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

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

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



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

 yellowish, or yellow. 



•*- Fronds once pinnate, the pinna with sessile segments. 



\of hola'iia Candida, Hooker. 



Rootstock 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 pinna? 

 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 pinnae 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.

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

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

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

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

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

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