3G0 CXXTT. OEClTTDACEiE. 



Plants with tlie habit of Dlsa ; differing in the petals and labelh 



The genus consists, at present, of 3 species, of which the two first known 

 were discovered by Eev. J. Brownlee, in Caffraria. Flowers sky-blue 

 pinkish or white. 



27. MONADENIA, Liudl. 



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 

 resupiuate, the eaudieles united to a single gland. — Liiidl. Orch. 

 p. 356. 



Plants with tlie habit of the leafy Disas, with dull-coloured, brownish- 

 purple, greenish or yellowish flowers. — There are several species, dispersed 

 tlirough 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 t-^asted, 

 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. 

 Eostellum 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. 3G0 ; Harv. 

 Tkes. t. 84. 



Herbs, of small size, resembling the leafy Disce, with numerous narrow, 

 cliannelled 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.
