LASTREA FILIX-MAS. 



of Lasfrea filix-mas. In the Fernery of Mr. W. Winstanley, 

 at Chaigeley Manor, there are fine examples of both these 

 Ferns; the latter had fronds from six to seven feet in length, 

 lax; the former did not exceed four feet, and were compact, and 

 not so coarse in general appearance. Mr. Winstanley shewed 

 me both these forms growing in abundance on various portions 

 of his estate, through a range of several hundred feet of 

 elevation, the most luxuriant being in the woods along the 

 Kiver Hodder. 



Fig. 222.— Pinnae. 



Barnsii, Moore, {Carta, Wollaston.) (Fig. 222.)— A very 

 narrow variety, found in Lancashire by Mr. T. M. Barnes, 

 of Levens, near Milnthorpe, Lancashire. A narrow-fronded 

 variety, in which the pinna are brief, distant and subopposite 

 below, approximate and alternate above. Length of frond 

 fifteen inches; breadth almost equal, narrowing slightly towards 

 the base and towards the apex, and being only two inches 

 and a half wide in the widest part, that is, in the middle of 

 the frond. Pinnae brief, elongate-triangular, and one inch and 

 a quarter in length, and three quarters of an inch wide, about 

 fifteen pairs on each frond. Pinnules ovate-oblong, the basal 

 pair slightly stalked, the next two pairs widely attached to 

 the rachides, and the remainder attached throughout their 

 breadth, broad, leafy, touching each other, and bidentate on 

 the margin. Stipes and rachis rather scaly. The lower four 

 inches naked. Mr. Wollaston's name is very appropriate, yet 

 Mr. Moore's takes precedence, and, as named after the dis- 

 coverer, is equally appropriate. My thanks are due to Mr. 

 Thomas Moore, of the Chelsea Botanic Gardens, for fronds.
