THE FERN FAMILIES OF BRITAIN. 
P. ang. pendens (drooping), Wills. !N'on-crested form, witli 
extremely large pinnules and drooping habit. 
P. ang. polydactylum (many-fingered), Wollaston; and 
vars. grande (large), Jones, and splendens (splendid). There 
have been several distinct finds of polydactylum, which is 
flatly crested, crests consisting of numerous points. The 
best are those named; all are good. 
P. ang. perserratum (prominently saw-edged), Patey. A 
very beautiful, non-crested form, with pinnules elongated and 
narrowly and sharply saw-toothed. 
P. ang, pulclierrinmni (very beautiful). Wills, Padley. 
Wild finds. Yery remarkable and beautiful sports, in which 
all the lower pinnules are very long and sickle-shaped, and 
the slender points of the ultimate divisions, in many cases, 
extend and expand into prothalli, from which plants can be 
raised by aposporous generation {vide Appendix). 
P, ang. pnlcherrimnm, Mrs. Thompson, Moly. Two 
other finds of same class, Mr. Moly’s the finest of all, 
bearing tiny crests at tips of pinnae. Apospory is not re- 
corded upon these, and we have not seen the plants; but in 
Col. Jones’ “Nature Prints,” lying before us as we write, we 
believe we detect its existence in both forms. 
P. ang. pulch. variegatum (variegated), Moly (7). One of 
Mr. Moly’s luckiest hits, which is saying much. This variety 
has all the charm described in connection with the last four 
forms, plus the uncommon feature of a distinct, yellow varie- 
gation, affecting the greater part of the fronds. 
P. ang. proliferum (proliferous), vars. Allchinii (All- 
chin’s), Cranfordianum (Cranford’s), densum (dense), Hen- 
leyse (Henley’s), Lyellii (Ly ell’s), and Wollastonii (Wol- 
laston’s). There are several forms so-called, all interesting, differ- 
ing generally from the normal in being much more finely cut 
and attenuated, and in bearing a profusion of young plants at 
the junctions of the pinnae with the main stalk. In a close 
atmosphere these develop several fronds while still attached, 
forming a dense, moss-like growth along the centre of the 
frond, and sometimes of the pinnae. Many of the other 
varieties present the same character in a less degree — some-
