460 BULLETIN OF THE TORREY CLUB [vol. 53 



There are only a few species of Torrubia that have pubescent 

 foliage. The present plant is related to T. cuspidata, of Grenada 

 and Trinidad, hut differs conspicuously in leaf characters. 



Tounatea cubensis Britton & Wilson, sp. nov. 



A small tree, the young twigs, petioles, and rachis more or 

 less densely pubescent with dark brown hairs. Leaves odd- 

 pinnate, 1.5-2.6 dm. long, the leaflets 13 or 15, elliptic-lanceolate 

 to elliptic-oblanceolate, 5-9.5 cm. long, 2-3 cm. broad, short- 

 petioled, the base obtuse, the apex acuminate, finely reticulate- 

 veined on both surfaces; pod ellipsoid, about 4.6 cm. long. 



Valley of the San Juan, Pinar del Rio, Cuba {J. T. Roigji62 y 

 April 5, 1924, foliage, type; fruit sent by Dr. Roig from Pinar del 

 Rio, June 1925). This is the first record of the genus Tounatea 

 in Cuba. In leaf form it approaches Tounatea caribaea (Griseb.) 

 Taub. of the Lesser Antilles. 



Bunchosia linearifolia P. Wilson, sp. nov. 



Shrub about 3 m. tall, with grayish branches. Leaves linear 

 or somewhat linear-obovate, 3-6 cm. long, 2.5-5 mm - wide, 

 rounded at the apex, acute at the base, lustrous above, dull and 

 faintly nerved beneath, the petioles 2-3 mm. long; drupes sub- 

 globose, 10-12 mm. in diameter, apiculate. 



Type collected in thickets between Jauco and Cajobabo, 

 Oriente, Cuba {Brother Leon 12062). Related to Bunchosia 

 Leonis Britton & Wilson, of Cuba, but differing in its linear- 

 obovate leaves. 



Byrsonima motembensis Britton & Small, sp. nov. 



A shrub 2 m. tall or less, with warty-rugose gray bark and 

 red-strigillose twigs. Leaves mainly on the twigs, early de- 

 ciduous from the branches, the blades cuneate to obovate- 

 cuneate, 2-6 cm. long, obtuse or abruptly short-pointed, gray- 

 ish-green, somewhat lustrous and with minute scattered hairs 

 above, paler, dull, somewhat reticulate, and with minute scat- 

 tered hairs beneath, at least during anthesis, short-petioled, the 

 petioles hairy like the twigs when young; panicles raceme-like, 

 peduncled, rather few-flowered, the peduncle and pedicels pu- 

 bescent like the twigs, but the hairs often early deciduous from 

 the peduncle; bracts shorter than the pedicels, lanceolate; sepals 

 ovate to orbicular-ovate, 2>~3-S mrn - l n g 5 obtuse, red-pubescent, 

 corolla 12-15 mrn - wide; petals 7-9 mm. long, with orbicular- 

 reniform claws, the blade of one smaller and the claw stouter than 

 in the others; filaments clavate, 2-2.5 mm - long; anthers fullv
