MARCUS E. JONES. 
PEUCEPHYLLUM ScHorri Gray hasasynonym in /zyonia dyso- 
dioides Jones. ‘The writer worked out the proper place of this genus 
in the Composite, and after being unable to match it by any materi- 
al or published species or genus he sent it east for comparison for 
fear that it might prove to be some obscure genus not known to 
him. Receiving a reply that it could not be matched there he 
then ventured to publish it. Mrs. Brandegee, after receiving a 
specimen of it, informed the writer that it matched some material 
of her’s referred to Peucephyllum. A second comparison at Har- 
vard proved that it was identical with Peucephyllum Schottit. Dr. 
Gray having wrongly referred the genus to the Senecionidee 
instead of the 7agetinee, it was not found on the first comparison. 
CHANACTIS MACRANTHA Eaton. The writer had long noticed 
that almost all specimens of the species in herbaria had a wilted 
or collapsed look, and also that growing it never seemed to be in 
good condition. On a recent trip into the desert the writer 
studied the plant growing and found it to be a night bloomer, 
the flowers collapsing early in the morning. A little after sun- 
down the flowers open wide and the outer ones bend over and 
spread out, forming a large head of pearl-white flowers, as the 
pink outer part becomesinvisible then. C. steviotdes seems to be a 
trifle stiffer in the evening, but there is scarcely a perceptible dif- 
ference in the flowers by day or night. All other species of 
Chenactis that the writer knows are day bloomers, or rather, 
keep open all the time. 
GILIA PUNGENS and all its varieties, G. Californica, and G. Wat- 
soni are all night bloomers, nearly all the other species of Gilza
