Nomenclatural remarks.

Borhidi (2017a) attempted to transfer this species to Palicourea   , but overlooked the preexisting Palicourea hispidula   Standl. This renders his name an illegitimate later homonym (ICN, Art. 53.1). Here, the new name Palicourea longiinvolucrata   is proposed that alludes to the long involucral (15-20 mm) and floral bracts (6-15 mm) that help differentiate this species from the closely related Palicourea hoffmannseggiana   (Roem. & Schult.) Borhidi (3.5-15 mm, 0.5-2 mm). Two further species, Palicourea gracilenta   ( Müll. Arg.) Delprete & J. H. Kirkbr. (3-7 mm, 1.5-5 mm) and Palicourea winkleri   Borhidi (both 1-9 mm), belong to the same species group (e.g., Taylor 2004, 2014), but have less-congested inflorescences (Figure 1 View Figure 1 ).

Distribution.

Palicourea longiinvolucrata   is known from Belize to Bolivia, from Venezuela and from Brazil ( Taylor 2014).
