PHANEROGAMS AND FERNS OF SOUTH ARDGOIL. 29 
Decumbent Heath-grass (Zriodia decumbens, Beauv.) — 
Frequent in drier parts of pastures and on banks, from sea- 
level up to about 700 feet. 
Fir Club-moss (Lycopodium Selago, Linn.)—Frequent on 
rocky ground from 1000 feet upwards, but occasionally lower 
(800 feet), and ascending to the summit, or near the summit, 
of all the higher hills, 
_ Savin-leaved Club-moss (Lycopodium alpinum, Linn.)—Not 
widely spread, but locally plentiful above 1500 to 2000 feet, 
especially on ridge between Carn Glas and Cnoc Coinnich, and 
on the col between The Brack and the Cnoc. 
Lesser Alpine Club-moss (Selaginella selaginoides, Gray)— 
Frequent on wet rocks and among wet vegetation, especially 
near streams ; from 450 up to 2000 feet. 
Smooth Horse-tail (Hquisetum limosum, Linn.)—Forms a 
belt round the north half of the Lochan. 
Wood Horse-tail (Lquisetum sylvaticum, Linn.) — Among 
grass near the Lochan, but not noticed elsewhere. 
Royal Fern (Osmunda regalis, Linn.)—At one time frequent 
up the allts, from which roots were taken which now adorn 
many of the gardens at Lochgoilhead. A diminutive specimen 
was found at 800 feet in the Garbh Allt. Roots were gathered 
in 1910 opposite Carrick Castle. 
Common Polypody (Polypodium vulgare, Linn.)—Occasional, 
but not common ; in dry places up to 1750 feet. 
Beech Fern (Polypodium Phegopteris, Linn.)—Very frequent, 
especially at mid levels, in shady places on banks, and among 
rocks up to 2000 feet, but less frequent at low levels. 
Oak Fern (Polypodium Dryopteris, Linn.) — Occasional in 
the wooded allts up to 700 feet, in wet mossy places, where 
it is generally well developed. 
Parsley-fern (Allosurus crispus, Bernh.)—A trace only on 
the rocks of Ben Reithe about 2000 feet up. 
Holly-fern (Aspidiwm Lonchitis, Sw.)—Below rocks ; about 
1000 feet on the west slope of Cnoc Coinnich, 1500 and 1750 
feet on west face of Ben Reithe, and probably more common, 
as its habitat makes it somewhat elusive. 
Prickly Shield-fern (Aspidium aculeatum, Sw.)—Forms of 
this fern are very frequent on rocks in streams where spray 
reaches, but the type form does not occur, the commonest 
form approaching var. lobatum, Sm., up to 2000 feet; var.
