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 (/. 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 8yg). 



Phoradendron chaguaramasanum Trelease sp. nov. 



Scarcely forked, the moderate branches with basal cataphyls 

 only, androgynous?. Internodes short (2 X 10-30 mm.), at first 

 papillately roughened, quadrangular and somewhat 4-winged, little 

 flattened. Cataphyls a single pair, nearly basal, deeply notched. 

 Leaves spatulate-oblong, obtuse to subtruncate, scarcely 1 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-fiowered 

 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
