terior scale, linear-acuminate, as long as the narrow part of the corolla-tube ; corolla yel- 

 low : campanulate part of the tube thrice as long as its cylindrical base, little longer than its 

 broadly ovate lobes ; anthers devoid of a terminal appendage, slightly hairy or glabrescent 

 on the back ; follicles cylindrical, incurved, striate : seeds much longer tlum the short naked 

 part of their beak. — SI. t. ISO./. 2. Jacg. Amer. Pict. t. 33.— Urechites, /. MilU. — Pro- 

 portions of the flower as in the preceding, but growth said to be lower and more erect. — 

 Hab. Jamaica! [Jacq.),a,i Kingston; [Cuba!, Haiti]. 



46. E. jamaicensis, 6r. Branchlets climbing, pilose or glabrescent ; leaves cordate- 

 ovate or ovate-oblong, glabrescent, pointleted or pointed, shortly 'petioled ; cymes corymbi- 

 form ; calyx-segments devoid of an interior scale, lanceolate-acuminate from an ovate base, 

 one-third to one-fourth as long as the narrow part cf the corolla-tube ; corolla yellow : cam- 

 panulate part of the tube thrice as long as its cylindrical base, twice as long as the broad 

 lobes ; anthers devoid of a terminal appendage, slightly hairy on the hack above ; follicles 

 cylindrical, acominate, slightly torulose, slender, straightish, suhstriate: seeds much longer 

 than the short naked fart of their beak. — ^E. domingensis, Sw. (non Jacq.) -. compared in 

 Herb. Bks. by Dr. Alexander, but Swartz in his description apparently confounded it with 

 S. neriandra.— Leaves 3"-l", calyx l"'-2"', narrow part of the corolla 4"'-5"', campanu- 

 late part about 1", anthers 3'", follicles 5"-8", seeds (without the beak) 3"' long ; corolla 

 glabrescent, internally hispid below the stamens. — Hab. Bahamas !, Swains, ; Jamaica !, 

 Macf., AL, Lane, Pd., March, Manchester, S. Marys, among shrubs along the coast ; [Cuba I, 

 Haiti I]. 



E. barbata, Desv. (Haiti !, S. Thomas I), is an allied species (calyx-segments pilose, lanceo- 

 late-acuminate, exceeding the narrow part of the coroHa-tube, anthers densely pubescent on 

 the back) : from its variable leaves it might be JE. domingensis, A. DC, but has broader 

 calyx-segments than E. domingensis, Jacq. (Ic. Ear. t. 53) : E. suberecta, Desc. (PI. 7. t. 

 468), said to grow in Jamaica, is perhaps a synonym of E. barbata.

ex. ASCLEPIADE^. 



Character of 4joo(y»e<«, but pollen compound, usually foi-ming wax-like masses (the pol- 

 linaria), which, having a glandular appendage, are connected with the stigma by 5 projec- 

 tions of the latter. — Inflorescence ■usually umbellate ; stamens mostly connected : poUinaria 

 in the West Indian genera 10, the two contiguous ones of adjacent anthers united by a 

 common gland; anthers terminated by a membrane, and inflorescence extra-axillary. 



The properties are the same as in Apocynece . Asclepias affords a diaphoretic medicine 

 (Bastard Ipecacuanha).
