several irregular rows between the midrib and margins. — Linnsea, xx, 

 p. 363. Hooker & Baker, Syn. Fil. p. 257. 



A few specimens of a small form with free veins, answering to Aspidium pumilum (Martens & 

 Galeotti, Fil. Mex. p. 64, 1. 17, f. 1), were collected at the Hueco Tanks in Western Texas, and at Van 

 Horn's Well, by the Botanists attached to the Mexican Boundary Commission in 1852, but the plant has 

 not been collected within the United States since that time. 



It is a common species in Mexico and Tropical America, and includes many nominal species as 

 well as two genera, Amblya of Presl and Phaneropheoia of Presl and Fee. 



XIV. CYSTOPTEBIS. Bernhardi. 

 Cystopteris frag ills, Bernh. 



Common in rocky places from the Arctic regions to Chile in the west, and to South Africa and 

 Tasmania in tho east, everywhere variable in size, and in the breadth of the segments and the degree of 

 their incision. 



CYSTOPTERIS MONTANA, Bernh., with deltoid-ovate, delicately tripinnate, and almost quadri- 

 pinnate fronds, and a long, slender, creeping rootstock, was collected many years ago in the Eocky 

 Mountains of British America by Drummond, and more recently on the north shore of Lake Superior by 

 Macoun, and in Labrador by Eev. B. S. Butler. It may possibly occur in California or Colorado. 



XV. WOODSIA. R. Brown. 



Woodsia scopulina, D. C. Eaton. 



Rootstocks short, creeping, entangled, very chaffy ; stalks 2-4 inches 

 high, from bright ferruginous near the base becoming paler upwards, puber- 

 ulent like the rachis and under surface of the frond with minute flattened 

 hairs and stalked glands ; fronds lanceolate, 4-8 inches long, pinnate ; pinnse 

 numerous, 8-10 lines long, oblong-ovate, pinnatifid with .0-16 short ovate 

 or oblong crenulate or toothed divisions ; sori submarginal ; indusium very 

 delicate, deeply cleft into lacinise, which terminate in short hairs composed 

 of irregular cylindrical cells. — Canadian Naturalist, Apr. 1865, p. 90. Bot. 

 of 40th Parallel, p. 397. 



Oregon (Bracleenridge, Hall, Wood), and iu Mono Pass, California, at 9,000 to 10,000 feet elevation 

 (Bolander), to Dakota and Minnesota in the north, and southwards to Arizona (Palmer) and Colorado, 

 growing in dense masses on rocks and iu their crevices. It has been collected also in British Columbia.. 



Woodsia Oregana, D. 0. Eaton. 



Much like the last in size and habit, but the stalks and fronds smooth ; 

 fertile fronds taller than the sterile ones ; pinnse triangular-oblong, obtuse, 

 pinnatifid ; segments oblong or ovate, obtuse, toothed or crenate ; the 

 teeth often reflexed and covering the submarginal sori ; indusium very
