Notes: — Cook (1979) in his revisionary work mentioned ‘Type: Burma, Sagaing (Segain, Segaen) 1826, Wallich 2096 (Holotype:? CAL n.v.; isotypes: G, K-W, LE’. As mentioned by Cook (1979), we were unable to find the Wallich’s specimen (cat. no. 2096) in CAL, G, and LE. However, we were able to find two specimens that match the protologue in the K Herbarium (K001115130 and K000729615). The specimen K001115130, which is housed in the Kew herbarium, is recognized as the lectotype in accordance to Art. 9.3 (Turland et al. 2018).
