Notes: —The following field numbers were cited in the protologue of Ocotea lanceolata: Wall. Cat. n. 2599 A–E. It was further specified: “Crescit in Sillet (F.D.) et e Sillet in Hortem Calcutta numillata; in Napalia (Wallich a 1820 et 1821).” They correspond to the Wallich, Numer. List Nos. 2599A, 2599B and 2599C. Of the available specimens which we could examine, Wallich 2599C from Nepal (K001116537) is the best specimen with flowers and fruits and the same is selected here as the lectotype of the name. As regards Laurus lanceolaria, there are four collections of Roxburgh at BM and MO from Bangladesh (BM014605560, BM014605561, MO-247600, MO-255220). The MO specimens bear the label with the annotation “Ex Herbario Musei Britannici” and it indicates that both MO specimens were distributed from BM. The specimen BM014605561 bears two flowering twigs and two ticket size labels with the name “ Laurus ” and “Sundegool” in Roxburgh’s handwriting while there is no annotation by Roxburgh on the other BM specimen BM014605560. It may be noted that Roxburgh stated in the protolouge: “Sundhigool, the vernacular name in Silhet where it is indigenous”. Although, there are two original Flora Indica drawings of Roxburgh available at CAL and K, we have prioritized the specimen over the drawing for lectotype selection. Hence, the specimen BM014605561 has been selected here as the lectotype of the name. Phoebe lummaoensis was differentiated with P. lanceolata but unfortunately the range of variation of the latter was not taken into account while describing the new species which is synonymized here. Likewise, the peninsular Indian population, representing a variant with shorter, few-branched panicles with fewer flowers was described as P. palghatensis. Here also the range of variation of the species was not taken into account.
