CATALOGUE. 333 



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. 



Western Texas, Wright, Lindheimer. Near Santa Barbara, California, Mrs. Cooper, Dr. Eothroch. 

 A specimen 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. 



Aspidinm 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 nan-owed towards the base, sub-bipinnate; 

 pinnae 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 Colum- 

 bia and Dakota Territory to Lake Superior and Canada. Newfoundland, fide Kunze. If all the 

 forms referred to the male Fern by Hooker really belong to it, the species is found in Europe, Asia, 

 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. Eoy, 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 A. cristatum. Nephrodium Floridanum, Hooker, Fil. Exot. t. 99, is 

 afterwards referred to Filix-mas by the illustrious Botanist who named it, but it seems to be rather a 

 form of A. cristatum. 



Aspidium rigidum, Swartz, var. arguf urn. 



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
