Bucuanan.—On the Alpine Flora of New Zealand. 845 
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 pene- 
trate 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. 
Hectorella cespitosa, Hook. fil. 
Handb. N.Z. Flora, vol. i., p. 27. 
Leaves densely imbricated round the stem, Spreading, variable in form 
and size, linear-acuminate, or oblong-obtuse, eous and much dilated 
at the bottom, entire. Flowers of two kinds, seoalonk with stamens only ; 
sessile among the uppermost leaves, white or sometimes pale salmon 
colour; pedicel with 2 bracts at the base; sepals 2, ovate acute, continuous 
with the pedicel ; petals 5, united at the base, erect and thickened beneath 
the tip ; capsule not seen. 
Hab.—This beautiful alpine is found abundantly on Mount Alta, where 
it may be seen in large patches on steep, rocky places, at an altitude of 
5,000 feet. 
A marked feature in this plant, and which adds much to its floral 
beauty, is the arrangement of the flowers in circles at the ends of the 
branches, many of the patch plants having only one terminal flower on 
each branch.

Plant, }-1 inch high. Leaves long, petioled, numerous, rising from a 
small rhizome, ovate, generally 3-lobed, petioles forming a close bundle. 
Scape longer than the petioles, involucral leaves linear-oblong, acute, 
connate at the base. Fruit linear, scarcely 7; inch long, much longer than 
its pedicel, 5-ribbed, ribs terminating in unequal-sized hooked teeth. See
