NATURAL HISTORY SOCIETY, MAURITIUS. 357 
leaflets are from 30 to 35 in number, linear and mucronated : 
the fruit straight, beset with some scaly bristles. M. Bojer 
calls this species C. jilipendula: we do not possess it at 
Mauritius. 
Lastly, M. Bojer has described a beautiful kind of Ipomea, 
which he has named J. glaberrima. Its aspect presents much 
affinity with Z. Bona Nov; but it differs essentially in the 
capsule, the seeds of which are black and furnished at the 
top with a tuft of silky hairs. The Ipomea glaberrima grows 
in the island of Seychelles Archipelago, at Comora, and is 
also found on the eastern coast of the African Continent, at 
Madagascar, and at Diego Garcia. It is cultivated in some 
gardens of this island, and blossoms in September and 
October. 
Finally, M. L. Bouton has made known 2 species of 
Geniostoma, which grow in the interior of the thick forests 
in Mauritius, he has named one G. pedunculata, in reference 
to the long footstalks which support the fruit, and the other 
G. cordata, from the heart-shaped form of its foliage. "These 
two species are perfectly distinct from the Anassa or Genio- 
stema Borbonica. 
M. L. Bouton has communicated some details on different 
plants which exist in the Mauritius, whether indigenous or 
cultivated, and which are new to Science, or have been 
hitherto known by incorrect names. By this means M. L. - 
Bouton has ascertained, through his communications with 
the scientific men of Europe, and chiefly with Professor 
Hooker of Glasgow, that a Terminalia cultivated at Mon- 
plaisir, and which flowered for the first time in 1830, is the 
T. Bellirica of Roxburgh. He has also established the fact, 
that Sandoricum Indicum is the correct appellation of a tree 
which is cultivated in several parts of the island under the 
name of Bastard Mangosteen, and is enumerated in the 
catalogue of Mauritian plants, as Trichilia costata. 
M. L. Bouton has likewise collected many of those Ferns 
which adorn the great forests of Mauritius, and convinced 
himself that several species grow in this country which are
