Crinum thaianum, common name Thai onion plant or water onion, is an emergent plant species endemic to coastal plain of southern Thailand in Ranong and Phang Nga Provinces. Its natural habitat is along the banks of running streams, where its roots and bulb are submerged but the flowering holds the umbel of large, showy flowers above the surface. This natural habits make it a wonderful addition for tropical aquaria, and it is sold in many lands to be used in decorating displays of tropical fish. In nature, however, the species is threatened and diminishing in numbers due to habitat destruction.

Aponogeton lakhonensis is a species of an aquatic genus Aponogeton, itself the only genus in the Aponogetonaceae family. This species with a yellow-flowered single spike rising above the water, is found in ricefields, ponds and slow-moving streams of tropical and sub-tropical Asia. An outlier population occurs in Sulawesi, the main area of occurrence is from Thailand to Zhōngguó/China and Assam in India. It is more closely related to tropical Australian species of Aponogeton than it is to other Southeast Asian species. In Thailand the whole plant is eaten is salads, whereas Cambodians prefer the leaves alone served with fish sauce.

Aponogeton ranunculiflorus, the Sehlabathebe water lily, is a tiny and endangered species of aquatic plant, that belongs to the pondweed family Aponogetonaceae. It is protected in the Sehlabathebe National Park in the mountains of Lesotho, where it is very localized, and nearby in the uKhahlamba / Drakensberg Park of KwaZulu-Natal, South Africa. Outside these areas it is seriously threatened. It is found in sandstone rock pools, up to 7 metres deep, and in permanently wet tarns or sensitive high altitude mires, at altitudes between about 2,600 and 3,200 metres. Its spiralled stems allow the flowers to remain at surface level. Threats to the species include overgrazing and trampling by cattle, overburning, erosion and subsistence farming. Their small (1 cm) corms can survive the drying out of the pools, or being frozen into the muddy bottoms.
