great variation of P. Aria is often simply due to an open or close 
condition of the soil. On the chalk downs leaves from the same 
tree may exhibit considerable differences. The specimens sent 
are not enough for good determination. Collectors must remem- 
ber that the more critical the genus the better the specimens 
required. — A.B. 
In “Journ. Bot.” 1916, p. 10, Marshall pointed out that he 
agreed with Dr. Hedlund and with Fries (and Nyman) in regard- 
ing Sorbus as “ naturalissimi hujus generis”; and that it is 
difficult to see why this group should be ranged with the apples 
and pears in view of their marked difference in flowers, fruit and 
foliage. Sorbus is also adopted by Keller and Schinz, by Rouy, 
by Coste, and by Holmboe, to mention merely four modern 
authors whose works are by me. I regret the confusion some of 
my numerous gatherings were in, and that I left it too late to 
get Mr. White’s help with them. — H.S.T. 
Sorbus near latifolia Syme [2426]. Top of cliff, south 
of Nightingale Valley, Leigh Woods, M. .Somerset, v.c. 6, May 
30, 1922. Flowers in dense corymbs, small (12 mm.). Tomen- 
tum slightly yellowish grey on leaf-veins. A very ornamental tree.

fruit ? — C.C.L. P. latifolia Syme = var. dedpiens Bechst. —

S. Aria (L.) Crantz. sensu latiore [2420]. Large-leaved form, 
with large flowers 22 — 23 mm. across. Top of cliff, south of 
Nightingale Valley, N. Somerset, May 25 & 30, 1922. — H. S. 
Thompson. The dimensions of the flowers which Mr. Thompson 
gives are certainly unusually large. It would be interesting to 
know if the size is constant, or was due to the extraordinarily 
exuberant year of 1922 as regards the flowering shrubs. — J.G. 
A broad-leaved form, and not quite the common one. — J.F. 
S. Aria (L.) Crantz. forma [Ref. C.]. Cheddar Gorge, top of 
cliff, south side, N. Somerset, June 1, 1922. Leaves long and 
nearly oval. Veins very prominent. — H. S. Thompson. S'. Aria.

S. Aria (L.) Crantz., near var. indsa Reichb. [2421], Top of 
cliff, south side of Nightingale Valley, N. Somerset, v.c. 6, May 
30, 1922. Leaves oval, small. From the same tree as my [2222] 
June 1916, thus named by E. S. Marshall. — H. S. Thompson.
