secured it on Parker Mountain, in the same county, no. 3237. It seems to be 
alpine, coming in just at timberline, among the straggling, dwarfed, depressed 
remnants of the forest and persisting for some hundreds of feet higher. 
HAPLOPAPPUS EXIMIUS Hall, Univ. Cal. Publ. 6:170. 1915.—It 
is refreshing to see technical papers so fully and painstakingly 
worked out as those by Professor H. M. Hatt. He is so evidently 
fair that his arguments are unusually convincing. Nevertheless, 
in publishing this species he states so fully the differences that 
separate the Haplopappus segregates as to confirm (rather than 
otherwise) their validity. Those who take this view will think, 
therefore, that the name of the above plant should be Tonestus 
eximius, n. n.

1916 we noted the salient characteristics of C. miniata and its var. 
crispula (Piper) Nels. and Macbr. Recently our attention has 
been called to another variation by specimens sent us from Alberni, 
Vancouver Island, by Professor J. K. Henry (his no. 9070 in the 
Gray Herbarium). These differ from typical material of C. 
miniata only in the very thick leaves. This maritime plant has 
been designated C. Dixonii (loc. cit.), the type being composed of 
decumbent or only slightly ascending plants that evidently repre- 
sent the extreme condition of this variation. Piper 4957 from 
Ilwaco, Washington, is, like the Henry specimens, erect or nearly so. 
The coastal plants, therefore, seem to represent merely an ecological 
state of typical C. miniata, and may be treated varietally.
