Excerpt from Biologia Centrali-Americana, or Contributions to the Knowledge of the Fauna and Flora of Mexico and Central America, Vol. 1: Botany At Kew it is the practice to post up all proposed new genera as they are published, and from a cursory examination of their claims to this rank (in Bentham and Hooker's sense) the number of distinct genera now known is about 8000; and, allowing a proportionate increment of new species, the total may be placed at Judging from the exceedingly large number of new forms in the latest collections from the Malayan Peninsula, Borneo, New Guinea, and Central China, future explorations will doubtless considerably increase these totals. Absolutely nothing is known botanically of immense tracts of the interior of Africa; whilst such comparatively well-explored countries as Mexico and Central America still continue to yield as much as ten per cent. Of new species in collections made out of the beaten tracks, and in a North Mexican collection of about 270 species made by C. G. Pringle in 1887, 20 per cent. Are indicated as new in a catalogue by A. Gray and S. Watson. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
