VIII. ADIANTUM, Linnaeus. Maiden-Hair. 
Chiefly smooth ferns, i to 2^ feet high, of graceful aspect. Stalk 
black, polished. Final divisions never narrow. (Greek unwctted, the 
fronds shed rain because they are oily.) 
A genus of 67 species, mostly tropical. 
* Stalks forked. 
55. _A. pedatum, L. (The A. like a foot.') 
Rachises bearing, on the outside, 6 to 14 pinnate divisions; pinnules 
oblong, lobed or cleft, short-stalked ; main vein running along the lower 
side of the pinnule which therefore appears one-sided. 
Common in the coast ranges; less frequent in the Sierras, where it reaches an alti- 
tude of 7,000 feet at Summit (Jones.) Very rare in the Rocky Mountains (Cottonwood 
Canyon, Utah; Watson). North to Unalaska and east to the Atlantic. Japan, etc. 
* * Stalks not forked. Fronds ovate to oval in outline, bi- to quadri- 
pinnate at base, simpler upwards. 
56. A. CapilillS- Veneris, L. (Latinized Maiden-Hair.) 
Final divisions wedge-shaped at base with nearly straight sides, 
obovate or broader, scalloped and finely toothed ; involucres separated, 
oblong. Fronds delicate, smooth, -usually drooping, upper half or third 
only pinnate. 
Around springs and in damp canyons; southern California, Arizona, southern Utah, 
southern States and various parts of the world. 
57. A. emarginatllill, Hooker. (The notched A.) 
Final divisions smooth or nearly so, almost semi-circular, sometimes 
wedge-shaped at the very base ; sides concave, slightly cut ; involucres 
almost continuous. Stalks rather stout. Not drooping. 
In canyons; from San Diego (California) to Oregon, in the coast ranges. 
58. A. tricliolepis, Fee. (The velvety A.) 
Final divisions hairy on both sides; involucres very velvety. Root- 
stock creeping ; with linear, acuminate, tawny scales. 
Rocky ravines. Western Texas to Yucatan. May have been collected by Nuttall 
at Monterey, California. 
TRIBE IV.-BLECHNET. 
IX. LOMAEIA, WiLLDENOw. Deer-Fern. 
Sterile fronds with pinnae rather broad ; veins free. Fertile fronds 
with very narrow pinnae ; veins often forming a series of meshes on each 
side of the midrib. (Greek for a border, on account of the long indiisium?) 
A genus of about 45 species, chiefly tropical. Evoi'green. 
59. L. 8pica,llt, Desvaux. (The pointed L.) 
Sterile fronds smooth, almost linear, tapering at both ends ; stalk 
scarcely any ; pinnae oblong or oblong-linear, curved upwards. Fertile 
fronds very narrow, long-stalked ; pinnae sessile by an abruptly widened
