Hardly distinguishable from D. depressa (cf. Schinz in Bull. Herb. Boiss. iv. 846) ; 

 the plant is taller, attaining 3-4 ft., with straight branches and very erect fruit 

 clusters ; the main branches have leaves 2 in. and more long ; but the branchlets with 

 shorter leaves by themselves might pass for D. depressa. 



o. D. radicans, Nees in DC. Prod. xi. 106. Stems procumbent, 

 branching, rooting, hispid-pubescent at the tips (and throughout in hill 

 examples), with no straight simple branches. Leaves not exceeding 

 1 in. in length. Calyx-tube hairy within. Corolla scarcely 2-lipped. 

 Capsules spreading; otherwise as D. depressa. — A. Rich. Tent. Fl.

The East African material agrees well together, varying a little in degree of 

 hairiness ; but its distinctness from D. depressa may be doubted.
