Frithia is a genus of succulent plants in the family Aizoaceae, indigenous to several small rocky areas in the vicinity of Gauteng Province, South Africa.
Like several of its close relatives (e.g. Fenestraria ) and other plants in its ecotype (e.g. some species of Haworthia and Bulbine ) it has epidermal windows (translucent areas in its leaves) as an adaptation to the difficulties of photosynthesis in its arid environment.
Frithia are summer-growing species, as their natural habitat lies in a summer-rainfall region. They grow in very well-drained, sandy soil, with repetitive light watering in summer and a dry environment in winter.
The genus contains the following species:

Grevillea, commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds.
Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος, meaning "stone," and ὄψ, meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Ancient Greek "-ops" means that even a single plant is called a Lithops.
Persoonia, commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus Persoonia are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe.
Xylomelum is a genus of six species of flowering plants, often commonly known as woody pears, in the family Proteaceae and are endemic to Australia. Plants in this genus are tall shrubs or small trees with leaves arranged in opposite pairs, relatively small flowers arranged in spike-like groups, and the fruit a woody, more or less pear-shaped follicle.
Banksia ilicifolia, commonly known as holly-leaved banksia, is a tree in the family Proteaceae. Endemic to southwest Western Australia, it belongs to Banksia subg. Isostylis, a subgenus of three closely related Banksia species with inflorescences that are dome-shaped heads rather than characteristic Banksia flower spikes. It is generally a tree up to 10 metres (33 ft) tall with a columnar or irregular habit. Both the scientific and common names arise from the similarity of its foliage to that of the English holly Ilex aquifolium; the glossy green leaves generally have very prickly serrated margins, although some plants lack toothed leaves. The inflorescences are initially yellow but become red-tinged with maturity; this acts as a signal to alert birds that the flowers have opened and nectar is available.
Watsonia is a genus of plants in the family Iridaceae, subfamily Crocoideae. Watsonias are native to southern Africa. The genus is named after Sir William Watson, an 18th-century British botanist.
Banksia verticillata, commonly known as granite banksia or Albany banksia, is a species of shrub or (rarely) tree of the genus Banksia in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to 3 m (10 ft) in height. It can grow taller to 5 m (16 ft) in sheltered areas, and much smaller in more exposed areas. This species has elliptic green leaves and large, bright golden yellow inflorescences or flower spikes, appearing in summer and autumn. The New Holland honeyeater is the most prominent pollinator, although several other species of honeyeater, as well as bees, visit the flower spikes.
Fenestraria is a genus of succulent plants in the family Aizoaceae, native to the Namaqualand in Namibia.
Curio rowleyanus, syn. Senecio rowleyanus, is a flowering plant in the daisy family Asteraceae. It is a creeping, perennial, succulent vine native to the drier parts of southwest Africa. In its natural environment its stems trail on the ground, rooting where they touch and forming dense mats. It often avoids direct sunlight by growing in the shade of other plants and rocks. It is commonly known as string-of-pearls or string-of-beads.
Grevillea speciosa, also known as red spider flower, is a shrub which is endemic to New South Wales in Australia.
Stirlingia latifolia, commonly known as blueboy, is a plant endemic to Western Australia.
Bellendena montana, commonly known as mountain rocket, is a species of low-growing multi-stemmed shrub in the plant family Proteaceae. It is endemic to high-altitude subalpine and alpine regions in Tasmania, Australia. The prominent white flower spikes appear over summer, followed by small bright red or yellow fruit in late summer and autumn.
Cryptostegia is a genus of flowering plants native to tropical Africa and Madagascar. The genus is in the family Apocynaceae.
Grevillea johnsonii, commonly known as Johnson's grevillea or Johnson's spider flower, is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is a shrub with divided, needle-like leaves and red to orange flowers, and grows in rocky places.
Persoonia levis, commonly known as the broad-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 5 m (16 ft) in height and has dark grey papery bark and bright green asymmetrical sickle-shaped leaves up to 14 cm (5.5 in) long and 8 cm (3.2 in) wide. The small yellow flowers appear in summer and autumn, followed by small green fleshy fruit, which are classified as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. levis interbreeds with several other species where they grow together.
Grevillea ilicifolia, commonly known as holly grevillea, is a species of the plant genus Grevillea. It is a shrub of variable form, growing to between 0.3 and 2 metres in height and 3 metres wide. Typically, leaves are lobed and holly like, but may also be unlobed. The flowers have perianths that have a base that is cream to green grading to grey-mauve. Styles may be pink, red, orange or yellow. The main flowering period in the species' native range is September to November.
Conophytum jucundum is a species of succulent plants belonging to the family Aizoaceae. As its synonym Conophytum gratum, the pleasing cone plant, it has gained the Royal Horticultural Society's Award of Garden Merit.
Leaf window, also known as epidermal window, and fenestration. is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur. The translucent structure may include epidermal tissue, and in some succulent plants it consists of several cell layers of parenchyma, which may also function as water-storage tissue. It can appear as a large continuous patch, a variegated or reticulated region, or as numerous small spots. Is found in some succulent plants native to arid climates, allowing much of the plant to remain beneath the soil surface where it is protected from desiccation by winds and heat while optimizing light absorption. Many species featuring leaf windows are native to Southern Africa.
Paranomus tomentosus, the hairy-leaf tree sceptre, is a flower-bearing shrub that belongs to the genus Paranomus and forms part of the fynbos. The plant is native to the Western Cape, South Africa.
