Nymphaea candida is a species of perennial, aquatic,[2] rhizomatous herb[3] in the family Nymphaeaceae native to the region spanning from Europe to Siberia and Western Himalaya.[1]
Description
[edit | edit source]
Vegetative characteristics
[edit | edit source]Nymphaea candida is a perennial, aquatic,[2] rhizomatous herb[3] with unbranched,[4] 5 cm wide rhizomes.[5] The petiolate, stipulate,[3] oval to suborbicular floating leaf with an entire margin[5] and a deep basal sinus[6] is 10–30 cm long, and 25 cm wide.[5] The oblong submerged leaves have a thin lamina and short petioles.[3] The thick, terete,[3] smooth,[5] 30–100(–160) cm long petiole[7] has air canals.[3]
Generative characteristics
[edit | edit source]The bisexual,[7] actinomorphic, 5–15 cm wide flower[3] floats on the water surface.[4] The 4(–5) oblong to ovate-oblong sepals are 3.8 cm long, and 1.3 cm wide. The 12–20 white petals[5] are 3–5.5 cm long and show a gradual transition towards the stamens.[4] The petals decrease in size towards the centre of the flower.[6] The androecium consists of 32–70 stamens.[5] The gynoecium consists of 6–14 carpels.[8] The red or yellow stigmatic disk[6] is concave.[6][9][7] The green to red, ovoid to spherical, 1.9–4.4 cm wide fruit with persistent sepals bears ellipsoid, brown, arillate,[5] 4-6 mm long,[3] and 3-4 mm wide seeds.[6]
Cytology
[edit | edit source]The chromosome count is 2n = 112, 160.[4] The genome size is 1936.44 Mb.[10]
Taxonomy
[edit | edit source]The plant was described by Carl Borivoj Presl in 1882.[11][12] However, sometimes both Carl Borivoj Presl and Jan Svatopluk Presl are credited as the taxon authors.[2][3] Within the subgenus Nymphaea subg. Nymphaea it is placed in the section Nymphaea sect. Nymphaea.[13]
Etymology
[edit | edit source]The specific epithet candida from the Latin candidus means pure white.[14]
Distribution and habitat
[edit | edit source]It grows in the quiet freshwaters in Eurasia. The plant grows only in water, as it is an aquatic plant, mainly in ponds, lakes, and slow flowing streams.[15]
Conservation
[edit | edit source]It is endangered in China,[2] and Germany.[16]
Use
[edit | edit source]It is cultivated as an ornamental plant in water gardens.[9][17]
