The same habitat. None of the plants flowered.
It is not known if they also grow emerged on the banks.

In 1985, Jacobsen and Bogner found C.
villosa. The bottom is apparently strong enough to have Bogner stand on one leg.

The first, in 1979 by S. Jähn collected plants
of C. villosa. Note the long white part of the petioles, indicating that they are
deep rooted, probably in a soft substrate of decaying debris.

The 1985 plants developed very good in emersed
cultivation, but not for very long.

The distinct red dots in the throat and the open
margin of the seam of the tube are also seen in C.pallidinervia (the latter from
Borneo) .

A nice drawing of C. villosa is found
in de Wit(1990). Note the detail of the haired limb.

Distribution of C. villosa on Sumatra
(Indonesia). Central Sumatra is a very interesting locality, you find here also C.
scurrilis and C.longicauda. |

Cryptocoryne villosa is still a very rare species. It has a very narrow
distribution and by that, it may be a threatened species. Today cultivation techniques are
improved and we may hope that it propagates soon. But it is certainly not a 'good'
aquarium plant.
