authoritive handbook on the flora of the Rocky Mountain Region, his prelimi- 
nary work appearing as Flora of Colorado (1906). 
The Great Basin Region has been mentioned incidentally in the accounts 
of the exploration of the west and the Rocky Mountain Region. One of the 
first reports on the Great Basin proper was printed at Philadelphia in 1852. 
It is an account by HOWARD STANSBURY of the exploration and surveys of 
the valley of the Great Salt Lake, which includes a catalogue and description 
of plants by JoHN TORREY. Torrey also elaborated the catalogue of plants 
collected by Captain L. SITGREAVES on an expedition down the Zuni and 
Colorado rivers about 1854. DURAND later in 1860 contributes to the Trans- 
actions of the American Philosophical Society descriptions of the species 
constituting the flora of the Great Salt Lake Basin and Drs. GRAY, TORREY, 
THURBER and ENGELMANN, a botanic report on the expedition of Lieut. J. C. 
FREMONT in 1857—58 to the Colorado River of the West. A Catalogue of 
Plants collected in 1872 in Utah, Wyoming, etc. by J. M. COULTER is the 
title of a paper published by the U. S. Geological Survey of Montana, Idaho, 
Wyoming and Utah in 1873. 
The work, however, which may be said to represent the flora of the region 
in the most comprehensive manner is the Botany of the Fortieth Parallel, 
Washington 1871, by SERENO WATSON and D. C. EAToN. Several other works 
must be mentioned dealing with the flora of the arid region in completing 
this general survey, viz., Report of Explorations across the Great Basin of the 
Territory of Utah by J. H. Smpson 1876; Catalogue of Plants collected in 
Nevada, Utah, Colorado, New Mexico and Arizona, as volume V of the reports 
on U. 5. Geological Survey west of the One Hundredth Meridian, (Lieut. 
WHEELER in charge) by J. T. ROTHROCK, Washington 1878 and. CoVILLE’s 
Botany of the Death Valley Expedition 1893, issued as volume IV of Con- 
tributions from the United States National Herbarium. 
VI. Pacific Coast. 
The finely equipped scientific expedition of La PEROUSE left France in 
1785. On September ı4th, 1786 the ship anchored in Monterey Bay where 
the botanists of the expedition MARTINIERE and COLLIGNON took advantage 
of the stop to collect California plants’). The first one described by LAMARCK 
was Adronia umbellata secured by Collignon. The next botanists to visit Cali- 
fornia were THADDEUS HAENKE and LuIs NEE who accompanied the Spanish 
expedition under MALASPINA, which touched the coast at San Diego and 
Monterey in 1791. Between ı789 und ı817 HAENKE botanized along the 
western side of the American continent from Patagonia to Bering Strait. His 
collections are in part at Prague and were described by PrEsL in Reliquiae 
and part in the herbarium of the Royal Garden at Madrid. Through a con- 
fusion of labels, some of his plants described as Chilian were probably col-
