Cryptocoryne ciliata (Roxburgh) Schott var. latifolia Rataj

As the name says, this C. cilata has (big,) broad leaves. This character doesn't hold so much as var. cilata may have even broader leaves. Besides the name, the plant is clearly distinguished from var. cilata by having short upright sprouts, and being sterile, caused by its triploid chromosome number of 2n = 33. The distribution of both var's is not well known, at some places there are mixed populations.
