68 BRYOLOGY OF NEW ZEALAND. 
No specimen can be found of Dicranum waimakaririense in R. B 
collection, but from the cescetion and figures it may, I think, very satel 
be referred here. 
The capsule in D. Jamesonii is not, properly speaking, strumose (cf. 
Handbook, p. 411, sub D. Schreberi), but when tek capsule is dried before 
maturity a substrumose ring is formed at the n 
meson appears to J widely distributed in New Zealand. 
C. Miiller’s specimen of Aongstr. subredunca bears a few subglobose or 
elliptical gemmae arising pathy ga rhizoids on the stems. They are 
articulate, smooth, orange-brown. I have described and figured almost - 
exactly similar ones on D. heteromalla from Madeira (ef. Journ. Bot., 
October, 1909, t. 499), and they occur also on species of Barbula, and 
frequently on Leptobryum pyriforme Wils.

Paris cites this species as Anis. gracillimum Mitt., while C. Miiller 
himself refers to it in Gen. Muse. Fr. ( 901) as Aongstr. gracilima .sp. It 
was, however, described and figured by Beckett as quoted a 
n 
be cited as of C. M. & Beckett. It stands in C. Miiller’s herbarium as 
“* Aongstr. gracillima C. Mill., N.Z., Pine Hill, Dunedin, leg. W. Bell,” and 
— same citation is given in Hedwigia (loc. cit.), Does that the reference 
. n. sp. "is a slip merely, and does not refer to another 
e two species of Dicranum described by R. Aw which are here 
pe in the synonymy of D. gracillima are not in his herbarium, but I 
do not think there can be any question that they represent two forms of 
this plant differing slightly in size, the only difference suggested by his 
description being that the calyptra covers the greater part of the SS ie In 
D. pusillum, while it scarcely covers the operculum in D. pygmaeum 
D. gracillima i is known by its very small = slender habit, it leaves, 
and minute, erect, and symmetrical capsule, somewhat wide-mouthed when 
dry. The cells, especially in the lower Hives as are : aiebadiy wide and thin- 
walled, and are all elongate ; and the nerve is much weaker than in most 
species. It is not unlike the European D. rufescens Schimp. 
The known localities all lie, I believe, in the South Island.

C. Miller refers this species to Weisiella ; but the capsules are decidedly 
and asymmetrical, the mouth wide, the peristome large and well
