GEORGE GARDNER; on the Structure and Affinities of the 
Plants belonging to the Natural Order PoposTEMACE&. 
(From the Calcutta Journal of Natural History.) 
A valuable Memoir on this curious and little-known na- 
tural family: the result of the author’s investigations is 
that Podostemacee are nearly allied to Nepenthes, the absence 
of albumen and the connection of the stamens in the latter 
being the chief distinguishing characters. Mr. Gardner 
describes fully all the species that have been detected in 
India, and which belong to two Genera, Tristicha, Thouars, 
and Podostemon, Rich. Until the publication of Dr. Wal- 
lich’s Catalogue, 1828, no species was known to exist in the 
East Indies. The above-mentioned Catalogue gives one as 
a native of Sylhet. In the year 1835, another species was 
added by the late Mr. Griffith. In 1845, Mr. Gardner, in 
company with Dr. Wight, detected three new species on 
rocks in rapids in the bed of the Pycarrah River, in the 
Neilgherry Mountains; while in Ceylon, Mr. Gardner has 
added four others: thus no less than ten distinct Indian 
species are described in this work; and we know that the 
author has distributed to his friends in Europe beautiful - 
specimens of his discoveries.
