Detailed Traits of Purslanes

Leaf Features

Typically clustering at the stem tips and joints, they are narrow, cylindrical, and fleshy, with lengths ranging from 0.5 to 2 inches (1.3 to 5 cm). The leaves are usually bright green but may develop a reddish tinge when exposed to direct sunlight. The surface is smooth and slightly succulent, with subtle, nearly indistinguishable vein patterns.

Fruit Features

The fruit of purslanes is a small, ridged capsule, which when mature splits open to release numerous tiny seeds. The shape of the capsule is typically round to oval, and upon reaching maturity, it may exhibit a brown or tan color, providing a contrast to the plant's vibrant foliage. Its textured surface aids in the dispersal of the seed contents. Typically, the capsule measures approximately 0.2 to 0.4 inches (5 to 10 mm) in diameter, with a papery outer layer that becomes dry and brittle as it ages. The fruit's minuscule seeds are renowned for their high quantity within each capsule, ensuring the widespread propagation of purslanes.
