Group III. Heteromorphum. 
Section a. ROTUNDATUM. (Rounded pinnules.) 
x. 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 pinnae curve upwards and assume the shape of a boat ; 
above the middle of frond cruciate, and towards the apex 
Frizelliae-like. The upper half of each pinna is lunulate, terminating 
in a large lunulate pinnule, as broad as the rest of the frond. 
20 X 4 inches at base, and 20 X inches near apex. 
*3. Fraseri, Lowe. Raised from spores by myself. Quite distinct 
from Pulleri, with larger and less rounded pinnules. Truncate 
and branched at the apex. Length, 22 inches, width, 2 1 inches. 
4. Pulleri, Moore (rotundatum, Wollaston). Found in 1864 in 
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. 
Section / 3 . LINEARE. (Narrow pinnules.) 
1. diminuato-pinnulum, Lowe. Raised by myself in 1884. 
18 X 7 inches. A slender variety, with very small, reduced pinnules, 
broader than long.

Rosshire by the Rev. Canon Girdlestone. Length, 21x9 inches. 
Pinnae ascending, linear or depauperate, especially near the rachis, 
where the pinnules are reduced to a thorn, or wanting. Apex of 
pinnules confluent. 
Section y. LACINIATUM. (Jagged pinnules.) 
1. arbuscula, Lowe. Raised by myself. 
* *2. Bellairsae, Lowe. A dwarf laciniate form. Found by Miss 
Bellairs. Length, 10 inches. Pinnae and pinnules diverse. 
3. conioides, Appleby. 
4. elegans, Lowe (laciniatum elegans, Stanspeld). A sport from

by cruciate pinnules. 
5. Fosteri, Lowe (laciniatum Foster, Jones). Found at Wood- 
head, in 1879, by Mr. Foster. An interesting laciniate Kalothrix- 
looking depauperate form. Pinnules cut into hair-like segments. 
15x5 inches. 
6. Jonesii, Barnes. Found in 1861, at Farleton Knot, by Mr. J.
