Weinmannia marquesana var. angustifolia (Cunoniaceae), a new variety from the Marquesas Islands

摘要

Weinmannia marquesana F. Br. var. angustifolia Lorence & W. L. Wagner, var. nov., a new variety with narrow, simple leaves endemic to Tahuata, Marquesas Islands (French Polynesia) is described and its affinities and conservation status are discussed. It is similar to the other two varieties of this species by having simple leaves, but this new variety has much narrower leaf blades, and it resembles Weinmannia tremuloides in having narrow leaf blades but differs by having simple, not trifoliolate leaves.
