Abstract In the present study, we have re-visited Musa taxonomy based on morphological and molecular data. DNA sequence data (ITS, trnL-F) and population assessment reveal that Musa balbisiana var. andamanica and Musa sabuana should be synonymized under Musa balbisiana. Based on the present work, we recognize four species of Musa namely M. acuminata, M. balbisiana, M. indandamanensis, and M. paramjitiana in Andaman and Nicobar Islands. Keywords Andaman and Nicobar . Musa . Molecular markers . Synonymies
Introduction Andaman and Nicobar Islands are the largest archipelago system in the Bay of Bengal. It constitutes a unique flora and a high level of endemism (Singh et al. 2014). The Nicobar Islands constitute one of the hotspots of biodiversity with a variety of ecosystems (Myers et al. 2010). Approximately 10% of the angiosperm flora of these islands are endemic and taxonomy of several species of the archipelago is poorly known (Singh 2014, 2017; Murugan et al. 2016). Of all the taxa occurring on the Andaman and Nicobar Islands, banana family (Musaceae Jussieu) is one of the taxonomically difficult plant groups. Globally, the family is represented by three genera viz., Ensete (8 spp.), Musa (70 spp.), and Musella (1 sp.) (Table 1). The largest genus Musa is mainly distributed in the tropical Asia from Himalaya to Electronic supplementary material The online version of this article (https://doi.org/10.2478/s11756-020-00552-5) contains supplementary material, which is available to authorized users. * Arun K.

northern Australia (Kress 1990; Liu et al. 2010; Hareesh et al. 2017). Since time immemorial, the cultivated banana fruits (berries) have been consumed raw/ ripened. Other parts of the plant like, pseudostem and leaves have been used by the local tribal people and by settlers for various purposes (Roux et al. 2008; Singh 2014, 2017; Singh et al. 2018). The economic utility of banana has attracted several plant breeders and researchers to develop new varieties (Liu et al. 2010). Taxonomy of the wild Musa species is complex (Argent 1976; Simmonds and Weathercup 1990; Gawel et al. 1992; Liu et al. 2002, 2010; Häkkinen and Väre 2008; Joe and Sabu 2016, 2019). Based on molecular phylogenetic studies on the genus Musa, two sections viz., Musa sect. Musa and Musa sect. Callimusa have been recognized (Nayar 1952; Li e
