drical and constricted below the middle, funnel-shaped above; segments trapezoid ; 
stamens inserted in the constriction of the tube, with connivent anthers; disk vasiform, 
finely denticulate on the margin, striolate, fleshy, and concealing the 2 subulate ovaries.

A species from the same region as the preceding, to which it is nearly allied.  Müller's 
drawing is copied from that of Martius above cited ; and it is stated to be near 4. 4mazo- 
nica in its leaves and inflorescence. Its stoutish branches are trichotomously or oppositely 
divided, fuscous, verruculous, with axils 2-23 in. apart; leaves elliptic, subacute at both 
ends, or with a suddenly contracted, short, obtuse acumen, subcoriaceous, fuscous above, 
glabrous, subnitid, with about 10 pairs of diverging nerves and finely reticulated veins, 
paler beneath, 33-43 in. long, 14—2 in. broad, on petioles 3-7 lines long; panicles opposite, 
axillary, longer than the leaves, on a bare peduncle 2 in. long, erect, above trichotomously 
branched, each branch bearing about 6 flowers on bracteolate pedicels 5-6 lines long; 
sepals small, ovate, acute, pubescent, thickish, imbricate, 2 lines long, each with a small 
inner, bidentate scale; tube of corolla subglabrous, 14 lines long, narrowly cylindrical at its 
base for one third of its length, widening a little above; segments trapezoidally dolabri- 
form, with crispate margins, 9 lines long, 6 lines broad ; stamens seated in the contraction 
of the tube; anthers acuminate, with 2 shortish, acute, subdivergent, basal prongs, hirtu- 
lous dorsally ; disk urceolate, enclosing the 2 somewhat shorter, acutely ovate, glabrous 
ovaries.

A species differing from the preceding in the unusual size of its leaves, which are more 
oblong, 74-10 in. long, 34-4 in. broad; the inflorescence is 5 in. long; other particulars 
are not given. It seems to differ little from the 4nisolobus Perottetii, Müll. (non A. DC.).

A species scarcely differing from 4. Cururu. Its branches are more slender, brownish, 
striolate, glabrous, subverrucose, with axils 1} in. apart, having a short stipule on paca 
side of the petioles ; leaves elliptic, narrower towards the base, roundish at the summit, 
and suddenly constricted into an acute acumen, opakely fuscous above, with 10 or 
12 pairs of divergent nerves, and transverse veins finely reticulate, yellowish opake 
beneath, with reddish prominent midrib and nerves, 43-53 in. long, 14-24 in. broad, on 
petioles 4-5 lines long; panicles opposite or subterminal, pubescent, on a naked p Bp 
14 in. long, bearing several branches 4-6 lines long, supporting scveral subapproximate 
flowers on pubescent pedicels 6 lines long, with minute ovate bracteoles ; sepals veer? 
oblong, with submembranaceous margins, 1} line long, } line broad; tube of corolla 15
