PREFACE

MONG the plant families that constitute the vegetation
A of the Philippine Islands the Orchidacez is the richest
in representatives. It exceeds the Rubiacew, the next largest
family, by several hundred species. Although, in addition to the
regular explorations carried on by the botanical department of
the Bureau of Science at Manila, several collectors have given
special attention to the search for orchids, there are still large
areas, botanically unknown, from which it is highly probable
that rich accessions to our orchid herbaria will be made.

In the list that follows it has been necessary to exclude many
species referred by authors to the Philippines on questionable
evidence or on unreliable data. At the same time several spe-
cies have been included which, though inadequately known be-
cause of the absence of types, were originally described from
material supposedly of Philippine origin. Furthermore, for pur-
poses of discussion, a very few species have been admitted to
the list which have not yet been found in the islands, although
ascribed to them by monographers.

The genera Arundina and Bromheadia have been reported
from the Philippines on the evidence of Cuming’s 2058 and 2054.
Vidal, in a footnote on page 88 of Phanerogame Cumingiane
Philippinarum, excluded 2053 to 2058 inclusive from the Phil-
ippines, and states that they belong to specimens gathered at
Singapore. Naves ascribes Arundina pentandra Reichb. f. and
A, Wallichii Reichb. f. to Luzon, but on evidence which we may
safely disregard.

Dendrobium lamellatum Lindl. is given an extension of range
by Fritz Krinzlin in his recent monograph, that includes the
Philippines. The basis of this extension is Cuming’s 2074. Unfor-

[ ix ]

PREFACE

tunately I have not seen the material collected by Cuming and
distributed under this number, but I suspect that it may prove
conspecific with D. platycaulon Rolfe, which is a near ally of
D. lamellatum. I have not seen any specimens of D. lamellatum
among the collections from the Philippines that I have examined,
although several specimens referable to the endemic D. platy-
caulon have been received from the Bureau of Science.

In the early days of Philippine botany new acquisitions were
described in numerous journals, for the most part in brief terms,
consequently it is a difficult task to make a comprehensive enu-
meration of the different kinds, to clear away the obscurity that
surrounds some of them, or to identify, in the absence of type
specimens, those that were published as new by the pioneer
students of the Philippine flora. Taken as a whole, however,
the doubtful species are comparatively few if those that authors
have ascribed to the Philippines conjecturally are removed
from consideration. That this should be so is all the more surpris-
ing when it is realized that the types on which Blanco’s first and
second editions of the Flora de Filipinas were based have not
been preserved.

When the third edition of Blanco’s Flora was made ready for
publication at Manila under the auspices of the Order of Au-
gustinians, Andreas Naves, who wrote the part of the Novis-
sima Appendix devoted to the orchids and other monocotyle-
donous groups, included a number of names on the authority
of a list transmitted to him by Sebastian Vidal, the author of
Phanerogame Cumingiane Philippinarum. This list is cited
by Naves as the Boxall Manuscript. It was prepared by Boxall,
not from collections he personally had made in the Philippines,
but from horticultural and other sources consulted prior to his
departure from England. In other words, the Boxall Manuscript

[x]

PREFACE

was just such a guide as a horticultural explorer might take
to a new country. It was not a list of actual discoveries made
by its author, nor a record of plants of indisputable Philippine
origin, but a compilation that was to prove useful for refer-
ence. In my enumeration of genera and species in the follow-
ing pages I have regarded Boxall’s manuscript as useless for pur-
poses of citation unless subsequent collections have verified its
contents.

The unrestrained adoption of Boxall’s manuscript list does not
complete the shortcomings of the Novissima Appendix, because
the determination of its authors to reduce Blanco’s species to
older ones, on the assumption that few of them were new, and
their efforts to identify with the plants of India and the Malayan
region the components of the Philippine flora resulted in numer-
ous errors in judgment. A single example will suffice to make
clear what I mean. Cypripedium Fatrrieanum was included by
Naves as a native of the Philippines, although its habitat at the
time was extremely doubtful. The native country was not defi-
nitely known until 1905, twenty-two years after the publica-
tion of Naves’ work, when specimens were found in the valley
of the Torsa or Amuchu River (Machoo of some authors), in the
Chumbi district of Western Bhotan, in India.

It has been estimated that of the one thousand one hundred
and twenty-seven species and varieties of plants described by
Blanco five only were deemed valid by the authors of the Novis-
sima Appendix. In other words, one thousand one hundred and
twenty-two of them were reduced to synonymy without discus-
sion. Merrill sums up the revision of Naves and his colleague,
Fernandez- Villar, as follows: “It is evident that these authors
accomplished their work in the library rather than in the field
and in the herbarium, and that they reduced Blanco’s species to

[ xi ]

PREFACE

those of other authors not so much by a study of botanical ma-
terial as by an examination and comparison of descriptions.”

The orchid flora of the Philippine Archipelago is closely al-
lied to that of Celebes, Java, and the Malay Peninsula. There
are no endemic genera. The number of endemic species, on the
contrary, is very large, at least six-sevenths of the known ones
having been found nowhere else. It is safe to say that approxi-
mately ninety per cent of the orchid flora is endemic.

In the following enumeration seven hundred and twenty-three
species distributed among one hundred and one genera are
admitted. Of this number one hundred and nineteen species
and one variety are herein proposed as new. The species of the
Apostasiine have been dropped, as this group should, in my
opinion, be excluded from the Orchidacee. The sequence of the
genera conforms closely to that adopted by Pfitzer in Engler
and Prantl’s Die natiirlichen Pflanzenfamilien, but several points
of dissimilarity that distinguish my arrangement from Pfitzer’s
should be noted, as they seem to establish a more natural group-
ing. In my treatment of the Sarcanthine I have attempted to
bring the genera into accord with modern botanical thought, and
to recognize those deviations from Pfitzer’s interpretation of
affinities that recent studies have proved to be desirable. The
genera of the Sarcanthine, however, are by no means, even
now, thoroughly understood, although late investigations have
done much to bring us nearer to a rational solution of those prob-
lems that have perplexed botanists for many years, have given
rise to discussion, and have produced a copious synonymy.

In my remarks about several of the species enumerated in the
following pages I have had occasion to refer to the plants col-
lected by Camelli. Georg Joseph Camelli (Camell or Kamel), in

[ xi |

PREFACE

whose honor Linnzus named the genus Camellia, was a mission-
ary who passed a number of years in the Philippines, where he
devoted part of his leisure to the collection and study of botan-
ical specimens. In 1704, in an appendix to the third volume of
Ray’s Historia Plantarum, descriptions of Camelli’s plants were
published. This appendix is of importance, as it constitutes one
of the earliest records of Philippine botany. Camelli prepared
drawings to illustrate his specimens, but no attempt was made
to reproduce them until Jacob Petiver published a plate of the
orchids in his Gazophylacium. Petiver’s plate represents modi-
fications of the originals, much reduced, that make possible ap-
proximate identifications. The original drawings are still extant,
and are preserved in the Sloane collections at the British Mu-
seum.*

In the citations of collectors’ numbers the abbreviations Bur.
Sci. and For. Bur. refer to the Bureau of Science and the For-
estry Bureau at Manila. C.A.Wenzel’s field numbers, cited in
the references to distribution, are preceded by a cipher, to dis-
tinguish his orchids collected especially for me from the speci-
mens of his general collections distributed to the subscribers to
his sets of plants from Leyte. As Wenzel unfortunately num-
bered both his orchids and general collections alike, confu-
sion would be inevitable were not some means of distinction
adopted.

A complete bibliography has not been included in this work,
as most of the species have been amply treated in the preced-
ing volumes of OrcHIDACE# or in my contributions published
in the Philippine Journal of Science. Furthermore, with very few

* Photographic copies of the orchid drawings, for which I am indebted to Dr. A. B. Rendle,
are in my herbarium.

PREFACE

exceptions, a detailed account of geographical distribution has
been confined to the new species.

As it is yet too early to offer an orchid flora of the Philip-
pines, the following pages should be regarded simply as a con-

tribution toward such a flora.

GENERA AND SPECIES OF
PHILIPPINE ORCHIDS

I. DIANDRA-CYPRIPEDILINA

OUR genera are recognized. Cypripedium Z. has representa-

tives in both hemispheres. Selenipedium feichb. f. is a small
genus of tropical American species. Phragmopedium Folfe, a
genus of horticultural value, is chiefly South American. Paphio-
pedilum Pfitzer is confined to the tropical regions of Asia and
the East Indies. Five species, all of which are cultivated for the
beauty of their flowers, are natives of the Philippines.

1. PAPHIOPEDILUM Piitz.

In the Orchid Review of January, 1912, R. A. Rolfe discussed the
nomenclature of the Cypripediline, and in a footnote referred all
the species which are representatives of Paphiopedilum to Cor-
dula Rafinesque.

Rafinesque, in Flora Telluriana, part 4 (1836), page 46, pro-
posed four new genera, Sacodon, Stimegas, Cordula, and Nemo-
phora, to include species of Cypripedium. The first of these is rep-
resented by the group of which Cypripedium macranthum Sw. is
an example. Stimegas and Cordula, as understood by Rafinesque,
include species which Pfitzer referred to Paphiopedilum. Under
Stimegas Rafinesque included Paphiopedilum venustum and under
Cordula P. insigne. The fourth genus, Nemophora, from the de-
scription of the type species, is congeneric with Paphiopedilum.

These Rafinesquean genera were not unknown to Pfitzer when
his Orchidacez-Pleonandre for Engler’s Das Pflanzenreich was
prepared, but with the exception of Sacodon, Pfitzer wrongly
referred them all to the synonymy of Paphiopedilum. On the

[9 ]

basis of priority Mr. Rolfe is justified in taking up Cordula, but
surely we may hope that Paphiopedilum will be added to the
list of genera which one must retain regardless of priority. Cor-
dula, if adopted, will be most inharmonious in a group which
has been distinguished by uniformity in the termination of its
generic names.

Two of Pfitzer’s subgenera of Paphiopedilum are represented
in the Philippines.

ORCHIDACEAE

Patawan, Bouor, Cuming 2060. As Cuming also collected in Malacca,
and as P. barbatum is a native of Mount Ophir, his 2060 may have come
from there.

5. Paphiopedilum ciliolare (eichb. f-) Stein Orchideenb. 462.

Minpanao, Dinacat.

Two other species of Anatopedilum have been reported from
the Philippines, but on evidence that is not quite satisfactory.
P. Lowi (Lindl.) Stein is a Bornean species which, it is believed,
has been discovered in the Sulu Archipelago. (Cf. Orchid Review
3:129,193.) P. Rothschildianum (Reichb.f.) Stein is another Bor-
nean species which has been given an extension of range that
includes the Philippine Islands.

In 1899 I obtained at the nurseries of Messrs. Hugh Low &
Co., England, a specimen of a supposed natural hybrid which
had been imported from Palawan. At least the records at hand
indicated that the plant had come from a collector who had
passed part of his time on that island. This hybrid proved to be
the same as P. x Kimballianum, a natural hybrid produced by
a cross between P. Rothschildianum and P. Dayanum, both na-
tives of Borneo. P. x Kimballianum may be a native of Palawan,
but, aside from the garden name Cypripedium x palawanense,
there is no evidence at hand to prove that it is. P. x AKimballa-
num was originally imported from Borneo.

Although for many years I have had under observation almost
every known species of Paphiopedilum, including many varieties
and several hundred hybrids, I find it very difficult to identify
with surety dried specimens. I have at least two species from the
Philippines that I have been unable to identify. These are repre-
sentatives of the subgenus Otopedilum.

One species is known to be a native of the Philippines. About
twenty species have been described.

3. HABENARIA Willd.
Platanthera and Peristylus are here included. In the third vol-
ume of OrcHIDACE I gave my reasons for keeping Habenaria
intact. In Die Orchidaceen von Deutsch-Neu-Guinea, Dr. R.
Schlechter refers Peristylus to Habenaria as a section and keeps
Platanthera as a distinct genus.

help to distinguish H. Amesiana from H. angustata, there is a
conspicuous difference in the size of the flowers. Specimens from
the Philippines and specimens from Java, the latter determined
by J. J. Smith, are before me, which show a difference of 7 mm.
in the length of the spur; that of H. angustata measuring 14mm.,
that of H. Amesiana 7 mm.

from Cuming’s 2091. From this same number Reichenbach f.
described HZ. aristulifera. Kranzlin describes the petals as bipar-
tite. The only species with bipartite petals from the Philippines
are H. Leibergu, H. aristulifera, H. Curranii, and H. lingu-
losa. H. Cumingu, from the description, is unlike any of these.
H. dichopetala Thw. and H. lancifolia A. Rich. are cited as near
allies.

No habitat other than the Philippines is given by Krinzlin in the ori-
ginal diagnosis.

The type consists of a single specimen. In habit it suggests a
depauperate H. aristulifera, and in fact has aristulate tips to the
leaves. The lateral sepals are dependent; near the apex, on the
dorsal side, the thickened mid-nerve protrudes to form a subulate
tip (as in HZ. repens). The underground part of the plant in the
type specimen is apparently incomplete. From the parts remain-
ing it would seem to have had two cylindrical, fleshy, tuberoid
roots 2 cm. beneath the surface of the ground. The flowers of the
type are in a poor state of preservation, consequently it is im-
possible to describe the details of the gynostemium.

4. DISPERIS Sw.
Only one species of Disperis has been reported from the Philip-
pines. Schlechter ascribes fifty species to the genus, of which more
than forty are natives of Africa. D. rhodoneura Schltr. comes from
New Guinea, and D. philippinensis Schltr. from the Province
of Papanga, Luzon. The type of the latter was collected in Sep-
tember, 1905, at an altitude between three hundred and seven
hundred meters, by Elmer D. Merrill (4215). It is a small ter-
restrial species, hardly 8 cm. tall, with sessile, ovate, acute leaves
+1 cm. long. The flowers are purplish and odorless. In habit it
resembles D. Bolusiana Schltr. and D. villosa Lindl.

flowers are said to be similar to those of D. zeylanica Trim.

5. THELYMITRA Forst.

The genus Thelymitra is essentially Australian. More than half
of the forty-four species now known come from that country.
About twelve are natives of New Zealand. Only one species is
known to be a native of the Philippines. T'helymitra malintana
Blanco FI. Fil. ed. 1, 642 is unknown to me. Naves referred it to
Habenaria trinervis Wight, a species that has never been au-
thentically reported from the Philippines.

ent understood, is a native of southern China, Japan, Formosa,
Liukiu Islands, Java, New Caledonia, Australia, and New Zea-
land. Undoubtedly studies of specimens from the wide range
indicated will result in the recognition of several species that are
now confused with M. wnifola.

7. CORYBAS Salisb.

There appears to be no valid reason for upholding the generic
name Corysanthes Ff. Br. It is antedated by Corybas, and, in ac-
cordance with the rules of nomenclature adopted by the Vienna
Botanical Congress, is not available. The description of Corybas
aconitiflorus in Salisbury’s Paradisus Londinensis is accompanied
by a plate that leaves no room for doubt as to the generic char-

[ 18 ]

ORCHIDACE

acters of Corybas. In his Prodromus Flore Nove Hollandize
Robert Brown gave his reasons for excluding this genus, reasons
which it is difficult to consider seriously to-day.

The genus includes about thirty-eight species, sixteen of which
are natives of New Guinea. Nine or ten species have been re-
ported from New Zealand, and about four from Australia. Cory-
bas Merrilla marks the northern limit of distribution for the
genus.

8. CRYPTOSTYLIS R&. Br.
There are about fourteen species of Cryptostylis reported to be

Borneo, Ceylon, Malay Peninsula, and the Fiji Islands.

9. GALEOLA Lour.
About fourteen species have been described. C. A. Wenzel, who
has collected Galeola pterosperma in Leyte, reports that a super-
stition prevails among the natives that if this plant grow near
a human habitation, the occupants will die.

10. VANILLA Sw.
More than fifty species of Vanilla have been described. These are

[ 19 ]

ORCHIDACEA

conveniently divided into two large sections, one characterized
by leafy, the other by leafless stems. Both sections are represented
in the Philippines, each by a single species.

Vanilla is of special interest, as it contains the only orchids
that are economically important.

Vanilla majaijensis Blanco is a doubtful species which authors
have referred to VY’. planifola Andrews, the vanilla of commerce.
if this treatment is correct, then Blanco’s specimens, as Mr.
R. A. Rolfe suggested in his monograph of the genus Vanilla,
may have been introduced from Mexico by the Spaniards.

V.ovalis Blanco, which Naves considered identical with V. aro-
matica, is probably conspecific with V. majazjensis. In my herba-
rium there is a specimen from Laguna Province, Luzon, the
type locality of V. ovalis, which Mr. Merrill has referred to V.
ovalis Blanco. If Mr. Merrill’s suppositions, published in his re-
view of the identifications of the species described in Blanco’s
Flora de Filipinas, are correct, V. ovalis and V. majaijensis are
conspecific, in which case V. ovalis Blanco would by priority be-
come the name of the species. Unfortunately Blanco’s types
are no longer in existence, so that no clear understanding of his
species can be reached.

The next step is to examine V’. philippinensis Rolfe. The spe-
cimen from Laguna Province, referred to above, which Merrill
identified as V. ovalis, appears to be conspecific with V’. philippi-
nensis, and is a native of the region from which Blanco’s mate-
rial was received. It is impossible to arrive at a definite conclu-
sion, but conjecture surely favors the supposition that V. ovalis,
V. majaijensis, and V. philippinensis are one and the same; a
conjecture strengthened by the evidence which has gradually
accumulated to show that V. philippinensis is not uncommon in
the Philippines, while no other species comparable to V’. ovalis or

[ 20 ]

V. majayensis has been detected, not even in Laguna Province,
the type locality of Blanco’s species.

In Petiver’s Gazophylacium (pl. 103, f. 4) a species of Vanilla
is figured which represents one of Camelli’s Luzon plants pub-
lished in Ray’s Historia Plantarum.

11. LECANORCHIS Bi.

The peculiar cup-like collar at the summit of the ovary beneath
the perianth is a remarkable character which is diagnostic for the
genus. About seven species are known. Lecanorchis japonica Bl.,
however, is probably only a variety of L. javanica Bl.

The range of the genus includes the Malay Peninsula, Perak,
Singapore, Siam, Japan, Java, New Guinea, and Borneo.

1. Lecanorchis triloba J. J. Smith in Bull. Dép. Agric. Ind.
Neérl. no. 19, p. 26. This is the only representative of the genus
at present known to be a native of the Philippines. Although
Smith has recently referred L. triloba to L. javanica Bl., because
of the likelihood of an incorrect diagnosis of the latter by Blume,
I have retained it here as the three-lobed labellum appears to
be a strong specific character and as my specimens agree with
L. triloba as described and figured by Smith. They do not agree
with the characters assigned to L. javanica by Blume.

The free portion of the upper sepal and petals is about 3 mm.
long. The obtuse petals are 3.5 mm. wide. From base of column to
the tip of the middle lobe, the labellum is about 4.5 mm. long.
The keel, which extends from the tip of the middle lobe to about
the middle of the disc, is only slightly elevated. The callus near
the base of the labellum is fleshy and distinctly two-lobed.

Didymoplexis philippinensis is very distinct from D. pallens,
the only other Philippine species, in having a three-lobed label-
lum.

The three-lobed labellum of D. philippinensis is an interesting
development. Dr. Schlechter has described two species from New
Guinea which also have the labellum three-lobed.

hundred and eighty species are valid. Spiranthes sinensis as at
present understood is a polymorphic species which has been
reported from Japan, China, Siberia, Afghanistan, India, Sunda
Islands, New Guinea, Australia, Tasmania, and New Zealand. A
critical study of specimens throughout the range may reéstab-
lish a few of the segregates which have been described. It must
not be overlooked, however, that several species of the genus,
which have been critically examined, not only extend over a vast
territory, but appear to adapt themselves to a wide range of
climatic and soil conditions.

Rich. According to geographical distribution the species of Ery-
throdes as understood by Dr. R. Schlechter are confined to the
eastern hemisphere and are in part distinguished by the bilobed
sac or spur of the labellum. Physurus L. C. Rich. in Mém. Mus.
Par. 4: 55 (1815) is a nomen nudum, consequently the name Ery-
throdes must be adopted for the genus. If Schlechter’s views
are upheld and we regard a bilobed spur in connection with
geographical distribution sufficient characterization for a genus,
then it becomes necessary to make nomenclatorial changes. But
it seems best to assign to Erythrodes all the species that have
been valid under Physurus, and to disregard the segregation pro-
posed by Schlechter.

Erythrodes Weberi is a near ally of H. Wenzelii, from which
it differs chiefly in the smaller flowers. The sac is not so deeply
bilobed as in #. Wenzeli, but too much reliance cannot be placed
on this character, as flowers from the same raceme are likely
to show wide differences in the apex of the sac.

in dried specimens is brownish. The bladder-like vesicles, one on
each side of the short conical spur, are concealed by the lateral
sepals. Each bladder contains a round wart-like excrescence.
The spur itself protrudes between the lateral sepals.

C. celebica Schlechter is a closely related species, with the tip
of the labellum dilated into a semiorbicular-reniform, obtuse
lobe. My specimens of C. celebica are from 10.5 to 14 em. high,
the aphyllous part of the plant not exceeding 6 cm. in length.

remains of the flowers. From dried specimens the leaves appear
to have been reddish beneath, very dark green above veined with

29. ADENOSTYLIS Bi.

Adenostylis strateumatica is the only Philippine species with an
extra-limital range. Specimens have been collected in Formosa,
China, Assam, Ceylon, India, Java, and Amboina. This is the
species on which Blume founded the genus Adenostylis.

Adenostylis by priority, if we follow the rules of nomenclature
adopted at the Vienna Botanical Congress, is the name of the
genus commonly called Zeuxine.

Adenostyles Cass (Bull. Soc. Philom. 1816) is a genus of the
Compositz, but has no power to eliminate Adenostylis, as the last
clause of Article 57 of the Vienna Code provides for the retention
of generic names when the difference in spelling lies in the ter-
mination, even though the termination differs by one letter only.
The examples given are Rubia and Rubus, Monochete and Mo-
nochetum, Peponia and Peponium, Iria and Iris. In Recommen-
dation xxx under Article 57,cases are cited where names differ in
spelling by one letter in or near the middle, and in such cases it
is recommended that the older name should be kept. Pluripeta-
lum and Pluropetalum is one of the examples given. Here might

[ 37 J

ORCHIDACEAE

be added Coryanthes and Corysanthes, genera of the Orchidacez
which are retained notwithstanding a perplexing similarity in
their spelling. According to this recommendation it might be
supposed that the point could be stretched so that Adenostylis
(1825) should yield to Adenostyles (1816), and that Zeuxine,
a generic name now preferred by authors for the species of Ade-
nostylis, should be kept in force, but in view of the very clear
and precise wording of Article 57 of the Vienna Code and the
examples given, it would seem that personal preference has
no weight in choosing the best course to follow, and that Adeno-
stylis, which differs from Adenostyles in its termination only,
must stand. Article 57 is here given in full:

Art. 57. The original spelling of a name must be retained except
in case of a typographic or orthographic error. When the dif-
ference between two names, especially two generic names, lies in
the termination, these are to be regarded as distinct even though
differing by one letter only.’

Examples: Rubia and Rubus, Monochete and Monochetum,
Peponia and Peponium, Iria and Iris.

Recommendations.

xxx. The liberty of making orthographic corrections must be
used with reserve, especially if the change affects the first syllable,
and above all the first letter of a name.

xxx1I. Many names differ by a single letter without risk of
confusion (ex. Durvillea and Urvillea). In cases where a close ap-
proach to identity is a source of error (Astrostemma and Aster-
ostemma in one and the same family, Asclepiadacez, Pleuripeta-
lum and Pleuropetalum in Orchidacez), only one, the older,
of the names should be kept, in accordance with Article 51, 4°.

33. TROPIDIA Lind.

Among the collections made for the Bureau of Science at Manila
there are several specimens of this genus in fruit or incomplete

temnervis Reichb. f. (Ptychochilus septemnervis Schauer) is known
to me only from the plate in Meyen’s Beitrage. Here 7. minor
may belong. 7. curculigoides Lindl. is cited by Naves. This species
is a native of Java, Borneo, and Malacca. It is not improbable
that Naves referred specimens, represented by one of the four
species in the following list, wrongly, to Lindley’s species.

Aside from the pair of supplementary carine in the middle
lobe the labellum is distinctly bicarinate. The median nerve is per-
haps thickened, but it is free from verrucose projections. The
lateral carinze are biseriate, that is, grooved with the edges of
the groove broken up rather regularly into short blunt teeth or
digitate processes. Ceelogyne palawanense is perhaps nearer to
C. Swaniana than to any other described species, but the form
of the middle lobe and the bicarinate disc are distinguishing
characteristics. In the specimens from which my description
was taken the flower shoot was much shorter than the leaves.

and in dried specimens the only trace of coloration retained is
the characteristic brownish marking found on the labellum of
Coelogyne sparsa and several other species of the § Lentiginose. C.
Loheri Rolfe (Kew Bull. 1908, 414) appears to be a closely related
species, but the leaves are much narrower in proportion to their
length and the disc of the labellum is traversed by five carine.

39. DENDROCHILUM B21.

Only two other Philippine orchid genera are richer in species:
Bulbophyllum with eighty-six and Dendrobium with eighty-
three. Dendrochilum has sixty-nine species.

Dendrochilum bistortum J. J. Smith from Maschate Island has
been referred to the Philippines. I have not seen any Philippine
specimens that match it.

Dendrochilum cucumerinum Reichb. f. 1 know only from cul-
tivated specimens. I have not seen any specimens of authentic
Philippine origin.

Dendrochilum grandiflorum Schltr. is known to me only by
the description and a flower from the type.

Dendrochilum longifolium Reichb. f. has been referred to the
Philippines by Krianzlin (Jagor 680), but I have not seen Jagor’s
specimens. D. /ongzfolium was not originally described from Phil-
ippine material.

Dendrochilum maleolens Krinzl. I know only from the de-
scription.

Reference should be made to OrcHIDACE, volume 2, for
detailed synonymy and descriptions of Philippine species of Den-
drochilum, and for a key to the species described up to 1905.

At the present time not less than one hundred and forty spe-

[2]

ORCHIDACEZ

cies of Dendrochilum are recognized. The Philippine representa-
tives may be distributed into four well-differentiated sections, as
follows:

A. Stelidia of the column obsolete.

a. Peduncles terminal. § Acoridium, 44 species.
b. Seape lateral. § Pseudacoridium, 1 species.
B. Stelidia of the column well developed, rarely rudimentary.
a. Scape lateral. § Eu-Dendrochilum, 1 species.
b. Peduncle terminal. § Platyclinis, 23 species.

Although § Acoridium is the largest section, only three species
referable to it were known prior to the American occupation of
the Philippines. Dendrochilum Merrillii, from Luzon, and several
species not known to inhabit the Philippines, such as D. Kingu
(Hook. f.) Pfitz., are characterized by the lack of stelidia on the
column, and yet show closer relationship with § Platyclinis than
with § Acoridium. These species constitute the § Aphanostelidion
proposed by Pfitzer.

The inflorescence is well developed while the leaf is expand-
ing, and in several plants which were examined the leaf was only
slightly longer than the sheaths when all but three of the flowers
were fully open. From Dendrochilum Hutchinsonianum, D. iri-
gense is in part distinguishable by the labellum, which is similar
to D. affine in the outline of the middle lobe. From D. pumilum
and D. affine it is distinguished by its larger flowers. From the
rich series of specimens gathered by Santos D. irigense appears
to be an extremely variable species in the size of the leaves and
pseudobulbs. Santos describes the flowers as yellow. Ramos de-
scribes them as being white. When dry the flowers are brownish
red.

Dendrochilum quadrilobum in general habit resembles D. par-
vulum and JD. tenue, but the structure of the flowers indicates
specific differences. The middle lobe of the labellum is larger than
the lateral lobes with a cuneiform open space at the tip which
gives a four-lobed appearance when taken in conjunction with the
lateral lobes. In both D. parvulum and D. tenue the middle lobe
hardly exceeds the lateral lobes. In D. guadrilobum, on the other
hand, the middle lobe conspicuously exceeds the laterals, giving
an aspect suggestive of the labellum of Malaxis quadriloba Ames.

Remarkable among the species which it resembles closely in
habit in having a reniform entire labellum. The three calli on the
disc are very distinct, one being in the middle of the depression of
the disc and one on each side of the depression near its margin.
That Dendrochilum reniforme is a close ally of such species as D.
microchilum and D. tenue is clearly indicated by two slight in-
dentations on the labellum in front, which if sufficiently de-
pressed would give the characteristic three-lobed labellum of
the Acoridium section of the genus.

Philippine Journal of Science (Botany) 4: 665 (1909) I discussed
the distinguishing characteristics on which Krinzlin placed em-
phasis, and decided to refer Philippine material to P. ventricosa
until a clearer case could be made for the retention of P. sesqui-
torta as a distinct species. In Fedde Rep. Beihefte 1:109 Dr.
R. Schlechter has adopted Smith’s conclusions after a study of
the type material at the Botanic Garden in Berlin.

41. CRINONIA BZ.
This is a small genus of four species. Krinzlin, in the monograph
of the Coelogynine in Engler’s Das Pflanzenreich, recognized Cri-
nonia as distinct from Pholidota. I have seen one representative
from the Philippines that appears to be an undescribed species.
A diagnosis will appear in Elmer’s Leaflets of Philippine Botany.

42. MALAXIS Sw.

Although the first published species of Malaxis was later referred
to Microstylis as Microstylis spicata Lindl., the laws governing
nomenclature necessitate the adoption of the name Malaxis to
designate generically all those species which are allied with ©.
spicata. In Nova Guinea, vu, Bot. 30, J. J. Smith has expressed
the opinion that Microstylis should be added to the list of genera
which are to be retained in spite of the laws of priority. But as
the original Malaxis was a true Microstylis and antedates Micro-
stylis, and as Microstylis was not included in the list of names
to be retained, sanctioned by the Vienna Congress and emended
at the Brussels Congress, Malaxis is the only name available.

[ 67 ]

ORCHIDACEA

Fawcett and Rendle in Flora Jamaica have adopted Malaxis as
the generic name of this group.

Probably not less than two hundred species are recognized.
Geographically the genus is most interesting, as its representa-
tives are found in the tropical and temperate regions of both
hemispheres. Thirty species are natives of the Philippines. Of this
number three are extra-limital. Malaxis biloba Ames has been
reported from Travancore, Himalayas, Khasia Hills, and Anda-
man Islands. M. flavescens Ames is a native of Java. M. latifolia
Smith has been reported from Java, Sumatra, Borneo, Celebes,
Singapore, Malacca, Siam, China, New Guinea, and Australia.

umn has the same hooked appendage on the back, only it is larger
in the Philippine species. The teeth on the labellum of M. tubu-
losa are unlike those of M. balabacensis, and the flowers show
slight differences which indicate specific distinction. Dfalaxis rhi-
noceros (Microstylis rhinoceros J. J. Smith in Bull. Dép. Agr.
Indes neérl. 22:21) is also closely related, but differs in part
through the very dissimilar petals.

In general habit Oberonza luzonensis resembles O. rosea Hook.
f. and O. masarangica Schltr., the latter, from Celebes, with nar-
rower leaves and looser racemes. Among Philippine species it
approaches most closely O. hispidula Ames, from which it is to
be distinguished by its looser racemes, smooth ovaries, and more
slender habit. O. luzonensis is a variable species in the size of the
leaves and stems. The form of the labellum is not dissimilar from
that of O. aporophylla Reichb. f.

reported from the Philippines. In previous publications I have
adhered to the generic interpretations of Pfitzer in my treatment
of these species. At present I am convinced that this treatment
necessitates an extremely artificial disintegration of a group
which is for all purposes best kept intact.

The Philippine plants which I believe represent L. parviflora
resemble the specimens, preserved in the herbarium of the Brit-
ish Museum, which Ridley referred to L. flaccida (Lobb 171,
Horsfield, Java). In my herbarium (12612) there is a specimen
collected by Weber (290) that resembles the specimen from Java
(Forbes) which Ridley in his monograph referred to L. parvi-
flora. This has an elongated, drooping inflorescence nearly 8 dm.
in length. L. parviflora is represented in the Philippines by the
following :

Luzon, Bontoc Subprovince, Father M. Vanoverbergh 1535, September

to October. Minpanao, District of Davao, C. M. Weber 290, November 14,

1911. I have also seen specimens from PottLto.

Also Java.

22. Liparis pectinata Ridley Journ. Linn. Soc. 22:277. The
labellum of this species is cuneate-oblong, or rather indistinctly
pandurate, with the truncate 3-3.5 mm. wide apex fringed or pec-
tinate. The labellum from base to tip is about 5.5 mm. long, with
a callus at the base. The type consists of a single specimen col-
lected by Cuming in the Philippines and now preserved in the
Lindley Herbarium at Kew. Aside from the type, with which,
unfortunately, I have not compared the material on which my
identification is based, the collections mentioned below are the
only ones I have seen. Undoubtedly a very rare endemic species.

Liparis pectinifera Ridley is a closely allied species from
Borneo in part distinguished by the absence of calli from the la-
bellum. This species is figured by J. J. Smith in Die Orchideen
von Java (f. ccr). L. punctifera Schlitr., a native of Celebes, from
the description is a closely allied species. L. Nakahara Hayata,
from Formosa (Icones Plantarum Formosanarum 4 : 29), is also
a close ally.

authentic material of L. tricallosa at Kew. On the type sheet in
the British Museum Herbarium there is a drawing of a plant in
flower from Buut Island, Sulu Archipelago, which in Reichen-
bach’s handwriting bears the name Liparis tricallosa. The actual
type consists of two flowering racemes and one fruiting. There
are no leaves or roots. Under these specimens is mounted a clip-
ping from the Gardeners’ Chronicle which bears Reichenbach’s
original description of the specimens ‘“‘introduced by Mr. Bull
from Borneo.” The nearest ally of this species from the Philip-
pines that I have studied among the specimens collected for the
Bureau of Science or by independent collectors is Liparis Elmeri
Ames, which has smaller flowers, and is more conspicuously stri-
ated on the labellum.

26. Liparis triloba #zd/. Journ. Linn. Soc. Bot. 22: 295. Ridley
described Liparis triloba from a Cuming specimen preserved in the
Lindley Herbarium at Kew. This specimen, of Philippine origin,
resembles very closely L. confusa, but is in part distinguished
by having the apex of the labellum entire. It also resembles
L. clavigera Ridl., the type of which is preserved in the British
Museum of Natural History. On the type sheet of L. clavigera
there is a note which reads as follows: “ Liparis triloba Cuming
Hb. Lindl.”

L. triloba appears to be much less common in the Philippines
than either L. confusa or L. parviflora. The specimens I have re-
ferred to it agree satisfactorily with the type in the Lindley Her-
barium as represented by a sketch in my possession for which
I am indebted to Dr. Prain, Director of the Royal Gardens,
Kew. The sketch shows a monophyllous stem which Ridley was
inclined to regard an exceptional condition, and which would
in fact be anomalous in the group to which L. tri/oba belongs.
But I have seen monophyllous forms of L. confusa mingled with
the characteristically diphyllous form. Lindley’s sketch of the
flower illustrates perfectly the flowers of the specimens gathered
by Whitford and Hutchinson.

The following collection appears to belong to L. triloba:

additional species are recorded, but insufficiently characterized.
Ceratostylis pendula Hook. f. (cf. Hook. Ie. Pl. 2100) is very
similar to C. philppinensis Rolfe. Probably the Philippine speci-
mens which have been referred to C. pendula are conspecific with
C. philippinensis.

About eighty species of Ceratostylis have been described. C.

ippines which has an extra-limital range. This species has been
reported from Borneo, Sumatra, Java, Malay Peninsula, Assam,
Khasia, and Sikkim.

48. AGROSTOPHYLLUM Bi.
Nine species are natives of the Philippines. In my herbarium
there is a fruiting specimen collected by C. M. Weber in Agusan
Province, Mindanao, on the west slope of Mount Hilonghilong,
at 419 meters altitude, no. 90, March 28, 1911, which is appar-
ently anundescribed species, allied with 4 grostophyllumcelebicum
Schltr. from Celebes, A. stipulatum Schltr. from Java, and A. tri-
jidum from Sumatra. It has a very much branched habit and the
leaves are quite distinct in outline from those of any of the species
named. The leaves are + 1.5cm. long, perceptibly narrower toward
the tip, about 38 mm. wide near the base, and at the apex bilobed
with awell-developed apiculate point to the midrib, which exceeds
the lobes. The sheaths of the leaves are bicuspidate as in A. cele-
bicum, A. stipulatum, and A. trifidum. Fruit hardly 1 em. long.

In most of the specimens examined the stems were very
short and greatly exceeded by the long gramineous leaves. The
structure of the labellum resembles that of Agrostophyllum glu-
maceum Hook. f. The epichile where it joins the sac is con-
tracted, with the margins inrolled to form a semitubular claw.
Over this claw extends the retuse continuation of the sac. The
epichile appears to arise from the base of the sac or hypochile.

Although only eight species have been reported from the Philip-
pines, an increase in this number is to be expected. From dried
specimens it is often impossible to make diagnoses, as the parts of
the flowers become agglutinated and torn. Consequently with-
out alcoholic material and detailed field notes it is difficult to
make satisfactory determinations. About fifty species have been
recognized from New Guinea, Java, Borneo, Perak, Amboina,
Burma, Celebes, Sumatra, Japan, China, Formosa, Fiji, Hong-
kong, Australia, and Ceylon. Phajus grandifolius has been col-
lected in tropical America, where it was originally introduced as

half inches from the base of the pedicel to the apex of the large
obcordate labellum. The labellum is 4 cm. long, and across the
widest part of the middle lobe it measures 2.8 em. The spur, 3 cm.
long, slender at its origin, and clavate below the middle, resem-
bling the abdomen of an ichneumon-fly, suggests a sabre as de-
scribed by Lindley. In dried specimens not unlike Phajus flavus
in aspect.

Calanthe hlacina Loher appears to be conspecific. I have not
seen the type of Loher’s species, but the figure and description
in the Gardeners’ Chronicle are sufficiently clear to warrant the

conclusion at which I have arrived.

The foliage of Plocoglottis Wenzelii resembles that of P. luc-

it is in part easily distinguished by the looser inflorescence, the
flowers of P. luchbanensis being crowded in anabbreviated raceme.
From P. bicallosum, P. Wenzelii is distinguishable by means of
its smaller flowers, very different labellum, and narrower leaves.
P. mindorensis Ames is a near ally, but differs in the foliage.

This is a large genus of over one hundred and eighty species, of

1. Eulophia dentata Ames in Phil. Journ. Sci. 6: 51. H. gra-
minea Ames non Lindl. OrcHIDAace# 2:166. The nearest rela-
tive of this species is 7. venosa Reichb. f., which is in part dis-
tinguished by the two carinz on the disc of the labellum. EF. b7-
carinata Hook. f., an Indian species, which is a member of the
group to which &. dentata belongs, is also characterized by a
bicarinate labellum.

A specimen of Hulophia dentata, which I originally referred to
E.. graminea Lindl. in my list of Philippine orchids in Orcut-
DACEZ 2 :166, was sent to me with a note which referred it, per-
haps because of the very glutinous substance prepared from its
bulbs, to Arethusa glutinosa Blanco. There is no doubt but that
Blanco gave special attention to useful plants, and his specific
name glutinosa may have been suggested by the use of the plant
for gluing boxes, violins, ete. It may be that Blanco’s species and
E. dentata are conspecific. Naves referred Arethusa glutinosa to
Geodorum nutans. Blanco’s reference to the use of the glutinous
substance prepared from the plant he described is a cause for the
suspicion that it includes #7. dentata.

2. Eulophia exaltata Reichb. f. in Bonpl. 5:38. Bletia stricta
Presl Rel. Haenk. 1:98. I have been unsuccessful in my efforts
to ascertain just what Philippine plant Pres] described under
Bletia stricta. By elimination, on the basis that everything in my
possession from the Philippines includes everything that could
by any possibility have reached Presl’s hands, Hwlophia exaltata
is indubitably the species in question. The long narrow leaves,
“2-3 nedes longa, ad 9 lineas lata,” are a strong characteristic of
E.. exaltata. The elongated scape, the simple lax raceme, the
floral bracts, broadly lanceolate, the lowermost up to 8 lines long,
the pedicels 8-10 lines long, the divisions of the perianth mu-
cronate, 10 lines long, the three exterior ones oblong-lanceolate,
the interior ones broader, the labellum erect and three-lobed, with
its subascending spur or horn 3 lines long, the rounded lateral
lobes and the rugose crest near the apex, are all descriptive of
F.. exaltata. The only discrepancies are the following: 1. “Perzan-
thium pallide roseum?” But Presl did not know the color. A guess
on his part should not be conclusive evidence that Bletia stricta
has been recorded only once from the Philippines. 2. Middle lobe
of the labellum ovate-obcordate. These words hardly describe
the middle lobe of E. exaltata, nor do they describe the mid-
dle lobe of the labellum of any species of Eulophia yet known
from the Philippines. An obcordate middle lobe immediately sug-
gests some species of Calanthe, but it is improbable that Ble-
tia stricta belongs to any genus other than Eulophia. Accord-
ing to my views it should receive the new combination-name
Eulophia stricta (Presl), with E. exaltata Reichb. f., E. ensiformis
Schltr., ZH. Leschenaultu Bl., and EH. Warburgiana Kranz. as
synonyms.

related, differing from H. Merrilii in only slight details, on the
sum of which I rely for specific distinction. Unfortunately H. Ver-
steegii is known to me only through the original description and

other close ally of Z. Merrillii is E. bicarinata Hook. f. This is
an Indian species, which is known to me through several spe-
cimens received from the Botanical Department of Northern
India. The flowers are much larger than in EL. Merrillii (labellum
1.7 cm. long in a specimen before me) and the racemes much
more densely flowered. 7. Versteegi appears to be intermediate
between the Indian and the Philippine species in the size of the
flowers. It may be found that /. papuana, EL. Versteegu, E. bi-
carinata, E. Merrill, and several other closely related species,
which have been referred to the synonymy of £. papuana, are
one and the same, representing a widely distributed polymorphic
species.

Dr. F. Kranzlin in his recent monograph of the Dendrobiine
(1910) admitted over six hundred species in the seven genera,
Dendrobium, Callista, Inobulbon, Sarcopodium, Diplocaulo-
bium, Desmotrichum, and Adrorhizon. In Dendrobium, as lim-
ited in the monograph, 571 species are given place. If we should
adopt the generic groups recognized by Krinzlin, the Philippine
species would be distributed among the following: Dendrobium,
Sarcopodium (Dendrobium acuminatum Rolfe, D. Lyon Ames,
D. stella siloe Ames), Diplocaulobium (Dendrobium Clemen-
ste Ames), and Desmotrichum (Dendrobium chrysographatum
Ames, D. Hurorum Ames, D. interjectum Ames, D. pseudocon-
vexrum Ames, D. purpureo-stelidium Ames, and several other
species).

Dr. R. Schlechter, in Die Orchidaceen von Deutsch-Neu-
Guinea, criticizes the Kranzlin monograph severely,and with the
exception of Cadetia keeps Dendrobium intact and expresses
the opinion that Adrorhizon Hook. f. does not belong to the

[ 106 ]

ORCHIDACEZ

Dendrobiine, but rather to Adrorhizine. Schlechter admits four
subgenera, as follows:

A. Leaves at the base without sheaths. 1. Athecebium.
B. Leaves on conspicuous sheaths.
I. Pseudobulbs or stems fleshy, or with a fleshy swollen zone.
1. Pseudobulbs or stems fleshy or thickened throughout their length.
2. Eu-Dendrobium.
2. Pseudobulbs or stems with only 1-3 fleshy, thickened internodes near
the base. 3. Rhopalolobium.
II. Stems wiry, dry, always very slender. 4. Xerobium.

SYNOPSIS OF THE SPECIES

AUTHENTICALLY REPORTED FROM THE PHILIPPINES

THE genus Dendrobium is of sufficient importance in the Philip-
pines to warrant an effort to distribute the species into groups,
according to their alliances, with brief characterizations. As a basis
of distribution I have chosen the sections admitted by Schlech-
ter in his studies of the orchids of New Guinea. From this ar-
rangement I have excluded doubtful species. In each section the
important distinguishing characters are printed in italics. Those
species which are described in this volume are marked with an
asterisk.

Schlechter’s arrangement is a very natural one. Although he
admits forty-one sections, of which sixteen are represented in
the Philippine Islands, it is much to be preferred to the briefer
arrangement adopted by Kranzlin in the monograph of the Den-
drobiinez in Engler’s Das Pflanzenreich. One cannot help but
feel, however, that Schlechter proposes an unnecessarily large
number of sections in his revisions of genera, and that his tend-
ency is toward complexity rather than simplicity, notwith-
standing his efforts to establish a workable system. His scheme
in Die Orchidaceen von Deutsch-Neu-Guinea is admirable, and

indicates tireless efforts to bring into conformity with modern
[ 107 ]

ORCHIDACE

botanical thought critical groups which have been neglected
until they present hopeless confusion to one who attempts to
understand them. His severe criticism of the Kranzlin mono-
graph, however, which opens the way to him for a new arrange-
ment of the species, although justified, does not take into account
the task which Kranzlin had to perform, and overlooks the sig-
nificant truth that Kranzlin in blazing the way for a comprehen-
sive treatment of the genus Dendrobium was overwhelmed by
the difficulties he encountered in laying the foundations for sub-
sequent monographers. At the same time Schlechter, in the pre-
sentation of his views relative to Dendrobium, is not beyond
criticism. In his Die Orchidaceen von Deutsch-Neu-Guinea, in
spite of his explanation of the forty-one sections into which he
proposes to distribute the species of Dendrobium (thirty of which
are accounted for by the New Guinea flora), he treats of 256
species, the greater part new to science, without a key to clarify
them. It is true that his sections indicate the systematic affini-
ties of his species, but even they fail to give the assistance they
should, as in his diagnoses, if such they may be called, he does
not make his points so clear that one not a student of the group
can understand them and apply them to species which are not
natives of New Guinea, or which are not cited in the work.

Subgenus ATHECEBIUM.

2. §DipLocauLosium. In the Philippine flora, if we except
D. longicolle Lindl., which I have not seen among the collections
I have examined, only one species of this group is known. It is
characterized by an elongated, rigid, unbranched, erect stem, at the
summit of which is a single, ligulate, leathery leaf. In the axil of
the leaf is an erect sheath from which the elongated slender pedi-
cel and its solitary purplish flower arises. The sepals are caudate.

stem between the pseudobulb and the rhizome is very slender.
Leaves, two at the summit, lanceolate, 1 dm. long. Flowers of brief
duration, not hairy.

The type sheet in the Lindley Herbarium bears two speci-
mens. The one that I understand to be the type is a small plant
with “three acicular leaves from the axil of the uppermost of
which springs the short peduncle bearing at its end a cluster of
small dry scales, from which proceeds a single yellowish flower
slightly tinged with pink.” This is the Loddiges plant referred
to in Lindley’s original notice of Dendrobium aciculare. The other
specimen on the type sheet bears three flowers on an elongated
leafless stem. A flowerless leafy stem from the same rhizome bears
four acicular leaves. This specimen is a counterpart of Dendro-
bum philippinense Ames. Kranzlin refers to Cuming 2112 and
Loher 487 as the Philippine representatives of the species. The
Cuming plant, numbered 2112, as I understand it, is the tall,
three-flowered one in the Lindley Herbarium which I regard
as distinct from the type. Loher’s 487 in the specimens I have
examined is flowerless, but is a perfect match in habit for speci-
mens of D. philippinense Ames. The labellum of D. philippinense
is not three-lobed. I have not seen any Philippine material refer-
able to D. aciculare.

Manila, but I do not find any authoritative source which warrants
such a statement. Under t. 6784 of the Botanical Magazine Sir
J. D. Hooker made the following significant statement: “It is a
remarkable fact that though first published forty years ago, the
native country of D. aduncum has hitherto been a mystery, Wal-
lich having sent it from India under the name it bears with no
further information.” The species is figured in King & Pantling’s
work on the Orchids of the Sikkim-Himalaya. I have not seen
any Philippine material referable to this species, and I doubt very
much if it has ever been found on the islands.

view absolutely defensible. The drawing of the labellum in the
original plate of 4. incrassatum, even with its supposed inaccura-
cies, is too much like the labellum of EZ. aporordes to be relied on
for specific differentiation. Schlechter’s treatment of E. aporoides,
for which he proposes a new section under Eria, is without
botanical support if we regard the number of pollen masses as a

generic difference between Eria and Dendrobium. E. aporoides
has four pollen masses cohering in pairs and is a true Dendro-

15. Dendrobium carinatum Willd. Sp. Pl. 4: 133. An unknown
species which Kranzlin referred doubtfully to § Aporum. All ref-
erences to this species agree in citing Petiver’s Bontia luzonica
as the type, but no adequate description was ever published. The
only satisfactory evidence as to the identity of the plant is Peti-
ver’s figure on Plate 44 of his Gazophylacium. This figure exhibits
a species of § Rhopalanthe, and suggests D. Robinsonu Ames. It
has the characteristic habit of D. crumenatum Sw., but the leaves
are terete and rigid. The likelihood of D. carinatum being con-
specific with D. Robinsoni is increased when the distribution of
D. Robinsonii, which is common in Luzon, is considered. In view
of Petiver’s figure I am unable to understand Kranzlin’s sugges-
tion that D. carinatum might be a representative of § Aporum.

cribes D. cerinum to the Sulu Archipelago, where it was collected
by Burbidge. Ridley regards this species as a variety of D. san-
guinolentum, at least he says that it is hardly distinct from
D. sanguinolentum var. cerinum. 1 have not seen any material

In the United States National Herbarium there is a specimen
from Loher’s collection bearing this number which is conspe-
cific with D. crumenatum Sw. Kranzlin also cites Cuming 2045
under D. cumulatum, but Cuming’s 2045 in the British Museum
is conspecific with D. crumenatum Sw. Under D. crumenatum
Krinzlin cites this Cuming number again. The question arises,
was Cuming’s 2045 a mixture of D. crumenatum and D. cumu-
latum? Even so, it is almost beyond belief that Loher’s 491 was
also a mixture of these two very dissimilar species. Such like-
lihood of confusion is scarcely borne out by the evidence that
D. cumulatum, if a Philippine species at all, must be extremely
rare. In the Gray Herbarium there is a specimen of D. cumula-
tum Lindl. from the Sikkim-Himalayan region, distributed by
King and Pantling, which is quite distinct from any Philippine
species of which I have any knowledge. Krinzlin’s citation of
specimens, which I regard as wholly incorrect, is the only evidence
of a Philippine origin for D. cumulatum which I have been able to
detect. I have included D. cwmulatum in this list simply for the
purpose of correcting what appears to be an extraordinary error
in citation of specimens in Krinzlin’s Dendrobiine (Engler’s Das

Pflanzenreich). It is very unlikely that D. cuwmulatum Lindl. is a
native of the Philippines.

In general habit Dendrobium Escritora resembles D. chryso-

base. D. chrysotainium, aside from the equitant leaves, agrees with
the species of §Rhopalanthe. The labellum is very obscurely
trilobed. In several flowers examined the lobing was obsolete,

This species was found mingled with specimens of Dendrobium

basal two-thirds deep purple. Through the basal portion of the
labellum run two raised lines which suddenly dilate at the base
of the midlobe into large deep purple lamellz. The midnerve of
the labellum is prominent.

Dendrobium leytense in general habit resembles D. piesto-

strongly complanate stems. The labellum is not at all fleshy, or
thickened at the tip, in dried specimens. Besides the type I have
examined many specimens collected by Wenzel (0415) in Leyte,
which bear flowers 1 cm. long with lips 9 mm. long. From the

Cuming’s no. 2057 is referred to this species in Vidal’s Phanero-

number to the Malacca collections, although the note on page 88
of Vidal’s list refers nos. 2053-2058 to the collections made at
Singapore. According to R. A. Rolfe (Journ. Linn. Soe. 21: 287,
and Kew Bull. 1908, p.119), Cuming’s nos. 2252-2399 repre-
sent the plants from Malacca. Rolfe also states that nos. 1-2252
were collected in the Philippines. Reichenbach described his
species from Cuming’s no. 2057, and gave the place of origin as
the Philippines. Hooker in the Flora of British India (5 :733)
cites Cuming without number and gives Malacca as a habitat.
Finally, Ridley, in his Materials for a Flora of the Malayan
Peninsula, refers the species to Malacca, and states that it is
endemic. I have not seen any Philippine material.

In the type the pseudobulb is covered by a thin grayish mem-

branches, at the base of which rootlets arise. The flowers are borne

on three branches and spring from a small scarious membranous
sheath. R. S. Williams 1934, which Krinzlin referred to Den-
drobium papilio Loher, appears to belong here. It has the same
habit as D. multiramoswm and a very similar labellum. D. Bluma
Lindl. and D. tenwicaule Hook. f. are near allies, but differ in
habit and in the lobing of the labellum. In the specimen col-
lected by Williams there are no rootlets on the lateral branches.

undoubtedly the variety striatum of D. O’Brienianum. Krinz-
lin referred D. striatum to the imperfectly known species in his
monograph. This species is known to me through cultivated
specimens only. In my herbarium there is a specimen from F.

In April, 1914, I wrote to Mr. Loher and requested him to send
me a traced sketch of the type of his species, or a fragment,
or information as to herbaria in which the type or co-types could
be found. Up to April, 1915, no reply from Mr. Loher was re-

ceived. The identity of D. papilio has been a puzzle, and to make
matters worse Krinzlin in his monograph cited only one speci-
men under it, a plant collected by Williams (1934), which accord-
ing to material in my herbarium is in no way comparable with
D. papilio, if D. papilio and D. Vanoverberghi are conspecific.
Krinzlin had not seen the type, but his citation of specimens
being that of a monographer, was to my mind conclusive. His
description agreed with my duplicate of Williams 1934. In the
original description of D. papilio in the Gardeners’ Chronicle,
D. papilio is ascribed to § Crumenata and characterized as very
much branched. Mr. Loher wrote in his letter of April, 1914, that
the original description should be emended so that the word
“multicaule” becomes “ramosissimum.” In the original descrip-
tion of D. Vanoverberghi the racemes were characterized as one-
flowered. From the very clear photograph reproduced in Plate
xm of the Philippine Journal of Science the flowers appear
to be solitary. In my herbarium there is a fragment of a speci-
men preserved at Kew for which I am indebted to Sir David
Prain. Mr. Rolfe has referred this specimen to D. papilio Loher.
Krinzlin wrote in his monograph, “Species haud bene nota.”

58. Dendrobium planibulbe Lindl. in Bot. Reg. (1843) Mise.

the base they are bulbous, flattened,and about 3 cm. long by 1 cm.
wide, above the bulbous portion the stem becomes slender again
and bears about eight oblong emarginate leaves, 3.5 cm. long by
7 mm. wide; the upper portion of the stem above the leaves is
naked and flower-bearing. Flowers 12 mm. across, white. Petals
5 mm. long, the margin somewhat shortly fringed. Labellum
about 8 mm. long, cuneate at the base, three-lobed; lateral lobes
equalling the fringed middle lobe; middle lobe 2 mm. long, trun-
cate in front, at the base provided with a three-pointed callus. The
specimens before me are from 8-34 cm. tall. D. planibulbe has
been confused with D. Blumu Lindl., a Javan species. The mid-
dle lobe of the labellum is hardly linear as described by Lindley.
D. tuberiferum Hook. f. Ic. Pl. t. 2025 is a near ally of D. plani-
bulbe, but differs from it in the middle lobe of the labellum.

Between this species and a cultivated specimen from the Buit-
enzorg Botanic Garden identified by J. J. Smith with D. flabel-
lum Reichb. f. there are slight differences which are surely too
inconsequential for specific differentiation. In the specimen from

[ 132 ]

ORCHIDACE#

Java there is a very inconspicuous straight keel between the
two undulate carinae which traverse the lower half of the middle
lobe of the labellum. In the Philippine specimen taken for com-
parison there are three undulate carine that extend beyond the
centre of the middle lobe, the centre one of which in Weber 79
from Mindanao extends nearly to the tip of the lip in a broken
chain of wart-like calli. Counting the bilobed ears as two teeth
and the filament as one tooth, the column is five-toothed, but in
dried specimens this character is difficult to study. In alcoholic
material prepared for me by Weber the lateral lobes of the col-
umn are emarginate rather than bidentate. The truncate emar-
ginate-apiculate apex of the lip in the Philippine species is nar-
rower than the middle, whereas in the Javan specimen the apical
portion exceeds the posterior in width. As a result there is a
slight difference in aspect, but this difference may not be con-
stant, and would hardly prove diacritical in such a variable part
of the flower. The differences in habit are slight and perhaps
individual rather than specific. Dendrobium Kunstlert Hook. f.,
according to the plate in Hooker’s Icones, has three undulated
keels and in these agrees with the Philippine plant. J. J. Smith
regards Hooker’s species as identical with D. flabellum. D. pli-
catile is the D. Macra@i Lindl. of my earlier lists of Philippine
orchids. In the Gray Herbarium there is a specimen from the
vicinity of Manila, Luzon, which Reichenbach f. compared with
D. Scopa Lindl., that appears to be the same as D. plicatile.

Among the Philippine species of Dendrobium examined this
one seems most likely to be the normal form of D. pseudaclinia
Lindl. In the absence of positive information, however, it is best
to treat the plant as a distinct species.

I have not seen any leafy stems. My description of the leaves
is drawn from an excellent photograph preserved with the type
in the Bureau of Science Herbarium. The labellum lobes are all
directed forward, the lateral ones slightly divergent. Only the
lobes are ciliate or fringed. From the flowers examined it would
seem that the middle nerve of the labellum is more prominent
than the other nerves.

D. Aclinia Reichb. f. in Bonpl. 4: 329. To this interesting spe-
cies I refer specimens from Luzon. D. pseudaclnia is anomalous
among Dendrobiums. It belongs to a group of about four species,
which agree in detail with Griffith’s Aclinia. The sepals, petals,
and labellum are similar, about 1.2 cm. long by 2-3 mm. wide.
There is no mentum. The stout column is quadridentate, the
posterior tooth bearing the anther, the anterior one arising from
the region of the rostellum. In dried specimens the flowers are
yellow and are described as yellow by the collector. The stems
are slender, somewhat fractiflexed, concealed in dried specimens
by loose, scarious sheaths (leaf bases). The flowers are borne in
twos or threes on the leafless stems. The leaves are subcoria-
ceous, distichous, oblong, acute, tapering at both ends, about
6 cm. long by 1 cm. wide.

A cultivated specimen under observation at Manila failed to
expand its flowers. Mr. Merrill of the Bureau of Science described
this specimen as follows: ‘‘ Calyx 2.e. pedicel and ovary green,
corolla straw colored. Have seen no open flowers in the two
months the specimen was in flower. It may open at night or very
early in the morning, or possibly does not open at all. Flowers
from leafless branches, usually two, each with long pedicel on a
very short common pedicel.”

Reichenbach informed Lindley that he had seen specimens
from Manila.

The type consists of a single plant. The habit suggests the
groups to which Dendrobium angustifolium, D. pseudoconvexum,
and D. Eurorum belong. The flowers are much smaller than in
D. pseudoconvexum, and are well characterized by the callus on
the labellum, which is flat, spool-shaped, and tinged with purple
on the lateral ends. There are no longitudinally placed carine as
in D. pseudoconvexum. The column is provided with two subu-
late stelidia, one on each side at the summit in front. On the pos-
terior side, at the base, each stelidium is unidentate. The stelidia
even in dried specimens are of a deep magenta purple color. The
nearest affinity of this species is D. parietiforme J. J. Smith, from
which it differs in the absence of lobes at the tip of the labellum.
The labellum of D. parietiforme is fleshier and between the ter-
minal rounded lobules distinctly apiculate in the specimen I have
examined.

Dendrobium unicorne is a near ally of D. parietiforme J. J.
Smith from Celebes. It is distinguished from that species by the
more deeply bilobed apex of the labellum, by the obscure lateral
lobes, and by the horn-like projections on the callus that stand
in front of the opening to thesac. The labellum in D. parietiforme
is much more fleshy than in either D. wnicorne or D. purpureo-
stelidium, and is distinctly apiculate. The column of D. wnicorne
is entire at the tip with a large membranous hood partly sur-
rounding the androclinium. The flower arises from the pseudo-
bulb at the back of the leaf.

What appears to be the same species is represented in the
herbarium of the Bureau of Science by a single specimen.

ORCHIDACEH

in Bull. Herb. Boiss. 2d ser. 6 : 458 (1906). For a fragment of
the type accompanied by analytical drawings I am indebted to
Dr. Schlechter. D. Usteri is a member of § Rhopalanthe with
terete leaves. In my herbarium this species is represented by
several specimens collected by W.S. Lyon on Guimaras Island,
between the islands of Panay and Negros. D. Usteri was origi-
nally collected in Negros, where it was found growing on man-
groves.

The flowers on my specimens average larger than those de-
scribed from the type by Schlechter, the labellum in one flower
measuring 1 cm. in length. The lateral sepals and petals resemble
the sketches prepared for me by Schlechter, but the upper
sepal in my material is narrower than that of the type, measur-
ing 8mm. by 2.5 mm. Mr. Lyon describes the flowers as yellow
“veined with pale rosy lines.” In outline the labellum suggests
D. crumenatum. The pseudobulbs are from 3.5 cm. to 5 em. long,
deeply grooved longitudinally in dried specimens, and are ter-
minated by a fleshy terete sharply pointed rigid leaf and by the
slender flower shoot. The flower shoot is longer or shorter than
the leaf, in one specimen slightly exceeding 1.5 dm. in length. The
-longest leaf hardly exceeds 8 cm. in length. In the specimens
examined the flower shoot exceeds the leaf in five plants and is
shorter than the leaf in four.

Dendrobium Usterioides is a close ally of D. Usteri Schitr.,
differing from it in the stouter pseudobulbs, and in having the
flower shoots much shorter than the fleshy leaves. In D. Usteri
the middle lobe of the labellum is oblong-quadrate, hardly if at
all dilated near the tip. In his field notes which accompany speci-
mens of D. Usteri Mr. Lyon wrote: “This Dendrobium in habit
of growth and leaf, but not in inflorescence, much resembles my
no. 22 [ D. Usteri]. Flowers paler yellow and exterior of perianth
veined with pale rosy lines.”

The immature pseudobulb and leaf are for the most part con-
cealed by about three loose, tubular, whitish sheaths, which soon
pass away (?). The mature pseudobulbs are yellowish, either wholly
or in part clothed with a closely appressed grayish covering. The
inflorescence is also covered with whitish or grayish sheaths

before the period of anthesis begins. In mature specimens the
remains of these sheaths may be detected after anthesis.

Among Philippine species of Dendrobium heretofore described
Dendrobium Wenzel is readily distinguishable by means of the
terminal pair of orange-colored glossy leaves, between which the

inconspicuous flowers appear, usually one at a time. Mr. Wenzel
describes the flowers as white, purple, and yellow. From dried
material the sepals and petals appear to have been white, the
labellum purplish with a yellow tip.

I have seen specimens without flowers, collected in Mindoro,
which may be conspecific with D. Wenzel. From Mindanao I
have material, also without flowers, which represents a species
closely related to D. Wenzeli, but stouter in all itspartsand much
branched. In the Bureau of Science Herbarium at Manila there
is a single specimen (H. N. Whitford 806) from the Province of
Tayabas, Luzon, that appears to be conspecific with D. Wenzelit.
There are no flowers with this specimen, which in general habit
resembles an undescribed Dendrobium from Bangarmassing,
Borneo (J. Motley 722), preserved in the Kew Herbarium.

In 1909 Dr. Robert G. Leavitt prepared a descriptive list of

201-244 (C) Bot.). To this list he admitted forty species, all but
six of which were thought to be endemic. Probably three hundred
species constitute the genus. In the monograph prepared for
Engler’s Das Pflanzenreich, Kranzlin recognized § Trichotosia as
a genus. This treatment is hardly commendable. In the follow-
ing list Trichotosia is kept as a section.

from Leavitt's description of the type of Z. Copelandii. The
measurements given agree almost point for point with Leavitt's
measurements, and are not in agreement with Rolfe’s in the
original description of £. formosana. It would seem that Kriinz-

from the type of . Copelandii (Copeland 1423) which was loaned

This species is closely related to Hria leytensis Ames and E.
fusca Bl. From the former it is in part distinguished by its less
strict habit and by the deeply retuse, reniform middle lobe of the
labellum. F.. leytensis, in dried specimens, is less pubescent and
on the under side of the mature leaves appears to be smoother
than E. lagunensis. E. fusca is in part characterized by having a
tricarinate labellum. In several flowers examined the petals were

[ 151 ]

provided with one or two marginal hairs, but in no case were
hairs numerous. In both #. lagunensis and E. leytensis the label-
lum is pubescent, but much more so, especially toward the base,
in the latter than in the former. In both species, in the centre
of the disc just above the keels, the mid-nerve is thickened and
densely pubescent.

From Eria halconensis Ames, LH. McGregorii is easily distin-
guished by its larger flowers. From EH. odorifera Leavitt, where
dried specimens are considered, it is separable by the verrucu-
lose foliage and closely appressed rather than spreading pubes-
cence. It also differs from H. odorifera in its denticulate labellum
lobes and in its longer racemes. In proposing McGregor’s mate-
rial for specific rank I have relied wholly on dried specimens and
on a careful study of the types of EH. halconensis and E. odori-
Sera, which among the species of §’Trichotosia appear to be most
closely allied with HL. McGregorii.

The Trichotosia section of the genus Eria is at present known
to contain nine species which are natives of the Philippine Is-
lands. With the exception of H. Ramos Leavitt, a dwarf species
with distinctly creeping habit and with small leaves about 8 mm.
long, they are extremely difficult to differentiate if reliance is
placed on descriptions alone. The following key, based on a re-
study of herbarium material, is offered with the hope that it may
show the important characteristics serviceable for differentiation

Eria zamboangensis is a near relative of E. cymbiformis J. J.
Smith, from which it is readily distinguishable by means of
the entire labellum. From 2. palawanensis Ames, which has an
entire labellum, it is in part distinguished by its much broader
leaves. The central callus on the labellum is very fleshy and ter-
minates rather abruptly. The lateral calli or keels are membrana-
ceous and in dried specimens lie flat, the margin overlapping the
margin of the labellum. At the apex each keel is free and from
the material examined appears to be thickened and tubercular.

65. BULBOPHYLLUM Thou.

This is a vast genus, which contains approximately seven hundred
species. As at present understood, it is the richest in species of all
orchid genera. Eighty-six members of the genus have been re-
ported from the Philippines on reliable information. To this num-
ber one might add at least a dozen species which have been cred-
ited with Philippine origin, but which are undoubtedly extra-lim-
ital. ‘The section Racemosz, represented by forms which belong
to Schlechter’s § Aphanobulbon, is characterized by the absence
of distinct pseudobulbs, and is one of the largest sections in the
Philippines. A key to this section was published in the Philippine
Journal of Science (7 :128), which includes all species described up
to August, 1912, to which a Philippine origin could be assigned.

ORCHIDACE

In the following list no attempt has been made to separate Bul-
bophyllum from Cirrhopetalum. The section Cirrhopetalum is
characterized usually by an umbel-like inflorescence and united
lateral sepals. Schlechter recognizes Cirrhopetalum. J. J. Smith
in his Die Orchideen von Java united it with Bulbophyllum. I
am not prepared to adopt the view which upholds the section as
a distinct genus, although I agree with Dr. Schlechter that there
are several reasons why Cirrhopetalum would be better treated
as a distinct group. Most of the species are very easily recognized
through their appearance and floral structure, and with the ex-
ception of a few species are separable from Bulbophyllum at a
glance. In my own herbarium I keep all Cirrhopetalum species
under separate covers, which practice is an admission of the
convenience experienced by the recognition of a clearly charac-
terized group. But until Bulbophyllum is taken in hand by the
monographer and thoroughly studied, a work which must soon
be undertaken, I am inclined for purposes of publication to keep
Bulbophyllum and Cirrhopetalum inseparable.

1. Bulbophyllum adenopetalum Lind. in Bot. Reg. (1842) Mise.
85. B. anguipes Schltr. from Celebes is a near ally of this spe-
cies. In Phanerogame Cumingiane Philippinarum Cuming’s
2076 is referred to Bulbophyllum penicillium Par. and Reichb. f.
I have seen a duplicate of this number preserved in the herba-
rium of the British Museum of Natural History which is referable
to B. adenopetalum Lindl. (as that species is at present under-
stood), and in no way comparable with B. penicilliwm, a species
that I have not seen among the Philippine species I have ex-
amined. In my herbarium there is a note which accompanies
a specimen of Merrill’s 3853. This note I made at the British
Museum of Natural History, and it reads as follows:“ Proba-
bly near Bulbophyllum penicillium, Cuming 2076 Ins. Philipp. in

Brit. Mus.” Under this note is written, “ Not B. penicilliwm.” In
my note-book there are sketches of drawings in color by Lind-
ley of B. adenopetalum from Singapore, designated as follows:
“Singapore Loddiges no. 177, Oct. 10, 1842.” My notes are as
follows: “These drawings occur on a sheet which carries two
Philippine species collected by Cuming. They [the plants] may
match Merrill’s 3853 in my herbarium. They have a similar leaf!
I take it that these are type specimensof Lindley’s Bulbophyllum
adenopetalum. There are no other sheets representing the species
in his herbarium.” Lindley’s sketches agree in essential details
with the flowers of Merrill’s 3853. Lindley’s description in the
Botanical Register (1842) Misc. 85, was prepared from speci-
mens imported by Messrs. Loddiges from Singapore. This de-
scription agrees very well with the Philippine specimens in the
Lindley Herbarium.

In the Flora of British India (5: 770) Sir J. D. Hooker placed
B. adenopetalum under species excluded and unknown with the
following brief note: “2. adenopetalum Lindl. in Bot. Reg. 1842,
Mise. 85, which was supposed to be a native of Singapore, is
a Philippine Island species.” In the sixth volume of his Flora,
on page 188, I find the following: “'T'wo different Philippine
species in Hb. Hook. and in Hb. Lindley, both labelled by that
author B. adenopetalum, led me to suppose that the latter had
been erroneously attributed to Singapore, whence my exclusion
of it from the Flora.”

The type of B. adenopetalum may have come from Singapore,
and may be unlike the Philippine specimens later referred to
it. Ridley in his Materials for a Flora of the Malayan Penin-
sula does not help us to a solution of the problem; he includes
B. adenopetalum among the species cited, but his reference to
distribution adds another perplexing question. It is as follows:

In my herbarium there is a duplicate of Elmer’s 7572 from
Luzon which Dr. R. Schlechter referred to B. adenopetalum
Lindl. Reichenbach f. cited B. adenopetalum as a near ally of the
Philippine B. braccatum.

For the present it seems best to await more complete informa-
tion before abandoning the name B. adenopetalum for the Phil-
ippine species represented by Cuming 2076 and Merrill 3853.

the collection of Consul Schiller, and stated that the Philippine
origin of the species was by no means sure. Plate 157 of Xenia

lichen Pflanzenfamilien based his section Balznoidea on this spe-

In Kew Index B. baleniceps is referred to B. Napelh Lindl.,
a species which was described in 1842 from material collected
by Descourtilz in Brazil. The specific name, “ Napelli,” was sug-
gested by the resemblance of the flower to Aconitum Napellus.
Under this species in Martius’ Flora Brasiliensis, Cogniaux does
not cite B. baleniceps in the synonymy of B. Napelli.

species of Bulbophyllum reported on reliable authority to be na-
tives of the Philippine Islands. In this list B. Blume was included,
although no material of Philippine origin had passed through
my hands. Since my list was published I have examined a series
of specimens from Leyte which correspond, so far as the details
of the flower are concerned, with a specimen in the herbarium of
the Bureau of Science sent from Java by J. J. Smith and referred
by him to B. Blumei. This specimen consists of a single flower
and lacks both pseudobulbs and leaves. My specimens also agree
with the figure published by Smith in his supplementary plates
to Die Orchideen von Java.

In my herbarium there is a sketch of the type of Lindley’s
Cirrhopetalum maxillare (Bulbophyllum mawillare Reichb. f.),
which resembles so closely the specimens which I have referred to
B. Blumei that I am inclined to believe that Lindley’s plant may
prove to be conspecific with B. Blume. The flower of B. Cheiri
Lindl. resembles B. Blumet. Lindley’s sketch of the labellum
resembles very closely the form of the labellum of B. Blumei.

the other details of structure are in pretty close agreement with
the analysis of Bulbophyllum elongatum. I have referred B. gigas

The elongated scapes, which are about twice as long as the
leaves, with the flowers 6—7 mm. apart in slender racemes, give
to Bulbophyllum Escritoru a very characteristic appearance. B.

closely allied to B. E’scritora of all known Philippine species.
B. Vanoverberghii has much broader leaves and is easily distin-
guishable by means of its different inflorescence. The elongated
scapes of B. Escritorii and the less acuminate lateral sepals

Bulbophyllum leytense is a member of the puzzling group to
which B. dasypetalum Rolfe and B. Vanoverberghi Ames be-
long, a group without the well-developed pseudobulbs that char-
acterize the section Aphanobulbon proposed by Schlechter. The
inflorescence is much shorter than the leaves; the scape below
the raceme is concealed by inflated, loose, imbricating sheaths.
In B. Vanoverberghi and B. dasypetalum the scape normally
exceeds the leaves in length and lacks, at least when mature, the
distinctive appearance caused by the imbricating bracts of B. ley-
tense. Another characteristic of B. leytense which is serviceable
for purposes of identification is the elongated labellum, which is
4 mm. long from the tip to the point where the sides become
conduplicate.

The pseudobulbs and leaves resemble Bulbophyllum uniflorum
Hassk. Among the species of the section Sestochilus now known
to be natives of the Philippine Islands B. maculosum is distin-
guishable by means of its elongated pseudobulbs, which are longer
than the flower scapes, and by means of the greenish-yellow, con-
spicuously spotted sepals and petals.

cushion-shaped thick base, and a tongue-shaped, fleshy, acute,
straight apex. The column is at each side produced into a long
bristly acute tooth. The flowers are comparatively showy, the
sepals and petals being yellowish-green, with numerous brown

This is an ally of Bulbophyllum ornatissimum and B. Colletti,
from both of which it is quite distinct. The very odd, feather-
like processes on the petals (which are brilliant carmine in color,
nearly 2 mm. long, and shortly stalked) are found in no other
Philippine species. They look exactly like little feathers, or like
the divisions of the plumes of Celosta plumosa, and are about
twenty in number on the upper margin of the inconspicuous
petals.

the upper sepal attain a length of 2 mm. The elongated seti-
form tips of the upper sepal, which is about 2 mm. long with sev-
eral hairs originating from it, suggests B. trisetum, but from that
species the details of the column easily separate B. stramineum.

In habit Octarrhena gemmifera resembles Phreatia luzoniensis
Rolfe more closely than any other Philippine species. The bracts
of the inflorescence, however, are serviceable for purposes of
separation. In P. luzoniensis the bracts are lanceolate and hardly
embrace the pedicels of the flowers, whereas in O. gemmifera the
bracts not only enclose the pedicels but embrace the rhachis of
the inflorescence. Among the specimens examined, the plants in
flower hardly exceeded 2cm. in height. Plants with fruit or flower-
less racemes measured 8 em. in height. Octarrhena Amesiana is a

[ 193 ]

larger, more robust species. The caulescent habit, footless col-
umn, and general aspect suggest Octarrhena. Although through
its caulescent habit quite distinct from them, O. gemmifera re-
sembles Phreatia secunda Lindl. and P. brachystachys Schltr.
It is among the smallest species of either Octarrhena or Phrea-
tia, and much smaller than any of the specimens of P. secunda or
P. brachystachys 1 have examined.

Five Philippine species have been recognized. Thelasis is made
up of two distinct sections, Kuphroboscis and Oxyanthera, which
are separated by vegetative characters. §Euphroboscis includes
those species which have a conspicuous pseudobulb and a fleshy
leaf. §Oxyanthera has a flattened pseudobulbous stem which is
concealed by the equitant spreading leaves. Dr. Schlechter up-
holds §Oxyanthera as a distinct genus. Twenty or more species
of Thelasis have been described.

inconsequential. 7. alata has been reported from Java, Borneo,
etc. In the Orchid Review (20 : 237) an interesting account of
Thecostele is given by R. A. Rolfe.

Patawan, LEYTF.

71. GRAMMATOPHYLLUM BI.
The extent of the synonymy in comparison with the number of
species is surely an indication that variation is characteristic of
Grammatophyllum. Four or more species have been ascribed to
the Philippines, but only three of these are known to me. They
appear to be quite distinct. Grammatophyllum Measuresianum
has been referred to the synonymy of G. Fenzlanum Reichb. f.,
and G. Fenzlianum has been referred to the synonymy of G.
scriptum Bl. In Die Orchideen von Ambon J. J. Smith sug-
gested that perhaps G. scriptum and G. multiflorum are forms
of the same species. It is not unlikely that G. Measurestanum, as
Sir Joseph Hooker suspected, is merely a garden form of G.
Fenzhanum. G. Fenzlianum is a near ally of G. Rumphianum.
J. J. Smith has referred both to the synonymy of G. scriptwm in
Die Orchideen von Ambon.

A specimen in fruit described by the collector as a gigantic
orchid is the only material in the Bureau of Science Herbarium
referable to this species. I submitted the specimen in question to
Sir David Prain, who kindly reported as follows: “The fruiting
specimen received for determination is a Grammatophyllum, and
is believed to be G. Wallisu Reichb. f. in Linnea, 41 : 107. This
species was described from dried specimens collected at ‘Manilla’
by Wallis, and to it a flowering specimen collected by Loher at
Tayabas in June, 1904, has been referred. The fruiting specimen
agrees quite well with this so far as comparison is possible.”

Grammatophyllum Wallis is known to me only from the
original description and the fruiting specimen in the Bureau of

Apparently a near relative of Thrixspermum Raciborsku J. J.
Smith, and of 7. longicauda Ridl. which has smaller flowers and
a labellum without a median fleshy callus. The flowers usually
open singly throughout a long period of anthesis, the rhachis elon-
gating until the last flower appears. Each flower lasts only a day
or two. In several specimens examined three flowers were open
at one time on the odd bracteate rhachis, which in 7. elonga-
twm resembles in outline a slender plant of Oberonia anceps. The
stems appear to be scandent, and even near the tips stout whitish
roots burst through the leaf sheaths.

There are several species of § Orsidice which are very near this
one, but from the material I have studied differences exist which
to my mind indicate specific dissimilarity. The ephemeral nature
of the flowers of all these species is accountable for the fact that
in herbaria one rarely finds complete specimens.

To Thrixspermum elongatum specimens collected by C. A.
Wenzel in Leyte may be referred. Under the field number 095
Wenzel assembled many fragments of several plants. The leaves
of some of these fragments exceed 1.5 dm. in length, and the in-
florescence bears flowers that are about 5 cm. long. The conclu-
sion to be drawn from this material is, it seems to me, that
T. clongatum is a variable species.

In Petiver’s Gazophylacium, plate 1038, fig. 8, this species is
probably represented and was prepared from one of Camelli’s
specimens referred to in Ray’s Historia Plantarum.

The material on which the above species is based is not all
that one might wish for the preparation of a detailed description,
but is sufficiently characteristic to make the new species readily
distinguishable from all other members of the section Orsidice
known to be natives of the Philippines. The middle lobe of the
labellum is difficult to make out in dried specimens. On the front
wall of the sac there is a conspicuous mass of fine, delicate hairs
along the perpendicular median line.

The labellum recalls that of Sarcochilus hirtulus Hook. f.
(Ic. Pl. 2121), but the posterior lobes are larger than the anterior
lateral lobes, the middle or terminal lobe is densely long hairy
on the margin, as in Dendrobium scopa Lindl., and in place of
a distinct sac there is merely a depression of the disc. The habit
is also suggested by Sarcochilus hirtulus, but in Thrixspermum
quinquelobum the leaves are narrower, usually conduplicate (in
dried specimens), and the bracts recall those of the raceme of
T. pardale Schitr.

In the structure of the flower Thrixspermum Robinsonit is very
similar to 7. Vanoverberghi Ames. The vegetative characters,
however, are a simple means for distinction. In 7. V anoverberghu
the leaves appear to arise more or less from the same place and
ascend obliquely, whereas in 7. Robinsonw the leaves are dis-
tinctly distichous and spread horizontally. The structure of the
labellum in both species is similar. Whether or not the vegetative
distinctions are constant it is quite impossible to determine from
the material I have examined.

The material from which the description was prepared consists
of several inflorescences, two leaves, and four flowers.

From Thrixspermum elongatum Ames, to which 7’. rostratum
is closely allied, it isreadily distinguished by the long, strap-shaped
leaves, and by the elongated beak-like middle lobe of the cinna-
bar red labellum. As in the other species of this section of Thrix-
spermum, the rhachis of the inflorescence elongates during an-
thesis, producing short-lived flowers, for the most part one at a
time, throughout several weeks. The shortest rhachis in the type
specimen bears about eighteen floral bracts and is hardly 9 cm.
long. The longest rhachis bears about eighty floral bracts and is
36.5 cm. long.

76. SARCOCHILUS R. Br.

Of the nine species known to be natives of the Philippines, six
are endemic. By some authors Sarcochilus and Thrixspermum
have been regarded as congeneric. The modern tendency is to
keep them distinct. The chief difference between them is found
in the labellum, which in Sarcochilus is movably articulated with
the column, while in Thrixspermum it is rigidly attached. The
sac of the labellum in Thrixspermum has a wide opening, and
is not, as a rule, terminated by a more or less porrect anterior
utricle.

Although Sarcochilus calceolus Lindl. was originally reported
as a Philippine plant, I have not included it in this list, as there
is an element of doubt about it. 8. calceolus is common at Singa-
pore, and it is not improbable that the Cuming plant described
by Lindley was collected there and not at Manila.

Sarcochilus compressus Reichb. f. in Walp. Ann. 6: 498 has
been reported from the Philippines.

Sarcochilus croceus Lindl. in Bot. Reg. (1846) 32: sub t. 19
was described from a single leaf and a flower bud sent to Lindley
by Messrs. Loddiges. I have been unable to recognize it among
the specimens I have examined.

I have referred this species to Sarcochilus not without doubt
as to the correctness of my diagnosis of its generic characters.
With the exception of the callus on the front wall of the spur,
which appears to be partly formed by the inflection of the nearly,
or almost entirely, obsolete middle lobe, the labellum is smooth.
The column is scarcely developed into a foot and the labellum
joins it without articulation.

The flowers suggest those of Sarcochilus Teysmannu J. J.
Smith in the general form of the labellum. The inflorescence is
branched with the branches branched again. Flowers and fruits
are present at the same time. The first branch springs forth about
4 cm. above the leaves. The branches in dried specimens are con-
spicuously two-winged. The claw of the labellum forms a wide
canal, with erect sides, which leads into the saccate termination;
the lateral lobes rise perpendicularly above the very small, some-
what thickened middle lobe, with their acute tips pointing out-
ward from the column. Seen from the side the sac and lobes
suggest the head of a horse with erect ears.

78. PHALAINOPSIS Bil.

This is a genus of showy orchids which is of horticultural impor-
tance and consequently very difficult to systematize. Numerous
varieties have been described for horticultural purposes which de-
pend largely on color, size, and form, characteristics impossible
to distinguish in dried material. In the following list no attempt
has been made to differentiate between forms which are purely
horticultural. An instructive paper on Phalaenopsis was published
by R. A. Rolfe in the August number of the Orchid Review for
1905, in which references are made to Philippine species. I have
marked with an asterisk those species that have not been repre-
sented in collections made for the Bureau of Science, and which
are known to me only through cultivated specimens.

1. Phalenopsis amabilis Lindl. var. Aphrodite Ames Orcut-
DACE 2 : 226. This variety is regarded as a distinct species by
several authorities, but on characteristics which appear to me
negligible. For synonymy and varieties ORCHIDACE#, volume 2,
pages 224 to 229, should be studied. In Petiver’s Gazophyla-
cium, plate 103, fig. 10, this species is represented. Probably from
the Camelli specimens referred to in Ray’s Historia Plantarum.

9. Phalenopsis Micholitzii Rolfe in Gard. Chron. (1890) 2 :
197. See also Orch. Rev. 13 : 229. I have specimens of the origi-
nal flowers collected by Micholitz which have been compared
with the type and verified by Mr. Rolfe. This species is closely re-
lated to Phalenopsis Lueddemanniana Reichb. f. The labellum
in its form and calli is very much like the labellum of P. Lued-
demanniana, and differs chiefly from it in the hairs on the disc
being scattered and not gathered into a tuft. But even this dis-
tinction only holds in special cases. From C. A. Wenzel (054
Leyte) I have specimens which are very similar to P. Micholitzi,
although they match flowers of P. Lweddemanniana equally
well. Mr. Wenzel describes the flowers as odorless, green, brown,
white, yellow, and purple. Mr. Rolfe in the Orchid Review
(J. c.) compares P. Micholitzi to P. tetraspis Reichb. f., which
has white flowers. Unfortunately no technical description of
Mr. Rolfe’s species is known to me. The name occurs in Gar-
den Journals with brief characterizations. In the Orchid Review

[ 217 ]

79. AERIDES Lour.

Although numerous garden forms have been described from
Philippine specimens, the genus Aérides is represented by few
species in the Philippines. 4érides quinquevulnerum is by far the
most common species. From dried specimens it is extremely dif-
ficult to recognize many of the forms that are cultivated under
various names.

1. Aérides Augustianum Fo/fe in Lindenia 5 : 39, pl. 210; Gard.
Chron. (1890) 1 : 9. I have not seen any specimens of this among
the collections from the Bureau of Science. It has purplish flowers
and a very long spur on the labellum.

6. Aérides Roebelenii Reichb. f- in Gard. Chron. (1884) 1: 510

able to it from the Philippines.

7. Aérides Rohanianum Rerchb. f. in Gard. Chron. (1884) 1:
206, and A.suavissimum Lindl. Journ. Hort. Soc. 4: 264, belong
to A. odoratum Lour. Undoubtedly several species which are still
upheld will prove to be forms of this very variable and widely
distributed species.

8. Aérides Savageanum Veitch Man. 7:78.

80. RHYNCHOSTYLIS Bi.
Two species are natives of the Philippines. About three species
constitute the genus. The synonymy is copious.

1. Rhynchostylis retusa B/. Biydr. 286.

Luzon, PaLtawan.

2. Rhynchostylis violacea Feichb. f. in Bonpl. 2:93. Vanda
violacea Lindl. in Bot. Reg. (1841) Mise. p. 12; (1847) t. 30. The
flowers of this species are larger than in R#. retusa Bl. and possess
a distinctly retuse-apiculate labellum. Lindley’s description and
the accompanying plate in the Botanical Register of 1847 were
prepared from material introduced from the Philippine Islands.
Lindley reported that Cuming found the species in Manila and
introduced it to Europe. In the Botanical Magazine of 1864.
plate 5433 depicts a white-flowered species that is hardly differ-
ent from #. violacea. This species was described by Hooker under
the name Saccolabium Harrisonianum and separated specifically

[ 219 ]

ORCHIDACEA

from the species illustrated in the Botanical Register by slight
differences discoverable in the flower. Hooker’s species was im-
ported from ‘‘Puio Copang, in the Chinese seas.”

Luzon, W.S. Lyon 50, 1908. Referred by the collector to Aérides quin-
quevulnerum Lindl. with the following note: “But the wounds 2.e. spots
(now faded), are sometimes two or three instead of one on each perianth
segment.” In addition to the specimens collected by Lyon I possess a
number of plants, presumably discovered in Luzon by a native collector.
This appears to be the species figured by Petiver in his Gazophylacium
(plate 103, fig. 11) from Camelli’s plants gathered in Luzon and published
by Ray in Historia Plantarum.

81. LUISIA Gaudich.
Probably thirty species constitute the genus, of which four come
from the Philippine Islands. All of them are endemic with the
exception of Luisa teretifola, which is a native of Java, Am-
boina, New Caledonia, and Ceylon.

l. c. This species is unknown to me. ZL. teretifolia is well charac-
terized by linear-oblong, obtuse petals, which slightly exceed the
upper sepal in length. The labellum is panduriform, and con-
cave near the column. Reichenbach’s description of the petals of
LL. valida applies equally well to the petals of L. teretifolia; in

[ 220 ]

ORCHIDACE

fact, it applies only to L. teretifolia of all the species from the
Philippines that I have seen, and taken in conjunction with his
description of the labellum of ZL. vakda, arouses a strong suspi-
cion in my mind that L. teretifolia and L. valida are conspecific,
or that my conception of L. teretifolia is erroneous. From both
species L. Foxworth and L. Ramosi are clearly distinct, through
the broad petals, which in L. Foxworth are oblong-lanceolate
and in L. Ramos unequally ovate.

82. ARACHNIS Bi.

About fifteen species are referable to this genus. Only one species
has been discovered in the Philippines. Also represented by spe-
cies in Annam, Borneo, New Guinea, Java, and Celebes.

1. Arachnis Lyonu sp. nov. Radices elongate, vaginas perfo-

Allied to the Bornean Arachnis breviscapa J. J. Smith, but in
part distinguishable by its smaller flowers. The hinged or mov-
able labellum separates this species generically from Vandopsis

J. J. Smith is adopted.

Two species are known to be natives of the Philippines. It is also
represented in Burma, China, New Guinea, and the Liukiu
Archipelago.

Vandopsis leytensis is readily distinguishable from Vandopsis
Lissochiloides Pfitz. by the very different labellum and shorter
leaves. The labellum is concave at base and is divisible into hy-
pochile and epichile. The epichile is made up of the middle and
lateral lobes, the lateral lobes spreading at right angles, or nearly
so, to the middle lobe. The hypochile is densely pubescent along
themedian line. Directly in front of the hypochile the lateral lobes
are situated.

86. RENANTHERA Louwr.
As at present understood this is a small genus confined to the
tropics of the Old World. From Mindanao there is a specimen
in the Bureau of Science Herbarium, collected by Mary Strong
Clemens (773), which consists of the inflorescence only. It ap-
pears to be near #. matutina Lindl., but the lateral sepals are free.
1. Renanthera elongata Lindl. Gen. & Sp. Orch. 218. This
species, under the name RF. micrantha B1., is referred to the Phil-
ippines in Xenia Orchidacea (1:92). The R. micrantha of Xenia
is referred to &. elongata Lindl. by J. J. Smith. Plate 41 of the
Botanical Register (1843), which represents 2. elongata, accom-
panies a brief note by Lindley, who referred to specimens col-
lected by Cuming in the Philippines. I have not seen any mate-
rial of this species among the Bureau of Science collections.

This is a near ally of Renanthera angustifolia Hook. f. (Ic. Pl.
2138), but distinguishable from it by means of the differently
shaped perianth organs. The peduncle is unbranched. The gyno-
stemium is entire at the summit. The lateral sepals just below
the tip are provided with a hook-shaped process.

a variety of V’. tricolor, but as it is quite probable that there are
differences between V’. tricolor and V. luzonica that are conspic-
uous in living plants, the name V’. uzonica may represent a dis-
tinct species. The flowers are said to be nearly odorless, white,
with the labellum white at base and light purple above.

My specimens are from Mount Balacbac, Bulacan Province, Luzon,
Loher 6006.

89. SACCOLABIUM Bi.

As at present understood, Saccolabium is a small genus partly
distinguished from Sarcochilus by the absence of a foot on the
column. It is represented in Java, Celebes, New Guinea, ete.
Under Saccolabium numerous species have been reported from
the Philippines. Saccolabium bifidum Lindl. = Sarcanthus bifidus
Ames. §. Blumet Lindl. = Rhynchostyls retusa Bl. S. chionan-
thum Lindl. = Schenorchis micrantha Bl. S. compressum Lindl, =
Robiquetia compressa Schltr. S. miniatum Lindl. = Ascocentrum
mimatum Schitr.

The synonymy of Rhynchostyhs retusa in ORCHIDACES, vol-
ume 2, should be studied in this connection. Several species have
been referred to the Philippines under Saccolabium which are
unknown to me, or are not represented in the Bureau of Science
collection. These I have purposely omitted from my list, as they
are doubtful.

lobum medium protumidus, ceteroqui triangulus, complanatus
vel obconicus, usque ad apicem liberum fastigatus, circiter 5 mm.

The lateral lobes of the labellum are quadrate and apparently
composed of two members, the posterior member being adher-
ent to the outside of the anterior one and above produced into
a short obtuse or somewhat pointed lobe. The posterior mem-
ber when forced apart from the anterior one is narrowly trian-
gular in shape. The middle lobe of the labellum is very fleshy,
and is subtended by a fleshy projection of the sac. The sac itself is

[ 227 ]

ORCHIDACEA

triangular, probably flattened laterally in life, without dividing
membranes or raised veins on the inner walls. The labellum might
be described as three-lobed, with the middle lobe divided and the
divisions adherent to the lateral lobes. But this is hardly a cor-
rect description, as the structure of the labellum does not warrant
it. What I have termed the anterior member of each lateral pair
of lobes may be an extraordinarily developed lamina; that it is
so seems very probable, as the anterior margin of the posterior
member of each pair joins the middle lobe and together with it
ferms a continuous boundary within which the anterior mem-
ber of each pair of lateral lobes is contained, appearing like a
callus arising from the throat of the fleshy sac or spur.

That this species belongs to the genus Saccolabium seems very
probable, but in view of the differing opinions regarding generic
limitations in the group, future studies may prove that I have
not interpreted its characters properly. The flowers open, more
or less, at the same time on a thickened clavate rhachis.

From the description of Saccolabium sarcochiloides Schltr.
this species must be a near ally, but the flowers as shown by the
plate published by Schlechter are structurally dissimilar from
S. Hscritoru.

The specimens from Mount Mariveles collected by Dr. Cope-
land are smaller than the type, but exhibit the same peculiarities
in floral structure. The lateral lobes of the labellum are purple
and erect.

Saccolabium Loheri is a near ally of S. sarcochiloides Schltr.,

sembles, when seen laterally, a perfect shoe, the toe protruding
beneath the small middle lobe, and the heel being formed by an
indentation of the sac.

middle lobe the sac is slightly protuberant and the anterior wall
is very much thickened.

90. GASTROCHILUS Don.
The dismemberment of the genus Saccolabium necessitated the
reinstatement of Gastrochilus to receive those species which have
a labellum characterized by a hemispherical, wide-mouthed hy-
pochile and a flat, somewhat triangular, outspread epichile which
is more or less fringed at the margin and which gives to the la-
bellum the appearance of an inverted jockey cap. About sixteen
species are recognized from Ceylon, Sikkim-Himalaya, Burma,
India, Japan, Moulmein, and G. sororius Schltr. from Java. Sac-
colahium formosanum Hayata, which I only know from the ori-
ginal description and the figure in Icones Plantarum Formosana-
rum (4:88), is a native of Arisan, Formosa, with the epichile of
the labellum entire. (Cf. Schlechter’s Die Gattungen Gastrochi-

The type consists of a single specimen and is the only Philip-
pine representative of the genus Gastrochilus that has come to
my attention. It is a near ally of Gastrochilus calceolaris Don,
but the leaves are different from the leaves of that species and
the flowers are smaller than those of G. calceolaris. G. sororius
Schltr. is also a nearly related species, but with different leaves.
Although I have withheld this species from publication since
1904, in anticipation of additional material to clarify it, it re-
mains unique among the collections of the Bureau of Science.

Structurally the specimens on which my description is based
appear to belong to Omcea. From Omeea micrantha Bl. they differ
in the several flowered inflorescence. The floral structure, how-
ever, is very similar to that of Blume’s species. The general habit
of the plants suggests Microsaccus Wenzelu, but the leaves are
much narrower perpendicularly and not so crowded. I’rom dried
specimens the leaves appear to have been deeply sulcate both
above and beneath.

92, ASCOCENTRUM Schltr.
Dr. R. Schlechter has proposed the new genus Ascocentrum
to receive those species which are allied to the following spe-
cies formerly ascribed to Saccolabium: S. awrantiacum Schltr.,
S. curvifolium Lindl., S. ampulaceum Lindl., and S. miniatum
Lindl. Saccolabium as at present understood is closely related
to Sarcochilus, from which genus it is distinguished chiefly by
the footless column. In the Philippines Saccolabium is repre-
sented by S. confuswm Ames, S. luzonense Ames, S. sarcochiloides
Schltr., and SS. Vanoverberghi Ames.

I have examined several collections from Luzon which appear
to be referable to this species, but which are much taller, with
longer leaves and freer habit, than the type. It is not unlikely
that the plants found by Merrill on rocks in the open show a
more compact form of growth than plants which grow in the

forest on trees. The spur of the lip is without callosities, septa, or

The Philippine material which I have referred to Lindley’s
Saccolabium compressum agrees fairly well with that species in
the floral structure, although the vegetative parts are not so
robust as those shown in the plate published in Sertum Orchi-
daceum. In the Lindley Herbarium at the Royal Gardens, Kew,
there is a sketch of a flower which agrees very well with the
details of flowers from Philippine specimens which I have ex-
amined.

Dr. Schlechter has referred Saccolabium compressum to Robi-
quetia, in conformity with the present tendency to dismember
the genus Saccolabium. The sac is free from callosities.

Saccolabium densiflorum, Lindley wrote as follows: “Among

has made its appearance, having flowered with Messrs. Loddiges.
It has small, pale, dull brownish-yellow flowers of a very fleshy
consistence. The specimen that flowered was a small one. The

In general habit similar to Robiquetia spathulata J. J. Smith,
but very distinct in the construction of the labellum.

Robiquetia Vanoverberghi is a robust plant which is rather
well characterized among its near allies in the Philippines by the
branched inflorescence and candle-snuffer-shaped labellum. The
structure of the column is not unlike that of Robiquetia spathu-
lata, but in dried specimens it is often impossible to study the
finer details of structure, and errors in judgment are to be ex-
pected. There is no posterior callus in the sac.

In the Philippine Journal of Science (4: 675 (C) Bot.) I re-
ferred material collected in Luzon by Ramos (Bur. Sci. 3055)
to Saccolabium chionanthum Lindl. Recently, in a review of sev-
eral genera of the Sarcanthine, J. J. Smith assigned numerous
species, which had been retained in Saccolabium, to Lindley’s
genus Sarcanthus. In Blume’s genus Schoenorchis he placed sev-
eral species of Saccolabium that are partly characterized by linear
or terete leaves, among others Saccolabium chionanthum. The
synonymy proposed by Smith is given above.

To Schenorchis micrantha Bl. I refer the following Philip-
pine specimens which I have recently studied:

The structure of the gynostemium resembles that of Schanor-
chis paniculata Bl. The sac of the labellum is about 1 mm. wide
at the dilated tip; in general outline it is not unlike the sac of
Pomatocalpa spicatum Breda as represented in Ann. Bot. Gard.
Cale. 5: t. 84. The sepals are directed forward. The lateral lobes
of the labellum are erect, rounded, as high as the gynostemium,
and in front form an acute angle where they join the middle lobe.
The middle lobe appears to have been slightly conduplicate when
fresh. The type consists of a single plant. I have not seen any
other material.

At first glance this species bears a striking resemblance to
Schanorchis minimifiora (Hook. f.), from which it differs in the
excavated, not terete, middle lobe of the labellum. In comparing
the two species one might almost suppose that the details of the
labellum and rostellum were inaccurately interpreted as illus-
trated in Hooker’s Icones. Hooker’s figure does not show the
attachment of the lateral sepals to the sac of the labellum, nor
does it make clear that the petals are wider than the lateral
sepals. In S. philippinensis the middle lobe of the labellum is
deeply excavated so that the erect point resembles the lip of a
pitcher.

This is a compact, interesting little species, which produces
from two to three paniculate inflorescences from the axils of the
upper leaves. Fruiting and flowering panicles occur at the same
time, so that the flowering season is apparently a long one. The
lateral lobes of the labellum are distinguishable merely as the
rounded-up sides of the sac, and in some specimens pass im-
perceptibly into the fleshy middle lobe. Plants scarcely 12 cm.
tall from base of stem to tip of inflorescence have been noted
among the specimens that constitute the original collection of
this species. Schenorchis Vanoverberghit is nearly allied to S. pa-

niculata Bl.

‘Phe septum of the labellum on the posterior wall of the sac,
just above the middle, apparently divides to form a horizontal
quadrate plate of tissue; on the anterior wall of the sac the sep-
tum forms the dividing wall between two compartments which
in front rise as high as the middle of the sac. In habit similar to
Camarotis Manni King & Pantling, but with very different infio-
rescence and labellum. C. sterrophylla J. J. Smith from Celebes
is different from C. utriculosa in the details of the labellum.

97. SARCANTHUS Lindl.

The genus Sarcanthus, as now understood, includes those spe-
cies which bear onthe posterior wall of the spur, just below the col-
umn, a fleshy, variously formed callus, and on the anterior wall
either well-defined calli or conspicuous thickenings. The septum
in the labellum, which has usually served as a distinguishing
trait of Sarcanthus, may be obsolete.

and ovaries smooth, slender, up to 8 mm. long. Lateral sepals ob-
long, subfalcate, obtuse, 3 mm. long, up to 1.5 mm. wide. Upper
sepal elliptic-oblong, slightly concave, obtuse, 2.5 mm. long.
Petals oblong, at the apex attenuated, scarcely acute, about 2
mm. long, 1 mm. wide. Labellum calcarate, three-lobed, middle
lobe triangular at base with a jointed, fleshy, narrowly triangular,
setaceously bifid appendage. Lateral lobes linear, longer than the
gynostemium, erect, obtuse, about 2 mm. long, hardly .5 mm.
wide. Spur about 3 mm. long, near the mouth constricted, pro-
vided with a small fleshy callus on the posterior wall beneath
the column, the tip inflated. Gynostemium fleshy, in front at the
apex two-winged, the wings quadrate. Pollinia two.

In Paxton’s Magazine of Botany (6:262) Saccolabium bifi-
dum is referred to in a brief note. Its habit is said to resemble
that of some species of Notylia, “the manner in which the flowers
are produced, their structure, and exceeding minuteness, being
so far as a hasty glance can determine, in complete accord-
ance with the members of that genus.” Sarcanthus bifidus, of
course, has terete stems and is in structure extremely unlike
any Notylia species, but to one who knows the characteristics
of Notylia the above description in Paxton’s Magazine is worth
many words of technical description to call to mind the aspect
of S. bifidus.

The labellum is not unlike that of Sarcanthus javanicus J. J.
Smith, but the side lobes are oblong and equal the column in
length, and the column appears to be different. There is no sep-
tum in the spur. The affinities of this species are surely with Sar-
canthus, but the structure of the column is that of Robiquetia as
I understand that genus. Undoubtedly there will be much more
confusion in the group to which this species belongs before mat-
ters are simplified, but at the present timethe limits of such genera

so obscure that it is sometimes impossible to ascertain to which
one a given species may belong.

Allied with Sarcanthus subulatus Reichb. f. What appears to
be the same species comes from Palawan (C. M. Weber 602). In
the dried state the leaves of the specimens collected by Weber
are uniformly flat and lack the terete aspect which is possessed
by some of the dried specimens I have examined. In both series
of specimens the leaves are more or less subulate, and fragile,
near the tip. The sac of the lip is not unlike that of S. subulatus
Reichb. f. from Java.

A very characteristic representation of this species appeared
on plate 103, fig. 14, of Petiver’s Gazophylacium. This figure was
taken from one of the Camelli specimens described in the third
volume of Ray’s Historia Plantarum.

For a sketch of Lindley’s type at Kew I am indebted to Sir
David Prain. This sketch leaves no room for doubt regarding
the species Lindley described under Clezsostoma dealbatum in the
Botanical Register of 1843. A colored sketch of a single flower
shows the sepals and petals yellow stained with a brownish-red
color, and the labellum white, tinged with pale magenta on the
front.

Sarcanthus micranthus is related to S. paniculatus J. J. Smith,
and to S. racemifer Reichb. f. The habit of 8. micranthus is more
slender, however, and the smaller flowers are in fewer branched
panicles than in |S. racemifer.

The callus on the posterior wall of the sac is scale-like and
retuse rather than bilobed. The calli on the anterior wall near the
base of the middle lobe are fleshy and somewhat elongated. On
the middle of the lobe itself there are two folds of tissue which
are diagonally situated, and which converge, but do not unite, near
the tip of the middle lobe. The septum at the base of the sac is
very weakly developed. In several flowers examined the calli of

the sac were almost absent.

The laterally flattened callus on the posterior wall of the sac
of the labellum is situated just below the column and reaches
across the opening of the sac nearly to the base of the mid-lobe.
The calli on the anterior wall are decurrent on the lateral lobes,

and appear to be connected by a thickening of the tissues at the

believe that it belongs to Trichoglottis. Krinzlin cites Pomato-

choglottis ionosma J. J. Smith. Cletsostoma rosea Lindl. in Bot.

dense pubescens. Pollinia 4, in globulos 2 unita, inaequalia.

In habit somewhat similar to T72choglottis tonosma (Lindl.)
J.J.Smith. The type consists of a single specimen, which does not
show any tendency toward the production of an elongated stem.
The labellum suggests the labellum of 7°. pantherina J. J. Smith.
At the base of the bristly middle lobe is a slight depression of
the dise in which there is a small papilla-like callus, just as in
T. ionosma. The structure of the labellum and the larger flowers
serve to distinguish 7. /wzonensis from 7. zonosma, its nearest
ally in the Philippines. The loosely paniculate inflorescence is
generically interesting.

In my herbarium there is a specimen from Agusan Province,
Mindanao, collected by C. M. Weber (103), which I assume may
be conspecific with 7’. /wzonensis. It is a specimen in fruit, but

[ 256 ]

ORCHIDACE#

the remains of one flower show a labellum similar to that of
T’. luzonensis. Should my assumption prove correct, the descrip-
tion of the type would need modification, as Weber’s specimen
has an elongated stem with the leaves 2-3 cm. apart.

Microsaccus Wenzelii is closely related to M. brevifolius J. J.
Smith, from which it differs in habit and in the form of the
sepals and petals. Where the column unites with the labellum
in front there are two thickenings on the disc at the entrance to
the saccate spur. Microsaccus Wenzeli is the first species of its
genus recorded as a native of the Philippine Islands.

Habenaria Vanoverberghii, 15; H. Zephyrica, LG:

ADDENDUM

Vanda clitellaria Reichb. f. in Flora 55 : 277. Reichenbach de-
scribed this species from material collected by the Wilkes Expe-
dition. The source of the type is given as Mangs Islands. Mr.
Elmer D. Merrill writes that Mangs is a misprint for Mangsi
or Mangsee, small islands in the Sulu Sea not far from Balabac.
The locality from which V’. clitellaria was obtained is written
Mangsi on the original label that accompanies the Wilkes spe-
cimen preserved in the Gray Herbarium. V’. chtellaria is closely
allied to V. lamellata Lindl., and is perhaps only a form of it.
