appears to have a considerable similarity in habit and in the structure 
of the stigmata and ovarium. And a similar correspondence exists, 
as far as can be judged from a drawing in the Botanic Garden at 
Calcutta, with another unpublished plant from Sylhet, probably 
forming a second species of Dr. Wallich’s Sarcostigma*. 
Lastly Mr. Griffith characterizes a new genus of Anacardiacee, 
under the name of 
Gen. Swintonra, Griff. ~ 
Sepala 5, basibus coalita, persistentia. Petala 5, hypogyna, sub fructti 
demim ampliata. Stamina totidem, toro cylindrico partim elevato 
insidentia. Ovariwm subzequilaterale, in apice tori staminiferi sessile. 
Stylus filiformis ; stigma peltato-capitatum. Fructus siccus, exstipi- 
tatus, petalis ampliatis foliaceis suffultus.—Arbor magna, resinosa, facie 
guodammodé Mangifere. Folia lanceolata, coriacea. Panicule azil-

This genus is dedicated to George Swinton, Esq., late Secretary 
to the Bengal Government, who has always been ready to promote 
the interests of science and the welfare of the Tenasserim Provinces, 
and to whom Dr. Wallich had intended to dedicate his genus Mela- 
norrhea. In the structure of its fruit it is very nearly allied to Me- 
lanorrhea; and in that of the flowers, particularly as regards the 
mode of adhesion of the petals and stamina to the torus, it ap- 
proaches to Syndesmis of the same author.
