lemna
The Lemna family has many members within it. However, there are some unifying and differentiating characteristics which exist between each member. These characteristics help us identify each member of the group. Lemna Triscula lives in an aquatic habitat along with every other member of the Lemna group. Similar to Lemna Turiorifera and Lemna minor. It has one root per thallus with a length ranging from 3-15 mm (http://www.bsbi.org.uk/Lemna_Crib.pdf). Its thallus is ovate as it is shaped like an egg. Its thallus is a little fattened on one side or more in cross section. Lemna Turiorifera's obovate thallus is approximately 1-4 mm. The widest point is lovated above the middle of the leaf blade in Turiorifera. Lemna Japonica is very often red coloured on its upper and bottom surface, just like Lemna Obscura. Lemna Japonica has its mostly distinct papillae on its upper surface whereas Lemna Obscura has its mostly distinct papillae near apex.
Lemna Japonica has approximately 3-5 veins and it is originated from the hybridization which occurred between Lemna Minor and Lemna Turiorifera (https://gobotany.newenglandwild.org/species/lemna/turionifera/). Lemna Obscura has roots with their maximum length being 15 cm and the tip of its frond is mostly rounded. Lemna Minuta has the least amount of veins (0-1 veins) and its dull pale green fronds are about 1-3 mm. It's fronds are usually symmetrical, obtuse and have a slight point. However, Lemna Minuta has a very shallowly ridged upper surface.
Lemna Gibba possesses its name because it is gibbous to flat. It has roots which are 3.5-6 mm long and 4-5 separate veins from its base. Lemna Gibba has relatively a low amount of distinct small cells on the outside and large cells in the middle. Lemna Minor possesses small cells all over its surface (IBID). Lemna Minor is a dark green plant which shines and its fronds are asymmetrical which are rounded without a point. Lemna Minor has 3-5 veins and is flat and smoothly rounded.
