 As far as specimens are concerned I have had an ample supply at my com- 

 mand, in various states, of what I cannot but consider, after the most care- 

 ful investigation, as belonging to one and the same species. An opinion 

 has already been expressed in the ' Icones Filicum,' that the diflerences 

 between //. polyanthos and //. clavatum, Sw., were not permanent : and I 

 am confirmed in that opinion by further examination. The extreme states 

 of this species are indeed easily recognized and easily described ; but there 

 are various intermediate grades that baftle all attempts to discriminate them 

 specifically. The fronds are not only variable in general form and circum- 

 scription, but also in the direction of the primary divisions, sometimes 

 being curved downwards. As to size, the plant varies from 1 — 10 or 12 

 inches in length. Small specimens of /3., when a little crisped, as they some- 

 times are, approach the II. undulation, Sw.
