202 ON SOUTH-AMERICAN APOCYNACEJE. 
linear-fusiform, compressed, dorsally convex and rugosely striate, flat on the ventral face, 
4 lines long, with a longitudinal raphe and a spreading coma of soft whitish hairs 
8 lines long. 
This species was confounded by Müller with Echites Mansoana A. DC., a very different 
plant with more ovate leaves, from Cuyaba; it is extremely distinct from the Echites 
coalita of Velloz.

A climbing lactescent species, with slender terete glabrous branchlets, with axils 
2-23 in. apart, charged with a few obtuse glands between the petioles ; leaves ovate-oblong, 
rounded or obtuse at the base, acute or acuminate, submembranaceous, reddish green 
and opake above, nerves semi-immersed, scabridulous to the touch, with a broadish, 
dusky, ciliolate gland at the base of the midrib, paler and yellowish opake beneath, with 
immersed fine reddish nerves and reticulated veins, 2-3 in. long, ¿-13 in. broad, on ex- 
tremely slender channelled petioles 3-6 lines long; raceme lateral, on a peduncle 3 lines 
long, trifid at its apex, each branch bearing about 5 approximate flowers on pedicels 
3-4 lines long, minutely bracteolate ; sepals oblong, scarcely acute, imbricate, fleshy, with 
diaphanous margins, 2 lines long, with an inner broad pluridentate scale; tube of 
corolla cylindrical, of a dark purple colour, 10 lines long, swelling a little above the 
middle; segments of a greenish hue, obliquely oblong, 6 lines long, 4 lines broad, rotate; 
stamens inserted on a pilose ring at the contraction of the tube; anthers linear, with an 
acute membrane at the apex, and 2 parallel obtuse lobes at the base; disk of 5 obtuse 
lobes, half the length of the 2 pointed glabrous ovaries; style long and filamentous; 
clavuncle conically oblong, with a membranaceous indusium at its base, terminated by 
2 subulate stigmata. !

A climbing species, differing from Z. trifida, Jacq., in its larger leaves upon longer 
petioles, and its inflorescence: branches terete, sulcate, obsoletely puberulous, lenti- 
cellate, with axils 4-6 in. apart and transversely glanduliferous ; leaves oblong-ovate, 
roundish or subcordate at the base, shortly acuminate, submembranaceous, glabrous, with 
many patently divaricate immersed nerves, midrib sulcate, bearing at its base 2-3 
superposed ovate acute adpressed glands, opake beneath, pallidly ochraceous, fine 
reddish prominulent nerves reticulately veined, 3-5 in. long, 11-2 in. broad, on suddenly 
deflexed petioles 6-12 lines long; raceme lateral, on a peduncle 6 lines long, divided 
at the apex into 2 branches 9 lines long, each bearing numerous approximate flowers, 
on minutely bracteolate pedicels 4-6 lines long; sepals acutely oblong, with membra- 
naceous margins; corolla rose-coloured; tube 12 lines long, swelling above the middle; 
segments broadly dolabriform, 3 lines long; stamens inserted on a pilose ring at the con- 
traction of the tube; follicles free, 8-10 in. long according to Mr. Bentham.
