Cryptocoryne affinis   Hooker f

Cryptocoryne affinis is one of the 'classical' aquarium plants, the first reports go back to 1939 when the firm Haertel in Dresden, Germany, imported this new plant. In the 50s this plant became enormous popular at aquarists under the name C. haerteliana. During the 50s it turned out that this plant was already described as C. affinis. The mistake is easy to understand because probably nobody looked for it and maybe also because most herbarium specimens of the latter were from emersed growing plants, which are much smaller that the submersed grown plants.
In the past decades, plants from many localities in West Malaysia were collected, all a bit different. Some more brownish, others more bullated. However the 'classical' haerteliana with the pale veins, a deep green upper side and a wine red lower side is not found yet, but is still in cultivation. Now for more than 70 years!

The 'classical' C. affinis in the aquarium with almost smooth, tall, green leaves.The upper side of the leaves may be dark velvet green with a pale midrib, the lower side deep purple. Spathe up to 40 cm with many turns.

This giant leaved C. affinis popped up in Switzerland. With its bullated leaves it strongly resembles C. usteriana but it proved to be a real C. affinis.

The giant leaved C. affinis in emersed cultivation. The leaves can be brownish and are relative big for an emersed grown C. affinis. All emersed grown plants are strongly bullate.

Habitat of C. affinis

A stream near Jerantut in Pahang State, W. Malaysia in September. Note the very low water level.

South of Bentang in Pahang State, West Malaysia. In May, Sungai Perdak is a ca. 10 m wide river, C. affinis grows on the bank.
coll. B 805
In the riverbed grows C. affinis fully exposed to the sun. They form dark flecks near the rapid in the shallow, cloudy water. The very small specimens grow in dense mats together with some Hydrilla and Vallisneria.

In more sheltered places C. affinis develops rather big leaves.
coll. B 805
Plants from the bank grow merely in clay. The plants are very deep rooted, the white part of the petioles were below surface.
coll. B 805
A full green specimen. In emersed culture the leaves are flat on the soil. The lower side mostly pale green with reddish veins.
coll. AZ210-6, cult. B 1357
The limb may have many turns.

The collar is hidden in the spiraled limb. Note the stark reflective cells in the throat.

When wet, the throat shows it real colour.

Cryptocoryne affinis has a wide distribution in West Malaysia. There is one collection known from the very South of Thailand.
