NOTES ON CARNARVONSHIRE PLANTS 
21 
Cvvm Idwal there are two forms of this plant, one with yellowish, 
the other with livid styles. The Oreadean hair-clothing is seldom 
well-marked in this species. 
H. argenteum Fr. Widely distributed but nowhere abundant. 
Streamside above Llanfairfechan. Hocks by Aber Fall; Foel Fras. 
H. cambricum F. J. Hanb. This is one of the most distinct of 
phyllopodous hawkweeds owing to its nearly glabrous foliage. This 
feature is seen even in the primordial leaves in early spring, when the 
plant at first sight might easily be referred to another genus. 
II. buglossoides Arv.-Touv. A very distinot hawkweed near this 
species, but with broader phyllaries, occurs on rocks near Deganwy. 
It was seen in some abundance in September, 1921, but by July last 
it had been nearly exterminated—not, it is to be hoped, by an 
Exchange Club collector ! Like Orchids and Orobanches, phyllo¬ 
podous hawkweeds should, for the most part, be sparingly collected. 
There is sad evidence of extermination at Clova and Ben Lawers. 
H. euprepes F. J. Hanb. Sparingly on Foel Fras (c. 2500 ft. 
alt.). Hocks above Llyn-an-Afon. 
II. irriguum Fr. Streamside above Llanfairfechan. Boulders in 
Cwm Idwal—a dwarf form growing with a similar state of II. vul- 
gatum Fr. This plant seems closely allied to H. diaphanoides 
Lindeb. 
II. sccinicum Duhlst. Great Orme’s Head (a stout form). Stream- 
side above Llanfairfechan. Near Ogvven Falls. 
H. sciaphilum Uechtrz. Common about Llanfairfechan on walls 
and railway-banks. 
II. Adlerzii Almq. The Menai Bridge station for this plant is 
now enclosed, but I obtained good specimens last July by climbing 
a high wall. These match the earlier British gatherings, and are 
very close to the Scandinavian material (Dalilstedt Hier. Exsicc. 
no. 85), albeit their cauline leaves are larger and less deeply toothed. 
H. Adlerzii seems allied to II. pinnatifidum Lonnr. and is rela¬ 
tively easy to distinguish owing to its slender rootstock, strict habit, 
sparse basal rosette, and remarkably large, elliptical cauline leaves. 
The plant distributed under this name through the Botanical Ex¬ 
change Club last year, and commented upon at page 587 of the 
Beport recently issued, is widely different and is identical with a form 
occurring: on the Great Orme which I refer to II. sccinicum. 
H. gothicum¥\\ With II. sciaphilum on walls at Llanfairfechan 
and by the streamside there (1905-1922)—a form with broad leaves 
and rather numerous heads smaller than those of var. latifolium. 
H. stictophyllum Dahlst. var. serpentinum W. H. Lint. Hocks 
above Llyn-an-Afon. 
Vaccinium Vitis-Idcea L. Carnedd Dafydd.— V. Oxycoccos L. 
Border of Llyn-an-Afon. 
Armeria maritima Willd. In this Journal for 1902 (p. 185) 
Dr. Druce records var. vulgaris for Crib Goch, Clogwyn dur Arddu and 
Glydyr Fawr, and in the Exchange Club Beport for 1915 (p. 203) he 
refers to having seen var. planifolia on Snowdon. This latter variety 
is abundant on Ysgolion Duon, occurring right to the summit of 
Carnedd Dafydd. I have also collected it on Clogwyn dur Arddu,
