CONTRIBUTIONS

TO THE
FLORA OF SIAM. tmeary
REY YORK
OTANICAL

DICOTYLEDONES. Gain

Since the time of publication in the Bull. Herb. Boiss. (1904-5)
by Dr. F. N. Williams of his “ Liste des plantes connues du Siam,”
our knowledge of the Flora of Siam has made great strides. The
penultimate part of the Flora of Koh Chang dealing with the
Palmae, Lentibularieae and the Lichenes has appeared. As men-
tioned in Kew Bull. 1911, p. 7, Dr. C. C. Hosseus visited Siam in
1904—5 and made large collections of plants. Since his return to
Europe he has published in various continental magazines a large
number of papers dealing with various subjects of scientific interest,
and a list of those papers—so far as known to the author—which
have a direct bearing on the present contribution will be given in an
addendum.

It might not be out of place to say a few words here on those
papers which the writer has found most useful when compiling the
present lists. Probably the most important are to be found in the
Beihefte zum Bot. Centralblatt— Beitriige zur Flora Siams” in
vol. xxvil., pp. 455-507 and ‘“ Die botanischen Ergebnisse meiner
Expedition nach Siam” in vol. xxviii., pp. 357-457. The former
gives lists of all the plants of certain families known from Siam, but
in the latter the author confines his attention to the plants collected
by himself and gives a list of nearly all the plants of his own
collection. In both papers the author expresses his indebted-
ness to various authorities who assisted him in determining the
plants. In Engler’s Bot. Jahrb., vol. xli., pp. 62-73, Dr. Hosseus
gives a list of all the Acanthaceae known from Siam. Most of his
plants in this family were determined by the late C. B. Clarke—a
recognised authority on Acanthaceae. In the same publication are
also to be found “ Beitriige zur Flora des Doi Sutiip” (vol. xl.,
pp. 92-99) and “ Beitriige zur Flora von Wang Djao am Mi Ping
in Mittel Siam ” (vol. xlv. , pp. 366-374)—two papers dealing with
the general aspects of the flora of the regions. Also in Engler’s
Bot. Jahrb., vol. xli., pp. 55-61, is a description, accompanied with
excellent fioures and a full discussion on its affinity with neighbour-
ing genera, of a very interesting new genus of Rafflesiaceae, called
by the author Richthofenia. Reference might be made here to
several other papers, but for these the reader must be referred to the
list at the end of the present paper.

The present contribution may be regarded as a reprint—with
additions—of the papers written by the author and published in
Kew Bull. 1911, pp. 7-60 and 385-474. As explained there, the
primary idea was to give additions to William’s list referred to

4

above, and for this purpose the same geographical region is treated
of as comprising Siam as in William’s list with the exception of
Siamese Malay Peninsula, which has been accounted for by Ridley
in his ** Flora of Lower Siam” published in Journ. Str. Br. Roy.
As. Soc., 59, pp. 15-234. <As before, all Dr. Kerr’s plants are
included, whether they had been recorded for Siam in William’s
list or not. The reason for this was to illustrate the more fully
Dr. Kerr’s paper in Kew Bull. 1911, pp. 1-6, dealing with the
vegetation of Doi Sootep—a paper which was anticipated by
Dr. Hosseus in his paper on Doi Sootep mentioned above.

The additional material accounted for here consists chiefly of the
continued collections forwarded by Dr. Kerr. One’s indebtedness
to Dr. Kerr for the magnificent specimens which he continues to
send home from a region which is still far from well known from a
botanical point of view can hardly be overestimated. Several small
consignments have also been received through the Conservator of
Forests, Bangkok, from the Phre district collected by Luang
Vanpruk. The plants dealt with in the present paper are those
received at Kew up to the end of 1911.

Throughout the list references have been given to Hooker’s Flora
of British India (contracted F.B.I.), to Kurz’s Forest Flora of
Burma (contracted For. Fl. Burma) and to Collett and Hemsley’s
paper on the Flora of the Shan States published in the Journal of
the Linnean Society. References have also been given to Lecomte’s
Flore Generale de VIndo-Chine so far as that work has been
published (contracted Fl. Indo-Chine) and to the two papers by
Hosseus quoted above—that in Beihefte zum Bot. Centralblatt,
vol, xxvil., being contracted Hosseus i., and that in the same publi-
cation, vol. xxviil., being contracted Hosseus ii. Various other
papers which serve in the writer’s opinion to throw light on the
species under consideration, 7.e., monographs, &c., have also been
referred to.

The distribution of the species is taken, except when otherwise
stated, from specimens in the Kew Herbarium. Several species are
quoted, of which no specimens from Siam have been seen, but in
such cases the authority for the record is alone quoted.

The sequence of Bentham and Hooker’s Genera Plantarum is
followed on the whole and the species are arranged alphabetically
under the genera.

1207 ; in deciduous jungle, 330 m., Kerr, 1848. [In the latter col-
‘lection the carpels are generally 3 in number. ]

According to Kerr the fruit is edible.

Lao name, Noom Wooa (ex Kerr).

The systematic position of this plant is a little doubtful. It
agrees with Unona in everything but the carpels and would appear
to be intermediate between that genus with its many carpels and
Monocarpia with its solitary carpel.

Hosseus, ii. p. 413, determines this plant as Thea japonica, Linn.,
forma. In Kew Bull. 1911, p. 16, the writer referred it to
C. drupifera, Lour. After further examination of the specimens
quoted and a comparison with the material in Herb. Kew the writer
has failed to match it absolutely with any specimen in the
Herbarium, and considering the rather involved state of the
synonymy within the genus, he prefers to leave the identification

doubtful.

A portion of Kerr’s 1067 was sent to Calcutta Herbarium, and
was compared with the material there by Mr. W. W. Smith, who
remarks that it agrees well with the Burmese specimens referred to
D. costatus by the late Sir George King. Through lack of
material, Dyer, in the Flora of British India, l.c., reduced this
species to D. alatus, and Brandis, for the same reason, while
enumerating it as a distinct species, seems to indicate that it is not
a very satisfactory species. The receipt of good material shows,
however, that it is a well-marked species, and quite distinct from
D. alatus.

Ryan and Kerr, in their paper on the Dipterocarpaceae of
Northern Siam in Journal Siam Soc., vol. vii., describe D. obtusi-
folius as having “the young shoots, petioles, stipules and inflore-
scence densely clothed with long tawny fascicled hairs,” and
describe a variety subnudus which has the young shoots and
stipules quite glabrous, the petiole glabrous for the greater part of
its length, and the calyx tube quite glabrous or silky pubescent.

Hosseus, ii. p. 413, refers his 298 to D. Duperreanus, Pierre and
says that that species is very closely allied to D. obtusifolius. So
far as the material in Herb. Kew goes, it appears advisable to the
writer to follow the first-named authors and regard the one plant as
‘a variety of the other. The two plants apparently bear exactly
the same relationship to each other as Pentacme siamensis does to
its variety mekongensis.

Here again there are two varieties bearing the same relationship

Ryan and Kerr l.c., p. 4. Large suites of specimens have been
received lately at Kew from Dr. Kerr and to the writer these bear
out the advisability of following the treatment proposed by Ryan
and Kerr,

this species, and which may eventually have to be described as a

In identifying the plants belonging to this critical genus I have
availed myself of the able assistance of Mr. J. R. Drummond who
has spent much time in the study of this group. The present state
of our knowledge of the Indo-Chinese species and the complicated
synonymy of the Indian species have forbidden the giving as full
references to published works as have been given throughout the
rest of this paper.

Chiengmai, mixed jungle on Doi Sootep, 450-540 m., Kerr, 895,

At first sight the variety is markedly different from the type in
the total or almost total suppression of the rather long stiffish hairs
on the branchlets and panicles. The type is represented by
Clarke’s fruiting Chittagong specimens only and the fruit except
for the rather stiffer hairs on the umbo is very similar to that of the
Siam plant.

Mons. Gagnepain, who was recently engaged in a study of the
species of Vrtis and allied genera and who has kindly collaborated
with me in the description of this species, has supplied very copious
notes on two allies of this plant.

T. cruciatum differs from 7. rupestre, Planch., in (1) its petiolules
being equal and its leaflets more symmetric at the base ; (2) its
sessile inflorescence ; (3) its corolla not all papillose ; (4) its large
Maltese cross-shaped stigma ; and (5) its small acute calyx teeth.

From 7. glabratum, Planch., it is distinguished by (1) its larger
leaflets with equal petiolules; (2) its more condensed and much
narrower inflorescence ; (3) its shorter flower buds ; (4) its corni-
culate petals ; (5) its large sessile stigma; and (6) its short acute
(not truncate) calyx teeth.

Mons. Gagnepain further remarks that 7. cruciatum possesses
the largest stigma of the species examined by him.

The writer is deeply indebted to Prof. Radlkofer for kindly
naming most of the additional Siamese material, In addition to

AT

describing the two new species of Sapindaceae and one of Simaru-
baceae he has kindly supplied the writer with the names of three
Siamese plants mentioned in Cat. Hort. Bogor. 1866, pp. 391-2 :—
Capura sp., Phoon rieng soeiin is Otophora fruticosa, Blume.
Harpullia sp. is Arfeutllea arborescens, Pierre.
Mahoeat 73 is Erioglossum rubiginosum, Blume.
A very doubtful record for Siam and one which must probably
be deleted from the area treated in this paper is Arytera montana
recorded by Williams for Lower Siam.

The plant collected by Schmidt is probably correctly referred to
D. umbellatum which, as already pointed out by Prain (Journ. As.

collected at Wang Djao by Lindhard has almost certainly been
wrongly determined as D. umbellatum.

a not uncommon occurrence in this section of the Phaseoleae. There
is no trace on the herbarium sheet of the name Pueraria phaseoloides,
which, according to Williams, l.c., had been erroneously given to
this plant, but in any case the name he suggests is equally
inapplicable.

This plant which was referred doubtfully to D. falcatus by the
writer proves on further examination to be quite distinct from that
species. It is equally distinct from D. biflorus. Its nearest ally is
Dolichos tenuicaulis (Phaseolus tenuicaulis, Baker) which is repre-
sented in Herb. Kew by Lace, 4270 and Robertson, 14 both from

67

Upper Burma. From D. tenuicaulis it is however quite distinct
and it may prove to be a new species but the writer has not yet had
the opportunity to investigate it fully.

The authorship of this combination is usually credited to Wight

Wallich’s plant was a Mezoneuron they did not make the combina-
tion. The species is very poorly represented in Herb. Kew and it
is not without some hesitation that Kerr’s plant is referred to it.

Chiengmai, Doi Sootep, 720-1500 m., Hosseus, 478, Kerr, 1729.

To this species probably belongs Griffith's Prome Hill specimen
(Kew Distr., 1909) mentioned in Flora of British India, vol. ii.
p- 267 by Mr. Baker as a variety of C. javanica or a new species.

In his first paper Hosseus enumerates this plant as Cassia nodosa
and in his second maintains C. Bakeriana but in a footnote remarks
that he is doubtful if it can be retained as a good species. In the
writer’s opinion it is readily distinguished from C. nodosa by the
size of the flowers. Of true C. javanica there are in Herb. Kew
only two apparently wild specimens, both collected in Java and
these agree exactly with various cultivated specimens, e.g. those
issued under that name from the Calcutta Gardens. The Philippine
plant which commonly passes under the name of C. javanica is quite
distinct from that species in several points, the more evident of
which are the indumentum and colour of the branchlets, the shape
and size of the stipules, the shape and indumentum of the leaflets
and the shape of the petals and bracts. After a careful examination
of the material in Herb. Kew the writer is convinced that so far as
that material goes C. javanica is confined to Java.

Hosseus l.c. refers his 471 to B. variegata and his 407 to “ B.
variegata, Linn. vel sp.” 407 is not quite typical B. variegata but
the material in Herb. Kew is rather poor.

Ina footnote toi. p. 392 Hosseus explains that his determinations
of B. purpurea and B. variegata had by an oversight become reversed
in his first paper so the present writer has given no references to
that paper for the species in question.

Since the above description was drawn up the writer has dis-
covered that the plant described is Pahudia xylocarpa, Kurz. After
a careful examination of the material in Herb. Kew the writer is
convinced that Pahudia and Afzelia should be merged into one
genus as already suggested by Prain and Pahudia javanica be
named Afzelia javanica.

The plant above described should be named Afzelia xylocarpa,
Craib, comb. nov. with Pahudia xylocarpa, Kurz and Afzelia
stamica, Craib, as synonyms.

For uniformity with the Flora of British India the Siam plant
might have been treated as a variety of H. javanica but in the
writer’s opinion the variety Hookeri, C. B. Clarke, of H. javanica
should be raised to specific rank as should also the variety chinensis,
Dunn, of the same species. These three species H. chinensis,
H. Hookeri,and H. siamica, form a very natural group distinguished
from H, javanica by their solitary generally long peduncled umbels.

Wangerin, in his monograph of the <Alangiaceae in Engler’s
Pflanzenreich, quotes Kurz, For. Fl. Burma, for the true Marlea
tomentosa, Endl. The description given by Kurz does not, how-
ever, agree with the Java specimens, e.g., in the size of the flower and
in the indumentum of the under surface of the leaf. On the other
hand, Kurz’s description applies very well to the plant quoted
above, which is, in the writer’s opinion, the M. tomentosa, Kurz non
Endl. It may be noted that no Burmese specimen is quoted as
having been seen by Wangerin.

deciduous jungle on Doi Sootep 300-720 m. which he describes as
having prostrate creeping shoots. The latter would appear to have
grown under more adverse conditions and has slightly narrower
leaves which dry brown.

leaves being rounded not cuneate at the base and the serrations
being much finer. Hosseus regards his 335 and 397 as specifically

Kerr’s specimens differ from typical A. microlobus in the peduncle
being rather thicker, the flowers evidently slightly larger, calyx
lobes and corolla tube broader, and the fruit longer and narrower.
Unfortunately the material on which Pierre founded his species is
rather poor and in the absence of better material I hesitate to
separate the Chiengmai plant from it.

the case of the shape of the corona lobes.

A living plant sent by Dr. Kerr to the Trinity College Botanic
Gardens, Dublin, which flowered there in August of the present
year, differs from the wild specimens only in having a minute and
scanty pubescence on the stem, peduncle and both sides of the leaf
which may be due to change of climatic conditions.

Chiengmai, Doi Sootep, in mixed jungle, 550 m., Kerr, 1436, in

Of the above collections 1436 is typical A. tenuiflora, while 1338
and probably 2212 belong to the variety Parishii (T. And., pro sp.).

The writer has found it inexpedient at the present time to name
these plants critically since he has not seen all the plants described
as new species by C. B. Clarke under Leptostachya. A duplicate
of one of these is in Kew herbarium and it is certainly an Andro-
graphis. The writer had hoped to see these plants by this time and
drew Hosseus’ attention to the plant in Kew, but in his second paper,
at page 441, he repeats C. B. Clarke’s determinations.

In the length of the calyx teeth these specimens are intermediate
between the type and var. azurea, C. B. Clarke.

Hosseus ii. p. 429 refers his 370 to C. azurea, Wall., forma. He
also refers other collections which the writer has not seen to
C. azurea, Wall. and to C. tomentosa, Roxb. After further exami-
nation of the material in the herbarium the writer is forced to the
conclusion that these two are but forms of one species.

Chiengmai, Doi Sootep, 1600 m., Hosseus, 505.

As noted in Hook. Ic. Pl., le. Pax did not feel justified in
retaining Hemsley’s genus Phyllanthodendron and followed Mueller
in treating Schomburgk’s plant as a Phyllanthus. But there is
nothing to separate generically the plant collected by Hosseus and
made the type of the new genus Uranthera by Pax and
Hoffmann from Schomburgk’s plant. In floral detail Hosseus
505 agrees with the type of Phyllanthodendron roseum except that
the ovary is glabrous. The petaloid disk glands have been
regarded by Pax and Hoffmann as true petals and they have
therefore placed the plant in the tribe Cluytieae.

Hosseus, 11. p. 406, enumerates this plant as P. roseum, var. glabrum,
Craib. I had intended using that name until Dr. Hosseus drew my
attention to the publication of Uranthera siamensis. For the sake
of uniformity I then adopted the varietal name siamensis although
it was not an ideal name to use for a genus which at that time was
known only from Siam.

The plant described above is probably more nearly related to
A, Bunius, Spreng. than to A. cuspidatum, Muell.-Arg. From the
former it differs in its Jarger leaves and by the ovary which in
A, Bunius is long exserted but in A. Colletti? is included in the
calyx to about the middle. A. Bunius and A. Collettii have very
similar male flowers and inflorescences.

leaves lobed. The specimen collected by Anderson which agrees
exactly with those collected by Kerr shows no trace of lobing in
the leaves and is named M. membranacea in Kurz’s own hand-
writing, The specimens collected by Anderson, although not

him in his description at least so far as the simple leaves are
