Cryptocoryne moehlmannii de Wit

An excellent aquarium plant, easy to grow, easy to multiply. Collected twice in west Sumatra near Sasok. There are hardly differences with Cryptocoryne pontederiifolia, only the limb being more twisted oblique, having a relative low collar zone.

The same plant with more broad ovate leaves. Too many plants in the pot!

Distribution C. moehlmannii in Western Sumatra.
       

Probably all C. moehlmannii plants in cultivation descend from one collection made in 1977 by Jähn, who shipped them to Möhlmann.
At that time the only known form of Cryptocoryne pontederiifolia was with the broad, pure yellow limb with a very high collar zone. See the page on C. pontederiifolia.

The plant is named in honour to Friedrich Möhlmann (1920-1991), an excellent grower of Cryptocoryne.
