segments, the larger of these deeply and obliquely pinnatifid half way or nearly to the mid- 
vein into 2 or 3 pairs of broad unequally rounded lobes; upper pinnae gradually smaller 
and simpler, finally adnate, confluent at the crenate apex; leaf-tissue membrano-coriace- 
ous, light-green, lighter below, glandular upon both surfaces, inconspicuously fibrillose- 
hirsute, mainly along the veins of the lower surface; margins slightly thickened, a little 
recurved ; veins slightly elevated upon both surfaces ; fertile pinnae ascending or some- 
what divergent, stout, 6-11 cm. long, about one half the length of the sterile lamina, the 
stalk 3-3.5 cm. long, the panicle stoutish, with mostly short close divisions, the lower ones 
somewhat apart; spores immature. Sterile fronds 23-38 cm. long; stipe 10-21 cm. long; 
lamina 13-18 cm. long, 9-12 cm. broad, ovate, deltoid or subpentagonal by the basiscopic 
development of the lowermost pinnae, these ascending, unequally elongate-deltoid, with 
the inferior basal pinnules deltoid-oblong, 2-3.3 cm. long, 8-11 mm. broad; pinnules of 
the basal pinnae anadromous, of the other pinnae catadromous.

17. Anemia Karwinskyana (Presl) Prantl, Schiz. 99. 1881. 
Anemia villosa Karwinskyana Presl, Abh. B6hm. Ges, Wiss. V. 4: 343. 1845. 
Rhizome stout, decumbent or ascending; fronds closely fasciculate, the stipes of the 
fertile fronds barely surpassing the sterile fronds. Fertile fronds 32~38 cm. long; stipe 19 
~28 cm. long, erect, stout, flattish, light brownish-stramineous, clothed rather thickly with 
long subpersistent irregularly spreading brown hairs; sterile lamina deltoid, 10-11 cm. 
long, about 9 cm. broad, acutish, bipinnate, the rachis similar to the stipe; pinnae about 
9 pairs, contiguous, the lowermost and middle ones short-petiolate from a cordate base, 
ovate-oblong, obtusish, with about 5 or 6 pairs of mostly semiadnate rhombic-orbicular to 
oblong-ovate segments, these contiguous or half their width apart, obtusish, mostly 3- 
lobed, the larger ones crenately pinnatifid into 5-7 lobes ; upper pinnae gradually shorter 
and simpler, the uppermost adnate, confluent; leaf-tissue subcoriaceous, dull-greenish, 
scarcely lighter below, noticeably glandular upon both surfaces, laxly fibrillose-hirsute, 
conspicuously so over the whole lower surface; margins thickened, slightly revolute; 
veins elevated above, subimmersed below; fertile pinnae strict, erect, 12-14 cm. long, 
exceeding the sterile lamina, the stalk 2-3.5 cm. long, the panicle with numerous strict 
ascending divisions, the lowermost of these 2.5-3.5 cm. long; spores broadly striate, the 
angles not produced. Sterile fronds 24-27 cm. long; stipe 12-13 cm. long; lamina ovate- 
deltoid, 14-15.5 cm. long, 10-11.5 cm. broad; pinnae 9-11 pairs, approximate or the 
lowermost apart, these unequally deltoid-ovate, strongly basiscopic, the inferior basal pinnule 
about 2.3 cm. long with about 9 blunt triangular-ovate lobes, the superior basal pinnule trilo- 
bate ; middle and upper pinnae as on the fertile frond; pinnules of the basal pinnae ana- 
dromous, of the other pinnae catadromous. 
TYPE LOCALITY: Cristo, Mexico. .

Ornithopteris Wrightii Millsp. Field Col. Mus. Bot. 3: 14 (excl. description). 1903. 
Rhizome short-creeping, densely clothed with minute brownish hairs; fronds dimor- 
phous, obscurely distichous, closely fasciculate, the stipe of the fertile fronds far exceeding 
the sterile fronds. Sterile fronds 5-11 cm. long, laxly ascending ; stipes slender, stramine- 
ous from a darker base, 3-7 cm. long; lamina narrowly ovate or somewhat deltoid, 3-6 
em. long, 2-3 cm. broad, bipinnate at the base; pinnae 3 or 4 pairs, remote, decreasing 
gradually toward the apex of the lamina, the upper ones narrowly cuneate, strongly ascend- 
ing and confluent at the acutish apex, the middle and lower ones short-petiolate and slightly 
ascending ; basal pinnae ovate from an unequally cuneate base, with 1 or 2 pairs of sub- 
sessile narrowly obovate long-cuneate segments, these inciso-dentate at the apex; veins 
elevated on both surfaces; leaf-tissue firmly membranous, opaque upon both surfaces, paler 
and sparsely glandular below, very sparingly pilose both above and below between the
