224 34. DAVALLIA. § 2. COLPOSOEIA. 



(16) D. fructuosa. Chfist. 



Rhizome scales filiform (from a suddenly dilated base ?) ; lowest pinnae 

 equal-sided at the base (i. e. with the lowest posterior pinnula not 

 produced); upper surface rather blackish (dark-grey?) when dry; indusium 

 short- or long-semicylindrical. 



(17) D. tricbomaaoides, Bl. 



Rhizome scales brown or ferrugineous, linear-subulate, spreading, pro- 

 bably more or less deciduously ciliolate, narrowed more or less gradually 

 from an oblong, peltate, adpressed base; soriferous lobules dilated from a 

 cuneate or hnear base into a clavate-oval, truncate and emarginate, often 

 1 — 2-dentate or corniculate apex; indusium ± l'/^ — 2 X as long as 

 broad, urceolate, constricted at or below the apex, the apex whether or 

 not reaching the margin of the lobule. — I think this to be hardly different 

 from D. dissecta J. Sm.

 oblong, acuminate, copiously and deeply 2-pinnatiM ; pinnae more or less 

 opposite, horizontal or nearly so, triangular-lanceolate, straight or sub- 

 falcate, acutely acuminate, to 2'/2 cm. broad at the truncate or sub- 

 truncate base, the lower shortly petiolulate; segments somewhat obhque, 

 acute or subacute, serrate, the barren elliptical-oblong, close, the fertile
