2. Coccolobis laurifolia Jacq. Hort. Schoen. 3: 9. 1797. 



A tree, up to 20 m. high, with a trunk sometimes 7 m. thick, usually much 

 smaller, and often shrubby, the thin gray bark brown mottled, the twigs and 

 leaves glabrous. Leaves ovate, elliptic or obovate, coriaceous, obtuse or acute 

 at the apex, rounded at the base, 4-12 cm. long, or those of young shoots 

 larger, the petioles 5-20 mm. long, the sheaths short; racemes slender, 5-10 

 cm. long; pedicels 5-8 mm. long; calyx greenish about 5 mm. broad, its lobes 

 suborbicular ; fruits subglobose, red, acid, 8-10 mm. in diameter. 



Scrub-lands and coppices, throughout the archipelago from Abaco and Great 

 Bahama to Caicos and Inagua : Florida ; Cuba to St. Croix ; Jamaica. Very various 

 in size and shape of leaves, the species evidently composed of numerous races, 

 one of which was recorded in Mrs. Northrop's Flora as the Cuban (7. Wrightii 

 Lindau, a different species ; and another as C. tenuifolia L., as also recorded by 

 Dolley and by him also as G. punctata L. PIGEON-PLUM. Catesby, 2 : pi. 9$.

 ovate or obovate-elliptic, obtuse to acutish at the apex, obtuse, somewhat nar- 

 rowed, or subcordate at the inequilateral base, 4-7 cm. long, 5 cm. wide or less, 

 the primary veins 6-8 on each side, minutely but strongly reticulate-nerved on 

 both surfaces, dull, the upper surface bright green, tne lower surface paler; 

 petioles 3-5 mm. long; racemes very slender, numerous, recurved-drooping,

 Eleuthera, Acklin's Island, Watling's Island, Inagua. Endemic. Reported by 

 Lindau and by Mrs. Northrop as C. obtusifolia Jacq. BAHAMA PIGEON-PLUM. 



4. Coccolobis Northropiae Britton, sp. nov.

 glabrous. Leaves orbicular to obovate or obovate-orbicular, 3-5 cm. long, 

 chartaceous or subcoriaceous, obtuse, rounded or acutish at the apex, narrowed 

 or obtuse at the base, retiulate-veined on both sides when old, the petioles 3-6 

 mm. long, the ocreae short; racemes mostly as long as the leaves or longer, 

 the rachis puberulent or glabrous; pedicels '2-3.5 mm. long, solitary or 2 or 3 

 together; perianth about 3 mm. long; ocreolae obliquely truncate, about 1 mm. 

 long; fruit ovoid, about 5 mm. long, short-coronate, the exocarp fleshy.
