CHARACTEES 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 re flexed, coriaceous, persistent. 



Type. Sadleria cyatheoides, Kaulf.

OBS. 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 pinnae, which are articulate with the rachis.

Natives of Sandwich Islands. S. pallida, Hook, and Am. ; 

 S. Souleytiana (Gaud.) and 8. Kaulfussiana, (Gaud.) are 

 considered to be only different states of S. cyatheoides.

Vernation fasciculate, erect, arborescent, 2 to 4 feet high. 

 Fronds pinnate, rarely sub-bipinnate, 2 to 3 feet long ; 

 pinnae 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 

 a 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.
