We spent about three weeks of July, 1912, together at Capel 

 Curig, Rev. E. F. Linton being also a member of our party for 

 ten days. The season was very unfavourable ; before our arrival 

 there had been six weeks of almost complete drought, which was 

 soon followed by three or four broiling hot days : then came 

 torrential rains, and, when these ceased, easterly winds prevailed, 

 accompanied by dense mist. Under such circumstances very 

 little work could be attempted on the higher hills ; and the 

 vegetation of the valleys (not specially rich in the district) was 

 rather backward and stunted : this applies particularly to the 

 Rttbi, which are numerous and interesting, but were mostly unfit 

 for collecting. A few apparently unrecorded plants (starred) were 

 observed; also some others in stations not mentioned in Mr. J. E. 

 Griffith's Flora of Anglesey and Carnarvonshire (1895). 



Thalictrum mains Crantz. Very scarce on the cliffs of Cwm 

 Idwal, above 2000 ft. ; strikingly different from T. minus L. 

 (collinum Wallr.), with which it is here associated, by its robust 

 habit, larger, more entire leaflets, and much longer, simple 

 pedicels ; it also flowers a little later, and no trace of fruit was to 

 be found on July 13th. 



Trollius europceus L. Sparingly near the head of Llyn Crafnant. 



[Meconopsis cambrica Vig. By an odd slip, this is ranked as 

 an alien in the Flora.] 



Corydalis claviculata DO. Near Capel Curig, and on a cottage 

 roof at Hendre, above Llyn Crafnant. 



Fumaria Bastardi Boreau (confusa Jord.). In cultivated 

 ground at Trefriw. 



Polygala oxyptera Reichb. In good quantity, and often very 

 fine, on a roadside bank between Bettws-y-Coed and Capel Curig, 

 near the Swallow Falls. — The large-flowered Milkwort of the 

 Cwm Idwal cliffs, referred to by Mr. Druce in Journ. Bot. 1902, 

 pp. 182-3, where he places it as a form of P. vulgaris L., and 

 mentions that Herr Freyn said it approached P. Saltelii Legrand, 

 11 sed erectior, floribus majoribus," appears to us to belong rather 

 to P. serpyllacea Weihe ; this species is frequent on mountains, 

 but restricted P. vulgaris, according to our experience, is usually 

 a low-ground plant. We did not see the Cwm Idwal form in 

 fruit, and unfortunately omitted to send home roots. It should 

 be tested by cultivation, as it is, at least in the wild condition, 

 most remarkable and handsome. 



Silene nutans L. In fair quantity on the hill above Deganwy 

 Castle ruins. 



Arenaria leptoclados Guss. Very characteristic, on a wall-top 

 at Gogarth, Great Orme's Head. 



Hypericum maculatum Crantz (dubium Leers). Abundant 

 about Capel Curig, especially by roadsides.
