POI.YSTICllUM ANfJULAKE. 187 



unequal in length. Unlike the ordinary form of Grandidens, the pinnae 

 are not abrupt, Ijut gradually taper to their apices; and this is also the 

 case with the apex of the frond, giving the frond quite an Athyrium 

 look. I am indebted to Mr. R. J. Gray for fronds. — Since writing the 

 account of this Fern I have received several forms of it from the Rev. 

 Charles Padley, of Bulwell Hall. Four plants, differing very much from 

 each other, were found l>y Mrs. Thompson, of South Lawn, Exeter, at 

 Clist Hydon, and these are the varieties forwarded by Mr. Padley. One 

 of the varieties, which has been provisionally called Grand Ulens-aiigti^- 

 tiitirm, differs in l>eing narrower, the pinnules smaller, the upf>er third 

 of the pinnas confluent. Length twelve inches, width scarcely three 

 quarters of an inch near the base, and only two inches in the widest 

 ]mrt. Basal pinnae consisting of a pair of stalked, diminutive, cup-shaped 

 pinnules; the rest of the pinnae undivided; being simply toothed on the 

 edges; apex rounded. The next few pinuje have two or three pairs of 

 stalked rather larger pinnules and an undivided upper portion. The 

 largest pinnae have five or six pairs of stalked pinnules and a long 

 undivided ajiex, conspicuously toothed, mostly bidentate. Pinnules 

 cuneate at the base, from rotund to ovate, occasionally linear or depau- 

 I)erate. Pinnae approximate and ascending. Pinnules approximate. The 

 frond not narrowing to the a|x»x, ending abruptly in a similar pinna to 

 those on either side the rachis, and equally developed, with equal-sized 

 ])innules. Sori confined to the apex of the frond, situated on the edge 

 of the pinnules, almost suprasoriferous. — The second variety combines 

 the characters of Graiididens and Aagnstifrons: it is eighteen inches in 

 length, and two inches and a half wide, and partakes more of the 

 characters of the latter variety. — ^The third variety is more lax, more 

 slender, has a less number of pinnules, and, though partaking of the 

 characters of both Grandidens and Angustifrons, partakes more of the 

 chai-acters of the former variety. — The fourth variety is very singular, 

 and might appropriately be called Grandldens-coiinv.tum. It is only six 

 inches in length, the stipes occupying two inches; width very various, 

 from less than an inch to three inches and a half Pinnae two inches 

 in length, being indiscriminately dispersed amongst others from under 

 half an inch to an inch long. Pinnae alternate and approximate, the 

 smaller pinnae consisting of from one to four pinnides, and in place of 

 an ultimate pinnule a cornute termination, the largest pinnae consisting 

 of from six to eight pairs of stalked pinnules and a long undivided apex. 

 Pinnules very various both in size and form, no two alike. A very 

 slender and singular Fern.
