ScMzcea cristate, Willd. Spec. PI. 5, p. 88. 



Hab. Tahiti, Society Islands. Feejee Islands. 



Related to the preceding species in habit ; but altogether a much 

 handsomer species. Fronds repeatedly dichotomous, and flabelliform 

 in circumscription; the segments linear, compressed, slightly sca- 

 brous, attenuated at the point, with a prominent midrib. Fertile 

 appendages small, suberect, with 4 or 5 pairs of pinnae, having an 

 indusiiform crinite margin. 



91. ACTINOSTACHYS, Wall 



(Scmz^as Spec. Sw., Schk.) 



The genus Actinostacliys, as here adopted, differs from true ScJiizcea 

 in the fertile appendages being digitate, and in the quadriserial dispo- 

 sition of its sporangia, that is, they are arranged in two rows on both 

 sides of the costa of the segments.

ScJiizcea digitata, Sw. Syn. Fil. p. 150 & 380, t. 4, f. 1 ; Willd. Spec. PI. 5, p. 87; 

 Blume, Enum. PL Jav. 2, p. 255. 



Hab. Feejee Islands. Mountains near Banos, Luzon, Philippine 

 Islands. 



This has a habit similar to that of ScJiizcea trilateralis of Schkuhr, 

 and might readily be mistaken for it, but for the broader fronds, the 

 more erect fertile appendages, and the entire absence of the chaffy 

 hairs, intermingled with the sporangia in that species.
