POL.YPODIACEAE 



/ PoivYSTiCHUM MUNiTUM iMBRiCANS (D. C. Eaton) Maxoii, Fern 

 Bulletin, 8: 30. 1900. 

 Aspidin^n inunitum var. imbricans D. C. Baton, Ferns N. 



A. 1: 188.//. 25. f. 3. 1878. 

 No, 8061, collected June 17, on bare rocks with a southerly 

 exposure, overlooking a deep gorge near the source of the Sac- 

 ramento river west of Sisson, Siskiyou county. The original 

 specimen was collected by Kellogg in Mendocino county. 



It is to be hoped that observations may be made so as to 

 determine whether this fern ever occurs in comparatively moist 

 situations or on northerly slopes. The writer collected it once 

 before, under no. 5932, in Lake county, growing in dry gravelly 

 ground on southerly slopes, but the plants were larger, being 

 shaded more or less by a scattered growth of trees. 



Pellaea ornithopus Hook. Sp. Fil. 3: 143.//. 116 A. 1858. 

 No. 7816, collected May i, near Keene Station, in the Te- 

 hachapi mountains, growing about stones and rocks on a grassy, 

 sparsely wooded slope. The species seems to be pretty well dis- 

 tributed over the State, occurring at medium elevations. The 

 type was collected in California. 



MARSILEACEAE 



Marsilea vestita Hook. & Grev. Ic. Fil. 2i: pi. i^g. 1831. 



No. 7919, collected May 31, in damp sand along the Sacra- 

 mento river, about two miles above Redding, Shasta county. 

 It was plentiful and of thick growth, the slender rootstocks often 

 two or three feet long, lightly covered by the wet sand. 



SELAGINELLACEAE 



Selagtnella bigelovii Underw. Bull. Torr. Club, 35: 130. 

 1898. 

 No. 7610, collected April 7, on rocks at the first railroad
