of the Botanical Exchange Club for 1S63. In this Mr. Baker agrees 
with Mr. G. E. Hunt in thinking that it should be considered a form 
of C. ampullacea , and not of C. vesicaria as Mr. Babington considers 
it. It differs from C. ampullacea in its smaller size and more slender 
habit, and more conspicuously in its spikes tapering towards each end 
and not at all squarrose, the perigynia being ascending and not spread- 
ing ; they also taper gradually, and not abruptly, into the beak. 
From C. vesicaria it differs in its more slender habit, obtusely tri- 
gonous and smooth-angled stem, channelled and glaucous leaves, and 
female spikes with more numerous and smaller perigynia ; also in its 
roundish-obovate, trigonous nut, which is precisely similar to that of 
C. ampullacea. 
It cannot be considered as a hybrid between these two species, as 
the nuts are perfectly developed, and Mr. J. Sidebotham, who was 
kind enough to send me specimens with mature fruit, informs me that 
neither C. ampullacea nor C. vesicaria grow in the neighbourhood of 
the locality of C. involuta ; indeed, he says, “ I do not know of either 
within a mile or two.” 
Leersia oryzoides, Sw. “ Bv the canal, near Woking Station, Surrey. 
It occurs sparingly by the canal side, almost opposite to the railway 
station ; more plentifully about the first brick-bridge (not the wooden 
foot-bridge) beyond the station in the ascending line of the canal, 
where it is crossed by the road to Horsell. A new locality, not re- 
corded in the ‘Flora of Surrey.’ ” — H. C. Watson. 
Alopecurus fulvus, Sm. “ About a pond between the church and 
school-house, in East Moulsey, Surrey ; a locality not given in the 
Flora of the county.” — H. C. Watson. 
Pheyopteris pluniosa, J. Smith. Mr. Baker sends from Kew Gardens 
a number of specimens from the plant thus named by J. Smith. “ It 
is a very delicate, elegant, finely-cut form of Athyrium Filix-fcemina, 
with the sori much reduced in size and the involucre generally, but not 
invariably quite abortive. The original plant was found in Yorkshire, 
and propagated and circulated in gardens by Messrs. A. Stansfield and 
Son, of Todmorden.” — J. G. Baker. 
Pilularia ylobulifera, Linn. “In a water-splash, on Ditton Marsh, 
where the main line of the London and South-Western Railway crosses 
the highway, called the ‘Portsmouth Road,’ profusely there in 1868, 
after entire evaporation of the water.” — H. C. Watson.
