ler's vallicola may be found in a note at the end of his treatment 

 of said species (4), which note reads: "The var. bicolor ap- 

 proaches forms of L. nanus, and tends to unite the two species." 

 Now var. apricus is certainly nearer to nanus than is any other 

 member of the Micranthus group. 



Of course variations occur, but while I noted decided vari- 

 ations in the size of the flower, and of the plant as a whole, due 

 to apparent soil, moisture, or light relations, the shape of the 

 floral parts were satisfactorily constant and distinctive. Hence, 

 as soon as I had satisfied myself concerning the status of each 

 of the forms mentioned below, I accepted it as distinct, and used 

 Greene's unpublished name for it. 



My numbers jpp, 723, 1374, /jpj, 1404, 1426, and 1427 

 are all L. vallicola abricus from about Stanford University, col- 

 lected in April and May, 1905 and 1908. Numbers 1297a and 

 T485 are from Hall's valley, Mt. Hamilton range, 1600 and 1750 

 feet elevation, and collected 10 May, 1907, and 17 June, 1908, 

 respectively. 



Lupinus bicolor Lindl. Bot. Reg. 13://. //op. 1827. 

 Mr. Heller's notes in Muhlenbergia 2: 292, led me to look 

 for this plant where noted by him. I found it abundant along 

 the railroad near Ocean View, and back of the cemeteries, south- 

 east of Col ma. Sheet 82223, University of California herbar- 

 ium from San Francisco is this species, and is so labeled, deter- 

 mined by E. L. Greene, C. F. Baker, collector. I have com- 

 pared my specimens with the original description and plate, and 

 accept the above determinations. My numbers /4/8 and //.?.? 

 are from "back of Cemeteries," San Mateo county, 26 April, 

 1908. 



Lupinus trifidus Torr.; Wats. Proc. Am. Acad. 12: 250. 1877. 

 A species not apt to be confused with any of its relatives. 

 It is also variable in size; at Pacific Grove the flowers as well as 

 the seeds averaging much smaller than in the San Francisco 

 specimens. It was found growing with L. bicolor near San 

 Francisco, the two forms commonly sharing the same ground, 

 with their branches intermixed. As a rule, a mere glance was
