The Gentianaceae family is wildly diverse, with members ranging from annual and perennial herbs, to shrubs, to tropical trees and woody lianes. Their wide range means that many species of Gentiana are popular in gardens, especially those cultivated as rock garden or herbaceous border perennials. Flora of the Guianas Gentianaceae takes a critical, illustrated look at this family as it appears in Guyana, Suriname, and French Guiana. The volume includes species descriptions, distribution, habitat, and vernacular names, as well as line drawings throughout.
