PREFACE

Durine his residence in Jamaica for twenty-one years as

_ Director of Public Gardens and Plantations, Mr. William
_ Fawcett gave attention to the botanical exploration of the
~ Island. He was specially interested in the Orchids, and, with

. the assistance of Mr. William Harris, Superintendent of the

Gardens and an excellent collector, a very fine collection

_ illustrating the family was got together. A beautiful series of

drawings from the living plants was also made under Mr.

Faweett’s direction by Miss Helen Wood. During one of

Mr. Faweett’s visits to England we agreed to collaborate in a
monograph of the Jamaican Orchids, and in 1904 an account
of the genus Lepanthes was published in the Transactions of
the Linnean Society. The work, however, proceeded slowly
until 1908, when Mr. Fawcett retired and came to England.
The permission of the Trustees having been obtained for the

_ publication of the work as a British Museum Catalogue, Mr.

SEA ae

Fawcett was fortunately able to devote himself to the task, and
I have given what time I could spare in the intervals of other
work, Though Mr. Fawcett has done the larger part of the
work of preparation, we have both been carefully through each
species. Our work has been greatly facilitated by the loan

_ of the Jamaican Herbarium, for which we are much indebted
_ to the Government of Jamaica.

As Mr. Fawcett is able to continue his work at the
Museum, it is proposed that the present volume shall form the
first part of a complete “ Flora of Jamaica.”

INTRODUCTION

Tue Island of Jamaica, the largest of the British West Indian
Islands, is 144 miles long and 30 to 40 miles broad. It lies
about 90 miles south of Cuba, and about 380 miles N.E. of
Honduras, the nearest part of the mainland.

“Jamaica is remarkable for the limited area in which very
many species are found, and for the wonderful contrasts in
neighbouring districts in geological structure and soil, in
elevation, in rainfall and in temperature.

“The Blue Mountains in the eastern end of the island
attain the highest elevations, rising to 7,423 feet. The distance
from the ridge to the coast on the north and south in a straight
line is about 20 miles. On the Blue Mountains and north to
the coast the north-east trade winds bring almost constant
rain throughout the year, the rainfall varying from 150 to
200 inches annually. From the ridge to the south coast the
rainfall decreases, and as the Blue Mountains run not directly
west but inclined towards the north-west, and as the prevailing
winds are from the north-east, the result is a decrease in the
rainfall in travelling along the coast from Morant Point to
Kingston ; thus from Morant Point to Morant Bay there is a
rainfall from 70 to 55 inches annually, then a belt 50 to 40 inches,
and then for a considerable distance to Kingston and beyond,
35 to 30 inches. The slopes of the mountains are frequently
precipitous, and there may be great differences in elevation, in

__ moisture and temperature within short distances. or instance,

one may pass from the southern slopes of the John Crow Peak
of the Blue Mountains at about 5,500 feet, where xerophytic
_ conditions sometimes occur and often cold nights with tempera.
' ture down to 50° F., round the shoulder to the north, and
straight down 2000 feet to the Mabess River, where there is

almost constant rain, continual moisture from a perennial stream,

and a warm temperature at nights. The geological structure of

Vill ORCHIDS OF JAMAICA

the district consists chiefly of brittle shale, easily decomposing,

with occasional masses of coral limestone, marble, granite, &e.,

interspersed.

“There is a range of mountains close to the east end,
running in a northerly and southerly direction, and rising to an.
elevation of 2,100 feet. The coast in the neighbourhood is’
rocky, and continues so for some distance to the west of Port
Antonio. These mountains, known as the John Crow Mountains
or Blake Mountains, are so wet, and the limestone rock is so
difficult to travel over, that it is believed only one white man
has ever crossed them. Nathaniel Wilson may have collected
on the slopes of these mountains on the east side, or on the
southerly slopes, some of the species that have not been found
since. The limestone rock of these mountains occurs over the
greater part of Jamaica, and in large districts it has disinte-
grated so as to form, as in the John Crow Mountains, such a
series of precipitous cliffs that it is impossible to travel through
it. The so-called ‘ Cockpit country ’ is of this nature, and it is
in such places that new species of plants may naturally be
looked for.” (W. F. in Urban, Symbol Antillane, vi. 86.)

The Orchids of Jamaica-are of special interest from the large
number of endemic forms which they include. The total
number of genera is 61, one of which, Homalopetalum, is endemic.
The total number of species is 194, of which 73 are confined to
the Island. There are also some endemic varieties. |

The most striking atlinity of the Orchid flora is with that of
Cuba, 82 species, out of a total of 121, which are not endemic,
occurring also in that island,.and of these 14 are restricted +o
the two islands. The aflinity with Hispaniola is apparently not
so marked, there being only 29 species known from both
islands, of which two, Epidendrum repens and Broughtonia
domingensis, occur nowhere else. The difference is due no doubt
to some extent to our greater knowledge of the botany of Cuba
as compared with that of Hispaniola, With the much better
explored island of Porto Rico, which lies further east beyond
Hispaniola, the affinity is apparently greater, there being
40 species common to Jamaica and this island, four of which |
are known elsewhere. only in Cuba. Ten species are common to
Jamaica and the Bahamas, and 15 to Jamaica and Florida, the
relation of which to the West Indies is very close. Passing

INTRODUCTION 1x

further east and south from Porto Rico, 38 species are common
_ to Jamaica and ene or more of the Lesser Antilles. Forty
species occur both in Jamaica and Trinidad, of which nine are
not recorded from the Lesser Antilles, but six of these are known
from Cuba, and three from Cuba and Porto Rico. Epidendrum
nutans has a somewhat remarkable distribution, being known
only from Trimidad, Venezuela and Brazil, in addition to
Jamaica.

The relationship with Central America is well marked; 37
species are common to Jamaica and some part of Central America,
and if we include Mexico the number is raised to 44. Of these
28 are also found in equatorial South America, of which sixteen
represent an element widely distributed over the West indian
and tropical American area. Of the sixteen which do not occur
in equatorial South America, four are confined to Jamaica and
Central America and ten to Central America (with Mexico),
Jamaica and Cuba,

The affinity with equatorial South America is also strongly
marked, 48 species being known to occur in some portion of
tropical South America and Jamaica. A number of these also
represent a widely distributed tropical American element occurring
more or less generally in the West Indies and Central America,
some few being also known from Florida and the Bahamas. If
we consider Trinidad as part of equatorial South America, six
of these forty-eight species occur nowhere else in the West Indies
except in Jamaica. These comprise three species of Hpidendrum
—E. verrucosum, known also only from Columbia, EZ. nutans from
Trinidad, Venezuela and Brazil, and E. imbricatum from Central
America and Brazil—and Brassavola nodosa, Mawillaria rufescens
and Cryptarrhena lunata from Central America and more or less
widely distributed in equatorial South America.

These six species which do not otherwise occur in the West
Indies, together with the Central American group already
_ referred to, probably represent an element of the Jamaican flora
_ associated with two former extensions of the land surface between

Cuba and Yucatan, and Jamaica and Honduras. The sea-

bottom between Jamaica and Honduras comes within the 6000
fathom limit and contains large banks within the 600 fathom
limit. If we include Jamaican species which occur also in the
Greater Antilles, there are twenty-four common to these and

x ORCHIDS OF JAMAICA

equatorial South America which are not found in the Lesser
Antilles and may also be associated with the extensions of land
already referred to. A south-eastern line of association with
equatorial South America through Hispaniola and Porto Rico is
without doubt represented by the series of the Lesser Antilles —
and Trinidad ; as we have mentioned above thirty-eight Jamaican
species occur in the Lesser Antilles and forty in Trinidad.

These facts of distribution are in accord with geological
evidence of a former linking up of Central America and Venezuela
by means of the line of the West Indies. |

“The Antilles are formed by the summits of a moutitath chain:
which separates the Caribbean Sea from the Atlantic Ocean and
the Gulf of Mexico. A second are running from Honduras
through Jamaica and the south-west of Haiti appears to join the
principal chain. Even the great deeps which occur in certain
places, as, for instance, between Virgin Gorda and Anguilla, do
not interrupt the continuous course of the mountain chain.”

‘“‘ With the slopes of the Mexican plateau in the State of
Oaxaca, says Seebach, the compact northern continent terminates..
To the south and to the east of the isthmus of Tehuantepec,
Central America commences, which already belongs to the
island world of the Antilles. ‘The mountain series of the
Greater Antilles, which further to the east in Porto Rico and
San Domingo—the eastern part of Haiti—forms a single main
chain, divides in the middle of the latter island, giving rise to a
southern branch which proceeds through the elongated peninsula
of Jacmel towards Jamaica and Honduras, and a northern branch
which extends beyond Cuba towards Yucatan . . . Is it merely
a remarkable accident that the Sierra Maestra, consisting of
crystalline schists and massive rocks and situated in the south-
east of Cuba (where the Greater Antilles reach their greatest
elevation of 2,338 meters above the sea), should run through
the Cayman group, the bank of Misteriosa, the Viciosas, and
Swan Island to the depths of the gulf of Honduras, and that
from the edge of this mountain ridges similarly constituted
should rise abruptly and proceed with constant strike into the
interior.’ ”—(Suess, “ The Face of the Earth,” Eng]. Transl. i. 543.)

Our knowledge of the flora of Jamaica starts with the work
of Sir Hans Sloane, who collected in the Island during a stay

INTRODUCTION xl

of fifteen months in the years 1687-89, and published the results
in his work on the Natural History of Jamaica (1707-25).
Sloane’s Jamaican plants occupy Vols. I. to VIII. of the Sloane
- Herbarium at the British Museum, and these volumes have
_ been carefully gone through in connection with our work on the
Orchids. The herbarium of Sir Joseph Banks, which became at
his death the foundation of the Department of Botany, included
collections from Jamaica by William MHoustoun (1729-33),
William Wright (1771-85), Roger Shakespear (1780-2), and
Francis Masson (1781), and also a large number of specimens
from Olof Swartz (1784-6), including types of many of the new
species published in his “ Prodromus” and elsewhere. Besides
' these and the later collections at the British Museum we have
worked through the material in the Kew Herbarium, which
includes the collections of James Macfadyen (1825-50), W
. Purdie (1843, 4), Nathaniel Wilson (1846-58), R. C. Alexander
Prior (1849, 50), W. T. March (1857, 8), and others.

We have to thank the Government of Jamaica for the loan
of the whole of the material contained in the Jamaican Herbarium,
the formation of which was begun by Sir Daniel Morris (1879-86)
--and was continued by one of us (1887-1908) with the very
efficient help of Mr. William Harris as collector. In this
connection special reference should be made to Mr. Harris's
- work as an indefatigable and successful plant-collector, to which
is owed a considerable increase in knowledge of the flora of
Jamaica. Our work has been greatly facilitated by the use of .
a fine series of drawings made at the Hope Gardens, Jamaica,
from the living plants, under the supervision of one of us, by
_ Miss Helen A. Wood ; many of these have been reproduced in
the plates at the end of the volume, for the large number of
which we are grateful to the Trustees of the British Museum.
We have also to thank Dr. N. L. Britton, Director of the
New York Botanic Garden, for specimens and for the loan of a
collection of Orchids made in Jamaica by Sir D. Morris. A
~ number of private individuals resident in or visiting the Island
have also contributed specimens ; most of these are contained in
the Jamaican Herbarium. By the kindness of Dr. Radlkofer
of the Royal Botanical Museum, Munich, we have been able
_ to work through the Orchids collected by H. R. Wullschlaegel
(1847-9). As Wullschlaegel’s specimens are cited by Grisebach

Xi ORCHIDS OF JAMAICA

in the “Flora of the British West Indies,” it has been
of interest to revise his determinations by comparison with ©
the original collection. Prof, Ignatius Urban of Berlin has
generously entrusted to us the volume of Swartz’s “ Ieones
Ineditx,” and has allowed us to cite the drawings. During the
preparation of our work Prof. Urban has given a detailed account
of the botanical exploration of Jamaica since the publication
of Grisebach’s “Flora” in his ‘ Symbole Antillane” (vi.,
pp. 70-131, 1909). To Prof. Cogniaux, who is elaborating the
Orchids of the West Indies for the “Symbole,” we are indebted
for the loan of specimens and helpful information.

Our descriptions of the genera have been drawn up with
special reference to the species which occur in Jamaica. _ For
measurements we have used the metric system, but for con-
venience of tourists we have added English measures for the
height of the plant and the size of the flower. The figure below
renders possible a ready comparison of the two systems, e.g.
2°5 cm. are equivalent to an inch, 2 mm. to ,), inch, and 1 dm.
to about 4 inches.

The J.P. (Jamaican Plants) numbers cited are those given by
Sir D. Morris to the species in the Jamaican Herbarium; the
numbers cited as Fl. Jam. (Flora Jamaicensis) are those attached
to specimens, as collected, later.

The mark “‘!” indicates that we have seen a specimen.

In order to conform to the international rule, which requires
that diagnoses of mew species shall be published in Latin,
descriptions of novelties have been inserted in the ‘J sins
of Botany,” and are quoted here from that work.

ORCHIDS. OF JAMAICA

OrcuHiIps are perennial herbs showing much variety in their
habit. They are either terrestrial, growimg in the soil, or
more or less epiphytic, that is, growing on stems or branches of
trees, on rocks, etc., often surrounded by a dense growth of moss.
In the simplest form of growth, the stem continually produces
new leaves at the apex, while the flowering shoots spring
from the axils of older leaves. This method, known as the
monopodial, occurs in some epiphytic orchids, as in Dichza,
where the internodes and leaves are both very short. In all
terrestrial orchids and many epiphytic, growth of the main axis
soon ceases, usually at the end of one season, while a lateral
shoot continues the growth next season. The apparent main
axis of the plant is then a sympodium, consisting of the basal
scale-bearing portions of successive shoots, the upper parts of
which are aérial and leafy. The shoots may end in an
inflorescence, or flowers are borne on special lateral branches.
The development of the sympodial rhizome governs the habit
of the plant. If the basal portion of the yearly shoot is short,
the successive aérial shoots are crowded and the habit is bushy
or clustered, whereas if the basal portions are lengthened a
creeping or climbing habit results.
In terrestrial orchids the basal portions of the annual shoots
form a thin or fleshy root-bearing rhizome (as in Spiranthes), or
_ a tuber is produced each year (as in Habenaria, Bletia). The
_ aérial stem is slender, bearing one to many foliage-leaves and
_ ending in a single flower or an inflorescence. The leaves are
_ inserted along the stem (cauline) or are clustered at the base
(radical).
The majority of epiphytic sympodial forms are pseudo-
| i bulbous ; that is, the stem is thickened to serve as a reservoir
of food and water. The pseudobulb consists of only one
_ internode and bears one or more leaves at its apex, or of several
5 internodes and bears leaves throughout its length, or bears
_ scales at the lower nodes and a terminal tuft of leaves. The
B

2 ORCHIDS OF JAMAICA

pseudobulb is of very various shapes, sometimes globose,
usually more or less elongated ; its surface is generally smooth
and shiny. In Pleurothallis and allied genera the shoots are
not thickened to form a pseudobulb, and bear a single leaf
which spreads at right — to the axis or apparently forms
a continuation of it.

The leaves are simple, generally sessile, and wither and
decay on the stem, or, as in most epiphytic species, separate
by a distinct joint. The margin is entire and the apex often
denticulate or unequally cut ; the venation is as a rule parallel.
In some cases the blade passes gradually into a stalk which
has generally a sheathing base.

At the basal nodes of the shoots leaf-scales are borne, wien
pass gradually into foliage leaves, or the latter may start a
The leaves are generally arranged in two ranks, one each sidle ‘of
the stem.

Léaves of epiphytic forms are generally thick and fleshy 3 $
and by a thick cuticle they aré adapted for storage of water. A
main root is never present ; its place is taken by adventitious
rdots which arise especially from the nodes and often show as
regular an arrangement as the leaves. In terrestrial orchids the
roots ‘are sometimes thickened to form ‘stores of ‘reserve material.
The air-roots of epiphytic orchids have a special development of
the ‘outer layers forming a sponge-like tissue (velamen), by which
water is absorbed for the plant from the atmosphere. Three
kinds of air-roots may be distinguished. ‘Clinging roots which
creep close to the substratum and aire inseparable from it;
absorptive roots, or branches of the fornmier which igrow into the
humus which collécts about the plant; and the finevaérial wits
which hang down sometimes toa» ‘considerable length.

The fiowers-are hermaphrodite and irregular. The periimnth
consists of an outer whorl of three sepals and an imner whorl of
three petals which alternate with the sepals. The odd-or median
sepal is normally on the lower ‘side of the flower and furthest
from the axis. The odd petal, which generally differs con-
siderably in size and shape from the ‘two lateral :petals ‘and «is
térmed the lip, is normally on the upper side ‘of ‘the flower next
the axis. This !position is, however, generally reversed by a
twist of the ‘ovary so that ‘the lip in the open flower is ‘on
the lower side. ‘The sepals are usually ‘smaller and less »con-
spicuous than the petals, but in some genera (as Pleurothallis,
Lepanthesand Brassia) they are much larger. They are free from
each other or more or less coherent ; in some génera, as ‘Pelewia and
Stenorrhyncos, the lateral sepals are-utiited at the base toformia
spur which in -Pelexia encloses ‘the -elongated *base of ‘the slip.
The: petals show'a-great variety in-form and :colour:; the lateral
pair are generally smaller than the lip. ‘The ‘lip which ‘is,asva

rule, the most conspicuous feature of the flower, is often large and
spreading, or has upwardly curving sides. It is simple (undivided)
or two- ae or four-lobed and generally bears on the upper face
thickened veins or swellings (calli), or fleshy warts, which are
often, as in Oneidium, large and conspicuous. The lip is some-
times produced at the base into a sac or spur, which may arise
partly from the axis of the flower. |
The most characteristic feature of the flower is the develop-
ment of. the receptacle, which at an early stage becomes
cup-shaped, and finally forms a hollow cylinder. The carpels
(three in number) arise as outgrowths from the edge of the cup,
on the interior of which the oyules are developed on three double
placental lines alternating with the carpellary outgrowths. The
perianth springs from the upper edge of the inferior ovary,
where there is often also an expansion of the axis known as the
foot. The lateral sepals are continued along the sides of the
foot, from the tip of which the lip springs at a sharp angle,
forming externally a chin, inside which at the base nectar is
often secreted. - ss i
_ The stamens and stigmatic surfaces are raised aboye the
perianth on an elongation of the floral axis known as the
column ; occasionally some of the other organs are raised up
on the column, as in Ponthieva, where the petals and lip are
arried up above the sepals. Comparative study of the orchid
wers among themselyes, and especially with those of other
families of Monocotyledons, suggests that the stamens are derived
from two alternating whorls, each of three members, the members
of the outer whorl alternating with the petals. The stamens are,
however, much reduced, and are represented in the great majority
of orchids by one anther, which is variously placed on or near
_ the apex of the column, and represents the median stamen of
the outer whorl, opposite the median sepal. There is generally
no trace of the other members of this whorl, but they sometimes
appear as small outgrowths on the side of the column; and the
lateral pair of the inner whorl is also often similarly represented ;
in Epidendrum Ottonis they are more or less fertile. The presence
of a single fertile stamen characterises the great majority of the
genera ; in the genus Cypripedium, not found in Jamaica, the
_ lateral stamens of the inner whorl are fertile, while the median
_ stamen of the outer whorl is.,represented by a large ptatnnode.
_ . Cypripedium has three functional stigmas ; but in Jamaican
orchids only the lateral pair are functional, the third is
sterile and forms ,the sostellum, which often plays an important
_ part in transference of the pollen. The stigmas form a smooth,
viscid, flat,or cushion-like area_on,the inner face, or sometimes on
the end of the column, or two distinct processes which jin

Habenaria are,borne on projecting style-like structures.

4 ORCHIDS OF JAMAICA

The form of the anther, its position on the column and the
means by which the pollen is transferred, vary widely in the
different genera. The anther contains two, four, or eight cells,
each of which contains a mass of pollen. The pollen masses
or pollinia are granular or powdery, breaking up into grains on
removal, as in Pogonia, Spiranthes, Vanilla, etc. ; or the grains
are united into packets by an elastic web as in Habenaria; or
waxy pollinia are produced by the formation of a strong common
covering round each mass as in Hpidendrum and allied genera.

The anther may stand erect and free on the top of the
column, as in Habenaria where it is strongly united to the
rostellum by its base, and does not separate from the column when
the pollinia are removed. Usually, however, the anther is
attached to the rostellum by its apex. In this case it may be
erect and stand behind the stigma in such a way that the rostellum
reaches its apex, as in Stenorrhyncos, and the filament is gener-
ally thin but strong enough to hold the anther in place after
removal of the pollen. In most cases, however, the anther is
not erect, but is placed horizontally or hangs on the inner face of
the column ; it usually separates so easily from the thin filament
that it falls when the pollen is removed. It lies along the
rostellum or is more or less enclosed within a special cavity
of it (clinandrium), or is in contact with it only at the apex.

The removal of the pollinia is generally effected by the help
of insects, which visit the flower for the sake of a sweet juice
contained in the sac or spur-like development or in the various
excrescences of the lip. Insects are attracted by the colour, form
and smell of the flower, the lip of which often forms an effective
landing-stage. The pollinia and stigma are so placed in reference
to the position assumed by the insect as to favour the carrying
off of the pollinia from one flower and its deposition upon the
stigma of another of the same species.

To ensure its transference the pollinia are often attached to
a stalk, which is associated with a sticky mass, the so-called
“gland.” Thus in Habenaria each anther-cell is produced into
a long process (anther-canal), the contents of which form stalks
(caudicles), to which are attached above the numerous packets ©
of grains forming the pollinia. Below, the caudicle is attached
to a gland formed from the rostellum. The anthers split open
longitudinally when mature, and the pollinia are drawn out by
the adhesion of the gland to the head or proboscis of an insect
visiting the flower. In other genera no definite gland is pro-
duced from the rostellum, but a quantity of viscid matter exudes
from it when touched, and serves to glue the protruding tips of —
the caudicles to the retreating object. In many genera the
pollinia are connected to the rostellar gland by a stalk (stipes or
pedicel), which is not a development of the anther, but of the

ORCHIDS OF JAMAICA o

upper face of the rostellum (as in Mazillaria). In some cases
_ short true caudicles are formed, by which the pollinia are
attached to the pedicels.

The ovary is generally somewhat cylindrical-ellipsoidal or
spindle-shaped, and often bears longitudinal lines, ridges, or
wings, which become further developed in the fruit.

The fruit is a dry capsule, except in Vanilla, crowned by the
withered remains of the flower, and opening usually by six longi-
tudinal slits, forming three broad and three narrow valves, which
remain united above and below ; in Harrisella they are free above.
In Pleurothallis there are only two slits. In Vanilla the fruit is
fleshy and pod-like. The seeds are innumerable and minute,
and contain a small rudimentary few-celled embryo enveloped
by a thin loose membranous coat, which varies much in shape
and colour. They are scattered by aid of hygroscopic hairs on
the interior of the valves, and are carried by the wind.

The family falls into two groups, a small one, Diandre, not
represented in Jamaica, with two or rarely three fertile stamens,
and a large one, Monandrex, with one fertile stamen.

The subdivision of the Monandrx was based by John Lindley
(The Genera and Species of Orchidaceous Plants, 1840) solely on
characters derived from the anther, the pollen, or the pollen-
distributing apparatus. Lindley recognised six tribes. E. Pfitzer,
who more recently elaborated the family in Engler and Prantl’s
Pflanzenfamilien (ii. part 6, 1889), criticises this arrangement,
which was practically followed by Bentham and Hooker in the
Genera Plantarum (iii. 1883), as depending too much on the
relation of the floral structure to insect visits for the purpose of
pollination, and too little on a general study of the whole plant.
He retains the Ophrydex which are characterised by the per-
sistent terminal erect anther (to which belongs Habenaria), but
subdivides the remainder into twenty-eight tribes, based on the

_. terminal or lateral character of the inflorescence, the develop-

ment of the leaf and stem, and the form and relative size of
the lip. We have followed the sequence of genera in Pfitzer’s
arrangement.

* The species name is generally spelt with a capital initial, Habenaria
being the name of a genus. Linneus, however, did not take the trivial
name from a generic name, as Habenaria was founded much later by
Willdenow (1805). As therefore the species name is not taken from a
generic name (see International Rules of Botanical Nomenclature et
Rec. x) it should begin with a small letter as in Linneus’s origina
description.

Since the publication of H. troyana, we have had the opportunity,
through the courtesy of Prof. I. Urban, of comparing flowers from .the
type specimen of H. eustachya Reichb. f. in Ber. Deutsch. Bot..Ges. iii.
274 (1885) from Porto Rico (Sintenis, no, 511b); this differs from H. troyana
in being smaller, with thinner, non-clayate sped mage a lip.
When describing H. troyana we, compared it with H.
which we suggested might prove identical with H. eae ee

Ames now (op. cit. 257) refers H. Sanbornii to H. eustachya, and aaiaidere |

H. troyana as probably the same species.

Stem leafless on main stem, thick, 1 cm. or more br., shrivelling very
much, to 5 or 6mm., when dry; internodes about 10 cm. 1.; adventitious
roots often twisting spirally like tendrils. Leaves 3-8 cm.1. Raceme with
8-12 sessile flowers, to 14 cm.1. Bracts below like the leaves, but much
smaller, above triangular, acuminate, 2--5cm.1. Ovary # as long as the

Swartz says, ‘‘flores albi . . . odor fortis Orchidearum.’’ Grisebach
quotes Wright as saying ‘‘perigonium rufescenti-virens, labello rubro-
marginato et punctato, mediano intus barbato.” We have not taken the
species name from Linnzeus’s Cactus parasiticus owing to the great
confusion in his references. In the Systema (1759) he describes C.
selene as ‘‘repens, teres, striatus, muticus,”’ referring to (1) Sloan.

am. 224, f. 3, 4, the specimen of which is in Herb. Sloane, and is
Vanilla claviculata Sw.; (2) Plum. Ic. 197, f. 2, probably a species of
Rhipsalis. In Species Plantarum, ed. 2, i. 668 (1762) he repeats the

osis from the Systema, but drops the reference to Sloane, citing instead
Jactus parasiticus imermis dc. Browne Jam. 238. In the Linnean
Herbarium there is a specimen from Browne named Cactus parasiticus by

he aga this has no flower, and is either Dendrophylax funalis, or a

afless species of Campylocentrum.

This species furnishes the best ‘“‘ vanilla beans” of commerce,

and is cultivated to some extent in Jamaica. It may conse-

quently occur here and there, in a naturalised state, producing

_ perfect fruit, as it has done in Hope Gardens without being

artificially pollinated, and on that account we have included it.

' Miller’s V. mewicana (Gard. Dict. ed. 8, 1768), as well as

Swartz’s V. aromatica (in Nov. Act. Upsal. vi. 66, 1799 & in

Schrad. Journ. ii. 208, t. 1, fig. 1b, 1799) was founded on Linnzus’s

20 ORCHIDS OF JAMAICA

Epidendrum Vanilla, and included the vanilla beans of commerce
and the ‘leaves and flowers of another species.

The pods of both V. pompona Schiede and V. planifolia are
used in commerce, and as V. pompona is much more widely
spread than V. planifolia, it is probable that its pods were
more common in early times before cultivation was resorted to.
V. pompona is not so much cultivated at present as V. planifolia,
as its pods are not nearly so valuable commercially.

Judging from the habitat given by Miller for the plant
cultivated by him, from the thickness of the pod (“scarce an
inch broad”), and from the shape of the leaves “oblongo-ovatis,”
it seems more probable that his plant was V. pompona rather
than V. planifolia. |

V. inodora Schiede has much the same distribution on the
mainland as V. pompona, and extends also to the West Indies.
The stem and leaves of this species may have been sent to
England as specimens of Vanilla, and certainly some of the
old drawings suggest V. inodora rather than V. pompona or
V. planifolia, e.g. Catesby’s plate (Nat. Hist. Carol., App. t. 7),
which is quoted by Miller as his V. mewicana. Miller also
states in his generic description that the lip “runs out into a
long point,” and this cannot apply to either V. pompona or V.
planifolia, but may well refer to V. inodora.|

dense terminal spike which is often elongate. Sepals subequal,

median concave sepal. Lip erect from the base of the column
which it embraces, produced below into a descending obtuse

Anther erect, shortly acuminate, cells contiguous, distinct ; pollinia
granular, pendulous from an oblong gland of the rostellum, which
is deeply 2-fid on the fall of the pollinia. Capsule oblong or

Species about 60, natives of the warmer regions of America
and Asia.

The name Erythrodes (Blume Bijdr. Flor, Ned. Ind. 410,
t. 72, 1825) must be adopted for this genus,—Physurus (L. C.
Rich. in Mém. Mus. Par. iv. 55, 1818) being a nomen nudum.
We cannot follow Schlechter (Schum. & Lauterb. Nachtr.
Fl. Deutsch. Siidsee, 87) in separating as Hrythrodes the Old
World species as a distinct genus from the species of the New
World. His distinction rests on the bilobed character of the
spur in the Old World species, which in our opinion is
insufficient. The habit of the species from both hemispheres is
similar, and the general structure of the flowers also closely
corresponds. In the West Indian species, E. plantaginea, the
spur sometimes shows an indication of lobing in a slight median
depression.

base, spreading. Petals equal to sepals or a little shorter, narrow.
Lip sessile, entire or lobed, with auricles embracing the column,
not extending as far as the sepals, but, including the auricles,
longer than the sepals. Column very short, terete, hollowed at
apex. Anther terminal, incumbent, two-celled. Pollinia 4, waxy,
ovoid. Capsule small, ovoid or turbinate.

Species about 140, widely distributed, but mainly in Central
America and Indo-Malaya. —

* Swartz adopted the name Malaxis from Solander and defined the
genus in Prodr. 119 eee including therein the two Jamaican species
M. spicata and M. lliflora. This name must therefore be retained for
these and for the other species nowincluded under Microstylis. The latter
name is cited by Bentham & Hooker (Gen. PI. iii. 494) as of Nuttall (Gen.
N. Amer. Pl. ii. 196), but Nuttall uses it only for a section of Malazis.
Microstylis was first used as a generic name by Lindley (Orch. Scelet. &
Gen. & Sp. Orch.).

* The lip is described and figured by Swartz as trilobed, but in all the
Jamaican specimens examined by us, including Swartz’s type, the lateral
lobes are not evident. Swartz describes his figure as the flower of
M. spicata or M. umbeliliflora, and in his description of the latter omits
the parts of the flower as being very similar to M. spicata. The drawing
agrees best with M. wmbelliflora, under which we have cited it. In his

Icon. ined. tt. 19 & 20, the flowers are represented as precisely similar, |

and we can only suggest that a flower of M. wmbelliflora has been drawn
for each plate.

Stem T-12 cm. 1., 1*5-2 mm. br., sometimes as short as 2 or 8 cm., or
as long as 15 cm. Sheaths striate, apex truncate, apiculate, generally
covering stem, scarious, soon decaying. Leaf lanceolate-oblong or ligu-
late, apex obtuse, sometimes minutely toothed, generally somewhat longer
than stem, 11 or 12 cm. 1., about 1-5 cm. br., sometimes as short as 7 cm.,

Flowers : the size of the flower varies considerably: in Swartz’s original
specimen the median sepal is 2:3 mm. 1., 1-4-1-5 mm. br., and the petal
*6 mm. 1, and br.; in Fl. Jam. 7537 the median sepal is 2°5 mm. 1. and br.,
and the petal -75 mm. br.; in Fl. Jam. 7835 the median sepal is 3 mm. L,
2°5 mm. br., and the petal 1 mm. br. Measurements of parts of the
flower from dried specimens are somewhat misleading. In specimens put
into spirit when collected (Fl. Jam.10,087) the median sepal is 3:75 mm. 1.,
3 mm. br., and the sepals are not distinctly keeled on back (petal
1°2 mm. br.); sepals from the dried specimen (moistened in hot water)
measure 3°5 mm. 1., 2°4 mm. br., and are obviously keeled. The flowers

. from the type specimen, and also from the Marquis of Blandford’s specimen

figured by Sowerby (J. Z. Smith, Hxot. Bot. t. 75), are much smaller, but
these are evidently not fully developed. Sepals pale green, 3-nerved, the
central nerve in the median sepal sometimes forming a dorsal mucro just
below apex, lateral nerves generally meeting the central nerve above in
lateral sepals, but not always in the median sepal, lateral shorter but as
broad or broader. Petals deep purple, sub-quadrangular, upper margin
subdeltoid-lunate. Lip deep purple, somewhat like petals but broader
above, upper surface semicircular with a narrowly elliptical median
depression, with the upper margin lunate. Colwmn deep purple.

_ Lindley says of P. wnivaginata, ‘very like the last” (P. gelida),
“but distinguished by the state of the sepals and form of the lip.”
_ Examination of the type specimens in Lindley’s herbarium and of other
_ available material leads to the conclusion that we are dealing with only
one species. The degree of union of the lateral sepals varies somewhat,
while the hairs to which Lindley refers in his description “ sepalis intus

} _ Ppilosis,” are present to a very slight extent in the type specimen; the form

of the lip is the same in both, the two median wing-like keels being present,
though Lindley says of wnivaginata, “ labello ecarinato.”

56 ORCHIDS OF JAMAICA

Neither at Kew nor the British Museum are there any specimens
named P. gelida, and Grisebach merely quotes Lindley’s description,
which was based on a cultivated plant obtained by Messrs. Loddiges from
Jamaica.

The figure in Xenia Orchidacea (vi. t. 267, II.) represents the flower
more widely open than obtains in any specimens we have seen.

60 ORCHIDS OF JAMAICA

Plant 24 in. high, with creeping rhizome. Secondary stem 1°5-4 cm.
1., slender, the lower half loosely sheathed. Leaf 1°5-8°3 cm. 1., 5-8 mm.
br., sessile, margined. Peduncles 3-5 mm. 1. Bracts about 1 mm. L,
sheathing, truncate, obtuse. Flowers greenish-yellow, striped violet inside
(fide Cogniaux), about 4 in.1. Sepals about 4 mm. 1., 3-nerved; median
narrow, triangular, acute, concave, 1°2 mm. br. ; lateral triangular, falcate,
slightly narrower. Petals2mm.1.,°5mm. br. Lip, lower portion some-
what broadly ovate above a short broad claw, indistinctly 3-lobed, middle
lobe narrow, oblong, blunt, about 2 mm.1.; lower portion about two-
thirds of whole length; margin papillose. Capsule obovoid, narrowly
3-keeled, 8-9 mm. 1.

Lindley included two plants in his description of P. Wilsonii—one from
Cuba (Wright, No. 668), and the other from Jamaica, collected by Wilson.
The two plants differ remarkably in the conformation of the lip, and
must be regarded as‘ distinct species. We retain the name P. Wilsonii
for the Jamaican plant, as Lindley’s description of the lip evidently
refers to it, and not to the Cuban plant, which we have described, in
Journ. Bot. xlvii. 129 (1909), under the name P. confwsa.' The lip only
of P. Wilsonit is represented in Pl. 9, f. 8. A portion of the plant
P. confusa is shown in f. 5, a petal in f. 6, and the lip in f. 7. .

Cogniaux’s description of Porto Rico and Guadeloupe specimens differs
somewhat from ours, e.g., the median sepal is oblong-subspathulate, obtuse,
the petals are narrowly ovate, 1°5-1°75 mm. 1., *75 mm. br., the peduncles
are 6-14 mm. l.

13. P. monophylla comb. nov. ; stem shorter than the leaf;
racemes, two or three together (only one flowering), with two
flowers, shorter than the leaf; leaf elliptical-lanceolate ; ovary
warty ; sepals pale-green, lateral united near base and somewhat
gibbous; petals lanceolate, acute——-P. emarginata Lindl. Fol.

covered for the most part by sheathing bracts. Leaf 3-4 cm.1.,1°2 cm. br.,
obtuse. Pedicels about one-third as long as sepals, rather swollen upwards.
Bract scarcely exceeding the pedicel, sheathing, with ovate acute mouth.
Sepals 7 or 8mm. l1., 1-nerved, slightly keeled, lanceolate, acute. Petals
minute, about one-third as long as sepals, whitish with a red central line,
1-nerved. Zip small, about as long as the petals, pink or deep purple,
lanceolate, parallel with the petals and enclosed by them, nearly plane,
slightly serrated at the margin, near the base above having two indistinct
tubercles. Colwmn shorter than the petals, straight, semicylindrical at the
base, above at the base of the anther expanding into a sort of hood
formed by the concave broadly winged and toothed margin, the base
deep purple. Ovary very short, purple.

obtuse. Column crimson; anther light-purplish. Capsules 5 mm. 1,
4 mm. br., obovoid, with 6 ridges.

The colour of the sepals varies with age; when the flower opens, it is a
transparent light yellow slightly shaded with crimson down the centre;
as the flower grows older the crimson shading extends almost to the edges
showing very little of the yellow. When the flower opens, the tips of both
lobes of the petals overlap, then they straighten, but in the old flower
converge again ; when the lobe-tips converge, the apex of the petal appears
distinctly acute, but when the petals are straight, the apex is not evident.

- Mus. Brit. labelled in Solander’s hand ‘“‘ Epidendrum patens fl. ind. occid.,

Barthol.” agrees with Swartz’s description. Swartz assigns the species to
Jamaica and the Carribean Islands and cites Fahlberg as the collector.
Samuel Fahlberg, a Swede, visited St. Bartholomew in 1785, The specimens
referred by Lindley to this species, belong to the section Amphiglottum,
characterised by a closely sheathed peduncle, and have flowers 14 in. across.

Limodorum floridum was founded by Salisbury on a specimen sent
‘from Jamaica by Wm. Shakespeare.” The original specimen is not
extant, but among Salisbury’s drawings and Mss in the Department
of Botany are comparative descriptions and sketches of parts of the
flower of this species and of L. verecundum ; the drawing of the lip of
L. floridum is reproduced in our plate. Brown followed Salisbury in
regarding the two species as distinct, but there are no specimens of Bletia
florida authenticated by him. In our opinion B. florida is identical with
the plant subsequently described by Hooker as B. Shepherdit.

42. EULOPHIA R. Br.

the column. Petals somewhat similar to the median sepal, but
a little broader and shorter. Lip attached at the apex of the
foot of the column, forming a gibbous sac or spur between the
lateral sepals, 3-lobed, lateral lobes embracing the column, the
median rounded, spreading, with curled margin. Column ereet,
produced at the base into a foot, semiterete, with acute scarcely
winged angles ; clinandrium oblique, entire. Anther terminal,
opercular, incumbent, obtusely conical, with a 2-lobed appendage,

AX 49. NEO-URBANIA Fawe. & Rendle.

Herb, on trees or procumbent on shady stony banks, with
long leafy branching stems, the lower internodes rooting.
Leaves alternate, narrow, with persistent tightly adpressed
sheathing stalks. Flowers stalked, rather small, few, clustered
in the axils of the leaves. Sepals nearly equal in length and
breadth, connivent, median free, lateral adnate to the foot of
the column, forming a chin under the lip. Petals similar to the
sepals. Lip 3-lobed, jointed to the foot of the column, and
incumbent on it, the lateral lobes above the base curved in
towards the column, the blade oval, recurved-spreading. Column
very short, erect, not winged, produced at the base into a long
foot ; clinandrium slightly concave, entire, the median line
raised, and ending in the slightly pointed rostellum; anther
terminal, opercular, incumbent, hooded, 2-celled; pollinia 4,
waxy, pyriform, equal, compressed laterally, collateral in pairs
in the cells, not appendiculate, free. Capsule long, oblong,
shortly beaked.

Differs from Ponera in its free simple pollinia and axillary
flowers; from Pleuranthium in the lip, which is free from and
‘attached to the foot of the column, and in the pollinia; from
Camaridium in habit, in character of the pollinia (absence of
gland and stipes), and in the connivent perianth.

O. altissimum Sw. is credited to Jamaica by Swartz (Prodr.
123 & Fl. Ind. Oce. 1481). We have seen no specimen nor any
other record of the species for Jamaica. Swartz’s citation may
have been due to the fact that Jacquin, in his first description of
the species (Epidendrum altissimum Pl. Ins. Carib. 30, 1760), cited
Sloane’s figure (Hist. Jam. i. t. 148, f. 1), which, as we have
seen, represents O. luridum. The species is known from Guade-
loupe, Dominica, Martinique, St. Vincent,. Mexico, Panama,
Colombia, British Guiana, and Surinam.

A very closely allied species, O. sphacelatum Lindl., from
Florida and Central America, has been grown under the name
of O. altissimum in the Jamaica Botanic Gardens, and a flower is
figured on Pl. 29, f..22-25, but there is no satisfactory evidence
that it is native in Jamaica.

pseudobulb, thin, simple or more rarely somewhat branched.
Racemes lax, with small tender flowers, distinctly stalked.
Bracts ‘about as long as the stalks or shorter, narrow, acute.
Sepals about equal, spreading, free or the lateral shortly connate
at the base. ‘Petals similar to the sepals or a little broader.

* We have retained the original spelling for this genus. Bentham and
Hooker f., Gen. Pl. iii. 564 (1883), on etymological grounds, wrote Leiochilus,
overlooking the fact that a genus of Rwbiacee established by Hooker in
an earlier volume of the same work, ii. 116 (1873), bears the same name.

59. DICHZA Lindl.

Kpiphytic herbs. Stems leafy, elongated, often pendulous,
covered with the leaf-sheaths and leaves. Leaves in two ranks,
somewhat membranous, spreading, short. Peduncles axillary,
solitary, each with one small flower, with two or three scarious
ample bracts, one above the other, near the base, the upper one
acute, the lower obtuse, and bracteoles generally two at apex
below the flower, the lower broadly roundish, apiculate, the
upper linear, sometimes wanting. Sepals subequal, free, spread-
ing, lateral, slightly oblique, forming at the base with the foot of
the column a scarcely prominent chin. Petals similar to the
sepals, but smaller. Lip fleshy, fixed to the base of the column,
sometimes with a short claw; blade sometimes broadening
upwards with angles produced sometimes into lobes or teeth,
concave, undivided. Column erect, semiterete, very stout, at
the base produced into a short or very short foot ; clinandrium
oblique, short, entire, rather broad. Anther terminal, opercular,
incumbent, very convex, imperfectly 2-celled ; pollinia 4, waxy,
ovoid, closely incumbent in pairs on themselves, without
appendage, affixed by a flat stipes, with a small gland. Cap-
sule ovoid or oblong, muricate or smooth, ribs only slightly
prominent.

Lindley included two species under his D. echinocarpa, viz. Limodorum.
pendulum Aubl. Guian. t. 322, and Hpidendrum echinocarpon Sw. Prodr.
124; in this he is followed by Cogniaux in Symb. Ant. iv. 182 (1903) and
in Fl. Bras. iii. pt. 6, 487, under the name D. pendula. Swartz described
the lip as entire, and the Jamaican specimens agree with this. Aublet’s
figure shows a trilobed lip, which accords better with Lindley’s description
of the lip as sagittate. Aublet’s species should therefore bear the name
D. pendula, while D. echinocarpa should be reserved for the Jamaican plant.

#61. HARRISELLA Fawe. & Rendle.
Epiphytic herbs, stemless and leafiless; roots clustered.

Flowers minute, in two ranks, in lax few-flowered radical racemes, _
jointed on a short pedicel which is swollen above. Bracts small,

persistent. Sepals free, subequal, erect, slightly spreading above:.

hooded over it. Column very short, without a foot; anther
terminal, opercular, incumbent, rather flat, indistinctly 2-celled ;
pollinia 2, globose, waxy, with short filiform stalks. Capsule
small, shortly ellipsoidal, dehiscing from the apex by six valves
which are alternately broad and narrow.

Species, only one known, native of Jamaica and Cuba.

The genus is very near to Campylocentrwm, in which it has been
included, but differs in the inflorescence, the lip, the form of the anther,
and the form and dehiscence of the capsule.

It is dedicated to Mr. William Harris, F.L.S., Superintendent of

Public Gardens, Jamaica, and an indefatigable collector, who has added
much to our knowledge of the Jamaican Flora.
