About this species

Dracaena jayniana was recently identified as a new species by a team including Kew botanist Paul Wilkin and collaborators in Thailand, the Netherlands and Poland. It is named in honour of Jayne Spasojevic in recognition of a charitable donation by her husband to a sponsored skydive in aid of Portfield School in Dorset, UK. The epithet also sounds like the Thai vernacular name Chan.

Dracaena jayniana is part of a group of species related to the Canary Islands dragon tree D. draco.
