CONTRIBUTIONS FROM THE GRAY HERBARIUM OF HARVARD 
UNIVERSITY. — NEW SERIES, No. LIII 
I. NEW OR OTHERWISE INTERESTING PLANTS, 
MOSTLY NORTH AMERICAN LILIACEAE 
AND CHENOPODIACEAE 
By J. Francis MacsripE 
Durinc the past year I have had the pleasure of studying various 
collections, mostly from western North America, which have been 
sent to the Gray Herbarium for determination. In the course of 
work of this nature one invariably discovers instances where 
species have been known under names no longer tenable in accord 
with those principles of nomenclature expressed in the Interna- 
tional Rules. Also, especially in the case of collections from 
portions of the western United States where the flora is even yet 
imperfectly known, species apparently undescribed have from 
time to time come to light. Two collections have been particularly 
noteworthy in this respect. One was made by Mrs. Mary F. 
Spencer of San Diego and consists of some three hundred species 
largely from the Mohave and Colorado Deserts, regions long 
known as possessing a unique and interesting flora. Mrs. Spencer 
secured, in most instances, four duplicates of each species collected. 
The other collection was made by Mr. J. C. Nelson, principal of 
the high school at Salem, Oregon. Mr. Nelson, accompanied by 
Professor Peck of Willamette University, was able in late June to 
make a hurried trip to Curry Co., Oregon, a region which appar- 
ently has never been botanized. He found a number of species 
which are rare, at least in southwestern Oregon, several represent- 
ing range extensions from California. Notable in this last respect 
was the discovery of Zauschneria californica. 
The following pages, therefore, have resulted partly from deter- 
minative work as outlined above but the notes on the Liliaceae 
and the Chenopodiaceae have arisen from an attempt to order up, 
in accord with recent literature on the groups, certain material 
already in the herbarium. My observations on the Chenopodiaceae
