plished botanist. In the letter, written in 1726, he mentions, in 
addition to many other interesting records, that he had gathered

side of ye wild Brooks near Amber rly, Sussex.” The specimen of 
S. palustris representing this number in the Dillenian herbarium is 
unfortunately unlocalized, so that we have no confirmatory evidence

eles SILVESTRE IN Rapnorsuire.—In September, 1900, I had 
an hour or two on the Stanner Rocks, Radnorshire, and pic cked up 
one or two specimens of a crucifer which I did not recognize, but 
which the Rey. E. F. Linton has kindly named a his It is 
Thlaspi alpestre var. silvestre (Jord.). There ery small 
quantity of it, and I could not see any (though ve sie ‘admit that 
my search was cursory) in July of this year, when I revisited the 
spot. If itis native, and a eer, ee more than a chance bird-sown 
individual, how can it have been passed over by the ard bee 
who know the Stanner Rocks? It t occurs, according to yn, 
about Pontneddfechan and and probably in Joh Vale of Neath eh 
of the Stanner Rocks makes si ont more probable. There is a 
great likelihood that search will reveal it in other parts of these 
S. Wales counties. Mr. Arthur hemnitt informs me that the plant 
of Caernarvon and Denbigh is 7’. occitanum, T. silvestre being known 
only from Durham, Northumberland, Forfar, and West Perth. —
