Notothlaspi notabilis, Buch., n.s.

A small circular densely-leaved biennial (?) plant, with the inflorescence forming a terminal sphere of small white flowers; stem none; leaves numerous, ¾–1 inch long, spathulate, crenate on the upper half, sparsely covered on margins and surface with ribbon-like hairs, 1-veined, and pitted on the surface; scape, 1–2 inches long, hollow, apparently formed by the union of the petioles, thus probably relegating the leaves to flower bracts; pods, ⅓ inch long, obovate, with a very short style.

Hab.—Mountain range, head of Lake Ohou, 3,000 feet alt.—Buchanan and McKay, 1881.

Plate XXV. figs. 1, 2, plant nat. size, different views; 3, flower, 4, pod; 5, leaves, both sides; 5 a, portion of leaf much enlarged.

This remarkable little plant agrees in several details with Hooker's description of Notothlaspi rosulatum (“Handbook of New Zealand Flora”); that species, however, being described as a pyramidal fleshy herb, with a scape thicker than the little finger, and a span high, presents sufficient differences to claim for the present plant a distinguishing name. The illustrations given on pl. XXV. are drawn from the largest specimens in a collection of over fifty.

Hab.—Fine loose shingle slopes, where its fine thread-like roots penetrate to a considerable depth, presenting an unique botanical form in the Flora of New Zealand, the leaves being arranged like a miniature umbrella, surmounted by a small dense ball of white flowers.
