its much more slender habit, its branches very weak, twining, or simply sub- 
dichotomous, furnished at its rather remote nodes with a pectinate ring of fleshy 
slender stipules; the inflorescence is lateral and pendulous, upon an elongated bare 
peduncle, bearing above a few large campanulate laxly secund flowers, upon pedicels 
without bracts, thus differing from the peculiar characteristics of Amblyanthera.

A twining plant, with large odoriferous flowers, sent home by Tweedie in 1840, from 
Buenos Ayres, where he found it cultivated under the name of Jasmin de Chile. It has 
subglabrous branches about the thickness of a erow's quill, with axils 34 in. apart, fur- 
nished on each side with 6 acute fleshy stipules 2 lines long, united in a pectinate ring; 
leaves oblong, cordate at the base, acute, submembranaceous, glabrous above, paler beneath 
and glaucous, with hairy tufts in the axils of the brown nerves, the veins very reticulate, 
23 in. long, 12 in. broad, the basal sinus 2-3 lines deep, on petioles 1-2 lines long; 
raceme lateral, pendent, on a glabrous peduncle bare at its base for 2 in., bearing above 
several alternate flowers on ebracteate secund pedicels about 4-4 in. apart, 9 lines long; 
flowers cream-coloured, odoriferous, 24 in. long; sepals lanceolate, erect, subimbricate, 
4 lines long, each with a broad pectinate scale within, as long as the disk; tube of 
corolla 1j in. long, narrowed cylindrically at the base for half its length; segments 
dextrorsely convolute, broadly dolabriform, the sinister angle acute, sinuate above, 
rounded, 1 in. long, 9 lines broad; stamens seated in the contraction of the tube, on a 
densely pilose ring; filaments retrorsely hispid ; anthers oblong, cohering, with a mem- 
branaceous apex, obtusely bilobed at the base; style slender; clavuncle incrassate, 
oblong, 5-grooved, with a basal peltate membrane ; stigmata 2, small, erect; disk of 5 
fleshy, oblong, truncate lobes, shorter than the 2 pointed oblong ovaries; follicles 2, 
terete, parallel, pendent, 1-14 foot long; seeds with an apical coma. 
AMBLYANTHERA. 
This genus, proposed by Miller in 1860, has not been acknowledged by other botanists. 
The name was given on account of the short, obtuse, basal lobes of its anthers—a cha-
