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 Cactacece to Dr. Engelmann, 

 and with the remainder to Cambridge. These collections 

 were the basis of the second part of " Plantae Wrightianae," 

 published in 1853, and, in connection with those of Dr. Parry, 

 Professor Thurber, and Dr. J. M. Bigelow, etc., 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 Phsenogamous plants, which was made during that
