CALIFOBNIAN FIELD NOTES. 1*^9 



Lepidium diciyoium, Gray, var. acutidens, Gray. ^ Common 

 on the desert near Lancaster. In some of the specimens, the 

 stigma was quite prominent. 



Lepidium niiidum, Nutt. The southern type o£ this species 

 is one of the common weeds of early spring, and when robust 

 is hirsutulous, not only on the branches, but also on the mid- 

 rib and edges of the leaves. The petals are always present 

 and the flowers are all fertile ; the stamens sometimes ap- 

 parently two through union of the filaments. A few plants 

 of what I presume is the northern form I found by a road- 

 side near the city, though growing luxuriantly, they were 

 more glabrous than the native species: the petals were absent, 

 the pod had a narrower cleft, and the pedicels were more 



decurved. 

 Lepidium lasiocarpum, Nutt. Azusa.
