204 Southern Extension of Califomiia Flo^'a. [zoE 



Hosackia grandiflora Benth. var. anthylloides Gray. Saa 

 Pedro Martir. 



Hosackia deciimbens Benth. var. Nevadeiisis Watson. San 

 Pedro Martir. 



Hosackia crassifolia Benth. San Pedro Martir. 



Psoralea orbicularis Lindl. Along strearas among the foot- 

 hills of San Pedro Martir. 



Amorpha Califoriiica Nutt. San Pedro Martir. 



Ainorpha fruticosa L- Guadaloupe Creek. 



Astragolics circicDidafus Greene. Common on San Pedro 

 Martir. The growing plants are prostrate and the fruit lies 

 upon the sand in which it usually grows. The green pods are 

 fleshy after the fashion of A. Caryocarpus and the surrounding 

 margin which is said to be " quite peculiar " and suggested the 

 name of the species, appears only after drying. 



Prunus emarginata Walpers. San Pedro Martir. 



Rubies ursinus C. & S. Growing about the foothills of San 

 Pedro Martir. 



Fragaria Calif ornica C. & S. San Pedro Martir. 



Horkelia Californica Ch. & Schl. represented in northern 

 central California by broader leaved forms which have received 

 various names, as Potentilla Kelloggii Greene, P. elata Greene 

 and P. frondosa Greene (which appears to be quite the same as 

 Horkelia grandis H. & A. Bot. Beech. 339.) appears to diminish 

 the size of its leaflets as it recedes from the seabord or goes 

 southward. The southern and montane forms, P. Parryi Greene, 

 P. pttberula Greene, P. Clevclandi Greene and P. Lindleyi Greene 

 (the latter substituted for Horkelia cuneata Ch. & Schl. on 

 account of an earlier homonym, though there is an available 

 synomym, Horkelia Doiiglasiana Nutt. Bot. Beech. 33S.) reach on 

 San Pedro Martir a leaf form almost as narrow as in typical 

 Ivesia. There appears to be no character in the greater part of 

 these proposed species to warrant their retention even as varieties. 

 P. nudtijuga L,ehm. is described without mention of the stamens, 

 and including it in the synonymy of Horkelia Californica 

 necessarily infers that the artist who made the drawing was mis-
