Justicia petiolaris leaves

The long-stalked, opposite leaves of this Justicia petiolaris plant in picture twist more than they wave. Some leaf parts show regular oblong bulges between the parallel lateral veins that curve up. The leaf margins are entire, the tips bluntly pointed.
This plant is an evergreen. Flowering happens quite low down from the leaf axils of the young plant (Pooley, et al, 2025; Manning, 2009; Pooley, 1998; iNaturalist).
