Ficus panamensis is similar in most characters to F. hemsleyana (see p. 29), but is 
distinguished by its sessile or nearly sessile receptacles. The leaf blades, too, are 
narrower and have a longer, narrower acumen. 
17. Ficus williamsii Standley, sp. nov. 
Small tree; branches grayish, the young ones stout, puberulent, becoming glabrate; 
stipules triangular-oblong, 13 mm. long, thin, dark brown, strigose outside with stiff 
fulvous hairs; petioles stout, 1.5 to 2 cm. long, pruinose; leaf blades oblong or elliptic- 
oblong, 10 to 14 cm. long, 5.3 to 6.3 cm. wide, slightly narrowed toward both ends, 
obtuse at the base, subemarginate and 3-nerved, obtuse at the apex and acutely 
short-apiculate, coriaceous, glabrous, lustrous on the upper surface, the lateral veins 
prominent beneath, 9 or 10 on each side, distant, divergent at an angle of 60 degrees, 
straight, laxly and arcuately anastomosing near the margin, the veinlets obscure; re- 
ceptacles geminate, sessile, subglobose (very immature in specimen), 12 to 14 mm. 
in diameter, densely and minutely grayish-puberulent, the ostiole not prominent, 
triangular, 2.5mm. broad; involucre bilobate, 11 mm. broad, the lobes rounded, thin, 
brown, pruinose-puberulent; sepals ferruginous. 
Type in the U. S. National Herbarium, no. 678105, collected in the vicinity of 
Penonomé, Panama, February or March, 1908, by R. S. Williams (no. 404). 
In leaf texture this resembles Ficus goldmanii, but that has proportionally narrower 
leaves and different receptacles, which are borne on long peduncles. 
18. Ficus inamoena Standley, sp. nov. 
Older branches brownish gray, the young ones pale brownish, hirtellous with whitish 
hairs; stipules broadly triangular, 5 to 7 mm. long, acute, ferruginous, puberulent 
and sparsely strigose on the outer surface; petioles stout, 8 to 15 mm. long, hirtellous, 
deeply canaliculate; leaf blades rounded-oval, broadest slightly above the middle, 
6 to9 cm. long, 4.5 to 6.5 cm. wide, deeply cordate at the base, the sinus very narrow 
or the lobes slightly overlapping, broadly rounded at the apex and sometimes sub- 
emarginate, coriaceous, grayish green, short-hirtellous on both surfaces and velvety to 
the touch, the lateral veins prominent on both surfaces, 5 or 6 on each side, distant, 
divergent-ascending, slightly arcuate, laxly anastomosing near the margin, the costa 
anastomosing below the apex with the lateral veins, the veinlets very conspicuous, 
coarsely reticulate; receptacles geminate, sessile, depressed-globose, 10 to 11 mm. 
broad, glabrous, the ostiole not elevated, 2 mm. broad, closed by 2 truncate scales; 
involucre bilobate, the lobes rounded, pilose-strigose; sepals ferruginous. 
Type in the U. 8. National Herbarium, no. 860244, collected at Joyabaj (El Quiché), 
Guatemala, May 11, 1906, by O. F. Cook (no. 22). 
Related to Ficus cotinifolia, but amply distinct in the deeply cordate leaf blades 
and small involucres. From F. kellermanii it is distinguished by the deeply cordate, 
broader, more pubescent leaf blades. 
19. Ficus colubrinae Standley, sp. nov. 
Older branches grayish or light brown, the young ones stout or often slender, densely 
pilose-strigose with long sordid hairs, tardily glabrate; stipules narrowly triangular, 
5 to 8 mm. long, long-acuminate, densely pilose-strigose outside, or glabrate above, 
thin, ferruginous; petioles stout, 8 to 24 mm. long, densely pilose-strigose; leaf blades
