Rubiaceae here described as new. The two new species of Urceolaria 
are of special interest, since this genus is a very small one, and only 
two species have been known hitherto to occur in the West Indies. 
Evea tontaneoides Britton & Standl., sp. nov. 
Plants herbaceous, the stems slender (1 to 1.5 mm. thick), ascending or 
decumbent, densely pilose with slender whitish spreading multicellular hairs; 
stipule sheath greenish, 2 to 3 mm. long, densely pilose, the lobes two on 
each side, lance-linear, 3 to 4 mm. long, long-ciliate, pilose on the outer sur- 
face; petioles slender, 4 to 6 mm. long, densely pilose; leaf blades lanceolate, 
lance-oblong, or oblong-ovate, 3 to 6 em. long, 1.5 to 2.5 em. wide, acute or 
acuminate, rounded and often unequal at base, thin, above deep green, pilose 
with long, slender, apparently appressed hairs, beneath pale and similarly 
pilose; peduncles solitary in the forks of the branches, slender, densely pilose, 
about 3 em. long, the flowers few, sessile in a dense head; bracts obovate or 
spatulate, 4 to 6 mm. long, acute or apiculate, green, sparsely pilose; calyx 
lobes linear, green, pilose; corolla (in bud) villosulous. 
Type in the Herbarium of the Trinidad Botanic Garden, collected at 
Caparo, Trinidad, October 26, 1916, by W. E. Broadway (no. 9774). 
A well-marked species, in habit strongly suggesting certain plants of the 
genus Tontanea, of the same family. 
Urceolaria clusiaefolia Britton & Standl., sp. nov. 
Branches stout, brown, angulate, somewhat lustrous, the internodes 2 to 8 
em. long; stipules quickly deciduous; petioles stout, 1 to 1.5 em. long, 
glabrous; leaf blades oblong-obovate to obovate-elliptic, 8 to 11 em. long, 
3.5 to 5.5 em. wide, acute, often somewhat abruptly so, at base acute or 
acuminate and decurrent upon the petiole, coriaceous, glabrous, lustrous 
above, the costa shallowly channeled, the lateral nerves evident and slightly 
elevated, beneath brownish, the costa and lateral nerves prominent, the 
latter about 8 pairs, ascending at an acute angle, anastomosing to form a 
continuous nerve remote from the margin, the ultimate nerves prominulous 
and irregularly reticulate; peduncle over 1.5 em. long, stout, the involucre 
entire, about 3 mm. long; calyx spathaceous, in fruit about 1 cm. long, the 
immature fruit 5 to 6 mm. in diameter. 
Type in the Herbarium of the Trindad Botanic Garden, collected on 
Mt. Tocuche, Trinidad, August, 1847, Botanic Garden Herbarium 673. 
Although only imperfect specimens are available for study, these differ 
so conspicuously in leaf characters from the other West Indian representatives 
of the genus that it seems safe to assume that they represent a distinct species. 
Urceolaria angustifolia Britton & Standl., sp. nov. 
Branches stout, angulate, glabrous, brownish, the internodes 1 to 3 em. 
long; stipules caducous; petioles 6 to 10 mm. long; leaf blades oblong- 
oblanceolate or narrowly oblong, 4.5 to 8 em. long, 1.2 to 2.5 em. wide, obtuse, 
cuneate at base, coriaceous, glabrous, lustrous above, the costa shallowly 
channeled, the lateral nerves evident and slightly elevated, beneath brownish, 
the costa and lateral nerves prominent, the latter about 11 pairs, ascending 
at a very acute angle, curving outward and anastomosing remote from the
