sis; corollae laciniis majoribus, extus densius strigillosis ;

sissime hirsutis differt. Capsula globosa, coriacea, 2mm. 
in diametro, in fructu calycis laciniis usque ad 1.5 mm.

A study of the original description of Rondeletia rupi- 
cola and an examination of a duplicate type (Spruce 3392) 
preserved at the Gray Herbarium and a photograph of 
the Spruce specimen at Berlin indicate that there are a 
number of minor variations which serve to separate the 
new variety described above. The capsule of Rondeletia 
rupicola is unknown, but the type of var. chiribiquetana 
has both flowers and fruit. The color of the flowers of 
Rondeletia rupicola is not designated; that of var. chiri- 
biquetana is pink. 
Cotomsia: Comisaria del Vaupés, Macaya-Ajaju River confluence, 
Mount Chiribiquete, quartzite base, summit 800-1200 feet above 
forest floor, 1700-2100 feet above sea level. ‘‘Flowers rose-pink. 
Leaves dark green above, pale below. Hair silvery. Shrub.’’ May 
15-16, 1943, Richard Evans Schultes 5448 (Tyrr in Herb. Gray).
