98 Writings of Edward L. Greene. [ZOE 
Californica Benth.—the latter itself considered by Dr. Gray only 
a form of SS. du//ata Benth. 
Chorizanthe Nortont Greene is a variety of C. Douglasit 
Benth. 
Ertogonum grande & rubescens Greene are mere variations of 
£. nudum Dougl. 
Eriogonum molle Greene described as ‘‘not in flower” has 
since been collected in better specimens and proves to be £. 
giganteum Wats. 
Eriogonum robustum Greene* is the form of £. Loddzt growing 
at lower elevation. The type of 4. vobustum, collected by the 
writer, was found at about 4,500 feet. 
Eriogonum elegans Greene is one of the forms of either Z. 
gracile Benth. or £. Baileyi Wats. LE. Baileyi as everyone 
knows was formerly termed ‘‘ 2. gracile var. effusum,’’ and 
there are numerous forms now known which can be referred 
equally well to either. Mr. Greene’s reason for comparing it to 
the suffrutescent £. saxati/e cannot be conjectured. 
Eriogonum agninum Greene judging from the imperfect 
character is Z. gracile var. leucocladon (£. leucocladon Benth.). 
Eriogonum Davidsonit Greene Pitt. ii, 295 was reduced by 
the author in ‘“‘Errata’”’ a few pages further on in the line 
‘« Eviogonum Davidsonti=E. molestum Wats.” 
Eriogonum taxifolium Greene has by other botanists always 
been considered a form of 2. Wrighitzt Torr. 
Plerostegia galioidest Greene is P. macroptera Benth. 
Plerostegia fruticosat Greene (Harfordia fruticosa,t Greene & 
Parry) is apparently only an insular variety of the same. 
Atriplex dilatata Greene is A. Barclayana (Benth.) 
Atriplex nodosa Greene is A. expansa Wats. It was described 
from a single old and fragmentary specimen collected by the 
writer. A. expansa often shows two strikingly different forms 
of fruit in the same plant. 
Amarantus carneus Greene is probably an introduced weed. 
It may be 4. polygonoides I,., though from the very imperfect
