crowded, obliquely oblong, acutish, basal ones longest; veinlets very evi- 
dent, simple, the lowest ones of adjoining segments sometimes uniting, and 
sending a short free veinlet to the sinus between the segments; sori near 
the margin; indusia very pubescent.—Syn. Fil. p. 49.

A seaiteson 3 is preserved in the Hookerian herbarium marked “ San Francisco, Calif., Dr. Sinclair,” but 
no one seems to have collected it near that city in recent years. The species occurs also in Florida and 
throughout Tropical America, and has been found also in various warm regions of the Old World. 
** Texture firmer, or sub-coriaceous, veins forking freely. 
Aspidium Filix-mas, Swartz. 
Rootstock short, stout, ascending or erect; fronds in a crown, on very 
chaffy stalks, half-evergreen, firm-membranaceous, 1-3 feet high, broadly 
oblong-lanceolate, slightly narrowed towards the base, sub-bipinnate; 
pinne from a broad base lanceolate-acuminate, pinnatifid almost to the 
midrib or again pinnate; pinnules oblong, smooth, palish beneath; in 
smaller fronds obtuse and sub-truncate, slightly toothed; in larger ones 
more elongated and pinnately incised; sori large, near the midvein, com- 
monly only on the lower half or two-thirds of each segment; indusia 
convex when young, rather firm, smooth, orbicular-reniform, with a deep 
narrow sinus; rachises more or less setose-chaffy ; chaff of the stalks bright- 
brown, of broad lanceolate-acuminate scales—Syn. Fil. p. 55. Nephro-

Mountains of Colorado, Dr. Scovill, Hall § Harbour, Brandegee. Rocky Mts. of British Colam- 
ia and Dakota Territory to Lake Superior and Canada. Newfoundland, jide Kunze. If all the 
Africa, North and South America, the Hawaiian Islands, Japan, and Ceylon. Some of the Colorado speci- 
mens, and those sent from Owen Sound, Canada, by Mrs. Roy, are very large and fairly bipinnate, with 
deeply incised pinnules, and therefore belong to var. incisum of Moore. This species is given in Pursh’s 
Flora as found from New Jersey to Virginia; but his specimens preserved in the Hookerian herbarium 
are partly A. Goldieanum and partly 4. cristatum. Nephrodium Floridanum, Hooker, Fil. Exot. t. 99, is 
afterwards referred to Filiz-mas by the illustrious Botanist who named it, but it seems to be rather a 
form of A. cristatum 
Aspidium rigidum, Swartz, var. argutum. 
Rootstock short, stout, ascending or erect; fronds in a crown, on 
chaffy stalks, half-evergreen, firm-membranaceous, smooth and green above, 
paler and more or less glandular beneath, 1-3 feet high, ovate-lanceolate
