112 Errors in Southern California Plants. [zok 



collected at Los Angeles Bay, on the gulf coast of Lower Califor- 

 nia. 



Muhlenbergia gracilis Trin. Unif. 193. 



By a confusion of names this grass was included in Mr. Bran- 

 degee's list of Santa Catalina plants, u M. debilis Trin. (M, micro- 

 spertna Trin.) being intended. M. gracilis is not known from the 

 southern part of the state. 



Orcuttia Californica Vasey, Bull. Torr. Club, 13: 219. 



This species has been reported as extending into California, 111 

 but I cannot find that there are any specimens from the American 

 side of the boundary. All those in the National Herbarium are 

 from Lower California. 



Sisyrinchium Caeifornicum Ait. f. Hort. Kew. Ed. 2, 4: 135. 



5. lineatum Torr. is a synonym of this species, and in his note 

 on it, Dr. Torrey states that it was "first detected by Dr. Parry, 

 who found it near San Diego. " u The type, however, is a speci- 

 men collected by Dr. Parry, in April, 1850, in Monterey County, 

 which is still preserved in the herbarium of Columbia University.'"' 

 No representative of his San Diego plant is known to be in ex- 

 istence, nor have subsequent collectors met with the species so far 

 south. There are numerous errors in the reported stations of Dr. 

 Parry's plants, and that of San Diego for this one is probably to be 

 included among them . Monterey County may be regarded as the 

 authentic southern limit, so far as our present information goes. 



Urtica Breweri Watson, Proc. Am. Acad. 10: 348. 



Los Angeles is the type-station of this species, and the type is 

 95 Bretver, in the Gray herbarium. On the label is the note: 

 "Everywhere in waste places about Los Angeles." In recent 

 years Los Angeles has been the residence of several zealous 

 botanists who have diligently sought to rediscover Brewer's 

 plant, but without success. It is probable, therefore, that 

 Brewer was in error as to its supposed abundance, having mis- 

 taken, perhaps, the common U. holoseticea Nutt. for it. Whether 

 his type really came from Los Angeles is also open to doubt. The
