Cryptocoryne pontederiifolia Schott

Cryptocoryne pontederiifolia is a plant with an interesting hsitory - if you like that, read the story below. It proved to be an excellent aquarium plant, today mass cultivated and sold all over the world.

Variation in the limb of the spathe of C. pontederiifolia. The collar is extreme high. The limb is slight twisted. The spathe can reach 10 cm length.This is the 'classical' form, widespread in cultivation.

A form with a less pronounced collar and with red dots on the limb.

Another plant from Wongso's collections shows distinct red dots on both the limb and the collar zone.

Only a few plants from Jacobsen's NJ 85-29 collection showed an even red collar zone and limb of the spathe.

A form found in the Leuser Reserve in North Sumatra with a deep red, rather narrow limb of the spathe.

Occasionally you will see an oblique twisted limb in C. pontederiifolia.

The kettle of C. pontederiifolia has a constriction in the upper part (this is seen in much more species) and verical grooves in the lower part. The kettle wall is somewhat translucent. Exactly as in C. moehlmannii.

Holotype of C. pontederiifolia from 1833 (!) near Padang

Niels Jacobsen discovered in the old Korthals plant an immature spathe between the cataphyls.

Known distribution of C. pontederiifolia.

The by Korthals in West Sumatra collected plants which were described by Schott 1863 as Cryptocoryne pontederiifolia. Unfortunately the plants were sterile and this would cause a lot of confusion.
Around 1975, crypts imported from 'Java' flowered at with a distinct yellow limb of the spathe. De Wit (1976) described them as a new species 'C. sulphurea'. In the same time, When C. ferruginea was found on Borneo, and not recognized to be this species, one thought it might be C. pontederiifolia. Nobody knew that time the existence of a close related species from West Sumatra: C. moehlmannii. Herbarium material of this species was labeled as C. pontederiifolia. Rataj found an inflorescence in it but he did not recognize it as new.
When Jacobsen (1982) discovered an immature spathe in the holotype of C. pontederiifolia which proved to be the same as that from 'C. sulphurea' , so it was clear that the latter has to be regarded as a synonym. Some years later De Wit described C. moehlmannii based on cultivated material.

In the past decade much more plants were found in Sumatra showing the variation in the spathe of C. pontederiifolia. You see an almost continuous series from bright yellow to purple red, the latter named C. moehlmannii

Both species, C. pontederiifolia and C. moehlmannii are excellent aquarium plants and grow very well in a simple tank.

Note. Rataj (1975) described a new species: C bogneri, which too has a bright yellow limb of the spathe. In some early articles both species are interchanged.
