TVotholaena Hewfoerryi, D. C. Baton. 



Eootstock covered with very narrow dark bristly scales ; stalks tufted, 

 3—5 inches long, slender, blackish-brown, when young woolly with a pale- 

 ferruginous tomentum ; fronds as long as the stalks, lanceolate-oblong, 

 covered, most densely beneath, with a web of very fine entangled whitish 

 hairs, tri — quadripinnate ; ultimate segments roundish-obovate, very closely 

 placed, ^— J a line broad, entire or slightly crenate ; sporangia rather large, 

 blackish, at length apparent in the mass of tomentum. — Bulletin of Torrey 

 Club, iv, p. 12. 



Near San Diego, California {Dr. Newberry, Prof. Wood, Mr. Cleveland). Temescal Range, Prof. 

 Brewer. Guadalupe Island, Dr. Palmer. It comes very near to N. Parryi, but is more compound, has 

 smaller ultimate divisions, and a decidedly finer and more matted covering. 



***Frond beneath pulveraceous, or coated with a fine powder, either white, 

 yellowish, or yellow. 



-*- Fronds once pinnate, the pinnae with sessile segments. 



Notholsena Candida, Hooker. 



Eootstock creeping ; the scales narrow, rigid, and nearly black ; stalks 

 tufted, 3-6 inches long, wiry, black and shining ; frond rather shorter 

 than the stalk, deltoid-ovate in outline, pinnate ; the lowest pair of pinnae 

 having the lowest inferior pinnules elongated and again pinnatifid, three 

 or four next pairs of pinnae somewhat distant and clearly separated, lanceo- 

 late, pinnatifid into slightly curved oblong segments ; upper pinnee like the 

 segments of the middle ones ; segments green above, white-pulveraceous 

 beneath, except on the nearly or quite black midribs, the margin slightly 

 revolute, but not covering the line of dark-brown sporangia. — Sp. Fil. ii, p. 

 116, and v, p. 111. N. sulphurea, J. Smith, Botany of Voyage of the 

 Herald, p. 233 ; Baker, Syn. Fil. p. 373. — N. pulveracea, Kunze ; D. C 

 Eaton in Bot. of Mex. Boundary. 



Western Texas and New Mexico, C. Wright, 820 and 2124, Bigelow, Schott. Colorado Desert, Arizona, 

 Parry. Recently discovered in San Diego Co., California, by Mr. D. Cleveland and Miss A. E. Burbeck. 

 It extends throughout Mexico and as far as Peru and Chile. — This Fern has many names besides those 

 quoted above. It seems to have been first named Pteris sulphurea by Ca,vanilles, from a form with 

 yellow powder, not rare in Central America, but as its oldest name in the genus Notholmna is Hooker's, 

 I do not see the propriety of going back with Messrs. Smith and Baker to the name sulphurea.
