Introduction

• Nuphar pumila, the least water-lily[4] or small yellow pond-lily, is an aquatic perennial plant in the Nymphaeaceae family.
• It is also known as the dwarf water lily since it looks like a smaller Nuphar lutea.
• While Nuphar pumila has a star-shaped, or lobed form of the stigma disc and glabrous leaf undersides, Nuphar lutea has a round stigma disc and the undersides of its leaves are occasionally fine-haired on the midribs.
• Its flowers bloom from July to August and are typically pollinated by flies.
• Nuphar pumila flowers typically have 4–6 petals, are actinomorphic, have many stamen and range from yellow to green depending on maturity.
• Its floating leaves are large and ovate, with pinnate venation, while the submerged leaves are smaller and round; the plant also has a thick creeping rhizome.
