This appears to be a perfectly distinct species, perhaps more nearly allied to 
G. Townson than to any other, but easily distinguished by the much smaller size, by 
often forming a compact sward, by the smaller narrower and much more numerous 
leaves, and by the smaller and fewer flowers. So far, it has not been seen except on 
the Mount Arthur Plateau, but it probably extends northwards to the high mountainous 
country at the back of Collingwood. y. 'FJo-

South Istranp: Nelson—Bidwill (n. 67 in Herb. Kew, jide N. E. Brown); 
abundant on the coast ranges near Westport, Mount Frederic, Mount Rockfort, Mount

A very beautiful plant, easily recognized by the tall slender strict stems, small 
uniform crowded leaves, which are almost black when dry, remote ascending cauline 
leaves, and rather dense umbels of large flowers.

Usually perennial, but often dying after flowering. Root stout, long and 
tapering. Stems simple or rarely branched from the base, stout, erect, 
terete, 6-20in. high. Radical leaves numerous, rosulate, 2—4 in, long, 
4-% in. broad, narrow oblong-spathulate or lanceolate-spathulate, obtuse or 
acute, narrowed into a short or long petiole, blade often channelled above, | 
I-3-nerved, coriaceous, rather thick and fleshy when fresh. Cauline leaves 
I or 2 pairs, seldom more, 3-2 in. long, linear-lanceolate or linear-oblong, 
sessile. Flowers large, 3-2in. diam., white, in large compact terminal 
umbels or cymes 2-6 in. diam. or more: pedicels slender. Calyx short, 
often less than 4 the length of the corolla, campanulate, divided from
