Common name: None
Sprawling shrub 0.25-0.6 X 0.4-2 m; main branchlets raised-tomentose, with moderately dense coarse white T-shaped hairs, the awns soon breaking away leaving tuberculate bases, with short axillary shoots on almost every node; leaves ascending or downturned by the presence of axillary shoots, rigid, linear to subulate, rarely narrow-ovate, 0.2-0.8 cm X 0.7-2.5 mm, upper surface initially raised-tomentose, quickly to tardily glabrescent leaving tubercles 0.05-0.1 mm high, with the midrib sometimes prominent, lower surface appressed-tomentose but usually obscured by recurved margins, apex acute, grading into a mucro 0.2-0.45 mm rarely to 0.6 mm long.
Racemes subterminal on short shoots, umbellate, with 1-4 flowers; rhachis 0.5-10 mm long; pedicel, torus and limb moderately densely raised-white-pubescent, the perianth tube externally glabrous or with a few very short hairs; pedicel 4-7 mm long; torus very oblique; perianth 8-11 mm long, the stout red tube recurved below the white limb which reaches halfway down, splitting down one side only, internally densely hirsute around the summit of the ovary, glabrous below, glabrous or with very few hairs above; gland prominent, thick, semicircular, horizontal; very short gynophore and ovary white-hirsute; style 19-23 mm long, curved, exserted well above the perianth, red, with short raised white hairs at the base only or extending almost to the apex; pollen-presenter an oblique concave disc with a short broad central cone.
Fruit curved, narrow-ovoid, c. 12 mm long, covered by short appressed hairs mixed with some long raised hairs, vertically inserted on the c. 8 mm long stipe, with a terminal erect style; young seed narrow-oblong, with a groove on one side lined by a very narrow wing extending into the longer caruncle-like apical protuberance.
