acteiizes most recent continental monographs; but in other respects 
this is an excellent piece of work. 
The Trees of Great Britain and Ireland, by H. J. Elwes, 
F.R.S., and A. Henry, M.A. Vol. III. Edinburgh, privately printed, 
1908, pp. vi, 451 — yiij plates. Nos. 127 — 207. Includes Carpinus 
Betulus with a var. qucrcifolia, Desf., in Cawston Parish, near 
Aylsham, Norfolk. Also var. incisa, Alton, Beaufort, Sussex ; 
Smeaton, Hepburn, East Lothian. Arbutus Unedo, L., with var. 
rubra, Alton, noticed by Mackay on Red Slate near Glengariflf. 
Pinus sylvestris, L., var. scotica, Elwes and Henry, differs in the 
redder bark of stem, in the shorter and more glabrous leaves 
(i^ inches) often persistent for four years, and in the shorter cones, 
inches long. Acrr Pseudo-platanus^ L., with a pyramidal sport 
(var. pyramidalts, Nicholson), which originated in a grove of trees 
at Newby, and several variegated forms are also described. It 
is stated that as yet no fossil remains of the Sycamore have been 
noticed in Britain, and Clement Reid thinks it was introduced by 
the Romans. The last British tree described is Acer carnpestre, L., 
undoubtedly native in England. The iHustrations of the trees 
mentioned are very good. 
Trees and their Life History, by Percy Groom, M.A., 
D.Sc. 4to., pp. XV, 407. Price 2^s. nett. Cassell & Co. A charming 
and useful book with beautiful illustrations. 
The Subsection Eu-Caninae of the Genus Rosa, by Major 
A. H. VVolley-Dod, published in ‘ Journ. Bot.’ 1908, and issued as a 
supplement. This is a painstaking investigation into the members 
of the Canina group, which will be found very useful to students 
of that puzzling assemblage. The life-long labours of our late 
expert, M. Cre'pin of Brussels, have scarcely received their due, 
and M. Deseglise, whose arrangement of the genus was anything 
but natural, has been allowed to take the premier place. It is to 
be hoped our member. Major Wolley-Dod, will continue his 
researches, and allow us to have the benefit of his industry and 
knowledge.
