Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

.Montane to alpine (> 300 m. a.s.l.) in tussock grassland and herbfield
Monoecious, creeping, glabrate to villous hairy, grey-green, perennial herb forming diffuse patches, or tight mats amongst tussocks and other herbs. Rhizomes at or near soil surface, stout, up to 2 mm diameter, somewhat wiry, dark, densely villous, glabrate, rarely glabrous; branches solitary, or in clusters of 4 radiating out from a flowering node, if solitary then arising if internodes are long; leaves initially clustered around shoot apex, often remaining crowded but sometimes spaced up to 20 mm apart. Short shoots absent. Roots extensive, wiry, much branched, up to 1 mm diameter. Leaves 1-pinnatifid, occasionally simple, 7-40 x 2-10 mm; blade up to 30 mm, elliptic, obovate, to broadly obovate, firmly coriaceous, dark green, sparsely to densely covered in greyish-white, villous hairs or glabrate, midrib not raised on ventral surface; pinnae 1-10 pairs, or absent, close-set or distant, cut to rhachis, linear to narrowly obovate, more or less cylindrical to flat, teeth usually absent, occasionally with 1-3 per pinna, these mostly on proximal margin, cut 1/2 across pinna, triangular, obtuse. Peduncles very much > leaves, 10-100 mm, ebracteate or rarely with 1 simply bract, desnely covered in villous hairs or glabrate. Capitula 4-8 mm diameter; involucre subcampanulate; involucral bracts 12-24, subequally 2- or more seriate, oblong, dark green to purple green, with 1-3 dark veins, with wide brown scarious margins, densely villous hairy to glabrate; pistillate flowers 12-200, 2.25-2.75 mm long, straight, yellow or yellow-red, often with 1-2 dark stripes along corolla and ovary; corolla much > than wide, dentition equal; staminate florets more numerous than pistillate. Cypsela 2.1 x 0.7 mm, golden-brown, compressed, biconvex, slightly to deeply wrinkled.
Leptinella pectinata subsp. villosa differs from L. pectinata (Hook.f.) D.G.Lloyd et C.J.Webb subsp. pectinata by its glabrate to densely grey-white, villous hairy rather than sparsely villous hairy or glabrescent rhizomes, leaves and peduncles, and yellow to yellow-red rather than white florets. From subsp. willcoxii (Cheeseman) D.G.Lloyd et C.J.Webb, subsp. villosa differs by its hairy (rather than glabrous), narrower leaves, bearing 5 or more pinnae (cf. 5 or less in subsp. willcoxii), and by the pinna which are linear to narrowly obovate (cf. broadly oblong to obovate). Distinction from L. albida (D.G.Lloyd) D.G.Lloyd et C.J.Webb is not always as clear cut, both species mostly differ cytologically, subsp. villosa is usually tetraploid and L. albida is diploid, but some populations of subsp. villosa within the range of L. albida are diploid as well. Otherwise both taxa differ in that L. albida is copiously covered in silvery-white, woolly hairs and subsp. villosa is sparsely to densely covered in grey-white hairs.
November - February
December - April
Easily grown in cultivation. Best propagated by division. Does well in a free draining, sunny situation. It does not relish excessive moisture and humidity.
leptinella: From the Greek word leptos (meaning slender, thin or delicate), referring to the ovary
villosa: From Latin (villus) meaning shaggy or hairy.
