Arborescent shrubs and round-headed trees 2-4 m with trunk attaining 25 cm
diam, except for the glabrous upper face of lfts pUosulous throughout with straight
spreading, spreading-incurved or less often incumbent yeUowish hairs up to
0.3-0.6 mm, the hts in addition charged beneath with many short thickened or­
ange trichomes, the ample foliage bicolored, the hts when dry dull dark brownish-
green above, paler beneath, the inflorescence a panicle of racemes proximally
leafy-bracteate and immersed in fohage but often shortly exserted distaUy.
Stipules spreading-incurved or reflexed, firmly herbaceous, when spread out
broadly oblanceolate acute or acuminate (4-)5-8.5 x (2-)2.5-5 mm, but the blade
folded backward on itseh and thus appearing falcately oblanceolate, deciduous
tardily but before the h.
Lvs (except some high in the panicle) 8-18 cm; petiole including turgid but not
much dUated pulvinus 10-26(-37) mm, at middle 0.9-1.8 mm diam, narrowly
winged and openly shallowly sulcate ventrally; rachis (2.5-)3.5-9.5 cm, the longer
interfoholar segments (10-) 12-21 mm; glands (much eaten) sessile or shortly stipi­
tate between proximal and often some or all distal pairs of lfts, in profile 1.2-2.5
mm tall, the ovoid or lance-ovoid acute body 0.5-1.1 mm diam; pulvinules
l-I.8(-2) mm; hts 4-6(-7) pairs, strongly accrescent distally, the terminal pair
broadly lance- or narrowly ovate-elliptic, obtuse mucronulate or triangular-acute
3-7(-7.5) X 1-1.9 cm, 2.6-3.7 times as long as wide, at strongly asymmetric base
cordate always on proximal and sometimes on both sides, the margin strongly
revolute, the midrib deeply and 8-13 pairs of camptodrome secondary veins faintly
depressed-sulcate above, all sharply elevated beneath, a few weak intercalary
secondary veins visible beneath but ah tertiary venulation immersed.
Racemes mostly 10-35 (some depauperate distal ones only 4-10)-fld, the 1-3
simultaneously expanded fls raised about to level of spreading-ascending fl-buds,
the axis together with stout ascending peduncle becoming (4-)6-16 cm; bracts
submembranous ovate- or triangular-acuminate 4-8(-9) x 1.5^(-5) mm, early
papery and usuaUy deciduous before full anthesis; mature pedicels 1.3-2.8 cm;
fl-buds obUquely obovoid, thinly pUosulous externaUy at least at base, the inner
subpetaloid sepals glabrate; sepals not strongly graduated, obovate or the inner
oblong-obovate, the smahest outer one (5.5-)6-9 mm, the largest inner one
(7-)8-10.5 mm; petals glabrous, zygomorphic, the vexiUar one broadest emarginate,
the abaxial ones narrowest, the longest 11.5-16 mm; staminodes x 1-1.4
mm; filaments of 4 median stamens 1.7-2.8 mm, ofthe centric abaxial one 2.7-4
mm, ofthe 2 long latero-abaxial ones dilated 4-6.5 mm, the anthers of 4 median
stamens 4.4-6 x 1.2-1.4 mm, obhquely truncate at apex, of the centric sterile
abaxial one 5-6 x 0.5-0.7 mm, ofthe 2 long abaxial ones 6.6-8.5 x 1.5-1.9 mm,
Innately lanceolate in outhne, bluntly sagittate at base, subhorizontaUy truncate
at apex and 2-porose; ovary densely strigulose-pUosulous; style glabrous Unear-
