 more or less orbicular, varying in size, 2.5-6 cm in diameter; cotyledons orbicu-

Material with flowers past anthesis and matured fruits is available. As far 

 as can be seen in the absence of flowers, the plant differs from .1. neblincu 

 chiefly in the persistent grey tomentum which forms a close hoary covering on 

 the under side of the leaves. The fruits are not thickly velutinous as in .1. 

 neblinae, but only minutely tomentulose; their lightly roughened surface is ex- 

 posed. The seeds are more or less similar to those of A. neblinae, generally oval- 

 orbicular but varying to triangular, about 5 cm long, 3.5-4 cm. wide; cotyledons 

 orbicular, about 1.7 cm in diameter, cordate at the base with closed sinus ; radicle 

 3 mm long, not surpassing the cotyledon-lobes. The calyx (past anthesis) is 

 about 3 mm broad at the base, the lobes about 3.3 mm long. The leaf-blades are 

 (6-) 7-16 em long and 3.5-7 cm wide. The vegetative indumentum is similar 

 to that of A. spruceanum Benth. and A. fendleri Woods., but the hairs average 

 twice as long. The leaves are more strongly obovate, the broadest part being 

 further toward the summit; the apex is emarginate Or rounded, only rarely with 

 the slightest indication of an acumen.

Our first Venezuelan representative of the genus Condylocarpon connects ('. 

 It iridium w ith C. pubifiorum Muell.-Arg. Isotypes of both are a't The New York 

 Botanical Garden (Esperanca and "prope Barra," respectively). The two seem 

 to differ principally in the character of the indumentum. C. hirtellum is more 

 densely pubescent, the hairs on the stem spreading instead of appressed, the 

 leaves subrounded at base instead of obtusely cuneate, the petiole slightly shorter, 

 about 5 nun long instead of 8 mm. The Rio Yatua specimen has the hairs on the
