Cryptocoryne spiralis (Retzius) Fischer ex Wydler var. huegelii (Schott) Bogner

Cryptocoryne huegelii Schott with its synonym C. tortuosa Blatter & McCann were up to now regarded as synonyms for C. spiralis. In 1993 the var. cognatoides was described. In 2013, Bogner described both the new var. caudigera and C. huegelii as a variety of C. spiralis. Besides the big size of this plant (up to 75 cm), also the habitat is different, growing at much higher elevation in the Western Ghats.
