A new species of Boesenbergia and rediscovery of B. rotunda (Zingiberaceae) from India by AISHWARYA, K., M.R. VINITHA, GEORGE THOMAS & M. SABU* (Abstract A new species of Boesenbergia from northeast India is described and illustrated. Besides, the rediscovery of B. rotunda from India after a century is reported. In addition to morphology, data from anatomy, molecular biology and pollen morphology are also used.)
The history and identity of Boesenbergia longiflora (Zingiberaceae) and descriptions of five related new taxa John D. Mood, Linda M. Prince, J.F. Veldkamp and Santanu Dey (ABSTRACT. The history of Boesenbergia  longiflora (Wall.) Kuntze (Zingiberaceae) is reviewed, its identity is discussed and a lectotype designated. Five new, related taxa are described and illustrated: B. collinsii Mood & L.M.Prince, B. hamiltonii Mood, S.Dey & L.M.Prince, B. kerrii Mood, L.M.Prince & Triboun, B. kingii Mood & L.M.Prince, and B. maxwellii Mood, L.M.Prince & Triboun. A phylogenetic analysis of plastid trnK intron (including matK) and nuclear ITS DNA sequence data indicate these Boesenbergia species form a clade within Boesenbergia. Results of the molecular data analyses in concert with several diagnostic characters, support the recognition of the new taxa. Historical illustrations, colour plates, a field key to the species, a comparative table, a listing of the botanical history of B. longiflora, and a geographical distributional map are provided.)
