Genus HELENIUM Linnaeus. 
HELENIUM BIGELOVII A. Gray. 
HELEIUM PUBERULUM DC. 
Helenium puberulum DC.—This plant 
is common along water courses from 
San Francisco southward to Santo 
Tomas, Baia California. Bancroft 
says this plant is used by the Indians 
in the same way as we make use of 
sarsaparailla. Mrs. Bingham (1. .c.) 
says it is “used as a tonic and antis- 
corbutic, and also in the form of a 
powder for catarrh.’’ She gives’ the 
vernacular name ag sneezewood. It is 
known to the Mexicans as rosea or 
rosilla (the proper spelling of the word) 
who inform me that the seed is the part 
mainly used medicinally. 
Genus SYNTRICHOPAPPUS A. Gray. 
SYNTRICHOPAPPUS FREMONTI A. G. 
Genus GRINDELIA Willd. 
GRINDELIA ROBUSTA Nutt. 
Grindelia robusta Nuttall.—This is a 
popular remedy, especially recommend- 
ed as a remedy for the effects of the 
poison oak (Rhus diversiloba Torr. & 
Gray), the plant being applied fresh, or 
a decoction or alcholic infusion used 
(Mrs. Bingham). The crude drug sells 
at about $5.00 per hundred pounds. A 
Russian scientist is at present engaged 
in a study of the medicinal properties 
of this plant and of the other species 
of the genus—most of which seem to 
possess the same valuble_ properties 
and some of which are doubtless often 
substituted for or confused with the 
typical G. robusta of Nuttall. One of 
these, G. subsquarrosa, I have recent- 
ly supplied to an eastern firm, send- 
ing them about fifty pounds of the 
crude drug, for them to thoroughly 
test its properties.

PHANTACH@MTA PALHACHA Greene, 
“A span high, with very numerous fili-

corollas of ray and disk y.: akenes nearly 
l near; pappus-bristles 5, slender, with a 
thin, triangular palea at base.’’—Greene,
