54 BRYOLOGY OF NEW ZEALAND. 
This species has not, I believe, been gathered again since collected by 
R. Brown in the “ old bed of River Waimakariri.” It is much to be desired 
that this and the pipeine species should be rediscovered and further 
studied.

When I first examined the type of W. Brotherusii in Brown’s herbarium, 
and at once detected the close relationship between it and the foregoing 
plant, I supposed that I had to do with the same species, and that the differ- 
ence in the form of capsule was accidental or varietal merely. Further 
examination, however, convinced me that I had to do with a distinct species. 
et of W. Bro therusié i in Brown’s collection is a well-grown tuft with 
between 30 and 40 et all of identical form and position, with no 
tendency to resemble those of Ps. Buchanani. Closer examination also 
showed that the leaves exhibited constant differences: the nerve very 
markedly wider, the cells of the expanded part of the leaf somewhat looser 
and more irregular, the upper distinctly different, not sstcalagagg, but 
shortly rectangular or elliptical, and the leaf-apex quite entire. 
e seta is in several instances decidedly flexuose, or in others 
this a not marked ; the capsules are inclined, very small, scarcely 1 mm 
in length, waked elliptical, quite smooth, equal at base, and neither taper- 
ing into the seta nor strumose. 
The sees tee is pce leptodermatous, the exothecium cells elongate 
hexagonal, rather lax and scarcely incrassate, the rim thickened and dark 
reddish-brown, of two or three rows of short, more incrassate, deeply coloured 
cells. Stomata ng r to be present at the extreme base of the capsule. 
iffers from Ps. austro-georgicum in the leaf-form as does 
's. Buchanami, in the longer upper cells, entire points, and the capsule, 
which is much smaller, shorter, oval rather than oblong, and symmetrical 
or almost so, not curved or gibbous. 
SELIGERIA Bry. Eur. 
A small genus of minute mosses, all the species with the exception of 
the single New Zealand representative being confined to the Northern 
the plants has probably led to their being overlooked, and it is probable 
that further species will be detected in the subantarctic and antarctic 
regions.

R. Brown described and figured the above species in the volume cited, 
from “Limestone rocks, Castle Hill, Mar., 1891 ; We ka Pass, limestone 
rocks, Mar., 1893 ; Oamaru, 1897. Coll. R. Brown.” Curiously, Brown’s 
herbarium contains no specimen under this name, but the plant exists there 
under the MS. name “ —“ — calearea,” from “Castle Hill, West Coast 
ad; coll. R. Brown.” minuteness of the plant has baffled Brown’s 
draughtsmanship, a os figtitee on tab. 41 are rather misleading: the
