Since Düll reduced P. leptostachya to varietal rank as P. blanda var. leptostachya [Bot. Jahrb. Syst. 93(1): 110 (1973)] it is commonly known under that name. However, there is no proof at all that there is any particular relationship between the Old World P. leptostachya and the New World P. blanda. Moreover, also in the Americas P. blanda appears to be one of the most misappleid names and it looks like this species is restricted to northern Venezuela [Zanotti et al., Darwiniana 50(1): 135 (2012)]. A strong plea is made to revive P. leptostachya at specific rank [Mathieu (2020: 248)].
