CHARACTERS OF TRIBES AND GENERA, 307 
linear, continuous on the costal anastomose, elevated in 
the form of a ridge. Indusium linear, laterally attached 
on the exterior side of the receptacle, its inner margin 
free, becoming reflexed, coriaceous, persistent, 
Type. Sadleria cyatheoides, Kaulf.

Oss.— The type of this genus was originally described as 
a species of Blechnum, under which genus I placed it in 
1841, my first arrangement, but on account of its very 
distinct habit I now deem it best to separate it from 
Blechnum. With Lomaria Boryana it agrees in having 
a stout arborescent caudex, but differs in having regular 
pinnatifid pinnæ, which are articulate with the rachis.

Natives of Sandwich Islands. S. pallida, Hook. and Arn. ; 
S. Souleytiana (Gaud.) and S. Kaulfussiana (Gaud.) are 
considered to be only different states of S. cyatheoides,

Hook. Sp. Fil., Bowringia Hook. (1853) non Benth. 
Vernation fasciculate, erect, arborescent, 2 to 4 feet high. 
| Fronds pinnate, rarely sub-bipinnate, 2 to 34 feet long ; 
B. inns linear lanceolate, 4 to 6 inches long, sub.sessile, 
base truncate above, auriculated below; margin crenate 
Serrulate. Veins flabellately forked, free exteriorly, the 
. lower venules short and angularly anastomosing, forming 
. ® row of oblique costal areoles. Sporangia produced on 
_ the angular anastomoses, and lower part of the exterior 
_ free venules, confluent, constituting a broad, compound, 
continuous or sub-interrupted, transverse naked sorus.
