DIEGO DEL CASTILLO, JUAN CERDA, D. VINCENTE CERVANTES and D. MARIANO 
Mocıno. Mocıno explored the coasts of Tabasco and Guatemala and later 
the region inhabited by. the Tarahumaras. During the years 1795 to 1804, the 
work of the scientific commission was most actively prosecuted’ The fruits of 
the conjoint labors of the members of the commission were a good herbarium 
and a work in manuscript entitled Flora Mexicana. With a rich herbarium, 
an excellent collection of 1400 colored drawings the work of ECHEVARRIA and 
CERDA and with their previous manuscript SESSE and MoCıno departed for 
Spain with the idea of publishing the results of the expedition. Delays, fatal 
to the enterprise, discouraged the hopes of Mogino and Sesse, and it was not 
until long after their death in 1888 that the flora appeared as a publication 
of the Mexican Society of Natural History, as “Flora Mexicana Autoribus 
Martinus Sesse et Josephus Marianus Mogino”. 
ALEXANDER VON HUMBOLDT and AımE BONPLAND passed nearly a year in 
the exploration of Mexico, debarking at Acapulco on March 13, 1803, visited 
the United States and returned to Europe in July 1804 with rich collections 
of plants, animals and minerals. BONPLAND was the virtual botanist of the 
expedition and he collected 6,000 species of plants which are preserved in the 
Museum of Natural History at Paris. He published Nova Genera et Species 
Plantarum (7 volumes, folio with 700 plates, ı815) and Equinoctial Plants 
collected in Mexico, Cuba, etc. (2 vols. folio 140 plates). 
 Passing over the names of TATE, LEXARZA, SARTORIUS and KARWINSKI, 
we come to that of Jomn Louis BERLANDIER, who collected in Tamaulipas, 
San Luis Potosi, Nuevo Leon and Coahuila during the years 1827—30. Part 
of his collections is in the Kew Herbarium. SCHIEDE and DEPPE visited Mexico 
about 1828 and collected near Jalapa, Orizaba and Cuernavaca. The results 
of their labors and those of HEGEWISCH and MUEHLENPFORDT were contributed 
to Linnaea by SCHLECHTENDAHL and CHAMIsso. H.M. S. "Blossom” touched 
at Mexico in ı828 and Mr. LAY explored Tepic and Jalisco. HOooKer’s herbar- 
ium, DELESSERT’s herbarium and that of Kew contain the specimens collected 
by this expedition. THOMAS COULTER collected in Mexico for many years., 
uring 1832 and 1833, he explored Alta California and Sonora. His collec- 
tions were deposited in the herbarium of Trinity College, Dublin, where they 
were studied by W. H. HarvEy. G. ANDRIEUX, who visited Mexico for plants, 
sent his collections to DELESSERT, HOOKER and DE CANDOLLE. HENRY 
ALEOTTI, AUGUST B. GHIESBREGHT, JOHN J. LINDEN and NICHOLAS .- 
extensively explored Mexico during the years 183640 and made UBE BER 
lections of plants. They ascended the peak of Orizaba, and Galeotti ge 
Popocatepetl, reaching the limit of vegetation at an elevation of 10,500 eet. 
eir plants were distributed to several of the large Europem herbaria. 
THEODORE HARTWEG was sent by the Horticultural Society of pi 
to Mexico in ı8 36 with the object of collecting living plants and Br 
&plored the mountains at Guanajuato, Leon, Lagos, Guadalajara, 
Calientes, Morelia and Oaxaca and left Mexico in 1839 for Guatemala. His
