Obs. I have named this genus in memory of Sir Andrew Balfour, the founder of the Edinburgh Botanic Garden and Museum, of whose merits in natural history, especially in botany, an interesting account is given by his friend Sir Robert Sibbald, in a small volume, entitled, " Memoria Balfouriana."

72] Obs. The only true species of Nerium are, N. Ole- ander, odorum, and probably salicinum, Forsk.
Nerium Zeylanicum and antidysentericum, form a very distinct genus, which I have named Wrightia. N. coro- narium is probably a Tabernamontana, and N. divaricatum, from an examination of the specimen in Hermann's Her- barium, on which this species entirely rests, I believe to be the same plant. Nerium obesum, Forsk., seems to be sui generis : it cannot, at least, be a Nerium.
