OPHIOGLOSSUM CALIFORNICUM IN 

 CENTRAL CALIFORNIA. 



By S. B. Parish. 



In a collection of plants sent by Mr. Ernest Braun- 

 ton from lone, Amador County, there were some fine 

 specimens of Adder's tongue, which proved to be Ophio- 

 glossuni Calif ornicum Prantl. This species has been 

 known heretofore only from the neighborhood of San 

 Diego, and from a station in adjacent Lower California. 

 Mr. Braunton's interesting discovery now carries it some 

 500 miles to the north, and from the seacoast inland to 

 the base of the Sierra Nevada. The difference in alti- 

 tude is less marked, that of San Diego not exceeding 50 

 feet, while that of lone is 500 feet. 



Mr. Braunton's specimens were collected in December 

 last, and he reports the plants as very plentiful. They 

 were larger than any San Diego specimens I have seen, 

 the largest being four inches tall. This greater develop- 

 ment is probably due to the more abundant rainfall at 

 lone. 



It is an interesting coincidence that Jcpsonia Parryi, a 

 little saxifragaceous plant, which also is peculiar to San 

 Diego, should reappear at lone. At San Diego this plant 

 is not as narrowly localized as the Ophioglossum, since 

 it is found over much of the country, but like it, it occurs 

 at no intermediate point.

There is probably no genus in the world more dis- 

 tinctly marked than Adiantuni, to which the maiden-hair 

 ferns belong. The peculiar one-sided pinnules with the 

 main rib running along the lower margins, and the 

 oblong sori concealed under overlapping lobes of the
