Cryptocoryne consobrina Schott

2006, Sunil rediscovered Cryptocoryne consobrina in the highlands of Karnataka, India at ca 1000 m. For some years, it was assumed that another plant found in 1981 in Calicut (Kerala) represented C. consobrina. However a closer look by Josef Bogner lead him to the conclusion that this was not true and in 2006 he described it as a new species: C. sivadasanii. Be aware of this!
The pictures below represent the 'true' Cryptocoryne consobrina.

Herbarium specimen of C. consobrina
Nationaal Herbarium Leiden (L)
Though C. consobrina was already described in 1857, a detailed drawing was first given in Fischer (1936). De Wit (1990) mentions the the broad leaved form in his book. This form is not found up to now.

Distribution of C. consobrina in southern India

       
Around 1990, an unknown Cryptocoryne from a Shola forest (1300 m) in India came to Europe.

The plant never flowered in the greenhouse. In 2009 they were grown outdoors till October (when frost comes)

Only a bit shaded for full sun, they grew very well. They are also well suited for the aquarium.

In 2010 they developed 60 cm long, stiff and brittle leaves in the greenhouse. May be this is C. consobrina.

A striking feature of C. consobrina is the dimorphism in the leaves: undulated flaccid? submersed and longer, smooth, more or less broad stiff? emerged leaves.
M. Sivadasan was so kind to give me permission to use the photographs from the article.
