Lectotype (Step I: Vide Graham & Gandhi (2013: 80); Step II: designated here):— s.loc., s.d., N. Wallich 2106 (K, K001115171!, isolectotype: Wallich 2106? K, K001115172!)

Notes: —The name proposed by Heyne was validated by Clarke (1879) based on Wallich’s (1828) specimen (catalogue numbers 2106 B and C). Stating “ Lectotype: Wallich cat. No. 2106 (K),” Graham & Gandhi (2013) established the Wallich specimen in K as the lectotype (first step) according to Art. 9.3 of the ICN (Turland et al. 2018). In Kew herbarium, there are five specimens K001115170–74, belonging to the same gathering of Wallich cat. no. 2106. K001115171 and K001115172 are barcodes of Wallich cat. no. 2106 B and 2106 C respectively.According to Art. 9.17 of the ICN, we have selected K001115171 (K) as the lectotype in this case since it matches with the protologue quite well (Turnland et al., 2018). This constitutes a second step lectotypification.
