Orthothecium intricatum B. et S. — In hollows of boulders, 
Pochten Kessel, Adelboden : a form with crowded axillary fili- 
form brood-branchlets, resembling those of Plagiothecium 
… Müllerianum. 
Brachythecium glaciale B. et S. — Kindbettighorn, Wildstrubel, 
REVUE BRYOLOGIQUE - A 
2750 m. B. A rather usually strict form, with the leaf-points 
broad and rigid, and the cells short. 
Eurhynchium striatum ©. brevifolia Zett. — Choleren Schlucht, 
Adelboden. This form is very different in appearance from f. ion- 
gifolia Zett., which alone, so far as 1 am aware, occurs with us 
in Great Britain. 
E. murale var. julaceum Schp. — Boulders, Gilbach, Adelboden. 
Amblysteqium curvicaule Lindb. — Engstligen Falls. Growing 
with a form of A. filicinum, and at first sight appearing to inter- 
grade with it; but closer examination showed that this was not 
. the case, and the differences, though somewhat hard to define, 
were marked, and as far as 1 could see, constant. Some of the 
plant was well marked var. strictum mihi, but transitions 
occurred between it and the type. , 
 Hypnum falcatum var. virescens Schp.— Submerged in stream, 
Butschialp, Adelboden. Pretty clearly only à submerged form of 
H. falcatum, which grew beside the same stream. 
H. cupressiforme var. subjulaceum Mol. — Pochten Kessel and 
Engstligen Falls, Adelboden. 
H. dolomiticum Milde. ». — À puzzling plant, forming large 
rather deep patches on the roots of a spruce fir, Engstligen Falls, 
Adelboden, appears to belong here. With most of the characters 
of A. fastigiatum, it is clearly dioicous, » flowers alone occur- 
ring. D' Culmann points out slight differences in the leaf charac- 
ters from }J. dolomiticum, the leaves being a little narrower and 
less suddenly acuminate, with somewhat shorter cells, but these 
can, I think, hardly be looked upon as characters of great impor- 
tance. D' Culmann remarks that the stem section certainly agrees 
with that of A. dolomiticum, rather than with that of /Z. fastigia- 
tum, a character to which he is inclined to attribute considerable 
weight, but on account of its sorticolous habitat, — H. dolomiti- 
cum not having yet been recorded as growing on trees, — he 
hesitates Lo assign it to that species. 
The importance or otherwise of the station (corticolous or rupi- 
varyÿ in different genera Or £group of species ; in Ulota it would 
_colous) as a separating character must without doubt be held to 
have very great value, in Anomodon scarcely any. It is perhaps A 
worth while pointing out that the habitat in Drepanium is ofa
