CXXII. ORCHIDACER. 365 
93. SATYRIDIUM, Lindl. 
Perianth ringent, the lower lip formed by the subsimilar 
sepals and petals ; the upper by the funnel-shaped, 2-spurred, 
acuminate labellum. Column slender, free. Anther straight, 
resupinate, with parallel cells. Stigma minute, truncate, at 
the apex of the column. Caudicles connate, attached to a 
single gland — Lindl. Orch. p. 345 ; Harv. Thes. t. 87. 
A single species, with the habit of Satyrium.—Western district. 
24. AVICEPS, Lindl. 
Perianth ringent, the lower lip 3-toothed, formed of the 3 
cohering sepals; the upper of the helmet-shaped, 2-saccate 
labellum. Petals none. Column terete, elongate, hidden 
under the galea. Stigma 2-lipped, the upper lip very large, 
emarginate ; the lower on each side produced into an arm-like 
process. Anther resupinate. Caudicles nude, lying along the 
arms of stigma; glands nude.—Lindl. Orch. p. 345. 
A small, densely-leafy plant. Flowers axillary, hid among the upper 
leaves. Known from the saccate species of Satyrium by the absence of 
petals— Western districts, rare. 
95. DISA, Linn. 
Perianth ringent, the upper lip formed of the helmet- or 
funnel-shaped, spurred or saccate odd sepal; the lower lip 
formed by the two flat, spreading lateral sepals and the label- 
lum. Petals small, erect, adhering to the base of the column. 
Labellum free, filiform or dilated, entire or multifid, spurless. 
Column 2-parted (the anther and stigma separated). Anther 
2-celled, erect or supine ; with 2 distant, nude glands. Stigma 
truncate or convex, with an obscurely 3-lobed disk, often tu- 
bereular, at the base of the column.—Lindl. Orch. p. 346 ; 
Harv. Thes. t. 41, 85, 86. 
A large genus, dispersed through the colony and in Natal, including the 
finest of the Cape Orchids, as well as some of the humblest. Habit various; 
leaves either all radical or radical and cauline. Flowers mostly spiked, 
rarely solitary. D. grandiflora, the glory of Table Mountain, has flowers 
3-5 inches across. 
26. BROWNLEBEA, Harv. 
Perianth ringent, the upper lip formed of the galeate 
spurred odd sepal, and of the two petals whose inner margins 
adhere to it; lower, of the two spreading, flat, lateral sepals. 
Labellum minute, inflexed, filiform, its base expanded, and ad- 
hering at each side to the column, forming therewith a little 
pocket. Anther ascending, 2-lobed.—Lindl. in Hook. Lond. 
Journ. Bot. i. p. 16; Harv. Phes. t. 103, 104.
