jave desert, growing on a low gravelly ridge, and rather abund- 

 ant. This has been confused by some with T. gracilifiora^ but 

 the two are not at all alike, this species having very small flow- 

 ers. It was "collected in Arizona by Dr. Edward Palmer."

No. 7888, collected May 29, at the river bridge near Red- 

 ding, in sand. These plants do not seem to differ from speci- 

 mens from the sand hills at San Francisco and Bodega bay. 

 ►S. strigulosum to which no more definite locality is assigned 

 than "Nova California," does not seem to be distinct from S. 

 contortum,^ the type of which came from "sandy barren soil, on 

 the interior banks of the Columbia River." 



Sphaerostigma campestre (Greene) Small, Bull. Torn Club,

Oenothera cafnpestris Greene, Fl. Fran. 216. 1891. 



No. 7590, collected April 5, on sandy plains at Oil City 

 near Bakersfield, Kern county. Neither of the three numbers 

 collected are "more or less hirsute-pubescent throughout," but 

 are glabrous except for some short hairs on the leaves and ex- 

 treme upper part of the stem; neither do the flowers turn "brick- 

 red," at least not when drying, and the writer has no recollec- 

 tion of seeing the changing color in the field. The petals are 

 bright yellow, broadly obvovate orbicular, 8 mm. long, 10 mm. 

 wide, with two rows of small red dots in the throat The very 

 narrow leaves are distantly dentate with inconspicuous teeth.
