The pantropical lycophyte genus Phlegmariurus Holub (1964: 21) (Lycopodiaceae) comprises approximately 250 species (PPG I, 2016) and despite extensive study, its taxonomy remains poorly understood (Ollgaard 1992, Field & Bostock 2013). In recent years, many species have been transferred to Phlegmariurus from the closely related temperate genus Huperzia Bernhardi (1801: 126) (Ollgaard 2012a,b, Field & Bostock 2013, Arana 2016, Duy et al. 2016, Field et al. 2016) and new species continue to be described from both the New World (Ollgaard 2015, 2016a,b) and Old World tropics (Hsieh et al. 2012, Duy et al. 2016).
