1 . D. kilimandscharicum, C. I>. Clarke. Pubescent small shrub. 

 Leaves f-1 by I in., obovate, obtuse, toothed, microscopically densely 

 dotted, cystoliths obscure ; petiole hardly any. Flowers clustered, in 

 ancillary small cymes ; bracteoles lanceolate, h the length of the calyx. 

 Calyx \ in. long, divided J way down, with many cystoliths ; tube 

 nearly glabrous within, short-pubescent without ; teeth narrowly linear- 

 lanceolate. Corolla J in. long, somewhat 2-lipped ; lobes contorted in 

 bud, obtuse, hairy without, with many long deflexed hairs in the throat. 

 Stamens 4 ; filaments with long white hairs below, and a few stalked 

 glands upwards ; anthers equal, similar, base not apiculate ; pollen 

 round-ellipsoid, longitudinally several-ribbed. Ovary glabrous ; style 

 hairy, with 2 linear unequal stigmatic branches ; ovule 1 in each cell . 

 Capsule \ in. long, obovoid-ellipsoid, much flattened, hard brown, 

 shining. ^Seeds 2, round, flattened, on large retinacula, covered with 

 tufted long hairs, which spring out elastically on being wetted. —

2. D. quadrisepalum, C. B. Clarke. Pubescent small shrub. 

 Leaves up to If by | in., narrowed at both ends, more or less strongly 

 crenate-toothod ; petiole hardly any. Flowers closely clustered in 

 axillary small cymes ; bracteoles linear-lanceolate, as long as the calyx. 

 Calyx exceeding \ in. in length, 4-fid nearly to the base, 2 anticous 

 segments connate nearly to the tip into 1 obovate-elliptic 2-nerved 

 piece, 3 others nearly equally long. Corolla J in. long. Stamens 4, 

 subsimilar; anthers of 2 equal parallel oblong muticous cells; pollen 

 ellipsoid, many-ribbed. Style thinly hairy ; branches ^2, linear-oblong.

From the 4-fid calyx and the 1-ovulate ovary-cells, this species was referred to 

 Barleria, sect. Somalia. It is very like D. kilimandscharicum.
