Art. XLI.–Additions to the Flora of New Zealand.

[Read before the Wellington Philosophical Society, 9th December, 1882.]

Plate XXVIII.

Hymenanthera traversii, Buchanan.

A Small glabrous, branched, shrub-tree. Branches rigid, reddish-brown, rough, with viscid secretion; leaves coriaceous, alternate, olive-green, shortly petioled, ¾-1 inch long, obovate, obtuse or acute, covered closely on the back with small silvery-white tubercles, margins reflexed, venation obscure, midrib distinct, stipules very small.

Flowers very small, solitary, in the axils of the upper leaves; pedicels short, curved, with small bracts at base; calyx cupular, entire; petals ⅛ inch long, linear obovate or linear oblong, obtuse.

This addition to the flora of New Zealand was discovered in the bush, Collingwood district, Nelson, by Mr. H. H. Travers, while on a recent visit there. As an ornamental foliaged plant it may be commended, but from its diminutive inflorescence it can hardly claim a place in the flower border.

Metrosideros parkinsonii, Buchanan.

A large robust climbing shrub with the terminal twigs 4-angled, whole plant glabrous. Leaves distichous, shortly petioled, 1½-to 2 inches long, oblong-lanceolate acute, midrib prominent, lateral nerves indistinct. Flowers numerous in robust little cymes which grow from the branches,

but are never axillary to the leaves, peduncles and pedicels rigid, stout. Flowers, including stamens, 1 inch long. Calyx pyriform widening at the mouth and produced beyond the ovary, lobes triangular, petals large, bright-crimson, oblong acute, lacerate on the margins, stamens and style stout. Ovary adherent only at base to the calyx-tube. Capsule 3-valved, upper part free.

This plant differs from M. hypericifolia (to which it is allied) in its larger size, upright habit of branching, smooth bark, and position of capsule in the calyx. From M. colensoi (to which it is also allied) it differs in the cymes never being axillary to the leaves, and in the free position of the capsule in the calyx-tube.

Named in honour of Mr. Sydney Parkinson, botanical draughtsman on Captain Cook's first voyage to New Zealand. Collected in the Collingwood district, Nelson, by Mr. H. H. Travers, December, 1882.

Calochilus paludosus, R. Br.

The present plant adds yet another genus of Orchideœ to the flora of New Zealand.

It was collected by Mr. H. H. Travers in the Collingwood District, South Island, in December last. Baron F. von Müeller, to whom specimens were sent, says: “I took immediate notice that this Calochilus might be identical with C. paludosus, as you suggest, but the inner segments of the calyx are shorter, and the anther is less blunt; still, that may be ascribed to variation, and I must confess I am not clear about positive distinction between C. campestris, C. robertsoni, and C. paludosus, perhaps because only one form seems to have come under my notice in Victoria in the fresh state, and the others I know only from dried and not very instructive New South Wales specimens. It would be well if a little more material of the New Zealand congeners could be procured, and best of all if several flowers were put fresh into alcohol.”
