surface smooth or minutety granular ; lines of fruit forking, bursting through 

 the colored powder, and at length nearly obscuring it. — Enum. Fil. p. 73 ; 

 Hook, & Grev. Ic. Fil. t. 153 ; Hook. Fil. Exot. t. 10. 



Common in California, and said to occur as far northward as Vancouver Island, and to reappear 

 in Ecuador. The plant from New Mexico referred to in the Botany of Whipple's Expedition, p. 160, is 

 probably Notholana Booktri, which bears -a considerable resemblance to small specimens of the present 

 species. Commonly called California Gold-Firn. The powder on the under surface of the frond is 

 usually a clear sulphur-yellow, but varies from deep orange to a pure white. In Hooker's Herbarium 

 are specimens from Nuttall, with three MS. names, G. Oregona, G. viscosa, and G. pyramidata. 



Gymnogramme hispida, Mettenius. 



Rootstocks creeping; stalks grayish, puberulent; fronds 5-angled, 1-3 

 inches long and broad, hispid above, tomentose beneath, chaffy like the 

 rachis with minute linear scales, pinnate ; lower pinnae much the largest and 

 unequally triangular, again pinnated ; pinnse and lower segments lobed or 

 crenated ; the lobes rounded and very obtuse, the basal ones adnate to the 

 rachis or midrib, and forming an interrupted wing, alternating with the 

 pinnse ; veins all free. — Kuhn in Linnsea, xxxvi, p. 72. G. podophylla, 

 Hook. Sp. Fil v, p. 152, in part. G.jpedata, Eaton in Robinson's Catalogue, 

 not of Kaulfuss. 



New Mexico (C. Wright, Mrs. Sumner), Arizona (Clarence King), and at the Chiricahua Mts., Dr. 

 Koihrock. — This comes very near to G. pedata, Kaulfuss, with which I have heretofore confounded it ; 

 but it is sufficiently distinguished by the rounded segments, and especially by the decnrrent basal lobes, 

 which form an interrupted wing on the main and secondary rachises, much as in Phegopteris polypo- 

 dioides. 



III. N0TH0L.ENA. R. Brown. 



Sori on the veins at or near their extremities, roundish or oblong, soon 

 more or less confluent into a narrow marginal band, with no proper invo- 

 lucre, but sometimes covered at first by the indexed edge of the frond. 

 Veins always free. Fronds of small size, 1-3- or 4-pinnate, the under sur- 

 face almost always either hairy, tomentose, chaffy, or pulveraceous. 



A genus of less than forty species, most abundant in dry, rocky places from New Mexico to Chile, 

 but two are Mediterranean, and a few occur in South Africa, Australia, etc. The genus borders closely 

 on Gymnogramme on the one hand, and on the other is barely distinguishable from those species of Chci- 

 lo.nlhes in which the involucre is not well developed. 



*Frond minutely scaly beneath. 



IVotholaena sinuata, Kaulfuss. 



Rootstock short and thick, very chaffy with narrow rusty scales ; 

 fronds 6 inches to 2 feet high ; narrow and rigid, simply pinnate ; pinnse
