Type in the U. S. National Herbarium, no. 631542, collected on 

 the western slopes of Mount Kenia, British East Africa, in the 

 giant heath zone, altitude about 3,630 meters, September 21 to 27, 

 1909, by E. A. Mearns (no. 1487). No. 1426 from the same 

 locality is also this species. 



Related to Bartsia kilimandscharica Engler, which differs in its 

 small leaves and flowers. B. keniensis is a shrub which blackens 

 when dried. The four branches of the specimens are practically 

 simple, but slender, weak, sterile branches are borne in the axils of 

 some of the leaves.
