Description[edit]
Vegetative characteristics[edit]
Nymphaea loriana has branching, 2 cm wide rhizomes. The membranous submerged leaves are 8-10 cm long, and 8-12 cm wide. The suborbicular to ovate-elliptic, 10–21 cm long, and 8-18 cm wide floating leaves have a papery texture. The adaxial leaf surface is green, and the abaxial leaf surface is bright green with occasional purple colouration.[4]
Generative characteristics[edit]
The 7.5–10 cm wide flowers have four sepals, and 12–21 petals. The androecium consists of 33–48 yellow stamens. The gynoecium consists of 8–11 carpels. The 2-2.5 cm wide fruits with coiled peduncles bear 3.5-4 mm long, 2.5-3 mm wide, arillate, greenish-brown, ovoid, smooth seeds.[4]
Reproduction[edit]
Generative reproduction[edit]
Despite being of hybrid origin, Nymphaea loriana is fertile.[4]
