DESCRIPTION OF TYPE: "A slender, wand- 
like shrub, two to six feet high, simple or 
sometimes sparingly branched, the branches 
ascending,” plant glabrous; older bark brown 
to gray, smooth or longitudinally wrinkled, 
the stems 3-5 mm. in diameter, roughened by 
the persistent rigid stipules; leaf scars 2 mm. 
wide, depressed rounded shield-shaped, pale, 
with 3 bundle scars; leafy branchlets 2-3 mm. 
in diameter, leafy for 10-25 cm., the inter- 
nodes 4-23 mm. long, hence the stipules re- 
mote; leaves alternate, spreading, numerous 
but not crowded; stipules 3.2-4 mm. long, 
obliquely narrow deltoid, with a broad 
thickened midrib, the membranous margin 
ciliolate; petioles 2-3 mm. long, stout; 
blades 3-10.5 cm. long, 12-44 mm. wide, 
oblong-oblanceolate to elliptic-oblanceolate, 
subcoriaceous, prominently netted reticu- 
late veined above and below, above dark 
green, below tawny green, the margins shal- 
lowly undulate or obscurely serrulate; flowers 
axillary, single or several, the peduncle 2-3 
mm. long, covered by stiff bracts similar to 
but smaller than the stipules; sepals 2.8-3. 1 
mm. long, 0.9 mm. broad, lanceolate, the 
back glabrous, prominently 3-nerved and 
dark in the center third, the rest pale and 
membranous, the margins puberulous cilio- 
late in the upper third; corolla irregular, gla- 
brous, the lower two thirds of the petals 
forming a concave channel-like claw, imbri- 
cate laterally, enfolding the neighboring ones 
(but not spirally so, as shown in Heller’s 
plate LIV) and imitating a corolla tube, the 
limb expanding and reflexing in anthesis; the 
lower petal longer and larger than the others, 
13 mm. long (when boiled), the limb 4.7 mm. 
long, 2.8 mm. wide, elliptic oblong, thick 
and fleshy, almost flat, the apex retuse; claw 
8.5 mm. long, 2.5 mm. wide, at base mem- 
branous and 5 -nerved, towards the apex 
firmer and channeled; lateral petals 12 mm. 
long, narrowly spatulate, slightly contracted 
at apex of claw, membranous, especially be- 
low; limb 3.3 mm. long, 2 mm. wide, oval; 
claw 8.5 mm. long, 1.8 mm. wide, 3-nerved 
from the base; upper petals 11 mm. long, 
narrowly spatulate, membranous; the limb 
3.2 mm.‘ long, 2 mm. wide, oval; claw 7.8 
mm. long, 3 mm. wide, membranous, 3- 
nerved; stamens subequal, filaments 1.7 mm. 
long, tapering upwards from the 0.4 mm. 
wide base; anthers 1.1 mm. long, 0.6 mm. 
wide, elliptic oblong, bearing at the apex an 
incurved bristle 0.1 mm. long; capsules 9-10 
mm. long, ovate-lanceoloid in outline, deep- 
ly 3-lobed, beaked by the persistent style, 
greenish to brown, reticulate veined, the 
lobes 2-seeded, dehiscing to the base; seeds 
2. 1-2. 3 mm. long, 1.7 mm. wide, shining, 
stramineous, the apex truncate, depressed.
