1. capitatum, Lowe (Pulleri-capitatum, Jones). Raised by Mr. 
F.. F. Fox. A capitate Pulleri. 
*2. cymbaforme, Lowe. Raised by myself. A cross between 
Pulleri and cruciatum. In lower half of fronds, which are lax, each 
pair of pinnm curve upwards and assume the shape of a boat ; 
above the middle of frond cruciate, and towards the apex 
Frizellice-like. The upper half of each pinna is lunulate, terminating 
in a large lunulate pinnule, as broacf as the rest of the frond. 
20 X 4 inches at base, and 20 X oj inches near apex.

the Isle of Skye by Mr. C. Puller. Length, 18x3 inches. Very 
lax, pinnae short and narrow, with lunulate pinnules ; tip of frond 
caudate. A distinct fern. I have raised a form from this, fronds 6 
inches broad, and pinnules of double the size of Pulleri.
