States. In one form or another, the common Brake occurs in almost every region of the earth. In 
Oregon and Northern California, it forms thickets as high or higher than a man’s head, and many acres 
in extent. The miners of California boil the young fronds, and eat them as a substitue for asparagus. 
Adiantum pedatum, Linn. © 
n moist, rocky places, from Santa Cruz, California, to Oregon and Washington Territory, a 
northward to Unalashka. Wahsatch Mts., Utah. Common in the Atlantic States from North Carolina to 
Canada. It also occurs in Japan and Mantchooria, but does not appear to have been found among the 
mountains of Colorado, where it might reasonably have been expected. 
Adiantum Capillus-Veneris, Linn. 
Stalks and rachises very slender, nearly black, polished; frond ovate- 
lanceolate in outline, very delicate, smooth, bipinnate or sub-tripinnate, the 
upper half or third simply pinnate; pinnules and upper pinnze wedge-obo- 
vate or somewhat rhomboid, rather long-stalked, the sides nearly straight 
or moderately concave, the upper margin commonly rounded and more or 
less incised, crenated, or [in the plant of our district] acutely dentato- 
serrate, except where the margin is recurved to form the lunulate or trans- 
versely oblong separated involucres.—Sp. Pl. p. 1558. Hook. Sp. Fil. ii,

Plant with a short, creeping rootstock, the stalks very delicate, 4-8 or 10 inches long, sometimes 
erect, but more frequently drooping or pendulous ; frond 8-10 inches long, but in favored stations occa- 
sionally very much larger. The plant of the Gulf and Atlantic States is very similar to the European 
form, having the pinnules mostly sharply cuneate, often deeply lobed, and the upper or outer margin of 
the sterile pinnules crenated or obscurely toothed; but the plant of Utah, California, etc., differs in 
having the pinnules broader, firmer, less incised, wa the outer margin, if sterile, very acutely and finely 
toothed, the veinlets even slightly produced into minute needle-points. In all these points it shows a 
slight approach to the following. 
Adiantum emarginatum, Hooker. 
Stalks and rachises rather stout, nearly black, polished ; frond broadly 
ovate or deltoid-pyramidal, 2—3-pinnate, pinnules and upper pinne of 
ample size, rather long-petioled, smooth or nearly so, rounded or even 
reniform, the very base sub-cuneate, lower edges commonly a little con- 
cave, upper margin rounded, slightly incised; if sterile, acutely dentate, 
with the veins running to the points of the teeth; but when fruiting, with
