 (non 430). In Peruvia et Bolivia : v. s. in herb. Mus. Brit. Lacarejo^ Sorate (Mandon 1473). 



A climbing species, with slender glabrescent branchlets, with axils 3-4 in. apart, 

 charged on each side with 3-4 rounded glands ; leaves ovate, cordate at the base, with 

 rounded lobes somewhat folded, terminated by a long, suddenly cuspidate acumen, 

 membranaceous, subglabrous above, with subscandent semi-immersed nerves, bearing at 

 the base of the midrib 3-5 subulate glands, cinereo-puberulous beneath, S^-SJ in. long, 

 2-2f in. broad, on pubescent petioles 5-9 liaes long ; panicle simply racemose, lateral at 

 the axils, 8 in. long, on a glabrous peduncle bare at the base for 3J in., bearing several 

 alternate or secund flowers on pedicels 9 lines long, supported by lanceolate bracteoles ; 

 sepals lanceolate, gibbous at the base, submembranaceous, pilose outside, 6-7 lines long, 

 1 line broad, each with a broad deeply and acutely lacinulated scale ; corolla glabrous, 

 tube 1 in. long, narrower below for one fourth of its length, subventricose in the middle ; 

 segments oblong, obliquely inequilateral, 5 lines long, glabrous, with dextrorse convo- 

 lution ; stamens seated in a pilose ring in the contraction of the tube ; filaments short, 

 retrorsely pilose ; anthers subcoherent, 5 lines long, membranaceous above, with 2 short 

 obtuse basal lobes ; disk of 5 oblong lobes, emarginated at the summit, shorter than the 2 

 oblong pointed ovaries ; follicles 2, terete, straight, subparallel, 7 in. long, 1^ line thick ; 

 placenta ^ line broad ; seeds many, oblong, compressed, pruinose, with a longitudinal 

 raphe, 4 lines long, f line broad, surmounted by a softly sericeous spreading coma 9 lines 

 long.

The Amblyanthera convolvulaced of Miiller belongs to his variety pubescem from 

 Mexico. 



7. EcHiTEs PALLIDA, nob. : Echites sp., Benth. in Plant. Hartweg. p. 120. In Ecuador : v. s. in herb. 

 Mus. Brit. Guayaquil (Hartweg 670) . 



A species with terete branches, the axils 3 in. apart, furnished on each face with 2 

 acute stipules ; leaves ovate, roundishly truncate and broadly subcordate at the base, 

 gradually acute above the middle, glabrous, very membranaceoas, above pale green, 

 opake, 5 converging nerves near the base, with others lateral and ascendingly divergent 

 and prominulent, beneath equally paUid, midrib prominent, nerves and transverse veins 

 little prominent, 3^ in. long, 2| in. broad, on rather slender, yellowish, channelled 

 petioles 10 lines long ; racemes terminal, binate, shorter than the leaves, on suddenly 

 reflected peduncles bare at the base for 9 lines, thence bearing several crowded spicate 

 flowers, with imbricate, membranaceous, lanceolate bracts, each 6 lines long ; pedicels 

 4 lines long ; sepals lanceolate, very membranaceous, pale, 6 lines long, 1 line broad, 

 each with a roundish ciliate inner scale, all quite glabrous. The corolla had fallen 

 off', leaving in its place 2 very immature follicles supported by the sepals and disk 

 cleft nearly to the base into 5 oblong submembranaceous lobes ; these immature 

 follicles are flattened, linear, straight, pale yellow, pruinosely pilose, IJ in. long, 1 line 



broad.
