Mr. Hen d e rso n has a variety (figured on plate iv) w hich is
very distinct, and which I have figured under the name of
variety Henclersoni. Cultivated in the Wentworth collection
for some years, and in all probability originated there. Although
very différent from the normal state, still it would be difficult
to draw up a description which might not apply to both
forms in different states of growth. L e t it suffice therefore to
mention its chief differences. In the normal state the length
of the frond is from two to three feet, whilst in the variety
Hendersoni it attains the length of from four to five feet. In
the variety the pinnæ are much narrower and longer, and
terminating in a narrow attenuated apex. In both forms the
two lower segments are the longest, b u t more decidedly so
in the variety.
]\Iy thanks are due to Mr. Masters, of Cante rbury, for
plants of this species; and to Mr. Moore, of Chelsea, and to
Mr. Henderson, of Wentworth, for fronds.
