Nemcia effusa (Fabaceae : Mirbelieae), a new species from south-west Western Australia, and a key to Nemcia
CRISP, M.D. AND MOLLEMANS, F.H.
A new species of Nemcia, N. effusa Crisp & Mollemans, is described from the north-west part of Lake Grace shire, south-west Western Australia. The species is quite distinct with no clear affinities. It is named for its habit with rigid, diffuse stems and branchlets. In some respects similar to N. stipularis (Meissner) Crisp, it differs in the leaves spreading widely and being broader(3-4 mm) and impressed-punctate below, and with stipules shorter (2-3 mm). It is also similar to N. punctata (Turcz.) Crisp in the leaves being impressed-punctate below, but differing in having conspicuous stipules and longer leaves (1-2.5 cm) that are spreading widely but scarcely recurved. Only two plants of N. effusa were found at the type locality, and the species was not observed elsewhere during surveys of remnant vegetation (by the second author) of c. 71,250 km² of the southern wheatbelt region of Western Australia. This suggests that N. effusa is neither widespread nor common.
