* (Enothera brachycarpa Gray, PI. "Wright, 1, p. 70, and 2, p. 57, was 

 among the interesting plants collected by Miss Searls in the Pahranagat Moun- 

 tains, Nevada. It is the (E. marginata var. purpurea of S. Watson in King's Expe- 

 dition, but is very different from (E. ccespitosa Nutt. (the oldest name of the species 

 which is to comprise CE. marginata, montana, and eximia, doubtless well combined by 

 Mr. Watson), as the fruit demonstrates. The corolla, instead of pale yellow turn- 

 ing rose-color, is now known to be white with a purple tinge from the first.
