nist, who may visit Lewes, for fresh or dried specimens of it. Mr. 
AVarren was kind enough to give me some ripe seeds, which, however, 
have not germinated. I have some fears that they may never do so, 
as I sowed five or six years ago Continental seeds which failed to 
grow, though those of R. Hippolapathum , Fries. ( aquations , ‘ L.,’ 
Koch, &c.) gathered at the same time and treated in the same way 
produced a number of plants. M. Crepin, in his note3 ‘ Quelques 
Plantes rares ou critiques de la Belgique,’ fasc. v., p. 78, endeavours 
to show that R. maximus tends much more to R. aquations (i.e., Hip- 
polapathum ) than to R. Hydrolapathum. This is certainly not the 
case with the British R. maximus .” — J. T. Boswell.

high and almost inaccessible cliffs near this (Seggiaden, ^between 
Balthayock and Glencorse), at a point far from any garden or 
houses, and it had all the appearance of being perfectly wild, seeding 
freely under old blackthorn bushes on a warm southern aspect.” — H. 
M. D. Hay, 1872. 
Ceratophyllum denier sum. “ Pond on Weston Green, Thames 
Ditton, Surrey.” — H. C. Watson. “ In a letter Mr. Watson mentions 
that the spines at the base of the fruit elongate as the fruit grows, but 
are scarcely perceptible at first.” — J. T. Boswell.

Typha angustifolia, L. “A young specimen from the river bank of 
the Tavy at Lapwell, with three foliaceous bracts, one older speci- 
men with the bracts gone. I suspect that the male spikes of this will 
be found to be always furnished with foliaceous bracts, but that their
