56 J. SMITH ON THE GENERA OF TEUNS. 



pinnate, the fertile sometimes contracted, the pinnm more or 

 less distinctly articulated with the racMs, smooth, villose or 

 densely covered with scales, through which the sporangia 

 protrude. 



Ohs. This genus is readily distinguished from Goniopteris 

 by the sori being always produced on the apex of the lower 

 venule, or on the excurrent free veinlets which terminate in 

 the areoles; the latter are often sterile or absent: — then only 

 the costal areoles are soriferous and consequently they form 

 only one transverse row of sori. The peculiarities of habit 

 of the species forming this genus, admit of their being ar- 

 ranged under several sections which may, with no great im- 

 propriety, be considered as genera. 



* LoPHOLEPis. J. Sm. 



Rkizoma filiform. Fronds I to 4 inches high, squamose, 

 the fertile contracted. Sori uniserial, each furnished with a 

 dense tuft of elongated scales.

** Lepicystis. J. Sin. 



Rhizoma slender. Fronds linear, pinnatifid, from 3 to 18 

 inches high, densely covered with round or elongated scales, 

 through which the sporangia protrude, the scales forming a 

 calyciform indusium. Son uniserial.

Ohs. The venation of this group is difficult to be seen, but 

 the species are readily known by their squamose habit. 



*** SCHELLOLBPIS. /. StH. 



Rhizoma thick. Fronds 2 to 3 feet high, linear-pinnatifid, 

 or deltoid and pinnate, smooth. Sori uniserial, each furnished 

 with numerous, small, laciniated, shining scales.
