This species has nearly upright leaves with narrow lobes which 
droop at the tips, and slender stalks which are slightly prickly, the 
prickles very short. We have only small specimens of it 
Garden as yet, raised from seeds obtained from a Californian 
nursery. 
In 1883 (Garten Zeitung, 2: 198) Wendland described a second 
species of the genus under the name IV’ashingtonia robusta, from 
plants sent him by Van Houtte, of Ghent, which he says origi- 
to the north; this species is much more fully described by Andre 
in Revue Horticole, 57: 401-404, 1885, where it is also illus- 
trated. It has spreading darker green leaves than the one first 
known, their stouter stalks armed with stout curved yellow 
prickles often half an inch long, the lobes of the leaves rela- 
tively broader and less abundantly provided with the character- 
istic fibrils which resemble those of palmettos (/zodes), It was 
almost certainly derived from southern California, where it grows 
eee in isolated oases in the desert in San Diego County. A 
these palm oases taken from a photograph secured 
Sy Dr. MacDougal and Mr. Coville while studying the best local- 
ity for establishing the Desert Laboratory of the Carnegie Insti- 
tution is shown on the accompanying plate (Plate XX.); the trees 
are about fifty feet high, and their old leaves remain attached to 
the trunk for several years after wilting. The Garden has re- 
cently received as a gift from Mr. C. M. Hyde a very fine pair 
of these palms, with trunks about seven feet high and leaves four 
feet in diameter ; they are exhibited in the central house of the 
public conservatories, and are represented on the accompanying 
plate made from a photograph (Plate X XI.). 
This IT ashingtonia robusta of Wendland is the same plant as the 
specimen figured by Sargent in Silva of North America, 10: 47, 
plate 509, as IV. filamentosa. As yet there is no certain ae 
that the original 7 filamentosa occurs wild within the United 
States, though Watson remarks (Proc. Amer. Acad. 25: 137) 
that it probably exists in the mountains bordering the Colorado 
River north of the Mexican boundary.
