CAREX ERICETORUM, AND PSAMMA BALTICA. IN ENGLAND. 23 
"heaths would suit C. pilulifera ; but the date is too early for 
this plant, C. praecox , or, not improbably, C. ericetorum may 
have been the plant intended.” I have little doubt it was 
ericetorum, as specimens of this would not be unlike small 
ones of montana, so that Sir J. Cullum would be the first 
observer of the plant. In cultivation in my garden, 
C. ericetorum and C. Montana commence to flower early 
in April. 
Because Mildenhall heath was sand, Prof. Babington 
formerly supposed that the Trevelyan specimens were mis- 
located, and had come from Cambridge ; but as Syme pointed 
out in Eng. Botany, the species is chiefly found on sandy 
soil on the continent. 
In Finland ericetorum is abundant, occurring in eighteen 
botanical provinces up to 68° 25' N. Lat., while C. caryophyllea, 
Latour (C. praecox, Jacq.) is found only in two provinces ; the 
reverse holds good in England. 
When in flower it is easily distinguished from C. praecox by 
the glumes of the female spikes being bordered by a silvery- 
white band, and ciliated. I expect it will be found in some 
of the heaths of the Breckland district in Norfolk if looked 
for sufficiently early ; i.e., from the end of April to middle of 
May, according as the season is late or early. 
C. montana was first found by Mr. Mitten in May, 1843, 
near Tunbridge Wells, quite accidentally, as he told me ; he 
having jumped over a gate to look at some other plant in 
a heathy field towards Eridge.

Chalk bank on Risby heath, 1877, A. Bennett. On May 8th, 
1896, Mr. W. West, Junr., saw nearly 40 stems of it, many 
fruiting, near the east end of the bank.
