Abstract
The genus Ischaemum Linnaeus (1753: 1049) was established with two species, viz. I. muticum Linnaeus (1753: 1049) and I. aristatum Linnaeus (1753: 1049). At present, the genus comprises ca. 71 species distributed in warm and tropical regions of the world (Mabberley 2008). It is represented by 56 species in India of which 43 species are endemic (Srivastava & Nair, 2010). In recent years, the genus has attracted the attention of many researchers for novelties in taxonomy (Gorade et al. 2016, Sunil et al. 2017), distribution (Datar et al. 2014) and nomenclature (Tiwari et al. 2016).
