Passerina galpinii C.H.Wright

Stunted or erect, much-branched shrubs, (0.1-)0.3-1.0(-1.2) m high. Stems light greyish brown: indumentum of young stems greyish brown tomentose; cork grey-brown, fissured lengthwise, with sclerenchyma fibres protruding between fissures; leaf scars rounded. Leaves greyish green, imbricate, overlapping 10%-25%, diverging at an angle of 30°, plane shape linear, incurved towards apex, length x depth 2.9-4.5 x 0.5-0.8 mm, adaxial surface concave, comose, abaxial surface convex, chartaceous, glabrous; base sessile; apex subacute to obtuse; margins glabrous, involute. Inflorescences with spikes subterminal, usually congested, 8-10-flowered, axis whitish tomentose, proliferating growth common. Bracts appressed, oblate, length x depth (3.6-)4.5 x 1.1(-2.2) mm; lamina greyish green, adaxially concave (inside), abaxially convex (outside), chartaceous, glabrous outside, midrib extended into leaf-like point, tomentose inside; wings straw-coloured, membranous, broadly rounded, bullate; base cuneate; apex subacute; margins glabrous, involute. Floral envelope ±5.3 mm long, papyraceous and yellow-pink during pollination, dehydrated after shedding of pollen, turning red to brown. Hypanthium pubescent at ovary, neck pubescent, ±1 mm long. Sepals: outer sepals concave elliptic, glabrous, inner sepals obovate, abaxially glabrous, apex margin adaxially tomentose. Androecium with filaments of antipetalous whorl ±1.4 mm and those of antisepalous whorl ±2.1 mm long: anthers ±0.6 x 0.5 mm, sub-basifixed. 2-thecous and 4-locular. Ovary ±2.0 x 1.1 mm. Fruit an achene with pericarp membranous and dry, ±2.5 x 1.2 mm, enveloped by persistent, loosely arranged hypanthium, breaking up at circumference of ovary, resulting in the sepals and androecium being shed.
