be withont corers : nevertheless, we believe we have found un- 

 questionable indusia in the larger Canary Island species, and 

 some observers have even found, in the commoner one, a slightly 

 elevated membranous ridge, which no doubt represents this 

 part. We have ample authority for excluding the free-veined 

 Cape species from the genus.

Sori iudusiate, linear, often elongated ; approximate in parallel 

 and opposite pairs ; the receptacles on the anterior and posterior 

 sides of venules belonging to adjacent fascicles of veins. Ji«i«- 

 siwm linear, plane, membranaceous, each opening on its exterior 

 side, (with reference to the fascicle on which it is placed), so that 

 the twin sori open fece to face. Veins forted from a central 

 costa; venules direct, parallel, free, terminating in club-shaped 

 apices. 



Fronds thick herbaceous, simple or pinnate, frequently undu- 

 late lobate or multifid. Bhlzome short, stoutish, erect or de- 

 cumbent. — In some abnormal states of S. mtlga/re, the veins here 

 and there anastomose irregularly. The common species, S. 

 vulgaire, is one of the most prolific in varieties and monstrous 

 forms among tnown ferns.
