"Cryptocoryne purpurea (Purple Water Trumpet) is a beautiful plant that can only be found hidden in the deep swampy waters of Tasek Bera, Malaysia. It had lain submerged in the lake's water, undiscovered until Professor Niels Jacobsen from the Royal Veterinary and Agricultural University, Denmark, stumbled upon it in 1985 during one of his field visits to Pos Iskandar, Tasek Bera. No sooner had it been identified and documented, the Purple Water Trumpet once again returned to obscurity."
I am quoting from the Ramsar Convention on Wetland website. The site describes the project that is underway to save this plant from extinction because of a loss of its native habitat.
It is important for us as hobbyists to start thinking about helping to save some of these species. How? Tissue culture? Emersed culture?
