… Plagiobryum demissum Lindb: — Mont Dolin above Arolla at an 
altitude of about 8500 feet, c. fr. 
 Webera cucullata Schp. — Pas de Chèvres above Arolla at an 
altitude of about 8000 feet, a tall sterile form about 3 inches high 
with rhizoids only in the lower portion of the stems and appa- 
 rently very close to, if not identical with, the var. Z/ausmanni De 
Not. 
 Bryum Mildeanum Jur.— A very slender form with a few » flo 
wers and bearing an illusory resemblance to 2. Claviger Kaurin 
in the field occurred by the Navigenze near Zinal. — B. Blindii 
Br. Eur. Sandy margins of the Navigenzé near Zinal, c. fr. 
 Mnium medium Br. Eur. — Earth among shaded rccks by a 
_stream at Grimentz, c. fr. — M. lycopodioides Hook. Earth among 
_ rocks, Alpe Tracuit, Zinal; à small form mostly of the © plant 
and with only two capsules. Except in size, however, it agrees 
. well with the plant abready recorded from Les Plans. 
 Leucodon sciuroides Schwgr. — Tree trunks at Bévieux near 
Bex,.c: fr, | 
Myurella julacea Br. Eur. var. scabrifolia Ldb. — Rocks tothe 
west of Zinal ; a well characterized form of the variety. The type 
_ Was fruiting near Arolla. E 
_. Pseudoleskea patens Lab. — Near the Glacier des Ignes, Arolla ; 
a rather robust plant with the leaves less papillose than usual. 
À more normal form occurred on the Roc de Ja Vache, Zinal. — 
Ps. atrovirens Br. Eur. var. fllamentosa Boulay. Rocks near Les 
Plans, a very slender form of the variety. — Ps. radicosa (Mit) 
= Rocks on the Col de Sorebois above Zinal at an altitude of abou. 
8000 feet. Dr G. N. Best, to whom I submitted this plant says that 
_ itis plainly Ps. radicosa (Mitt.) and « quite near the typical 
form of this species which is wide Spread and variable both in 
Europe and America ». Ps. radicosa is not generally recognized 
in Europe, though probably à large proportion of the plants 
usually referred to the var. brachyclados of Ps. atrovirens should 
be referred here. The substantial identity of the European and 
North American forms of this genus is a fact of some interest, 
though it is much obseured by their rather unfortunale treat- 
ment in the text books. The North American forms of the genus 
= have recently been ably treated by D' Best in his « Revision of 
_ the North American species of Pseudoleskea » (Bull. Torrey Bot. 
_ Club, May 1900). FE Le 
 Brachythecium collinum Br. Eur. — Mpe de l'Allée Zinal, Hau-_
