to F. crassinervia of Hispaniola, to which species it has been 
referred, and also related to F. Urbaniana Warburg, of the Lesser 
Antilles. 
Ficus arimensis sp. nov. 
Twigs stout. Leaf-blades firm in texture, obovate, about 2 
dm. long and twice as long as wide, distantly pinnately veined, 
the base subcuneate, the apex rounded and short-cuspidate; fruit 
subglobose, sessile, about 8 mm. in diameter (immature). 
Arima, Trinidad (J. Dannouse). Collected in 1905. 
Ficus Mendelsonii sp. nov. 
A tree up to 16 m. high. Leaves elliptic to obovate-elliptic, 
the blade thin, smooth, 10-15 cm. long, about twice as long as 
wide, distantly pinnately veined, triple-veined just above the base, 
the base rounded or obtuse, the apex abruptly short-acuminate; 
petioles slender, 2-6 cm. long; peduncles slender, 1-2 cm. long; 
fruit globose, pale, 10-15 mm. in diameter, the ostiolum deeply 
concave; basal bracts 2, triangular-ovate, about 2 mm. long. 
Forests in moist or wet districts, Trinidad. Type from the 
northern hills between North Post and Maqueripe (Britton, Hazen 
and Mendelson 879). 
Phoradendron chaguaramasanum Trelease sp. nov. 
Scarcely forked, the moderate branches with basal cataphyls 
only, androgynous?. Internodes short (2 KX 10-30 mm.), at 
papillately roughened, quadrangular and somewhat 4-winged, little 
flattened. Cataphyls a single pair, nearly basal, deeply notched. 
Leaves spatulate-oblong, obtuse to subtruncate, scarcely I X 2.5 
cm., cuneately subpetioled for 5 mm., fleshy, drying yellow, I- or 
obscurely 3-nerved from the base. Spikes solitary, very short 
(about 5 mm.), with 2 or 3 very short characteristically 4-flowered 
joints; peduncle about 1 mm. long; scales ciliolate. Immature 
fruit subglobose, scarcely 2 mm. in diameter, reddish, verrucose; 
sepals yellow, erect, not meeting. 
Chaguaramas, Trinidad (Britton 2718, the type, April 4, 1921). 
Phoradendron caerulescens Trelease sp. nov. 
Pseudodichotomous, the moderate branches with basal cata- 
phyls only, androgynous?. Internodes short (2-3 X 10-20 mm.), 
smooth, glossy, quadrate, the upper ancipitally dilated to a width 
of 4 mm. below the nodes. Cataphyls a single pair, basal, glossy 
brown, tubular-bifid. Leaves round-elliptical, submucronately
