1 10 Errors in Southern California Plants. [zoe 



mountains, for example — perplexity arises, and even incredulity, 

 and it becomes of importance to make sure that no mistake has 

 been made. 



To correct some ascertained errors of this kind, and to call at- 

 tention to other probable ones, is the chief object of the present 

 paper. Besides this it seems desirable to rectify some mistakes 

 which have been made in recording the type-stations of certain 

 species, and to eliminate from the southern Californian flora some 

 species which have been accredited erroneously to it. 



Errors such as these arise from several causes. Some occur 

 from a pardonable ignorance of local geography, a.misapprehen- 

 sion which led Brewer and Watson to include in the Californian 

 flora a number of plants from Ft. Mojave, a station which is 

 really in Arizona. Sometimes plants have been supposed by the 

 botanists who received them to have grown at the collector's res- 

 idence, or at the place whence he forwarded them, and in this way 

 several of Dr. Parry's type-specimens have been located incorrect- 

 ly. Other errors originate in mistaken identifications, which 

 once finding their way into print are too apt to be repeated by sub- 

 sequent writers. Less excusable are the blunders due to the 

 negligence of collectors in supplying proper data with their speci- 

 mens, or the carelessness of authors in noting the labels of 

 herbarium sheets. 



ASPIDIUM ACTJI^ATUM PROUFERUM Wolleston. 



Dr. Eaton 1 notes this fern as "very abundant in the southern 

 part of the state, and commonly called the 'San Diego fern,'" 

 but I do not find that any of our resident botanists are aware of 

 its presence, or have heard the supposed trival name. The only 

 variety of this species which is known from southern California 

 is the var. scopulinum, collected at a single station in the San 

 Bernardino mountains. 



Bromus depatjperatus Presl, Rel. Haenk. 11.263. 



To this species Dr. Beal refers specimens said to have been col- 

 lected at San Diego by Bolander, and by Kellogg;" but Mr. Shear,
