BOTANICAL NOTES. 661 
we embark on the Rio Esmeraldas in a light canoe, formed 
of a single trunk, and glide rapidly down the stream, so 
shallow for the first few miles, as scarcely to float the tiny 
craft. The depth of water is, however, soon increased by the 
influx of several tributary branches, and with scarcely any 
propelling effort we reach the mouth of the river in less than 
a single day—a distance of about sixty miles. The course of 
the stream is invariably downward, and under the most 
favourable circumstances it requires ten days to accomplish 
the ascent. Its banks are clothed with forest trees, occasion- 
ally varied with savannahs of luxuriant Guinea grass. From 
the rapidity of the voyage I did not enjoy the opportunity of 
examining this extremely fertile country.

Gardner’s first Organ Mountain Collection. By Joun

Dear Sir William,—Dr. Lindley has just returned my 
Organ Mt. Orchidez, which he kindly undertook to deter- 
mine for the enumeration of my collections; but, not having 
leisure at present to continue it, I send you for publication 
the characters of four new species, which I find he has 
established. To these I add the distinctive character of a 
new Cattleya from the interior.
