I D. mntriccefolium (Braun) with ovate bipinnatifid sterile fronds having distinct 
primary veins to the segments, and broadly spreading fertile fronds, is recorded 
from Stevenston, Ayrsh. (Dr O. St. Brody), by Mr Whitwell in ■/. c/ B. xxxvi. 
(1898) p. 291, t. 388 B, but some uncertainty attaching to the specimen, the record 
needs confirmation. Mr Whitwell follows Moore and Boswell in referring the 
Sands of Barry plant to B. la.nceolatum (Angst.) — H. & J. G.
