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.

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.
