Stipules spinescent, up to 5 cm. long, never inflated; other prickles absent.

Morphology Leaves

Leaves with petiole 2-4 mm. long which, like the rhachis, is densely clothed with at first golden then grey spreading hairs; pinnae of well-developed leaves of mature shoots 15-44 pairs (reduced leaves with fewer pairs sometimes also present), mostly 1-2.5 cm. long; leaflets numerous, (1)1.5-2.8 x 0.4-0.7 mm.

Morphology Reproductive morphology Flowers

Flowers white to cream, in heads; heads c. 2-20 per axil, aggregated into a sort of terminal “raceme”, subtended by young to scarcely developed leaves; involucel below the middle of the almost or quite eglandular 1-2 cm. long peduncle, rarely basal.
