L. yungensis as an ecotype of L. valdiviana. As
L. valdiviana Phil. is the older name (Philippi
1864), we are suggesting that the name L. yungensis Landolt should be synonymised to
L. valdiviana. This conclusion can be drawn on
the basis of the powerful method of GBS and is
also in agreement with the results of AFLP (Bog
et al. 2010) and other molecular methods (Bog
et al. 2020). This decision decreases the number
of accepted species of Lemnaceae from 37 (Sree
et al. 2016) to 36.
The special position of L. section Uninerves
within the genus was also supported by very long
branch lengths. This hints towards the point that
the species of this section had separated from
those of other sections for long time—in
