apparently an element peculiar to the sandstone moun- 
tains of the Venezuela-Guiana land-mass. It is especially 
abundant on the sun-baked summit of Cerro Ee-ree-ee- 
k6-mee-6-kee, where the habit photograph published 
herewith was taken. 
Cotompia: Comisaria del Vaupés, Rio Piraparand, Raudal M6-k6, 
Cerro Ee-ree-ee-ké-mee-6-kee. “‘Flowers deep red, covered with grey 
pulverulence. Fruit dark green. Inflorescence up to 10 feet tall. On 
bare rock. Leaves yellow inside at base, rest green.’’ September 18, 
1952, Richard Evans Schultes & Isidoro Cabrera 17532. 
Brocchinia acuminata L. B. Smith in Brittonia 3 
(1939) 160, f. 3 a-d. 
This species was described originally from Mount 
Auyan-tepui in southeastern Venezuela. Steyermark ex- 
tended its known range in Venezuela eastward to Ptari- 
tepui, and Maguire westward to Cerro Guaiquinima, 
while the collections noted below record its appearance 
in Colombia making a total range of over 700 miles.

Brocchinia hechtioides Mez in Fedde Repert. Sp. 
Nov. 12 (1918) 414. 
One of the dominant species on the sandstone top of 
Cerro Isibukuri, Brocchinia hechtioides is characteristic 
of the quartzitic mountains of the Venezuela-Guiana 
land-mass. Because of its characteristic place in the ecol- 
ogy of these mountain-tops, it seems advisable to pub- 
lish the accompanying habit photograph.
