observation will show that this character pertains to the whole Of 



genus. A. longifiora is readily distinguished from the other '^GVV 

 acaulescent species by its smoothness and practically entire 

 leaves. 



Sphaerostigma contortum (Dougl.) Walp. 



No. 8288, collected May 18, in coarse granite sand in the 

 Sierra foothills west of Bishop, Inyo county. The pods in these 

 specimens are sessile, hardly contorted, either straight or a little 

 curved, ascending, about 2 cm. long, not narrowed at the apex. 

 Perhaps a distinct species. 



Sphaerostigma hirtellum (Greene) Small, Bull. Torr. Club, 

 33: 190. 1896. 



Oenothera hirtella Greene, Fl. Fran. 215. 1891. 



No. 8166, collected April 12, in Madera county on gravelly 

 hillsides along the San Joaquin river about five miles above Pol- 

 lasky. The given range is "common in the hill country away 

 from the .sea, from Lake Co. and Solano southward." Our 

 plant has a smooth stem, all the pods except the lowermost 

 glabrous, and the leaves narrower than the type. Probably un- 

 described, but referred here for the present. 



Sphaerostigma boothii (Dougl.) Walp. Rep. 2: 77. 1843. 



Oenothera Boothii Dougl.; Lehm. in Hook. Fl. Bor. Am. 

 1:213. 1833. 



Oenothera pygmaea Dougl. 1. c. 



Oenothera lithospermoides Nutt.; Wats. Proc. Am. Acad. 

 8: 604. 1873. 



No. 8238, collected May 11, along the base of the White 

 mountains opposite Laws, Inyo county, in gravel and sand. 

 The capsules are immature and are not much enlarged at base, 

 so it is referred here with some doubt. The type was collected 

 "on low exposed gravelly hills, near the branches of Lewis and 

 Clark's River, lat. 46 degrees north."
