(ORCHIDACEAE — MONANDRAE — COELOGYNINAE
— DENDROCHILUM)

HE publication of Orchidacez —-Monandre-Celogynine in Eng-

ler’s Das Pflanzenreich on November 26, 1907, necessitates exten-
sive alterations in my treatment of the Philippine species of the genus
Dendrochilum, on pages 11-12 and 76-122 of this volume. These altera-
tions, fortunately, are confined to a readjustment of authority for nomen-
elatorial combinations, and are indicated below as it is now too late, owing
to the nearness to completion of the press-work of this fascicle of Orchida-
cez, to make the corrections in their proper place.

As a review of the literature devoted to the genus Dendrochilum will
clearly show, there has been much uncertainty as to the generic worth of
three of the large groups which now compose it ; namely, Eudendrochilum,
Platyclinis, and Acoridium. These groups have been variously interpreted
by systematists, until at the present time there seems to be perfect agree-
ment as to their disposition as well-defined sections or subgenera of the
genus Dendrochilum. When in the Proceedings of the Biological Society
of Washington! (1906) I described eighteen new Philippine species under
the genus Acoridium, I was quite convinced that Acoridium was distinct
from Dendrochilum; later, however, as material for a more exhaustive
study came to me from the Philippines, I concluded that Acoridium must
be reduced to a section under Dendrochilum. I indicated my conclusions
to this effect in a paper entitled Orchidacee Halconenses, which appeared
last July in the Philippine Journal of Science,” and distributed the species
therein considered among three sections; namely, Eudendrochilum, Aco-
ridium and Platyclinis.

Early in February, 1907, I received from Dr. A. Engler, editor of Das
Pflanzenreich, a request for the loan of the types of my new species of
Acoridium, in order that they might be studied and included in Dr. E.

vi INTRODUCTION

Pfitzer’s monograph of the Celogyninz. It was not possible for me to
comply with this request, but, as engravings of the eighteen new species
of Dendrochilum published under Acoridium in the Proceedings of the
Biological Society of Washington were being made in Paris for fascicle
2 of Orchidacee, I arranged for a set of these to be sent to Dr. Engler.
The last thought in my mind when [I did this was that my confidence
would be abused, and that parts of my plates would be surreptitiously
converted into illustrations for Das Pflanzenreich before I myself had
seen the engraver’s final proofs.

If permission for the use of the plates had been requested, opportunity
would have been given for a friendly codperation which would have saved
Dr. Pfitzer’s monograph from unfortunate errors in citation, and would
have eliminated the disagreeable necessity on my part of explaining away
inconsistencies in the present work, over which I have had no control.

In every case where fascicle 2 of Orchidaceze (ined.) is cited in Dr.
Pfitzer’s monograph, Acoridium and not Dendrochilum is given as my con-
ception of the generic rank of my species. As the paper entitled Orchi-
dace Halconenses (which was prepared early in 1907) clearly shows, I
no longer adhere to my former views of Acoridium, but agree with J. J.
Smith! in regarding Acoridium, Platyclinis and Dendrochilum as conge-
neric. This was also clearly expressed under Dendrochilum on pages 12
and 77 of the present volume, when they were prepared for the press in
January, 1907.

Dr. Pfitzer’s death, which occurred in December, 1906, led to the
selection of Dr. Fritz Krinzlin to complete the work on the Ceelogyninze
for Das Pflanzenreich ; consequently Dr. Kranzlin is responsible for the
unfortunate complications which have arisen through the unwarranted
liberty taken with my plates and for the total disregard of my views
of the eighteen species which the plates represent. Notwithstanding
the fact that the titles on the plates are given under Dendrochilum, Dr.
Krinzlin has referred to them under Acoridium, and has neglected en-
tirely my paper on the orchids of Mt. Haleon. Here, however, it is
well to give Dr. Kranzlin the benefit of any doubt, in so far as the plates
submitted to him by the engraver were not sent to me for verification.

Before I pass from a consideration of the use made of my plates, it is
necessary that several misleading errors into which Dr. Kranzlin has
fallen regarding them should be cleared away. Fig. 38 of the Coelogy-

1 Notwithstanding J. J. Smith’s monograph of Dendrochilum in Recueil des Travaux Bot.
Neerl. no. 1 (1904), the fact is overlooked by Pfitzer & Krinzlin that in that monograph the

combinations D. corrugatum, D. Kingii, D. rufum (‘‘ rufa”) and D. grandiflorum are made for
the first time.

INTRODUCTION Vii

nine is made up from four of my plates of Dendrochilum species, from
which Dr. Kranzlin has selected all the lips and two plants in full. One
of the plants, designated by the letter Q, is said to represent my concep-
tion of D. tenuifolium. This is an error, as the plant in question is taken
from my illustration of D. graminifolium. Fig. 387 of the Celogynine is
borrowed without permission from fascicle 1 of Orchidacez. Although
considerably altered through redrawing, no mention of this fact is made.
In the legend that accompanies this figure, the letters J and K are said to
indicate the columns of D. sphacelatum and D. tenellum. Unfortunately
this isa most confusing blunder, as in culling out the analytical drawings
from my plates, side views of the /ips have been selected to represent
columns in the figure!

In the “ Conspectus subgenerum generis Dendrochili” on page 87, five
subgenera are admitted by Drs. Pfitzer and Kranzlin. I call attention
to this Conspectus, as the hasty inclusion in the Celogynine by Dr.
Kranzlin of the species illustrated by my plates numbered 21, 22 and 23
has brought about a state of things well nigh chaotic. In order to make
this statement clear, I here include a copy of the Conspectus.

The subgenus Acoridium as it is defined appears to have been originally
intended to include D. tenellwm,! the type of the group, and probably
D. sphacelatum. This fact must have been overlooked by Dr. Kranzlin
when D. turpe, which has minute lateral lip-lobes, D. ocellatum, the lip
of which is entire, D. oliganthum, in which the lateral lip-lobes are want-
ing, and D. Merrillii, in which the lateral lobes are much reduced (all
species studied by means of my plates), are admitted to the subgenus
Acoridium as defined in the Conspectus. It also becomes apparent that
the subgenus Aphanostelidion is seriously modified by a consideration of

1 On page 16 (Celogynine) Dr. Krinzlin refers to D. junceum Reichb. (a plant conspecific
with D. tenellum) as known only through Reichenbach’s description in Otia botanica Ham-
burgensia. Fortunately this is not so, as a duplicate type is to be found in the Gray Herbarium
and another specimen in the U. S. National Herbarium.

vill INTRODUCTION

the species just named, inasmuch as it should include them, or be redefined
or abandoned. Based, as it now is, on rudimentary column arms or their
absence, it merges with the subgenus Acoridium, which is characterized
by the total absence of the column arms, a condition quite overlooked
in the Conspectus. If it is redefined so as to include only those species
with rudimentary column arms such as D. Kingii, then D. Merrillii, which
is most readily distinguished from D. Kingii by the absence of column
arms, is widely out of place in its present position at the end of the sub-
genus Acoridium, where Dr. Krinzlin has placed it. In my disposition
of D. Merrillit I preferred to keep it among the true Acoridiums, yet
recognizing its affinity with the species of the subgenus Platyclinis by
bringing it in juxtaposition with them. Dr. Kranzlin has not seen fit to
depart far from the order of the species which I adopted under Acori-
dium proper in my paper published in the Proceedings of the Biological
Society of Washington, although in preparing a key to them he has
altered the position of several. By this blind adherence to my arrange-
ment without due regard to the raison d’étre of the order of the species
in the remainder of his paper he has missed the spirit of my classification
without improving that of his own; consequently he has removed D. Mer-
rillii as far as possible from D. Aingii. Furthermore it is well to note
that Dr. Kranzlin does not pretend to conform to the requirements of the
Conspectus, as his new species D. tenuissimum, characterized as being
without column arms, is placed in the subgenus Platyclinis.?

To those who may look to the Pfitzer-Kranzlin monograph of the
Celogyninz for a complete review of the species of Dendrochilum pub-
lished up to the early part of 1907, disappointment must result. The
oversight of Dr. Schlechter’s new species may be attributable to inor-
dinate haste in the preparation of the work, although that explanation
of their absence from it will scarcely be satisfactory when it is realized
that these appeared in such a prominent serial as the Bulletin Herbier
Boissier, ser. 2, vol. 6 (1906).

1 In this Key under C the contrasting characterizations ‘‘ Pedunculi infra inflorescentias
nudi” and “ Pedunculi infra inflorescentiam bracteis paleaceis imbricantibus vestiti”’ are abso-
lutely unwarranted by the material on which they are based, and must ever prove perplexing
and misleading. It is to these inadequate distinguishing characterizations that Dr. Kranzlin’s
departure from the order of species adopted in the paper referred to is due, and not to an
attempt to harmonize my material with the views expressed by the Conspectus.

2 D. cinnabarinum Pfitzer, a new Philippine species from Benguet, Luzon, which is also
found among the species of the subgenus Platyclinis properly belongs in subgenus Acoridium,
where it should be placed near D. affine. It is destitute of stelidia, and furthermore is inae-
curately described by Dr. Pfitzer as to its labellum, which is 3-lobed, with the middle lobe
hastate, acute, bicallose at base, 2 mm. long, and with the lateral lobes 1 mm. long, oblong-
obtuse. The figure in Das Pflanzenreich does not show the lateral lobes.

INTRODUCTION ix

Under Addenda and Corrigenda on page 162, Dr. Krinzlin places
among the doubtful or insufficiently known species Acoridiwm Whit-
fordii Rolfe.1 This species was clearly defined in the original descrip-
tion from material which, deposited in the Kew Herbarium, was not
beyond Dr. Krianzlin’s reach. Dr. Kranzlin’s objection to Mr. Rolfe’s
reference to D. pumilum Reichb. f. as a near affinity is scarcely a valid
excuse for placing it among the little known or obscure species of the
genus. Even though there may be doubt as to the plant described by
Reichenbach as Dendrochilum pumilum, it yet remains for some one to
prove that Cuming’s plant numbered 2102 from the Philippine Islands,
on which the description of D. pumilum was based, and of which number
there is a duplicate in the British Museum herbarium,” was a mixture.

When codperation and friendly correspondence are neglected by
workers in the same fields of systematic botany, confusion is the almost
inevitable result. On the other hand, it is quite improbable that codp-
eration will long continue when one worker appropriates the property
of his fellows and neglects the laws of courtesy.

long, 10-13 mm. wide. Flowers at the summit of the pseudobulbs,
mostly in pairs, apparently sessile between the leaves. Lateral
sepals oblong-lanceolate, acuminate, 5 mm. long, 2 mm. wide.
Upper sepal equal and similar to the laterals. Petals linear, acute,
5 mm. long,+1 mm. wide. Column adnate to the lip. Ovary
winged. Fruit an ellipsoidal, trialate capsule.

This interesting species — originally collected by Brogniart in
the island of Santa Catharina and described as a Celogyne —
was found in the United States first by Mr. A. A. Eaton, who
collected specimens in March, 1905, ten miles northeast of Ever-
glade, in Lee County, Florida. Mr. Eaton found the plants grow-

ing on pop-ash and spreading luxuriantly by means of the creep-
ing, elongated, ramifying rhizome. The plants appear to produce
cleistogamous flowers. Sepals and petals are greenish, the label-
lum white with a purplish spot at the base of the apiculate tip.

ILLUSTRATIONS OF THE GENUS
DENDROCHILUM

TE genus Dendrochilum as at present understood through
the recent monograph by J. J. Smith includes the genera Platy-
clinis founded by Bentham on Blume’s second section of Den-
drochilum, and Acoridium based on an imperfectly known plant
which Nees & Meyen referred to the Philydracee. Platyclinis
was characterized by the terminal, Dendrochilum by the lateral
origin of the inflorescence. Until recently Acoridium has been
interpreted through two or three species, all of which have been
also variously treated as Dendrochilum or Platyclinis, although
clearly marked by having the inflorescence terminal and the column
wingless. The species of characteristic Dendrochilum, that is,
plants with lateral flower shoots, are at present in the minority,
while the species assigned by authors to Platyclinis and Acoridium
form the bulk of the genus. This fact probably indicates that the
lateral inflorescence is anomalous in Dendrochilum, as it is in some
other genera; as, for example, in Epidendrum, where /. Stamfor-
dianum is exceptional in this respect.

Since the explorations of the Philippine Islands were under-
taken by the American Government, many additions have been
made to the genus which are of great importance in view of its
heretofore unsettled condition. These additions have been for the
most part of the nature of Acoridium, agreeing with A. tenel-
lum, Nees & Meyen, in the structure of the column, which is
devoid of lateral arms, or wings. Altogether they form a fairly
complete transition between A. tenellum and Dendrochilum
palawanense, and prove conclusively, it seems to me, that Acori-
dium should include Bentham’s Platyclinis. Furthermore, they
clearly show that the generic limits may properly be widened to
include not only such habitally very dissimilar forms as A. tenel-
lum and P. Cobbiana, but also D. aurantiacum and its allies.

12 ORCHIDACEZ

The column of typical Platyclinis has been relied on to a large
extent in the determination of species. The column is variously
winged, with the wings usually strongly developed, arising basally,
or from the middle, or from the summit. In such forms as Den-
drochilum palawanense and D. rufum J. J. Smith, however, the
wings are reduced to mere teeth; therefore the column in these
species begins to approach the form characteristic of Acoridium
as represented by D. Merrill. The column of typical Dendro-
chilum species has arms or wings as in Platyclinis; and no ge-
neric differences of any kind can be discerned in the flower. The
only considerable difference is in the origin of the inflorescence,
as before stated ; but I agree with J. J. Smith in denying generic
worth to this feature. The passage from one condition to the
other is so easy, that the position of the flower shoot must not be
relied on too much. Dendrochilum receives Platyclinis and conse-
quently Acoridium.

I have lately published several new species in this genus (Proc.
Biol. Soc. Wash. 19: 143, 1906). The names first given must
now be changed. Acoridium Williamsu, A. graminifolium, A.
tenuifolium, A. tenue, A. parvulum, A. venustulum, A. stricti-
forme, A. anfractum, A. recurvum, A. philippinense, A. turpe,

“S, foliis radicalibus . . . , spica laxa secunda multiflora pilosa,
bracteis lanceolatis acuminatis glabris floribus brevioribus, labello
ovato-lanceolato acuminato apice retrorsum lacero carnoso: callis
conicis.”’ — Lindley, loc. cit.

Plants 3.5-5 dm. tall, slender, flexuose. Roots fleshy, clustered,
numerous. Leaves fugaceous, linear, acute, + 1 dm. long, + 5mm.
wide, passing above into persistent foliose bracts which closely
sheath the stem. Scape sparsely pubescent above the uppermost
bract. Inflorescence + 1 dm. long, a secund, spicate raceme of
white tubular flowers. Floral bracts lanceolate, acute, smooth
or very sparsely pubescent, + 1 cm. long. Flowers + 8 mm. long.
Lateral sepals linear-oblong, 8 mm. long. Upper sepal similar to
the laterals, slightly larger. Petals linear-oblong, broadest above
the middle, + 8 mm. long. Labellum yellowish, narrowly oblong
or ovate-oblong, obtuse, somewhat dentate or crenate toward the
apex. Callosities smooth, conical. Column generically typical.

S. longilabris Lindl. was originally described from Louisiana
plants collected by Drummond. In Lindley’s herbarium at Kew
the type consists of a single specimen. In the Hookerian herba-
rium Drummond’s plant numbered 495, collected at “New Or-
leans ” in 1833, appears to be of the same collection as the plant
in Lindley’s herbarium. Drummond’s Texan specimens determined
by Lindley as S. longilabris belong to another species. Since

16 ORCHIDACEL

the publication of Lindley’s Genera and Species of Orchidaceous
Plants, Spiranthes longilabris has appeared in floras under the
names of Spiranthes brevifolia Chapm. and Gyrostachys brevi-
folia Kuntze.

This species has been found in the states of Florida, Mississippi,
and Texas. For more detailed record of distribution, the reader
is referred to ORcuIDACE# fascicle 1, p. 132 (1905).

STUDIES IN THE ORCHID FLORA OF THE
PHILIPPINES

THE greater part of the species listed in the following paper
were collected for the Bureau of Science of Manila. The mate-
rial from which the descriptions were drawn has been in most
eases carefully worked over in the herbaria of the Royal Gar-
dens at Kew and of the British Museum of Natural History, or
compared with the types of Blume’s Javan orchids preserved at
Leiden.

The specimens distributed by H. Cuming, with which I have
made comparisons, are indicated by the numbers published in
Vidal’s Phanerogame Cumingiane Philippinarum. My know-
ledge of Cuming’s plants is derived from the specimens deposited
in the herbaria of Kew and of the British Museum. I have also
made note of the orchids deposited in the Gray Herbarium at
Cambridge, collected in the Philippine Islands by the Wilkes
Expedition, which Reichenbach described and published in Otia
botanica Hamburgensis. Through the kindness of Dr. N. L. Brit-
ton, it has been possible to include the orchids preserved at the
New York Botanical Garden which R. 8. Williams collected durmg
his botanical explorations of the Philippines. In addition to the
above-mentioned sources I have drawn on my own herbarium for
species which might lend value to the paper.

The figures of flowers and analytical drawings were, without
exception, constructed with the aid of the camera-lucida. These
have been prepared from dried material, and therefore, while accu-
rate in outline, they do not always exhibit the attitudes of the parts
characteristic of the living flower. Each species described as new
is figured, in order that with greater surety it may be referred to
its proper place in synonymy should errors have been committed
through inadequacy of material or oversight. No attempt is made

18 ORCHIDACEHZ

to note the amount of reduction or enlargement of the figures, as
the magnitude of the parts is given in the descriptive text.

The species comprised in my first list of Philippine orchids,
published in fascicle 1 of OrcHipDacEs&, are not included in this
one, unless additional notes concerning them have been deemed
necessary, or new collections made which throw light on distribu-
tion and habitat.

As several changes in the names of species occur, necessitated
by the adoption of the nomenclatorial rules established by the
recent Vienna Botanical Congress, a more exhaustive bibliogra-
phy is here attempted than in the first list, in order that the liter-
ary history of each species may be studied and the results of the
application of priority rules followed. Biblographical references
that throw no light on the species and add nothing important to
the history of the subject are omitted as needlessly cumbersome.
In addition to the distribution of species in the Philippines, the
occurrence in other countries is noted of those species which are
not endemic. When authentic specimens have not been seen
from the extra-limital territories cited, reliance is placed on the
works of other authors in giving the distribution of species out-
side the Philippines.

In the case of new species here described, the type, unless
otherwise specified, is understood to be the first specimen cited,
and is deposited in the herbarium of the Bureau of Science at
Manila. Cotypes are usually to be found in my herbarium.

HABENARIA BISETA

This species is allied to H. aristata, Hook. f., from which it is
at once distinguishable by the much longer lateral divisions of the
lip and by the very different leaf arrangement. It is also closely
allied to 7. tipulifera Par. & Reichb. f., which has the leaves near
the middle of the stem. My material may prove to be merely
a form of H. tuberculata Reichb. f. Just behind the point where
the lateral filiform divisions arise, the labellum is provided with

ORCHIDACEA 31

a peculiar retrorse appendage, or lip, which hangs over the claw
near the aperture of the short spur.

Hooker in the Flora of British India places H. pelorioides among
the imperfectly known species, and describes it as an anomalous
plant of which he has seen only one indifferent specimen. The
present species is figured in connection with the original descrip-
tion by Reichenbach. According to the field notes accompanying
a specimen collected by R. Meyer, the tubers are edible.

In Orcuipace# fase. 1, 64, this species was called Habenaria
muricata Vidal. As this binomial is precluded by the H. muri-
cata of B. Rodriguez, who applied it to a South American species,
the name H. hystrix is here proposed for the Philippine plant.
M. Cogniaux in Martius’s Flora Brasiliensis gave the name ZH.

Rodriguesii to the Rodriguez plant to avoid future confusion,
but it seems that H. muricata of Vidal, notwithstanding the fact
that the specific name was given by Schauer in 1848 under Dis-
sorhynchium, is a homonym and cannot here be used.

yet approach it so closely that I have designated the Philippine

Through the middle of the labellum runs a raised nerve, or slightly
elevated keel; otherwise there are no crests or emergences, and
the dise is smooth.

The single specimen on which my determination is based has
been compared with the numerous forms in the Herbarium at
Kew. It appears to be a depauperate form of the species, agree-
ing with authentic material in floral conformation. The Merrill
plant has several very small leaves. Should there prove to be a

A. benguetensis is very closely allied to A. Praini, a native
of upper Assam, but differs from it in its entire, not 3-lobed lip,
and in its somewhat smaller flowers. The wings on the claw of
the lip of A. benguetensis are very similar to those of A. Prainu
as figured in plate 2192 of Hooker’s Icones.

ing several filamentous roots at base, reddish (according to field
notes), with scattered scarious, acute or obtuse bracts. Flowers
white in loose racemes, subtended by short triangular-ovate, acute,
eymbiform bracts, which are much shorter than the 5 mm. long,
slender pedicels. Ovary about equal to the pedicel in length. In
fruit the pedicel becomes extraordinarily elongated, attaining a
length of 10 cm. or more. Labellum flabelliform, cuneate at base,
about 4 mm. long, with a transverse verrucose callus on the claw,
and with scattered verruciform papille along the disc. Sepals and
petals adherent, forming a tubular perianth, 6-7 mm. long. Col-
umn about 4 mm. long, semi-terete for two thirds of its length,
the apical third complanate, slightly winged.

The elongation of the pedicel after pollination of the flower is
a most interesting characteristic of this species. According to Mr.
Hemsley, the pedicels grow out sometimes as much asa foot in
length. Owing to this development, the elongated pedicel appears
to be a part of the stem. Both collections on which my observa-
tions are based were made in the vicinity of bamboos. This is
noteworthy, as Didymoplexis pallens has usually been found about
clumps of bamboos, and would seem to be a saprophyte or partial
saprophyte. Mr. Hemsley suggests that the elongation of the
pedicel serves the purpose of carrying the ripening fruit above
the decaying vegetable matter in which the plant grows. For an
entertaining account of D. pallens and the synonymy of the
genus Didymoplexis, reference should be made to the Journal

of the Linnzan Society 20: 308 (1884).

S. sinensis is an extremely variable species in the foliage and
in the form of the lip, consequently numerous species and varieties
have been recognized among its many forms by some authors only
to be reduced by others. Taken altogether, the species of the sec-
tion Euspiranthes seem to be remarkably plastic under the influ-
ences of environment, and adapt themselves readily to the most
diverse conditions of soil and climate.

Etairia rubicunda. It is doubtless like Lindley’s Rhamphidia

section Flaccide, to which C. sparsa belongs, nor to the sec-

belong most naturally in the Erectz, and to this section I refer it

The type specimen in Lindley’s Herbarium collected by Cuming
in the Philippines is most inadequate for a sure diagnosis, as the
flowers are missing. The drawings made by Lindley, however,
serve in a measure to assist in determination. The terminal lip-
lobe in Lindley’s specimen appears to have been narrower than in
the specimens collected in Mindanao by Bolster, and the lateral
lobes somewhat shorter. In other respects the material on which
my determination is based agrees too well with Lindley’s to be
identified as anything else.

DENDROCHILUM Bl.

The Philippine Islands are rich in species of this genus. The
greater part of the species described below belong to the section
of which Dendrochilum tenellum is the type. That is, they want
the column appendages which are variously described as wings,
arms, or teeth, and are characteristic of such well-known plants as
D. glumaceum, D. Cobbianum, and D. filiforme, cultivated for
the beauty of their elongated drooping racemes.

Dendrochilum, as originally understood by its founder, Blume,
was divided into two sections, one characterized by a lateral, the
other by a terminal inflorescence. These sections were recognized
as distinct genera by Bentham, who published them as Dendro-

ORCHIDACEZ 77

chilum and Platyclinis, respectively. Pfitzer maintained this divi-
sion. Later, J. J. Smith, in his review of the genus published in
1904, combined them, on the ground that lateral or terminal posi-
tion of the inflorescence could not stand as a generic character.
When it was learned that the obscure genus Acoridium, which
its authors, Nees & Meyen, assigned to the Philydracex, is con-
generic with Platyclinis, Mr. R. A. Rolfe, with the understanding
that Dendrochilum and Platyclinis are distinct, renamed some
thirty or more species of the latter genus, placing them in Acori-
dium, — which name by the rule of priority displaced Platyclinis.
Viewed from every point, the generic limits of Blume’s Dendro-
chilum cannot be fixed with surety until a more exhaustive study
of the species now known has been made than has heretofore been
attempted. The Philippine species form a remarkably well-con-
nected series, both as to vegetative and as to floral parts, and
form a natural group which may for convenience be divided into
three sections; namely, Eudendrochilum, with laterally produced
inflorescence, Platyclinis, with terminal inflorescence and winged
or toothed column, and Acoridium, with terminal inflorescence
and wingless column. The last of these sections is perhaps the
most remarkable for diversity of habit and floral conformation.
With few exceptions, the middle lobe of the labellum is smaller
than the lateral lobes, and the plants are for the most part of
dwarf habit. Although in my studies of the group I have been
inclined to adopt the treatment of Bentham and of Pfitzer, recent
investigations have led me to believe that the most rational treat-
ment is that advocated by J. J. Smith.

The section Dendrochilum is placed near Bulbophyllum in Pfit-
zer’s system of classification, thus being far removed from the
section Platyclinis, which is placed near Celogyne. As the lateral
inflorescence of Eudendrochilum by its rarity seems to be an ano-
malous characteristic, as the terminal inflorescence of Platyclinis
on the other hand is represented by many species, and seems there-
fore to be a normal characteristic, and as the floral character of
both sections indicates close affinity, not only with each other, but
with the Celogynine, I have assigned the genus as now consti-
tuted to the Celogynine rather than to the Bulbophylline.

78 ORCHIDACEZ

The following brief generic characterization becomes necessary
in view of recent additions to the number of species : —

Sepals and petals free, spreading, equal, or the petals sometimes
broader than the sepals. Labellum sometimes slightly saccate at
the base, often with elevated lines or keels on the disc, entire, or
2- or 3-lobed, the lateral lobes spreading or erect, often with
rounded calli at their bases. Column elongated or very short,
simple, or with wings or teeth produced from the base, middle,
or tip, and with a terminal entire or variously toothed or crenate
wing behind the anther ; anther small, 2-celled. Pollinia 4, waxy.
Rostellum prominent. — Epiphytes with tufted semi-fusiform or
rounded monophyllous pseudobulbs, clothed with searious sheaths.
Leaves various, terete-filiform to broadly lanceolate, convolutive
or duplicative in the bud. Flowers white, green, yellow, or brown-
ish red, distichous. Racemes often drooping, remarkable for the
elumaceous scarious bracts with involute margins which conceal
the pedicel and ovary.

of a leaf-bearing pseudobulb.
This species is in a way a link
between the sections Acoridium

acute, 3-nerved, 3 mm. long, 1.5 mm. wide. Upper sepal nar-
rower, oblong, 3 mm. long, 1 mm. wide. Petals rhombic-oblance-

3-lobed or trifid ; lateral divisions largest, oblong-falcate, obtuse,
with a minute callus at the base of each near the sinus formed
with the oblong, obtuse middle lobe, which is 1 mm. long. Col-
umn much like that of D. tenellum.

An interesting addition to the grass-leaved division of the sec-
tion Acoridium. From D. tenellum and D. sphacelatum it is at
once distinguished by its stricter habit, thicker, triangular leaves,
larger flowers, and very different lip. The flowers at the summit
of the raceme begin to expand first, a character which does not
hold in D. tenellum, D. sphacelatum, or D. graminifolium, in all
of which species the lowermost flowers are the first to bloom.

yellow fragrant flowers which turn deep reddish brown when dry.
Pseudobulbs stem-like, fusiform, 7-8 em. long, strongly grooved
when old, clothed with elongated, tubular, maculate, acute, closely

mm. through, bracts glumaceous, clasping the flowers, about 2 mm.
long. Flowers about 2 mm. apart in rather dense, distichous
racemes. Lateral sepals lanceolate, acute, 3-nerved, slightly con-
duplicate at the apex, 4.5 mm. long, 2 mm. wide. Upper sepal
similar to the laterals, narrower, about 4 mm. long. Petals lanceo-
late, acute, 3-nerved, broadly clawed, 3 mm. long, about 1.5 mm.
wide. Labellum 3-lobed, H-shaped ; lateral lobes oblong, broad-
ened toward the end, with an auricular or rounded lobe at the
base on the outer margin; middle lobe or division oblong, with a
sharp mucro at the tip, with a thickened, transverse ridge at the
base, which passes into two truncate calli, one at the base of each
lateral lobe. In the depression at the centre of the lip is a minute
callus on the median nerve. Column less than 1 mm. long, stout,
similar to the column of D. tenellum.

In D. graminifolium we have an interesting and instructive
transition between the filamentous-leaved D. tenellum and the
broad-leaved D. venustulum and D. pumilum forms of the section -
Acoridium. The fleshy flowers, which are nearly opaque, and the
very complex lip of D. graminifolium distinguish it very clearly
from its near allies. The character of the lip is worthy of special
attention, as the structure of the calli is more like that of the calli
of D.venustulum and its allied species than like the calli of D. tenel-
lum, thus forming a striking transition between the two groups.

the apex, passes at its basal margin, or rim, into thickenings, or ©
calli, one on each side at the sinus formed by the lateral and middle
lobes ; lateral lobes from sinus to apex, 1 mm. long, 1-nerved.

While D. tenwifolium is closely allied to D. tenue and D. parvu-

Lateral sepals linear-lanceolate, acuminate, acute, 3-nerved, 3
mm. long, 0.9-1 mm. wide. Upper sepal similar to the laterals.

Labellum 3-lobed; lateral lobes diaphanous, semi-crescentiform,

similar to that of D. tenellum.

D. tenue in habit forms a connecting link between the grass-
leaved D. graminfolium and the broad-leaved D. venustulum.
The lip, however, is more like the lip of D. tenellum. From Dr.
Schlechter’s description (Bull. Herb. Bois. ser. 2, 6: 302, 1906)
of Platyclinis microchila, said to have come from the Philip-
pines, this species — which under my view of the genus becomes
Dendrochilum microchilum (Schlechter) Ames—and D. tenue
appear to be very closely allied.

D. parvulum, which is the smallest member of the genus known
to come from the Philippine Islands, resembles closely D. tenue,
though this is a larger species, with longer leaves, more slender,
longer pseudobulbs, longer racemes and narrower, 3-nerved sepals.
The leaves of D. parvulum do not taper at the base so abruptly

3-lobed, from base to tip of mid-lobe 1-1.5 mm. long; lateral
lobes faleate, obtuse ; middle lobe quadrate, rounded at the angles,
with a tooth or mucro at the apex. At the base of each lateral
lobe is a thickened callus-like plate, and near the middle of the
lip a small tubercle.

D. recurvum is most nearly allied to D. pumilum Reichb. f.,
although much larger in foliage, and quite different from it in habit.
The flowers are fleshy, nearly opaque, and red-brown when dry.
The recurved pseudobulbs, which arise from a creeping branched
rhizome, and the densely spotted sheaths, which clothe the imma-
ture pseudobulb and conceal the petiole and leaf-base, are char-
acters which distinguish this species clearly from all other species
of Dendrochilum thus far discovered in the Philippine Islands.

According to field notes the flower
in a fresh state was white with red
centre. From this statement it is
highly probable that the sepals and
petals were white and the lip of a
reddish or purplish color. The stouter
rhachis, more strict inflorescence, and
very different sepals are characters
which serve readily to distinguish
D. simulacrum from D. pumilum.
From D. affine it is clearly distin-
guished by the middle lobe of the lip being smaller than the lat-
eral lobes. Both D. pumilum and D. affine possess a flexuose
almost filiform peduncle, which serves to separate them at a
glance from D. simulacrum.

DENDROCHILUM PUMILUM

My description of Dendrochilum pumilum is taken from a
tracing and from a flower of the Cuming plant (no. 2102) in the
herbarium of the British Museum. Here I refer the specimens
collected on Mt. Banahao, Prov. Tayabas, Luzon, October 19, 1904,
by H. NV. Whitford (no. 948), and in the Lamao Forest Reserve,
October, 1906, by #'. W. Foxworthy (no. 1637). The leaves are
narrower than in the Cuming plant, the lateral sepals are nar-
rower, and the lateral lobes of the labellum somewhat different.

D. pumilum, D. simulacrum, and D. affine are all very closely
related, although quite distinct. So far as I can judge from the

96 ORCHIDACEHZ

few specimens I have examined, I do not feel justified at present
in regarding these species as components of one polymorphic
species. The following supplement to the key will help to distin-
guish them :—

Middle lobe shorter, or only slightly longer, than the laterals.

Median callus conspicuous. D. pumilum.

DeEnDROcHILUM HuTcHINSONIANUM

D. Hutchinsonianum belongs in the same group with such spe-
cies as D. philippinense, D.recurvum, and D. pumilum. It is by

ORCHIDACEHZ 97

far the largest species of this group now known. The elongated
pseudobulbs and comparatively short peduncle, which is many times
shorter than the mature leaves, distinguish the species very well.

Epiphytic, odorless, in dense mossy thickets on exposed ridges,
at an elevation of 8000 ft. on Mt. Halcon, Mindoro, November
20, 1906, #. D. Merrill (no. 5813).

19. D. PHILIPPINENSE Ames supra, p. 12, t. 23. — Acori-

Pseudobulbs 2 em. long, somewhat pyriform, monophyllous.
Sheaths inflated, nigropunctate when dry, round, acute at the apex.
Petiole 5-6 cm. long, slender. Leaf oblong-lanceolate, acute,
strongly 5-nerved, 8.5-11 cm. long, 16-23 mm. wide, broadest
above the middle. Peduncle below inflorescence shorter than
the petiole and leaf, or longer, 12-16 em. long, slender. Jnjlores-
cence 5-10 em. long, 1 cm. through. F/owers in a dense raceme,
about 2 mm. apart. Bracts glumaceous, longer than the ovary,
2.5 mm. long. Flowers bright yellow, emitting an odor which
recalls the smell of freshly sawed pine lumber. Lateral sepals
oblong-lanceolate, acute, 4.5 mm. long, 2 mm. wide, 3-nerved.
Upper sepal similar, narrower, 4.5 mm. long. Petals rhombic-ovate,
acute, 3-nerved, 3.5 mm. long, 2.5 mm. wide. Labellwin 3-lobed,
lateral lobes linear-crescent-shaped, obtuse, erect, 1 mm. long, much
narrower than the broad oblong-lingulate middle lobe, which istrul-
liform when not flattened out, blunt at the apex, and thickened at
the base. Column exalate, 9 mm. long, stout, fleshy ; apex rounded.

This very distinct species belongs to a group of odd forms which
appear to have equal affinity with the sections Platyclinis and
Acoridium.

Pseudobulbs slender, pyriform, about 2.5 em. long. Leaves
9-14 em. long, 7-18 mm. wide, oblong-lanceolate, acuminate,
acute. Petiole 4-7 cm. long. Peduncle below inflorescence
shorter than the leaves, flexuose. Bracts glumaceous, 3-4 mm.
long. Flowers yellowish, odorless. Lateral sepals ovate-lanceo-
late, acute, 3 mm. long, 2 mm. wide. Upper sepal oblong-ovate,
obtuse or subacute, 3 mm. long. Petals ovate-acute, 3-nerved.
Labellum 3-lobed ; lateral lobes minute, rounded, basal ;. middle
lobe relatively very long, 2 mm. wide, semi-orbicular, about 1 mm.
long, trituberculate, with a tubercle on each side at base near the
sinus formed by the lateral lobes and with a papillate tubercle
between them. Column stout.

The lip, although unlike that of every other species of the
section Acoridium, is of great interest inasmuch as the tubercles
are in character and location similar to those of such species as
D. pumilum and D. venustulum. In habit the plant resembles
D. Whitfordu and D. philippinense.

wide. Upper sepal oblong, broadest above the middle, obtuse,
3-nerved, 3 mm. long. Petals broadly cuneate-obovate, broadest
above the middle, 3-nerved, obtuse or subacute, 2 mm. long,
slightly more than 2 mm. wide. Labellum contracted-sagittate,
3-lobed ; the middle lobe bluntly apiculate or obscurely 3-lobed ;
the lateral lobes blunt and rounded, with a large truncate tuber-
cle at the base of each near the outer margin ; on the median line
or disc of the lip a minute, very obscure papilla. Colwmn short,
with a very prominent protuberance in front.

In the herbarium of the Bureau of Science at Manila this species
and D. ocellatum are mounted on the same sheet. Both species
were collected by Mr. Merrill at the same time. Only four plants
were found, two of each species. D. oliganthum belongs to that
group of species which have the lateral lobes of the lip much
smaller than the middle lobe, and which merge with D. Whit-
fordu and D. ocellatum.

of the lip are nearly erect. — The above description, based partly
on the type and partly on additional material, is given to supple-
ment Mr. Rolfe’s description published in fascicle 1 of this work.

0.5 mm. in diameter, naked, without imbricating bracts at the
summit below the inflorescence, equalling the leaf or slightly

flowered raceme, 1 dm. long, 1.5-2 em. through. Floral bracts
linear-lanceolate, acute, about 3 times longer than the ovary and
pedicel, 4-7 mm. long, the slender awn-like apical portion up-
curved. Flowers 4 mm. apart. Lateral sepals linear-lanceolate,
acuminate, acute, carinate, 3-nerved, 9 mm. long, 2 mm. wide,
spreading. Upper sepal similar to the lateral ones, of equal
length with them. Petals oblong-lanceolate, microscopically and
irregularly toothed along the margin, acute, 3-nerved, 6 mm. long.

Labellum with 3 thickened nerves, ecallose, 5 mm. long, 3-lobed,

apex minutely crenulate, about midway in front a membranaceous
protuberance.

This very distinct species, which clearly shows its affinity with
D. Kingui (Hook. f., Icones Pl. 2015) J. J. Smith and with D.
exalatum J. J. Smith, from which it is readily distinguished by
its very different labellum, is represented by two collections made
by Elmer D. Merrill on Mt. Data, on the island of Luzon. It is
a most interesting addition to the group standing between the sec-
tions Platyclinis and Acoridium, having the habit of the former
and the gynostemium of the latter.

D. palawanense is most closely allied to D. rufum (Rolfe) J. J.
Smith and D. Kingii (Hook. f.) J. J. Smith, and with these species
forms a small group with tooth-like rather than wing-like lateral
arms to the column. In D. Kingiz the column teeth are not basal
as in D. rufum and D. palawanense. D. palawanense has larger
flowers than D. rufum, and from dried specimens they appear to
have been cream-colored. The auricular basal lobes of the labellum
in D. palawanense form a distinguishing character. In habit the
plants resemble D. wncatum Reichb. f. and D. cobolbine Reichb. f.

D. latifolium is readily distinguished from D. glumaceum, to
which it bears a striking habital resemblance, by the longer peti-
oles, pentangular cuneate acute bracts, erose-margined lateral
lobes of the lip, and by the arms of the column, which in D. lati-
folium are basilar, while in D. glumaceum they are at or near the
summit of the column.

DENDROCHILUM MAGNUM

To this species I refer two series of specimens collected by
KE. D. Merrill on Mt. Halcon, in the island of Mindoro. The label-
lum is in no sense 3-lobed at the apex, but except for this is in
conformation very much like a drawing in Lindley’s herbarium at
Kew, labelled D. magnum. If I were positive that the 3-lobed
apex was the result of anomalous development or injury, I would
have no feeling of hesitation regarding my determination. The
sulcate disc, the prominent rib that gives the labellum a carinate
aspect when viewed from beneath, and the very large flowers are
all much like the figure in Lindley’s herbarium. Furthermore,
the 3-lobed apex is not at all characteristic of the section Platy-
clinis, to which D. magnum belongs. Although my conclusions
are purely conjectural, I cannot convince myself that it would be
wise to refer my specimens to any other species beside D. magnum,
or to describe them as a new species at this time.

D. glumaceum usually emits, when dry, an odor recalling that
of slippery-elm (the inner bark of Ulmus fulva). It is the most
commonly cultivated of all Dendrochilums, its drooping racemes of

fragrant white flowers attaining a length of from 10 to 18 em. or
more. In my herbarium there is a specimen with branching
racemes. From D. latifolium it is readily distinguished by the
roundish mid-lobe and entire
lateral lobes of the lip, and
by the arms of the column
arising from the summit.
From D. Cobbianum it is
more readily distinguished,
as that species has a flabel-
late, obscurely 3-lobed lip.

mm. long, linear-lanceolate, with
a slender awn-like tip. Flowers
resupinate in a distichous raceme.
Sepals and petals linear-lanceo-
late, prolonged into slender tips,
the former about 1.5 cm. long,

AppEnpum. — The following species, which has come to light too
late for insertion in its proper place, should here be described.

D. (§ Acoridium) LUZONENSE sp. nov. D. Williamsii Ames

valde affine. Psewdobulbi cylindracei, graciles, circa 1 dm. longi,
2 mm.in crassitudine, vaginis tubularibus, arcte appressis, acutis ves-
titi. Folia linearia, 1.3-3.5 dm. longa,
acuta, conduplicata, a nervo medio ad
marginem 1.5 mm. lata. Pedunculus
emergens 2-4 em. ab apice folui, fili-
formis, gerens racemum distichum flori-
bus flavis. Racemus superans apicem
fol, 3-6 em. longus. Bractee inflo-
rescentia 3 mm. long, obtuse, pedi-
cellum brevem et ovarium multo exce-
dentes. Sepala lateralia lanceolata,
acuminata, acuta, 3-nervia, 3.54 mm. eee
longa, circa 1.5 mm. lata ad basim.
Sepalum dorsale anguste lanceolatum, 3.5-4 mm. longum. Petala
sepalo dorsali similia, 3 mm. longa, aliquantum dentata. Labellum
1 mm. longum, 3-lobatum; lobi subzequales; laterales late sub-
faleati, erecti, circa 0.5 mm. lati; medius apiculatus, aliquantum
conduplicatus, explanatus subquadratus, ad basim bicallosus. Co-
lumna minuta, sectioni propria.

In habit D. luzonense recalls D. Williamsii, which appears to
be its nearest affinity. It differs from that species in the general
conformation of the labellum, and in its lanceolate petals. D.
graminifolium would seem to be, in the form of the labellum,

122 ORCHIDACEZ

a near ally of the present species, but the very different lateral
lobes at once distinguish it, while its broader flat leaves give no
room for confusion with D. luzonense.

Orch. Pl. 20.

Plants foliose, varying in height from 12 to 30 cm. or more.
Stems short, thickened, bearing from four to six lanceolate, acu-
minate, acute, nervose leaves, which are from 6 to 20 em. long and
3-6 cm. wide. Peduncle with raceme up to 30 cm. long, conspicu-
ously bialate. Bracts linear, acute, the lowermost often 1 em. long.
Flowers yellowish green, numerous, in a rather loose, elongated
raceme. Lateral sepals 4mm. long, obtuse. Petals linear-oblong,
5.5 mm. long, 1 mm. wide. Labellum ovate, sagittate, abruptly
contracted into the bilobed, obtuse apex.

The material on which my determination is based agrees with
the type of Microstylis biloba Lindl. In the Kew herbarium a
specimen collected in central Luzon by Loher (no. 442), which
agrees perfectly with my material, is labelled WZ. carinata Reichb. f.
Somebody, presumably Reichenbach, has written on Lindley’s spe-
cimen of MW. biloba, “Is the lip really bilobed?” Lindley’s drawing
agrees almost perfectly with my specimen, and shows a distinctly
bilobed lip. From my studies of material which has been referred
to Mf. carinata, it would seem that the bilobed lip is a constant
character.

CESTICHIS GRACILIS

ORCHIDACEH 137

Cestichis gracilis is the smallest species of the section so far
known from the Philippines. It is readily distinguishable by its
very narrow leaves and slender pseudobulbs.

Mt. Mariveles, Prov. Bataan, Luzon, January 31, 1904, H. B.
Copeland (no. 274).— Mt. San Isidro, Prov. Rizal, Luzon, Janu-
ary 10, 1907, Maximo Ramos (no. 1782).

Cestichis disticha (Thou.) Pfitzer was collected by E. D. Merrill
on Mt. Halcon, Mindoro, in November, 1906. In habit it resem-
bles very closely C. gracilis. C. disticha is well characterized by
spathulate petals and a quadrate apiculate labellum. My concep-
tion of C. disticha is based on a specimen collected by Thwaites
in Ceylon (no. 2359), and on a specimen, of which I have a photo-
graph, in the Leiden herbarium, which is stated to be “ex herb.
Thouars.”’ For further details as to the occurrence of C. disticha
in the Philippines my paper, Orchidacew Halconenses, in the Phil-
ippine Journal of Science (Botany, 1907), should be consulted.

C. longipes and C. vestita are closely related species, and so
similar in general aspect that the one might readily be mistaken
for the other. C. vestita has a distinctly bilobed or deeply emar-
ginate lip which distinguishes it clearly from C. longipes which
has a lanceolate undivided lip.

hands. The flowers are imperfect. The following description is
drawn from specimens collected by Mr. R. S. Williams in central

the leaves are much shorter, and with specimens found in Minda-

nao by F. H. Bolster.

Reichenbach’s account of the labellum describes well the la-
bellum of the plants collected by Williams and Bolster, although
the styliform processes were not observed. Regarding these Rei-
chenbach was uncertain, and as the material on which he worked
was not in good condition, he may have been mistaken concerning
them. The specimens gathered by Bolster match well in habit the
specimens collected by the Wilkes expedition.

stouter species, with the leaves strongly
grooved on the upper surface and several
times shorter than the stems. Although
there is very little in Blume’s original
descriptions to separate the species, his
specimens in the Leiden herbarium clearly
show their differences. Reichenbach in

CALANTHE LYROGLOSSA

This extremely rare plant was originally described by H. G.
Reichenbach f. in Otia bot. Hamb. from material collected in
Luzon by the United States exploring expedition commanded by
Captain Wilkes. Reichenbach’s description is inadequate, in fact
misleading. The specimen in the Gray herbarium, which passed
through his hands and on which he based his description of C.
lyroglossa, is in a fair state of preservation. It consists of a leaf
and a flower-shoot. I have examined the flower carefully and
give herewith a camera lucida drawing. If it were not for the
authenticity of the specimen, there would be room to doubt that
it was the subject of the brief description which Reichenbach pub-
lished in his paper on the orchids collected by the Wilkes expe-
dition. The labellum is neither lyrate nor distinctly pandurate
according’ to my conception of these terms, nor is the anterior divi-
sion transversely ovate and acute. The Palawan material collected

158 ORCHIDACEH

by F. W. Foxworthy is a counterpart of the specimen in the
Gray herbarium in the conformation of the flower. The single
leaf of the type measures 52 cm. long, 5.3 em. wide.

To this species it seems best to reduce C. furcata Batem. on the
ground that C. triplicata is extremely variable. The labellum
characters on which great reliance has been placed for a distine-
tion between C. furcata and C. triplicata have little if any sys-
tematic value, and the lateral lobes and terminal lobes may often
be subequal. Here I refer the specimens placed under C. furcata

ing obliquely forward, distinctly quadrangular, concave between
the angles, often wrinkled or furrowed horizontally, surface smooth
or shining, yellow or orange-yellow, along the obtuse angles suf-
fused with green, the younger pseudobulbs clothed with yellowish,

striated, chartaceous bracts which become rufous with age and
eventually fall away. Leaves thick, of firm texture, smooth, ellip-
tic-oblong, subsessile, 9-12 cm. long, 3-4 em. wide, about twice
longer than the pseudobulbs. Peduncle terminal, wand-like, erect,
about 2 mm. thick near the base, sheathed at intervals with dull
reddish, 15 mm. long bracts. Jnflorescence a loose, simple and
graceful raceme, often exceeding 2 dm. in length. oral bracts
spreading, 11-18 mm. long, linear to oblong, obtuse, scarious,
slightly more than half as long as the slender pedicel and ovary.
Flowers T-20 or more, 4.5—5.5 cm. across when spread out. Sepals
linear-lanceolate, acuminate, acute, up to 3 cm. long, and at base
5-6 mm. wide. Petals similar, but rather more oblong and shorter.
Labellum deeply 3-lobed, about 18 mm. long ; middle lobe broadly
lanceolate, acuminate, 1 cm. long, separated from the triangular-
ovate lateral lobes by a narrow isthmus; dise with 3 raised nerves
which converge near the base of the middle lobe. Mentum obtuse,
5 mm. long. Colwmn 6 mm. long. According to field notes the
flowers are yellow and white. In dried specimens the lateral lobes
of the lip are of a very deep orange or reddish yellow, while the
petals and middle lobe of the lip are of a pale or whitish yellow.

As stated by Mr. R. A. Rolfe in his description, this Dendro-
bium is a near ally of the Javan D. cymbidioides described origi-
nally by Blume (Bijdr. 332) as Desmotrichum cymbidioides. It
was collected for the first time in May, 1904, by Thomas E. Borden
and H. N. Whitford, in the vicinity of the Lamao River, Mt. Mari-
veles, Province of Bataan, Luzon, in the Philippine Islands, and in
April, 1905, it was again found near the same locality by Elmer
D. Merrill, who sent a living specimen to North Easton. In gen-
eral aspect the plants resemble Dendrobium cymbidioides very
closely and might pass as luxuriant forms of that species, if it were
not for the very different lip and the acuminate sepals and petals.
Aside from its botanical interest Dendrobium acuminatum pro-
mises to be a valuable horticultural acquisition, worthy of importa-
tion and cultivation, because of its graceful racemes, numerous
flowers and compact habit. According to Mr. Merrill the plants

172 ORCHIDACE

grow in a region where for a part of the year the air is extremely
humid and at other times extremely dry. In March, when the
specimen which Mr. Merrill sent to me was collected, the species
seemed to be in a dormant state. (Cf. D. Lyonii, p. 177.)

D. Lyonii differs from D. acuminatum in its roughish pseudo-
bulbs which are minutely pitted when dry, in its larger leaves,
shorter pedicels, longer floral bracts and larger flowers, which are
described by the collector as being rosy carmine shading to deep
wine red on the labellum. This species has been figured in the
Gardeners’ Chronicle, ser. 3, 42: 210 (1907) under the name Den-
drobium acuminatum Rolfe.

My material is, without much doubt, D. macrophyllum Rich.,
although it differs in a few minor details from the common forms
of the species. According to the specimens I have seen from New
Guinea and other sources at the her-
baria of Kew and the British Museum,
D.macrophyllum appears to be a va-
riable, polymorphic species.

the young stems, near the summit. My description is taken from
a living specimen collected on Mt. Mariveles by #. D. Merrill,
which flowered in my greenhouses during March, 1907 (hb. Ames

Hutchinson (no. 4612).

The Mt. Mariveles specimen is in floral detail a counterpart of
those from Mt. Apo, but in habit the two sets are quite dissimilar.
This dissimilarity is most likely due to unnatural growing condi-
tions, as the Mt. Mariveles specimen has been grown in a green-
house. The leaves are broader and shorter than those of the type,
with short petioles, and are presumably more coriaceous ; the pseu-
dobulbs bear 2-4 leaves, which attain a maximum length of 2
dm. and a maximum width of 7 cm. The labellum of L. cylin-
drostachya appears to be retuse in some specimens.

more oblong labellum and less lanceolate leaves. HL. Hlmeri Ames,
which is a closely allied species, has shorter, broader leaves and
much smaller flowers. H. ringens Reichb. f., also from the Philip-

The specimens on which the above determination and descrip-
tion are based agree with Cuming’s Philippine plant (no. 2071)
preserved in the herbarium of the British Museum. On this
number of the Cuming collection Reichenbach f. based his de-
scription of LZ. vulpina in Bonplandia. LH. vulpina is allied to
several species which are most difficult to study in the dried state,
and which appear to approach each other rather too closely to be
kept distinct. The whole section Trichotosia to which /. vulpina
belongs deserves careful study in the field. There are several
specimens of this section in the herbarium of the Bureau of
Science which may represent L. velutina Lodd., and L. ferox B1.,
but I have omitted them from the present list as there is not
sufficient material with which to make satisfactory comparisons.

This species is unlike all others of the genus from the Philip-

seem that the racemes are produced in succession along the stem
from year to year, vestiges of peduncles remaining.

Owing to inadequate material there has been an unfortunate
misconception of this species, continued to the present time. That
the Epidendrum Myosurus of Forster was Dendrobium Myosu-
rus of Swartz and Willdenow is proved by synonymy. Lindley
bases his Oberonia Myosurus in part on the Forster plant, and
has been followed in this by subsequent authors. In Bonpl. 5:
54 (1857) Reichenbach describes an Hria Myosurus, on which
Lindley (Journ. Linn. Soc. 3: 61) bases his Phreatia Myosu-
rus. Reichenbach in FI. Vit. raises the Hpidendrum Myosurus
of Forster to Eria Myosurus, changing the Hria Myosurus of
Bonplandia to Z. stachyurus. The latter is identified by Smith
(Orch. Java 502) with Dendrolirium densiflorum of Blume, and
Phreatia densiflora Lindl., while Forster’s plant has not hereto-
fore been placed in Phreatia.

The material on which my determination is based agrees in habit
with Epidendrum Myosurus Forster, in the herbartum of the
British Museum. In habit it is similar to the Samoan or Navi-
gator’s Islands specimen collected by the Wilkes expedition, which
Reichenbach f. identified as Hria (Phreatia) Myosurus Reichb.
f., but which has longer, more slender, acute floral bracts and
appears not to be the same in floral conformation.

The specimens which I here refer to Lindley’s inadequately
characterized Lb. adenopetalum, have scapes 2 dm. long, with
about 20 flowers along the upper half, arranged in a loose raceme.
The plants are devoid of pseudobulbs, the scapes and leaves rising
from a thickened rhizome. ‘The oblong, coriaceous leaves (laminz
9-11 em. long, + 2 em. wide) have elongated, grooved petioles
about 1 dm. long. Lindley describes the petals of his specimens
as spathulate, and draws them so in the sketch which accompanies
his Singapore plant. My specimens have lanceolate petals, but in
habit agree very well with Cuming’s Philippine plants preserved
in Lindley’s herbarium. Unfortunately I have no record of the
petals of Cuming’s Philippine specimens which Lindley ascribed
to B. adenopetalum, and therefore have no means of settling
definitely the identity with B. adenopetalum of my Philippine
specimens, nor of segregating them from it. For the present it
seems advisable to consider the plants conspecific with Lindley’s
B. adenopetalum.

“Characterized by the masses of oblong elliptic, slightly com-
pressed pseudobulbs, clothed with silvery membranous sheaths,
and varying in length from eight to sixteen inches, more or less
furrowed when young, and deeply wrinkled when old. Each pseu-
dobulb bears at its summit from four to six deep green, persistent,
broadly lanceolate, acute /eaves, eighteen inches or two feet long. In
a wild state from sixty to seventy flowers, each about four inches
across, are borne in April on stout, erect scapes, which spring from
the base of the pseudobulb and are from five to seven feet tall.
The narrower petals vary in color from cream to greenish yellow,
and are handsomely blotched with dark brown or blackish purple,
the incurved tip of each sepal invariably having a large blotch of
the same color. The small Jip is pale creamy yellow, with a purple
stain outside at the base. The bluntly ovate incurved side lobes are
each transversed by seven sepia-brown parallel lines, and the disc,
which is covered with fine white hair, has two parallel elevated
keels or ridges which terminate in a small, hairy protuberance in
the center of the very small middle lobe, which is oblong in shape,
creamy white and lined with purple-brown, while the slender, arch- _
ing column is white, tipped behind and streaked in front with
purple. On each side of the yellow pollen masses, which show
through the anther case, is a small purple spot, thus giving the
column the appearance of some insect peeping out from between
the incurved side lobes of the lip.

“Tt is a peculiar fact, and one worthy of notice, that the first
five or six flowers at the base of the peduncle are always abnormal,
that is, abnormal in differing from the other flowers, but natural

in being always present. These lower flowers possess only two
sepals and two petals, all larger and more thickly blotched than in
the normal flowers. The column is also present and normal, but
the lip and third sepal are entirely absent.’’— John Weathers in

A specimen referable to this variety was placed under P. ama-
bilis Bl. in my first list of Philippine Orchids, published in fascicle
1 of this work. P. Aphrodite and P. amabilis have always been
more or less confused, the differences between them being very
slight and often obscure. In my herbarium an almost complete
series can be arranged which shows the gradual passage of one set
of characters regarded as specific into the other. The retuse apex
of the arms of the callus is about the only character which may
be relied upon to separate the Javan from the Philippine plants.

Plant up to 5 dm. high. Stem about 1 em. thick at base.
Leaves distichous, conduplicate, numerous, ligulate, up to 2 dm.
long, 11-15 mm. wide from the midrib to the margin. Peduncles
rather stout, bearing about 8 brown flowers, 4.5 cm. in diameter.
Bracts roundish or oblong-obtuse, 4-5 mm. long. Pedicel and
ovary about 4 em. long, slender. Lateral sepals 2.3 em. long, 11
mm. wide, obovate to oblanceolate, with a slender claw, obtuse or
subacute. Upper sepal ovate-lanceolate, 21 mm. long, 9 mm. wide.
Petals similar to the lateral sepals, 21 mm. long, about 1 ecm.
wide. Labellum 16.5 mm. long, spurred; spur 4.5 mm. long; lat-
eral lobes erect, quadrate-oblong, obscurely retuse, 5 mm. long,
about 2.5 mm. wide; middle lobe finely pubescent, hastate-oblong,
dilated at the apex into two dolabriform, fimbriate, diverging lobes
with a mucro between them; lobes 7.5 mm. long, 11 mm. wide
across the apex; fimbriations about 2 mm. long; oblong portion
of the middle lobe 4 mm. wide, 7 mm. long, with 5 raised nerves.
Column clavate, 8 mm. long.

This remarkable species has no near affinity. From all other
Vandas it is clearly distinguished by the halberd-shaped, fringed
lobes of the lip. I have a sketch in my herbarium taken from the
type in the Kew herbarium. The fringe on the terminal lobes is
represented in this sketch as being shorter than in my specimens,
but this difference is not sufficiently great to warrant a specific
or varietal distinction.

Although the material on which my determination is based has
been regarded by Mr. Loher as specifically distinct from all other
Vanda species, I am of the opinion that it represents a color variety
or form of V. tricolor. According to field notes the sepals and
petals are white, and the flowers nearly or quite odorless. Mr.
Loher says that the plants grow in high trees, where they form
heavy clumps.

TNIOPHYLLUM COMPACTUM
1, petal and sepals; 2, labellum; 3, anther cap;
4, column.

T. compactum appears to be intermediate, generically, between
Microtatorchis Schltr. and Geissanthera Schltr. The divisions of

248 ORCHIDACEHZ

the perianth are adherent as in Microtatorchis pusilla Schltr.,
though not united for so much of their length, while the bract-
like processes on the peduncle, though somewhat unlike those in
Geissanthera, certainly suggest that genus, as do the leaves of the
contracted stem. The same difficulty has been experienced in
assigning this plant to its proper genus among the segregates
of Teniophyllum which it seems must always occur where minute
distinctions are relied on in the conception of generic limitations
among plants; therefore it has been deemed best to retain this
new Philippine species in the genus Teniophyllum. The number
of the pollinia is perhaps the most salient character on which Dr.
Schlechter depends in establishing the genera Microtatorchis and
Geissanthera, but this character is often most difficult to observe,
while in herbarium specimens it is likely to be lost. 7. compac-
tum possesses 2 pollinia, which number removes it from the genus
Tzniophyllum, if Dr. Schlechter’s views are adopted, and places
it in either Microtatorchis or Geissanthera; a proceeding which it
seems to me would be warranted only after a more exhaustive study
of the thirty or more species of Tzniophyllum than has yet been
attempted.

denticulate-margined. To the synonymy given above many addi-

As the first specific name of this plant is not available, owing
to the Spiranthes plantaginea published by Lindley, it becomes
necessary to adopt the name given by H. H. Eaton in the Transyl-
vania Journal of Medicine in 1832, and this gives Spiranthes
lucida as a new combination.

dorsale simile. Petala linearia, obtusa,
1-nervia, 3 mm.longa. Labellum trulli-
forme, explanatum ovato-lanceolatum,
Maxaxis Nersonu acuminatum, obtusum, 2.5 mm. longum.

M. Nelsonii differs from Microstylis ochreata Watson, to which
it is nearly allied, in having a trulliform labellum. The labellum
of MV. ochreata is sagittate.

Type (no. 332832 in National Herbarium) from Sierra Madre,
30 miles north of Gunacevi, alt. 8000-9000 ft., State of Durango,
Mexico, August 18, 1898, Z. W. WVelson (no. 4782).

M. SPICATA Swartz Prodr. 119 (1788) and Fl. Ind. Oce. 3:
1441, t. 28, figs. a, b, c (1799) ; Microstylis spicata Lindley Orch.
Pl. 19 (1830); M. floridana Chapman FI. 8. U.S. ed. 1, 454
(1860), Ames Contr. Orch. Fl. Fla. p. 15, t. 6 (1904); Acroan-
thes floridana Greene Pittonia 2: 183 (1891).— The analysis of
the flower given by Swartz in FI. Ind. Occ. is not at all satisfac-
tory. The lobes of the labellum are over-accentuated, and the
laterals are drawn acute. The Jamaican specimen in the herbarium
of the British Museum collected by Swartz is rather taller than the
average.
