A plant with slender glabrous branches, much resembling 4. geminata: leaves 
elliptic, obtuse at the base, roundish at the summit, with a short cuspidate acumen, sub- 
coriaceous, glabrous, shining and fuscous green above, rufescently opake beneath, nerves 
and veins prominulent on both sides, 34-44 in. long, 12-23 in. broad, petiolate ; panicle 
axillary, spreading, much longer than the leaves, bearing numerous flowers on slender 
pedicels 3 or 4 times as long as the calyx; sepals obtusely ovate; tube of corolla cylin- 
drical, narrowed below, contracted in the middle, a little wider above; segments nearly 
half the length of the tube; anthers dorsally glabrous; disk as in the preceding 
species.

A species with subhirsute branches, having remote axils; leaves obovately oblong, 
narrowing towards the base and there auriculately cordate, cuspidate-acuminate, sub- 
membranaceous, with revolute margins, light green and opake above, scabridulous or 
adpressed pilosulous, with immersed nerves, beneath flavescent and opake, hirtulous, with 
prominulent slender nerves, 2-5 in. long, 14-3 in. broad, on petioles 8-15 lines long; 
raceme lateral, 4 in. long, sparsely hirsute, bearing many flowers, on pedicels 3 lines 
long; sepals lanceolate, membranaceous, 24 lines long, with an inner deltoid bidenticu- 
late scale; corolla 24 in. long, glabrous, reddish-coloured ; tube cylindrical as far as the 
middle, then funnel-shaped ; segments inequilaterally oblong, subacute, dextrorsely conyo- 
lute, marked near the base and within the tube with many interrupted yellow lines ;
