Guernsey by Mr. Jackson. This variety has produced irregularly’ 
inciso-laciniate fronds in Mr. Wollaston’s garden. 
94. crispum minus (Jackson). A very elegant small much-curled 
variety, with fronds nine or ten inches long, exclusive of the shortish 
stipites, and measuring about an inch and a half in width; they 
are cordate or sub-cordate and somewhat marginate and toothed at 
the base, frilled and toothed at the margins, which are nearly 
parallel, with a short acute or sometimes multifid point. It was 
found by Mr. Jackson in the island of Guernsey. 
95. crispum varians (M.). This is a broad and variable form, the 
fronds sometimes resembling crispum latum (92) with a simple acute 
apex, sometimes truncate, sometimes multifid or even ramose some 
distance down the costa—all these forms being perfect and evenly . 
frilled. It also produces fronds which are completely irregular, 
being interruptedly lobed, with a very uneven margin, and less per- 
fectly crisped. It is moreover, freely proliferous, producing bulbils 
every season. This form, a very handsome one, was found near 
Settle by Mr. A. Clapham of Scarborough. A multifid form of 
erispum has also been sent from Barnstaple by Mr. Jackson. 
96. crispatum (M.). This is a moderate-sized very much curled 
variety, and is chiefly remarkable beyond this, among the forms of 
the true crispum character, for being abundantly fertile. The 
fronds are about a foot long, an inch and a half or when very 
luxuriant two inches and a half broad, cordate at the base, almost 
parallel-sided, closely frilled, with an acute or sometimes lobed apex. 
When growing in a pot and rather starved, we have had it produce 
narrow fronds, five to seven-eighths in width, slightly erisped, 
and loaded with sori, but this is not its usual character. It was 
found by Mr. James in Guernsey, and is very beautiful. 
97. crispatum varians (M.). A very elegant and variable fertile 
form, allied to the Guernsey crispatum. Its spring-formed fronds 
are eight to ten inches long, and about an inch and a half broad, 
lobate and subtruncate and unequal at the base, the margin undu- 
lated and dentate, and the apex slightly dilated or multifid. The 
autumnal growth is broader; three inches wide, the margin fringed 
with smallish acute projecting lobes or enlarged teeth, similar to 
those of Zaceratum (145); portions of both these forms of frond are
