88 Notes on Lastrea remota (Moore). [Sess. 



quently the case with rigida ; and there is an absence of the 

 conspicuous glands with which the rachis scales, upper and 

 under sides of the lamina, and indusia are studded. 



" Lastrea remota is referred by some botanists to L. spinulosa, 

 but it differs in the far more numerous scales, many of them 

 narrowly lanceolate, by the greater number of pinnae in fronds 

 of equal size, by the veins being less impressed above, but 

 chiefly by the indusium being firm and very convex, and 

 retaining its shape like that of Filix-mas, instead of being 

 thin, flat, and soon crumpled up when the spore-cases swell 

 and raise its edges. There can be no doubt that it is a form 

 connecting L. spinulosa and L. Filix-mas." 



Dr Boswell Syme, from whom I have been quoting, says of 

 this plant : " I have seen no living specimens, nor do I possess 

 dried native specimens. I have received dried cultivated 

 specimens from Windermere, from Mr G. B. Woolaston, 

 through the kindness of Messrs Currie and C. E. Broome, 

 and also from Messrs E. Sang & Sons, Kirkcaldy, who had the 

 frond from Mr Lowe of Nottingham. The caudex and ver- 

 nation I am therefore unable to describe from personal ex- 

 perience, but Mr F. Clowes writes concerning the former, 

 ' A single crown of it, if let alone, will grow up like a tree- 

 fern, and requires support to prevent it being broken by the 

 wind.' In his paper in the second series of * The Phytologist,' 

 1860, p. 220, he says of the vernation: 'Forms side loops 

 like L. spinulosa; tip not so disengaged as to form the shep- 

 herd's crook ; ' and of the pinnae he says, ' Lower ones obliquely 

 triangular from the greater length of posterior basal pinnules, 

 the surface more or less twisted upwards.' Here we have 

 two additional differences from L. Filix-mas, in which the 

 well-known shepherd's crook formed by the top uncurling 

 frond is particularly observable, and forms a marked feature, 

 though it is said to be imperfectly formed in "oar. abbreviata, 

 while the second point is the twisting of the pinnae, as in 

 spinulosa and uliginosa, so that their plane does not coincide 

 with that of the frond as a whole, which it does in Filix-mas. 



" Milde says that the original discoverer of this plant, the 

 late Professor A. Braun, now (1867) considers this plant a form 

 of Filix-mas, but Milde himself inclines to the opinion that 

 it is a hybrid between Filix-mas and spinulosa; and Mr
