much on the tomentosa side, showing the influence of canina 
in the thinner pubescence and more simple serration of its 
leaflets, which also are more of the shape usual in canina. 
The fruit is not well-formed though none is quite barren as is 
usually the case in spinosissima hybrids. — A. H. Wolley-Dod. 
li. tomentosa is evident. The R. canina parent may be seen 
in the reduced secondary glandular serrations of the leaflets, 
and the reduction of the pubescence to a sparing amount on 
the midrib and secondary veins beneath, and in the oval 
shape of the small leaflets. — J. Fraser. 
Rosa [ dumetorum Thuill. var. Deseylisei (Bor.)]. By the 
Artro river, Llanbedr, Merioneth. Aug. 20, 1931. — Ida M. 
Roper. Certainly not Deseylisei. The single example sent 
to me is very like R. tomentosa var. scabriuscula Sm, but with 
short peduncles and decidedly hispid styles. I should so 
label it tentatively, though if I had seen the whole gathering 
I might have given a different opinion. If any member 
doubts this name and will send me his specimen I will amend 
the name if it seems desirable.— A. H. Wolley-Dod. 
Rosa [tomentosa var. cuspidatoides Crep.]. Nant Francon, 
Carnarvonshire, Aug. 26, 1931. — Ida M. Roper. (One sheet 
for naming). This is very obvious R. rubiyinosa ; see the 
acicles beneath the inflorescence, the shape and dentition of 
the leaflets and their intense glandular development. Doubt- 
less when fresh they had a strong Sweetbriar odour. — A. H. 
Wolley-Dod. 
Sorbus Aria Crantz, var. lanifera Kerner. A solitary tree 
on the border of a limestone wood near Clevedon, N. Somerset, 
v.c. 6, June 15, 1931. — J. W. White. This quite agrees with 
specimens collected by Augustin Ley in Leigh Woods, N. 
Somerset, 1892, and now in the herbarium of Dr. Hedland. — 
J. Fraser. 
Callitriche intermedia, Hoffm. var. lacustris Williams forma 
Halleri (see Williams Prod. p. 509). Ditch, Mitcham Common, 
Surrey, May 10, 1931. [C 157]. A few fruits are present. 
A month later the ditch had been cleared out. — J. E. Lousley. 
Callitriche intermedia Hoffm. [2631]. Roadside ditch, 
Sharpham Peat Moor, Somerset, v.c. 6, June 26, 1931. — 
H. S. Thompson. This is correct, I think. An extremely 
variable species. — W. H. Pearsall. Of a series with linear
