it, and bearing the sporangia on its under side on the free ends of 
several simply forking veins. Midrib none, or lateral. - Stalk and 
raehis black and polished. (The ancient name, from a privative 
and &mVa>, to moisten, the smooth glaucous foliage repelling the 
rain-drops.) 
1 A. pedatum, L. Frond forked at the summit of the ud- 
right slender stalk (9'-15'high), the forks pedately branching from 
one side into several slender spreading divisions, which bear numerous 
triangular-oblong and oblique short-stalked pinnules; these are as if 
halved, being entire on the lower margin, from which the veins all 
proceed, and terminate in the cleft and fruit-bearing upper margin — 
Rich, moist woods. July. A delicate and most graceful Fern. 
6. CHEILANTHES, Swartz. Lip-Fern. 
Fruit-dots roundish, solitary or contiguous on the margins of the 
lobes ; the usually kidney-shaped indusium fixed to the margin 
at the point where the sporangia arise, free along the inner 
edge, each receiving but one (direct and free) vein or veinlet. 
Fronds 2-3-pinnate, the pinnules or lobes with a central midrib. 
(Name composed of %ei Xov, a lip, and av6os y flower, from the shape 
of the indusium.) 
1- C# vestlta, Willd. Fronds 2-pinnate, hairy all over (6 / -9 /

7, WOOD WAR DI A, Smith. Woodwardia. 
Fruit-dots oblong or linear, approximate or contiguous, parallel 
to the midrib or transverse anastomosing veinlets, in one or rarely

sium fixed to the outer margin of the veinlet, free on the side next 
the midrib. — Fronds pinnatifid or pinnate. (Named for Wood¬ 
ward , an English botanist of the last century.) 
§ 1. Woodwardia proper. — Indusium vaulted and the free edge in¬ 
volute : veins (at least of the sterile frond) with several rows of reticu¬ 
lations. 
1. W. ailgustifolia. Smith. Sterile fronds (1° high, thin, 
bright green) deeply pinnatifid, with lanceolate serrulate divisions; 
the fertile simply pinnate; pinnae contracted, linear (2 , '-4" wide), 
with only one row of cross veins, bearing the fruit-dots (£' long) as near
