Weak shrubs and treelets at anthesis 1^ m, in habh, stature, fohage and form
of inflorescence essenrially similar to remotely aUopatric C. fruticosa but differing
in minor detaUs of the androecium and definitively in the pod and seeds, the
young branchlets either sharply or obscurely 4-angular and hke the foliage and
axes of inflorescence variably strigulose-pUosulous with forwardly incumbent,
less often straight subappressed or flexuously erect hairs up to O.15-0.3(-0.5)
mm, the fohage bicolored, the membranous lfts above duU or sublustrously oli­
vaceous and minutely puberulent or rarely glabrous, beneath paler and always
densely pubescent, the sohtary racemes commonly all subtended by ample lvs
but some, at least in late anthesis, often forming a shortly exserted leafless pan­
icle, the primary axis in age flexuous or abruptly zigzag.
Stipules caducous (httle known), hnear-setiform or very narrowly hnear-oblan-
ceolate straight or incurved ±5-8 x 0.25-0.6 mm, absent from many flowering
and all fruiting spms.
Lvs (disregarding obviously reduced distal ones) 11-34 cm; petiole including
pulvinus (2.5-)3-8.5 cm, at middle 1.2-2.8 mm diam, prominently 5-ribbed, the
shallow open ventral groove dUated toward the petiolar gland; rachis 1.5-5 cm,
a httle shorter than petiole; gland 1 sessUe or less often shortly stipitate between
proximal pair of lfts, including stipe 1.5-3.5 mm tall, the body varying from
plumply ovoid or ovoid-pyramidal to narrowly fusiform (0.6-)0.8-2.5 mm diam
glabrous; pulvinules (2-)2.5^.5(-5) mm; distal pair of lfts obhquely ovate- or
obovate-elliptic, usually shortly acuminate but either obtusely or acutely so,
(8-) 10-21 X 4-9 cm, (L6-) 1.8-2.5 times as long as wide, the base, venation and
reticulation as in C fruticosa, but the reticulation of dorsal face quite variable,
the ultimate areoles sharply defined on dorsal face ±0.2-1 mm diam.
Racemes (4-)8-25-fld, the axis including peduncle becoming 1.5-10 cm; bracts
early dry deciduous at or before anthesis ovate, narrowly triangular or lanceolate
(l-)1.5-3.5 mm; pedicels at and after fuU anthesis (13-)16-30(-35) mm; young
buds globose, glabrous above very base or thinly pilosulous overaU; sepals variable
in ouriine and in relative size, the outer sometimes almost as long as inner,
somerimes only half as long, aU oblong or obovate, concave, always obtuse, the
longest inner one 5.5-10.5 mm, at first submembranous and fainriy or obsoletely
venulose, yellowish-green or red-ringed, becoming dry and rather prominently
3-6 nerved; petals of ser. Bacillares, the longest one 12-20 mm; funcrional sta­
mens 7, the filaments glabrous or puberulent, all filiform (not thickened distaUy),
those of 4 median ones 1.4-2.6 mm, those of 3 abaxial ones 2.5-4(-5.5) mm;
anthers glabrous or almost so, those of 4 median stamens slighriy incurved
(4.3-)4.6-7.5(-8) mm, with divaricate 2-porose beak 0.3-0.55 mm, those of 3
abaxial ones (4-)5.5-10.5(-12) mm, with more strongly incurved body contracted
into a porrect, also 2-porose beak 0.8-1.6 mm; ovary densely strigulose; style
