Thalictrum ? Dyffryn Crawnon, Brecon, 25th Sept. 1908 ; 
and Craig Cille, Brecon, 14th July and 24th Sept. 1908. Tlie 
Rev. E. F. Linton reports this plant to be T. mimis^ L., d. pubescens, 
Schleich. In both localities on mountain limestone ; at a height 
of from 1,500 to 1,700 feet. — A. Ley. Apparently a form of T. 
minus, L., var. collinum (Wallr.). This var. occurs in quantity on 
the mountain cliffs of South Wales. I have it from Craig-y-llyn, 
Glam., Craig Cil-le. Breconshire; Llyn-y-fanfach, Caermarthenshire ; 
and always quite glabrous. The Dyffryn Crawnon plant differs 
from these in being finely pubescent nearly all over (not glandular, 
as far as I can see, and therefore not, I presume, var. pubcscens, 
Schleich.), The same feature occurs to a less extent in one speci- 
men (out of two) gathered in 1896 at Barden Tower, by the River 
Wharfe, v.-c. 64, Mid-West Yorks. 1 do not know of any name 
for the var. — H. J. Riddelsdell. 
T. flavum, L. Thames meadows, Godstow, Oxon, Aug. 1908. 
I send this in order to obtain tlie opinion of different botanists as 
to its varietal name. It is fairly uniform in character over the large
