to Colonel Graham’s party, he returned with him without 
reaching farther westward than about the middle of what is 
now the territory of Arizona, and in the summer of 1852 he 
returned with his extensive collections to San Antonio, and 
thence to St. Louis, to deliver his Cactacee to Dr. Engelmann, 
and with the remainder to Cambridge. . These collections 
were the basis of the second part of “ Plante Wrightianz,” 
published in 1858, and, in connection with those of Dr. Parry, 
Professor Thurber, and Dr. J. M. Bigelow, ete., of the Botany 
of the Mexican Boundary Survey, published in 1859. As 
Mr. Wright collected more largely than his associate botanists, 
and divided his collections into sets, his specimens are incor- 
porated into a considerable number of herbaria, at home and 
abroad, and are the types of many new species and genera. 
No name is more largely commemorated in the botany of 
Texas, New Mexico, and Arizona than that of Charles Wright. 
It is an Acanthaceous genus of this district, of his own dis- 
covery, that bears the name of Carlowrightia. Surely no 
botanist ever better earned such scientific remembrance by 
entire devotion, acute observation, severe exertion, and perse- 
verance under hardship and privation. 
Mr. Wright’s next expedition was made under more pleas- 
ant conditions. It was a long one around the world, as bot- 
anist to the North Pacific Exploring Expedition, fitted out 
under Captain Ringgold, who was during the cruise succeeded 
by Commander John Rodgers. After passing the winter of 
1852-3 at his home in Connecticut and at Cambridge, he 
joined this expedition in the spring, and sailed in the United 
States ship ‘“‘ Vincennes ” from Norfolk, Virginia, on the 11th 
of June. The collections made when touching at Madeira and 
Cape Verde were of course unimportant; but at Simon’s Bay, 
just round the Cape of Good Hope, a stay of six weeks re- 
sulted in a very considerable collection of about 800 species 
within a small area, the Cape being wonderfully crowded 
with all kinds of plants. The voyage was thence to Sydney 
and through the Coral Sea to Hongkong, which was reached 
about the middle of March, 1854. The collection of over 500 
species of Phenogamous plants, which was made during that
