A climbing species, resembling E. laxa, with pubescent branchlets, afterwards glabres- 

 cent ; leaves ovate-oblong, cordate, acuminate, glabrous above, with many glands at the 

 base, glabrous beneath, but villous in the axils of the nerves, 3^4 in. long, 1-1^ in. 

 broad, on petioles 1 in. long ; raceme lateral, bearing 5-8 flowers on pedicels supported 

 by acutely ovate bracteoles ; sepals acutely ovate ; corolla 2\ in. long ; tube yellow, con- 

 stricted below the middle, somewhat funnel-shaped ; segments dark purple, obliquely 

 obovate, obtuse ; stamens inserted on a pilose ring at the constriction of the tube ; fila- 

 ments pilose ; anthers glabrous.

A plant referable to this group on account of its bidentate glandular stipules and the 

 presence of bicuspidate glands at the base of the leaves; its branches are fuscous, 

 glabrous, and smooth ; its branchlets subpuberulous, with bidentate stipules around the 

 nodes ; the leaves are elliptic-oblong or lanceolate, shortly acute, rounded at the base, 

 glabrous above, with bicuspidate glands at the base of the midrib, paler beneath, with 

 about 8 pairs of subobsolete nerves ; raceme lateral ; peduncle bifid, with smooth branch- 

 lets and smooth, ovate, rounded, subcUiolate bracteoles ; sepals ovate, subcUiate ; tube 

 of corolla cylindrical, staminigerous above the middle, a little bell-shaped in the mouth, 

 with a border of 5 shortish segments.

(non R. & P.) I. c. p. 413 : Amblyanthera microcalyx, var. trichantha, MiiU. Linn. xxx. 448. In Vene- 

 zuela prope Caracas : non vidi. 



A climbing plant, 8 feet high, with very slender puberulous branches ; leaves oblong- 

 ovate, cordate, acutely acuminate, membranaceous, subglabrous above, the midrib charged 

 with many dark fleshy glands, pilose beneath, 1^-2^ in. long, 7-10 lines broad, on slender 

 petioles 2 lines long ; peduncle of the raceme pubescent, shorter than the leaves, bearing 

 above 4-6 approximate flowers, on pedicels 3 times as long as the calyx ; sepals linear- 

 lanceolate, ciLiate on the margins, scarcely 2 lines long, gibbous at the base, with an acutely 

 ovate inner scale ; corolla 1^ in. long, pubescent, with white patent hairs ; tube cylindrical, 

 9-10 lines long, broader above the middle ; segments half as long as the tube ; stamens 

 seated near the contraction of the tube, on a pilose ring of white retrorse hairs ; anthers 

 2^ lines long, shortly 2-lobed or emarginate at the base, acuminate above, cohering. 



The lEohites suhsagittata, Griseb. (non R. & P.), from Trinidad, belongs here. The 

 floras of the latter island and the opposite coast of Venezuela are largely identical. 



30. Echites brachtloba, nob. : Amblyanthera brachyloba, Miill. Linn. /. c. p, 423. In Peruvia, Parana- 

 hunanco (Matbews 820) : non vidi. 



A plant evidently belonging to this genus, on account of the glands on its leaves. It 

 lias very slender puberulous branchlets ; leaves ovate, cordate at the base, obtuse at the 

 summit, membranaceous, sparsely and minutely puberulous above, the midrib charged
