with glandular hairs.” There is thus a general consensus of opinion, 
at home and abroad, that C. tetrandrum should be provided with 
glandular hairs in more or less abundance ; and it was only when 
Colonel H. H. Johnston sent me, last year, a line series of what was 
undoubtedly this species from the Orkneys, that I saw that this 
diagnosis could not cover some of his gatherings. These plants, which 
are often of a different shade of green from ordinary tetrandrum 
(owing to the non-adherence of dust, particles of sand, etc.), may, 
I think, be separated as var. eglandulosum with the following 
diagnosis :— 
Caules pedunculi calycesque hirti non glandulosi; caetera ut in 
typo. 
As if to make up for the loss of the glands, those plants that lack 
this protection seem to produce as a rule a greater abundance of 
longer simple hairs than in the type. The variety is probably not 
uncommon ; I have seen specimens from the following localities :— 
v.c. 2. Corn wall, E. ; wall top, Tregantle, near Antony. T. R. A. 
Briggs, v.c. 9. Devon, S.; wall near the Hoe, Plymouth ; near 
Mount Batten, Plymstock; Blaxton, Tamerton Poliot. T. R. A. B. 
v.c. 10. Isle of Wight ; Ninham Heath. A. G. More. v.c. 45.

coast between Dun heath and Berriedale. G. Lillie. v.c. 111.

A Supplement to F. Hamilton Davey's Flora of Cornwall. By 
Edgar Tiiurston, C.I.E., and Chambre C. Vigurs, B.A., 
M.D. Cantab. Reprinted from Journal of the Royal Institution 
of Cornwall, vol. xxi. 8vo, pp. xx, 172. Truro, Blackford, 1922

In this Supplement is brought together all that has been published 
and observed since the issue of the Flora in 1909—which was 
reviewed at some length in this Journal for that year—and bears 
testimony to the energy of the compilers and of those who have 
rendered it possible to produce so considerable a list. The actual 
additions, as tabulated in the introduction, include a species formerly 
recorded as doubtful and 28 unrecorded, with 142 “ varieties or 
forms” and 110 “aliens (species or varieties) ” mainly derived from 
the Reports of the Botanical Exchange Club, which devote much 
space to such records : many of the former, we think, are of doubt¬ 
ful value, and we fail to see what is gained by publishing casual 
occurrences on “fowl-runs” and “ballast-heaps.” It is interesting 
to note that Biot is, recorded in the Flora as extinct, still occurs in 
two localities. 
Turning over the extravagantly printed pages, one or two points 
suggests themselves for comment. The species of Fumaria —a genus
