Wolley-Dod. Not typical majus, which should have shorter 
peduncles, but best under that by its large heads, &c.—C. E. 
‘Satmon. Also sent by Major Wolley-Dod, who remarks: “ By 
the size of its leaflets and flower-heads, as well as by its suberect 
habit, this should go to var. majus, but that is said to have shorter 
peduncles. Var. minus is a much smaller plant in all respects, 
but no hard-and-fast line can be drawn between them.”—Type. 
Var. majus (not always a large plant) has golden-yellow flowers, 
as in 1’. agrarium; in this plant they are pale yellow.—E. 8. 
MARSHALL. 
Poplar. This can : 
(Black Italian Poplar), by its rough burred trunk, denser foliage, 
and the leaves having a cuneate and not truncate base. I have 
sin 
characteristic bole. P. monilifera, another name for which is 
tent to take the Prodromus as a guide.—E. F. TON. From the 
mention of a “very tall tree,” I think that’ this is more likely to 
be P. canadensis.—E. 
AVENA PRATENSIS Linn. var. LONGIFOLIA (Parn.), or near it. 
Limestone bank in Cressbrook Dale, Derbyshire, v.-c. 57, J uly 24, 
1907.—A. B. Jackson and T. E. Routu. Not so pronounced as 
Mr. Jackson’s specimens distributed last year from Notts, though 
doubtless approaching “longifolia.” I do not think this variety 
is recognized on the Continent, and has it anything beyond the 
longer leaves to separate it from type? If not, I cannot see muc 
in it—C. E. Satmon. This may perhaps be placed under the 
variety, but all my specimens of ongifolia (Parn.) have longer 
leaves than these; on one of them Hackel remarked “a very slight 
which still more applies to the sheet submitted to me.— 
INTON.
