InterruPTUM, Wollaston. (Figs. 360 and 361.) — Found at 

 Ambleside, Westmorland, by Mr. G. B. Wollaston, of Chisel- 

 hurst, and independently raised from spores by Mr. J. Young, 

 of Taunton. A singular variety, with shortened pinnae. The 

 fronds somewhat dvv^arf, and occasionally branched near their 

 apices, and becoming bifurcate and even trifurcate. The pinnae 

 differ considerably both in their length, form, and mode of 

 division, their apices usually simply or multifidly divided, and 

 so become ramose. The pinnules also differ much in size, and 

 in the number and shape of the lobes, which are also variously 

 toothed, the serratures frequently acute and profound.
