390 FILICES. 



SCOLOPENDRITJM, Siv. 



855. S. vulgare, Sym. Harfs-twigue. 



Native ; in damp woods, on shady hedge-banks, and in the 



crevices of rocks. Very common. June to August, or later. 



Area general. 



One of the commonest of the ferns. Very variable. Plants with all 



or some of the fronds bifid or multifid are often foimd. This species 



occurs on the damp Avail of a storehouse in Vauxhall Street, Plymouth ; 



several plants there, 1880. 



CYSTOPTERIS, Beryih. 



856. C. frag-ilis, Bernh. Brittle Bladder Fern. 



Native ; on walls. Very rare. June to September. 

 D. V. Four plants or patches, one on an exposed wall, the rest on a 

 neighbouring shaded one, in the parish of Corn wood, 1865 ; 

 still at the latter spot, 1874 ; ten plants seen there, 1879. 

 I cannot be held responsible for the opinions attributed to me in Flora 

 of Devon and Cornwall concerning two ferns, said to be fragilis, 

 collected by Mr. Holmes at Woodside and Bickleigh. I remember the 

 fact of Mr. Holmes showing them to me many years ago. 



ASPIDIITM, Siv. 



857. A. aculeatum, Sio., mclusive of var. h. lohatum. Common 



Prickly Shield-Fern. 

 Native ; on hedge-banks and other bushy places. Rather rare, 

 and sparsely, though widely, distributed. Part of June to 

 September. 



c. II. Between Maker Church and Millbrook ; near Cawsand ; Keys, 

 Fl. iii. 293. Lane near Moditonham, very sparingly. Que 

 plant on a hedge-bank at Calstock, 1879. On a dry exposed 

 hedge-bank near St. Dominick ; also seen many years ago in a 

 small wood there. 



D. III. Sparingly on exposed hedge-banks near Roborough. 



IV. Efford Lane and Widey, near Plymouth ; Keys, Fl. iii. 293 : a 

 single small plant near the latter place, 1877. Sparingly on 

 some hedge-banks in Egg Buckland parish ; a specimen col- 

 lected not far from the village considered by Baker "good 

 aculeatum.'" Near Plympton, on hedge-banks. 

 V. Between Puslinch and Lolesbury. Between Ridgway and Ivy- 

 bridge. Two or three plants near Mount Pleasant, 1879. 

 VI. Ivybridge ; Mrs. Applehee ; near Ermmg-ton, 1852; Banker, 

 Keys, Fl. iii. 293 : many plants seen m the latter neighbourhood, 

 1878 ; placed by Keys under var. lohatum, but if obliged to 

 divide this from the type, I would rather call them aculeatum 

 genuinum. Lane between Sequers Bridge and Kingston.
