VOL. Iv.| Writings of Edward L. Greene. 93 
Laphamia Peninsularis Greene * is Perityle Fitchii Gray. 
Senecio Blochmane Greene is S. Douglasii DC. 
Prenanthes stricta Greene is Luina Piper? Rob. Mr. 
Greene’s name is the earlier, but it is a curious commentary 
on his attempt to separate the Cichoriacexe as a distinct order 
from the other Compositze 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 +} Greene seems to be only the inland 
form of JZ. saxatilis 'T. & G. A specimen collected on the 
Santa Lucia mountains and referred by Mr. Greene to JZ. altis- 
sima is certainly nothing but saxafilis. The type is from 
Tehachapi, and was collected:by the writer. 
Malacothrix insularist & squalida§ Greene and M. foliosa 
Gray are forms of the same species. 
Stephanomeria virgata Benth. S. paniculata & exigua Nutt. 
S. coronaria || & tomentosa | Greene and ‘‘ Ptiloria’’ canescens 
& pleurocarpa Greene, represent at the utmost three species, and 
they are so difficult to discriminate and so entangled with con- 
necting forms that they may have to be reduced to one. 
Lobelia Rothrockit Greene is the variety serrata of Palmerella 
debilis Gray. 
Downingia concolor,** humilis, insignis, montana, 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. 
Howellia limosa Greene is extremely like the terrestrial form 
of H. aquatilis Gray. The chief difference seems to be in the
