5-6 mm. long, 3 nun. broad, acute or acuminate, membranaceous,

 slender, i-flowered, the bracts lanceolate, 2.5-3 ^^- long; pedicels 

 minutely viscid-puberulent ; sepals narrowly oblong or lance-oblong, 

 6-7 mm. long, acuminate, mucronate, densely and minutely puberu- 

 lent and sparsely short-pilose, the mucro i mm. long ; petals broadly 

 obovate, purplish, 8 mm. long; fruit (immature) 15 mm. long, the 

 beak short-hirtellous and puberulent, the valves hirsute. 



Type in the U. S. National Herbarium, no. 631573, collected on 

 the western slopes of Mount Kenia, along the trail from West 

 Kenia Forest Station to summit, in the giant heath zone, British 

 East Africa, altitude about 3,630 meters, September 21 to 27, 1909, 

 by E. A. Mearns (no. 1513). 



The proposed species is doubtless most closely related to Geranimn 

 siniense Hochst. That species, however, is clearly distinguished by 

 its very different pubescence, which is composed of long, slender, 

 reflexed hairs, without any trace of the minute puberulent pubes- 

 cence characteristic of G. keniense. There is a difference also in 

 leaf outline, the blades in G. simense being more deeply lobed and 

 uniformly with 5 divisions.
