LASTREA FILTX-MAS. 



Before describing tlie varieties of Lastrea filix-mas we men- 

 tioned that Mr. Wollaston had divided this Fern into three 

 species, and as we figured and described the varieties, reference 

 was made regarding the species to which they belonged. Mr. 

 Wollaston has bestowed great care and attention to this subject, 

 and his labours will be best understood by recapitulation, 

 especially as he informs me that I have made several errors 

 with regard to his new species; thus ahbreviata is Lastrea 

 propinqua and not Lastrea pseudo-mas; cristata-angustata and 

 Pinderi are, however, forms of Lastrea pseudo-mas instead of 

 Lastrea propinqua. The following arrangement will clear up 

 this difficulty.
