30 Historical Sketch of the Science of Botany | [January, — 
Charles Wright spent several years in Texas, the botany of — 
which country he studied. Then, in 1849, he went westward to 
El. Paso, in New Mexico. His rich collections of plants were ~ 
placed in the hands of Prof. Gray, who described and published | 
“Plante Wrightiane” in the third volume of Smithsonian Con- © 
tributions, with ten plates. In 1851-1852, he was again in New 
Mexico, the collection of which tour -furnished the material to — 
the second part of Plante Wrightianz, with four plates, in the — 
fifth volume of the Smithsonian Contributions. | 
Another well-known botanist explored New Mexico at the © 
same time. August Fendler came, about the year 1836, from — 
Germany to North America. In 1846 he left Fort Leavenworth — 
with a military train, followed the Arkansas river up to Fort — 
Bent, crossed the mountains to Santa Fé, where he made his — 
principal collections from April to August, 1847. An account of — 
his collection Prof. Gray published in the Memoirs of the Ameri- — 
can Academy, Vol. iv, under the title, Plantae Fendlerianz. Fend- — 
ler resided a long time near St. Louis; went afterwards to Vene- — 
zuela, and is now collecting on the Island of Trinidad. ; 
Dr. Woodhouse was a member of the expedition down the — 
Zui and Colorado rivers under the command of Capt. Sitgreaves, — 
in 1850. His collections, placed for examination in the hands — 
` of Prof. Torrey, consist of three portions: the first, collected — 
between Neosho and Arkansas rivers, and on the north fork of © 
the Canadian, and the second, from Texas, contain nothing new. | 
The plants of the third portion were collected in Arizona and — 
California. The catalogue of the latter (about 180 species) is 
published with twenty-one plates, in 1853, with Sitgreaves’ Re- 
port. There is described a new genus of the order of Amaran: 
tacez and several new species. a 
-In the year 1852 an expedition under the command of Capt 
- Marcy explored the Red river to its sources. The botanical col- 
lection of 200 species, made by Dr. Shumard, was examined by — 
Prof. Torrey. and published in App. G of Marcy’s Report “ig 
twenty plates. 
The botany of these formerly Mexican provinces was nearly un- 
known before Berlandier ; but by the collections of the above-named — 
botanists much light was thrown upon it; their work was further 
advanced by the Pacific railroad explorations and the Mexican 
boundary survey, and will be completed by the surveys of the
