Zingiberaceae, known as ginger family, is a family of monocotyledon belonging to the Zingiberales order. This family is widely used its rhizome for various purposes, especially as medicinal plant. The morphological characters can be used to help the identification of species in the field of plant taxonomy. The aim of study was to characterize the morphological traits, both vegetative and generative organs, of Zingiberaceae from Serang District, Banten. Plant specimens were collected from Serang District, Banten, including in Pabuaran, Gunungsari, and Ciomas sub-district using purposive sampling. The examination of morphological characters data was conducted through observation and documentation. There were 13 species/varieties of Zingiberaceae collected from the studied area, i.e. Amomum compactum, Alpinia purpurata, Curcuma xanthorrhiza, C. longa, C. heyneana, C. mangga, C. aeruginosa, Kaempferia rotunda, Etlingera elatior, Zingiber zerumbet, Z. officinale, Zingiber officinale var. rubrum, and Z. cassumunar, in which the generative organs were found only in eight species/cultivars of them. Based on the morphological characters of vegetative organs, thirteen species/cultivars had a similarity distance coefficient from 37% to 94%; while based on the morphological characters of both vegetative and generative organs, the eight species/cultivars had a similarity distance coefficient from 31% to 94%. The results showed that using the characters of vegetative organs data were still able to provide consistent grouping results with the generative organs.
