THE FERIf FAMILIES OF BRITAIN. 
distinct finds of similar pattern, but hardly in so exaggerated 
a form. 
P. ang. cristatum, Wollaston (9). A beautifully tasselled 
form ; small crests at pinnae tips, but heavy and finely-divided 
one at frond tip. 
P. ang. cristato-gracile (crested, slender), Gray. A some- 
what slender- growing form, with frond tips and pinnae neatly 
tasselled. 
P. ang. congestum (crowded). A very beautifully con- 
gested form; pinnae and pinnules closely set and overlapping. 
P. aug. crispato-foliosum (crisped, leafy). A very distinct 
and leafier form, with same overlapping character as last. 
P. ang. capitatum (headed). Miles. Peculiarly distinct; 
pinnae neatly crested, and frond with remarkably broad, flat, 
spreading crest. 
P. ang. cruciatum (crossed), Elworthy. A narrow-fronded 
form, with double pinnae, starting at about right angles to 
each other, forming so many crosses with the opposite pairs — 
hence the name. 
P. ang. divisilobum robustum (divided-lobed, robust), 
Moly. This belongs to a section of the family in which the 
pinnules or lobes are again divided, the fronds being really 
tripinnate, with a peculiarly dense and rich appearance, owing 
to this extra development. When fully developed, this variety 
is even again divided, the ultimate divisions being further- 
more saw-toothed. Fronds dense, and occasionally proliferous 
on the stalks. 
P. ang. div. laxum (loose). Wills. A distinct form, thrice 
divided, but not so dense, and with somewhat drooping pinnae. 
Yery beautiful. 
P. ang. div. cristatum (crested), Ivery (6). A real gem, 
and, being proliferous, easily obtainable ; the pinnae have splendid, 
spreading, uniform crests, over 2in. wide, and the frond tip 
a very neat one to match. Well grown, it has no equal in 
its way. 
P. ang. div. plumosnm densum (densely feathery), Jones. 
This Fern is apparently the ne plus ultra of division and 
delicacy. It has been called the Todea superha of the British
