Cryptocoryne ciliata (Roxburgh) Schott var. ciliata

Cryptocoryne ciliata is a species that grows from India to Papua New Guinea in the fresh to brackish water tidal zone. There is little known about the variation through that range. Two varieties are distinguished, var. ciliata with a chromosome number of 2n = 22, more narrow leaves and long overground runners and var. latifolia with broad leaves and with typical short shoots in the axils, having a chromosome number 2n = 33. The latter is sterile. The narrow / broad leaf character may be not firm. The distribution of the var.'s is not well known, at several places also mixed populations are found. The highly developed embryos in var. ciliata are also known from Cryptocoryne versteegii.

In the 1961 van Liet, Amsterdam, imported fruiting specimen of C. ciliata var. cilata. This seed show the typical sack with the 'plumila' inside.

When the sack opens, the 'plumila' spread. When the seed is released it will drift away with the tidal current, the 'plumila' probably for anchoring.

No C. ciliata made the crossing to Australia, nor is it known from the Philippines.
       

Cryptocoryne ciliata is easy to cultivate in emerged culture in a simple mixture of sand and peat litter with artifical fertilisation.. Both var.'s propagate rather quick. They can be grown in relative dry air, in full sun, but they are sensitive for cold: in an open pot behind a cold window will not go for long.
Their dry-air tolerance makes them well suited for time-lapse photography. See the movie of the opening of the limb of the spathe
