Noções botanicas das especies de Nicociana mais usadas nas fabricas de tabaco, e da sua cultura

A meticulous early‑19th‑century guide walks the listener through the botanical world of the Nicotiana genus, the plants whose leaves have long powered the tobacco trade. The author blends the natural classification of Jussieu with Linnaeus’s artificial system, detailing the calyx, corolla, stamens and seed capsule in clear, observable terms. Readers gain a concise picture of how the flower’s five‑lobed structure and the plant’s oily, reniform seeds set it apart from its botanical relatives.

Beyond taxonomy, the work offers practical insights into cultivation across climates, from the humid soils of Brazil and the Caribbean to European gardens. It describes how stem height, leaf shape and flowering time shift with temperature and soil fertility, noting the plant’s annual habit in colder regions and its perennial vigor where warmth endures. The text also highlights the varieties still favored by tobacco factories, linking botanical form to the flavor and strength prized by producers.
