Leptinella intermedia (D.G.Lloyd) D.G.Lloyd & C.J.Webb
n = c. 78
A small creeping perennial herb with tufts of leaves in turf. Rhizomes shallowly buried, initially dark, flexible, and sparsely pilose, becoming pale stiff and glabrous; branches uncommon, us. single at flowering nodes; leaves spirally arranged, 1-2 at the apex, 0.5-1.0 cm apart. Short shoots grow ± upwards from the rhizome, with up to 5 tufted leaves at the apex. Roots slender and weak, up to 0.6 mm diam. Leaves 1-pinnatifid, 0.8-4.0 × 0.2-1.2 cm; blade 0.4-3.0 cm long, elliptic, coriaceous, light green, sts with brown pigment especially on proximal pinnae, glabrous; midrib sts slightly raised on ventral surface; pinna 4-10 pairs, not overlapping, cut to rhachis, elliptic; teeth us. few per pinna, up to 5 on distal margin and 3 on proximal margin, cut up to ½ across pinna, triangular, obtuse. Peduncles us. borne on rhizomes, ca. equal to leaves, ca. 3 cm, ± villous, nude or with 1 simple bract. Monoecious. Heads 4-5 mm diam.; surface convex; involucre hemispherical, phyllaries ca. 12 in 1-2 subequal rows, broadly elliptic, dark green, ± villous, with wide brown scarious margin, not growing after anthesis; pistillate florets few, up to 10 in 1 incom- plete row, ca. 2.0 mm long, almost straight, yellow-green; corolla slightly longer than wide, with almost equal teeth; staminate florets much more numerous, ca. 40. Achenes up to 1.3 × 0.9 mm, compressed, biconvex, golden brown, unwrinkled. Probably flowers principally in summer.
Rhizomata leviter defossa. Folia coriacea, ± glabra; pinnae non imbricatae; dentes pauci, triangulares, obtusi, plerumque in distalibus marginibus pinnarum. Monoica.

Notes
editorial
Given (1976) included L. intermedia, and it is mentioned in his 1981 book. Himmelreich (2012) reports it as having sequences matching the “dioica group” and not supporting the putative parentage given by Lloyd (1972) (no trace of L. pectinata according to Himmelreich 2012). Lloyd suggests it as an allopolyploid (ie, species of hybrid origin) rather than as a hybrid as such and points out that the chromosome number of 78 is not consistent with in situ origin since the L. pusilla and L. pectinata at Hakataramea each gave counts of 52. More studies are required!
