Notes on two forms of hybrid Woisie.… Es 
TC by WE. Nicnoïson | 
Early in the year r 1904 I received from M H. N. Dixon: æ 
immature capsules of a Weisia, which he suspected of being a 
hybrid between W. crispa, Mill. à and W. crispata Ldb. & and 
which he in company with Miss Lister had gathered on the 
chalk cliffs at Pinhay near Lyme Regis in Dorsetshire. He further 
mentioned that Mr John Marten of Bredhurst, Kent, had sent him 
some capsules of the same form and of a form which he believed 
be a hybrid between W. crispata © X W. crispa © from Boxley 
f rren near Maidstone. Mr Marten was also good enough to 
send me small pieces of the same forms. I could see no reason to 
ispule accuracy of these determinations, but since the capsules 
ere immature and the material insufficient for an exhaustive 
mination, it seemed rash to pronounce too definitely in favour 
their hybrid origin. As; however, the alleged parents we 
oth common on the cha downs round Lewes, L instituted
