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 100 mm (3.9 in) 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]

Taxonomy

The genus Disphyma was first formally described in 1925 by N. E. Brown in The Gardeners' Chronicle . [3] [4]

As at October 2020, Plants of the World Online accepts four species:

Plants of the World Online also accepts two subspecies:

<i>Leptospermum</i> Genus of shrubs

Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of Melaleuca. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule.

Aizoaceae Family of dicotyledonous flowering plants

The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly succulent species that resemble stones are sometimes called mesembs.

<i>Myoporum</i> Genus of flowering plants

Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae. There are 30 species in the genus, eighteen of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands. They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.

<i>Mesembryanthemum</i> Genus of plants

Mesembryanthemum is a genus of flowering plants in the family Aizoaceae; like many members of this family, it is characterized by long-lasting flower heads. Flowers of Mesembryanthemum protect their gametes from night-time dews or frosts but open in sunlight. There is an obvious evolutionary advantage to doing this; where sun, dew, frost, wind or predators are likely to damage exposed reproductive organs, closing may be advantageous during times when flowers are unlikely to attract pollinators. It is indigenous to southern Africa.

<i>Aptenia</i> Genus of succulents

Aptenia is a small genus of flowering plants in the family Aizoaceae. They are native to southern Africa. The genus name is from the Greek a- (not) and ptenos (winged), and refers to the wingless fruit capsules.
