Cryptocoryne parva de Wit

Cryptocoryne parva grows in the central highlands of Sri Lanka near Kandy. It is collected in the recent years only a very few times and must perhaps be regarded as a threatened species!

Distribution of C. parva on Sri Lanka
       

Cryptocoryne parva is the smallest Crypt, known until now. The leaves mostly not exceeding 6 cm. The spathe is about 1.5 cm. The leaves are grass-green without any purple. However this species is quite easy to cultivate, it is seldom seen in aquaria. It is an excellent plant for the foreground of a normal aquarium, growing not too fast, so reducing maintenance.
Already in 1928, Petch, who was director of the Botanical Gardens of Peredeniya (Sri Lanka), published in his Notes on Cryptocoryne a drawing of this species, which he regarded to be a C. nevillii (see more on this topic under C. x willisii). De Wit described it as Cryptocoryne parva in 1970.
Cryptocoryne parva grows in the central highlands of Sri Lanka near Kandy. It is collected in the recent years only a very few times and must perhaps be regarded as a threatened species!
