Without locality, Avvendberg, No. 376a (hb. Gr.). This species 
has its affinity with 4. msgind@folium, Gray, E. chapalense, Wat- 
son, and &. campylocladum, Robinson, but is amply distinct from 
allof them. ‘The unequal setz of the pappus is rather an excep- 
tional trait in the genus, nevertheless all the other essential 
characters are in common with typical Aupatorium. 
PALMS OF BAJA CALIFORNIA. 
BY T. S. BRANDEGEE. 
Washingtonia filifera, W. Sonora, Erythea armata and £.. 
edulis are grown in the gardens about San Diego, and a few young 
plants of EArythea Brandegei are established. The seeds of £. 
Brandegez have been extensively planted in Southern California 
recently, and it seems as if this palm should grow well in its new 
habitat, for it will not experience as much frost and ice as it does 
on its native mountains. 
Wendland based the genus Washingtonia upon a palm pre- 
viously known as Brahea filifera. W.vrobusta was later added to 
the genus, but is by many considered to be doubtfully distinct, 
and there seems to be a good deal of uncertainty concerning both 
these species. In Botanische Zeitung, 37, 1878, Wendland 
describes the genus Washingtonia and writes that credit is due to 
Herr J. Linden of Ghent for the first importation, perhaps in the 
year 1869—at the time of this description seed collected a few 
years after 1870 in Cantillas Cafion had been distributed. One of 
the earliest notices of the palms now known as Washingtonia is 
in Botanische Zeitung, 34, where Pritchardia filamentosa is men- 
tioned as a garden name for plants raised in Europe, said to have 
been collected about Arizona and the Colorado River. The 
locality from which the seed came that Wendland examined later 
is not stated.. Under the rule, “once a synonym always a 
synonym,’ the name Washingtonia has been changed to Neo- 
washingtonia, but, in common usage, the new name is disregarded.
