(1914). (Plockton, Ross-shire ; Sept. 1913.)—I do not understand 
on what characters this is based, except on the long corrugated leaf- 
points. It seems to me a very ordinary form of H. molluscum , 
which frequently has the subula crinkled—much more so, very often, 
than here.

(near); Sept. 1901). (Var. minus culum\ Ben Lawers; 1864. And 
many others.)—These are all forms of H. molluscum , some or most 
being var. condensatum. 
H. recurvulum Stirt. in Ann. Sc. N. H. ix. 180 (1900). (Largs, 
Ayrshire; 1869; on boulders near sea.)—This is a lax form of 
Ceratoclon purpureus. There is a single pure tuft, so that there is no 
question of a mixture of plants. The description, it will be found, 
is quite applicable. 
H. teichophilum Stirt. in Ann. Sc. N. H. xvi. 177 (1907). 
(Garscube, near Glasgow; 5 Nov., 1906.)—This cannot be separated 
from II. cupressiforme. 
SUDRE’S ‘RUBI EUROILE’*. 
By the Rev. H. J. Riddelsdell, M.A. 
Several points leap to the mind at once, on a first glance at this 
volume. One is, of course, the beautiful get-up. Making allowances 
for an inevitable bulkiness—it is no hand-book—the absolute clear¬ 
ness of print and of arrangement, and the delightful drawings (which 
constitute more than half the bulk) immediately bespeak favour. 
There is a completeness about it which in no way detracts from its 
ready usefulness. 
Then, again, the diligence that lies behind such a piece of work is 
staggering 1 to the imagination. The introduction is not dated: but 
the volume (which is not dated) was published in parts at intervals 
from 1908 to 1913. If the introduction was written in 1908. then 
it was in 1893 that Sudre began the study of Rubus : and the 
whole volume is the result of only twenty years’ work. Dried speci¬ 
mens were diligently amassed from nearly all the countries of Europe ; 
he must have examined enormous numbers of them; seeds were 
planted and grown on ; the literature of the subject was worked 
through; and numerous preliminary studies published. 
Once more, there can be no doubt of the originality of Sudre. 
He was never content to accept a view. He was never afraid to give 
his own opinion. And, moreover, there is much to say for his 
arrangement and grouping of the European forms. He has got hold 
of some good leading ideas, e.y. the condition of the pollen in a 
given form, the area of its distribution, and so on ; and used them to
