part of them were left undisturbed, they doubtless still con- 
tinue to grow there, but the place has not been re-visited. 
It was next heard of in 1886, when Mr. John Spence 
collected a few fronds in the high mountain region of Santa 
Barbara County, one of these being brought to the notice of 
Dr. L. G. Yates was identified and recorded by him.! The 
rest are in the herbarium of Prof. Eaton. 
To these stations I am now able to add a fourth, having 
received specimens collected in May of the present year by 
Dr. Anstruther Davidson near Palm Springs, on the 
Colorado Desert. This is the place formerly known as Agua 
Caliente, and is situated at the eastern base of San Jacinto 
Mountain. It has often been visited by other botanists, who 
have brought thence many new or rare plants; but Dr. 
Davidson’s discovery is evidence that it still has rewards for 
a close observer. Dr. Davidson reports it as growing in 
“fair abundance” on the sides of a cafion making up into the 
San Jacinto Mountain. His specimens are larger than those 
heretofore reported, the fronds being from three to six 
inches high. 
It is to be regretted that no particulars are obtainable con- 
cerning the Santa Barbara Station, as it is out of harmony 
with the others both topographically and geographically. 
The others are all in the lower parts of cafions bordering on 
the desert, and it is in similar situations of that arid region 
that future explorations may be expected to add to the 
small number of places in which it has been found, and the 
paucity of its growth indicate, that so far as its North 
American habitat is concerned, it is a species approaching 
its extinction. Beyond our limits it is known only in Chili 
and Bolivia, so that it is one of that small but interesting 
group of plants which connect the North Pacific flora with 
that of the corresponding latitudes south of the equator.
