Locally common in clear running fresh water, opened stream, a few centimeters to two meters depth depending on the seasonal water level.
Notes: According to Schulze (1972), the species is one of the four true aquatic species in Crinum, two of which are from the tropical Africa (C. aquaticum. & C. natans) and one is from Brazil and West Indies (C. purpurascens). T is has been exported to many countries and is grown successfully in the tropical aquaria. However, the species has a very restricted distribution with specific condition, the natural resources should be reserved as a special protected area. Last updated on 15 November 2016. | |
