Nymphaea candida J. Presl is a species of aquatic perennial herbaceous plants in the genus Nymphaea native to quiet freshwater habitats in Eurasia, it is in flower from July to August. It is sometimes treated as a subspecies of N. alba (N. alba L. subsp. candida (J. Presl) Korsh.)
Nymphaea Candida is an aquatic perennial herb that is laticiferous and rooted. It has a spread of approximately 60 cm and a plant depth from 10–30 cm. It has rhizomes that are stoloniferous and unbranched. There are about 10-20 leaves that are 9–19 cm across that are usually floating or submerged. The leaves are membranous when young and they are prominently veined when mature. The plant prefers growing in water-depths of about 60–80 cm. Nymphaea Candida is a small white flower (10–20 cm across) with a yellow center. The flower is bisexual and it is usually floating alone. The penducles are long and there are 4 sepals.

Distribution and habitat
It grows in the quiet freshwaters in Eurasia. It only grows in water from July to August.
The plant grows only in water, as it is an aquatic plant, mainly in ponds, lakes, and slow flowing streams.
The rhizome is used as an anodyne, antiscrofulatic, astringent, cardiotonic, demulcent and sedative. If used in combination with slippery elm (Ulmus rubra) or flax (Linum usitatissimum), it has been used to make a poultice that treats boils and abscesses. As for the flowers, they are an anaphrodisiac and sedative. The complete cure of uterine cancer by a decoction and uterine injection has been recorded.
