and 1830, some plants around Buenos Aires (and also in 
to Buenos Aires. visited Porto-Allegro (Brazil) and 
Uruguay, and apparently did little collecting in the Argentine. 
i yen during the voyage of the “ Prinzess Louise . 
(1830-1832) visited South America and botanically explored the 
neighbourhood of Valparaiso and Santiago. He climbed the high 
collections are at Paris and Geneva, and are especially rich in 
‘ompositae. The U.S. Expedition under Capt. C. Wilkes 
(1838-1842) made excursions in the neighbourhood of Valparaiso 
Uruguay, and also south of Buenos Aires, from the Rio Salado 
up to the Serra de Tendil. His plants were sent to Kew between 
1832 and 1849. 
Bacle and his widow sent from time to time various plants 
from Buenos Aires and from the Andes of Argentina to Paris. 
Comte Francis de Castelnau (1845-1847) was in north Chile 
(and also in Colombia, Ecuador, Bolivia and Peru). The results 
of his collecting were published by Weddell, in ‘‘ Chloris andina. 
Essai d’une Flore de la région alpine des Cordilléres de |’ Amér. 
du Sud,”’ Paris, 1855-1857. 
The investigations of J. D. Hooker, as published in his “* Flora 
Antarctica,’’ are very important. Hooker himself visited Her- 
mite Island in the southern part of our region, and his ‘‘ Flora 
Antarctica ’’ includes plants collected by Banks, Darwin, Forster, 
Gaudichaud, King and others. It was believed by Hooker “ that 
successive expeditions have nearly exhausted the phanerogamic 
productions ’’ of the Magellanic area (‘‘ Flora Antarctica,’’ I. 
introd.). me 100 species of flowering plants which were not 
known in 1844 have, however, been discovered there since. 
W. Lechler collected plants in the Magellanic area and in 
Chile. See his ‘‘ Berb. Amer. austr. Accedit enumeratio plan- 
tarum quas in america australi auctor detexit,’’ Stuttgart, 1857. 
William Lobb was a collector for Veitch between 1840 and 
1857. He first visited Brazil, but soon left for Chile, crossing 
the great Pampas of Argentina and the Chilean Andes. Continu- 
ing his journey southwards Lobb penetrated the great Araucaria 
forests, where he collected a large quantity of seeds of Araucaria 
imbricata, and was thus instrumental in bringing this conifer 
into general use for ornamental planting. He returned to 
England in 1844, but the following year went again to Brazil 
and thence to Valparaiso for the purpose of exploring south Chile. 
He obtained a rich harvest. Amongst his earliest suecesstu! 
introductions from this region were Lapageria rosea, scallonia
