The genus Cycas (Cycadaceae) in Thailand

Brittonia Aims and scope Submit manuscript

Abstract

The genusCycas is revised for Thailand. Ten species are enumerated, five of them described as new (C. chamaoensis, C. clivicola, C. litoralis, C. nongnoochiae, C. tansachana), with one new subspecies (C. clivicola subsp.lutea). The species are placed within an infrageneric classification previously outlined. Distributions of the taxa are mapped, eight of the species are illustrated, and a key to species is provided. Previous records ofC. circinalis andC. rumphii from Thailand (here not regarded as indigenous in Thailand) are discussed.
