Information

Extremities uniformly softly hoary-tomentose. Stipular spines straight or subrecurved, pubescent nearly to the apex. Young leaves, especially on the rachis, silky tomentose; pinnæ in 14–22 pairs; leaflets 20–30 pairs, probably often more numerous, not wholly developed in our specimens; gland sessile near the base of the rachis. Peduncles in pairs or solitary from the lower axils, pubescent, 1–2 in. long. Bracts obsolete. Flowers capitate. Calyx pilose-pubescent, lobes ovate obtuse. Petals externally silky, cohering 1/2 or 2/3 their length, about half as long again as the calyx. Ovary subsessile, glabrous, subtruncate above, with an obliquely inserted filiform style. Fruit unknown.
