Disphyma Explained

Disphyma is a genus of flowering plants in the family Aizoaceae that are native to New Zealand, Australia and southern Africa. Plants in this genus are prostrate, annual or short-lived perennial shrubs with succulent leaves and daisy-like flowers arranged singly on the ends of shoots with petal-like staminodes, many stamens and usually five styles.

Description

Plants in the genus Disphyma are prostrate, annual plants or short-lived perennials with branches that root at nodes. The leaves are arranged alternately and fused at the base, succulent and round to more or less triangular in cross-section. The flowers are usually arranged singly, sometimes in pairs or three, on the ends of branches or on short side shoots, each flower on a pedicel up to long. The perianth is tube-shaped with five sepals, two larger and leaf-like and three smaller, slightly succulent and not leaf-like. There are many petal-like, purplish staminodes in two rows and many stamens in four or five rows. The ovary is inferior and there are usually five styles. The fruit is a capsule.[1] [2]
