delicate lace-like foliage of the submerged leaves. Mr. Fryer thinks 
that the suggested parentage cited above may be correct. It differs 
materially from forms of P. polygonifoliusP — G. C. D. Mr. Fryer 
now considers (‘Journ. of Bot.,’ 1899, p. 524) that P. Drucei is 
a distinct species, not a hybrid. — J. G. 
Potamogeton crisp us x perfoliatus, b. Cooperi^ Fryer. Abundant in 
the Loughborough Canal, August 1898. — A. B. Jackson. “ Mr. E. F. 
Cooper, the discoverer of this pondweed in Leicestershire, was kind 
enough to direct me to the Loughborough locality where it grows in 
masses at intervals along the canal. The plant usually produces 
flowers, but this year I was only able to find about one flowering 
specimen. Next year I hope to supplement these sheets by a series 
in the flowering state. See ‘Journ. of Bot.,’ Oct. 1891.”— A. B. J. 
Scirpus Holoschcenus, L. Shore of the Bristol Channel below Brean 
Down, North Somerset, i6th June 1898 and 30th September 1898. — 
J. W. White and E. S. Gregory. “The discovery of this rare sedge in 
N. Somerset by Mrs. Gregory is one of the most interesting botanical 
events of recent times (‘Journ. of Bot.,’xxxv., 125). A few specimens 
from the new locality will doubtless be acceptable.”- — J. W. W. 
Cnrex vulpina, L. , var. nemorosa (Rebent. Kiikenthal. Garden, 
Milford, 14th July 1898; orig. from ditch near Clymping, W. Sussex. — 
E. S. Marshall. “ Herr Kiikenthal remarks that this is a shade form. 
The original plants, however, grew in an open ditch near the sea, 
facing due south, and were taken for C. axillaris when first found, 
owing to the compound lower spikelets and elongated inflorescence ; 
they were then only in flower.” — E. S. M. “ This seems to be the 
true plant ; but the plant which has passed for it, i.e., that figured in 
‘ Boott’s Carices ’ from Battersea Fields, seems only a form with pro- 
duced bracts.” — Ar. Bennett.
