Hymenanthera obovata, n.s.
An erect glabrous shrub 4ft.—8ft. high, with pale bark, sparingly branched, branches ascending. Leaves in the young state obovate-cuneate, 3-lobed, membranous; mature 1in.—2in. long, coriaceous, obovate or oblong, narrowed into a slender petiole below, retuse, margins slightly recurved, quite entire. Flowers not seen. Fruits as in H. crassifolia, Hook. f., but slightly larger.
Hab. South Island: Nelson—On limestone rocks, Graham river; Mount Owen; T. F. Cheeseman! On limestone rocks between Takaka and Riwaka; T. Kirk. Canterbury—On limestone rocks, Broken River basin; J. D. Enys and T. Kirk (1876): Ashburton Mountains; T. H. Potts! 2,000ft.—3,000ft.
This puzzling plant appears to be closely related to H. oblongifolia, A. Cunn., of Norfolk Island, the leaves of which are said to be denticulate, and of greater length. A common state of H. crassifolia, Hook. f., approaches our plant in some respects, but the leaves are smaller and almost sessile. The leaves of the young state of our plant show that, notwithstanding its different appearance, it has, direct relationship with H. latifolia, R. Br. Baron Von Mueller's remarks on Hymenanthera, in his “Vegetation of the Chatham Islands,” may be read with advantage.
