A species very near 4. Lindeniana; a subscandent plant, with more remote axils; 
leaves roundish, scarcely cordate, acute, dark green above, with paler margins, pallid 
brown beneath, with immersed nerves 12-12 in. long, 7-8 lines broad, on petioles 1 line 
long; inflorescence not stated; sepals acute, with 2 small acute inner scales; tube of 
corolla 7 lines long, narrow below the middle, widening upwards ; segments dolabriform, 
dextrorsely convolute, 6 lines long, 5 lines broad, unequally expanded ; stamens inserted 
in the contraction of the tube; anthers glabrous, acute, shortly 2-lobed at the base, on 
shortish pilose filaments; disk tubular, subconical, submembranaceous, 5-sulcate.

A species with tortuous, scabridly pubescent branches; leaves elliptic, subcordate, 
acuminate, coriaceous, very glabrous, shining above, velutinous beneath, 3 in. long, 14- 
16 lines broad, on petioles 2 lines long; peduncle shorter than the leaves, bearing many 
densely congested flowers, on pedicels a little shorter than the calyx; sepals acutely 
ovate, puberulous outside, each with an inner obtuse scale; corolla hypocrateriform, gla- 
brous; tube narrowly cylindrical, contracted in the mouth, 10-11 lines long, with a 
ring of retrorse hairs above the middle ; segments half as long as the tube; stamens in- 
serted in the pilose ring; anthers acute; disk urceolate, nearly entire or undulate on 
the margin; follicles 2, erect, torulose, glabrous, 3-4 in. long; seeds with a rufescent 
coma.

cordate, shortly acuminate, pubescent, membranaceous, undulate, hoary beneath, 2-4 in. 
long, 14-2 in. broad, on petioles 6-9 lines long; racemes shorter than the leaves, simple, 
pubescent, bearing many flowers on pedicels 3 lines long; sepals obtusely ovate; corolla 
14 in. long, glabrous ; tube narrowly cylindrical, a little swollen above; segments half 
its length ; stamens inserted on a pilose ring at the contraction of the tube; anthers ob- 
tusely bilobed at the base; disk cylindrical, 5-striate, shorter than the ovaries. 
PERICTENIA *. 
This genus is proposed for a handsome Peruvian plant of Spruce's collection, distri- 
buted under the name of Echites stipellaris. This approaches Dipladenia in habit ; its 
axils are furnished with a pectiniform ring of long stipules, as in Mandevilla; the seg- 
ments of the corolla are elongated horizontally, and introplicate in sestivation, so that 
their tips descend into and far below the mouth of the tube, as in Bonafousia. 
* From repl (circum), «reis ( pecten), from the pectiniform ring of stipules at the nodes.
