366 CXXII. ORCHIDACER. 
Plants with the habit of Disa; differmg in the petals and labellum. 
The genus consists, at present, of 3 species, of which the two first known 
were discovered by Rey. J. Brownlee, in Caffraria. Flowers sky-blue 
pinkish or white. 
27. MONADENTA, Lindl. 
Perianth ringent, as in Disa. Petals fleshy. Labellum 
free, oblong, fleshy, flat. Column small, 2-parted. Stigma 
fleshy, raised, truncate, at the base of the labellum. Anther 
resupinate, the caudicles united to a single gland.— Lindl. Orch. 
p. 356. 
Plants with the habit of the leafy Disas, with dull-coloured, brownish- 
purple, greenish or yellowish flowers.—There are several species, dispersed 
through the colony. 
28. SCHIZODIUM, Lindl. 
Perianth ringent, the upper lip formed of the galeate and 
spurred back sepal, and the petals ; the lower, of the spreading, 
channelled, lateral sepals and the labellum. Petals small, 
fleshy at the apex, unequally 2-lobed or obliquely twisted, 
often eared at base, attached to the column. Labellum free, 
either linear-acuminate, equalling the sepals, constricted above 
the base, or broad and more or less undulated on the surface. 
Column 2-parted. Stigma fleshy, raised, truncate or hollow 
at the base of the labellum. Anther resupinate or horizontal. 
Rostellum with either truncate or acuminate, twisted arms. 
Pollen-glands 2, nude.—Lindl. Orch. p. 358. 
Small plants. Leaves radical, ovate or obovate, spreading, petioled. 
Stem rigid, mostly flexuous, sheathing at the bendings. Raceme few- 
flowered or flowers solitary. Flowers yellow or pink, the labellum often 
spotted.—Several species, in the Western district. 
29. PENTHEA, Lindl. 
Perianth as in Disa, except the back sepal spurless, either 
flattish or hooded. Petals unlike the sepals, mostly fleshy, 
attached to the base of the column, converging over the an- 
ther. Labellum linear or filiform, simple, free, much narrower 
than the petals, separated by a mostly 3-lobed stigma from the 
column. Anther terminal, erect or reclinate, with parallel 
cells, produced and often divergent at base, lying on the stig- 
matic arms. Glands 2, nude.—Lindl. Orch. p. 360; Harv. 
Thes. t. 84: P 
Herbs, of small size, resembling the leafy Dise, with numerous narrow, 
channelled or very slender leaves, and corymbose, spiked or solitary, yellow 
white or mottled flowers. — Several species, in the Western districts, 
Scarcely generically different from Disa.
