Hydrocotyle Hazenii Rose sp. nov. 



A delicate creeping plant, rooting at the nodes; petioles slender, 

 2 to 5 cm. long, pubescent and more pronounced just below the 

 blade; blade nearly orbicular, 2.5 cm. in diameter or less, glabrous 

 and paler beneath, somewhat hairy or glabrate above, the sinus 

 usually narrow, the margins doubly crenate, the crenations low 

 and broad; peduncle slender, hairy above, longer than the petiole; 

 flowers in a small compact umbel ; pedicels I to 2 mm. long. 



Among wet rocks, Maracas Waterfall, Trinidad (Britton, Hazen 

 and Mendelson 1660, April 10, 1920). 



Psammisia recurvata sp. nov. 



Stems branched, about 5 m. long. Leaves coriaceous, glabrous, 

 elliptic-ovate, 10-20 cm. long, 7-10 cm. wide, pinnately 7-veined 

 from near the base, with numerous curved transverse veinlets, the 

 venation impressed above, prominent beneath, the apex acute, 

 the base narrowed, the stout petiole 1-2 cm. long; flowers several 

 in short axillary racemes; bractlets ovate, acute, about 2 mm. long; 

 pedicels stout, recurved, glabrous, 2-3 cm. long; ovary subglobose, 

 glabrous; calyx subcampanulate, persistent, about 6 mm. long in 

 fruit, its lobes rounded, apiculate, their margins thickened; corolla- 

 tube about 4 cm. long, red, the short limb white; fruit globose, 

 about 1 cm. in diameter, many-seeded. 



Forest bank, near summit of Mount Tocuche, Trinidad 

 (Britton, Hazen and Mendelson 12Q4). 



Specimens of this plant were mixed by Grisebach with those 

 of another and the complex described by him (Fl. Br. W. I. 143) 

 as Thibaudia latifolia Griseb., subsequently referred by Bentham 

 and Hooker to Vaccinium; it would appear that the name latifolia 

 should go with this other species, which, however, is not a good 

 Vaccinium. 



Sophoclesia trinitensis sp. nov. 



Pendent from forest trees; stem slender, sparingly branched, 

 short-villous when young, 1-4 m. long. Leaves subcoriaceous, 

 glabrous or nearly so, ovate or some of them ovate-lanceolate, 1.5- 

 3.5 cm. long, from about one half to two thirds as wide as long, 

 triplinerved with a pair of delicate veins at the base, this venation 

 rather distinct beneath, obscure above, the apex bluntly pointed, 

 the base rounded or subtruncate, the villous petiole about 2 mm. 

 long; peduncles filiform, glabrous, somewhat shorter than the 

 leaves; ovary globose, glabrous or with a few hairs; corolla white,
