C.
spiralis var. cognatoides grows deeply buried in the soil (the white parts of the petiole). Note the strong contractile roots.

C.
spiralis var. cognatoides grows easy and flowers frequent in cultivation. A dormant phase is never obeserved. The spathe easily reach a length of ca 30 cm.

The plant does not make runners. After a 15 year period in cultivation, it was only recently that the rhizome thrived two new plants. By that reason it is one of the most rare Cryptocoryne in cultivation.

The spathe with the typical denticulation along the margin is with it kettle 2 - 3 cm deep in the ground.

The lower part of the limb has transverse ridges inside, mostly reddish. Note the very long spadix and the constriction in the upper part of the kettle.

Note the
typical septum, a transverse wall with a hole between the kettle and the limb. Apparently there is no tube, as usual in Cryptocoryne.

When the male flowers are removed, one can clearly see the alveoli in the wall of the kettle.

There is no favour for a left of right handed twist. Even for the same plant (as usual in Cryptocoryne).

The female flowers at the bottom of the kettle have more or less lobed stigmas.

The fruit is almost a perfect sfere. At ripening the peduncle elongates and brings the fruit above the surface. Artificial pollination.
