A small bushy tree, found growing on the beach of the Rio Para, 
near Caripi. It is closely allied to P. ferrugineum of Schott, from 
Southern Brazil, but, on a careful comparison with my specimens of 
that plant gathered by Sello, ours appears to differ both in the shape 
of the leaf,longer in proportion to its breath, and in the small size 
and round shape of the flower-heads. 
The Monocotyledones are, for the most part, well-known species, 
although some of them are not common. They include twenty-four 
Cyperacee and twenty-two Graminee. Among the former is a speci- 
men, not in flower, which very much resembles the Cyperus articulatus, 
L., of which, Mr. Spruce informs us, the tuberous root is sweet-scented, - 
and is used as a perfume ; and an Zeocharis, of the section Chetocyperus, 
which has been distributed as new, under the name of E. arenaria. A 
further examination, however, induces me to suspect it may be a mere 
variety of Chetocyperus bonariensis, N. ab E., differing in the number 
of sete, six instead of three, and the more distinctly granulate 
achenia. It forms large patches on the beach at Caripi, and serves to 
bind the sand. 
The Soridium Spruceanum, Miers, a new genus, and by far the most 
interesting plant of the collection, is fully described by Mr. Miers in 
|  & paper read before the Linnzan Society, and about to appear in the 
‘Transactions of that body.

. . On the opposite bank we were delayed some hours, waiting for a 
guide, whom we expected to follow us. Four roads meet here, 
or rather forest-paths, and all are difficult to find. Being now in 
Sikkim, and beyond the British ground, any one guiding Europeans is 
liable to punishment; and though the road we sought is so unfre-
