DESCRIPTION OF ALL SPECIMENS EXAMINED: 
Shrub; 2 m. tall, glabrous, the branches erect, 
simple, older branches 3-4 mm. in diameter, 
bark gray, with a few longitudinal fissures; 
leaf scars 3-4 mm. wide, suborbicular, the 
top slightly concave, pale, with 3 bundle 
scars; nodes 2-30 mm., commonly 10-20 
mm. apart; leafy branchlets 2-4 mm. in 
diameter, leafy for 10-19 cm., bearing 8-12 
leaves that ascend, diverging at 45° from the 
stem and not crowded; stipules 2. 5-3. 5 mm. 
long, almost symmetrically deltoid, glabrous, 
the midrib thickened, the margins brown 
membranous; petioles 5-17 mm. long; blades 
6.4-22 cm. long, 18-77 mm. wide, oblance- 
olate, firm chartaceous, above dark green, be- 
low pale green, the apex abruptly contracted 
and short subacuminate and broadly obtuse, 
the margin remotely low serrulate in the outer 
two thirds, the veins raised reticulate and 
prominent, especially below; inflorescences 
1 -flowered, axillary, glabrous; peduncles 1 
mm. long; peduncular bracts 1 mm. long, 
lanceolate; pedicels 2.5 mm. long; sepals 2- 
2.5 mm. long, lance-ovate, glabrous, thin, the 
center dark lined, the membranous margins 
translucent; corolla glabrous, irregular, the 
lower two thirds of the petals forming a con- 
cave channel-like claw, the limb expanded and 
reflexing in anthesis; the lower petal slightly 
larger than the others, 7.8-9 mm. long (when 
boiled), the limb 2. 6-2. 7 mm. long, 1.7-1. 8 
mm. wide, oval, thickened and somewhat 
fleshy, especially in the lower third, reflexed 
and the apex subcucullate; claw 5. 2-6. 3 mm. 
long, 1.4-1. 6 mm. wide, at base membranous 
and 5 -nerved, towards the apex firm and 
deeply channeled; lateral petals 7. 6-8. 8 mm. 
long, oblong-spatulate, the limb 2. 5-3. 2 mm. 
long, 1.4-1. 9 mm. wide, narrowly ovate, 
thickened and firm especially at base; claw 
5. 1- 5. 6 mm. long, 1.5-1 .9 mm. wide, thin 
and with the broad margins membranous, 
strongly 3 -nerved and with 2 more weak 
lateral nerves; upper petals 7.3-8 mm. long, 
oblong, obtuse, the limb 2. 2-2. 3 mm. long, 
1.2- 1. 9 mm. wide, narrowly oval-oblong, 
thickened towards the base; claw 5-5.8 mm. 
long, 1.5-1. 6 mm. wide, narrowly oblong, 
5 -nerved, the central strip thicker, the broad 
margin membranous; stamens subequal, fila- 
ments 0.9-1. 3 mm. long; anthers 0.8-1 mm. 
long, 0.4 mm. wide, obcuneate-oblong, ob- 
tuse, the apex minutely apiculate; sepals 4.5- 
4.7 mm. long, 1.6-2. 4 mm. wide, deltoid 
ovate and obtuse to deltoid-lanceolate, acute, 
the body greenish and 5-7-nerved, the margin 
membranous, ciliate above; corolla glabrous, 
irregular, the lower two thirds of the petal 
forming a concave, channel-like claw, im- 
bricate laterally, enfolding the neighboring 
ones and together imitating a corolla tube, 
the limb expanded and reflexing in anthesis; 
lower petal slightly longer than the rest, 9 
mm. long (when boiled), the limb 2.7 mm. 
long, 1.8 mm. wide, almost oblong, thick- 
ened and somewhat fleshy, the apex sub- 
cucullate; claw 6.3 mm. long, 1.6 mm. wide, 
oblong, membranous, essentially flat, 3- 
nerved; lateral petals 8.8 mm. long, spatulate, 
slightly constricted at apex of claw, the limb
