the swamp forest, with its exuberant growth, is plant life in the vigor 

 of youth. ... It is possible that the dry forest, with its open lands 

 or ' campos,' represents an older flora." 1 



2. Collections Made in Brazil, Bolivia, Paraguay, and Argentina 

 by Mr. and Mrs. H. H. Smith in 1885 and 1886. 



The following notes are taken from letters from Mr. Smith to the 

 author, dated December 6, 1908 and April 24, 1905. 



Brazil. 



" Cachoeira : This is a stream, or small river, which rises near Cha- 

 pada, flows N. then N.E. and finds its way to the R. Cuyaba. The 

 collections with this label were made at a place about fifteen miles N.E. 

 of Chapada, where the river passes through a gap in the hills. Forest 

 and grass-land with some boggy places. Practically the same as 

 Chapada. 



" Chapada : A small village of Matto Grosso, Brazil, about twenty- 

 five miles E.N.E. of Cuyaba, on the plateau. The village itself is 

 about 2,500 ft. above sea level, or 1,800 ft. above Cuyaba; but col- 

 lections are from all the surrounding region as low as 1,500 ft. This 

 is a country of mixed forest and campo, or grass-land with scattered 

 trees ; there are many streams — some small lakes or ponds, and tracks 

 of more or less boggy savanna where the streams rise. 



"The name Chapada is really a generic appellation, applied to the 

 plateau in general. The real name of this village is Santa Anna La 

 Chapada, and in some maps it appears as Santa Anna ; but in all that 

 region it is known simply as Chapada, or the Chapada. 



" Cuyaba: The capital of Matto Grosso, on the R. Cuyaba, a 

 branch of the Paraguay. There is very little flood-plain here ; mostly 

 rocky land, but well watered by streams. 



" Corumbd : A town on the River Paraguay, near the junction of 

 the Taguary, the port of entry for Matto Grosso. There is a tract of 

 dry rocky land, a kind of island, in the flood-plain of the Paraguay, 

 which is here very extensive. Collections were made principally on 

 the flood-plain ; the waters were rising, but I used to wade about with 

 a boy pushing a canoe through the grass behind me. These flood- 

 plains are mostly open grass-land, with some forest along the river and 

 channels.
