Part 1, 1909] SCHIZAEACEAE 43 
elongate fertile pinnae) 45-60 cm. long; stipe 28-38 cm. long, slender, subflexuous, stra- 
mineous, naked ; sterile lamina oblong-lanceolate, acutish, about 17 cm. long and 5.5 cm. 
broad, the rachis slender, flexuous; pinnae about 8 pairs, approximate or mostly apart, 
spreading, inequilateral, oblong to oblong-oval, obliquely exciso-cuneate below at the base, 
obtusely truncate above, the apex obtuse, the margins with an occasional crenation, other- 
wise irregularly fimbriate-crenulate, scarcely thickened; upper pinnae gradually smaller, 
the uppermost relatively narrower, very oblique, confluent at the slender apex; leaf-tissue 
papyraceous, duil-greenish and hispid with very short brownish hairs above, below slightly 
paler, glabrate and very minutely glandular, appearing pustulate by the contraction of the 
veins in drying; veins elevated above, scarcely so below; fertile pinnae 18-23 cm. long, erect 
or ascending, surpassing the sterile lamina, the panicle laxly short-branched, nearly gla- 
brous, much shorter than the slender subflexuous stalk. Sterile fronds similar but shorter, 
the stipe relatively much shorter. 
TYPE LOCALITY : Sierra Madre of northwestern Mexico. 
DISTRIBUTION : Known only from the original specimens (Seemann 1951). 
8. Anemia Donnell-Smithii Maxon, sp. nov. 
Rhizome and sterile fronds wanting. Fertile fronds ample, the sterile lamina as long 
as the stipe or longer; stipe relatively very slender, 20-25 cm. long, canaliculate, dark- 
stramineous, sparsely rusty-pilose, especially toward the base; sterile lamina oblong-lanceo- 
late, acutish, 27-29 cm. long, 9 cm. broad near the base, once-pinnate, the rachis slender, 
tusty pilose, glabrescent; pinnae about 14 pairs, approximate or contiguous, spreading, 
the lower ones about 4.5-5 cm. long, 2-2.5 cm. broad, opposite, rectangular-oval from an 
unequally and narrowly cuneate base, the upper side less oblique than the lower at the 
base, the apex obtuse, the margins finely and unequally fimbriate-crenulate, slightly thick- 
ened; upper pinnae very gradually smaller, alternate, all but the uppermost sessile, these 
ascending, semiadnate, spatulate, slightly decurved, greatly reduced, finally confluent and 
forming a slender lobed subcaudate terminal segment ; leaf-tissue papyraceor-membranous, 
above dark-green, glabrous or with a few very short minute hairs between the elevated 
veins, below lighter, glabrous, minutely and sparingly glandular, the veins immersed; 
fertile pinnae 11-21 cm. long, diverging at a wide angle from the much longer sterile 
lamina, the panicle pilose, a little shorter than the stalk, stout, with strong close branches, 
the lower ones apart; spores striate, not echinulate. . 
Type collected at Rio Permejo, Department of Santa Barbara, Honduras, altitude about 1800 
meters, December, 1888, C. Thieme, distributed by Capt. John Donnell Smith under xo. 5664 
(U. S. Nat. Herb. xo. 830288). . 
DISTRIBUTION : Known only from the type collection. 
9. Anemia hirsuta (1..) Sw. Syn. Fil. 156. 1806. 
Osmunda hirsuta I,. Sp. Pl. 1064. 1753. 
Rhizome horizontal, short-creeping ; fronds several, clustered, the stipe of the fertile 
fronds usually surpassing the sterile fronds. Fertile fronds (includiug the elongate fertile 
pinnae), 15-43 cm. long; stipe 5-27 cm. long, usually slender, stramineous or sometimes 
castaneous or darker (especially at the base), hirsute, glabrescent; sterile lamina oblong- 
lanceolate to ovate-oblong, or sometimes deltoid-ovate, 3-15 cm. long, 2-6 cm. broad, 
gradually narrowed toward the apex, pinnate; pinnae 6-14 pairs, remote or contiguous, 
spreading, acutish, the lower and miiddle ones truncate at the base above, cuneate and often 
widely excised below, subsessile, oblong to ovate-oblong, deeply and obliquely cleft into 
several subequal distant linear or narrowly cuneate segments, these irregularly toothed, 
the basal one sometimes broader; upper pinnae cuneate both above and below, narrow, 
scarcely incised, the uppermost confluent, forming a narrow cuneate terminal segment; 
leaf-tissue firmly herbaceous, lustrous above, paler below, pilose above, more laxly so and 
sparingly glandular below, striate in drying, the veins conspicuously elevated above ; fertile 
pinnae 7-23 cm. long, the stalk usually far surpassing the sterile lamina, the panicle usually 
close; spores cristate-striate, the ridges minutely echinulate or scabrous. Sterile fronds 
7-25 cm. long; stipe 2-14 cm. long; lamina similar to that of the fertile frond or often 
relatively narrower, sometimes a little larger.
