Describing terminologies and discussing records: More discoveries of facultative vivipary in the genus J.Koenig (Zingiberaceae) from Northeast India.

The authors introduce the term facultative vivipary for the first time in gingers and elaborate on this reproductive strategy. Four new observations of facultative vivipary are reported in the genus which were discovered during botanical explorations by the authors in Northeast India (NE India) over the past three years. The viviparous taxa are C.B.Clarke, H. speciosum var. gardnerianum (Ker Gawl.) Sanoj & M.Sabu (previously, Sheppard ex Ker Gawl.), Buch.-Ham. ex Sm. and G.Lodd. The authors also attempt to summarise the occurrence of vivipary in the family Zingiberaceae from published reports and to clarify a taxonomic misidentification in a previously known report of vivipary in .
