54 Petty : Some Plants of Silverdale, West Lancashire. 



Athyrium Filix-foemina Roth. Waterslack Wood, but not 

 common in the district ; probably rooted up. 



Scolopendrium vulgare Sym. 1864. Bot. Chron., 75. Fre- 

 quent, C. J. Ashfield. Mr. Wilson says the same, and so 

 I found it, but no varieties. 



Ceterach officinarum W 7 illd. 1859. Moore and Bradbury, 

 Nat. Print. Ferns, 8vo. ed., ii., 204. Silverdale, S. Simpson. 

 According- to the late Anthony Mason, in Aspland's Guide 

 (1869), it was at one time obtainable at Silverdale. More 

 recently it grew in some quantity in a certain place in which 

 I sought for it in vain, but ultimately I found three plants, 

 all very small, on the opposite side of the village. 



Cystopteris fragilis Bernh. This also, I am told, was once 

 much more common than now. It is recorded 1859. Moore 

 and Bradbury, ii., 259, from Silverdale, but no finder named, 

 and on p. 265 the variety dentaia Hooker. I have seen no 

 Silverdale specimen, but have from Yealand Redmayn, and 

 g-athered it myself in Warton. 



Lastrsea Filix-mas Presl. In the woods and hedge-bank-. 

 No varieties seen. 



Lastrsea rigida Presl. 1843. Phytologist, 478. Sparingly on 

 the confines of the count}', adjoining Westmorland, S. Simp- 

 son. 1859. Moore and Bradbury, Nat. Print. Ferns, 8vo. 

 ed., i., 207, Silverdale, and often repeated. Mr. Albert 

 Wilson found it near Silverdale some time ago. I have seen 

 it in his locality. 



Lastrasa spinulosa Presl. What I took to be this in the hedge 

 at Little Hawes Water, but none was gathered, and the 

 locality has not been visited since 1898. 



Polypodium vulgare L. On walls, trees, and hedge-banks. 

 I have seen the varieties bifidum and denticulatum. 



Equisetnm arvense L. From just above shore level to well up 

 on tram-road at Trowbarrow. 



Selaginella selaginoides Gray. 1883. Rep. Bot. Rec. Club, 

 1 881 -2, p. 249. Haw 7 es Water, A. Wilson. 



Chara fragilis Desv. Wood Well, 1898, iyoo-1901, but, 

 visiting - the locality in August 1901, I found the well had 

 been cleaned out on account of the drought, so that for the 

 present the plant is in abeyance ; this applies also to 

 Zannichellia palustris L.
