598 87, FILICES. 
near Greenwich or near Gravesend ? — (Elymus crinitus, an intro- 
duced casual, is enumerated in the Appendix to the Flora of 
Surrey.) 
Lepturus incurvatus, Trin. 
Province - 15. Fife, on ballast. Doubtful elsewhere. 
Casual? Cyb. iii. 246. L. filiformis is the usual form or species 
in Britain, and has been frequently recorded under the name of 
incurvatus. Iam not prepared either to assert or deny that true 
or typical incurvatus has occurred in this country except as a 
casual introduction on ballast heaps, etc. 
Eleusine. Chloris. Lappago. Atgilops. Crypsis. 
Casuals. In the Exchange Club Report for 1858 we are told that 
Eleusine indica was found by Dr. Carrington, near Bury in 
Lancashire. And in the same report Mess. Hobkirk and Ingle 
are stated to have found the Chloris compressa and Lappago 
racemosa, with other exotics, near Huddersfield in Yorkshire. 
4igilops ovata and Crypsis aculeata are enumerated among the 
various other introduced casuals, in the Appendix to the Flora of 
Surrey. It seems little worth while more formally to notice these 
rarely seen grasses. 
87. Finices. 
Gymnogramme leptophylla, Desv. 
Province - 15. Aberdeen; Miss Veitch, fide W. Tanner. 
Error. Cyb. iii. 870. Phytologist iv. 600 & 716. 
Polypodium (vulgare) cambricum, Linn. 
Province - 6. Glamorgan; Ray’s Synopsis. 
Syn. 1874. As being a monstrosity, rather than a variety, this 
should scarcely be admitted here, except on the ground that it is 
so usually noticed in a special manner in fern-books, and has 
formerly passed for a species of itself. Polypodium vulgare is 
found with the pinne ranging from quite entire to coarsely 
serrated or even deeply incised ; the cambricum form is a further 
grade of marginal indentation, with the pinne irregularly or 
laciniately pinnatifid. It is now a plant cultivated in Ferneries, 
but Iam not aware of any certain locality for it wild in England. 
Mr. Newman states that he has received it from Ireland. 
Cystopteris (fragilis) dentata, Hook. 
Provinces 1---5 67891011 12--15 16. As reported. 
Syn. 1379. I do not pretend to distinguish this fern clearly from 
fragilis ; nor can their localities be satisfactorily apportioned 
between them. C. angustata is even more unsatisfactory. And 
C. regia seems to be truly but another name for the present 
segregate ; except in so far as it may have been applied to the 
alien C. alpina.
