240 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
14, July 1906. — r. Hilton. “ Misnamed on the labels P. pinna- 
tifida. See ‘ Journ. Bot.’ igo6, pp. 365, 428. An interesting ex- 
tension of this newly discovered species for Britain.” — W. R. L. 
Nepeta Glechoma, Benth., var. parviflora^ Benth. Stoughton 
Road, Leicester, i6th May 1906. — \V. Bell. N. hederacea^ Trev., 
var. parvijiora (Benth.). Is this more than a dimorphic condi- 
tion? — G. C. Druce. 
Leonurus Cardiaca, L. Waste ground on the Iffley Road, Ox- 
ford, Sept. 1906. Its first British record is that of Gerard’s ‘ Herbal,’ 
P- 5 ^ 9 ) 1597- ‘Ot ioieth among rubbish and other barren and 
rough places, especially about Oxford.” — G. Claridge Druce. 
LHtorella puncea, Berg., forma ? Llyn Helyg, Flintshire, 
Sept. 1906. — A. A. Dallman and J. A. Wheldon. We have had 
the following names suggested for this plant by various botanists, 
(i.) A sterile form of Isoetes. {2.) Subularia aqicatica (the smaller 
plants). (3.) Perhaps Lobelia Dortmanna. (4.) The submerged 
leaves of Alisma ; and (5) the name we suggest on the labels. 
When growing, the leaves are cylindrical, erect, and quill-like, not 
channelled, and in transverse section quite round, with from five to 
nine large lacunae arranged in a circle or nearly so. This does not 
agree with Isoetes. The plant seems too large for Subularia. We 
have not seen fresh Lobelia. The submerged leaves of Alisma are 
flattened and have a quite different appearance. 1 have it growing 
in my aquarium side by side with the present plarjt. Ordinary 
Littorella was growing and also flowering plentifully about the shore 
of the lake. The plants sent grew mingled with it, and there seemed 
nothing exactly intermediate. They also spread nearly all over the 
lake, carpeting the floor even in the middle, far from the shore, 
mixed with Isoetes. — J. A. Wheldon. “Rather strong, but I see 
nothing at all ‘ off type.’ ” — E. S. Marshall. “ Obviously Littorella. 
I have gathered the same thing in ponds in Derbyshire.” — W. R. L. 
Chenopodium opulifoliu 7 n x album ? Growing with a quantity 
of the two parents suggested, on waste ground by the canal near 
Aintree, S. Lancs. (59) Sept. 1901. It looked very intermediate 
when growing, the leaves recalling in shape the first named, but 
differing in being less glaucous and of a lighter shade of green. — J. 
A. Wheldon. “The fruit seems to be malformed or not formed, 
a further evidence of hybridity.” — W. R. L. 
C. opulifolium x ficifolmrti. A single plant growing with the 
two parents on the canal bank near Aintree, S. Lancs., Sept. 1901. 
'Fhe leaves showed a distinct tendency towards the shape of those of 
the first-named parent, although the habit of the plant as a whole 
more nearly approached that of C. ficijolium. — J. A. Wheldon.
