OPHIOGLOSSACEiE. 



Ophioglossum Calif ornicum Prantl. Discovered in January, 

 1850, by Dr. C. C. Parry, growing in grasses, stony places on the 

 high mesas near San Diego. It remained otherwise unknown 

 until rediscovered at the same place, and by the same botanist, 

 in March, 1882, and has been collected there frequently since. The 

 only other locality where it has been found is at Ensenada, in 

 adjacent Lower California, where it was collected by Jones and 

 by Pringle. It is said not to appear in very dry winters. 



Ophioglossum vulgare L. A specimen of this species 



is said to have been collected somewhere in California, but its 

 authenticity is doubtful. 



Botrychium silaifolium Presl. From Plumas county to the 

 northern boundary of the State. A specimen collected near Sis- 

 son by M. A. Howe is stated to have grown "in swampy woods" 

 at about 3,500 feet alt. 



Botrychium simplex E. Hitchc. At high altitudes (10,000 feet) 

 in the Sierra Nevada ; probably in the northern part only. 



B. Coulteri, B. lunaria and B. Virgianum have been re- 

 ported from California, but probably incorrectly. 



POLYPODIACE^E. 



Polypodium vulgare L. Near the coast, from San Francisco 

 northward; sometimes growing on the trunks of trees. 



Polypodium hesperium Maxon. Probably occurs, at high alti- 

 tudes throughout the entire length of the Sierra Nevada. In the 

 San Bernardino Mts. it is found at an altitude of about 9.000 feet, 

 or, under exceptional circumstances, as low as 6,000 feet. It 

 grows in the crevices of rocks. 



Polypodium falcatum Kellogg. This fern has been collected in 

 Trinity county, which seems to be its southern limit. North- 

 ward it extends to Alaska. It grows on tree trunks, or in rock 

 crevices. 



Polypodium Calif ornicum Kaulf. This species apparently 

 reaches us from the south. It has been collected on the peninsula 

 of Lower California by Brandegee, and on Guadalupe Island by 

 several botanists, while Gilbert has received it from Costa Rica. 

 It is especially abundant in the southern part of the State, and 

 while its northern boundary is uncertain, it probably does not 

 reach the Oregon line. The most northern specimen to our
