47. ANISOTES, Nees; Benth. et Hook. f. Gen. PI. ii. 1111. 



Sepals 5, nearly free, subequal, linear-triangular, 3-nerved. Corolla 

 2-lipped, red ; tube short ; lips very long, entire or minutely lobed, 

 narrow-oblong. Stamens 2 ; filaments long, glabrous ; anther-cells 2, 

 linear-oblong, minutely white-tipped (not tailed) at the base, one a 

 little below the other ; pollen ellipsoid, 2-banded, with one or two rows 

 of marks or tubercles on each side of the stopples. Pistil glabrous ; 

 ovules 2 in each cell; stigma subentire. Capsule (only known in .4. 

 diversifolius) oblong, 4-seeded, stalk cylindric, placentse not rising 

 elastically from the base of valves ; seeds scabrous, almost tubercular on 

 the margins. — Shrubs. Leaves entire. Flowers sessile, axillary clustered, 

 or in dense spikes ; bracts very small, shorter than the calyx. 



Species 5, in Africa and Arabia. 



The corolla is exceedingly like that of Macrornnr/ia, as are the stamens, pollen and 

 pistil. Further, the capsule being unknown in 4 out of 5 species, the placing these 

 species in Anisotes would appear provisional merely. But the peculiar, 3-nerved, 

 elongate-triangular sepals, much longer than the bracts, leave little doubt that the 

 5 species are congeneric.
