vidi. 
A glabrous plant, with spreading verruculose branchlets ; leaves oblong-ovate, or ovate- 
lanceolate, or ovate, cordate at the base, with a long acumen, membranaceous, glabrous 
above, with 6-8 pairs of divergent prominulent nerves nearly conjoined close to the 
margins, with reticulated, pellucid, fuscous veins, 23—4 in. long, 1-1} in. broad, on 
petioles 73 lines long ; racemes axillary, longer than the leaves, glabrous, on a peduncle 
33 in. long, bearing laxly many flowers, on glabrous pedicels 7-9 lines long, supported 
by sublinear subglabrous bracteoles 34-44 lines long; sepals narrow, linear-lanceolate, 
subglabrous, of the same length, each with an inner, deeply bifid, subulate scale; corolla 
in bud 12 in. long; tube narrowed below, contracted in the middle; segments dimi- 
diato-obovate, length unknown; stamens inserted in the contraction of the tube on a 
retrorsely pilose ring; disk of 5 truncately ovate lobes, three times shorter than the 
oblong-ovoid acuminate ovaries. 
A species also probably belonging to Laseguea. 
8, AMBLYANTHERA MonrrZiaNa, Müll. in Linn. xxx. p. 421. In Columbia (Moritz 31) : non vidi. 
A scandent species, with hirto-pubescent branches and branchlets; leaves broadly 
ovate, or obovate, cordate at the base, with a short acumen, rigidly membranaceous, 
with 5-6 pairs of divergent prominulent nerves and transverse veins, 22-42 in. long, 
13-23 in. broad, on petioles 7 lines long; racemes axillary, a little longer than the 
leaves, glabrous, on a peduncle 14 in. long, bearing many flowers 1$ in. long on pedicels 
4-6 lines long, supported by linear spathulate bracts 1 in. long; sepals acuminately 
oblong, rugous outside at the base, each with an inner crenately dentate truncate 
scale; tube of corolla narrow as far as the middle, dilated upwards ; segments obovoid, 
less than half the length of the tube; stamens seated in the contraction of the tube; 
anthers short, glabrous; disk of 5 oblong lobes, connate at the base, nearly as long as 
the glabrous eylindrically ovoid ovaries.

575) : non vidi. 
A species differing from the preceding in its smaller, narrow, lanceolate leaves and 
shorter racemes; its slender fuscous branches are pubescently hirtous, 1-13 line thick ; 
leaves linear-lanceolate, obtuse or subcordate at the base, narrowing above into an obtuse 
acumen, subcoriaceous, glabrous above, blackish, shining, reticulately rugous, covered 
beneath with velutinous, woolly, white or yellowish hairs, with 15-18 pairs of horizon- 
tally-spreading nerves, 15-23 in. long, 23-44 lines broad, on petioles 1-13 line long; 
racemes lateral, shorter than the leaves, on a short peduncle bearing many dense 
flowers on pedicels supported by triangularly ovate acuminate bracts ; sepals trian- 
gularly ovate, acuminate, subcarinate, 1 line long, each with an inner, deltoid, denticu- 
late scale; corolla in the whole 1 in. long, yellow; tube narrowly cylindrical for half its 
length, dilating above, pubescent or glabrous; segments obliquely ovate, acute on one 
edge, much shorter than the tube; stamens seated in the contraction of the tube, upon
