REPORT FOR I903. 
33 
synonyms quoted by Ascherson and Graebner {Bro?nus caespitosus, 
Host, &c.), do not belong to this form, which perhaps would 
better be called forma leiostachya. — E. Hackel. 
Agropyron repetis x junceu?n. New Romney, Kent, growing 
with both the parents, and exhibiting a complete chain of inter- 
mediates ; the toughness of repens gradually disappearing as the 
plants became nearer to the jtmceian parent. These are selected so 
as to show a fairly intermediate plant, which is probably the A. 
acutujn of many English Botanists, if not indeed of the ‘ Flora 
of Kent,’ for which the hybrid is not given, although A. acutum 
is recorded from between Romney and Dymchurch, &c., July 1903. 
— G. Claridge Druce. Yes. — E. Hackel. All, or nearly all the 
records of A. acutum in ‘Topographical Botany’ require confirma- 
tion.— G. C. D. 
Lepturus. Rubbish heaps at Iver and West Drayton, 
Bucks, and Middlesex, July 1903. — G. Claridge Druce. The 
Lepturus from Bucks is a very intere'ting variety of L. fitiformis, 
Trin., which I should call var. pycnanthus^ differing from the 
type by the internodes of the rhachis being only half as long 
as the spikelet, whereas in the type they are almost of the same 
length as the spikelet. I do not believe it an abnormal or casual 
state of filiformis, but a true variety with a certain area of dis- 
tribution : it occurs in Egypt and Sicilia, and I only am astonished 
that it has never been distinguished from the type. In my last 
letter I have accepted Ascherson’s nomenclature of L. filifomnis (Z. 
incurvatus^ var. strictius, Buch.), but now I think it better to main- 
tain the name of Trinius. — E, Hackel. Z. filiformis, Trin., 
var pycnanthus, Hackel in lit. not previously recorded for Britain, is 
only casual in Bucks. — G. C. D. 
Asplenium septentrmiale, Hull. Near Keswick, Cumberland, 
August 1903. See ‘Journ. Bot.,’ p. 351 (1903). — G. Claridge 
Druce. 
Athyrium Filix foemina variety. Dry wood, S. Briavel’s, 
W. Glos., 21 Sept. 1903. This hardly answers to any of the 
named forms, the descriptions of which I have. — Augustin Ley. 
Are these fronds both from the same plant ? The smaller one 
is near A. Filix foe^nina, var. rhaeticum (Linn.). — E. G. Baker. 
Lastrea dilatata, PresL, var. alpma, Moore. West Wood, S. 
Briavel’s, W. Glos., Sept. 21, 1903. See Report (1902), p. 66.— 
Augustin Ley. Moore gives the following diagnosis for his var. 
alpina, the type of which came from Ben Lawers. ‘ Fronds narrow, 
linear-lanceolate, membranous, bi-sub tripinnate ; pinnae unequally 
deltoid; scales of the stipe broad-lanceolate, pale brown, variously 
two-coloured ; sori large, numerous, with small evanescent ragged 
membranous indusia.’ Mr. Ley’s specimens differ from above (a)
