Himatanthus bracteata (4.DC.) Woodson in 
Ann. Missouri Bot. Gard. 25 (1937) 200. 
Known from British Guiana and several stations in 
the Amazon of Brazil (where it is apparently most abun- 
dant in the Rio Negro basin) as well as from Pernam- 
buco and Bahia, Himatanthus bracteata has hitherto not 
been reported from Colombia. Schultes 5814, tentatively 
determined as representing this species, has, according to 
Woodson, leaves which ‘‘are larger than usual.’’ In the 
Vaupés, the plant is known as platanote, due to the 
superficial resemblance of the fruit to the banana. 
Cotomsia: Comisaria del Vaupés, Cerro Chiribiquete. ‘‘Flowers

Vaupés, Rio Vaupés, Cafio Pact (below Cerro Circasia). ‘‘Small tree 
up to 15 feet tall. Latex abundant, white. Platanote.’’ March 6,

Mandevilla nerioides Woodson in Ann. Missouri 
Bot. Gard. 28 (1941) 274. 
Mandevilla nerioides is known only from the Inten- 
dencia del Meta and the Comisaria del Vaupés in Colom- 
bia. The type collection was made on the Guaviare River 
at San José del Guaviare by Cuatrecasas. The following 
collections establish the occurrence of this endemic spe- 
cies on the summit of the remnant quartzite hills of the 
upper Apaporis River which have, in common with the 
hills at San José del Guaviare, a number of. striking 
endemic elements. 
CotomB1a: Comisaria del Vaupés, Cerro Chiribiquete. ““Vine. Flow- 
ers pink. Latex white, sticky.’’ May 15-16, 1943, Richard Evans 
Schultes 5442.—Same locality. “*Vine. Flowers pinkish white. Latex 
white.’’ January, 1944, Richard Evans Schultes 5740.
