Acrodon N.E. Brown 1927
Name: Greek akros = point + odus = tooth, referring to the toothed leaves.

These plants form mats of disorganised rosettes of fleshy dark green leaves with a triangular crossection and rows of small teeth along their edges and keels. The large solitary flowers are on long stalks. Their petals have a darker stripe along their middle.
All four species are native to coastal South-Western and South-Eastern Cape provinces of South Africa. They are hardy on well-drained sandy soils.
|
 |
Acrodon bellidiflorus N.E. Brown 1927
This is the type species for the genus. The large flowers are pale pink with a dark pink stripe along the middle of the petals and a central mass of pink staminodes surrounding the stamens.
Native to coastal South Africa where it receives both Summer and Winter rainfall.
|
|
Name: Aloe + Greek opsis = appearance, resembles

This genus include 16 species of creeping rosulate succulents from Winter rainfall areas of the Eastern, Western and Northern Cape Provinces of South Africa. The roots are thick and in some species (e.g. Aloinopsis schooneesii) form a tuber which may be raised for display.
|
 |
Aloinopsis luckhoffii L. Bolus 1958 Syn. Aloinopsis setifera L. Bolus 1958
This plant forms a cluster of rosettes formed from fat, triangular leaves with tiny white pustules or teeth on their surfaces. Flowers are bright yellow, around an inch in diameter.
Native to limestone slopes of the central Karoo of South Africa, experiencing small amounts of Winter rainfall. Leaves become bronzed in full sun. In captivity, plants tend to become green and flabby.
|
|
Name: Greek antimimos = imitating, as the first species described resembled Argyroderma.

A large genus with 99 species of compact mat and cushion-forming Mesembs from Namibia and South Africa. Most species were moved into this genus from Ruschia which they closely resemble and the genus is now somewhat heterogeneous in form. Antimima are mainly differentiated from Ruschia by the structure of their bowl-shaped fruits which have 5 locules and large closing bodies. The valves expand with the help of broad, irregularly-lobed expanding keels.
The small leaves have a triangular cross section, typically with roughened surfaces covered in wax. However, some species exhibit differentiation in leaf form with lower leaves forming a sheaf around the base of the later pair. The pink or purple or occasionally white flowers have a central cone of filamentous staminodes surrounding the yellow stamens.

Aptenia cordifolia Schwantes 1928
A prostrate creeping plant with fibrous roots and 4-angled stems bearing small, waxy, heart-shaped leaves with bladder cells which catch the sun. The small flowers are pink.
Many cultivated plants are hybrids (A. cordifolia x A. hackeliana) with narrower leaves than Aptenia cordifolia and red flowers like those of the variegated cultivar illustrated.
Aptenia cordifolia is native to coastal plains of the Eastern Cape of South Africa, where it tolerates sea spray, and KwaZulu-Natal. Aptenia cordifolia is a traditional medicinal plant said to have anti-inflammatory properites and used to dress wounds.
This prostrate creeper spreads as ground cover, often in light shade.
In a sunny, well-drained position it may even survive the British Winter. Aptenia cordifolia has become naturalised in many temperate countries and in some is regarded as an invasive weed.

Conophytum N.E. Brown 1922 (Afrikaans: knopies = buttons)
Name: Latin conos = cone + phytum = plant

This genus consists of 88 species, with many synonyms, of dwarf succulent plants with a single fleshy body composed of two leaves partly or entirely fused along their centres. Depending on the degree of fusion plants may have a bilobed or spherical appearance. The upper leaf surface may have transluscent windows and may be smooth, rough or pubescent. The leaf colour varies from blue-green through green to brown and red. Some species of Conophytum produce many stems and leaf pairs, forming a compact cushion while others are solitary. Stems may develop two leaf pairs when overwatered in captivity or following heavy rain in their habitat. However, it is more usual for the older leaf pair to shrivel and form a membrane around the developing second leaf pair. Flowers are white to yellow, orange, pink, and purple.
Native to central and Western South African and Namibia. This free-flowering genus is popular among collectors of succulent plants as a substantial collection can be housed in a small area. Selected forms have been developed, especially in Japan, to emphasise particular charactristics of a plant e.g. squareness. Conophytums are mainly Winter growers but watering can be started in mid-Summer.
