Cryptocoryne parva is the smallest of all Cryptocorynes. It is one of the few species that does not significantly change its leaf shape and colour depending on cultivation conditions. It needs more light than most other Cryptocorynes because it almost loses its leaf blade under water. So it must never be overshadowed by other plants. Individual plants should be planted a few centimetres apart, and after about six months they will form a cohesive low group of plants. Recommended for foreground planting.

Cryptocoryne pontederiifolia can form slightly pink leaves under water, and in good growing conditions it grows very large. It has characteristically horizontal leaves on a long leaf stem. It rarely suffers from so-called cryptocoryne disease.

"For some time Tropica has been selling a plant known as “Pellia”, which has now been renamed Monosolenium tenerum. When plant names change, it usually means that botanists have discovered that they are not in fact dealing with the plant they thought they were, or, more seldom, that two botanists have independently discovered and named the same plant. In the latter situation, the first name to be announced is always the one which applies. Spelling errors are a different matter, and may be repeated so many times that the correct spelling is only discovered when someone refers to the original description. In the present case, several factors have contributed, and there are spelling mistakes in both the old and the new name.
