186 Mr. J. Miers on the genus Marckea. 
Pers. Ench. 1. 218 ;—scandens, glaberrima ; foliis oblongis, 
apice subito acuminatis, imo obtusis, uitidis, subcoriaceis ; 
racemo longe pedunculato, paucifloro, corolla coccinea, calyce 
2—3-plove longiore.—Guiana, v. s. in herb. Hook. (Surinam, 
Hostman, no. 348). 
This is evidently a scandent plant with slender branches; the 
leaves are about 73 inches long, 27 inches broad, upon a some- 
what slender petiole, somewhat thickened at base, } inch in 
length ; they are quite smooth and of thick texture ; the peduncle 
of the raceme 1s axillary, about 3} inches long, bearing a few 
flowers, only one remaining in the specimen above referred tox 
the pedicel 1 is about L inch in length ; the sepals are 14 inch long, 
scarcely 3 lines broad in the middle ; the tube of the corolla is 
13 inch long, 2 lines in diameter, swelling to half an inch below 
the mouth; the lobes are 5 lines long, 4 lines broad, rounded, 
veined, overlapping each other on their margins, and when ex- 
panded, form a border about 14 inch in diameter ; the insertion of 
the stamens is about half an inch above the base of the tube, the 
filaments are very slender, nearly an inch long, and the anthers 
are 3 lines in length ; the berry is 8 lines long, 4 lines in diameter, 
apparently quite free of pulp, with a thin pericarp and slender 
dissepiment, containing numerous divaricate, ascending, imbri- 
cate seeds, each about 13 line in length*. 
2. Marckea? longiflora (n. sp.) ;—scandens, ramulis glabris com- 
pressis ; folus alternis, oblongis, apice repente acuminulatis, e 
medio ad basin subattenuatis, breviter petiolatis, coriaceis, 
glaberrimis, opacis; racemo sub-brevi, paucifloro ; corolla calyce 
4—5-plo longiore, tubo supra medium cylindraceo-campanulato, 
limbi laciniis ovatis, subreflexis, staminibus inclusis.—Trini- 
dad, v. s. in herb. Hook. (la Laguna de Ora pouche, Purdie.) 
This plant corresponds in its habit with Marckea, but the spe- 
cimen above referred to presents only a single flower in a very 
bad condition, so that it 1s impossible to determine with certainty 
whether or not it belongs to this genus. The leaves are 7} inches 
long, 33 inches broad, on a somewhat slender petiole thickened at 
base, and half an inch in length ; they are quite coriaceous, opake 
but not polished, though entirely glabrous ; they are marked with 
strong prominent nerves; the peduncle of the raceme is appa- 
rently about 12 inch long, the pedicel 8 lines; the calyx exactly 
corresponds with that of the preceding species, the sepals being 
nearly an inch long, including their suddenly contracted linear 
apical points of 3 lines ; they are about 4 lines broad, with nearly
