The latter is confined to the region north of Tehachipi where M. 

 exile which is spreading as a weed overlaps it. The two species 

 are in habit and flower extremely unlike, and the carpels though 

 similar can be readily distinguished; those of M. exile forming 

 an incomplete, and those of M. Parry i z. complete circle. 



Miaomeria purpurea Kelt* is erroneously referred to Mentha 

 Pulegium; it is a synonym of M. Canadense. 



Convovulus luteolus var. Solanesis appears to be the same as 

 C. fruticetorum Greene. 



Thelypodium Greeni is a new name for the T. flavescens of Prof. 

 Greene's Manual which was by Watson 5 reduced to Caulautlius 

 procerus. Dr. Jepson considers them the same species, and the 

 new name would seem to be unnecessary. 



Dtaba {Heterodraba) unilateralis is united with Athysanus as 

 a second species — where it is not very well placed. 



Helianthella castanea. Of this species the author remarks: 

 "Fruiting heads not seen by us." I collected it at Laundry 

 Farm a few miles from Berkeley, May 29, 1892, and considered 

 it a hybrid of Wyethia angustifolia and H. Californica. A more 

 recently described species, H. Cannonce, has perhaps a similar 

 origin with one different parent. 



Senecio Greenei. "Mountain side near the Geysers, growing 

 under bushes of Pickeringia and Ceanothus, E. L. Greene, 

 June 17, 1874. Collected since only on Mt. Sanhedrin, Mendo- 

 cino Co., Rattan" has been brought thence by nearly every 

 collector who has visited Lake County. 



Microseris macrochatta, taken up under Uropappus, has been 

 shown to be an immature state of one of the other species prob- 

 ably M. lineari/blia 6 while M. Kelloggii given as a variety of M. 

 macroctuzta belongs without doubt under M. Lindleyi. M. Cleve- 

 landi placed as a variety under M. Lindleyi is the prevailing 

 southern form of that species and is identical with M. Parryi (an 

 older name ) a fragment of the type of which I have seen
