My thanks are due to the following gentlemen, who have 

 generously granted me the privilege of examining certain spe- 

 cies of the section Platycarpos: Dr. E. L. Greene; Mr. S. B. Par- 

 ish; Dr. J. N. Rose, of the U. S. National Museum; Dr. Wm. 

 Trelease, of the Missouri Botanical Garden; Professor Aven Nel- 

 son, of the University of Wyoming; Professor L. R. Abrams, of 

 Stanford University, and Dr. H. M. Hall, of the University of 

 California. 



LUPINELLUS 



Annual: flowers axillary, solitary, keel nearly straight: pods 

 ovate, 2-seeded. 



Lupinus uncialis Wats. Hot. King Rep. 54.//- 7. f. 5-10. 1871. 



"Annual, dwarf, villous, diffusely branched, leafy; leaflets 

 5, oblong-spatulate, obtuse; flowers small, axillary, solitary; the 

 peduncles equaling the leaves or shorter; legumes 2-seeded. — 

 Very small, but 1 inch high; leaves on %- l / 2 inch petioles, leaf- 

 lets 2 lines long; stipules adnate, obtuse; bracts short, oval; the 

 upper lip of the calyx deeply 2-cleft, the lower larger, 3-toothed, 

 the middle tooth small; vexillum obovate, shorter than the wings 

 and keel, the sides scarcely at all reflexed; wings free or but 

 slightly united; keel rather obtuse; flowers ochroleucous, the 

 keel tipped with purple. Found on the dry foot-hills of the 

 Truckee and Pah-Ute Ranges, Western Nevada; 5,000 feet alti- 

 tude; May, June. Plate VII. Fig. 5. An entire plant; twice 

 the natural size. Fig. 6. A flower. Fig. 7. Calyx opened out. 

 Fig. 8. The petals. Fig. 9. The stamineal column, opened. 

 Fig. 10. Ovary; all enlarged four diameters. (224.)" 



To the best of my knowledge this species has never been 

 found since Watson collected it in 1868. It is evidently a plant 

 of rather restricted range, as indeed are many of the lupine spe- 

 cies, and that it has not been encountered again is probably due 

 to the fact that no botanist has visited the region where il was 

 originallv collected. In the Botany of California the type local- 

 ity is more definitely stated as "on rocky hillsides near the Big 

 Bend of the Truckee in North western Nevada/"
