390 HARPER: BOTANICAL WORK OF Dr. E. W. HILGARD 
In Garden and Forest for March 7 and June 13, 1888, he had 
short papers on California forest trees; and a longer account of the 
weeds of that state by him appeared in the California Experiment 
Station Report for 1890 (pp. 238-252) and, almost simultaneously, 
in several numbers of Garden and Forest during the second half of 
1891. His paper on the cienagas of southern California, pub- 
lished in the Bulletin of the Geological Society of America in 
1892 and in the California Experiment Station Report for 1892- 
1894, is of some botanical interest, as are several papers on deserts 
and alkali lands in various publications. His review of Fernald’s 
“Soil preferences of alpine plants,’ in Science for January 24, 
1908, shows an intimate knowledge of ecological principles. 
His text-book on Soils, with 620 pages and numerous illus- 
trations, published in 1906, is practically a summary of all his 
researches, and contains much that is of interest and value to 
botanists.* He contributed many papers on cultivated plants 
to the reports and bulletins of the California Experiment Station 
(of which he was director from 1888 to 1904), which it is hardly 
worth while to enumerate separately. 
In the line of botanical discoveries, he is credited by Chapman 
(Fl. So. U. S. ed. 2, 658. 1883) with being the first to find 
Eriocaulon septangulare in the South. During his geographical 
explorations for the ‘‘ Northern Transcontinental Survey ” in 
Montana and Washington in 1882 he collected a few plants, at 
least one of which turned out to be undescribed; this was named 
Oenothera Hilgardi by Greene (Bull. Torrey Club 10: 41. 1883) 
and afterwards transferred to Sphaerostigma by Small (see Piper, 
Contr. U.S. Nat. Herb. 11: 18, 406. 1906). 
The writer, after corresponding with Dr. Hilgard for several

Club 40: 377 et seq. Aug. 1913. ee 
} The plant so determined, if collected on his trip to southeastern Mississipp! 
the spring or early summer of 1859, as seems most likely, may have been another 
ies, perhaps E. lineare Small, which was not distinguished until 1903 (see Bull. 
rrey Club 32: 461-463; 33: 527). For E. seplangulare grows mostly on ane 
shores of lakes and ponds, and blooms in late summer, while E. lineare is a tyP! 
pine-barren plant, and blooms in April and May. The only southern stations ee 
E. septangulare known to the writer are in Lowndes County, Georgia, and Le’ 
Walton and Santa Rosa Counties, Florida. In Small’s Flora it is said to range west 
to Texas, but this statement lacks verification.
