Genus. — Ai^losoeus, Bernhardi. 



Mid-vein distinct, lateral veins free : involucre not ap- 

 parent : capsules in circular clusters near the extremity of 

 the lateral veins, which are often divided : epidermis pro- 

 longed, bleached, reflexed, entire, and covering the cap- 

 sviles in the manner of an involucre.

Genus. — Ctenopteris. 



Mid-vein distinct : lateral veins of the pinnae or pinnules 

 branched, free, swollen or capitate at their extremities ; the 

 anterior branch simple, generally terminating midway be- 

 tween the mid'vein and the margin, bearing a cluster of 

 capsules at its extremity ; the posterior branch is twice or 

 thrice dichotomously divided, the capitate extremities usu- 

 ally forming a line parallel to the margin : involucre none : 

 rhizoma usually attached by means of its roots to the sur- 

 face of a rock, the bark of a tree, &c., thus always having 

 a pseudo-parasitic or climbing appearance, cylindrical, 

 branched, extending itself at the extremities, at first dense- 

 ly clothed with palese, but as these fall off becoming smooth 

 and naked ; of slow growth, tough and very enduring, here 

 and there marked with nearly circular scars, the site of 

 fallen fronds, which, though persistent through the winter, 

 are deciduous in early summer, falling off at a basal articu- 

 lation. (See Phytol ii. 274).
