306 BRYOLOGICAL NOTES FROM THE WEST HIGHLANDS. 
A stream near Tyndrum yielded several interesting plants, * 
Orthothecium c.fr., Hypnum stellatum var. protensum ‘c.f, eu 
gyrium var. Mackayi, Isothecium myurum var. robustum. Also one 
or two forms of Dichodontium, which, with the Weisia (Hymeno- 
stylium) before on deserve fuller treatment, and must not 
be dealt with her : 
en Douran oat Doireann), which is in Argyllshire, is 
easily ene from Tyndrum, and still more so from Bridge o 
carpum var. a = Dixon, Se the aad locality for this last

On the 98rd ae athe! from _— ne et agp striking 
due east for the gap between ae Douran and Ben an Dothaidh, 
and then following up the str m which r ni ear cee ae in a 
some interesting mosses, among them being various forms of Hyp- 
num exannulatum, with which some of the pools were almost filled. 
e most prominent was a fine submerged form of the var. steno- 
phyllum Hobk., (Group Rote, var. falcifolium Ren.). Another 
noticeable form, and quite e distinet — is, was one referable to 
e var. brachyd — Ren., the forma orthophylla of 
mense masses of nas sarmentosum filled some of the 
H, sarmentosum and palming off its capsules upon it. 
One of the most interesting — we gathered here was @ 
floating form of H. trifa rium, some of the stems collected being as 
as a foot in ‘length, without a — ch. The moss may be 
where a bog is attempting, with indiffe ne success, to pose as @ 
stream ; but, however good the specimens in such habitats may look 
in situ, they mostly disappoint in the fruition, and rarely make nea 
herbarium specimens; here, however, clean and unbroken speci- 
mens could be obtained without much difficulty, eight or nine 
inches long, eed even more. 
Plagiothecium Miillerianum a — in aed good condition on 
cree: quite low Bhs and t the summit. Webera
