Ptychosperma sp. (Black Seed)

Native to New Guinea and northernmost Queensland, Australia, this very strong growing, clustering, slender stemmed and quite fine leafed species has not yet been described. Its attractive fruits change in color from cream to red/purple and are black at maturity. It is a beautiful palm that, judging from its speedy growth and robust nature, would make an excellent landscape alternative to the overused Ptychosperma macarthurii for tropical areas.

The Encyclopedia of Cultivated Palms is the definitive account of all palms that can be grown for ornamental and economic use. Palms are often underutilized as a result of their unfamiliarity—even to tropical gardeners. To help introduce these valuable plants to a new audience, the authors have exhaustively documented every genus in the palm family.
825 species are described in detail, including cold hardiness, water needs, height, and any special requirements. Generously illustrated with more than 900 photos, including photos of several palm species that have never before appeared in a general encyclopedia, The Encyclopedia of Cultivated Palms is as valuable as an identification guide as it is a practical handbook. Interesting snippets of history, ethnobotany, and biology inform the text and make this a lively catalog of these remarkable plants.
