ASPIDIUM CRTSTATUM. 61 



Length of frond from one to three feet; colour heavy green. 



Lastrea uliginosa of Newman, will, in all probability, be 

 raised to the rank of a species when better known. It bears 

 its fertile fronds long before A. cristatum; the latter arc ripe 

 about the last week in July, whilst A. uliginosum becomes 

 ripe in June. The fronds have more the character of A. spin- 

 ulosum than of A. cristatum; they grow upright, and are 

 naked for nearly half their length, the pinnules are smaller 

 and more numerous, and the fructification extends over the 

 whole under side of the frond. Through the kindness of Mr. 

 Henry Sherbrook, of Oxton, I have been enabled to examine the 

 plants in their native habitat of Nottinghamshire, namely, Oxton 

 Bogs, and also to bring away with me a series of plants of 

 both forms, and although both flourish best in a moist situ- 

 ation in peaty soil, still A. uliginosum will grow in a much 

 drier situation than A. cristatum, and is an easier plant to 

 grow under pot-culture. 



For plants of a variety of this Fern from North America, 

 known as the Lastrea cristata-major , I am indebted to Mr. 

 R. Sim, of Foot's Cray. 



It is in the Fern Catalogues of Messrs. Young, of Taunton ; 

 Bass and Brown, of Sudbury; A. Henderson, of Pine-apple 

 Place; E. G. Henderson, of St. John's Wood; Stansfield and 

 Son, of Todmorden; Cooling, of Derby; Pearson, of Chilwell; 

 Kennedy, of Covent Garden; Cutbush, of Highgate; Sim, of 

 Foot's Cray; Rollisson, of Tooting; and Veitch, Jun., of 

 Chelsea. 



The illustration is from a plant in my own collection.
