name, publislied in Hooter's Joura.il of Botauy liis geiins Micropera, and xmier it lie dpsoribcd two
species {M. viridifiom and M. macukUi), one of which {U. viridifiora) is, nccoiüing to Linclley and
Sir Joseph nooker, a Succolahhm. The other (JV. ,mcula(,i) is rdso considered « Saccohbiim by
Messrs. Bcntliam and Hooker. Lindley, lioweTer, kept up DfJzeU's namo for tlic latter, as lio had in
tho meantime lUscoyered that his owu Micropcra is identical with Camm-oHi, to which lio therefore
himself reduced it (Joum. Lhni. Soc. Ill, 3S). Cmmvoih is allied to SUrcochHua, from whicli it is,
however, at once distinguishable by its dorsal anther, diflereiitly shaped lip, and elongated stems.
Sepals and petals breadly oblong; the lateral sepals connivent under
tho lip and partly adherent to it; flowei-s -75 in. across . . . 1. C. obfnsa.

1. CJM.Í.EOTIS OBTUSA, Lindl. in Bot. Reg. 1844, Misc. 73.
Stem stoiit, orect, leafy, S to 10 in. long. Leaves coriaccous, horizontal, lineai-oblong,
sliglitly and obliquely bifid at tho apex, not naii-owcd at tho base, jointed to the short
slicath; longtli 2 to 3 in., breadth -3 to -6-3 iu. Raccmes leaf-opposed, rigid, horizontal,
about as long as tho leaves ^^•heu in flower, slightly longer iu fridt; the poduuclc witli a
few short sheaths; raccm with about ten flowers of wliick only two to fom- open at a timo.
Flowers (fronr tlio tip of the dorsal sepal to the tip of the Up) -75 in. across; bract small,
ovate, acute; rachis of raceme, ovary, and exterior of sepals sparsely furfuraceoas. 8cpals
unequal, rcflexed, the dorsal broadly oblong, its edges towards the apex reflcxcd; tiie
lateral pair larger, oblong, sub-falcate, obtuse, aduato for about a third of their leugth
to the sides of the hp, and for tlie rest connivent under it. Vetáis oblong, bhint. Lip
fleshy, aduato to the base of the column and forming with it a right angle, its anterior
wall cut away iu tho upper part, the apical half conical, its cavity partly occluded by
t,vo largo calli from tlie back and front Avails, the latter sending a septum acro.ss and
dividing the cavity into an upper and a lower charabcr; the latter chambor nectariferous,
the side lobes along the mouth of the spur narrow and inciu-ved; tho apical lobe minute,
narrowly triangular, also incurved. Column short; the rostollum very long, hooked at the
apex, and twisted to one side. AniJicr depressed, beakcid; polHnia four, plauo-convcx,
sub-orbicular, attached by pairs to the long tapoiing slender eaudicle; gland snuill, subrotund.

The flowers of this in Sikldm are white, tlie lip having a large yellow spot in front.
The flowers originally sent to Lindley, and on which he founded his C. obtusa, were
however described by him as of a dull dirty rose colour. It is therefore possible that
the reduction of that species to tliis is incorrect.

2. CAMAEOTIS MAMSH, King and Pantling.
Stem pendulous, slender, 8 to 12 in. long, leafy, sometimes branched, clothed
with the ridged siieaths of fallen leaves. Leaves coriaceous, Huear, acute and very
minutely bifid at tho apex, 3 or 4 in. long, and 3 or 4 in. broad, liacomes straight, rigid,
shorter than the leaves, extra-axillary; the peduncle very short, stout like the racliis.
Flowers not crowded, about -25 in. iu diani.; Iract membranous, oblong, acute, one-third
the length of the sessile scurfy ovary. Sepals and petals sub-equal, obovate, narrowed at
the base, the petals slightly falcate, all rcflexed. Lip an elongated sac at right angles
to the ovary, adnato to tho column, its anterior wall cut away at a right angle iu
the upper half; the edges of the month with two minute, oblong, obliquely trancate,
crcct side lobes, and between them a minute broad shallow triangular apical lobe ; the
margins of all tho lobes slightly incm-ved; tho apical lobe with a flat callus or scale
imniediatoly witliin it and projecting into the cavity of the spur ; the posterior wall
of the interior of the spur- with a raised ridge, hut forming no real septum. Column
short, stout, twisted; the rostellum sigmoid and beak-like. Anther depressed; pollinia fom-,
jilano-couTcx, attached by paii-s to tho long tapering caudicle ; gland small, oblong.
