Rotala wallichii ‘Long leaf’
This finely leaved Rotala is mostly sold as Rotala wallichii “Long Leaf”. However it resembles Rotala sp. “Nanjenshan” and possibly does not belong to the species Rotala wallichii. This plant is probably from tropical Asia. In its submerged form, it differs from R. sp. “Nanjenshan” by darker, more reddish coloration and upright growth. The shoots are up to about 5 cm wide. The submerged leaves are linear, to 1 mm wide and ca. 1,5-3 cm long, slightly tapering towards the tip. They are arranged in whorls of mostly 5 or 6. The upper side is light or medium green to yellowish or brown-red, the underside is pink. The stem is green and about 1,5 mm thick. The emersed plants have coarser, broader, light green leaves.
