Comments:

(1) A distribution of Chloothamnus elegantissimus in Thailand and Vietnam was stated in the World Checklist of Bamboos and Rattans, 2016: p. 131, under "Nastus elegantissimus" [#1221], but a natural occurrence in these countries is most unlikely.

(2) No records were found on the introduction of Chloothamnus elegantissimus into Thailand.
