much more luxuriant than the wild form of the Great Orme, 
which is frequently quite dwarf. In “Journ. Bot.” 1909, p. 12, 
the late Augustin Ley described a variety sub-britannicurn of 
H. stenolepis Lii.deb., citing the Great Orme as one of its localities. 
I do not know whether in his opinion the Great Orme plant 
previously referred to II. britannicum belonged to his variety, 
or whether two distinct plants occurred. But Mr. Bickham’s 
specimen seems, from the hair-clothing of the foliage, to be 
II. britannicum , of the section Oreadea , and not a form of • 
II. stenolepis. — H.W.P.

Sonchus arvensis L. (Ref. No. 354 a & b.) Rough cultivated 
ground near Petworth, W. Sussex, v.c. 13, Sept. 17. 1918. — 
W. C. Barton. The specimen labelled 354a may not be var. - 
glabrescens G. G. and W. which, ( teste Williams’ “ Prod.”), has 
eglandular peduncles and phyllaries, but it seems to come 
satisfactorily under var. laevipes Koch, who says in his “Synop,” 
ed. 3, 1857 (the var. dates from ed. 2, 1844), “ pedunculis glabris 
involucris subhispidis vel pedunculis involucrisque glabris.” This 
must not be confused with Grenier and Godron’s laevipes (“FI. 
Fr.”) of later date (1850), which is evidently the same as 
glabrescens. However, as Mr. Barton truly remarks, these varieties 
are only matters of degree. — C.E.S. 
Primula elatior Jacq. x vulgaris Huds. On boulder clay, 
Hardwick Wood, Cambs., v.c. 29, May 20, 1919. In his paper 
on “ Primula elatior in Britain,” read before the Linnean Soc., 
17 June, 1897, Mr. Miller Christy, F.L.S., states that the 
boundary line between the oxlip area and the primrose area runs 
through Hardwick Wood. On this line the hybrids between the 
two species are plentiful. Of the parents the oxlip is the more
