glabrous above, ciholate with forwardly ascending sthf hairs up to 0.25-0.5 mm,
beneath charged with scattered minute thickened trichomes, the inflorescence
composed of subsessUe or shortly pedunculate few-fld racemes axillary proxi­
maUy to fuUy developed lvs, these distally ± abmptly reduced to a mdimentary
If-stalk with undiminished petiolar gland, the uppermost racemes forming a short­
ly exserted narrow thyrse.
Stipules loosely erect, thinly herbaceous often hvid-tinged or purple-dotted,
broadly triangular- to lance-acuminate (3-)4.5-ll(-13) x (1.5-)2-4.5(-5) cm, at
obhque base, either on side further from petiole or (when broad) on both sides,
rounded and bluntly auriculate-amplexicaul, early dry caducous.
Major lvs (except in rare starveling plants) 11-24(-26) cm; petiole with swoUen
or little dhferentiated, sometimes discolored pulvinus 2.5-5(-5.5) cm, at middle
0.8-2 mm diam, bluntly 3-costate dorso-laterahy, thickly obtusely margined and
openly grooved ventrally; gland contiguous to pulvinus sessile or almost so,
plumply ovoid, hemispherical, depressed-hemispherical or subglobose, in profile
0.7-1.8 X (0.6-)0.8-2.2 mm, varying from a little longer to a httle shorter than
diam, always obtuse, when fresh hvid-reddish, nigrescent and wrinkled when
dry, sometimes a second gland near the first, but none between hts; rachis
(4-)6-14 cm, its subulate or hornhke terminal appendage thickened and Uvid
proximaUy; pulvinules discolored (1.7-)2-4 mm; lfts (3-)4-6, of most plants ex­
actly 4 or 5 pairs, accrescent distally, the proportionately broad proximal pair
much the shortest, the distal pair broadly lance- or ovate- (exceptionally obovate)acuminate
4.5-9.5(-10) x (1.2-)1.4-3.5(-3.8) cm, (2.1-)2.4^(-5) times longer
than wide, at inequilateral base cordately decurrent on pulvinule on proximal or
on both sides, the midrib immersed or scarcely raised above, carinhorm beneath,
the 9-15 pairs of major camptodrome and random intercalary secondary veins
finely prominulous above, more sharply so beneath, the tertiary venulation invisible
on both faces or discolored but scarcely raised beneath.
Peduncles (l-)1.5-4.5(-7) mm; racemes very shortly or subumbellately (l-)2-5-
fld, the axis becoming 0-5 mm, the whole axis including peduncle not over 1 cm;
bracts thinly herbaceous early dry brown caducous, lance (oblance)-acuminate
(5_)6-16(-18) X (0.8-)1.8^.5 mm; mature pedicels 8-17(-21) mm; fl-buds nodding
glabrous (pubemlent at base), plumply obovoid; sepals submembranous pal­
hd or commonly pinkish- or fuscous-tinged, moderately graduated, obovate or
oblong-obovate, the outer (5-)5.5-7.5 mm, the longest inner one (6.5-)7-10 mm;
petals glabrous, yehow drying whitish brown-veined, the vexihar one usuaUy
obcordate, the 2 lateral ones obovate, the 2 abaxial ones oblanceolate, ah of equal
length or either the anterior or posterior ones longer, the longest petal 12-16(-17)
mm; androecium glabrous, the 3 staminodes 0.7-1.2 mm wide, the filaments of
4 median stamens 2-3.3 mm, of 2 large abaxial ones dilated and 5-7 mm, ofthe
SterUe centric abaxial one 3-4 mm, the anthers of 4 median stamens including the
2-lipped ascending beak 3.2-5.2 mm, those of 2 large abaxial ones, measured
from base to constriction beneath the beak, 3.7-5 x 1.1-1.5 mm, the beak 1.2-1.6
mm, its thickened tonguelike abaxial lobe (0.6-)0.8-1.2 mm, the anther ofthe
centric stamen up to 2 x 0.6 mm, but often filiform or 0; ovary densely whitestrigulose
or -pUosulous; style glabrous, keeled lateraUy and ventraUy, (3-)3.2-4.7
mm, a Uttie dUated distaUy and 0.35-0.5 mm diam toward apex, the introrsely
lateral stigmatic cavity eUiptic-oblanceolate in ventral view, its margins explanate
and barbellate along the sides, minutely porrect at tip; ovules 40-60 (average 51).
Pod normally erect or ascending at narrow angles, sessile or almost so, Unear,
