beneath along the veins and short-pilose elsewhere, the veins promi- 

 nent beneath, bearing a few short weak spines, the terminal leaflet 

 rarely somewhat lobed, on a petiolule 5-14 mm. long, the lateral 

 leaflets sessile, those of the upper pair smaller than those of the 

 lower pair; flowering branches axillary and terminal, 1-3-flowered, 

 the bracts 3-foliolate, the peduncles 2-2.5 cm. long, glandular-setose ; 

 sepals ovate, 1.5-2.5 cm. long, 6-8 mm. wide, long-acuminate or 

 attenuate to a subulate tip, densely glandular-setose outside and 

 armed with numerous slender spines, short-pilose within ; petals 

 not seen ; fruit not more than half as long as the sepals, the drupes 

 numerous, apparently dry, puberulent above, tomentose at the base, 

 the pyrenes 3-4 mm. long, rugose. 



Type in the U. S. National Herbarium, no. 631482, 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. 1431). 



The plant is related to Rtibits mauensis Engler, described from 

 Mau Mountain, not far from Mount Kenia. That species differs 

 in its trifoliolate leaves, with leaflets about as broad as long, and 

 in its narrower sepals.
