acutum DC. in the narrowest sense. Ascherson and Graebner 
give T. pungens Pers. = A. pungens R. and S. as T . repens x 
junceum and T. acutum DC. under this. Babington made the 
last named a distinct species. — W. O. Howarth. 
Agropyron pungens R. and S. var. aristatum Hackel. ( Triticum 
Pungens Pers. var. aristatum Warren. T. littorale Host. p.p.). 
Bank of the tidal Avon below Bristol, W. Glos., July, 1928. — 
Jas. W. White. A. pungens R. and S. var. aristatum Hackel. 
A comparison between this form and the above shows the 
great variability existing, which is not to be wondered at. 
Ascherson and Graebner remark on this : “ We find forms 
with narrow and broad leaves, others with vigorous or scarcely 
vigorous culms, with large or small spikelets, etc." — W. 0. 
Howarth. 
Blechnum Spicant With. var. ramosum Kim. Glencar 
Waterfall, Co. Leitrim, Sept. 4, 1928. — I. M. Roper. In my 
specimen of this gathering the “ throw-back ” to dichotomy 
is not so perfect as in the P. S colop endrium. The two 
gatherings form a useful skeleton “ series ". — J. E. Lousley. 
Phyllitis S colop endrium Newm. var. ramuscula Lowe. 
Blaise Castle Woods, Bristol, W. Glos., Nov. 22, 1927. — Ida 
M. Roper. This is one of Moore’s Series multifidum of varieties 
of which Series alone there are about 40 named forms. The 
aggregate variety is Scolopendrium vulgar e wax .multifidum Gray, 
and is on record from Frenchay, near Bristol, where it was 
collected by T. H. Thomas and is figured in a somewhat more ' 
multifid form in Moore’s Nature Printed British Ferns. A 
fern fancier might give a closer varietal name than the aggre- 
gate. Moore does not mention var. ramuscula Lowe. — A. H. 
Wolley-Dod. A most interesting plant. The apex exhibits 
excellent examples of dichotomy — a primitive character 
which is usually masked in Ferns by one of the branches 
becoming stronger than the other. Bower, in The Ferns, 
Vol. I, 1923, p. 332, endorses the idea that such aberrations 
should properly rank as “ individual sports ”, and also gives 
other valuable notes on “ crested varieties ”. As Lowe 
recognised over 400 " varieties ” of this one species, almost 
all of which are undistinguished sports and reversions, the 
futility of keeping up such varietal names is obvious. — J. E. 
Lousley.
