Cardamine multifolia sp. nov. 



Stem about 2 dm. high, very leafy, lower part hirsute : leaves 

 4-6 cm. long glabrous; leaflets 7-13. oblong to oblong-obovate 

 or oval, entire or sinuate-dentate ; the terminal one larger and 

 obovate : flowers numerous : petals spatulate, about 2.5 mm. long ; 

 pedicels ascending, about 8 mm. long : pod erect, about 2 cm. 

 long and .75 mm. wide. 



This is perhaps closest related to A. parvifolia L., but is more 

 leafy, has shorter and broader leaf-segments and erect pods, and 

 the plant is less diffusely branched.

The plant described by Dr. Watson in the Botany of California 

 and by Dr. Robinson in the Synoptical Flora (p. 139) is I think 

 without doubt the var. brevipes of Torrey and Gray's flora. Prob- 

 ably also Bourgeau's plant, cited by Fournier, belongs here ; but I 

 think that it is very doubtful that Hartweg's plant, which must be 

 regarded as the type of 5. Harttvegianiim Fourn., could be the same. 



Sophia Calif ornica (T. & G.) 



Sisymbrium canescens e (Ca/iforuieum) T. & G. Fl. N. Am. i : 

 92. 1838. 



This species is characterized by the large flowers, the sparingly 

 stellate and often glandular-puberulent stem, the uniserial linear 

 pod and once or twice pinnatifid leaves. The segments of the 

 lower leaves are broad and obtuse, those of the upper linear to 

 oblong. Its range extends from Montana to Washington south to 

 California. 



Sophia viscosa sp. nov. 



Biennial, 5-10 dm. high : stem, at least the upper part, decidedly 

 glandular or viscid-villous : leaves obovate or oblanceolate in out-
