Rio Yamuri, Oriente {7800), tentatively referred to this species, 

 have spatulate leaves 12 cm. long. 



5. Plumiera nipensis sp. nov. 



A slender tree, up to about 6 m. in height. Leaves narrowly 

 oblong, 9-12 cm. long, 1.5-2.3 cm. wide, obtuse at the apex, 

 narrowed at the base, glabrous on both sides, shining above, dull 

 beneath, the midvein channeled above, prominent beneath, the 

 lateral venation widely spreading, impressed, but distinct, above, 

 the rather slender petioles 1 cm. long or less; peduncle stout, 6 cm. 

 long; follicles 13-15 cm. long, about 2 cm. thick, acutish; seeds 

 10 mm. long, 6-7 mm. wide, the wing about 15 mm. long, 8-9 

 mm. wide. 



Rocky thicket, between Piedra Gorda and Woodfred, Sierra 

 Nipe, Oriente, at 500 m. alt. (Shafer 3089). Perhaps the same as 

 P. obtusa laevis Griseb. (Mem. Am. Acad. II. 8: 519) from Monte 

 Verde, Oriente. 



6. Plumiera emarginata Griseb. Cat. PI. Cub. 171. 1866 



Rocky cliffs and hillsides, Matanzas; Pinar del Rio; Isle of 

 Pines. Endemic. 



7. Plumiera obtusa L. Sp. PI. 210. 1753 

 Coastal hills, keys and thickets, Oriente; Camaguey; Santa 

 Clara : Bahamas ; Hispaniola ; Mona. Attributed to Jamaica, but 

 some specimens which have been so referred represent a distinct 

 species.* 



* Plumiera confusa sp. nov. 



A tree, up to 6 m. high, little branched, glabrous throughout. Leaves narrowly 

 elliptic or oblong, shining, 1-3 dm. long, 7 cm. wide or less, obtuse, emarginate or 

 acute at the apex, narrowed at the base, the midvein channeled above, prominent 

 beneath, the lateral venation widely spreading, the stout petioles 4-8 cm. long; 

 peduncles stout, 7-15 cm. long; cymes large, many-flowered; pedicels rather stunt, 

 thickened upward, 9-12 mm. long; calyx nearly truncate, about 3 mm. long; corolla 

 white with a pale yellow eye, its tube 12-15 mm. long, its lobes broadly oblong, 

 rounded, 2.5-3 cm. long, about 1 cm. wide; follicles 8-12 cm. long, 10-12 mm. thick. 



Rocky situations, southern side of Jamaica. Type collected on Great Goat 

 Island {Harris Q309) ; 



The species more resembles P. emarginata than P. obtusa. I am unable to deter- 

 mine, from the material available at this time, whether P. obtusa occurs on Jamaica or 

 not. Other specimens referable to P. confusa are: Healthshire Hills near Salt Island 

 (Britton 3061); base of Healthshire Hills near Salt Ponds (Britton 3036); Great Goat 

 Island (Harris 10 168; Britton 1874). 



The Plumiera of Pedro Bluff, a locality about thirty miles west of Great Goat 

 Island, but still within the xerophytic region, may be P. obtusa, but the specimen
