Comments:
(1) There is a mature plant of var. amoenus grown in Mae Taeng District, Chiang Mai Province, which was planted more than 10 years ago (ธ. บ., pers. comm., 2 Feb. 2014, photos seen).
(2) A variety of Dendrocalamus minor, named "variegata", which is displayed in plantjdx.com [#1345] as "Dendrocalamus … minor varigata 花頭吊絲竹" (huā tou diào sī zhú), is the same as var. amoenus.
