Morphology
This is a straightforward taxonomic noun phrase: 'genus' (a biological rank) combined with the proper name 'Najas' yields 'the genus called Najas.' If a learner knows both constituents, the meaning — the group of related species named Najas — is directly derivable. The construction 'genus + name' is a regular, cross-linguistic compositional pattern, so it is transparent despite being technical vocabulary.
Etymology
Genus Najas comes from the name Najas, linked to the word 'naiads', the water nymphs of old stories, and genus, which means a group or kind. These plants are delicate and live in fresh water, so the name gives the image of a 'group of water-nymph plants' and is used for this group of aquatic plants.
