No country of equal area presents a richer or more varied vegetation than Mexico.

What I would venture to suggest is a work in 8vo, without plates, scientific yet intelligible to any man of ordinary education; and, the country that I particularly have in view is the British West Indian Islands, so rich in useful vegetable products. I have reason to know that a very able botanist, Dr Griesbach [sic], is only deterred from publishing this Flora, by the fact that such works are not remunerative to the author … A sum of £300 would be required.

In tropical America … the flora has been studied from isolated centers with little regard for the species accepted at other centers, but with the assumption that each area is floristically distinct. Correlation through monographic work, covering a genus throughout its range, will reduce the species that have been multiplied unnecessarily.

Adverso ha sido el destino de las obras que sobre la flora de nuestro paí se han escrito.
