Cryptocoryne pallidinervia Engler |
Though this plant is not very rare in nature, it is seldom imported from Borneo. It
grows in the peat swamp forests of Sarawak and West Kalimantan under extremely acid
conditions (pH 4 or so). Recent imports are from Anderson (1957), Driessen (1975) and
Kettner (1988).

Even in a simple mixture of sand and peat litter (with an
artificial fertilizer) it is very easy to grow Cryptocoryne pallidinervia. But
you don't see any pallid nerves, as you might expect.

Sometimes the spathe-leave is not closed to form a tube. This
rather uncommon but is seen in more species. The red dots reach far into the tube.

In my cultures, the limb of the spathe, when opening,
immediately folds up backwards. The limb is rather warty, the throat is densely spotted
with fine red dots.

The kettle of C. pallidinervia is dark purple
inside. The naked part of the spadix is very short, the male and the female flowers
reaching each other.

According to Anderson, the species is wide spread in the peat swamp forests

In 1970 De Wit described 'C. venemae' from material
collected by Haviland.

Known distribution of C. pallidinervia. Kettner and
Witte found the plant almost along the road near Sibu.

The very best way to cultivate C. pallidinervia is to use pure beach tree
soil. See for example Jacobsen 1992. The plants develop a very luxurious foliage with the
promised pallid nerves.
