from Professor Abratns, the plant considered to be L. nucran- 

 tluts has pale colored seeds, and is similar to my plant in other 

 respects. Under the circumstances, I do not care to offer a name 

 for my collection at the present time. 



Ltjpinus polycarpUvS Greene, Pittonia 1: 171. 1888. 



This robust plant with "short narrow close racemes of small 

 flowers and many large pods," as characterized by Jepson, is cer- 

 tainly a well-marked form, at least as compared with its rela- 

 tives of middle western California. It is anything but conspic- 

 uous when in bloom, especially if growing amid grass, while L. 

 vallicola apricus is almost, if not quite, as showy as L. nanus. 

 Poly carpus in fruit, however, is as noticable as any, if not the 

 most conspicuous of them all. About Stanford University, at 

 least, it seems to prefer adobe soil, while L. vallicola apricus 

 grows in sandy loam. 



The following are my collections of L. polycarpus. I noted 

 it also at Santa Rosa, Guerneville, and Sebastapol, Sonoma 

 county: 



Hall's valley, Mt. Hamilton range, 10 May, 1907, 129/; 

 Mayfield, Santa Clara county, 22 March, 1908, ij6j, 13 April, 

 1908, 1396; Petaluma, Sonoma county, 1 April, 1908, /J/9, 

 1383; Stanford University, Santa Clara county, 22 April, 1908, 

 1409. 



In conclusion, I would thank Professors Dudley and Abratns 

 for many courtesies extended to me in connection with the her- 

 barium and library of their department at Stanford University. 

 Many helpful suggestions were also freely given me by them, 

 altho the work was not done under their direction. To Dr. 

 Hall I am duly grateful for the privilege of examining the lu- 

 pine series in the herbarium of the University of California. 

 To Mr. Heller I also extend my thanks for the use of specimens 

 of his numbers 7850 and 10100.
