One of the most common riverine lianas in Amazonian 
Colombia, Combretum rotundifolium has not been fre- 
quently collected there; Schultes 3984 is apparently but 
the second collection reported in the literature. The first 
(Schultes in Bot. Mus. Leafl. Harvard Univ. 14 (1950) 
135) was from the distant Apaporis River basin. 
Cotoms1A: Comisaria del Amazonas, Rio Igaraparana, between Que-

Combretum Wandurraganum P. I. Schultes sp. 
nov. 
Frutex scandens, extensus, robusto cum trunco et 
ramis glabris laevibus teretibusque et ramulis fusco- 
lepidotis. Folia chartacea, elliptica vel subovata, apice 
abrupte acuminata, basi rotundata, integra, statu adulto 
7-17 cm. longa, 4-8 cm. lata, supra nitidula, subtus vivo 
aureo-lepidota, venis secundariis plerumque novem sub- 
tus aliquid conspicuis. Paniculae axillares, apparenter 
densiflorae, plerumque usque ad 24 cm. longae, rhachidi- 
bus robustioribus 4 mm. in diametro, dense fusco-lepi- 
dotis. Flores adhuc ignoti. Samarae pulchrae, atrosan- 
guineae, quadrialatae, orbiculares, plerumque 2.2-—2.4 
em. latae (alis computatis), plusminusve 2—2.2 cm. altae, 
longe et graciliter stipitatae (stipitibus 10-12 mm. longis, 
dense lepidotis), omnino sparsissime lepidotae. 
Combretum Wandurraganum resembles most closely 
perhaps C. rotundifolium Rich., from which it can be 
distinguished by differences in the size and shape of the
