ANALYSIS or tae PROCEEDINGS or rug SOCIETY 
or NATURAL HISTORY, iN rue Isando or MAURI- 
TIUS, DURING THE YEAR 1833. 
(Read on the 24th day of August, 1833.) 
Botanical part: drawn up by L. Bouron, Vice-Secretary of 
the Society, and Correspondent of the Museum of Natural 
History at Paris. 
Tuer year which has just elapsed is far from having proved 
fruitful in botanical labours; still some few cannot fail to be 
interesting to Science. M. W. Bojer has described and 
figured four remarkable plants, all natives of the great island 
of Madagascar, or of the numerous adjoining Archipelagos. 
One of these, long cultivated in some parts of Mauritius, at 
the garden of Monplaisir, at Reduit, &c., belongs to the 
family of Leguminose. As its aspect and habit offer many 
points of similarity to Potnciana regia, (Bojer,) it had been 
probably confounded with that species; but this beautiful tree 
having flowered for the first time in April last, its inflores- 
cence presented characters so different from Poinciana, and 
even from all other Leguminose, that M. Bojer found it 
needful to establish a new Genus for it, which he has dedi- 
. cated to the learned and worthy patron of our Society, the 
Honourable Sir Charles Colville.* 
This Genus, which, according to De Candolle's system, 
will rank in the Tribe Caster, is named by M. Bojer 
* This plant has since been figured in the Botanical Magazine, tab. 3325.
