118 BRYOLOGY OF NEW ZEALAND. 
in New Zealand (and, indeed, in the Southern Hemisphere) for Saelania 
glaucescens, as well as for several other rare New Zealand species. 
. curvirostre is generally recognizable by the fruit, which is: glossy, 
saptiyeeiiintt, when empty and deoperculate, gradually tapering clas 
wards from the rather wide mouth to the long well-marked neck of the 
plants, clear and we efined. e leaves are markedly carinate, 
generally tapering from some distance below the apex to a rather blunt 
point, and the margin (often one only) is usually rather mee 
reflexed near the base. Not unfrequently the cells, back of 
the stem between the leaves are all markedly papillose (var. ye 
Dixon); in the Mount Ida plant the nerve is finely scabrous at back, 
but it cannot be brought under that variety.

This very distinct plant appears to be rare. The type exists only in 
5; 
“near L. Wanaka, hah * and in Beckett’s hand is named “ Tridontiwm 
tasmanicum var. ‘Ba ngustatum.” This is certainly the same plant as 
Brown’s specimen. This locality is in the South Island. I have further 
— it from Mr. W. Gray as “ Fridontium tasmanicum, narrow-leaved 
orm,” gathered at Hastwell, Wairarapa, North Island, September, 1913 
(No 167), and January, 1914 (No. 201). Mr. Gray writes that it was covering 
two or three square yards of a eee Lek bank, on the side of a small stream, 
overhung by small trees. His specimens are much more robust than _ 
others, with larger, wider leaves, peer es enrolled when dry, m 
spreading when moist, a longer and narrower capsule, with the beak of f the 
lid shorter and stouter; but the structural characters do not seem to show 
any distinctions that would justify its separation from £. irroratum. 
The species is readily known by its very rigid, straight leaves, the long 
stout seta (varying from }in. to #in.) with rather large pac hyderm matous, 
castaneous capsule, when old blackish and often rather widely turbinate. 
The leaves taper, sometimes gradually, sometimes abruptly, from a wide 
subtriangular base to a long linear subula, scarcely narrowed to the 
incr , the margin crenulate and papillose. Tr tasmanicum 
has much wider, less id leaves, the nerve very much narrower, 
especially in proportion to the width of the leaf, a thickened margin, &e
