Brachypodium pinnatum Beauv. Radwell, Herts., v.c. 20., 
Aug. 4, 1921. — J. E. Little. This is Coleman’s record (of 
? 1 843). “On a ditch bank at Radwell, near the river Ivel.” 
With the form now sent, which has sometimes slightly pubescent 
glumes, though probably not sufficiently so for var. pubescens 
Gray, was growing also a more robust form (forma corniculatci 
Hackel) of which I send two sheets for confirmation, and shall 
hope to obtain more another year. The leaves in the latter are 
broader, the culms stouter, and the spikelets longer and larger, as 
well as curved. — J. E. Little. A mixture — see notes with each 
specimen. — C.E.S. 
Bromus madritensis L. On limestone rubble by the river 
Avon, below Bristol, v.c. 34, June 12, 1921. — H. S. Thompson. 
The reason why Wm. Curtis gave the name diandrus to this plant 
is explained thus in his “Flora Lond.” with its excellent plate : — 
“If our plant” (which he observed at Bristol in 1793, “ at the foot 
of St. Vincent’s Rock ”) “be the Bromus madritensis of Linnaeus, 
which we are induced to believe from its according so well with 
the figure of Barrelier, to which he refers, it will be found to be 
a native of Spain and Italy and perhaps other parts of Europe. 
There can be little doubt of its being the muralis of Hudson, 
though he has omitted to notice the peculiar circumstance of its 
having only two stamens, a phenomenon so unusual in plants of 
this tribe, that we have thought it ought to receive its trivial 
name from it, more especially as the plant is found to be confined 
to no particular country or situation.” His abbreviated descrip- 
tion runs : Bromus diandrus panicula erecto-patente, spiculis 
multifloris, flosculis diandris. In the beautifully printed 
“ Agrostographia ” of Scheuchzer (Zurich, 1719) the plate of 
Barrelieri {Icon. 76 I) is described as “optime hoc gramen 
reprsesentat,” and Scheuchzer’s long Latin diagnosis is wonder- 
fully accurate. — H.S.T. 
Lastrea spimdosa Presl. 1 var. exaltata (Lasch.) Syme. Oughton 
Head, Hitchin, Herts., v.c. 20, June 30, July 15, 1921. — J. E. 
Little. Not recorded for the Ivel basin in Pryor’s “Flora of 
Herts.” These examples appear to correspond to Miss Roper’s 
plant from Shapwick, W.B.E.C. Rep., 1918, p. 127. — J. E. Little. 
True, this resembles Miss Roper’s Shapwick plant of 1918, which 
Mr. Salmon said, “if not type, might come under exaltata Lasch.” 
rather than elevata ; but it is almost impossible to name the 
forms of L. dilatata and spinulosa. T. Moore in 1863 remarked 
upon the various transition forms, and in his “ Nature Printed 
British Ferns,” Vol. I, the admirable plate of what he then called
