Note
Echinodorus virgatus was probably described from a single collection from Tepic in the state of Nayarit, Mexico (Hooker & Arnott 1838). There are no later collections and the taxon is considered extinct (Lot et al. 1999). According to Haynes & Holm-Nielsen (1994), this taxon differs from the other species, especially from other Mexican species. The distinguishing features are translucent lines, winged rachis and round glands in the fruits (Haynes & Holm-Nielsen 1994). These features are typical of E. palaefolius, and phylogenetic analysis has identified E. virgatus as sister with few morphological differences in consecutive characters (Lehtonen & Myllys 2008).
