ANALYSIS OF THE PROCEEDINGS OF THE NATURAL 
HISTORY SOCIETY OF MAURITIUS, DURING THE 
YEAR 1830. (ExTRACTED.) 
Botany.—The empire of Flora, formerly so extensive in this 
island, but now more and more restricted by the daily in- 
crease of cultivation, still contains sufficient to occupy the 
attention of persons who devote themselves to this study. 
Aublet, Commerson, Du Petit Thouars, Willemet, Noroühas, 
Ventenat, La Billardiére, Bory, Stadtmann, and more re- 
cently MM. Heraud, Sieber, Gaudichaud, D'Urville, Hils- 
enberg, and our colleague, M. Bojer, have doubtless made 
known many of our plants; but a great number of species 
still remain to be described. 
M. W. Bojer, who is Professor of this Science at the Royal 
College, and who reckons among his students many members 
of the Natural History Society, has, at various of its meetings, 
imparted his discoveries. | A Hibiscus, which he . found 
growing wild in the forests of this island, and which has 
long been cultivated in our gardens, forms the subject of an ~ 
essay that he has communicated to the Society: this tree was 
principally observed in the district of the Riviére Noire, on 
the property of our colleague, M. Genève, and it has received 
the name of Hibiscus Genevii. The Syphomeris Lingum, 
(Bojer, 1), a genus which M. Bojer established some time 
ago, and the Grewia ulmifolia, a new species, which we equally 
owe to him, have, as well as the Tanghinia veneniflua (Petit 
Thouars), been described and drawn by M. Bojer, with ex- 
treme care and exactness. This gentleman has devoted him- 
self to the delineation and description of all the varieties of 
Mango ( Mangifera Indica, L.), which are so common in the 
island, and he has collected 70 kinds. Itis evident how desirable 
it is to have a scientific definition and an accurate representa- 
tion of all the various sorts of a fruit that is so useful to man- 
kind. Mrs. Charles Telfair, Miss Baigrie, and M. E. Duvi- 
vier,- have assisted M. Bojer in his drawings, and M. Nolin 
has furnished him with some beautiful fruits that he raised in -
