182 THE BRITISH FERNS. 
obtained a fine form of this character from Whitbarrow, West- 
moreland. This variety is sometimes called crispum multifidam in 
gardens. 
102. undulato-projectum (M.). This is à curious and constant 
broad somewhat undulated form, with a cordate base, remark- 
able for the production of distant projecting pointed marginal lobes; 
half an inch long or more, and sometimes split into three or four 
linear tooth-like divisions.. It was found at Mulgrave Castle, York- 
shire, by Messrs. Stansfield, of Todmorden. 
103. corrugatum (Woll.). A very pretty variety, with fronds a 
foot or more in length, and two inches broad; they are cordate at 
the base, attenuate at the apex, and elegantly undulated or corru- 
gate on the margin, where they are also somewhat sinuately or. 
sometimes towards the top lacerately-lobate. It is a fertile form, 
found near the Devil's Punch Bowl, Hindhead, Surrey, by de 
man, a collector, and is in the possession of Mr. Wollaston. 
104. conjunctum (M.). .A very dwarf pretty form. The fronds 
are six to eight inches high, an inch and a half broad near the 
base, dividing about half way up into two divisions, and these 
becoming again forked with multifid apices ; the margins are undu- 
lated, and the multifid apices of the lobes have their points twisted 
as in crista-galli (142). It was found by Mr. James in Guernsey, 
and maintains its peculiar features. 
105. complicatum (Woll). This is a very neat and interesting 
variety. The fronds are six inches to a foot or more in length, 
cordate, sometimes unequal at the base, simple or multifid, with 
twisted lobesat the apex, sometimes forked in the costa with the 
branches crossing each other transversely; the margins irregularly 
crenate, somewhat laeiniately-toothed and undulated. The sori are 
numerous, in narrow approximate lines, which seem to have an 
irregular direction in consequence of the undulation of the margin. 
It was found at Chislehurst, Kent, by Mr. Wollaston. 
106. spirale (M.). This is a very curious dwarf variety. The 
fronds are from three to five inches long, the broadest about an 
inch in width, undulate im the lower part, and becoming twisted 
towards the top in a spiral or corkserew fashion. This, which proves 
to be a constant form, rather curious than beautiful, has been found
