  Neotropical Plagiochila surinamensis differs from P. (sect. Rutilantes) gymnocalycina in having fragile leaf teeth. Phylogenetic analyses of nrITS sequences of several representatives of P. sects. Rutilantes and Arrectae lead to a well-resolved topology in which P. surinamensis is placed sister to P. gymnocalycina with good bootstrap support. The phytochemical profile of a deuterochloroform extract of P. surinamensis consists essentially of 4-hydroxy-3 '-methoxybibenzyl and β-phellandrene, a combination observed previously in P. gymnocalycina only. Based on this topology and the morphological and phytochemical similarities, P. surinamensis is reduced to a variety of P. gymnocalycina. Plagiochila wolfii is placed in the synonymy of P. gymnocalycina var. surinamensis.
