100 ORCHIDS OF THE CAPE PENINSULA. 
Sus-trre 1. HABENARIE AS. — Anther erect. Glands of the 
pollinia nude, or more rarely half-included in the channelled or inflexed 
lobes of the rostellum. 
3. Barrnotina.—Sepals herbaceous, small. Petals narrow, erect. 
Lip spreading, large, deeply cut or fringed, spurred at base. 
Anther distant from the stigma; glands of the pollinia 2. 
Rostellum obsolete. 
4. Horoturix.—Flowers small. Sepals herbaceous. Petals longer 
than the sepals, narrow. Lip small, concave or involute, 
variously divided, spurred at base. Gland of the pollinia 1, 
or 2. Rostellum nearly obsolete. 
Sup-triseE 2. DISH A‘.—Anther reclined, or reflexed on the back 
of the column, more rarely sub-erect. Stigma large, pseudo-terminal, 
or distant from the anther and subadnate to the lip. 
5. Saryrtum.—Lip posticous, erect, fornicate or galeate, 2-spurred 
or 2-saccate at base. Anther anticous. Caudicles of the 
pollinia terminating in two glands, or rarely (in one 
species) in a single gland. Stigma pseudo-terminal. 
6. D1sa.—Odd sepal usually posticous, more rarely anticous, 
galeate, fornicate, or nearly flat, 1-spurred, 1-saccate, or 
umbonate towards the base. Lip usually smaller than the 
sepals, variously shaped, but never galeate or fornicate, 
muticous at base. Caudicles of the pollinia terminating in 
one or in two distinct glands. Stigma separate from the 
anther, lying immediately above the ovary. 
Sus-tre 8. CORYCIEA.—Odd sepal posticous, more rarely 
anticous, cohering with the petals into a single galeate, hooded, 
fornicate, or explanate piece. Lip adnate to the face of the column, 
usually produced above the junction into a variously-shaped appendage. 
Cells of the anther usually distant, less commonly (in Disperis only) 
approximate. Stigma bilobed or bipartite, the lobes separated by the 
intervening adnate lip; or stigmas 2, distant. 
7. Disprris.—Side sepals free, spurred or saceate. Lip appendi- 
culate. Rostellum produced into cartilaginous arms in 
front. Anther ascending, the cells approximate. Stigma 
usually situate on the front face of the column, bilobed, the 
lobes approximate ; or stigmas two, lateral and distant. 
8. Corycrum.—F lowers contracted, somewhat small. Side sepals 
connate into an anticous lower lip. Lip appendiculate. 
Stigma posticous, lunate, or bilobed; or stigmas two, lateral 
and distant. Flowers in dense spikes.
