= Plagiochila heteromalla Lindenb.

Notes. – Plagiochila heteromalla is widespread in the Andes and is distinguished by the (sub)opposite and usually strongly secund leaves with a border of thick-walled cells, a vitta-like basal area, shortly toothed margins, shortly decurrent leaf bases and homogeneous oil bodies (GRADSTEIN, 2016). Plagiochila paludosa is identical to P. heteromalla and a synonym. The new lectotypification of P. paludosa was already proposed by J. Heinrichs on an annotation label.
