To the botanist few orders of plants stand more in need of
illustration from living specimens than Orchids. This is chiefly
due to the highly differentiated form either of the perianth or of
the essential organs, and, in the latter case to the additional fact
that these are usually more or less fleshy in their texture, and
that dried specimens of these organs do not recover their shape
after soaking or boiling. Hence it is often difficult both to
describe them satisfactorily, and for the student to identify
specimens from such descriptions. This is especially the case in
the tribe Ophrydex, so largely represented in South Africa, and
it is so in a still greater degree (because the column.is usually
most highly complicated) in its sub-tribe Coryciez of which three
out of its four genera are exclusively confined to South Africa.
It is to endeavour to meet this need that this work has been
undertaken. An exception has been made in the case of a few
species which have been drawn from dried specimens, where
there was no hope of obtaining living plants within a reasonable
time, and where (in most cases) flowers freshly preserved in
spirits or glycerine have been sent to me by kind correspondents.

To the field-botanists, students, and lovers of nature in South
Africa, a class which, it is pleasant to know, is now yearly
increasing, I trust the book will be of service, and prove a
stimulus to fresh investigation and discovery.. A country life
affords the greatest opportunities for the close observation of
nature, and more than one farmer has been amongst its friends

vi PREFACE.

and correspondents who have enthusiastically and generously
aided me by procuring and sending living specimens from distant
parts of the country.

I must especially record my obligations to the great national
establishment at Kew, whose authorities have at all times afforded
me every assistance; to Prof. Outver, F.R.S., who has seen, and
revised for me the proof sheets of the plates for the press during
my residence at the Cape; also, at the Cape, to Prof. MacOwan,
Prof. Bopxtn, Prof. Gururiz, and Dr. Maruotu, of Cape Town;
to Mr. H. G. Fuanaaean, of Komgha; to Messrs. EH. Ganpin and
W. Cutver, of Barberton; to Dr. 8. ScHornnanp, and Mr. J.
Guass, of Grahamstown; to Mr. T. R. Sim, Curator of the Botanic
Gardens, King William’s Town; and to Mr. J. Mepiey Woop,
Curator of the Botanic Gardens, Durban, Natal. Last, but not
least, to Mr. Rupotr ScHuEecuTER, an enthusiastic and diligent
botanist and collector, who has lately arrived from Germany, and
is at present engaged in an extensive tour throughout South
Africa. This gentleman has already made considerable additions
to our knowledge of the Cape Flora, and has been good enough
to furnish me with many living specimens, and to aid me with
his observations and advice upon several critical species.

NOTE.

TuE measurements used throughout in this book are those of what
is known as the metrical system, of which the unit is the meter, which

_ is equal to 89-37079 inches in English. This is now largely employed

by the scientific writers of every nation, and I regard it as a duty to
promote by all possible means the use of the system, which must
assuredly, sooner or later, be universally adopted. To facilitate its use
by those who may not be familiar with it I have added the following
scale showing on the upper line the metrical, and on the lower the
English measurements :—

0 ! ? 2 3 4 s 6 Ee 8 2 10

MILLIMETRES.

Lines.

Roughly speaking, the
Meter is equal to 8 ft. 3 in. and 3-8ths, or 1 yard and 1-10th.

Decimeter _,, 4 inches.
Centimeter ,, about four-tenths of an inch.
Millimeter ,, about one-twenty-fifth of an inch.

Where two measurements are given, as for example ‘‘stem 15-35
em. high,” or ‘leaves 8-7 cm. long,” it is to be understood that these
are the extremes of size seen by the writer, and that the average length
is probably nearly midway between the two.

The abbreviation met. is used for meter; cm., for centimeter; mill.,
for millimeter.

ADDITIONS AND CORRECTIONS TO PARTS I. AND IL.

)

Since the publication of Part I. of this work I have seen
reason to change my views in regard to certain plants therein
figured, and I take this opportunity of stating them, and
also of making corrections of some errors which had escaped
attention :—

Puate 4. [Eulophia micrantha, Lindley.| In the Journal of Botany,
vol. Xxxii, p. 330 (1894), Mr. Schlechter and myself gave our reasons
for removing this plant to Acrolophia, under the name A. micrantha,
Schlechter d& Bolus.

Puate 5. [Eulophia cochlearis, Lindley.] Similarly removed to
Acrolophia cochlearis, Schlechter d Bolus.

Puates 6, 7, 8,9, 10. In the heading of these plates in the third
line, in place of the words Sub-tribe Cymbidieae, read Sub-tribe
Sarcantheae.

Puate 17. [Habenaria Galpini, Bolus.) Further consideration of
numerous forms of H. tetrapetala, Reichenbach fil., shows the latter to
be an extremely variable species, and H. Galpini can only be regarded
as a form of it in which the petals are bipartite.

Puate 26. [Pachites Bodkini, Bolus.] In the plate the numbers
to the analytical figures 8 and 4 have been accidentally transposed,
and should be corrected with the pen.

Prats 33. [Disa torta, Swartz.] I now think that the form of lip,
which appears to be constant, and which there is nothing else in Disa
to resemble, together with the peculiar bent wiry stem in every species
but one, make it desirable to maintain the genus Schizodium as
established by Lindley. The present plant should therefore be re-
garded as Schizodium arcuatum, Lindley.

Puate 84. [Disa clavigera, Bolus.] For the reasons given above,
and because Lindley’s Schizodiwm clavigerum appears to be merely a
small-flowered form of his S. rigidum, I refer this plate to the latter
species.

Prats 49. [Pterygodium venosum, Lindley.] For this read: Cera-
tandra venosa, Schlechter, in Engl. Bot. Jahrb. ined.—Mr. Schlechter
has informed me of his intention to remove this plant to the latter
genus, to which it more properly belongs.

A small glabrous herb. Pseudo-bulb covered by the soil, ovate,
whitish, 2°5-4 cm. long; leaves usually 2, lying flat on the
ground, ovate subacute thick leathery, smooth above, 2°5-6 cm.
long (luxuriant plants sometimes show a smaller third, and even
fourth, leaf) ; scape erect rigid angulate many-flowered (10-30),
2-6 cm. long; flowers small crowded spreading, bracts lanceolate
acuminate, shorter than the ovaries; side sepals oblong sub-
falcate, 4 mill. long, odd sepal posticous oblong longer, margins
revolute ; petals linear, margins revolute, 6 mill. long; lip tri-

lobed, somewhat saddle-shaped, fleshy arched, half as long as the

larger oblong subretuse deflexed ; column oblong-cuneate curved,
without wings, shorter than the lip; capsule cylindrical, together
with the pedicel about 1°5 em. long.

Described from numerous living specimens. Colour of the lip
bright dark green, the remaining parts of the flower greenish
yellow. The species appears to be endemic ; a supposed identi-
fication with specimens (in fruit only) collected by Mann on the
Cameroon Mt., being extremely doubtful. It is somewhat
frequent on the Cape Peninsula, but I have never seen many
plants together excepting on the top of the hills just behind
Simon’s Town.

Plate 3. The plant with narrower leaves drawn from specimens
received from Mr. W. Culver, Barberton; that with broader leaves
from a plant cultivated at the Royal Gardens, Kew, said to have come
from Pondoland. Fig. 1, flower; 2, ditto, viewed from behind,—both
magnified about 6 diameters; 5, 6, column; 7, pollinia,—all the
latter variously magnified, and all taken from the narrow-leaved
specimens from the Trans- Vaal.

Stems aggregated creeping cylindrical elongate, internodes
2-8 cm. long; pseudo-bulbs ovate or pear-shaped, 4—7-angled,
8-4°5 em. long; leaves 2, elliptical or oblong, acute or emar-
ginate, 1-nerved, leathery, 5-7 cm. long; scape proceeding from

the stem near the base of the pseudo-bulb, leafless erect sub-
faleate, 8-15 cm. long, rachis dilated and flat in the upper part,
4-30-flowered, the flowers racemose upon each face, bracts
deltoid; side sepals ovate-lanceolate faleate acute, concave at
base, scabrid on the upper surface, about 6 mill. long; odd sepal
linear sub-obtuse, nearly twice as long as the lateral; petals
linear falcately spreading or reflexed, a little shorter than the
side sepals ; lip fleshy, square thick and keeled at the base, then
suddenly contracted into a sub-obtuse tooth-like pendulous point,
the whole scarcely 2°5 mill. long; column short, widely winged,
the wings terminating in a short tooth on either side at the
summit; capsule oblong, 1-1°5 cm. long.

Described from several living and dried specimens. Colour of
the flowers dull red-purple, the petals usually paler or reddish-
orange. From a drawing which I have seen by the late Mr.
John Sanderson, the colour is probably somewhat variable. I
have examined the specimens in the Kew herbarium marked
Megaclinium Sandersoni, and the type of M. scaberulum, and
compared them with Mr. Culver’s specimens from Barberton
here described, and incline to regard them all as forms of one
variable species. This plant is interesting to South African
students as being the only one of a somewhat large genus which
straggles beyond the tropic so far south. The section Megacli-
nium to which our plant belongs is held by some botanists as a
good genus; the difference from Bulbophyllum consists almost
exclusively in the flattened and enlarged rachis of the inflores-
cence. The remaining members of this section are all, with one
exception, inhabitants of tropical Africa. The genus Bulbo-
phyllum as a whole, is, however, spread over the tropical regions
throughout the globe.

Plate 4. The small figure to the left represents the whole plant
reduced in size; the single leaf and inflorescence of the natural size.
Fig. 1, flower; 2, one of the side sepals; 3, odd sepal; 4, one of the
petals; 5, 6, lip from different flowers,—all the foregoing magnified 4
diameters ; 7, column, front view; 8, ditto, side view; 9, 10, pollina-
rium; 11, ditto, the pollinia removed showing the spirally-twisted
elastic threads by which they are attached to the stipes,—all the latter
variously magnified.

Stem erect, leafy at base, paniculately branched above the
middle, 80-75 cm. long; leaves 4-9, ensiform equitant rigid,
minutely serrulate, erect-spreading, 15-25 cm. long, passing into
bracts; flowers loosely racemose-paniculate along the branches,
spreading, at length deflexed; bracts lanceolate acuminate,
shorter than the ovaries; sepals and petals nearly alike, oblong
or ovate-oblong, obtusely acute, 4-6 mill. long; lip posticous
larger sub-galeate or spoon-shaped, obovate in outline, cuneate

at base, margin irregularly toothed and crisped, constricted on
the back just above the spur, furnished within with four rows
of filiform papille, externally minutely warty, spur short ovate
inflated ; column short and thick, hollowed at the base.

Described from several living and dried specimens. Colour of
the sepals tawny brown, petals yellowish-brown, lip cream-colour
with brown markings, sometimes (or always?) with a deep red
3-lobed patch on the inner surface near the base. The limb of
the lip resembles the bowl of a spoon, and is only slightly
spreading, not erect; this, and the constriction at its base,
forming a kind of inset or cross-furrow, viewed from the outside,
serves to distinguish it from EF. cochlearis ; but the distinction is
not easily seen in dried specimens. This species appears to be
almost exclusively eastern, as EH. cochlearis is western, in its
distribution. The flowers are the smallest amongst South-
African Eulophie.

Described from numerous living and dried specimens. Colour
of the flowers as in the preceding species, but the lip is destitute
of the large red spot seen in that. The two species are closely
allied and difficult to distinguish in the dried state; yet the
difference in the lip is well-marked and would be striking in a
larger flower. It may be added that the flower of this species,
and especially the lip, is usually a little larger than in LZ.
micrantha. I have seen no intermediate forms,

Described from several dried specimens, and also from some

me by Mrs. J. R. Saunders of Natal. The flowers are white.
The figure of the whole plant in the plate is from a drawing by
the late Mr. John Sanderson of Natal; the analyses are drawn
from my own dissection. Mrs. Saunders’ specimens are much
smaller than those of Gueinzius and Meller, and only a dissection
of the flowers enabled me to feel assured that the latter simply
represent a more luxuriant growth. In habit and general
appearance this plant much resembles an Angrecum from
Madagascar described by Lindley as Microcoelia exilis. It is even
more strikingly like A. Fasciola, Lindley, from Surinam, and
A. tenue, Lindley, from Paré,—the latter of which has flowers
_ still smaller than those of this species, and all are amongst the
most minutely-flowered of known orchids.

figure was drawn and printed that I found from fresher specimens that
the sepals and petals in the plant drawn had become withered and in-
curved, and that their natural position is spreading outward.]

An epiphytical herb ; stem slender creeping, emitting roots at
intervals throughout its length, 5-15 cm. long, 2-3 mill. in dia-
meter; leaves distichous strap-shaped, unequally emarginate,
leathery, 5-10 cm. long; racemes flexuous, shorter than the

leaves, loosely 5-8-fl., bracts minute, flowers, with the ovaries,
5-8 mill. long; side sepals lanceolate-oblong sub-obtuse concave ;
odd sepal ovate, very obtuse; petals broadly ovate or suborbicular,
a little shorter than the sepals; limb of the lip transversely
oblong, obscurely 3-lobed, intermediate lobe obtusely acute, a
little longer than the sepals and petals; spur cylindrical, with a
wide mouth, obtuse, incurved or hooked, 4-5 mill. long; anther
rounded, very obtuse; pollinia 2, distant, nearly hemispherical,
each upon a linear flat incurved stipes lying on either margin
of the rostellum; glands 2, ovate, distant; rostellum beak-like
cuneate-oblong, the apex bent down into the mouth of the spur.

Described from several dried specimens and flowers preserved
in glycerine. Flowers white or cream-coloured. This little
species seems very well marked by its laxly few-flowered raceme,
and the very much incurved blunt spur, large for the size of its
small flower. Reichenbach placed the species in Aeranthus, and
Bentham in Mystacidium. According to the definition of the
latter author, the only constant difference between the two
genera (Angrecum and Mystacidium) is that the stipes or
stipites of the pollinia are flat in the first and filiform in the
second. LHven if this were to be regarded as a good character,
the stipes in the present plant appears to be distinctly flat.
Pfitzer, also, in Die Natiirliche Pflanzenfamilien (vol. ii, pt. 6,
p- 208) maintains Mystacidium, giving the chief distinction
as follows :

Pollinia on a single common stipes . . Angraecum
» on 2 stipes, quite distinct or
united only by the glands . Mystacidium
This character appears to me of insufficient weight, and separates
species otherwise very closely allied. Hooker in Bot. Mag. tt.
7161, 7204, has described and figured two Angrecums, the one
with two widely separated stipes and glands, the other with the
pollinia on two very short stipes and a single gland,—thus
attributing no importance to this character. In the genera Disa
and Satyrium, the latter of which especially, is very natural and
closely defined, while the usual character is two glands, instances
occur of species with a single gland, which few botanists would
separate on that account. I think therefore upon the whole that
Mystacidium cannot be maintained as distinct from Angrecum.

A small epiphytical herb. Stem short, scarcely 1 cm. long,
with many long filiform roots; leaves 2-4, distichous, obliquely
lanceolate, spreading or falcate-recurved, obtusely acute, leathery
thick and fleshy, 2-2°4 cm. long; spikes several, rising from the
axils of fallen leaves, 3-5 cm. long, many-fl. (8-15-f1.), bracts
membranous, the lower reduced to shorter sub-erect brown
empty sheaths, the floral larger spreading ovate acuminate
white, enwrapping the flower; flowers sessile, including the
ovary about 6 mill. long, perianth spreading, its segments about

equally long; side sepals narrow lanceolate acuminate, obliquely
and suddenly bowed or arched at the base, thence nearly
straight; odd sepal broader, acute; petals lanceolate subundulate;
lip ovate-lanceolate, very acuminate, spur cylindrical obtuse,
slightly incurved, a third part shorter than the limb; column
oblong, narrowed above ; anther somewhat square, bilobed;
rostellum subulate, very acuminate, bent downward and then
sharply up-curved or hooked, perforate near the apex (for the
reception of the single ? gland ?); pollinia elliptical [stipes and
gland not seen]; capsule elliptical, ribbed, about 3°5 mill. long.

Described from 3 dried specimens as above; the flowers are
evidently white, their small size in comparison with the large
membranous bracts, seems to distinguish the species very well;
there is nothing resembling it in the Kew herbarium. All the
flowers I examined had lost the stipes and gland of the polli-
narium; and I only found one pollinium which had lodged in
the cavity of the stigma ; but linfer from the perforate rostellum
(which I have not observed in any other species) that there is
probably only one gland. I have dedicated this highly inter-
esting little species to its discoverer, Mrs. Charles Saunders, who
is a diligent observer of Nature in the woods of Zululand, and
has contributed several novelties to botanical science.

gined by a narrow membrane; capsule oblong, 9 mill. long.

Described from several excellent dried specimens of Wood, the
flowers analysed and drawn from specimens freshly preserved in glyce-
rine. Colour of the flowers according to Wood ‘ greenish-yellow,”
(‘brownish ’’ according to Barter). I have hesitated for some time as
to the genus of this plant. When it was first sent to Kew by Mr. Wood
it was named Spiranthes by Mr. N. E. Brown, who considered that
Platylepis should be entirely removed to that genus. In looking at the
fine figure of Neottia speciosa in Jacquin’s Icones Plant. Rar. t. 600, I
was immediately struck by the strong resemblance in general type of
the column of that plant to the one now treated of, and I think it
probable that, dissimilar as they are in other respects, these two species
must find their ultimate place in the same genus. The tubular
character of the column (a tube quite independent of, and included
within, the partial tube formed by its union with the lip) in both is
very remarkable; and this appears to me to be of more importance
than the relative length of that organ, and also more than differences
in the perianth, or in the habit. Richard, and Lindley following him,
removed Neottia speciosa to Stenorhynchus as S. speciosus, Lindley
expressly stating that after much consideration he had determined
upon regarding it as distinct from Spiranthes. Bentham, however
(Gen. Plant. iii, p. 596) included Stenorhynchus in Spiranthes as a
section of the latter genus. Pfitzer (Natuerliche Pflanzenfamilien ii, 6,
pp. 112, 115) maintains both Stenorhynchus and Platylepis, though in
different subtribes of his Neottiinez, including S. speciosus, Rich. in the
former, and, apparently, our present plant in the latter. It appears to
me that both of these differ too widely from the European species of
Spiranthes to be joined with them generically. No doubt the proper
location and arrangement of many of these smaller genera can only be
effected after a careful dissection of all of them, with ample material,
when quite possibly our present plant may be fitly joined with Steno-
rhynchus, or even with Goodyera. Meantime, to avoid a new name
which may probably have to be altered, I have thought it best to adopt
Reichenbach’s last published name. My friend Mr. C. B. Clarke, of
Kew, who was also kind enough to look into this matter for me, points
out that the nearest ally of the present species is Platylepts goodyeroides,

Plate 12. Fig. 1, flower and bract; 2, one of the sepals; 3, one
of the petals ; 4, lip, partly flattened out,—all the foregoing magnified
2 diameters; 5, column, front view; 6, ditto, side view; 7, ditto, the

view of the anther; 9, diagrammatic section of the lip, showing the
median callus or crest; 10, section of the anther; 11, pollen
granules,—all the latter variously magnified.

A glabrous erect herb, 15-28 cm. high; tuber spherical or
ovoid ; flowering stem simple leafless, furnished with 2-8 short
distant sheaths ; leaf solitary from a separate bud of the same
tuber, appearing after the flowers are withered, petiolate ovate
acute plicate, including the petiole of 2°5 cm. long about 10 cm.
in length; raceme loosely 3-4 flowered, flowers spreading, bracts
narrow linear membranous, shorter than the flowers; sepals and

petals similar, nearly equal in length, lanceolate acuminate
spreading veined, about 1°6 cm. long, or the petals a little shorter
and broader ; lip inferior, nearly as long as the petals, cuneate-
obovate veined, traversed by three raised ridges, 3-lobed towards
the apex, the side lobes shorter, rounded or acute, ascending, the
intermediate lobe longer subulate acute deflexed; foot of the
column elongated, shorter than the lip; anther incumbent affixed
to the apex of the column by a hinge-like joint; pollinia — ?
(only seen in the numerous separated roundish granules) ; cap-
sule ovoid pendulous, 1°2 cm. long.

Described and drawn from several dried specimens, with
separately and carefully dried flowers and notes of colour from
the collector. Colour of the sepals and petals pale greenish
yellow with brownish green veins; the lip veined with purple.
The original description was based upon a plant in Sonder’s her-
barium supposed to have been found in the Magaliesbergen,
whence we may infer that it was most probably collected by
Zeyher, during the journey made by him to the Trans-Vaal with
Burke (a collector sent out by the Earl of Derby) in 1841. I have
not seen any authenticated specimen, but as Mr. Culver’s excel-
lent specimens agree very well with Reichenbach’s brief des-
cription, as far as the latter goes, and as it is the only Pogonia
known from South Africa, I have very little doubt as to their
identity. Mr. Culver has been very successful in collecting the
Orchids of that region; he is the only one who has found this
species since Zeyher, and I am indebted to him for several other
rare and novel species.

An erect slender herb, 7-15 cm. high; tubers globose or ovoid,
matted with fine hairs; leaves 2, radical, the lower broadly ovate
or sub-rotund, the upper smaller ovate, both acute glabrous
ciliolate; scape pilose with rather short brown hairs which are
thinly placed above but more thickly below, 4-9-flowered, flowers
minute, somewhat erect, turned in every direction ; bract ovate
cuspidate pilose, very much shorter than the ovary; sepals
oblong obtuse glabrous, shorter than the petals; petals ovate-
oblong, obtusely pointed, shorter than the lip; lip nearly
orbicular in outline, or ‘‘ cuneate” (Sonder), cleft into five nearly
equal segments of which the intermediate one is spathulate, the

upper pair bilobed, all somewhat obtuse, with a short straight
conical spur at base; ovary glabrous straight, or “twisted”
(Sonder).

Described from the living specimens first above mentioned.
The petals are pure white. The glabrous leaves are somewhat
unusual in the genus. The flowers apparently vary in size;
those I saw in a living state were about 5 mill. long. Sonder,
whose descriptions I have always found very trustworthy, says
that the petals are three times as long as the sepals, which I did
not find in my specimens. His description was based on the
specimens of Mundt and Zeyher. About Cape Town the species
appears to be somewhat rare.

Tubers ovate glabrous; leaves two, glabrous or thinly pilose, ciliolate,
withered before flowering, the lower radical lying flat on the ground, ovate
or orbicular, fleshy veined, about 1 cm. long, the upper cauline very small
lanceolate; scape erect very slender, 15-25 cm. long, patently pilose below,
becoming glabrous above; spike many-fl. (8-17-fi.), generally secund or
nearly so, 4-6 cm. long; bracts ovate acute erect, pilose on the margin and
apex, shorter than or equalling the ovary; flowers glabrous, 4 mill. long; odd
sepal ovate, side sepals obliquely ovate-lanceolate obtuse; petals narrow
lanceolate obtuse, twice as long as the sepals; lip undivided lanceolate, as
long as the petals, widened and concave at the base, spur much shorter than
the sepals; anther oblong sub-erect, cells parallel; caudicles of the pollinia
terminating in a single gland ; ovary oblong or ovate, twisted.

Described from numerous living specimens kindly sent by Mr. Glass from
near Grahamstown. These were the first I had seen; yet by a curious
coincidence Mr. R. Schlechter found, during the same week a single specimen
on Table Mt., near Cape Town, where it had never previously been recorded.
He also found on the same mountain a single plant of the typical form.
The variety here described does not appear to differ from the typical form as
described by Lindley, (founded on Burchell's 6738 from the Riversdale dis-
trict, 17th Nov., 1814) excepting in the lip which is entire, while Lindley
found it with a basal lobe on either side. But Mr. Schlechter subsequently
found also at Riversdale plants having a lip intermediate in form between
the two. Though Ihave not examined living specimens of the typical form I
can hardly doubt that Sonder’s species isa mere variety. I have not seen an
authentic specimen of the latter, but our plants agree well with his description.
The sepals are green with a pale margin, the petals deep ochraceous yellow,

bracts ovate acuminate shorter than the ovary; flowers glabrous,
about 8 mill. long; odd sepal nearly orbicular, obtusely acute, side
sepals broadly ovate; petals linear, widened at the base, obtuse, a
little longer than the sepals; lip ovate in outline, concave, 3-fid, the
segments linear obtuse, a little longer than the petals, spur conical
straight, shorter than the sepals; column somewhat conical, obtuse;
caudicles of the pollinia terminating in a single gland.

Described from numerous living and dried specimens. Colour of
the petals and lip ochraceous yellow. The species is well distinguished
by its particularly long and soft indument; and though dried specimens
may sometimes resemble some forms of H. squamulosa, Lindley, (Bolus,
Orchids of the Cape Peninsula, t. 28) the latter may always be known
by the 5- or 7-fid lip and the slenderer curved spur. It appears to be
a widely distributed plant, and about Cape Town, at least, is frequently
to be seen every year,

Described from several living and dried specimens. Colour of
the flowers pale green, the anther greenish-yellow. A _ well-
marked though variable species, one of its extreme forms being
that which I formerly described as H. Tysoni, but which, after
seeing and dissecting a larger number of specimens, I now
believe should be regarded asa variety merely. The fine closely-
set segments of the petals and lip give the spike a mossy
appearance, or, as was suggested by another observer, the look
of a number of those green web-less spiders which await their
prey at the bottom of flowers.

sepals ovate concave acute, about 7 mill. long; petals lanceolate
acute incurved, 4-5 mill. long; lip about as long as the sepals,
rough with minute shining papille, obovate in outline, deeply
3-fid, the segments oblong sub-equal or the intermediate a little
broader, spur cylindrical or somewhat inflated, compressed
dorsally, straight, about as long as the limb; ovary cylindrical
straight, not twisted, more or less exceeding in length the spur.

Described from two living specimens received from Mr. Sim,
from the Perie Forest, and from numerous dried specimens.
The colour of the flowers was bright yellow, the lip a deeper
yellow, petals pale but not white. Sonder, however, describes
the flowers as white, and Baur says “‘ flowers beautiful white, lip
golden yellow with small dark dots.” I have never seen a type
specimen of Ecklon and Zeyhevr’s, but the plants I have examined
agree well with the description of Sonder, whom I have always
found carefully accurate. I suppose this to be a very variable
species. Tyson’s and Scully’s specimens most resemble the
plant I have drawn. Wood’s and Sanderson’s are taller and
slenderer in proportion, with narrower and more distant leaves,
but there is hardly any difference in the flowers. S. Bulbinella,
mihi, has a denser spike of smaller flowers with the lip less
divided, and a proportionately much smaller spur. Of S. Gerrardi,
mihi, (Brachycorythis Gerrardi, Reichenbach fil.) I have seen no
authenticated specimens.

Stem a span or more high, erect, with about two inflated
sheaths; leaves 2, radical, the lower ovate, lying close to the
ground, about 7°5 cm. long, (the upper damaged in the
only specimen seen); spike somewhat loosely several-flowered,
bracts lanceolate, the lower spreading, the upper ascending,
mostly exceeding the flowers; sepals oblong subacute, about
7 mill. long, the side ones oblique or subfalcate, the middle one
straight ; petals strap-shaped acute, the margins minutely and

irregularly notched, narrower than the sepals and almost equally
long; lip galeate clobose-inflated, mouth roundish, dorsal ridge
sharply keeled, free apex acuminate reflexed, spurs filiform
pendulous about as long as the ovary; stalk or foot of the column
twice as long as the rostellum; rostellum triangular or broadly
tongue-shaped, arched and projecting forward, emarginate in
front, the glands situate very near each other on either side the
notch; anther pushed up horizontally and projecting beyond the
rostellum, apex of the connective free acuminate bent forward
under the rostellum ; stigmatiferous lobe bipartite, the segments
subulate erect, somewhat divaricate towards the apex, much
shorter than the rostellum ; ovary prominently ribbed.

Described from a single living specimen, collected as above.
Colour of stem and bracts brownish and pale red, flowers from
pale pink to white, spurs and nerves of the galea red. This is
so remarkable and distinct a species that I have not hesitated to
describe it from a single, and injured, specimen. The injury,
however, was in the middle of the spike, and, it is clear, had
nothing whatever to do with the peculiar structure of the column.
This organ resembles in some degree that of S. bicallosum, Thun-
berg, (Bolus, Orchids of the Cape Peninsula, t. 31) while both are,
in this respect, very different from that of any other Satyrium
known. In every other character this differs greatly from
S. bicallosum, and I doubt very much if it is a natural hybrid.
The specimen found had the upper portion of the spike injured,
and its development no doubt arrested; in its normal condition
it would probably be much longer than is shown in the figure.

Stem stout erect straight, 25-88 cm. high, closely covered with

orbicular or ovate, leathery or somewhat fleshy, veined flat and
appressed to the ground, 7-9 cm. long; spike somewhat short,
loosely or densely 8-12-fl., bracts oblong acute concave reflexed,
longer than the flowers; side sepals oblong, the odd sepal
narrower, all entire very obtuse and recurved, including the
deeply connate portion at base 1°4-1°6 cm. long; petals oblong-
spathulate obtuse, crisped and lacerate except near the apex,

margins incurved, a little longer than the sepals; lip galeate,
the limb nearly hemispherical, free apex large obtuse crisped,
produced at base into two conical sacs of about 2 mill. long;
rostellum rhomboidal, sharply tridentate with two recesses on
the front edge for the reception of the caudicles, gland only one,
nearly square, lying upon the rostellum; stigmatiferous lobe
semi-orbicular somewhat concave, cushioned; ovary 6-ribbed, of
which 5 are sharply ridged or almost winged.

Described from several living and dried specimens. The
flowers are rosy with darker carmine tints on the tips of the
sepals and petals. In habit and colour of the flowers this
resembles S. erectum, Swartz; in the shape and setting of the
flowers S. membranaceum, Swartz ; but its peculiar short conical
sacs, its single gland, and its almost winged ovary at once
distinguish it from these and from any other species. Lindley,
adhering literally to an artificial distinction, placed the species
in his group Saccate. But with none of the members of that
group has it any other alliance than in its abbreviated spurs,
while in other respects it differs widely from them, and I think
will be more naturally placed, as an exceptional species, in the
spurred group.

much interest ; though the occurrence of such a smell is not un-
known in Orchids (notably shown in Bulbophyllum Beccari,
Reichenbach f., vide Bot. Mag., t. 6567) yet it is somewhat
uncommon. There were no Stapeliz to be seen in the immediate
vicinity, and indeed I do not remember to have noticed any near
Ceres. The species is also structurally an interesting one. In
no other is the consolidation of the sepals and petals carried
nearly so far. Lindley, who missed seeing the petals in the
dried specimens, where they would easily escape detection, made
a new genus (Aviceps) of the plant. But Thunberg’s full
description first made in 1807 was perfectly accurate as I pointed
out in 1882 (Journ. of Linn. Soc. (Botany) vol. xix, p. 287), and
even before this Bentham had considered that the plant could
not be separated from Satyrium (ib., vol. xviii, p. 357).

A slender glabrous herb, scarcely a span high; stem erect
few-leaved ; radical leaves none, cauline about 5, linear acumin-
ate, with a broad membranous sheathing base, erect, the lowest
about 3 cm. long, the upper gradually smaller; raceme short,
loosely 5-fl., bracts leaf-like lanceolate, as long as the ovaries ;
sepals lanceolate acuminate 1-nerved erect-spreading, 1-3 cm.
long; petals acute, margins slightly incurved, prominently
1-nerved beneath, 1 cm. long; lip as long as the petals, erect,
8-lobed, side segments short oblong obtuse, the intermediate lobe
lanceolate much longer, furnished at base on the under surface
with a cluster of minute yellow tubercles; cells of the anther
curved, approximate at base only, glands of the pollinia capping
the arms of the rostellum; rostellum horse-shoe-shaped, with
erect arms (appendages) ; stigma horse-shoe-shaped, cushion-
like; ovary cylindrical.

Described from a single living plant. Colour of the flower
pale purple, suffused with darker purple on the side-lobes of the
lip; anther dark-brown; stem, bracts and leaves yellowish. The
discovery of this plant, and the subsequent re-discovery of the
very rare P. appressa, Lindley (due to the enthusiastic and
successful botanist and collector, Mr. R. Schlechter of Berlin)
have thrown light upon the generic characters of this interesting
genus, which has hitherto been very imperfectly understood.
The genus was established by Lindley in 1835 upon a single
almost deflorate specimen collected by Burchell in 1815. Ben-
tham (Gen. Plant. iii, pp. 629, 680) admitted the difficulty of
understanding its structure from the material available; but,
having had the advantage of seeing and drawing living specimens
of both species, I think they should be regarded as congeneric in
spite of some curious differences in the column (which exhibits
a singular affinity with that of Satyrium rhynchanthum, mihi,
Orchids of the Cape Peninsula, t. 25,—a plant in other respects
very different). By a remarkable coincidence while Burchell
found, as he carefully noted in his MSS. catalogue, only one
plant of P. appressa, Prof. Bodkin could find only one solitary
specimen of this species, and further search in the same and in
succeeding seasons has hitherto proved unavailing. Dr. Krauss,
however, found P. appressa once again 24 years after Burchell ;
and since then for upwards of fifty years, so far as is known, it
was not gathered, though others (and I myself) have searched
for it in the original locality. Mr. Schlechter, however, has
very recently found two specimens on the Langebergen near
Zuurbraak in the Swellendam district ; and I hope to publish a
drawing of the plant in the next part of this work,

An erect glabrous herb, 8-20 cm. high; stem straight leafy ;
leaves 4-5, mostly withered at the flowering period, the lowest
linear-oblong acute, the succeeding linear acuminate erect-
spreading, 2-5 cm. long, passing into erect leaf-like bracts; spike
ovate or cylindrical, 3-7 em. long, several- or many-flowered ;
bracts erect incurved, about as long as the flowers; flowers
somewhat nodding, together with the ovary about 2 cm. long;
side sepals oblong obtuse defiexed; odd sepal galeate obovate
retuse, bent downward, spur filiform curved, a little longer than
the limb, or than the ovary; petals subfleshy, large in proportion
to the galea, about as long as the side sepals, obliquely oblong

bilobed, the lobes equal rounded and very obtuse; lip linear
obtuse shorter than the sepals or petals; rostellum erect, with a
fold on either side turned back externally upon itself.

Described from numerous living specimens. Colour of the
sepals dingy pale yellow, usually with reddish tints at the tips of
the side sepals and over the whole back of the galea, but some-
times entirely free from red; petals and lip bright yellow. Iam
indebted for the detection of this species to my relative, Mr.
Alfred Bolus. It is somewhat intermediate in character between
D. rufescens, Swartz, and D. pygmea, mihi, but quite distinct
from either. From the first it differs by its wider galea,
narrower lip, deeply lobed petals, and different column and
pollinarium ; from the latter by its long filiform spur, differently
shaped petals, and larger size. At its flowering period the
leaves are generally withered. The flowers appear to vary in
size more than is usual. It was tolerably abundant where found,
though, so far as hitherto known, confined to an area of two or
three acres.

to lanceolate, obtuse spreading, about 4 mill. long; rostellum
nearly erect, ovate, with short arms; stigma cushion-shaped, 3
lobed; ovary cylindrical, 1°5 em. long.

Described from numerous living specimens. Flowers deep but
bright golden yellow. I was long familiar with this wide-spread
species in its usual colour (rosy pink, often with carmine spots) ;
but it is so unusual for Cape Orchids to vary from such a colour
into yellow that when I first found this I could hardly suppose
it to be the same species. Yet it is undoubtedly so. The species
varies somewhat in the length of the spur, those of the present
form being amongst the shortest; but I have found equally short
spurs amongst the red-flowered form. To quote Burchell’s
number is, I must confess, something of an assumption. His
specimens exactly resemble mine, and were collected in the same
locality 75 years earlier. But of the colour he says nothing in
his diary, and the specimens afford no indication; we may only
conjecture they were yellow. The pink-fl. form is in cultivation
in England, and I saw a fine specimen at Kew in 1891, which
was figured in the Bot. Mag. t. 7206, and which was more
luxuriant than I have seen it in its wild state. The nearest con-
gener of the species is D. caulescens, Lindley, represented in our
next plate; with D. venosa, Swartz, for which Lindley mistook
it, it has very little affinity. Lindley placed these species in the
section Coryphza; to which indeed they have some resemblance.
But I think their prominent rostellum,—a character not very
obvious in dried specimens, together with some other features,
point them out rather as members of the Eu-disa group.

ovaries; side sepals broadly oblong subobtuse, mucronulate
below the apex, spreading, 1 cm. long; odd sepal galeate obtuse
erect, produced at base into a short conical acute pendulous spur,
the whole about as long as the side sepals; petals broadly
obovate, partly exserted; lip linear-subulate, very acuminate,
slightly longer than the side sepals; rostellum erect, with short

divaricate arms; stigma cushion-like, 3-lobed; ovary slender
cylindrical.

Described from several living and dried specimens. Colour of
the sepals and lip pure white, petals white with light purple —
stripes, or sometimes entirely purple. In the dried state the
flowers of this species are puzzlingly like those of D. tripetaloides,
and the two species are often confused in herbaria. Nevertheless
it is quite distinct, and may usually be distinguished by the
character of the remote leaves, which in the other species are
crowded at the base of the stem. Besides this the side sepals
are smaller in proportion to the galea, and, as noted, the petals
and lip are differently shaped, the former more erect and half-
exserted. The spur is somewhat variable in both, in D. tripeta-
loides it is usually thicker and blunter; but forms of the latter
occur in which it is more slender, and then the flower more
resembles externally that of the present species.

viscid surface of the pollinary glands on the under side; ovary
slender straight, capsule 1°8—2°5 cm. long.

Described from several living and dried specimens. Colour of
the flowers mostly pure white, the petals and lip sometimes
faintly streaked or spotted with pink or purple. A very distinct
species unlike any other, unless D. attenuata, Lindley, which I
have never seen in a living state, nor of which have I had an
opportunity of dissecting dried specimens. I suspect it to be a
mere variety. From all others the present species seems well
distinguished by its peculiarly twisted odd sepal, but this is not
obvious, nor indeed easily to be made out, in dried specimens.
The habit is very much that of D. Draconis, or D. Harveiana
(which belong to the same group) in miniature.

of the flowers varying from pale lilac to rose-red, with minute

able plant in the length and degree of curvature of the sepals, by
both which characters it is well distinguished from all its con-

Described from several living specimens. Flowers light pink
with lilac spots on the lip, tips of the petals and lip red. This
is a very elegant little species, and, generally, the small size of
its flowers distinguishes it from any of its congeners. Mr. R.
Schlechter, however, who has paid particular attention to this
group, is of opinion that the present species with Schizodiwm
rigidum, S. obliquum, and S. obtusatum, all of Lindley, should be
regarded as one species under the name Disa bifida, Swartz. As
to the three last named, I believe he is right. But though very
small specimens of S. obliquwm certainly much resemble the pre-
sent species, I have not yet seen plants which satisfy me that
the two species should be united, while admitting that quite
possibly they may ultimately prove to be members of one very
variable species.

. foregoing of the natural size; 4, flower, the sepals being removed, side
view; 5, ditto, viewed from aboye,—the latter figures enlarged;
6, Peritrichia sp., magnified 2 diameters.

An erect glabrous herb, 10-20 cm. high; leaves chiefly
radical, 5-6, linear-ligulate acuminate, 4-8 cm. long, passing
into leaf-like lanceolate erect sheaths ; raceme very short sub-
corymbose, 2-4-fi., bracts membranous, lanceolate or ovate,
acute netted-veined coloured, often enwrapping the ovary and
equally long; sepals ovate obtuse spreading-erect, about 2 cm.
long, or the anticous odd sepal a little shorter than the side
sepals; petals reclined, obliquely oblong, very obtuse, incurved
at the apex and folding over each other ; lip lanceolate-rhom-

boidal obtuse, somewhat fleshy, as long as the petals; anther
resupinate; rostellum short erect retuse; stigma cushion-like,
8-lobed ; ovary cylindrical, ribs twisted prominent, 1°8 cm. long.

Described from several living plants. Colour of the sepals
creamy white ; petals and lip white at base, then maroon for the
greater part of their length, tipped with deep orange. This
species is closely allied to D. Bodkini, mihi (Orchids of the Cape
Peninsula, p. 165, t. 18). It is, however, distinct, by its chiefly
radical leaves, shorter and membranous bracts, differently
shaped and differently set petals, lanceolate-rhomboidal lip, and
longer and more slender ovaries. In the living state its white
sepals render it easy of identification. Without doubt it belongs
to the same group as the last-named, which, before I knew this
species I called Orthocarpa, because of the untwisted ovary, and
the resulting posticous lip. But in the present species the same
result, or nearly the same, is produced in a curiously different
way. The ovary has here nearly a whole turn or twist (in most
Dise it has a half-twist) and this, of course, brings the lip also
into a nearly posticous position as regards the axis of growth.
This is the only instance of the kind I have ever seen in the
genus. The small aborted branch with a single flower near the
base of the plant represented, only occurred on one specimen
and was doubtless the result of some accidental check to the
growth.

Upon one of the flowers was found a beetle, Peritrichia sp., as
my friend M. Peringuey informs me, belonging to a group of
well-known fertilisers, and which had a pollinium attached to its
thorax. This being only the second instance of an insect
actually carrying orchid pollen which I have seen during many
years’ study of Cape orchids, I have thought it desirable to
figure it with the plant.

obovate, very obtuse or truncate, 3 mill. long; anther reclined ;
arms of the rostellum shortly divaricate, with a rounded inter-
mediate boss; glands distant.

Described from numerous living specimens. Colour of the
sepals pure white, the side sepals tipped with pink; petals and
lip golden yellow. A small but very lovely and delicate little
species hitherto only recorded from Table Mt., where, with D.
rosea, Lindley, it studs the little ridges of turf below or between
the rocks which face the rising sun on the eastern side of the
mountain. The specimen drawn is considerably above the
average size, in fact the largest I have ever seen. More
usually they are less than a span high, and the lower part of the
stem is sunk deeply in loose turfy soil. To see this and its com-
panion in their glory the lover of nature should climb the
mountain very early in the morning after rain in September,
when the rays of the low sun darting through each tiny drop of
water on the flowers shows alternately the brilliant sparkle of the
diamond and the softer restful clouding of the opal.

Glabrous erect, 30-60 cm. high; tubers oblong or obovate,

closely-clasping sheaths ; raceme laxly 3-6-fl., bracts lanceolate

mucronulate below the apex, spreading, about 1°6 cm. long; odd

long as the side sepals, with a short inflated horizontal spur, 4

mill. long; petals reclinate, roundish oblong in the lower part,
then suddenly bent upward at a right angle and dilated, the
rounded cuneate extremities forming together a green eye-like
centre to the flower; lip oblong obtuse waved spreading, at
length angularly revolute; anther reclinate; gland most usually
single oblong, longer than wide (or more rarely 2); rostellum 3-
cleft erect ; ovary clavate-cylindrical, 1-1°2 cm. long.

Described from numerous living specimens. The sepals are
an intensely bright and beautiful blue ; the petals usually purple
below, with a bright green upper limb; lip pale blue or white,
edged with dark blue or purple. I have seen one plant with all
the flowers pure white, except that the petals and lip were edged
with a faint pink. Lindley described the flower as having two
pollinary glands. Reichenbach (De Pollinis Orchidearum Genesi,
p- 31) found specimens with both one and two glands. Both
these writers dissected dried and soaked flowers only. I have
never been able to find more than one gland, although I have
examined very many plants. On this variation Reichenbach
(loc. cit.) observes :—There are either two (or three ?) genera
with exactly the same external appearance and different gyno-
stemia, or one genus with a 2- (or 8-?) morphous gynosteme.
Lindley also describes a dorsal linear appendage, tuberculate on
either side, and situate in front of the anther. An inspection of
Lindley’s drawing shows that this organ is that which I have
called the middle lobe of the rostellum ; while his middle lobe is
apparently a fold of the rostellum drawn out in the dissection of
the dried specimen, but which is quite invisible in the living
state. It is one of the commonest species within our limits, has
a rather long flowering period, and attracts universal observation
by its beauty and brilliancy; so much so, that Lindley, in dedi-
cating it to the great astronomer, Herschel (who also was a great
orchid-lover and cultivator), felicitously speaks of it as ‘‘ species
hee pulcherrima colore coli australis intense ceruleo superbiens.”
It is very generally accompanied by D. ferruginea, Swartz. Its
nearest ally seems to be D. purpurascens. The drawing from
which Ker’s figure was taken was made at the Cape in Masson’s
time, and in spite of repeated efforts it does not yet appear to
have been successfully grown in England. It may be expected
that this difficulty will eventually be conquered, and if so the
species will soon become deservedly popular amongst orchid
cultivators. Horticulturists will do well to remember that during
its flowering period in its native home the plant receives little or
no water to its roots, being dependent for moisture on what is
stored up in its large tuber, and upon the occasional mists which
envelop the mountain sides,

Described from numerous living specimens. Colour varying
from a bright to a dark orange vermilion. I have seen one or
two plants with deep cream-coloured flowers; these are very
rare. The species is abundant on Table Mt., and largely sold in
bouquets in the streets. It was for long confused with D.
porrecta, Swartz, an error originating with Thunberg, continued
by Ker and Lindley, and only finally cleared up by Mr. N. E.
Brown, of the Royal Herbarium, Kew, who examined the type
sheets in the Swartzian herbarium, now at Stockholm. He
found that D. porrecta was the plant that had been called by
Sonder D. Zeyheri, and which is figured in our next plate. So
far as is at present known the present species is an exclusively
western plant, the easternmost recorded station being Swellen-
dam; while D. porrecta is chiefly south-eastern in its distribution,
only just touching the South-western Region at Hland’s River

rigid, nearly straight, erect, with distant acute sheaths, clothed
at base with the fibres of old leaves; spike oblong many-fl., 5-
10 cm. long, bracts lanceolate acuminate membranous, about as

long as the ovary; side sepals elliptical-rotund obtuse, mucro-
nate below the apex, about 8 mill. long; odd sepal galeate ovate
emarginate, produced at base into a cylindrical obtuse ascending
nearly straight spur, 3-4 cm. long; petals very small, hidden
under the galea, falcate-oblong, eared at base; lip oblong or lan-
ceolate subacute spreading-deflexed, 1 cm. long; rostellum short;
glands approximate.

Described from several living and dried specimens; the
drawing made from a plant sent by Mr. J. Glass from near
Grahamstown. Colour of the galea chiefly a rich orange
vermilion, varying in shade, the margins as also the sepals,
petals and lip orange. This species seems to take the place in
the South-eastern Region of D. ferruginea in the South-western.

Hab: South-eastern Region; Cars Conony: in moist shady
places; near King William’s Town, March, 1841, Rev. J. Brownlee ;

Sim, 14.—Trans-Vaat Repusiic: summit of Makwongwa Range, near
Barberton, alt. 15380 met., 2. Galpin, 1257.

Plate 40. Fig. 1, flower, front view; 2, odd sepal; 3, one of the
side sepals ; 4, a petal, under side; 5, ditto, upper side,—all the fore-
going magnified about 3 diameters; 6, lip, magnified about 10 diams. ;
7, column, front view; 8, one of the pollinia,—the latter figures
variously magnified.

Stem erect terete, somewhat flexuous, distantly leafy, the base
enclosed in a long sheath, 15-37 cm. high; leaves 3, cauline
remote oblong-lanceolate acute spreading or ascending, faintly
3-nerved, the lowest 6-11 cm. long, the upper gradually smaller;
raceme subpyramidal, 3—12-fl., flowers spreading, bracts leaf-like
about as long as the ovaries; side sepais semi-ovate spreading or
protruding and deflexed, about 1 cm. long; odd sepal (together
with the petals) galeate funnel-shaped acuminate, tapering gra-
dually at base into a slender arched spur, 2-2°5 cm. long; petals
oblong, as long as the mouth of the galea; lip linear erect, as
long as the stigma (scarcely 2 mill.), and closely applied to its
front; rostellum ascending almost vertically above the stigma,
the posterior middle lobe rather large; glands of the pollinia
distant; ovary cylindrical, tapering at base into a short pedicel.

Described from several living specimens received from Gra-
hamstown, and from dried specimens. Colour of the flowers
mauve, with dark purple spots on the sepals and petals. A very
pretty and distinct species worthy of cultivation. From the
elevation it reaches it cannot be tender, and the tubers would
probably bear a little frost. Had the genus Disa not already
been one of large size and very diverse structure I might have
been tempted to follow Reichenbach in reducing the present
to it. But the agglutination of the petals to the odd sepal does
not occur in that genus, nor the remarkably small and peculiarly
formed lip. The former character and the occasional clinging
of the lip to the front of the stigmatic cushion plainly indicate a
transition towards Disperis. But the distinction remains pro-
found by the peculiar and much more differentiated character of
both lip and column in the latter genus.

A glabrous herb 18-60 cm. high; stem erect terete, the base
enclosed in a long acute sheath ; leaves 3, cauline remote linear-
lanceolate acute 3-nerved, the lowest 10-13 cm. long, the upper

spherical, 8-12-fl., 1°8-3 cm. long, bracts leaflike lanceolate,
shorter than the ovary; side sepals lanceolate acute, 6 mill. long ;
odd sepal (with the petals) galeate funnel-shaped, tapering

clasping the base of the stigma, lamina free linear erect, about
1 mill. long; arms of the rostellum elongate parallel approximate.

Described from several dried specimens, and a raceme of each
preserved in spirit. Mr. Galpin notes the flowers as ‘‘ white, the
petals purple spotted.” The species is distinct by its petals and
its very short raceme. ‘The variety major looks at first sight
different, but there are too many points of identity to justify
specific distinction. Im examining flowers of the latter, the
clands seemed to be covered with a sort of indusium of nearly
the same size and shape as the gland itself, and quite separable
from it. These may have been produced by the action of the
spirit on the viscid matter of the gland, and need further
examination in the living plant.

A slender glabrous herb, a span or more high; stem erect sub-
flexuous, rather flaccid; leaf solitary, about half-way up the
stem, cordate semi-amplexicaul acute veined, 2°5-6°5 cm. long;
flower usually solitary sessile, sometimes 2-fl. the upper on a
slender pedicel 1-1°3 cm. long, bract foliaceous shorter than the
ovary; side sepals ovate acuminate horizontally spreading, the
upper portion deflexed, about 1 cm. long, widely saccate in the

middle, the sac or spur short broad and truncate; odd sepal
galeate, rising about 1 cm. high, the acute point deflexed nearly
to the base of the column; petals obliquely lanceolate, very
acuminate, acutely toothed on the outer margin; lip nearly
erect, rising from a ligulate base along the column, then expanding
upward into a somewhat fiddle shape, contracted and channelled
to the blunt glandular apex, appendage hanging from a little
above the middle in front, and reaching more than half-way
toward the base, acute, curved forward, flat appearing terete by
its revolute margins; rostellary arms spreading horizontally,
apices dilated oblique recurved.

Described from 2 living specimens from Grahamstown, which
are represented in the plate, but I afterwards saw some much
larger ones from Komgha. Colour of the flowers pale cream
yellow, with light green dots on the galea, and a hairy purple
patch on the petals. In the Kagaberg specimen the leaf was
very smooth and shining, and somewhat livid below. The
general structure of the lip is like that of D. secunda, but it is
more erect. Reichenbach’s description does not agree well with
the plants I have examined, and was no doubt drawn up upon
dried specimens. But I have seen at Kew a drawing of his type,
with a copy of the attached label marked ‘‘ Cap. B. Spei., Dr.
Krebs ded. 1888,” now in the Royal Herb. Berlin, with an
analysis of the flower, and this leaves no doubt of its identity.
Both Dr. Krebs’ specimens have the pedicel and bract of a second
flower, which has either dropped or was aborted. Dr. Krebs
was resident for some time at or near Bedford, whence he sent
many plants to Europe, and he probably collected his specimens
of this species also on the Kagaberg.

emarginate, clawed at base, the appendage rising thick and
columnar, then separating into two strap-shaped arms curved
horizontally forward, truncate and toothed at the apex; rostellum
bipartite beaked, each arm bearing one of the erect distant cells
of the anther on its anterior part; stigmas 2, pulvinate.

Described from several living and dried specimens. The limb
of the lip and the tips of the petals are bright golden yellow, the
rest of the flower pale yellow; all parts except the side sepals
are very fleshy. Readily distinguished by the forward-curving
arms of the appendage to the lip, and the crisped leaves. The
former character may be compared with C. microglossum, but the

sepal; 4, petals; 5, side sepals; 6, lip, front view,—the last four being
somewhat flattened out artificially ; 5, side sepals, side view, natural

8, column with lip, viewed obliquely from the front; 9, ditto, from the
back; 10, column, (s) one of the two stigmas, (a) anther, (r) rostellum,
(g) gland of the pollinia, (L) point of attachment of the lip; 11, one of
the pollinia,—all the latter variously magnified.

A glabrous erect robust herb, 15-35 cm. high; stem straight
leafy ; leaves several strap-shaped acuminate erect-incurved, 6-10
cm. long, the upper gradually smaller, the sheaths almost entirely
covering the stem; spike oblong, densely many-fl., bracts ovate-

lanceolate acuminate withered and blackened towards the apex,
longer than the flowers; perianth more expanded and more erect
than in the rest of the genus; odd sepal oblong, very obtuse;
side sepals anticous, joined for nearly their whole length into a
single trowel-shaped emarginate piece ; petals somewhat square,
concave, the outer angles rounded, margin crenulate; limb of
the lip linear acute deflexed, appendage widely clawed at the
base, then subspathulate and curved forward above, keeled in
front; column of two horizontal strap-shaped arms standing
edge-wise closely applied to each other and curving forward, the
outer one bearing at either extremity a cell of the anther, the
inner bearing the rostellum with the gland; stigmas 2, situate
in front upon the inner process, one upon either side of the lip at
its base near the point of its attachment.

Described from several living plants. Colour of the flowers
smoky or ashy-brown, with darker stripes on the petals; limb of
the lip pale green, the appendage dark emerald green, anther-
cells rosy, rostellum purple. The flowers are about 5 mill. long,
and 7 mill. wide. The species is a very distinct one and little
resembles any of the other Corycia. The hood, composed, as is
usual, of the odd sepal and the petals, is not bent down and con-
tracted as is generally the case, but stands nearly erect and
somewhat expanded, as in Pterygodium. It must be admitted
that this similarity of perianth in such species as the present
one and Pt. carnosum almost breaks down the boundary of the
two genera; nor does the column help us much to form a new
one, since there are considerable differences of structure amongst
the species of each genus. Ina general re-arrangement of the
genera of Orchidez both Corycium and Pterygodium should,
perhaps, be united with Ceratandra.

line and somewhat cowl-shaped, convex above, obtuse and eared
at base; cells of the anther anticous erect; stigmas 2, situate in
front on each side on the apices of a horse-shoe-shaped cushion.

Described from numerous living and dried specimens. Colour
of the flowers clear sulphur-yellow. Resembles C. orobanchoides
and C. excisum, but is usually taller and more slender than
either, with smaller flowers, and a different lip. The figure
quoted from Bauer’s rare book of beautiful drawings was clearly
drawn from dried specimens, and is, in some respects, misleading.
Ker’s figure in the Journ. Sci. R. Inst. Lond. vol. vi, t. 1, f. 1,
quoted by Lindley for this species, belongs to C. crispum, Swartz.

A slender delicate pale-coloured glabrous herb, 5-15 em. high ;

linear-lanceolate acuminate, 2°5-4 cm. long, the upper smaller ;
flowers 1-2, distant, about 1:2 cm. long, 1°8 cm. wide; bracts

ceolate acuminate concave or almost saccate towards the base;
side sepals ovate concave spreading; petals nearly semi-orbicular,
the upper margin bilobed, rounded below, very concave, limb of
the lip saddle-shaped with distinct hanging flaps and a narrowed
point, appendage fleshy, produced into two large erect ear-like
lobes at the top of the column, thence suddenly bent back-
ward and downward behind the column into a somewhat subulate
curved ridged acute piece;* arms of the rostellum horizontal;
stigmas 2; ovary obovate trigonous.

Described from several living and dried specimens. Colour of
the flowers pale sulphur-yellow; stem and leaves very pale. A
delicate and very distinct species, not easily to be mistaken for
any other, although Thunberg marked it as a variety ‘‘minor”’
of P. catholicum in his herbarium, to which in the general
structure of its lip it is undoubtedly allied. Mr. N. E. Brown,
who saw and examined the orchids of Thunberg’s herbarium, has
noted that the specimens were “‘1-, 2- and 3-flowered.” I have
gathered about a hundred specimens of which by far the greater
part were 1-fl., a few 2-fl., but I have never seen any with more
than 2 flowers.

* By.an error in the Orchids of the Cape Peninsula, p. 184, the descrip-
tions of the lip and the appendage were transposed, thus causing confusion.

Described from three living, and two dried specimens. Colour
ofthe flowers dull red, the appendage yellow. The species has
the habit of Pt. venosum, with which it is sometimes found
growing, but as may be seen here, it is very distinct from that,
or indeed from any other known to me. It seems to be somewhat
rare, and hence I have cited in full all the recorded stations ;
most of the later collectors have only obtained one or two speci-
mens; how many Zeyher distributed I have no means of knowing.
This is one of the several species which have been found on the
Cape Peninsula since the publication of my monograph on the
Orchids of the Cape Peninsula (1888), and hence does not
appear there.

much shorter than the flowers; flowers spreading, large; sepals
linear-lanceolate much acuminate spreading, 2°5-3°3 cm. long ;
petals oblong-lanceolate acute veined, horizontally deflexed, about

as long as the sepals and 2—8ce wider; lip as long as the sepals,
oblong or elliptical, more or less obscurely 3-lobed, side lobes

middle lobe much larger, narrowed to an obtuse point, furnished
below the middle with a shallow obtuse gibbosity hairy within,
a few raised but low longitudinal ridges towards the base, spur
slender incurved, 4—7 mill. long; column short, 5-8 times shorter
than the lip.

Described, and the figure drawn, from a living plant which
flowered in the Royal Gardens, Kew, June 21st, 1898, sent by
Mr. Allison from Natal; with this I have collated the dried
specimens named above. Colour of the sepals green, petals and
lip yellow, or sometimes white (J'yson), the latter with several
purple stripes at base and a pale green centre. The species is
very distinct by its saccate or gibbous lip, though the shape of
this organ varies, being in some specimens almost exactly oblong.
The wild specimens have mostly smaller flowers than those
shown in the figure. The manner in which the petals are bent
down resembles that of H. Dregeana, Lindley. Mr. Schlechter’s
description was founded on dried specimens of Wood’s No. 4626,
which I have not seen. But he has seen my figure and re-
cognised its identity with his type.

on the upper surface and traversed by a single slender line, acute
curved or straightish, 2-3 mill. in diameter, 5-10 cm. long; flowers
small axillary, on 2-3-fl. peduncles, the latter 2-4 mill. long;
side sepals spreading ovate-lanceolate acute subcordate at base,

odd sepal ovate acute, all about 3 mill. long; petals somewhat
shorter, cuneate acute, with a small tooth near the apex, or
entire ; lip spreading, as long as the sepals, lanceolate in outline,
with 2 thickish obtuse erect-incurved lobules at base, 3-lobed
towards the apex, the side lobes short subulate acute, the middle
lobe much larger triangular acuminate, spur cylindrical, nearly
straight pendulous, 6-7 mill. long; column short; rostellum
broadly ovate at base, thence narrowed to the truncate apex;
gland single ovate, with a rhomboid-obcuneate stalk; pollinia
approximate spheroidal.

The plant figured is drawn from living specimens received
from Zululand, and flowered at Kenilworth near Cape Town.
For the description I have also availed myself of the specimens
of Sanderson’s No. 562, and his drawing from life, preserved in
the herbarium of Trinity College, Dublin. These show plants of
somewhat stouter growth and shorter leaves than mine, and the
drawing represents an apical tooth to the petals which is wanting
in mine; otherwise they agree well and are undoubtedly speci-
fically identical. ‘The flowers are cream-coloured or, according
to Sanderson, ‘‘ pale waxy yellow.”

REMARKS UPON THE GENUS Mystacipium, Lindley.

Lindley founded the genus Mystacidium on this species (in Hook.
Comp. Bot. Mag. ii, 206 (1886) ) which he had three years earlier
published as Angraecum capense. He there observes: ‘‘ With the habit
of an Angraecum this curious little plant has characters of so marked
a kind as to render it impossible to combine it with that genus. The
curious two-legged caudicula, each point of which is inserted into the
middle of a transparent gland, the naked rostellum, on which the legs
of the caudicula are placed without any protection from the anther,
and the two very curious bearded appendages that stand forward from
the upper angles of the column, are all at variance with the structure
of Angraecum and its allies.” In some remarks under Plate 7 (see
Part I. of this work) I expressed the opinion that Mystacidium could
not be maintained as distinct from Angraecum. But reconsideration
has led me to think that considerable weight may be attached to the
character of the ‘‘bearded appendages’’ which I have treated, I know
not whether rightly, as parts of the rostellum. These are peculiar,
and perhaps play an important part in the economy of fertilisation.
It is probably therefore better to retain Mystacidium, but to restrict
it to species which exhibit this character. Lindley’s ‘‘ two-legged
caudicula,’’ which are in some sort also represented by Harvey in his
ficures tt. 173, 174, 175 in Thes. Cap., I have failed to find, although
I have dissected several flowers. Can they be due to compression or
to any other change resulting from drying? Bentham (Gen. Plant.
iii, 584) characterises the gland as single. In this and the two fol-
lowing species I have always found two distinct glands, which do not
even touch one another. Lastly, although Lindley speaks correctly of
the ‘legs of the caudicula” as lying on the rostellum without any
protection from the anther, he did not, apparently, see that these pass
through the interstices between the segments of the rostellum and are
united with the glands which lie completely below, and cannot be seen
from above (as shown in figs. 8 and 9 of Plate 55).

2-3°8 em. long; racemes several, loosely 5-8-fl., 4-6 cm. long,
bracts minute cup-shaped membranous caducous; segments of
the perianth spreading, equal in length, acute or acuminate,
7-8 mill. long; side sepals lanceolate, odd sepal and petals
subulate ; lip orbicular at the base round the wide orifice of the
spur with one or two small lobules, thence suddenly contracted

into a narrow lanceolate limb, spur filiform curved, 3-3°5 em.
long; column short; rostellum beaked, projecting forward, trifid,
side lobes linear shortly bearded, at first straight becoming
divaricate or curved after the removal of the pollinia, the inter-
mediate lobe lanceolate acuminate nude; glands under the
rostellum near its apex near together, with separate filiform
stalks; pollinia nearly globular.

Described and drawn from living specimens sent by Mr.
Flanagan from Komgha, as above. Colour of the flowers white,
leaves and aerial roots dull green. This resembles the preceding
species, but may usually be distinguished by its smaller size;
its flowering season also is widely separated, being in May,
whereas M. filicorne flowers from Sept. to March. There is also
a superficial resemblance to Angraecum Flanagani (Plate 52), but
the shape of the lip and the structure of the rostellum are quite
different.

A delicate glabrous herb, a span or more in height; stem
erect or decumbent, very slender, 2-leaved; lower leaf radical
spreading ovate acute frequently undulate, 2°5-3°5 cm. long,
the upper remote linear acuminate much shorter; raceme laxly
3-6-fl., bracts lanceolate, about as long as the ovary; flowers
suberect, about 1 cm. long; sepals spreading, the lateral oblong
acute, the odd one a little wider ; petals ovate, obliquely narrowed
to the base, incurved, about half as long as the sepals; lip

spreading, clawed at base, the claw concave gibbous adnate to
the column, limb ovate acute entire, or sometimes with a small
tooth on each side just beyond the middle, shorter than the
sepals, about 4-5 mill. long; anther broadly ovate, pollinia
spheroidal, with separated naked glands; stigma rather large,
horse-shoe-shaped, depressed, margined except at the top by the
claw of the lip; ovary cylindrical.

Described from numerous living specimens brought by Mr.
Flanagan as above, during an arduous expedition made by him
to the summit of the little-explored Mont-aux-Sources, in Jan.
1894. Colour of the sepals pure white, petals pink, lip white
with pink edges and a central green nerve; the cavity of the
claw green, the outer and under surface of the gibbous base
marked by two round green spots. This interesting species is
quite distinct in appearance from any other South African
Orchid. By the structure of its flower it is allied to Schizochilus
(see Plate 18 in Part 1 of this work), which, indeed, is also united
by Mr. Schlechter with Platanthera, but the appearance is not at
all similar.

The drawing of the whole plant is a copy of one by the late
Mr. Sanderson, of Natal, made from life; the analytical parts
and the description are from one of Mr. Wood’s dried specimens.
General colour of the flowers purplish rose, with darker spots in
various places. This species is a South-African representative
of the group of East Indian orchids which Sir Joseph Hooker, in
the Flora of British India, regards as Habenariae, and has
called Phyllostachya, characterised chiefly by large flowers in
the axils of sheathing leaves, by the absence of stigmatic pro-
cesses, and by a greatly reduced rostellum.

the lip. A handsome and widely-distributed species, with delight-
fully fragrant (violet-scented) flowers. The limited size of the

ceolate or oblong acute, the lower 6-12 cm. long, the upper
eradually smaller; spike narrow, loosely 5-10-fl., bracts ovate
acuminate, almost as long as the flowers; sepals lanceolate
acuminate, 7-9 mill. long, the side ones spreading, the odd one
erect and somewhat bent downward; petals erect oblong acute,
obscurely toothed at the apex, a little shorter than the sepals
and incurved above the column; lip anticous horizontally pro-
jecting or bent downward, somewhat longer than the sepals, the
claw boat-shaped nearly as long as the blade, the blade suborbi-
cular obtuse or cuspidate, minutely crenulate, traversed in the
middle by a longitudinal coloured scarcely elevated callus;
column erect subcylindrical; anther terminal ovate, cells
parallel, without tubercles ; rostellum folded between the cells
of the anther; glands of the pollinia ovate, approximate in the
bud, during flowering retracted and almost hidden under the
base of the rostellum; stigma in front of the column depressed
with a raised margin; ovary somewhat prismatic, with promi-
nent ribs.

Described and drawn from living plants sent by Mr. Sim from
the Dohne Mt. I have since seen it growing in many places in
Fingoland and Tembuland, and it is clearly a widely-distributed
plant, ranging from the Amatola Mts. to the Houtbosch in the
northern part of the Trans-Vaal. The colour of the sepals is
green with brown tints, petals bright green with translucent
dots, lip white with a broad pale purple medial band. Mr.
Schlechter regards this species as the type of a new genus, as
quoted in the synonymy above. The only divergence from the
older species of Brachycorythis which I have been able to find is
that in the latter (or, at least, in B. ovata, see preceding plate)
the stigma is depressed or excavate from the general level of the
column, while in this species the stigma is raised as a whole
above the general level of the column, and the stigmatic surface
is then hollowed out. To this may be added that the column is
a little longer. Apart from this, the general similarity in the
type of the flower, and especially of the lip, to Brachycorythis
is, | think, somewhat striking.

also resembles H. malacophylla, Reichb. f., but in that species the
leaves always turn black in drying. The relative length of the
anterior and posterior segments of the petals is in this, as in
several other species, very variable. Reichenbach’s H. Gerrardi
only differs by the anterior being shorter, Lindley describes it
as longer, while the plant from which our drawing was taken
exhibits them as nearly equal.

A glabrous erect herb, 12-40 cm. high; stem straight leafy ;
leaves lanceolate acuminate 1-nerved imbricate, 2-6 cm. long,
passing into bracts; spike cylindrical usually densely many-fl.,
2-2°5 cm. in diameter, flowers somewhat squarrose, bracts
lanceolate the lower exceeding, the upper slightly shorter than
the flowers; side sepals lanceolate acute reflexed, 6 mill. long;
odd sepal ovate somewhat hooded, of the same length; petals
undivided obliquely lanceolate acute, adhering to the odd sepal;
lip undivided linear obtuse rather fleshy, widened at the base,

margins revolute, 6 mill. long, spur obtuse inflated about as long
as the limb; clinandrium erect very obtuse, caudicle-bearing
arms of the rostellum short incurved, longer than the subulate
stigmatiferous processes.

Described and drawn from several living specimens, for which
IT am indebted to Mr. J. Glass, and which were much finer than
those from which my first description of the species was drawn
up. Colour of the flowers green. The leaves are occasionally
somewhat glaucous. The species is peculiar by its short flowers,
resembling those of H. laevigata, Lindley (see preceding plate), to
which it is most nearly allied, but with a different lip and column.
The narrowing of the odd sepal and petals to a point is a marked
characteristic. The distribution is peculiar; no doubt further
research will result in its being found between Grahamstown and
the Trans Vaal.

An erect glabrous herb, 10-20 cm. high; stem straightish few-

em. long, the upper gradually smaller passing into erect lanceo-
late acute bracts shorter than the internodes; raceme short,
loosely 5-10-fi., bracts lanceolate reflexed, scarcely shorter than
the flowers; sepals oblong obtuse, all of equal length, the lateral
ones subfalcate, about 5 mill. long; petals oblong very obtuse,
margin crenulate, a little shorter than the sepals; lip tubular-
galeate, with a free erect apex, margin crenulate, spurs filiform
twice as long as the ovary; column short; rostellum projecting,
subtriangular, rather thick, glands large placed on either side

behind the apex; stigmatiferous lobe nearly square, cushioned,
about as long as the rostellum.

Described and drawn from several living specimens sent to me
by Mr. Schlechter from the station above named. Colour of the
flowers yellow, with three faint green veins on each seoment. In
its floral characters this comes nearest to S. ochroleucum, mihi —
(figured in Orch. Cape Penins., t. 26), which I fear may be only a
form of S. humile, Lindley. But the leaves are differently
arranged, and it is still more diverse in the shape of the
rostellum and the position of the glands. It is also allied to
S. stenopetalum, Lindley.

its very small flowers and peculiar rostellum. From S. retusum,
Lindley, which also has small flowers, it may readily be known
by its two lower leaves, laxer and longer spike, and the free apex

Characters of the typical form (see preceding plate) differing

Described and drawn from a living plant gathered at Kenil-
worth, near Cape Town. Colour of the side sepals light pink,
sometimes nearly white, rest of the flower white with faint green
lines. I am indebted to Mr. Schlechter, who collected the typical
form, for pointing out to me the essential identity of the present
plant (which Lindley mistook for and published as S. parvi-
forum, Swartz,—a very different plant) with Lindley’s own S.
stenopetalum. When Mr. N. E. Brown had discovered, by his
laborious and careful examination of Thunberg’s herbarium,
that Lindley had gone wrong, it seemed that a new name was

required for the present plant, and hence my name. In my
later description I noted that the width of the sepals and petals
was variable; but I was then unacquainted with S. stenopetalum.
The present variety appears, 80 far as we know at present, to
extend over a wider range, and to inhabit the extreme western
portion of the Colony, while the typical form is a more easterly
plant.

straight leafy; radical leaves 2, laxly ascending, ovate or lanceo-
late acute, 7-12 cm. long, cauline 2-3 reduced to stem-clasping
sheaths; spike oblong or cylindrical, densely many-fl., 3-4 cm.

in diameter, bracts at length reflexed, lanceolate acuminate,
longer than the flowers; side sepals spreading decurved, oblong
obtuse subfalecate, strongly 1-nerved below, about 1°5 cm. long;
odd sepal a little shorter, deflexed; petals narrower, linear-
falcate, as long as the sepals, all connate below for about 4 of
their length; lip galeate oblong, with a dorsal ridge, about
1:2 cm. long, free apex ovate obtuse crenulate, spurs funnel-
shaped above then filiform, variable in length, more or less
exceeding the ovary; rostellum short oblong, wider than long,
subtruncate or notched at the apex, with a minute sinus on
either side the middle for the passage of the caudicles of the
pollinia ; glands approximate lying flat and entirely upon the
upper surface of the rostellum; connective of the anther free
from the column ; stigmatiferous lobe semiorbicular, cushioned,
much larger than the rostellum ; ovarium ovate, 6-10 mill. long.

Described and drawn from a living plant sent by Mr. Flanagan
from the Kei R. mouth, and from numerous dried specimens.
Colour of flowers dingy white, variably tinged or blotched with
pink, red or dark brown-red. A variable and widely distributed
plant, well characterised by its deeply connate sepals and petals,
by its very short broad ovary, and by the glands lying wholly
upon the rostellum, and not in recesses on the same plane with
it, as is usually the case. The flowers are amongst the largest
of the genus. For the identification of this species with S.
militare, Lindley, we are indebted to Mr. N. E. Brown, of Kew.

A glabrous erect herb, 3-1} feet high; stem subflexuous leafy;
leaves about 4-5 along the stem, ligulate acuminate erect, the
lowest about 10 cm. long, the upper gradually smaller passing
into bracts ; spike loosely many-fl., 9 cm. long (or, according to
Lindley’s description and Burchell’s specimen, ‘‘ almost a foot

long, very dense, cylindrical, the flowers closely appressed’’),
bracts lanceolate the lower ones about as long as the ovary ;
sepals broadly ovate subobtuse, 7 mill. long, the side ones
spreading, the odd one deflexed; petals erect-spreading oblong
narrower and a little shorter than the sepals; lip lanceolate
erect, with two parallel coloured stripes; column erect stipitate,
shorter than the perianth, furnished behind with two horn-lke
processes (staminodes ?) as long as the rostellum; rostellum
terminal erect thick triangular truncate, wider than the column ;
cells of the anther placed one on each side of the stigma, parallel
distant ascending but scarcely erect; glands affixed to the base
of the rostellum, naked, distant; stigma in front rather large,
oblong or somewhat horse-shoe-shaped depressed margined ;
ovary subcylindrical channelled.

Described and drawn from a living specimen sent by Mr.
Schlechter, as above. Colour of the perianth lilac, the lip
bearing two longitudinal parallel stripes, the anther a little
darker, outer margins of the rostellum red. Respecting this
most interesting and rare plant, the reader is referred to the
remarks under Plate No. 26 (Pachites Bodkini) in the first part
of this work. Burchell’s type specimen in herb. Kew is so
much larger and more densely-flowered than that figured that
one might hesitate to identify them, especially as the flowers in
that are rather too far advanced to give entirely satisfactory
results. However, a careful dissection and drawing have left
little doubt in my mind of the correctness of the identification.
Lindley speaks of the anther as “‘resupinate’’; and it appeared
to me that the rostellum had fallen forward, age having altered
its position, as is often the case in the Ophrydeae. The genus
seems to connect Disa with Satyrium, but has very distinct
characters of its own.—I may in this place ask the reader to
correct an error in Plate 26, where the numbers 38 and 4 of the
analytical figures, by an unfortunate mistake, have been trans-
posed.

the lower longer than the flowers; side sepals from a wide base
oblong subobtuse, obscurely 3-nerved, 4—5 mill. long; odd sepal
eucullate oblong or obovate obtuse, as long as the side sepals,
spur inflated obtuse nearly as long as the limb; petals rhomboid-

faleate, thickened in front, papillose; lip viewed from the front
oblong, very obtuse, viewed from the side clavate thickened and
fleshy, 8-4°5 mill. long; rostellum erect, obovate, with an ear-
like fold on either side towards the apex.

Described from the specimens quoted above, the figure of the
whole plant drawn from Mr. Schlechter’s. In the latter, the
flowers were dingy yellow tinged with red-purple; in Mr. Guthrie’s,
yellow only. The chief characteristic is in the thickened lip and
petals, and the auricled rostellum. It comes near to D. multi-
flora, mihi, in its flowers, but the spike is always slenderer, and
the inflorescence usually less dense. It also somewhat resembles
D. micrantha, but the flowers are larger, and the spur and
column very different.

velvety; side sepals ascending broadly oblong very obtuse,
3 mill. long; odd sepal subgaleate hemispherical muticous or

emarginate, spur ascending cylindrical obtuse shorter than the
galea; petals included within the galea, incurved, from a wider
base erosulate on the upper margin linear-faleate toothed at the
apex, much shorter than the sepals; lip rhomboid acute (or,
according to Sonder, small, linear, membranous) with a small
pellucid gland at the apex resembling a dew-drop.

Described and drawn from Mr. Sim’s specimen from Mt. Kemp.
Colour of the sepals deep crimson, a lighter band on the edge of
the galea, petals rosy. A very well marked and peculiar species,
with some curious characteristics, especially the gland at the
apex of the lip. Mr. N. EH. Brown of the Kew Herbarium
satisfied himself, by dissection and comparison, of the identity
of Zeyher’s and Hutton’s plants; and I have compared Sim’s
with Hutton’s, and have no doubt of their being the same.
Respecting the difference of Sonder’s description of the shape of
the lip, this may be due to a shrivelling in the drying, or to a
natural variation, or to both causes combined. Nor does Sonder
mention the singular gland on the lip, but in both Hutton’s and
Sim’s dried specimens this is still quite clearly visible, and I do
not know how it can have escaped Reichenbach’s observation.
The species seems to be somewhat rare; Mr. Sim only found
one specimen, which he very generously contributed to my
herbarium.

Described from several living and dried specimens: the drawing
made from a plant sent from the neighbourhood of Worcester.
Colour of the sepals dull white, passing at the back of the galea
and the tips of the side sepals into brown-purple, petals pale
yellow in front with purple points, lip pale yellow. In habit this
resembles D. caulescens, Lindley (see t. 31 in the first part of this
work) and in the dried state might be taken for it, but the floral
characters are abundantly diverse. Small and laxly-flowered
specimens might be confused with D. ocellata, mihi; but the
leaves of the latter are narrower and erect, and the galea is
oblong and acuminate. While most of our Orchids love a light
or even sandy soil, this seems generally to prefer a stiff greyish
clay. It is by no means a common species, and I cannot avoid
a suspicion as to the correctness of the single widely isolated
eastern station quoted from Cooper’s ticket.

rising above the stigma; anther reflexed, somewhat pendulous.

Described from several living and dried specimens, including
Drége’s types; the drawing from a plant gathered near Ceres.
Colour of the flowers white with a greenish yellow patch on each
side of the odd sepal down to the end of the spur, also on each
side of the side sepals, a purple stripe on the lip and on the edges
of the petals. A variable species as to the length and thickness
of the spur, and the amount of pubescence on the sepals and lip.
A very distinct species, not easily to be mistaken for any other.

A glabrous erect herb, 1-2 ft. high; stem stout straight leafy ;
leaves several erect-spreading lanceolate or linear-lanceolate
acute nerveless or many-nerved, 2°5-15 cm. long, much longer
than the internodes, gradually passing into bracts; raceme
ovate or oblong, loosely or densely many-fl., 4-7 cm. in diameter;
flowers spreading mostly longer than the veined acuminate

bracts; side sepals oblong obtuse apiculate, somewhat twisted,
1-2 cm. long; odd sepal posticous galeate oblong obtuse, spur
from a funnel-shaped base filiform, a little shorter than the
limb ; petals half exserted beyond the galea erect falcate-oblong
obtuse apiculate, 6-10 mill. long; lip spreading linear widened
and thickened towards the apex, a little longer than the sepals;
rostellum short; ovary slender straight, 1°5-2°8 cm. long.

Described from numerous living and dried specimens ; the
drawing from a living plant sent by Dr. Schoenland, gathered
near Grahamstown early in December, 1889. Colour of the
flowers clear rose-pink, with or without darker spots, or lilae
with purple spots. This is a very variable species, especially as
to the size of the raceme, the size and colour of the flowers, and
the texture of the leaves. In some specimens the latter are
strongly nerved, but this may be, as is often the case, the result
of drying. Of the numerous living specimens I have seen all
were nerveless. It is impossible to find any valid distinctions
between Sonder’s D. patula and the present species ; and I have
satisfied myself, after again finding a similar plant to that on
which my D. stenoglossa was founded, that it is only a de-
pauperated state of this species, with which I was, at the time
I described the former, but little acquainted. D. nervosa is most
nearly allied to D. pulchra, Sonder.

clavate straight.

Described and drawn from living plants sent in Jan., 1893, by
Mr. Schlechter, from Zuurbraak. Colour of the flowers white,
with dark purple tips to the petals and lip. A very distinct
species which must be somewhat rare, since it had only been

therefore greatly indebted to him for enabling me to figure it in

acute membranous, about as long as the ovary; side sepals
spreading-deflexed oblong acute, 1°8 cm long; odd sepal hooded,

the mouth suborbicular, 1°4—1°6 cm. in diameter, subacute, spur
ascending obtuse about 4 mill. long; petals included within the

Described and drawn from a living plant from the station first
above-named. Colour of the sepals blue, the lip and parts of the
petals violet, upper limb of the petals and spur yellowish green,
anther cells pink. Variable in the toothing of the lip, which is
sometimes nearly entire. Closely allied to D. graminifolia, Ker
(see Plate 87 in the first part of this work); but, besides the
considerable difference in the lip, the flowering season is widely
different, and I have no doubt as to its specific distinction. The
species seems to be confined to the southern part of the Cape
Peninsula; south of Simon’s Town it may often be found in
quantity. .

An erect herb, 13 ft. high; stem leafless subflexuous rigid,

side sepals erect-incurved ovate acuminate concave, 8 mill. long ;
odd sepal anticous horizontally projecting, somewhat spoon-
shaped, margin toothed, clawed at base, as long as the side
sepals; petals lying upon the odd sepal, approximate lanceolate
recurved or hooked and ciliate beyond the middle, emarginate

kidney-shaped, obscurely trilobulate and ciliate at the apex,
4-5 mill. long; anther suberect; rostellum short, produced on

large, with short caudicles; stigma flat; ovary straight clavate.

Described and drawn from a specimen received April, 1895,
from Miss C. B. Newdigate, gathered near Plettenberg Bay.
Colour of the sepals greenish yellow with bands of a steely blue
purple; lip petals and anther crimson. Iam greatly indebted
to my kind correspondent above named for the opportunity of
figuring this rare plant. Examination of fresh specimens shows
that there is nothing whatever to separate it from Disa; in floral
structure it agrees well with the other members of the group
Orthocarpa, differing only in habit and leaves. It does not,
however, seem to me to be advisable to place it in a distinct
section on that account only. I may add that a careful
examination of fresh buds did not confirm Lindley’s description
of the aestivation. He says, “‘[sepalo] intermedio mutico majore
antico lateralia aestivatione imbricante.”’ I found the lateral
sepals exterior, and to a considerable extent, though not entirely,
covering the odd sepal.

and hitherto the only collector of the species. Colour of the
flowers greenish yellow, with purple spots on the lip and on the
tips of the petals, the long filiform processes of the lip and petals
dark purple. A very distinct and curious species, as remarkable
for its much developed rostellum as for its peculiar petals and
lip.—Since the first part of this work was published I have
judged it better to maintain the genus Schizodium as distinct
from Disa on account of its peculiar habit and lip. Plates

of Disa torta, Swartz, and Disa clavigera, Bolus, must be taken

incurved, the angles rounded; lip linear at base, widened and lanceolate
above, decurved or hooked at the apex, muticous or furnished behind with
a lanceolate or toothed appendage; rostellum heart-shaped subobtuse,
with erect-spreading twisted arms at the base; pollinia quickly revolute
after withdrawal.

Described and drawn from living plants gathered near Cape Town.
Colour of the flowers variable: from a rosy purple which is darker on the
edges, to lilac; there is also a form with yellow or greenish flowers. In
the latter the lip is usually narrower above and often destitute of the
dorsal appendage, or sometimes present only in a reduced form. The
species is very distinct by the long claw-like points to the sepals, and the
form of its lip.

In Disperis the viscid surface of the glands of the pollinia appears to be
always directed towards the back of the flower. Fertilisation is therefore
probably effected by a retractive movement of the visiting insect. The
pollinia in this species, and I believe in most, become spirally revolute in
less than a second after withdrawal. The granules of the pollinia then
lie either nearly in a plane, or sometimes, as in D. purpurata (see
plate 91), they project in every direction. In either case they are more
or less well fitted for striking the stigma from any direction. Yet I found
in 1884, that of 100 plants of this abundant species only 13 had been
visited by insects, and only 7 had the stigma pollinated (Orch. of Cape
Penins. p. 86). It should be added, however, that there appeared to be
some deficiency in the viscidity of the pollinary glands, and that therefore
insects may in some cases have visited the flowers without leaving any
trace.

A glabrous erect herb, a span or more high; stem straight
loosely leafy; leaves 3-4, scattered, erect-spreading, as long as
or longer than the internodes, oblong or lanceolate acute, 2-6
em. long; raceme laxly 3-12-fi., bracts lanceolate usually longer
than the flowers; side sepals deflexed lanceolate acuminate
narrowed at base, 9 mill. long, spur obtuse 2 mill. long; odd
sepal of equal length hooded acuminate, with a very obtuse base ;
petals from a linear base ovate-lanceolate, obliquely twisted,
1-nerved; lip with a short linear claw adnate at base, thence

spreading at a right angle into two parts, the whole being some-
what fiddle-shaped, the front part wider oblong, covered in the
middle with several rows of purple papillae, the apex hooked or
upturned in a sharp knee-bent angle and very acute, the
posterior part (answering to the handle of the fiddle) linear with
involute margins, the whole appendage about 1 cm. long; arms
of the rostellum horizontal projecting linear straight divaricate-
spreading, spoon-shaped at the apex; anther and rostellum very
short.

Described and drawn from a living plant sent by Mr. Sim from
the Dohne Mt., March 16, 1893, and from several dried specimens.
Colour of the sepals purple, spurs of the side sepals green; petals
sreenish-yellow with dark green veins and spots; lip green, with
purple centre and crest of darker purple papillae. It is impossible
to know certainly whether this is Reichenbach’s plant. The
description of a species of so complicated a structure by the use
of few words is difficult, if not impossible; and that by the
author of this plant is far too brief. In such a case the student
ordinarily refers to the type specimen; but this is effectually
precluded by the terms of Reichenbach’s will, by which his whole
collection remains sealed at Vienna for twenty-five years from
the date of his death. It is a question whether the botanical
world generally would not have promoted the true interests of
the science and discouraged similar unworthy vagaries for the
future, by agreeing at the recent Genoa Congress that the usual
rule of priority of nomenclature should not hold good in any case
where the only type specimen existed in Reichenbach’s herbarium,
and where no other specimen named by him was available for
reference elsewhere. At present it can only be said that this is
probably Reichenbach’s plant. The species has a near ally in
D. Cooperi, Harvey (Thes. Cap. t. 172). The general type of the
lip is the same, the shape of the front part, however, being rather
oblong than heart-shaped; but the greatest difference is in the
arms of the rostellum, which are here straight, but in that
species are sharply knee-bent, a difference which I believe to be
of great specific value. I may also mention here that I have
dissected a flower of Cooper’s No. 1100, the type of D. Cooperi,
Harvey, that I found Harvey’s figure above quoted substantially
correct, as far as it goes, and quite undeserving of the sneer with
which it was treated by Reichenbach in Otia Bot. Hamb., p. 108.

in front of the flower, the sepal lanceolate vaulted, the petals
oblong concave much larger than the sepals; limb of the lip
superior ascending, transversely oblong, concave, crenulate
clawed, about 3 mill. long; the appendix larger deflexed tongue-
shaped bilobed fleshy, about 5-6 mill. long; cells of the anther
remote, situate at the ends of the arms of the rostellum; ovary
cylindrical, twisted above. ;

Described from several living specimens from Piquetberg, and
one from Hex R. Valley. Colour of the flowers greenish yellow,
with brown-purple stripes on the lip, and sometimes also on the
petals; sepals and bracts green, or sometimes brown on the
upper portion. A very distinct species readily known from any
other except Pt. Flanagani, mihi, by the reversed position of its
flowers, which is effected (as in Disa elegans, see Plate 35) by an
entire instead of a half twist in its ovary. It was first discovered
by Thunberg in 1774 near Piquetberg, where I also found it
tolerably abundant during a very pleasant botanical excursion,
with my friends Professors Guthrie and Bodkin, exactly 118
years later. Thunberg, like Drége at a later date, travelled
slowly northward by that route, and both gathered at the same
spot several very local plants which it was a great satisfaction to
us to obtain again in the same neighbourhood. Botanists will
always find the village of Piquetberg an excellent centre for
excursions.

A glabrous erect somewhat robust herb, 3-1 foot high; stem
straight densely leafy; leaves thickly imbricate erect-spreading
or often recurved at the apex, ovate or ovate-lanceolate acuminate
many-nerved, loosely sheathing the stem at base, 3-8 cm. long ;
spike oblong densely many-fiowered, bracts ovate lanceolate sub-
membranous, usually reflexed at the apex; flowers inverted,
about 1°2 cm. long, 1°5 cm. wide; side sepals spreading ovate-
lanceolate subobtuse many-nerved, connate at base; odd sepal
inferior deflexed, ovate-lanceolate, at first adherent to the petals
often becoming free; petals deflexed lanceolate subacute concave

incurved ; lip superior erect-recurved tongue-shaped, almost as
long as the sepals, furnished below the middle and near the base
with numerous small fleshy calli or warts, appendage rising from
the base of the limb oblong subfleshy, traversed by an elevated
nerve, half as long as the lip.

Described and drawn from dried specimens collected by Mr.
Flanagan as above. Colour of the flowers according to the
collector brown or smoky-grey, the bracts and foliage of a
similar tint, darker at the tips, the lip dark maroon. This is
the second species of this genus which has inverted flowers (as
compared with the remaining species of the genus), in which
respect and some others it is closely allied to Pt. inversum,
figured on the preceding plate. In habit and general appearance
it much resembles Corycium microglossum, Lindley (see Plate 46),
which has similarly dry and withered leaves and bracts. This is
one of Mr. Flanagan’s many interesting discoveries, and I have
much pleasure in associating his name with it.

A glabrous erect herb about a span high; stem slender nearly
straight few-leaved ; leaves usually 2-3, distant, the lowest spreading
lanceolate acute or acuminate, loosely sheathing at base, 6-8 cm.
long, the upper smaller more erect, somewhat cucullate, bract-like ;
spike loosely 1-3-fl., bracts lanceolate acute concave; sepals ovate-
lanceolate acuminate concave, about 1°2 cm. long; the side sepals
spreading, the odd one erect; petals somewhat rhomboidal concave,
slightly lacerate at the top, the front margin sinuate-incised near the
base; lip bent downward and backward oblong acute lacerate at the
top, 3-4 mill. long, appendage erect thick fleshy oblong narrowed
above and hollowed out at the apex (very similar to those of
Pt. catholicum and Pt. acutifolium) ; stigmas 2; ovarium clavate.

Var. cleistogamum: Spike usually more numerously flowered
(2-7-fl.) ; perianth connivent closed; petals lanceolate acuminate ;
lip ovate acuminate involute, with a tooth-like lobe on each margin
near the base, appendage none; column variously shaped, arms of
the rostellum(?) sometimes 4 equal erect, sometimes variously

arranged in pairs each bearing at the apex a small gland-like
more or less imperfect anther-cell containing aggregated pollen-
grains, sometimes few, sometimes empty (?), without any viscid
gland; stigma sometimes terminal undivided cushioned hairy, or
stigmas 2, ‘of which one is terminal, the other expanded into wings
on either side of the posterior pair of rostellary arms; capsule
clavate, seeds with a perfect embryo.

Described and drawn from living plants of both forms sent by Miss
C. B. Newdigate as above, and also in part from living plants of the
cleistogamous form only, sent by Mr. Glass from near Grahamstown.
Colour of the flowers sulphur-yellow; the whole plant dries a pale
straw colour. Of the normal form, which seems to be somewhat rare,
I received first a one-flowered plant which is figured, and subsequently
two taller but withered 3-fl. specimens. The cleistogamous form was
found abundantly at all the stations quoted. The species is allied to
Pt. catholicum, differing by the larger, more oblong, lacerate lip, in the
shape of the appendage of the lip, and in the incised petals. Its chief
interest lies in its exhibition of a cleistogamic form so different both in
its perianth and in its column from those of the normal form that it
might, if it stood alone, be taken as the type of a distinct genus.
Cleistogamy is not unknown in the order; but itis rare. Mr. Rolfe
has been good enough to refer me to the following papers and
instances: Dendrobium crepidatum, Lindley, noted by him in the
Kew Herbarium ;—Reichenbach fil., on Mazillaria rufescens, Lindley,
in Refugium Botanicum, vol. li, sub t. 183 (1882) ;—H. O. Forbes, On
Self-fertilisation in Tropical Orchids, in Linn. Soc. Journ. (Bot.), vol.
xx1, p. 547 (1885), where a case of cleistogamy in Chrysoglossum sp.
is recorded and figured in Plate 17, figs. 6-11 ;—H. N. Ridley, Notes
on Self-fertilisation and Cleistogamy in Orchids, in Linn. Soc. Journ.
(Bot.) vol. xxiv, p. 390 (1888), recording cases of cleistogamy in
Trichopilia fragrans, Lindley (Plate 16, figs. 1-9), and in Dendrobium
chryseum, Rolfe. None of these cases appears to throw any light upon
the present one. The erect processes shown in figs. 12 and 13 appear
to be homologous with the organs regarded as arms of the rostellum
in the normal form (see Orchids of the Cape Peninsula, p. 183, and
Plate 12, fig. 7); or they may perhaps be a development of the con-
nective of the anther. In this genus and in Ceratandra the anther-
cells are usually adnate to these arms, and this may also be seen in
Plate 48, figs. 6 and 7, of the present work. The anther-cells at the
apices of these arms in the cleistog gamous form are of variable deve-
lopment. Sometimes they are nearly perfect, the pollinia, however,
having no proper caudicle and viscid gland; in some cases the pollen
is reduced to a few isolated granules, and even sometimes (though
probably not in all of one flower) is wanting altogether. The presence
of four anther-cells, equivalent to two anthers, would be very curious,
and needs confirmation. No opened or punctured flower has, as yet,
been observed; no pollen has in any case been found upon the stigma ;
yet the ovaries have swollen, producing abundance of seed, and Dr.
Schoenland, who examined them, found the seeds to contain a perfect
embryo. The question remains, How is the fertilisation effected ?
This, with some other points in respect of this remarkable species,
must await for its elucidation a supply of fresh material, which Dr.
Schoenland, who has kindly assisted me in this matter, hopes to obtain
during the ensuing season.

A glabrous erect herb, 3-1 foot or more in height; stem
straight or occasionally flexuous, loosely and distantly leafy;
radical leaf spreading ovate or oblong acute, 6-10 cm. long, the
upper more erect smaller, passing gradually into bract-like
sheaths; spike cylindrical many-fl., bracts lanceolate deflexed,
flowers about 1:2 cm. long, 8 mill. wide; side sepals spreading
ovate acute or subobtuse ; odd sepal oblong very obtuse; petals
subtriangular, the upper margins folded over downward; limb
of the lip broadly triangular-hastate acute, with a spreading
tooth-like fold on either side near the base, appendage about
equally long erect cup-shaped, with an oblique margin entire or
emarginate or dentate in front; connective of the anther as-
cending incurved somewhat half-ring-shaped, the cells inverted,
glands inferior; arms of the rostellum adnate to the connective
of the anther; stigmas 2, placed one on either side of the
appendage of the lip, at its base.

Described and drawn from a living plant gathered near Cape
Town; and I have seen many others from other stations.
Colour of the flowers sulphur yellow, the whole plant drying
pale. Lindley separated this plant from Pterygodium because,
as he said, of “its anther being perfectly erect.” Bentham,
however, in Genera Plantarum, replaced it in Pterygodium,
calling the anther suberect, and I agree in this view. The
position of the anther is not widely different from that of
Pt. carnosum, Lindley, as shown in my Orchids of the Cape
Peninsula, t. 12, f. 7. In this species the connective of the
anther is differentiated from the rostellum, although they are
partially adnate. In other species these bodies seem to coalesce
into one.

ADDITIONS TO THE ‘ORCHIDS OF THE CAPE PENINSULA.’

In my work bearing the above title, published by the South-
African Philosophical Society in its ‘Transactions,’ Vol. V,
Part I (1888), there are enumerated 102 species of Orchids
growing within the limits of the Cape Penusula. Since then
thirteen more species have been discovered, bringing the total
up to 115 species. Pending the issue of a list with complete
descriptions, I have thought it would be useful to possessors of
the above work to have even a mere enumeration of the additional
species, with such brief notes as may aid in their identification.

Holothrix exilis, Lindley, var. brachylabris—Bolus, Icon. Orch.
Austr.-Afr. t. 14.—Table Mt., Schlechter.—Resembles H. villosa,
Lindley, but differs by its undivided lip, which readily dis-
tinguishes it.

Satyrium erectum, Swartz.—Table Mt., south side, Schlechter.
Habit of S. candidum, Lindley, but the perianth segments more
spreading, and rose-coloured.

Satyrium retusum, Lindley.— Table Mt., Schlechter.— Near to
S. Lindleyanum, Bolus, and §, bicallosum, Thunb., with longer
spurs than the former, and the apex of the lip not deflexed as in
the latter. Flowers small, white.

Pachites Bodkini, Bolus, Icones Orch. Austr.-Afr. t. 26.—Muizen-
berg, 400 meters, fl. Jan., Bodkin.

Disa conferta, Bolus, Icones Orch. Austr.-Afr. t. 28. § Monadenia.
—Cape Flats, near Rapenburg, fl. Oct., F. Guthrie. Flowers
small, the odd sepal destitute of any spur.

Disa Bolusiana, Schlechter, in Engl. Bot. Jahrb. ined. § Monadenia.
—Table Mt., 1000 meters, fl. Jan., Bolus, No. 4908.—Allied to
D. rufescens, Swartz, but with a deep cleft in the column
between the rostellum and the stigma.

Disa uncinata, Bolus; see Icones Orch. Austr.-Afr. t. 82.—Table Mt.,
several collectors.—Near to D, ocellata, Bolus, but with an oval
obtuse, not oblong acute galea. ;

Disa Draconis, Swartz.—Table Mt., Schlechter; also reported from
the Flats, near Diep River.—Closely allied to D. Harveiana,
Lindley ; for a summary of their differences, see the work above
named, p. 159.

Disperis Bodkini, Bolus; see Icones Orchid. Austr.-Afr. t. 96.—
Claremont Flats. —F lowers the smallest of the Peninsular species ;
helmet green, rest whitish yellow. Fl. Aug.
