CLASS XXL CRYPTOGAMIA. 
ORDER I. FILICES. 
A. Capsule having an elastic ring at right angles with its opening. 
PoLYPO^DiuM. Capsules disposed in round, scattered fruit-dots, (or clusters of 
capsules,) on various parts of the lower surface of the frond ; involucrum 1. 
(poly pod.) 
Aspid'^ium. Capsules in scattered, roundish fruit-dots, on various parts of the 
whole lower surface of the frond; involucrum a kidney-form, or round mem- 
brane, fastened to the frond in or near the centre of the fruit-dot, and opening 
on all sides, or to one side of the fruit-dot, and opening on the other. I'he in- 
volucrum, when a little opened, is often peltate, (shield-fern.) 
Pter'^is. Capsules arranged in a continued line along the very margin of the

site sides meet and cover the lower surface, (brake.) 
Adian'^tom. Capsules disposed in oblong fruit-dots, arranged along the mar- 
gin of the frond ; involucrum is formed by turning back the margin of the frond 
over the capsules, and it opens inward. The lines of oblong spots are gene- 
rally along that margin, which may be considered the end of the leaf, or of the 
segments of the leaf, (maidenhair.)
