Extract from the Proceedings of the year 1831. 
Botany.—M. L. Bouton has communicated to us in a note 
some errors which relate to the Botany of our isle, and prin- 
cipally those which exist in the chapter that M. Lesson has 
edited, in the Zoological part of the voyage of the Coquille. 
According to our colleague, no kind of Ixora or Cinchona 
grows in this island. M. Lesson speaks of a species of 
Rhexia, an evident mistake for Nuria. The errors that crept 
into the catalogue of plants, printed at Mauritius, in 1822, 
have been all repeated in M. Lesson's chapter, with pro- 
voking fidelity. 
The same member has réad some observations on the 
monograph of the Orchidee of the Isle of France and Bour- 
bon, by M. Ach. Richard; and contrary to the opinion of 
the latter, he maintains that our Flora has more analogy with 
that ofthe Continent of Africa than with the Indian Archipe- 
lago; still that the resemblance does not hold good with the 
vegetation of the southern extremity of Africa, but only with 
that part which lies near the Mauritius, and is equally situated 
between the tropics; especially the coast of Zanzebar, which 
has been explored by M. Bojer. : : 
_ Dr. Lyall has communicated to us verbally several obser- 
vations on the Euphorbia splendens (Bojer), and the Poin- 
ciana regia (Boj.), which grow at Madagascar, and are now 
cultivated in all the gardens of Mauritius. He mentioned a 
yellow flowered var. of the first, which he had found at 
Madagascar. ‘The same member has added 400’ species of 
Madagascar plants to the Society's herbarium. —
