REVIEWS, BOOK NOTICES, ETC. 53 
British plants may be divided into three groups by the number of 
the leaf-tips: (1) very numerous vulgaris and major; (2) 7-15 
intermedia and ochroleuca ; (3) 14-20 minor and Bremit. 
*‘Since writing this account of the Utricularias, Dr. Gluck . . . 
emphasises the impossibility of distinguishing sterile conditions of 
U. Bremii and U. minor; hence the British records of the former 
based on barren plants appear to be conjectural.” 
In the second part of the Report by Dr. Moss, there are as usual 
many interesting notes by most of our best-known botanists. The 
following are a few :— 
** Viola saxatilis, Schmidt.—Roadside bank, S. of Loch Rannoch, 
Perthshire (88), July t910.—A. Wilson and J. A. Wheldon. 
** Sagina subulata, Presl.—Sandy roadside, Brown Point, Arran; 
¥.e.) 100, n.c.r, July rgi0.. V..S. Travis. 
“Tilia |? platyphyllos, Scop. |.—Naturalwood near Llanvair Discoed, 
Mon.; v.c. 35, 23rd June 1910. W. A. Shoolbred. The specimens 
are not typical, and are perhaps from shoots of suckers or of 
adventitious buds low down on the stems ; and neither flowers nor 
fruit are sent. However, all the material belongs to the small-leaved 
lime, Z. cordata (T. parvifolia, Ehrh.; 7. ulmifolia, Scop.), and not 
to the large-leaved lime (Z. flatyphylla), nor to the common lime 
(Z. europea). It is not, I think, usually stated in the floras that the 
leaves of Z. cordata, which are borne on suckers, etc., are relatively 
large (sometimes very large) and have relatively short petioles. 
T. platyphylla may always be distinguished by its hairy twigs, and 
T. cordata by its normal leaves having very long petioles. The 
cymes of Z. cordata are not pendent like those of the two other 
limes; and they flower later than those of 7: europea and 
T. platyphylla. Last year, for example, near Cambridge the flowers 
of Z. cordata opened on July 16th, those of Z. europea on June 
28th, on which latter date those of 7: platyphyl/a were already fully 
out ; and the flowers of Z. europea and of 7. platyphylla were over 
when those of Z: corda‘a appeared. It would be interesting to 
ascertain whether or not this is invariably the case, as some 
Continental floras give Z. europea as a hybrid of Z. cordata and 
T. platyphylla. T. cordata is also later in coming into leaf than its 
two allies. CC. E. Moss. 
“ Juncus tenuis, Willd. [ref. No. 84].—Roadside in Glen Ogle v.c. 88, 
September roth, r911.—M ‘Taggart Cowan, jun. Yes, our member 
Mr. P. Ewing has also sent it me from Ayrshire this year, a N.C.R. 
for 75. G. Claridge Druce. 
Haddington, v.c. 82... 
Yes, apparently new to Haddington, v.c. 82.—C. E. Salmon. 
Correct.—P. Graebner. 
* Agrostis alba, L., var.—Sandy shores, Kildonan, Arran, v.c. 100, 
July t910.—W. G. Travis. . . . A. alba, var. condensata, Hackel, 
med., var. coarctafa auct. plur. non A. coarctata, Erh.—E. Hackel.” 
Altogether the Report is a most valuable one, and should be very 
helpful to all those studying the British flora.
