8 mm, slightly pubescent, curved, connective not elongated, glabrous
, staminode ca.
Elytron 2.4x longer than wide, with shallow punctures along the striae, and the interstriae weakly rugo-punctate, mostly glabrous
, with a few scattered short setae near posterior borders.
Inflorescences borne in pairs on older stems axillary to scars of shed leaves, never in axils of current leaves; pseudoracemes 10-16 cm long with the slender axis sericeous, without vegetative leaves below the flowers, the flowers 16-34 or more, borne proximally in pairs but distally in no consistent arrangement; proximal bracts 3-4 mm long, distal bracts 1.5-2 mm long, triangular, abaxially sericeous, adaxially glabrous
, all eglandular; proximal peduncles 2-4 mm long, distal peduncles 1-1.5 mm long, sericeous; bracteoles ca.
, with 1-3 setae at corners on either side of head.
Leaves clustered near the median part of the stem; sessile to long-petiolate; blades ovate, obovate, three-lobed, palmately, pinnately, or three-veined to subpalmately veined, margin dentate to serrate, glabrous
to slightly pilose especially beneath.
Petals white, obovate or broadly ovate and glabrous
. Stamens 20, shorter than petals.
These are glabrous
and dichotomously branched with their first leaves depressed obovate, and with open dichotomous venation (Fig.

In the dermis, there are Ruffini endings and Pacinian corpuscles in a glabrous
(or hairless) skin, whereas there is a complex combination of mechanoreceptors and their associated nerves and hair follicle receptors in a hairy skin [23, 24].
