veins prominent beneath, the midvein armed with few or numerous 

 short Stout recurved spines; panicles few-flowered, 8-10 cm. long, 

 the bracts lanceolate and entire or trilobate; pedicels 1-2 cm. long, 

 densely pilose, armed with short slender recurved spines ; sepals 

 oblong, oval, or obovate, i cm. long, abruptly cuspidate, the tip 

 1-2 mm. long, densely sericeous-pilose on both surfaces with fulvous 

 hairs ; petals suborbicular, 12-14 mm. long, white, rounded and 

 crenate at the apex ; fruit about i cm. in diameter, the drupes 

 numerous, dry or nearly so, short-pilose; pyrenes 3-3.5 mm. long,

Type in the U. S. National Herbarium, no. 632297, collected on 

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

 bamboo zone, altitude about 3,000 meters, September 28 to Octo- 

 ber 7, 1909, by E. A. Mearns (no. 2325). This specimen is in fruit, 

 but a flowering branch of the same collection is mounted on sheet 

 632296. Here also belongs no. 1791, from the lower border of the 

 bamboo zone, collected October 8 to 13. 



The proposed species is related to Riibus petitiamis A. Rich., a 

 plant of the mountains of Abyssinia, which is distinguished by its 

 much less pubescent leaves and very difi^erently shaped sepals. It 

 seems to agree with none of the other species described in recent 

 years from the highlands of eastern tropical Africa.
