14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 68 



Type in the U. S. National Herbarium, no. 631392, collected on 

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

 giant heath zone, altitude 3,630 meters, September 21 to 27, 1909, by 

 E. A. Mearns (no. 1343). No. 1321 from the same locality also is 

 this plant. Two other collections belong here: no. 1214 from the 

 vicinity of Fort Hall, altitude 1,200 meters; and no. 1992, collected 

 on the trail from Nyeri to Wambugu, altitude 1,500 to 1,800 

 meters. In view of the remarkable altitudinal range it may be that 

 the specimens purporting to come from Mount Kenia are really 

 from some other locality. 



The proposed species seems to be near Achyrosperiiiitin parvi- 

 florum S. Moore, but that has different pubescence and short 

 racemes. It is said, also, to have red corollas, while in A. mcarnsii 

 these seem to be white.
