NARRATIVE. 
IN the month of June 1891 I heard from Mr. Carruthers, Keeper of the Botanical 
Department of the British Museum, that a botanist was required to join an expedition 
about to explore the Brazilian province of Matto Grosso. As I had been for years 
desirous of rendering my botanical education less incomplete by a visit to the Tropics, I 
readily acquiesced in Mr. Carruthers's suggestion that I should offer my services in the 
above capacity. On enquiry it was understood that a syndicate had obtained mineral 
rights over two large traets of land in the province, the conditions comprising a survey 
and a geological and botanical examination of the territories in question, which included 
the country to the east of Cuyaba, the capital, and the large and almost entirely 
unknown region lying west of the fifty-seventh meridian, and between the tenth and 
fifteenth parallels of latitude. My offer was accepted on the part of the syndicate, and 
on July 2nd, after hasty preparation, I left Southampton in the company of Dr. John 
William Evans, who had been appointed geologist to the expedition. 
Matto Grosso has been visited by several botanists, and, thanks to their united labours, 
the vegetation of a considerable part of the province is now fairly well known. "The van 
appears to have been led by a Portuguese doctor, Alexandre Rodriguez Ferreira, who, 
departing from Pará towards the end of last century, made his way up the Madeira and 
Guaporé rivers to the then flourishing city of Matto Grosso (Villa Bella). He returned 
by the same route, and deposited his plants in the Museum at Lisbon, whence a set was, 
a few years ago, sent to the Herbarium at Kew. In 1825 Riedel, botanist to the Russian
