Laphamia Peyiinsidaris Greene * is Perityle Fitchii Gray. 



Senecio BlochmancB Greene is ^S". Doiiglasii DC. 



Prenanthes strida Greene is Luina Piperi Rob. Mr. 

 Greene's name is the earlier, but it is a curious commentary 

 on his attempt to separate the Cichoriaceae as a distinct order 

 from the other Compositae that he should have referred a Senecio 

 to Prenanthes. His latest attempt to settle its relationship is to put 

 it into Cassini's " Psacalium," but as Psacalium is always reduced 

 to Cacalia and Cacalia usually to Senecio he might as well have 

 reduced it to that genus at once. 



Malacothrix altissima f Greene seems to be only the inland 

 form of M. saxatilis T. &. G. A specimen collected on the 

 Santa lyucia mountains and referred by Mr. Greene to M. altis- 

 sima is certainly nothing but saxatilis. The type is from 

 Tehachapi, and was collected by the writer. 



Malacothrix insularisX & sqiialida^ Greene and M. foliosa 

 •Gray are forms of the same species. 



Stephanomeria virgata Benth. .S. paniculata & exigua Nutt- 

 6*. coro7iaria\\ & tomeritosa*^ Greene and '' Ptiloria^^ canescens 

 & pleiirocarpa Greene, represent at the utmost three species, and 

 they are so difl&cult to discriminate and so entangled with con- 

 necting forms that they may have to be reduced to one. 



Lobelia Rothrockii Greene is the variety serrata of Palmerella 

 debilis Gray. 



Doiuningia co7icolor,'^^ humilis, insigJiis, vionta7ia, ornatis- 

 sima & tricolor Greene are forms of a single polymorphous 

 species. Three or four of them can often be collected in the 

 same "hog-wallow." At Vanden Station, for instance, in the 

 same late-dried depression, the writer collected D. pulchella^ D. 

 ornatissima, D. concolor & D. humilis, 



Hozvellia limosa Greene is extremely like the terrestrial form 

 of H. aquatilis Gray. The chief difference seems to be in the
