Trochilus (petasophora) coruscans, a beautiful species al-lied to the Anais, but whose locality is unknown to me. 19. Trochilus ( ?) flabellifera, which is nearly allied to, but a much larger species than T. mellivora, said to inhabit Mexico ; and 20. Trochilus ( ?) strophianus, a fine new species of the same form as the Clarisse and the Parzudaki. BOTANICAL SOCIETY OF EDINBURGH. June 11, 1846. — Professor Balfour, President, in the Chair.

In this communication Mr. D. alluded particularly to the rapidity of its growth, and to its non-spiral nature, in the specimens of the pistilliferous plant grown by him ; he also noticed the rapid evolution of gas from the plants when placed in the sun. 3. *' Remarks on the Greenheart, or Beeberu-Bark Tree of Deme-rara," by Dr. G. R. Bonyun. Dr. B. stated, that the description of the parts of the flower as given by Schomburgk, is not quite cor-rect, and thinks that the plant cannot be referred to the genus Nee-tandra. According to Dr. Bonyun, it has an 8, 10, or 12-partite perigone, outer segments persistent, stamens varying from twelve to Ann. $ Mag. N. Hist. Vol. xviii. 2 H
