projects downwards and forwards in a plane anterior to the rachis, 
and both are somewhat contorted —so as to embrace between them 
the rachis and to give the appearance of a twisted cable running 
up the rachis from below upwards.” 
Perhaps the most remarkable sport of the cruciate class, and it 
is remarkable that after an interval of twenty years, precisely the 
same variety should have been found in another part of Ireland. 
Mrs. С. Frizell has kindly supplied the following interesting 
account of the original discovery. “I found it on our own property 
in a most beautiful reach of the Avonmouth river, which runs from 
Lough Dan, through this place (Castle Kevin, Co. Wicklow.) It 
was in the year 1857; it grew between two large boulders so fast 
and with apparently so little soil, that it was with great difficulty 
my husband removed it. I don't think I ever saw any plant of the 
Frisellie so perfect as the original ; there were about eight fronds, 
none of them with those sports and irregularities one has since 
seen on it. I watched it for two years by Ше river-side, and it 
never had any appearance of seed, so we gave it to Mr. Bain, of 
the College Botanic Gardens, who put it into the hot-house, where 
it seeded immediately." 
The following account of the second discovery has been supplied 
by Dr. Moore, of Glasnevin. 
“This variety has been again found this year in the Co. Donegal, 
near Letterkenny, by Henry Chichester Hart, Esq., son of the 
Vice-Provost, Trinity College, Dublin, who accompanied the last 
Arctic Expedition as Naturalist. The two finds were exactly 
similar in form in every way. A wild frond from Mr. Hart’s plant 
was sent to Mr. Moore, of Chelsea.” Mr. Moore, of Chelsea, 
writing in the Gardener's Chronicle with reference to this frond, 
says that he has no hesitation in identifying it with А. f. f. 
Frizellie. 
Mr. Hart states that “ there were several fronds on the plant, 
all perfect, and similar to that sent to Chelsea, which was fault- 
lessly typical.” | 
Probably no form has been more productive of varieties by seed 
than Zrizellie. Mr. Glover, whose experience in this direction is
