigma clavatum. 10-alatum. exsertum. Fructus 
cylindricus, siliquaeformis. foliolis calycinis persistentibus coronatus, 
bilocularis, polyspermus. Semina duplici serie axi affixa. 

Fruticosa. pedunculis axillaribus paucifloris, aestivatione valvata." 

For the determination of its position the following points are of special 
importance: the many-seeded fruit, the valvate aestivation of the corolla- 
lobes, the insertion of the stamens at the base of the corolla-tube, the 
clavate "stigma" (in reality that part of the style is meant on which the 
pollen is temporarily deposited, and from which it is afterwards removed 
by visiting insects), and the presence in each of the ovary-cells of two 
parallel axial placentas. The many-seeded fruit and the valvate aestiva- 
tion of the corolla-lobes, it is true, appear in a large number of genera. 
but the other characters are much more exclusive; in fact, there are but 



262 JOl KWI. OF TI1K ARNOLD ARBORKTIM [vol. xxvm 

two other genera in wliit h the whole set lias been observed. These genera 
are: Arranthrra Am. e\ Meisn. and the very imperfectly known Gonyanrra 
Khs.. the first based on a Ceylonese plant, the latter, like Psilohium. on a 
Sumatran plant. 

It may be that Arnolt when he described his new genus Arranthrra, was 
not aware of the existence of Psilohium Jac k. but il is also possible that he 
overrated the importance of the differences between the species on which 
his own and Jack's generic diagnoses have been based. The latter concern 
the position of the inllorescences. the presence or absence of a disk, and 
the structure of the ovary and fruit. The inflorescence of the Ceylon 
plant is found between the upper leaves, its disk is large and bulbous, and 
its ovary and fruit are according to Arnolt "pseudo-bilocular," i.e. pro- 
vided with an incomplete septum. In the Sumatran plants, on the other 
hand, the inllorescences have been described as axillary. The presence of 
a disk is not mentioned in Jack's description, and we may therefore assume 
that this organ is either absent or inconspicuous, and the ovary and fruit 
apparently are completely bilocular. The difference in the structure of 
the ovary and fruit afterwards proved to be untrue, for the median rent 
observed by Arnott in the septum, was, as Stapf fin Trans. Linn. Soc. 
II. 4: 173. 1894) pointed out, due to rough handling. All the same, it 
does not appear that Arnott attached much value to this character, for 
the supposed incompleteness of the septum did not withhold him from 
considering Acranthcra a near ally of Mussarnda L.. in which the septum 
certainly can not be regarded as imperfect. The two other points of 
difference are, as 1 will show further on. real enough, and might be con- 
sidered a sufficient base for generic distinction. The authors, however, who 
subsequently occupied themselves either with Psilohium or Arrant firm, did 
not see them in this light, for they indiscriminately referred to each of 
these genera species with or without a disk and with the inllorescences at 
the end of the stem as well as with opposite inllorescences. The Suma- 
tran species of Arrant htm described by Merrill (in Papers Mich. Acad. 
Sci. I<> : 194. 1934) e.g. are, exactly like the Psilohiuw species of Jack. 
provided with opposite inllorescences, whereas Psilohium siamrnsr Ken- 
produces its inflorescence exactly like Arnott's Arranthrra species, at the 
top of the stem, and is also, like the latter, provided with a large bulbous 
disk. The explanation of this anomaly lies therein that those who occupied 
themselves with Psilohium. were insufficiently acquainted with Arranthrra. 
whereas those who described new species of the latter, gave no heed to 
the existence of Psilohium. 

As long as no specimens were available which could be referred to 
Psilohium. the position of this genus remained uncertain. It is true that 
already in 1872 a plant occurring in I'egu and denasserim had been 
described by Ivurz (in Jour. As. Soc. Bengal 41(2): 313) as Psilohium 
rapillarr. but as the aestivation of its corolla-lobes is contorted, its flowers 
dioecious, its style provided with two erec t hairy arms, and its placentation 
peltate, this obviously was a mistake; the plant can not even be considered 



19471 BREMEKAMP, ACRANTHERA 263 

a near ally. Two years later Kurz himself (in Jour. As. Soc. Bengal 
46: 189. 1874) recognized it as conspecific with the unnamed plants on 
which Hooker f. had based his genus Morindopsis. 

In 1925, i.e. more than a century after the publication of Jack's paper, 
for the first time a plant was referred to 1'silobium. of which there is no 
doubt that it fits Jack's generic description. It is a specimen discovered 
bv Ridley among" the plants collected by Brooks in Benkulen. Ridley 
refers to "it in the following terms (in Kew Hull. 1925: 84. 1925): 

"Psilobium nutans Jack. Lubok Tandai, herb, in shade, common, flowers 
w hit*' green, 6681. 

I take this to be the long-lost Psilobium of Jack, obtained at Bencoolen. 
It agrees in almost all points with the description, but the calyx-lobes are 
described by him as -very large - ' which though they are fair size, hardly 
agrees with this." 

I have not been able to study this specimen, and the data given by 
Ridley certainly do not prove that it really belongs to Psilobium. The 
lacking evidence, however, has been supplied by Kerr in the description 
of his Ps. siammsc (in Hooker's Ic. PI. 34: t. 3M2. 1937). This species 
namely is said to differ from the plant collected by Brooks in the larger 
size of the flowers, the narrower calyx-lobes, the included sexual organs 
and the terminal position of the inflorescence, and must be assumed, there- 
fore, to resemble the latter in all other points mentioned in his description. 
As the fruits of Ps. siamcnsr are described as many-seeded, the aestivation 
of its corolla-lobes as valvate, the stamens as inserted at the base of the 
corolla-tube, the style as clavate, and the placentas as paired and axial, 
the set of characters by winch the taxonomic position of the genus is 
determined, must be present in Brook's specimen too. 

Although it can. therefore, hardly be doubted thai the plant collected by 
Brooks fits Jack's generic description, it can not be admitted that it is 
conspecific with Ps. nutans, the type-species of Jack's genus. According 
to Ridley's own remarks it does not fully agree with the description but 
merely "in almost all points," its calyx-lobes notably not being "very 
large" but of "fair size" only. Ridley's identification, therefore, can not 
be accepted. The specimen collected by Brooks probably represents a 
different, although doubtless nearly related, species. 

The taxonomic position of Ps. siammsc Kerr is clearly indicated by the 
lengthened internodes, the terminal inflorescence, the halfway united fila- 
ments and the large disk, for there is but one other species known so far 
in which these characters appear. This is Acranthera tomentosa R.Br, ex 
Hook.f., a plant occurring in Assam. 

The preceding expose shows thai the genera Psilobium Jack and 
Acranthera Am. ex Mei>n. are undoubtedly identical, and as the first dates 
from 1822, and the latter from 1S.>S. the name Acranthera should, accord- 
ing to the priority rule, be rejected in favour of Psilobium. This change, 
however, could hardly be welcomed. Tn the first place, as neither of the 
species described by Jack could be rediscovered, there is as yet no type 



264 JOURNAL OF THK ARNOLD ARBORLTLM [vol. xxvm 

to which the name Psilobium can be attached, and now that the importance 
of immutable types for the stabilisation of our nomenclature is generally 
recognized, this will doubtless be felt as a serious drawback. In the 
second place the change would cause a considerable amount of renaming, 
for 24 species of Acranthera would have to be transferred to Psilobium. 
If, on the other hand, the name Acranthera is conserved, but one species, 
namely Psilobium siamni.se Kerr, has to change its name, for, as stated 
above, there is very little chance that, for a long time to come, the two 
species described by Jack will be identified. There is, therefore, in my 
opinion, sufficient reason for conserving the name Acranthera. 

In a paper published in 1851 Korthals (in Ned. Kruidk. Arch. 2(2): 
183) proposed a new genus Gonyanera. which is described as follows: 

"Calycis tubus cum ovario connatus, elongatus, subpentagonus; limbus 
patens, quinquepartitus, partes ovatae acutae. Corollae tubus brevis. 
limbus 5-partitus, partes aestivatione valvata. Stamina 5, exserta, tubo 
corollae affixa; fdamenta brevia; antherae conniventes, lineares, acutae. 
Stigma elongato-clavatum; stylus teres, glaber. Ovarium elongatum, 
angulatum, biloculare. Ovula numerosa, in platen t is cylindricis laminae 
ope dissepimento affixis. Fructus haccatus. I.ilocularis; semina numerosa. 
minuta, compressa. 

Arbuscula, ramulis teretibus. Folia opposita. longe petiolata, elliptica. 
Stipulae vaginantes. Flores axillares, bracteati." 

In a remark added to the description Korthals declares that his new 
genus accedes to Psilobium in the form of the fruit, but that it differs from 
the latter in the flower-characters. A comparison of the two generic 
descriptions, however, fails to hear this out; they agree, in fact, even in 
minor details. That no mention is made of the genus Acranthera. prob- 
ably finds its explanation in the circumstance that the description of the 
latter was unknown to him; his paper, namely, although printed in 1851, 
was written at about the same time- at which the latter was published. 

Although the description of the flower contains nothing which could 
stand in the way of an identification of Korthals's minis with Acranthera, 
some doubt might be raised by the description of its habit. It is said to 
be a small tree provided with terete branches. This is rather inconvenient, 
for the species of Acranthera are all unhranched plants with obtusely 
quadrangular stems. It is possible, however, that Korthals possessed no 
field-notes with regard to the habit of the plant, and as several years will 
have passed between the date of collection (Korthals visited Sumatra, 
where the plant was collected, in the years 1833-1835) and the date of 
description, his memory may have deceived him. He may accordingly 
have mistaken the stem for a branch. It is, of course, not impossible 
that the latter may have been somewhat more rounded than is usual in 
this genus, but as his specimens are lost, this supposition can not be 

The generic name itself might also offer some difficulty. It would mean 
(cf. Backer, Verkl. Woordenb. Wei. I'lantennamen, (iron. 240. 1937) "pro- 



19471 BREMEKAMP, ACRANTHERA 265 

vided with geniculate anthers"; in Acranthera, however, the stamens are 
perfectly straight. To account for this difficulty, I think that the name 
is misspelt, and that it should be "Gonianrra": in that case it might be 
translated as "provided with an angular androecium." As the connective 
in the Sumatran species of Acranthera is strongly keeled, that would be 
verv appropriate. 

An entirely different view of the taxonomic position of Gotiyanrra was 
brought forward by Miquel (in Ann. Mus. Bot. Lugd.-Bat. 4: 262. 1869). 
He suggested that it might be identical with his own genus Gardeniopsis 
(I.e. 250), but this obviously is a wild shot, for Gardeniopsis with its 
axillary flowers, imbricate aestivation of the corolla-lobes and uni-ovular 
ovary-cells, clearly belongs to an entirely different circle of affinity. Its 
position is uncertain; it is even by no means sure that it is a Rubiacea. 
Miquel says that Blume regarded it as a Rhizophoracea, an opinion which 
deserves more attention than it has received so far. As our specimens are 
not provided with flowers, I have not been able to solve this problem. 

As the specimens on which the description of Gonyanera was based are 
lost, and as the tvpe-species. G. glauca Khs.. itself has not been described, 
there is little hope that the identity of this species will ever be recognized. 
In the exsertion of the sexual organs it resembles the two species described 
bv Jack and the plant collected by Brooks. In Acranthera longipes Merr., 
the only Sumatran species of which flowers were available to me, I found 
the sexual organs included. 

B. HISTORY OF THE GENUS ACRANTHERA ARN. EX MEISN. 
The description of Acranthera was sent in January 1838 by Arnott to 
Meisner, who used it in the compilation of his survey of the Rubiaceae. 
The latter appeared in the same year in his "Plantarum Vascularum 
Genera" (1: 162). From a note on the genus Acranthera on p. 115 of the 
second volume, whose successive parts were probably issued simultaneously 
with the corresponding parts of the first volume, on which they form a 
running commentary. 1 infer that the name of the species had already been 
published as a "nomen nudum" in Wight's "Catalogus." The note reads: 
"72. (16.) Acranthera. Arnott mss. in litt. d. 30 Jan. 1838. ad nos dat. 
— Sp. 1: A. Ceylanica. Am. in Wight cat. n. 2472. — Genus Mussaendae 
proximum, sed chanu teribus pluribus et tota facie diversum, ex auct." 
The number 72 indicates the place assigned to Acranthera among the 
genera belonging to the Rubiaceae; (16.) that among those referred by 
Meisner to the tribe "Gardeniaceae." The spelling of the specific epithet 
with a c instead of a z, as subsequently became customary, deserves our 
attention, as it evidently has precedence. The remark on the affinity of 
the new genus with Mu'ssacnda L. is noteworthy, because it shows that the 
idea of a very close relation between these two genera, which up to this 
moment has never been questioned, originated with Arnott himself. In 
the following year Arnott's description appeared in the "Annals of Natural 



266 JOURNAL OF THF. AKMH I) \lilU)KI Tl M hoc xxviii 

History" (3: 20). and was repeated by Kndlicher in his '-Genera 
Plantarum" (p. 1394). 

Arnotfs description is excellent. Apart from the fact that he mistook 
the papuliferous upper portion of the style on which the pollen is only 
temporarily deposited, for the stigma, an error which had also been com- 
mitted by Jack, and which at that time was comprehensible enough, it 
contains but a single objectionable statement. This concerns the descrip- 
tion of the ovary and fruit. Meisner (I'l. Vase. (Jen. 1: 162) says of the 
latter that it is "sicut germen pseudo-2 -loc. septo medio interr.upto 
utrinque placentam divaricato-2-lamellatam gerente," and the first is 
described in his own words (in Ann. Nat, Hist. 3: 20. 1839) as "pseudo- 
biloculare, dissepiment is duohus oppositis. vix ad medium attingentibus, 
placentam bilamellatam divaricatam ferentibus." Beddome ( Ic. PI. Ind. 
Or. 1: 5. 1874) and Hooker f. (in Benth. et Hook.!'.. Gen. PI. 2: 04. 1S73 
et Fl. Brit. Ind. 3:92. 1880) accepted this statement as essentially cor- 
rect, and described the ovary accordingly as unilocular and the placenta- 
tion as parietal, but Stapf (in Trans. Linn. Soc. Bot. II. 1: 172. 1894) 
pointed out that both ovary and fruit are perfectly bilocular. They may, 
however, easily be mistaken for unilocular, because the dissepiment is 
rather thin in the middle and. therefore, is easily torn when the razor. 
with which the sections are made, is not sufficiently sharp. 

The (Vylonese plant on which the genus was founded, shows, as Arnott 
already had noticed, a rather remarkable resemblance, especially in habit 
but also in the aspect of the fruits, to some species belonging to the 
Cyrtandreae (Gesneriaceae). This applies also to most of the species 
which since then have been discovered. As a matter of fact, I myself 
found two of my new ones (.1. Ruttrnii Brem. and .!. mc^ap/tvlla Brem.) 
among the unnamed species of Cyrtandra preserved in the I'trecht and 
Leiden herbaria, and some of those described by Valeton too had pro- 
visionally been referred to that genus. The resemblance, nevertheless, is 
but superficial, and even without looking at the (lowers, the two genera 
are always easily distinguishable, for the leaves of Acranthcra are never, 
like those of Cyrtandra, dentate, and they are always surrounded by a thin 
margin covered with stiff hairs; stipules or their cicatrices are always 
present in Acranthera and in Cyrtandra as constantly absent; and the 
fruits of Arrant/irra are always crowned b\ the persistent calyx, whereas 
in those of Cyrtandra the calyx, of course, is found at the base. 

Up to 1872 the genus remained monotypic, but in that year Kurz (in 
Jour. As. Soc. Bengal, 41(2): 312) referred to it a Tenasserim plant 
which had been described by Don (Gen. Syst. 3:401. 1S34) under the 
name Mussarnda nniflora Wall. As it differs from the typical representa- 
tives of the genus Mussarnda L. in its small size and in the absence of the 
enlarged calyx-lobes Kurz transferred it to Acranthera, which lie regarded, 
on the authority of Arnott, as a nearly related genus. This transfer was 
doubtless a change for the worse, for the Tenasserim plant has many more 
characters in common with Mussarnda than with Acranthcra: its stipules, 



1947] BREMEKAMP, ACRANTHERA 267 

exactly as in Mussaenda, are deeply bind, the flowers show the same form 
of heterostyly combined with dioecism which is found in that genus, the 
inside of the corolla-tube is not entirely glabrous but in the upper half 
covered with the same kind of yellow hairs as that of Mussaenda, the 
stamens are not inserted at the base of the corolla-tube but in or somewhat 
above the middle, the style ends in two filiform stigmas, and the placentas 
are peltate. The absence of the enlarged calyx-lobes, of course, can not 
be adduced as an argument in favour of a near affinity with Acranthera, 
as the latter is certainly not the only genus in which none of the calyx- 
lobes is enlarged, and as its mode of vegetative propagation by means of 
stolons is never met with in Acranthera, there is no appreciable similarity 
in habit Hooker f. (Fl. Brit. Ind. 3: 86. 1880) referred this species back 
to Mussaenda, but I could show (in Blumea, Suppl. 1: 118. 1937) that it 
is conspecific with the type-species of Aphaenandra Miq., a genus which 
deserves to be kept up. 

Two years after Kurz's abortive attempt to widen the scope of the genus, 
the generic isolation of the type-species was definitely broken by the 
description of two new species by Beddome (Ic. PI. Ind. Or. 1: 5. 1874). 
Both had been collected in the Western Ghats. At the same time of all 
three species figures were given (I.e. t. 23-25), but the details of the 
latter are, unfortunately, of rather doubtful value. 

Hooker f. (Fl. Brit. Ind. 3: 92. 1880) brought the number of species 
to six, but of the three new ones, A. tomentosa R.Br, ex Hook.f. alone may 
be considered congeneric; the two others. .1. Griffithii Hook.f. and A. 
Maingayi Hook.f., show the same kind of stipules, the same form of 
heterostyly combined with dioecism, the same covering with yellow hairs 
in the upper part of the corolla-tube, the same insertion of the stamens 
midway in the corolla-tube, the same kind of stigmas and the same form 
of placentation as the Tenasserim plant which Kurz had referred to this 
genus, but which Hooker himself had excluded: they belong, like the latter, 
to the circle of affinity of Mussaenda. From the typical representatives 
of that genus they differ in habit, in the complete absence of the enlarged 
calyx-lobes, and in the large size and brilliant orange or scarlet colour of 
the corolla. Stapf (I.e. 173) referred them to a subgenus Asemanthia, 
which Ridley (in Kew Bull. 1939: 600. 1939) rightly raised to generic 
rank. Acranthera tomentosa R.Br, ex Hook.f. (Androtropis tomentosa 
R.Br, in Wall., Cat. n. S39S. nomen), on the other hand, is a true represen- 
tative of the genus, although apparently no near ally of the species found 
in Ceylon and in the Indian Peninsula, from which it differs conspicuously 
in the greater length of the internodes, the larger size of the flowers and 
the halfway united filaments. The flower-colour and details of the struc- 
ture of the fruit and seeds are still wanting. A near ally was recently 
discovered in Peninsular Siam: it is the plant described by Kerr under the 
name !'si/obii<in siamcuse (see above). 

The attitude taken up by Baillon (Hist. PI. 7:319, 449. 1880) was 
logically more consistent than that of Hooker, for recognizing that the 



268 .MM liWL OF THE ARNOLD ARBORETUM [vol. xxvm 

genus Acranthcra in the hitter's delimitation contained species which 
showed a nearer affinity to Mitssacnda than to those for which the genus 
originally was created. He transferred the whole group to Mitssacnda. 
The other way out of the difficulty, the purging of the genus of the ex- 
traneous elements, however, would have deserved preference. As I will 
show further on, the true representatives of the genus are by no means 
nearly related to Mitssacnda. 

Hooker I.e. had already mentioned the presence of species of Acranthcra 
in Borneo, but as the genus in his delimitation included Ascmanthia Ridl.. 
and as both genera have since been found in Borneo, it is impossible to 
say whether the species he had in mind really belonged to Acranthcra. 

Stapf I.e. was the first to describe a Bornean species, and he too 
mentions the presence of undescribed Bornean species in the collection of 
the Kew Herbarium. After pointing out that the ovary of Acranthcra is 
always bilocular. he proceeds: "Nevertheless, I think, Acranthera must 
be retained as a well-marked genus alter excluding 1. Maingayi and .1. 
Griffithii. It may be characterized by the herbaceous growth, the gener- 
ally elongated ovary and fruit, the blue or reddish, upwards widened and 
funnel-shaped or campanulate corolla and the club-shaped, entire style. 
It is known from Ceylon, the Tinnevelly and Anamally Hills, the Khasia 
Hills, Cachar and Manipur, and there are several species, still undescribed. 
in the Kew Herbarium, from Borneo. " Although the really important 
characters, the absence of hairs on the inside of the corolla, the insertion 
of the stamens at the hitter's base, the way in which the anthers enclose 
the style and in which they are connected with it by means of the tips 
of their connectives, the way in which the upper part of the style functions 
as a temporary depository for the pollen, the subulate or semi-conical, 
often totally cohering stigmata, and the peculiar structure of the testa with 
its minutely punctate cells, have all been overlooked. The characters as 
they are given are not all of them general, for the corolla is by no means 
always blue or reddish, and the style not always club-shaped, the existence 
of a difference between Acranthcra and Mitssacnda is. nevertheless, clearly 
indicated. Which species Stapf meant when he said that the corolla might 
be reddish, is difficult to say. it is possible that the colour was described 
in this way on the label of one or more of the unnamed Bornean species, 
for instance on that of the plant afterwards described by Valeton under 
the name .!. invohicrata. At any rate, the flowers of the Ceylon and 
Peninsular species are blue, and those of A. tomentosa will probably, like 
those of the related A. siamensis (Kerr) Brem. n. comb. (Psilobium 
siamense Kerr), prove to be white or nearly white. The corolla of Stapf s 
own ,1. atropcl/a, a species collected on the slopes of Mt. Kinabalu, has 
been described as "obscure cyanea." However, as the flowers of the 
Bornean species, which since then have come to light, are all either white, 
yellow, orange or red, 1 suppose that with regard to the dower-colour of 
A. atropclla some error has been committed; maybe they assume a dark 
hue in drying. 



1947] BREMEKAMP, ACRANTHERA 269 

In 1910 and 1912 Valeton (in Bot. Jahrb. 44: 550. 1910 et op. cit. 
48: 111. 1912) described three more species from Borneo, of which one, 
A. axilliflora, is said to be provided with axillary flowers. Further on I 
will show that these flowers are in reality uniflorous inflorescences, and 
that the latter are not really axillary but borne on axillary brachyblasts 
provided with a pair of rudimentary leaves. All the same this plant 
represents a type which is quite distinct from that of the other species 
which up to that time had been recognized as belonging to this genus. In 
fact, it would probably have been more consistent if Valeton had referred 
it to Psilobium. The Acr anther a species, which at that time were known, 
produce their inflorescences at the end of the stem. Later these inflores- 
cences are forced into a lateral position by the development of the bud 
which forms the continuation of the stem. It is rather remarkable that 
the same two structural types occur side by side in another genus belonging 
to the Rubiaceae, namely in Pomazota Ridl, where some of the species 
are provided with sympodial stems and inflorescences which are at first 
terminal and afterwards solitary at the nodes, whereas in other species the 
stems are monopodial with the inflorescences opposite at the nodes, while 
a pair of scale-like leaves at the base of the peduncle prove that they are 
in reality borne on axillary brachyblasts. As stated above, it is inflores- 
cences of this kind that are found in the Sumatran group of species of 
Acranthera to which, most probably, Jack's Psilobium nutans and Ps. 
tomentosum and Korthals's Gonyanera glauca too should be referred. 

The next year Merrill described a species from the Philippines, which 
so far has remained the only representative of the genus occurring east of 
Borneo. Acranthera philippincnsis Merr. appears to be confined to the 
western part of Mindanao, i.e. to that part which by means of the Sulu 
Islands is connected with North Borneo. In this respect it is noteworthy 
that it differs in minor points only from some of the Bornean species. 

At about the same time Valeton described and figured in the "Icones 
Bogorienses" (4: 181. t. 355, 356. 1913; 4:275. t. 391-399. 1914) a 
fairly considerable number of new Bornean species. The last plate figures 
a species described under the name A. strigosa, which differs from the 
others in the shape of the stipules and in the flower-structure. The stipules 
are united in a fringed sheath, and the style is longer than the stamens and, 
if the figure is to be trusted, not provided with an apparatus serving as a 
temporary depository for the pollen. It seems, therefore, better to exclude 
this species. The form of the stipules suggests affinity with Polysolenia 
Hook.f., but as neither of Valeton's nor Hooker's species-material was 
available to me, I am unable to express a definite opinion. Acranthera 
multi flora Val. (I.e. 255, t. 396) is probably identical with A. frutcscens 
Val. (in Bot. Jahrb. 44: 551. 1910), at least the descriptions of the two 
species do not reveal differences of any importance. 

In 1934, Merrill described two apparently nearly related species from 
Sumatra. As no flowers were present, the descriptions are not entirely 
satisfactory. Of one of them, however, flowers have subsequently been 



270 JOl KNU. OF TIIF ARNOLD \RRORLTl \I [vol.xxv.ii 

collected, so that its posilion could definitely lie ascertained. The rela- 
tions between these plants and Jack s species o| Psilohium and Cionyaiura 
'^Uuttii Khs. have already been discussed. 

Three years later Merrill (in Mitt. Inst. Allg. Bot. Hamburg 7: 284. 
\9M) reverted once more to this genus, describing four new species from 
Southwest Borneo. One of these proved to be provided with red. another 
with orange-red flowers. 

The preceding notes show that twenty-live of the species which up to 
now have heen referred to Acnint/icni. may confidenth he regarded as true 
representatives of this genus, hut as two of them. .1. jrutcscais Yal. and 
.1. multijlora Yal., are probably conspecihc, only twenty-four are here 
admitted. To this number should be added the plant described by Ken- 
under the name Psttobium shnncnsc, the species on which the genera 
Psilobium Jack and Conynncra Khs. were based, but which, on account of 
the insufficiently detailed descriptions, arc now unidentifiable, and further 
the ten species described below. 

The specimens which I could study, belong almost all to the following 
four institutes: the "Rijksherbarium" at Leiden, the University Herbarium 
at Utrecht, the "Arnold Arboretum" and the "lnstitut fiir allgemeine 
Botanik, Hamburg." As 1 have seen but a small part of the Buitenzorg 
material and nothing at all from the collections of the Kew Herbarium and 
of the Sarawak Museum, my survey does not claim to be exhaustive. 

In the descriptive part of this paper special attention has been paid to 
the species occurring in the Malay Archipelago, all those of which material 
was available, being fully described. No exception has been made for 
species of which good descriptions were already extant, because the descrip- 
tions in a monograph should, in my opinion, all be made after the same 
pattern; this is the only way to ensure an easy comparability. 

TIIK TAXONOMIC POSITION OF TIIK OFNLS 

In the ''Introduction" to this paper I have already pointed out that 
Amott's assumption of a very close affinity between Acranthera and 
Mussanuia has up to now never been questioned. In Baillon's mind this 
belief had grown to such a firm conviction that he thought that the two 
genera might better be united. The common characters on which this 
assumption rests, are: the pluri-ovular ovary-cells, the valvate aestivation 
of the corolla-lobes, the tleshy pericarp, the a.xile placentas, the reddish 
brown seeds, and the terminal posilion and. at least partly, cymose 
.structure of the inflorescence. 

The bulk of the genera now referred to the tribes Lledyotideae and 
Mussaendeae are provided with pluri-ovular ovary-cells, show a valvate 
aestivation of the corolla-lobes, and have a.xile or nearly axile, peltate or 
.subpeltate placentas and ovoid or angular, yellowish, reddish or brown, 
more 1 or less distinctly alveolate, striate or punctate seeds. As the dis- 
tinction between these two tribes rests on the entirely artificial antithesis:

fruits dry or fruits fleshy. I have argued in my paper "On Urophyllum 
Wall. (Rubiaceae) and its nearest allies'" (in Rec. d. Lrav. hot. Neerl. 
38: 171. 1940) that it would be advisable to unite them, under the proviso, 
however, that those genera in which one or more of the characters enumer- 
ated above are missing, should be excluded. As instances of such genera 
I referred to those provided with a i la\ ate or i oh miliar placenta and smooth 
seeds. In my recently published (jour. Arnold Arb. 28: 186-203. 1947) 
''Monograph of the genus Pomazota Ridl." I give a short survey of the 
genera which for some reason or other should be excluded. Acranthera is 
not mentioned in this list, because its aberrant character is not so strongly 
marked as in the others. It is all the same by no means insignificant: its 
placentas, namely, are not peltate or subpcltate. but attached along their 
whole length to the dissepiment. It is. therefore, extremely questionable 
whether this genus may be reckoned to this circle of affinity. If it should 
be excluded, it can, of course, not be considered a near ally of Mussanula. 
which is a quite typical representative. The other points of resemblance 
between Acranthera and Mussaeiida. the fleshy fruits, the terminal posi- 
tion and. at least partially, cymose structure of the inflorescences, do not 
belong to the general characters of this large tribe, and as they appear in 
almost all the larger groups, are of little importance. The resemblance 
between the two genera, therefore, is not sufficiently comprehensive to be 
regarded as proof of their near affinity. 

A survey of the points of difference between the two genera may be 
expected to throw more light on this question. The principal ones are 
found in: the structure of the stipules, the floral mechanism, the presence 
or absence of hairs on the inside of the corolla-tube, the insertion of the 
stamens, the relation between the latter and the style, the nature of the 
stigmata, the attachment of the placentas and the structure of the testa. 
In Acranthera the stipules are simple; the flowers homostylous and herma- 
phrodite: the corolla is completely glabrous inside; the stamens are in- 
serted at the base of the tube; the anthers form a sheath around the style, 
and are connected by means of the projecting tips of the connectives with 
the top of the latter; the pollen is temporarily deposited on the upper part 
of the style, which, to that end. is covered by rows of papillae (for the 
sake of convenience this part of the style will from now on be designated 
as the "receptaculum pollinis"): from here it is removed by the visiting 
insects; the stigmata are subulate or semi conical, and do not spread, not 
rarely remaining permanently attached to each other; the placentas, as 
stated above, are attached along their whole length to the dissepiment, and 
the testa-cells are minutely but very densely pitted (Fig. 1). In Mus- 
saenda, on the other hand, the stipules are always bifid or bipartite; the 
tlowers heterostylous, the short styled ones being male and the long-styled 
ones female; the upper part of the corolla-tube is inside covered with 
yellow hairs; the stamens are inserted at or somewhat above the middle 
of the tube; there is no connection whatever between the anthers and the 
style, and the pollen is directly removed from the anthers to the stigmata;

the latter are, at least in the female llowcrs. alway> linear and spreading; 
the placentas are peltate, and the testa-cells provided with a few very large 
pits (Fig. 2). 

These differences are. of course, not all equally important. The value 
of the difference in the attachment of the placentas to the dissepiment, has 
already been discussed; il certainly justifies some doubt with regard to 
the propriety of leaving the genus At rant In > a in this tribe. The peculiar

■ i 



kind of floral mechanism is an even more weighty argument against the 
view that it should belong to this group, for in none of the general related 
either to Hcdyotis L., Urophyllum Wall., Sabicca Aubl. or Mussacnda L.. 
a style functioning as a temporary depository for the pollen is found. As 
I have pointed out in my "Monograph of the genus 1'avetta L." ( in Fedde's 
Repert. 38: 11. 1934) a style of this nature characterizes one of the main 



mm 





groups of the family, comprising the tribes Ixoreae, Gardenieae, Alberteae. 
Vanguerieae, the isolated genera Crossoptcryx Fenzl and Coptosapclta 
Khs., and perhaps part of the present tribe Naucleae. In all these plants, 
however, the anthers wither after the pollen has been deposited on the 
style, whereas the receptaculum pollinis of Acranthera remains included 
between the empty anthers, and can be reached only through the windows 
between the projecting tips of the connectives. For this reason, and also 
because the stamens are not. as in the Ixoreae and their allies, inserted 
in the corolla-throat, but at the base of the tube, it seems to me that 
Acranthera can not be related to this group either. Moreover, the connec- 
tion of the stamens by means of the projecting tips of the connectives 
with the top of the style is a feature so entirely unparalleled in the 
Rubiaceae, that one might feel inclined to regard the position of the genus 
with regard to the rest of the family, as similar to that of the Asclepiadaceae 
with regard to the Apocynaceae, although in this way the importance of the 
connection between the anthers and the style, is doubtles: \tr emj h i /c 1 
It is perhaps more readily comparable to the way in which in the genera 
Ceropegia L. and Dichaelia Harv. (Asclepiadaceae) the corolla-tips cohere. 



271 JOURNAL OF THK ARNOLD ARBORETUM [voi.xxvm 

There is one point more on which I should like to expatiate a little, 
although it does not concern a difference between Acranthcra and 
Mussacnda, for in the point I mean, the absence of raphide-cells, there is 
complete agreement between the two genera. 

With regard to the presence or absence of raphide-cells there is no 
conformity between the various groups included in my enlarged tribe 
Hedyotideae. and as all other large groups are in this respect entirely 
consistent, this is doubtless a weak point. It might be argued that 
Hcdyotis L. and its nearest allies, which are all provided with raphide- 
cells, are perhaps more closely related to the Spermacoceae and Psycho 
trieae, which they resemble in the aestivation o\ the corolla-lobes, but from 
which they differ in the pluri-ovular ovary cells, than to Sahicca Aubl., 
Urophyllum Wall, and Mussacnda L. and then respective allies, which they 
resemble, apart from the aestivation of the corolla-lobes, to some extent in 
the nature of the placentation, but in which raphides are apparently always 
wanting. A satisfactory solution of this question can not yet be given. 
For the determination of the position to be assigned to Acranthcra. this is 
not ot paramount importance, as the relations between this genus and the 
various groups in which raphides are wanting, are hardly more pronounced 
than those with I/cdvotis. 



i in m i;di\ ision ot tin: ckms 

Up to now no attempt has been made to arrange the species of 
Acranthcra in natural groups. Yaleton, who at one time (in Ic. Hog. 
■I: fasc. 4. 1914) described no less than nine new species, contented himself 
with an alphabetical arrangement! This apparently means that he had 
not been able to distinguish well-defined groups, and was of opinion that 
the best way to make the species distinguishable, was to figure them, which 
he accordingly did with as many as he could lay hands on. The result is 
that of no other rubia. eons genus of any extent has such a large percentage 
of the species been figured (of the 20 species known in 1914 e.g. no less 
than 14, i.e. 70 per cent). These efforts, however, were, I am afraid, of 
little avail, for even with the aid of the pictures the species are by no 
means easily recognizable. It was to be expected, therefore, that a more 
thorough analysis would lead to better results. On account of the fact that 
not all species were available, and also because on some points, for instance 
on the habit and on the [lower-colour, reliable information could not always 
be obtained, the results are not yet fully satisfactory; but 1 have no doubt 
that as soon as more material is forthcoming, the defects of my classifica- 
tion will easily be amended. 

It is here perhaps the most suitable place to make a few remarks on the 
two points just mentioned, the habit and the tlower-colour. 

A good deal of misapprehension has existed up to now with regard to 
the habit of these plants. On the labels they are not rarely described as 
shrubs and in one case even as a small tree (A. longipes Merr.), but these 



19471 BREMEKAMP, ACRANTHERA 275 

indications should not be taken at their face value. It is a well-known 
fact that European collectors, accustomed to the soft shoots of the herbs 
of their native countries, often take tropical herbs for shrubs, even though 
there is no sign of branching, because they arc misled by the woodiness of 
the stems. The indication '•small tree" on the label of some of the 
specimens of A. lov^ipcs Men., on the other hand, is doubtless a faulty 
translation of the "pohon ketjil" of the Malay collector. It is often 
overlooked that in Malay each plant provided with an erect stem is called 
"pohon," no matter whether it is an herb a few centimeters high and 
without a singe branch or a tree with a large crown. 

Stapf was doubtless right when he described the habit of the Acranthcra 
species as herbaceous. Among all the specimens investigated by me, but 
very few were branched, and in these few exceptions the ramification was 
always of the pseudo-dichotomous kind. They belong to species in which 
the stems normally are sympodiah This means that occasionally at the 
base of the inflorescence instead of one bud both buds develop. Even 
those species which, like A. jrutescens Val., reach a fairly considerable 
height (1.5-2 m.), apparently remain unbranched. It is not impossible 
that the larger plants require more time to complete their life-cycle than 
those that remain lower, but no reliable information with regard to this 
point seems to be available. In some species there are indications that 
the stems in the end sink down, and that innovations are produced from 
their basal parts. 

Our information with regard to the flower-colour ton is far Irom complete. 
This is all the more unfortunate as it looks as if this might be of real 
taxonomic importance. 

The three western species are blue-flowered. The flower-colour is un- 
known to me, of the Assam ,1. tonuntosa R.Br, ex Hook.f. but in the 
nearly related A. siawcnsi.s ( Kerr) litem, the (lowers are white. The first 
of the species described from Borneo, .1. atroptila Stapf, was said to be 
provided with a dark blue corolla, but, as staled above, this is probably a 
mistake. The majority of the Bornean species and the only Philippine 
one possess white or slightly tinted (lowers; in the rest of the Bornean 
species the corolla is yellow, orange or red. In these plants the calyx too 
is often coloured, not rarely in a different shade. With regard to the 
flower-colour of the Sumatran species we are insufficiently informed, but 
those of Brooks's Benkulen species, the <>ne that was identified by Ridley 
as I'silobium nutans Jack, are elated to be -reenish white. 

The characters with which we will mainly have to be content, are: the 
shape and size of the stipule-, the position and form of the inflorescences, 
the shape of the corolla-tube, the fusion or complete freedom of the basal 
parts of the stamens, the presence or absence of a fringe of cilia between 
the outer rim of the thecae and the connective, the shape of the latter, 
the presence or absence of a disk, the form of the rcccptaculum pollinis, 
the structure of the fruit and that of the testa. By the aid of these 
characters I have divided the genus in nine subgenera, of which the first, 



■21h JObKNAI. OF T1IK AKNOI.I) \ K H< >K III M fvoi.. xxvm 

Eu-acranthcra, is confined to Ceylon and the Indian IVninsula, the second, 
Androtropis, to Assam and Peninsular Siam, the fourth. Am photcrosanthns, 
to Sumatra, and the others to Borneo, except the eighth. Mitracmc, which 
contains, besides some Hornean species, the only representative of the 
genus found in the Philippines. 

Eu-acranthcra and Androtropis differ from all the other subgenera by 
the presence of a well developed disk. In Eu-acranthera, moreover, the 
corolla is blue and its tube begins with a cylindrical part, which widens in 
the upper half to funnel-shape, whereas in the other subgenera the corolla 
is presumably never blue, and its tube is either entirely funnel-shaped or. 
more often, narrowly campanulate. Androtropis differs from the other 
subgenera in the presence of a staminal tube formed by the basal hakes 
of the filaments; in all other subgenera the filaments are entirely free. 

The third subgenus. Clromoi arpus. differs from the other subgenera in 
the structure of the fruits, which are narrowly cylindrical and marginate, 
the hardened margin remaining after the seeds have been shed, in the form 
of a "replum." The latter, however, is morphologically not equivalent to 
the replum of the herbaceous Capparidaceae, the Cruciferae and Chcli- 
donium, for in these plants the rim is formed by the fused margins of the 
carpels, whereas in the subgenus ( 'Iconnn urpits of the genus Acranthcra 
it represents the midribs of the carpels. The dissepiment, accordingly, 
is not. as in the Cruciferae. attached to the nm, but stands at right angles 
with it; in the end the dissepiment disappears with the valves. The 
stipules of Cleomocarpus are smaller than those found in any other sub- 
genus; in shape, however, they are not unlike those of the subgenera 
Eu-acranthcra, Androtropis and Am phot crosant hits. Its two species are 
nearly glabrous plants with densely reticulated leaves. 

The fourth subgenus. Am photi rosant hus, is confined to Sumatra and 
the neighbouring island Simalur. It resembles the three preceding sub- 
genera in the triangular shape of the stipules, but differs from them in the 
position of the inflorescences, which are borne on opposite brachyblasts 
provided with a pair <>\ rudimentary leaves. The inflorescences themselves 
are few-flowered. In position and structure they are similar to those 
found in some species belonging to the subgenus Pi< hroanthes and to 
those of Ablepharidesma. The seeds are reticulate, whereas in almost all 
other species of which ripe fruits were available, the seeds were found to 
be either distinctly carunculate or nearly smooth. There is. however, no 
difference of fundameiit.il importance between the various kinds of seed. 
The two species of I'silobium. described In Jack, and (ionyancra "lanca 
Khs. belong probably to this subgenus. As no specimens are extant, and 
as the plants are not identifiable from the descriptions, it did not seem 
advisable to retain either of these names for the denomination of the 
subgenus. 

In \he other subgenera the stipules are wider and longer than in the 
preceding ones, and of an entirely different shape, namely ovate, elliptic or 
oblong. The differences between these subgenera are not so striking as 



i"i: I 



|!i;i Ml k\MI\ \CR\NTIIF.H 



those between the former. They are mainly confined to the position and 
structure of the inflorescence, the shape of the rcceptaculum pollinis and 
the presence or absence of a fringe of cilia between the thecae and the 
connective. Athroophlcps, however, is well characterized by the peculiar 
nature of the reticulation. It is noteworthy that with regard to the shape 
of the rcceptaculum pollinis and to the presence or absence of a fringe of 
cilia along the connective, the first four subgenera. Eu-acranthera. 
Androtropis, Clcomocarpus and Amphoterosauthus. show a uniform char- 
acter: their anthers are always eciliolate, and the rcceptaculum pollnm is 
everywhere fusiform, and of about the same length as the thecae. 

In the three subgenera 1'hanero, hi/on. Pit hroanthes and Ahlephandcsma 
too the rcceptaculum pollinis is of about the same length as the thecae. 
and either fusiform or cylindrical. In Phanerochiton and Dichroanthes 
the anthers are ciliolate. in Ahlepharidcsma eciliolate. The monotypic 
subgenus Phanerochiton differs from the two others in the long, scarious 
stipules, the trichotomous inflorescence with its large bracts and the 
thick-walled fruit, and from all other representatives of the genus in the 
presence of dark-coloured resin-cells on the upper side of the leaves. In 
Dichroanthes the filament, are about as long as the anthers, the rccepta- 
culum pollinis cylindrical, and the flowers often, perhaps even always, 
gaily coloured, the corolla yellow, orange or red. and the calyx white or m 
a different shade of orange or red. In the other Bornean species the 
filaments are alwavs much shorter than the anthers, and the corolla is 
apparently everywhere either white or but slightly tinted. Dichroanthes 
is divided in two series, one with terminal inflorescences and cohering 
stigmata, the other with inflorescences borne on opposite brachyblasts and 
with free stigmata. In Ablepharidesma the inflorescences are few-flowered 
and borne on opposite brachyblasts. the anthers eciliolate. the shoots thin, 
and the leaves and stipules small. 

In the subgenus Mitracmc the reccpta, ulum pollinis is much shorter 
than the thecae and mitriform, i.e. the papillae arc reclinate and increase 
from the top towards the base of the rcceptaculum gradually in length. 
In this subgenus I distinguish four series. In the first series the anthers 
are ciliolate, whereas in the other three they are always eciliolate; the 
species belonging to this series are robust plants with large trichotomous 
inflorescences provided with large brads. The second scries is monotypic. 
the only species being the Philippine I. philippiuensis Men.; it is a low 
plant with a trichotomous inflorescence provided with well-developed 
bracts. The third series is also monotypic, the only species being a 
narrow-leaved plant with few-flowered inflorescence and small bracts. 
The fourth series comprises plants with umbelliform inflorescence, in 
habit not unlike some of the species belonging to the subgenus 
Dichroanthes. 

The last subgenus. Athroophleps, is a small but very natural group. 
confined to North Borneo and easily recognizable by the peculiar arrange- 
ment of the thick-set prominulous venules, which form narrow meshes.

arrangement was noticed already h\ Valeton (cf. Ic. Hog. 4: 27(> (line 6).

stretched in this direct ion. and except in C/romocarpus, where the reticula- 
tion, however, is very faint, their number is always much smaller. Other 
peculiarities of this subgenus are the annular shape of the rcccptaculuni 
pollinis and the great length of the points in which the connectives are

5. Aerantliera sianiensis (Ken) Brem. n. comb. ^ ^ 

I'silobium siamoise Kerr in Hook., Ic. PI. t. 3332. 1937. — Peninsular Siam. 

Of 1 tomentosa 1 had but a single, not very good, specimen, whose 
(lowers were much larger than those of the specimens described by Hooker. 
Fruits of this species were not available to me. 

For I siamensis 1 relied on the detailed description given by Kerr and 
on the excellent plate bv which the latter is accompanied. Kerr referred 
this species to Psjlohium lack, because it rcseml.le> the specimen collected 
by Brooks in Benkulen. which Ridley (in Kew Hull. 1925: 84. 1925) had 
identified as I's. nutans Jack, but which is probably a different species 
(see above). The near affinity between the Siamese plant and A. tomen- 
tosa R.B'r. ex Hook.f. was overlooked by the author. 

Kerr ends his description with the following remark: "It seems 
probable, judging from a cursory examination, thai some plants assigned 
to Gardenia Section Gardeniella. should rather be referred to I'silobium. 

The section Gardeniella was created by Ridley (Fl. Mai. Pen. 2: 80. 
1923), who referred to it four species from the Malay Peninsula, which 
show but little resemblance to the typical representatives of the genus 
Gardenia. The possibility that they might belong to Aeranthera. of which 
representatives are found both to the North and to the South of the Malay 
Peninsula, certainly deserves our attention. Judging from the somewhat 



282 JOUtXAI. OK INK \B.\OI.I) \K BOKITI M |\ni..x\\ni 

meagre descriptions, 1 do not believe however that anyone of them ran be 
transferred to this genus. The first, G. taitaculata Hook.f. is described 
by Ridley as a "bush," a habit which is entirely unknown in Acranthcra; 
its stipules, apparently, arc similar to those of .1. stri^osa Yah, a species 
which in my opinion does not belong to this genus. The three other ones 
seem to be unbranched, but they differ from all species of Acranthcra 
known so far in the position of the inflorescences: the latter, namely, are 
found on the defoliated part of the stem. In two of them, G. vircsccn.s 
Ridl. and G. pulchella Rid]., the stipules, moreover, are like those of G. 
tentaculata "fringed with long points." The last one, G. didymocarpus 
Ridl., had provisionally been referred by H. H. \Y. Pearson to Acranthcra. 
Its removal by Ridley to Gardenia evidently means that it does not fit the 
description of Acranthcra. It is possible, however, that Ridley was in- 
fluenced by the lateral position of the inflorescences.

7. Acranthera ophiorrhizoides Val. in Ic. Bor. I: 2S7, t. 397. 1014. — North Romeo. 
I am not fully certain that this species, of which no material was 
available, really belongs to Cl< ouwcarpns. It resembles .1. siliquosa in 
the nature of the stipules, the nearly glabrous leaves, the terminal in- 
florescence and the small size and white colour of the flowers. The fruits 
are imperfectly known; in Yaletoids specimens they were apparently 
immature, and with regard to the presence or absence of a replum there is, 
therefore, no certainty. The anthers have been described as bearded, and 
figured as ciliolafe. but I suppose they are neither. Yaleton's specimens 
were apparently badly preserved, and it is. therefore, quite possible that 
the presence of cilia was simulated by the mycelium of a fungus with which 
the anthers were overgrown.

As the two Psilohiuiii species of Jack and Korthals's (ionyanrra glama 
are provided with "axillary" iniloreseences or tlowers and elongated ovaries 
and fruits, there can be little doubt that they belong to this subgenus. The 
exserted sexual organs distinguish them from .1. longi pes Merr., the only 
species of which dowers were available. The description of Psilobhim 
nutans Jack says that the leaves are lanceolate and smooth, and that the 
peduncles bear three to six tlowers. whereas in J's. tomeutosum Jack the 
inflorescences are apparently unitlorous and the leaves tomentose. The 
leaves of Gonyaneni glauea Khs. are said to be elliptic and the calyx-lobes 
ovate, and the iniloreseences of this species too appear to be unitlorous. 
That these meagre indications would suffice for the identification of these 
species, seems excluded.

This species, which 1 could not investigate myself, differs from .1. 
Inu^iprs in the much shorter petioles, the smaller si/e of the leaves and 
their more conspicuously pilose underside, in the up to 1.5 cm. long 
stipules, the ovate oblong calyx-lobes and the hairy fruits. From .1. 
siiiiii/nmisis it differs in the larger size of the stipules and in the shorter 
and wider calyx-lobes. It was collected in the same region as A. longipes, 
namely in the Fast Coast Gouvernment (District I'ematang Siantar, I)k

Valeton had recognized in Achmad's specimen a new Amint/irra species. 
for which he proposed the specific epithet -mutira." but a description was 
never published. The name "mutka' has probably been used in opposi- 
tion to -Acranthera." and would mean that the anthers are blunt, but as 
this can hardly be right, I have chosen another epithet. If the name really 
referred to the shape of the anthers, it would prove that Valeton had seen 
flowers, which in the Leiden specimens were not present; the Buitenzorg 
material, therefore, would be more complete.

This species is, apart from the much denser indumentum and the 
persistent bracts, habitually not unlike .1. frutrsrens \'al.. from which it 
differs, however, in the following important points: the presence of resin- 
cells in the epidermis of the upper side of the leaf, the infundibuliform 
corolla-tube, the greater length and fusiform shape of the ncrptaatlioii 
polliuis. and the thick-walled fruit. The thick dissepiment distinguishes 
this plant from all other species of this genus of which tin- fruits are known. 
The wide range of variability in the number of nerve pairs is rather 
remarkable: it may be, observed even in one and the same specimen.

A specimen collected by the Kxpedition Xiaavenhuis near the S. Blu-u 
{541 |F|, .1. multinervia Val. in sched.) comes very near to the plant 
described above, and may be conspecitic. Its leaves, however, are less 
distinctly bullate. the hairs on the nerves are more patent, and the pedicels 
and ovaries less densely grey-strigose; that the thecae seem to be less 
distinctly ciliolate and the connective but indistinctly granulate, may lie 
due to the immaturity of the buds and their bad state of preservation. 

The inflorescence of .1. bullata ha- three main branches, but the latter 
are so short that their existence is easih overlooked. From a morphologi- 
cal point of view their presence, nevertheless, is of importance, because it 
shows that the umbelliform inflorescence of this subgenus is to be derived 
from the trichotomouslv corymbose one found in several other subgenera. 

Acranthrra bullata is easily .list inguishable by its bullate leaves. It 
comes nearest to .1. J oluuuiis-W'hiklcri Mcrr. and .1. movant ha Yal., which 
it resembles in the great lenglh ol the calyx-lobes and the infundibuliform

If we may assume that the form and structure of the fruit of this species 
is typical for the whole subgenus, the difference between the latter and the 
subgenus I'/ianerochiton becomes still more prominent. 

Acranthcra JohainiisAY inklcri resembles A. bulhita in the long calyx- 
lobes, the infundibuliform corolla-tube and the carinate and granulate 
connective, but is easily distinguishable by the smooth leaves, the smaller 
stipules, 1- or 2-llowered inflorescence, the greenish colour of the calyx- 
lobes and the orange colour of the corolla, and the greater length of the 
hitter's lobes. Acranthcra monantha Yal. is probably even more closely 
allied, but comparison is made difficult by the circumstance that we have 
no information with regard to the connective and with regard to the colour 
of calyx and corolla. On account of the very close resemblance in other 
respects, the connective will probably prove to be carinate and granulate: 
in the key to the species use has already been made oi this character.

Of this species I have seen no specimens, but judging from the descrip- 
tion there can be little doubt that it is nearly related to .1. Jo/iannis- 
Winklrri Merr. Xo information, however, is available with regard to the 
(lower-colour, tin- shape of the connective and that of the rcrrptaculum 
pollinis. The plant, moreover, is described as unisexual, but this is doubt- 
less a mistake. The type. Brrrari 31.5-1, was, according to Yaleton I.e.. 
collected in North Borneo, but as some other specimens whose numbers 
differ but slightly from that of this plant, are known to have been col- 
lected in Sarawak, 1 suppose that this is a mistake.

So far three species of Arrant hera are known to be provided with 
variegated leaves. The two others are: .1. marulata Val. and .1. IlaUierii 
Val. Aerantltera marulata also belongs to the subgenus Dirhroanthrs, 
but to the series Monopodiales; it is moreover easily distinguishable from 
.1. varirgata by its solitary dowers. Arranthrra llalliirii has a mitriform 
rrrcpiarulum pollinis, and belongs therefore to the subgenus Mitrarmr. 



19471 BREMEKAMP, ACRANTHERA 291 

It differs further from .1. variegata in the presence of 6-7 pairs of nerves in 
the leaves, the deciduous >t ipult-s. ;ind the position of the inflorescences, 
which are not found at the end of the stem, but at the end of opposite 
brachyblasts. 

The nearest ally of this species is doubtless .1. aurantiaca Val. ex Brem., 
whose leaves are longer and narrower, on the upper side strewn with a 
few hairs, and entirely green, and whose inflorescences consist of fewer 
but larger flowers. 

A peculiarity of A. varicgata not mentioned in the description, is the 
presence of a ring of cohering colleters on the inside of the calyx; it is 
produced in triangular slips between the calyx-lobes. In all other species 
the number of colleters is so much smaller that they are unable to form 
a complete ring; sometimes, however, they cohere in groups, especially in 
the gap- between the calyx-lobes.

Acrauthcra longipctiolata differs from the two preceding species in the 
unillorous inilorescences, and from the other species belonging to this 
series in the great length of the petioles and the large size of the leaves 
and stipules. 

An apparently nearly related species is represented by a specimen 
collected in Sarawak (Nat. coll. 10 jo | A A | ). Its leaves are much smaller 
(15 IS cm. X 4.5 6 cm.) attenuate at both ends, and provided with six 
instead of ten pairs of nerves; the petioles are shorter and very sparsely 
strigose, and the stipules are nearly glabrous. As flowers and fruits are 
wanting, it does not seem advisable to name it. 



The type of this species, of which no material wa< available to me. was 
collected by Hub. Winkler between Balu Labi and Lumowia in South-east 
Borneo. The description is in some important points incomplete, but in a 
note attached to the description of .1. maculaia Yal. it is stated that it 
agrees with the latter in the structure of its inllorescence and flowers, and 
that it differs from that species in the same way as .1. abbreviata Yak, viz. 
in the ovate-lanceolate instead of linear calyx lobes and in the larger size 
of the leaves with their 6 or 7 instead of 4 or 5 pairs of nerves. Although 
in the description of .1. abbreviata itself no mention is made of .1. axilH- 
flora, the affinity between these two species is apparently closer than that 
existing between .1. axilli flora and .1. maculate In fact, the only differ- 
ence between .1. axUliflora and .1. abbrcviata which could be detected by 
a comparison of the descriptions, lies in the nature of the indumentum.

Of this species too no material was available to me. Valeton I.e. states 
that it shows a "superficial" resemblance to .1. macidata Val., from which 
it should differ in the small size and deciduousness of the stipules, the 
number of pairs of nerves, the larger size of the leaf-tip and the stamens. 
The filaments, namely, are said to be slightly shorter than the anthers, but 
as the figures show that the flowers investigated by Valeton were not yet 
fully mature, this is by no means certain. It is quite possible that in the 
open flower the filaments will prove to be longer. The connective is 
described as broad and flat, but in fig. 3 it is shown as carinate, and I have 
little doubt that this is right, and that the resemblance between .1. 
hirtistipula and .1. macidata. therefore, is not merely -.superficial;' but that 
the two species are nearly allied. By the aid of the characters given in 
the key they will, nevertheless, prove easily distinguishable.

Of this species too I have seen no material. The Buitenzorg herbarium 

apparentlv possesses a large number of specimens, all collected during the 
Expedition Xieuwenhuis in Central Borneo. Of one of the specimens the 
flowers are said to be white, but the colour of the others is not mentioned. 
The white colour, however, may be a mistake. Figure 8 represents a 
fruit which is said to belong to this species, but this apparently is wrong, 
for it is more or less rostrate and lacks the persistent calyx: it might 
pertain to a Cvrtandra. It is possible, therefore, that one of Valeton's 
specimens was mis-identified, and the white flowers might belong to this 

Valeton's figure gives the impression that the uppermost flower is 
terminal, and the others solitary at the nodes: if this were so, this species 
could not belong to the series Monopodiales. As the description, however, 
makes no mention of a terminal flower, and as the bifid stigma points in 
the direction of the species with opposite inflorescences, the impression 
created by the figure is probably wrong.

The description given above has mainly been based on Kndert's specimen. 
It deviates in the following points from the original one. given by Valeton: 
the number of pairs of nerves is 11 or 12. not 16; the bracts are slightly 
smaller (6-10 mm. X 3.5-6 mm. instead of 13 mm. X 8 mm.) and the 
calyx-lobes too are smaller (6 mm. X 3-3.5 mm. instead of 8 mm. X 5 
mm.). The difference in the number of pairs of nerves is probably uncer- 
tain. As a comparison of Yaleton's descriptions with the accompanying 
figures in the Icones Bogorienses prove, all nerves springing from the 
midrib were counted by him as primary ones, whereas 1 rest rid the term 
to those which art' readily comparable, leaving out the weaker nerves 
inserted in the intervals between the stronger ones. The differences in 
size of the bracts and the calyx-lobes offer a more serious difficulty, but 
these dimensions are probably rather variable. 

Acranthera multipara Val. in Ic. Hog. 1: 286, t. 396. 1914, is probably 
conspecific. The details of the flower-structure given by Valeton. are not 
to be trusted. I have little doubt that his flowers were both too young 
and badly preserved, and Valeton himself, as the remarks at the end of his 
description prove, attached no value to these details. In the Sarawak 
specimens quoted above, which agree well with Yaleton's figure, the thecae 
are ciliolate and the rcccptaculum pollinh milriform. The most important 
difference lies in the greater length of the fruits, which are said to be 
2 cm. long. It is, of course, possible that a comparison of the authentic 
specimens will reveal the presence of differences not mentioned in the 
description, and that more than one species will have to be recognized, but. 
for the present I prefer to consider them conspecific. 

Elmer 20S3S, collected near Tawao in British North Borneo, and re- 
ferred by Merrill I.e. to .1. jrutcscens. differs in the size of the leaves and 
in the fewer nerves. It resembles in these characters .1. vclutincrvia, from 
which it differs in the nature of the indumentum and above all by the 
short fruits, which are more like those of .1. jrutcscens. It is doubtless 
an undescribed species, but as there were no flowers in the specimens which 
I could investigate, I am unwilling to describe it. As the flowers are 
described by Elmer as pale green, it is very probable that they will have 
been preserved at least in some of his specimens.

The description given above has been based on the specimen collected 
by llavilaud <r llnsr. but agrees in all essential points with that given by 
Yaleton. The latter saws of the inilorescences "vulgo tres in apice caulis 
umbellatae," but this is doubtless a mistake, lor inilorescences arranged in 
this way are entirely unknown in this genus; the short common peduncle 
has apparently been overlooked. The rrcrptarulum pollinis, which he in 
the usual way takes for the stigma, is accurately described as "eonicum 
acutum." but badly represented in fig. (>, where it shows an ovoid shape. 

This species is easily recognizable among all its allies by the narrowly

Acranthcra X ianc< nhuisii comes very near to .1. Ilallicrii Val., from 
which it differs in the greater length of the internodes, the lanceolate, 
entirely green, less conspicuously ciliated leaves, the oblong stipules, the 
linear calyx-lobes and the greater length of the points in which the con- 
nectives are drawn out. Both species are in general aspect not unlike 
some species belonging to the subgenus Dichroanthes, namely A . varicgata 
Merr. and A. aurantiaca Yal. ex Brem., from which they are, of course, 
easily distinguishable by the eciliolate anthers and the mitriform recep- 
taculum pollinis, and probably also by the colour of the corolla. It is true 
that the colour of the corolla in I. Xicuia uhuisii is unknown, but as that 
of A. Ilallicrii is said to be white, there is good reason to assume that the 
flowers of A. Nieuwenhuisii too will be white.

Specimens of this species were collected by Low & Ilaviland on tin- 
slopes of ML Kinabalu at an altitude of 1500-1800 m. It reaches, there- 
fore, a greater height than any of its allies. Its position in the subgenus 
Mitracme is not yet fully assured, for Stapf describes the receptaculum 
pollinis, which he too confuses with the stigma, as capitate, but as his 
description in other respects closely resembles those given above of .1. 
Xiciavcnhuisii and .1. I/allicrii. 1 have little doubt that its receptaculum 
pollinis is in reality mitriform. The corolla has been described as "obscure 
cyaneum," but this may be the colour it assumes in the herbarium: the 
flowers of the other Bornean species are, at least in the living state, never 
blue. The similarity between this species and .1. Hal/ierii has been noticed 
already by Valeton, who. however, gave an erroneous interpretation of the 
structure of their inllorescences (cf. Ic. Bog. 4: 182. 1913). He thought 
that the flowers were in reality axillary, the umbellate arrangement being 
simulated by the shortness of the upper internodes. but in .1. Uallierii the 
flowers are by no means subtended by ordinary leaves, but by minute 
bracts, and the inflorescence is doubtless cymoso-umbellate. Stapf de- 
scribes the flowers of A. atropella as ■pseudo-umbellate," but this means 
probably that the flowers do not open centripetally. as in a true umbel, 
but centrifugally. As he says that the inflorescence is sessile and at the 
base surrounded by the two upper pairs of leaves with their stipules, the 
possibility that the flowers might be axillary, seems excluded. True um- 
bels are probably unknown in the whole family; when the flowers are 
fascicled at the top of a common peduncle, the arrangement always seems 
to lie entirely or partly cymose. 

Stapf mentions a minute white punctation of the upper side of the 
leaves caused by collapsed cells. This punctation has also been observed 
in .1. .Xiciavcnhuisii and in the I luce spec ies belonging to the next subgenus.

[n the colour which it assumes in drying, and in the presence of 

collapsed cells on the upper side of the leaves, this species resembles 
.!. atropclla Stapf, from which it differs, however, conspicuously in its 
almost complete glabrescence. in the larger size of the leaves and stipules, 
and above all in the paniculately arranged, subsessile llowers. As Stapf 
states that in his species the venules are indistinct, the possibility that it 
might belong to the subgenus At/iroof>Mrps. need not be taken seriously. 

Tin- differences between this species and the two next ones have been

TROPICAL FERN HOSTS OF RIST VI \G 
J. H. Faull 



Rusts on ferns are referred in current literature on mycology and 
plant pathology to the definitive genera Ilyalopsora, Milcsia, Urcdinopsis. 
Dcsmella and Puccinia and in a few instances to the imperfect genus 
Uredo. The complete life-histories of many species of the first three have 
already been determined experimentally; in all cases they have proved to 
be heteroecious, with species of Abies serving exclusively as their aecial 
hosts. So it may quite safely he assumed thai the same pattern is poten- 
tially true of all the other species of II yalopsora. Milesia and Urcdinopsis. 
Regarding Dcsmella. uredia and telia only are known; and as they are so 
unlike those of the three foregoing genera, the identities of hosts that can 
carry the aecial stages of Dcsmella rusts are not even conjectured. It is 
a strange genus, taxonomically standing quite apart from the other fern- 
restricted genera. Thus far it has been reported from the American 
tropics only. Among the remaining fern rusts, a single species of Puccinia 
has been described, though solely with respect to its uredia and telia. 
Finally, as to the [/redo fern rusts, they can with reasonable certainty be 
recognized as uredo stages of one or other of the five definitive genera. 
Indeed, not a few of the named species of these genera have been described 
from the uredo stage and without knowledge of telia. All hough technically 
open to some objections, this practice does offer advantages if used with 

With possible exceptions of Australia and Tasmania, fern rusts are 
world-wide in distribution. Of course, locally within any extensive region 
there may be limiting factors, such, for example, as continuously high day 
and night temperatures. Otherwise they are likely to be found wherever 
ferns grow and on a surprisingly large number of specific hosts. Natur- 
ally, where those that are . I/; /V.v-in feeling occur beyond the ranges of 
Abies, they can be perpetuated solely by seasonal transmission from affected 
ferns to plants of identical hind or of species that are likewise susceptible. 
Indeed, as the southern distributional limits of Abies are approached, this 
method becomes increasingly frequent, even in those rust species that lack 
amphispores. Of course this melhod is possible for amphispore-producing 
rusts in any latitude, but otherwise only wherever there is a sufficiently 
close overlapping of successive seasonal crops of fronds, that is, a succession 
within the vital life-span of ordinary urediospores. It may not be super- 
fluous to recall to mind here thai the most southerly ranges of existing 
Abies, though well within the tropics in the western hemisphere and 
reaching to the tropics in the eastern, fall far short of the equator.

Not much collecting of fern rusts has been done in the tropics. Yet 
there is a considerable accumulation from mainly incidental collecting 
over the years. These are listed above in Table I, and it is quite an 
impressive compilation, but m\ own limited, yet intensive collectings in 
the tropics of North America, supplemented by occasional contributions 
from correspondents and a lew gleanings from fern collections in the Gray 
Herbarium of Harvard I'niversity. are sufficient to show that the number 
of known fern hosts is probably a small representation of fern species that. 
in one region or another, carry rust fungi. Table II presents new acquisi- 
tions obtained by me in the ways indicated above. Among these are 
unpublished collecting records of a few species listed in Table I; they are 
marked with an asterisk (*). 

One of the reasons for publishing these lists before detailed studies have 
been completed on them is to call I he attention of toilet tors in the tropics 
to a seemingly passed-by group of rust hosts. They will also serve to 
indicate that our knowledge of fern and fir rusts is far from complete. 
Hut now at least enough materials and sources of supply are available to 
justify more adequate taxonomic review and a wider range of other

3. Milesia rusts are correctly recorded for the first time as occurring 
in the Schizaeaceae and Cyatheaceae. To these may possibly be added 
the Gleicheniaceae. 

4. Species of the following fern genera, found growing within the 
tropics, are recorded in this paper as: 

(a) hosts for Desmella rusts: Adiantum (1), Anemia (4), Blechnum 
(1), Cyclopeltis (1), Dennstacdtia ( 1 ), Diplazium (1), Dryopteris (5), 
Pityrogramma (2), "Polypodiacea" (1). Polvpodium (2), Pteris (2); 

(b) hosts for Hyalopsora rusts: Adiantum (2), Anogramma (1), 
Antrophyum (1), Asplenium (1), Athyrium (2), Blechnum (1), Botry- 
chium (1), Cheilanthes (1), Coniogrammr ( 1 ». Cvathea (1), Cystop- 
teris (1), Diplazium (2), Dryopteris (1), Elaphoglossum (2), Pellaea 
(2), Polypodium (4), Woodsia (1); 

(c) hosts for Milisia rusts: Anemia (1). V-plmimn (1), Athyrium 
(1), Blechnum (4), Cheilanthes (2), Coniogramme (1), Cyathea (3), 
Dennstaedtia (6), Diplazium (1), Dryopteris (26), Elaphoglossum (1), 
Gleichenia ? (1), Hemionitis (1). Xephrolepis (3). Onychium (1), 
Odontosoria (1), Pellaea (1), Polybotryum (1), Polypodium (2), 
Poly stic hum (2), Pteris (2), Tcctaria (1); 

(d) hosts for Uredinopsis rusts: Adiantum (1), Anogramma (1), 
Asplenium (1), Athyrium ( 1 ). Blechnum ( 1 ). Cheilanthes (2), Cystop- 
teris (1), Pellaea (1), Polypodium (1), Pteridium (including under P. 
aqudinum its varieties and marginal species). 

The names in black face are genera within the tropics recorded for the 
first time as hosts for rust fungi. The numbers of species reported for 
each genus are indicated in parentheses. 

5. Desmella is reported in this paper on 21 fern host species collected 
within the tropics, Hyalopsora on 24 species, Milesia on 63 species, 
Uredinopsis on 10 species, Puccinia on one species, and Uredo on 4 species. 
The paper lists a total of 109 tropical fern species (exclusive of varieties, 
etc.) known to be hosts of rust fungi; of these 73 are recorded for the 
first time. 

6. I have found 25 rusted fern host species in Guatemala, 27 in 
Jamaica, 27 in tropical Mexico and 9 in Panama. Hashioka, in collections 
made both north and south of the Tropic of Cancer, reported 16 from 
Formosa (as published by Hiratsuka & Hashioka in their "Uredinales 
collected in Formosa"). Varieties are not included in any of these num- 
bers, nor are the submarginal species of I'tendium aquilinum. 

7. According to my experience, rusted ferns in the tropics are rarely 
found below an elevation of about 2000 feet above sea level. Uredo rust 
on Lygodium is exceptional; I collected it at sea level around Puerto 
Barrios in Guatemala. I could find no fern rusts on Barro Colorado 
Island, Panama Canal Zone; the greatest elevation on that island is said 
to be under 550 feet. 

8. Much is to be expected from the vast mountainous regions extend- 
ing eastward from Iran (Persia) to the South China Sea, from which have 



318 JOURNAL OF TilK ARNOLD \KROKhTl M [vol. xxviii 

come scant collections only, and these from very limited northern areas, 
probably in reality extralropical. such as around Kunming. Yunnan, China. 
9. Comprehensive data based on old and new records embodied in fern 
rust collections from the tropics are summarized in Table 111. This table 
designates all the relevant fern genera hosts, the numbers of their affected 
species, the involved rust genera lor each fern genus, and the regions in 
whit h the collections were made.

SPECIES NOVAK FAC ACKAKIM SIMCAKl \1 
Woon-Young Chun and Ying Tsiang 

I'm m ah rial on which this paper is based is part of an extensive 
collection made between the winter of 1942 and the summer of 1945 
under the direction of the junior author. When the situation in Hong- 
kong, where the botanical Institute was temporarily stationed, became 
critical. Professor Tsiang led a part of our staff to northern Kwangtung 
to contact the main body of the University. The attack on Hongkong 
commenced while the party was enroute. In the winter of 1942 a Branch 
Institute was established at Li Yuan Po in southern Hunan, and from this 
new center, botanical explorations in southern Hunan, northern Kwang- 
tung, and the Shih-Wan-Ta Shan region bordering Kwangtung and 
Kwangsi continued throughout the four years of the Pacific War. 

As a result of unrcmittent labor under difficulties needless to detail, 
nearly 10.000 numbers totalling over 100.000 specimens, have been col- 
lected. This large collection is now available to specialists and botanical 
institutions throughout the world. 

Pending the reissue of our Journal Sunyatseniti, this paper is submitted 
to the Journal of the Arnold Arboretum for publication to mark the re- 
sumption of normal relations between our two institutions. 

The types of the new species here-in described arc preserved in the 
herbarium of the Botanical Institute, Sun Y at. sen University; duplicate 
types in the herbarium of the Arnold Arboretum.

This new species may be compared with Lithocarpus ni< ^astachya Hick, 
et A. Camus from which it is amply distinct by isolated, not ternately 
coalescent acorns. The pistillate inflorescence of our new species, as 
deduced from the fruiting state, shows some interesting features. The 
flowers are clustered in 5's in more or less pentagonal groups, but all those 
on the under side of the rhachis remain abortive, and of those more 
advantageously placed in relation to light, only one in each cluster reaches 
maturity. The individual flowers are contiguous but not continent. The 
ripe acorns are alternately juxtaposed in two ranks all facing one direction. 

This outstanding species is named after Dr. \Y. 1\ Fang. Professor of 
Botany in the National University of Szechuan in recognition of his 
exhaustive researches on the flora of Omei Shan, and in appreciation of 
the cooperative spirit dominating his associations with the authors.

This new species is most closely related to Lit Inn arpits dristnairpn 
(Seemen) Rehd. et Wilson from which it differs in thicker coriaceous 
leaves with a fulvous furfuraceous indumentum on the undersurface which 
persists more or less into the second year, and especially in the very 
different fruits. In L. cleistoairpa the acorn is completely adnate to the 
cupule excepting the exposed apex, while in this new species, it adheres to 
the involucre only at the base. 

The wood is hard and durable and is highly valued at least locally for 
making carrying poles. 

It affords us unusual pleasure to associate this handsome and useful 
tree with the name of Professor W. C. Cheng, a dendrologist of outstanding

This new species is distinguished from all other species known to us 
by the thin flat broad involucre, velvet) tomentose inside (excepting the 
basal scar) supporting, but not at all embracing, a slightly narrower more 
or less depressed acorn. The acorns as described are evidently immature, 
those collected later in the season are fully 1.5 cm. long and uniformly 
hemispheric. In most specimens the fruits are solitary but in others they 
are borne, back to back, in pairs from the same level on opposite sides of 
a short spike.

This evergreen oak with unusually small acorns is very common in the 
vicinity of Li-Yuan Pao, I-chang Hsicn, S. Hunan where a branch of the 
Botanical Institute was established throughout the war. It thrives from 
levebland up to an altitude of 1000 m., intermixed with deciduous species 
and conifers. Its range extends from the northern part of Yu-Yuan 
District in Kwangtung province to the foot of Mang Shan, the famous 
region in southern Hunan where virgin forests still exist. The edible acorns 
of this tree, colloquially called t'hui-li, are sold in local markets. The 
wood is fine and durable, much used by the natives for making furniture 
and handles of various kinds of tools. It is especially good for preparing 
charcoal. 

This graceful oak which no doubt will become a common ornament in 
local and foreign gardens is named after the collector, Mr. Pao-Han 
Liang, Lecturer in Botany of this Institute.

Differs from Q. Ihissaiuiii Hick, et A. Camus in the dentate leaves with 
more numerous lateral veins and the shallow cup only supporting, not 
at all enclosing the acorn. According to the collector, this oak is suitable 
for carpentry. The felled logs left in situ are used for the culture of 
edible mushrooms. This tree has ornamental qualities which recommend 
it for landscape planting.

Although the two specimens are not exactly comparable, the one collected 
by A. Henry on which Sprague's species is based is in flower, and the 
other, described by Hayata. is in fruit, we are confident that two distinct 
species are involved judging by vegetative characters alone. Rccvcsia 
jormosana Sprague is easily distinguished by the rounded to cordatulate 
leaf-bases.

While working over the Rubiaceae of Papuasia as represented in the 
Richard Archbold Expeditions collections from New Guinea, and the 
Brass and Kajewski collections from the Solomon Islands, we found the 
above cited specimens which we were unable to name to genus, although 
they clearly belong in the family. For this material we here propose the 
new genus Kajewskidla. At present we are unable to suggest an affinity 
for it. According to the classification of the family in Kngler and Prantl, 
Pfianzenfam. IV. 4: 16. 1891, it seems to belong to the Oldenlandieae. In 
its ferrugineous-villous indumentum, in its stipules, in the form and texture 
of the leaves as well as in the venation, and in the minute reticulate- 
punctate seeds, Kajiicsk'nlla strongly suggests. X aiitknphytum Reinw., but 
in its technical characters it is not allied to that genus. The very slender 
terete capsule is somewhat like an abbreviated fruit of Dolicholobium A. 
Gray; both have septicidal dehiscence, and the exocarp becomes more or 
less shredded in age as in that genus, and in Hikkia Reinw.; the valves of 
the fruit persist as in the latter genus, and the placentae are either broken 
free or attached along the margins of the valves. The similarity of these 
characters, however, is probably only superficial. The fairly large tubular 
or very narrowly elongate obconical corolla entirely glabrous within, the 
glabrous stamens attached a little above the base of the corolla (about 
where it emerges from the calyx), the non-papillate stigma, and the short 
slender terete capsule seem to offer a combination of characters which we 
believe worthy of generic recognition.

l.ieania oli^antha is characterized by its very compact few-flowered in- 
florescences and its concolorous essentially glabrous leaf-blades. From 
/.. leueosepala Griseb., originally described from Guadeloupe but also 
recorded from Dominica. Si. Vincent, and St. Lucia (by R. 0. Williams. 
Fl. Trinidad & Tobago I: 315. 1932, as Moquilca leueosepala) , the n?w 
species differs not only in its inflorescence, but also in its slightly smaller 
leaf-blades with fewer secondaries and its obscurely sericeous rather than 
cano-tomentose calyx. In referring plants of this alliance to Lie an hi 
rather than Moquilca, I follow the generally accepted reduction of the 
latter genus. 

Concerning this species Dr. Beard writes: "It is a small tree with a 
trunk up to 30 cm. in diameter; the wood is hard and of no economic 
value. It is almost confined to the exposure sub-type of the rain-forest 
in the interior of St. Lucia, occurring on the crests of all but the highest 
ridges and I'itons. I have noted it on La Sorciere, I'iton Flore, Piton St. 
Esprit, Grand Magazin, Morne Tabac. and the slopes of Morne Gimie, at 
elevations of 1600 to 2200 ft. [Note: The type-collection was found at 
a lower elevation]. 'The species is not found in the elfin woodland at 
the top of Morne Gimie (3000 ft.), and it is very rare in the normal 
rain-forest of lower elevations. In its particular association it is one of 
the principal dominants, forming approximately 30% of the stand. The 
associate dominants arc 1/: /■<.'/>//,.■/.'.■, < In ■■!>/': ; nirftw, Myrcia sp. [Beard 
no. 7/\V), and Tovomita I'lumieri. Together with a number of species of 
lesser abundance, these plants form a low forest of small trees some 30 ft. 
high, a reduced type due to exposure to wind. In the other islands the 
principal dominants of the equivalent forest type are Rieheria grandis, 
Micropholis chrysophylloid.es, and Podocarpus eoriaeeus. The first of 
these has not been found by me on St. Lucia, and the last is very rare, 
found only on Morne Tabac. The Lieauia olii^antha-Mieropholis 
chrysop/iv/loidc.s association of St. Lucia is, therefore, an interesting 
special type."

ASTRAGALUS IN ARGENTINA, BOLIVIA AM) CHILI. 

Ivan M. Johnston 

Only in Soith Amkrica does the great genus Astragalus have an 
extensive development in the southern hemisphere. There are ten species 
reported from the mountains and plateaus of tropical Africa. In the 
temperate southern parts of that continent the genus is represented only 
by one species in Natal. In South America, however, there are nearly 
ninety species. The genus is represented along the Cordilleras from 
F.cuador to the Straits of Magellan, and has two important centers of 
speciation, one in the high count r\ of northwestern Argentina and adjacent 
Bolivia and another in adjoining Chile and Argentina along the Cordilleras 
south of the peak of Aconcagua. 

Though the present paper treats the species known from south of Peru, 
all the South American species of Astragalus were studied during its 
preparation. Accounts of the two Ecuadorean species, and of seven of 
the Peruvian species have already been published. Jour. Arnold Arb. 
19: 88-96 (19.CS). The present paper treats the remaining seventy-seven 
species of the genus known to me from South America. 

In general structure and appearance the South American Astragali are 
rather similar to those found in North America. Their relations are with 
the North American and not with the Old World members of the genus. 
They are probably the products of an ancient southern migration and 
subsequent differentiation of various types originating in North America 
where the genus has one of its major evolutionary centers. In North 
America, Astragalus is represented from Alaska and Baffinland south to 
northern Guatemala, with most of its more than three hundred species 
concentrated in western United States. The areas occupied by North and 
South American species are, accordingly, separated by Colombia and nearly 
all of Central America, and their major areas of speciation by the great 
distance between Argentina and the Cnited States. 

The close relationship between North American species and others in 
Argentina and Chile is frequently very clear. Indeed, some of the 
southern plants seem to be more closely related to the northern ones than 
they are to any found on their own continent. None, however, seems to 
be specifically identical with North American plants. Though there are 
many close similarities between northern and southern species, evolution 
in South America has not closely paralleled that in North America. This 
becomes very clear if an attempt is made to apply to the South American 
species the system of segregate genera set up for the North American 
species by Rydberg, No. Am. IT 24: 251 462 (1929), and Am. Jour. Hot. 
15:584-595 (1928), 16:197-206 (1929), and 17:231-238 (1930). 
Some of the South American species fall readilv into the Rvdbergian 



19471 JOHNSTON, ASTRAGALI S 337 

segregates, but many straddle the arbitrary lines between these so-called 
genera, and others simply do not hi into any of them. 

No satisfactory subgeneric classification of (he South American species 
has been worked out. Rydberg's classification seems artificial at many 
places and furthermore is to be condemned as provincial, since it is based 
almost exclusively on species of one region and without full consideration 
of those in other parts of the world. It would have to he modified con- 
siderably, as well as amplified by the addition of comparable new groups, 
before it could accommodate the South American species satisfactorily. 
That, however, is a task that should be left to a monographer with a wide 
acquaintance of the genus as developed in all [tarts of the world. 
Astragalus has only one clean line of cleavage in South America. This 
breaks the genus into two natural groups probably worthy of generic- 
recognition. One, the section Phaca, with fifteen species, is readily 
distinguished by its well separated, distinct, herbaceous stipules. The 
other, the section Euastragalus, has more or less united, membranous, 
ochraceous stipules and includes over seventy species. 

In the present paper the synonymy given for the species is complete 
except for certain names published by Otto Kuntze, Rev. Gen. 2: 940-949 
(1891), and 3 2 : 73 (1898). Substituting the name Tragacantha for 
Astragalus, Kuntze published hundreds of new combinations under the 
former invalid name. It has seemed a waste of space to reprint the scores 
and scores of useless binomials he applied to South American species. 
Only when he coined new specific epithets for South American species, are 
Kuntze's names of any taxonomic significance and only the latter are listed 
in the synonymy given in this paper. 

Among the large number of specimens studied, only about half are cited. 
Under well understood species, of which I have seen numerous specimens. 
I have cited only selected collections to show geographic range. Only 
under new, rare, or poorly understood species has all the examined material 
been cited. The particular herbaria in which the examined specimens are 
located are indicated by abbreviations, in parentheses, following the 
collector's name. 

During the preparation of this paper the specimens in many herbaria 
have been examined. The basic herbarium and library work was carried 
on at the Gray Herbarium. During a visit to Europe the genus was 
studied at Kew, London. Hamburg. Berlin. Munich. Geneva, and Paris, 
and loans of selected material from these botanical centers were later 
studied at the Gray Herbarium in conjunction with loans of South 
American Astragali from Stockholm. I'psala, New York. Washington, and 
Chicago. From South America much interesting material has been 
received on loan and for identification. Dr. Angel Cabrera of La 
Plata, sent specimens and arranged the loan of Spegazzini's Astragalus. 
To Prof. L. R. Parodi, Dr. Arturo Burkart. Prof. Alberto Castellanos, Sr. 
A. Ruiz Leal, and Sr. Juan Y. Monticelli I am indebted for many interest- 
ing specimens. Prof. Marcial R. Espinosa sent me some of the collections 



338 JOURNAL OF THK \KNOLD VRBOKKTl M Ivor., xxvm 

and very obligingly loaned me fragments of certain critical specimens in 
the Philippi Herbarium. Other very interesting and useful Chilean collec- 
tions have been received from Sr. Gualterio Looser, Sr. Ciilberto Montero. 
and Dr. C. Grandjot. I have had help from many sources and I am 
grateful to the many botanical friends in Kurope and America who have 
aided in this work on the genus Astragalus.

This slender erecl growing fruticose species varies I'nun glahrescent to 
very densely strigose. The plants with the densest indument come from 
the province of Coneepeion and are the typical form of .1. Chamissonis. 
Philippics A. nioiiosprrnuts appears to he this densely strigose form. 
Plants from beyond the province of Coneepeion are much more sparingly 
strigose and some of these Income glabrescent in age. I do not believe 



1947 1 JOHNSTON, ASTRAGALUS 347 

that practicable segregates of this species can be found upon degree of 
pubescence. The older writers often used greek letters to distinguish this 
variation. Phaca ochroleuca var. fS of Hooker & Arnott, I.e., is based upon 
Cuming s!( > lrnm Concepcion. It is typical .1. Chamissonis. At Paris 
Clos has labeled Gay 586 h. Ch., from "Chile," as the var. j3 and has 
appended a note which probably indicates the source of his var. 8. "Les 
deux echantillons de Phaca ochroleuca H. et Arn. dans Uherbier Webb sont 
differents en ce qu'un est glabre et l'autre est tomenteus." The var. £ 
of .1. platens, Clos. I.e. 109, is based upon Bert era 824 from Valparaiso. 

The inadequately described /'. ehilensis Nees. appears to belong to the 
present species. At Munich there is a good specimen of our present plant 
associated with a label reading "Phaca ehilensis — hort Monoc. — 1838/' 
A similar specimen at Berlin has a label, in three different scripts, which 
may be indicated as follows. "714 — Dalea? e Chile — var. dubia OK 
— HORT. BOT. BEROL. — 31."

One of the collection upon which Philippi originally based this very 
distinct species is labeled as having come from Chanaral. in northwestern 
Coquimbo. Subsequently, however, the species has been found only in the 
region about Chacabuea Pass, to the north of Santiago. I suspect that the 
specimen said to have come from Coquimbo may have been mislabeled. 

The coarse flower, the elongate pedicels, and the large papery long- 
stiped pendulous pods are outstanding characteristics of this species. It is 
very distinct but probably has its closest relative in C. limariensis from 
which it differs in its coarser flowers, more papery pendulous pods and 
broader flat closely strigose leaflets.

I have seen specimens of this readih recognizable species from Ouintero. 
Concon, Renaea, Valparaiso and Gonstitucibn. Of the synonyms listed I 
have seen authentic material of all hut P. amtidois. All clearly belong 
to the unmistakable species treated here. 

Though originally given as from the Galapagos Islands, the collection 
by Kdmonstone which is I he type of /'. lidmonstoiui is unquestionably t re- 
present Chilean plant. Kdmonstone was the botanist on the cruise of the 
Herald during which visits were made in Chile (Valparaiso and Concep- 
cion) and Peru as well as on the Galapagos Island. His collections became 
confused after his untimely death in Kcuador in 1S46. It may be noted 
that the other Galapagean records for Astragalus are also based upon 
falsely labeled specimens. The collection by I hi Petit-Thouars, mentioned 
by Hooker when he described /'. P'.dmonstonei. represents flowering ma- 
terial of .1. Mnizicsii Cray, probably from Monterey, California. Astra- 
galus hrrvidrntatus Wright. Kew Bull. 200 (1006), also attributed to the 
Galapagos, is certainly this California!! plant. Cf. Johnston Jour. Arnold 
Arb. 19: 95-96 (1938).

A well marked species probably most closely related to .1. verticillatus 
of south central Chile. It agrees with its relative in gross habit, flower 
shape and size, inflorescence, and narrow elongate leaflets, but differs in its 
much larger, differently shaped and distinctly stiped pod.

Espinosa (G). Concepcion: Penco near Concepcion, Oct. 1890. Xeger (Munich); 
Araucania, Nov. 1887, Philippi as P. verticillata (isotype, G, BM.) 

The type of /'. verticillata is given as collected in Nov. 1887, in 
"Araucania." It is very similar to the material from Penco collected by 
Neger. Both specimens have flower but lack fruit. The leaflets are 
geminate and very slender. During his "Botanische Excursion in das 
Araukanerland" in Nov. 1887, cf. Bericht. Ver. Xaturk. Kassel vol. 41 
(1896), Philippi visited San Javier, Concepcion. Angol, Traiguen and 
Temuco. Accordingly his type collection of 1. verticillatus could have 
originated in the vicinity of Concepcion where Neger collected specimens 
very much resembling it. 

The material I have seen from the watershed of the Rio Maule is coarser 
and has less slender leaflets than represented in the type of .1. verticillatus 
and in Neger's plant from near Concepcion. This more northern material 
is that described as P. brachytropis upon the basis of a plant from San 
Javier, prov. Maule. Its leaflets are usually in pairs along both sides of 
the leaf-rhachis but in one collection from Talca, agreeing in all other 
details with the species, they are solitary along the rhachis. 

The species is evidently related to .1. Pissisi with which it agrees in such 
distinctive details as color, size, and structure of the corolla and unusually 
elongate pedicels. It differs from its relative in having much smaller 
(5-10 mm. long), globose or ovoid pods, that are sessile in the calyx (not 
stiped) and borne on erect pedicels. The pods bear scattered appressed 
usually pale hairs. They are usually abruptly contracted at the base. 
Philippi describes P. verticillata as having corollas in which the wings are 
short and only half the length of the keel. This is evidently a mistake. 
Authentic material of the species shows the corollas to be like those of 
/'. brachytropis which he properly described as having wings almost twice 
as long as the keel. Reiche so described them in his Flora de Chile.

A species evidently related to ,1. Berterianns and one resembling that 
species in habit of growth, and size, shape and structure of fruit. The new 
species is a plant of the Cordilleras. Its relative belongs to the valleys and 
coastal hills and is quicklx distinguished from the montane plant by a less 
robust habit, conspicuously hairy herbage, and smaller, less juicy leaflets. 
Astragalus Looser/! is best known from the mountains east of Santiago. 
Philippi and Reiche seem to have confused it with the very different 
.1. curvicaulis. 1 have been unable to separate the plants of the Cordilleras 
above Santiago from some that come from the Cordilleras further north in 
Coquimbo. The four sheets at Paris collected by Cay and determined by 
Clos as /'. data contain varying mixtures of three species. The pre- 
dominating plant, however, is the northern form of A. Looserii.

The type of .1. Berterianus was grown in Italy from seeds sent by Bertero 
from Chile. Since Bertero seems to have made only two collections of this 
species, one near the Rio Maipo in May. 1S2X and another near Rancagua 
along the Rio Cachapoal in Oct. 1828, one of these, probably the former, 
is the source of the seed he sent to Turin. The latter collection supplied 
the type of A. oblongifolius Clos.

locality is given for Cay S7f> at Paris, but at Geneva it is labeled as from 
the province of Coquimbo. Since Gay does not appear to have collected 
in the upper Aconcagua valley, which seems to be the southern limit of 
the species, it seems probable that he must have obtained his material in 
the eordillera east of Ovalle or Coquimbo. The type of P. data is simply 
given as from the Cordilleras of Chile. Cuming, its collector, is known to 
have collected in the upper Aconcagua valley where the species is best

known, and it is practically certain that his material must have come from 

that area. The var. fS mentioned by Hooker & Arnott, I.e., based upon 

Cuming 734 represents A. Berterianus. The present species is a very 

distinct one, unique in its firm strict elongate lancoid pods. It has been 

confused with A. Looserii but is readily distinguished from that species by 

its much larger more inflated and rounded fruit, smaller flowers, scanty 

short pale, rather than dense conspicuous black indument on the ovary, 

fruit and calyx, and cinereous rather than green juvenile leaves.

This appears to be the most common Astragalus with inflated pods found 
in the Cordilleras of Ataeama and Coquimbo. It may be related to .1. 
coqu'nnbcnsis. which occurs at low altitudes west of the Cordilleras, but 
differs from that annual in its strong perennial root and somewhat smaller 
capitately congested pods. When I examined the type of .1. Echegarayi 
I identified it with A. vagus, but subsequently as my studies of the genus 
progressed I have come to wonder if it might not really be a form of 
A. monticola. Phaca San Romani, however, is unquestionably a synonym 
of the present species.

The type of A. Darumbium is a very rank plant with coarse decumbent 
stems becoming 1 m. long and 7 mm. thick. It was discovered along a 
stream at the base of the Cordilleras and thought to be a possible waif 
washed down from higher altitudes in the mountains ( fortasse semina ex 
cordilliera provenant"). Similar very coarse plants have not been re- 
discovered. A very closely related plant, however, has been found in the 
Cordilleras and described as /'. nun rophysa , P. robusta and A. atuelii. 
This latter has shorter more slender stems, smaller leaves, perhaps shorter 
pedicels and larger black-hairy pods. The most reduced form is P. 
macrophysa. Apparently intermediate between this and the type of A. 
Darumbium is P. robusta. The indument on all these forms varies from 
sparsely to very densely strigose, some plants appearing glabrous at first 
sight while others are obviously silky with abundant appressed hairs. 

When A. atuelii was originally described the type was given as from 
900 m. altitude and as representing Wilczek's collection no. 3 72. The 
label on the type at Geneva, however, gives the altitude as 1900 m. and 
the collection number as 86. 

The species is related to .1. monticola and, in fact, grows with it in the 
Cordilleras east of Santiago. It is distinguished from this relative by its 
usually larger fruit, slightly more elongate calyx, and silky appressed 
indument. Some of the montane forms have a root that is much more 
slender than in other cordilleran species of this general relationship, and in 
gross habit frequently suggest forms of 1. t oquimbensis and A. paposanus. 
The two latter species, however, are not closely related to our plant and 
are readily distinguished by having pink rather than violet or purple 
corollas.

A species evidently related to the montane form of A. Darumbium and 
differing from it chiefly in having dull spreading, rather than silky closely 
appressed hairs on the leaves, stems and fruit. Though .1. monticola and 
.1. Darumbium sometimes grow together (Dr. (irandjot collected them both 
at Valle de Hierba Loca and at Cerro I'rovencia) they maintain their 
characters and are readily separable. The type of .1. Barcrloi, as Philippi 
suspected, is almost certainly mislabeled. The label on the type at 
Santiago reads "Astragalus Barcrloi. Cord, de Chilian?," but the specimen 
agrees closely with the material 1 have cited from the Cordilleras east of 
Santiago and I believe probably originated there.
