shorter than the leaves. “Fhe pods are chartaceous and globose, 
this is my var. ovalis. As we go into southern Utah in the Tropi- 
cal life zone where it is much hotter.we find the diphysus forms 
with thin pods with a tendency to being narrower and intergard- 
ing with the remarkably narrow linear pods of what I once called 
A. palans and later put as a var. of lentiginosus. When we get 
into the Lahontan basin commonly known as the Carson sink and 
its adjacent low areas that run from southern Oregon along the 
eastern base of the Sierras to beyond Walker lake we find the thin 
podded diphysus forms on the mesas, the ovalis forms in the can- 
ons and another prostrate papery podded form along the alkaline 
places in the valleys, all apparently intergarding. On the higher 
mountains westward we find the closely related A. Bolanderi with 
stipitate pods whose genetic ne the writer has not yet 
made out, but which is also related to the arrectus group through 
A. Weiserensis. When we get on in Death valley slope and par- 
ticularly in the Owen’s valley region and Mojave desert and south- 
ward we find other variations, due to the intense heat and greater 
aridity, to protect the plants from radiation. The prostrate forms 
are absent except the var. aridus. The ae are mostly chartace- 
ous but when glabrous are papery mostly. e flowers are often 
very dark-purple while they are normally toh. colored; and two 
orms occur, one with the normal sized ones and one with very 
small flowers but intergarding. There are two forms as to length 
of racemes, one has long ones and very conspicuous, the other 
has short ones and condensed, this latter mostly with smooth pods. 
The long racemes have two forms one with smooth pods-and 
one with almost woolly nate this is the var. Fremonti. In nearly 
When we get into the Needles region along the Colorado river 
these forms are nearly all absent and are replaced by robust forms 
with large smooth and papery pods in dense racemes. Now to 
recognize all these multitudes of forms as species will finally land 
us where Greene and his five hundred species of Eschscholtzia are, 
chaos. To consider them all as variations, due to climate an 
soil, of one polymorphous species makes of them the most interest- 
ing and instructive studv in ecology and in addition keeps them 
all together where they belong, and does not confuse either the 
novice or the expert. This is the writer’s view of the way other 
species should be treated, and it removes the temptation from sel-
