COMPOSITE. 119 
In tlio three Scottish localities mentioned it is tlie sub-male 
plant which occurs. It is included in this work not because it is 
perfectly naturalized, but because it may be confounded with P. vul- 
garis — my specimens from Etubislaw are so named.

Leaves roundish, deeply cordate with the lobes not conti- 
guous, dentate and denticulate, at first arachnoid - floccose, at 
length glabrous above and grey -cottony beneath. Sub -male 
florets in a short conical - oblong racemose panicle or raceme, 
scarcely elongating after flowering ; the female in a longer and 
more lax racemose panicle or raceme, which becomes lax and 
much elongated after flowering. Phyllaries rather obtuse. Female 
florets filiform, obliquely truncate. Branches of the stigma in the 
sub-male florets very short, ovoid-obtuse. 
In wet places, especially by the sides of streams. Not un- 
common in England and the South of Scotland ; rare north of 
the Forth and Clyde. The female plant rare. 
England, Scotland, Ireland. Perennial. Spring. 
Rootstock creeping, fleshy. Leaves, when full-grown, very large, 
on stout hollow channelled petioles ; lamina sometimes 3 feet in 
diameter, deeply cordate at the base, scolloped at the edges, with 
the portions between the projections finely toothed : the leaves at 
first are arachnoid above and densely so beneath, but when mature 
must of the covering disappears, though they still remain grey and 
more or less arachnoid beneath. Scapes produced before the leaves, 
or as the latter are beginning to appear, 4 inches to 1 foot high, with 
pale-greenish lanceolate empty bracts, which have sometimes a small 
lamina at the apex ; upper bracts strapshaped or linear-acute. An- 
t hoiles very numerous. Pedicels in the sub-male plant very short, 
simple, or sometimes 2- or 3-flowered, — longer and more slender in
