Nomenclatural novelties in Polygonatum (Asparagaceae) and notes on some recent species distributions.

Several nomenclatural changes in Polygonatum (Asparagaceae) are made based on field, herbarium, and molecular studies. Polygonatum govanianum is recognized at specific rank, P. dolichocarpum is considered a synonym of the earlier P. gongshanense, and P. sinopubescens is treated as a synonym of P. filipes. Maps of distribution are included for P. campanulatum and P. gongshanense which are newly reported for Myanmar, and for P. tessellatum which is newly reported for India. [ABSTRACT FROM AUTHOR]
