Oedera squarrosa ("Vierkant-perdekaroo") is a prickly shrublet belonging to the family Asteraceae.
It is an abundant and common species in the southwestern Cape Provinces of South Africa (Namaqualand to Port Elizabeth). It is most commonly found in close proximity to the main mountain ranges, especially in rocky loamy or clayey soils.
Oedera squarrosa is a small, erect shrublet (60cm high). The leaves are small (15mm x 7mm), ovate, glandular and down-curved, with thickened margins, and grow densely packed along the stems. On the younger stems, the leaves are usually in four ranks. Older stems often have a more imbricate arrangement.
Tufts of a couple of yellow flowerheads appear at the tips of the branches in Spring and Summer. They are 10mm wide, with relatively short stalks (2-10mm).
Oedera squarrosa is closely related to Oedera genistifolia , another widespread species that is found on lower (usually north-facing) slopes of shale, sandstone or limestone. However, O. squarrosa has wider leaves (7 mm) that are more recurved or down-turned. [1]
Elodea canadensis is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
Searsia lucida, previously known as Rhus lucida, and commonly known as the varnished kuni-rhus (English) or blinktaaibos (Afrikaans).
Hypericum tortuosum is a species of flowering plant in the genus Hypericum. It is found only in Socotra, Yemen, where it is endemic. The species is an apomorphic relative of the other Socotran species in Hypericum sect. Triadenioides and is most closely related to Hypericum scopulorum. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Aloe squarrosa is a species of flowering plant in the Asphodelaceae family. It is from the island of Socotra, Yemen.
Felicia aethiopica is a low shrublet of up to about 50 cm high that is assigned to the family Asteraceae. It has rigid, leathery, inverted egg-shaped leaves, with only the lowest pair set oppositely. It has flower heads with an involucre of about 8 mm in diameter with bracts that each contain three resin ducts, and have one whorl of twelve to fourteen ray florets with about 11 mm long and 1½ mm wide blue straps surrounding many yellow disc florets. The plant is called wild aster or dwarf Felicia in English, and wilde-aster or bloublombossie in Afrikaans. Flowering occurs year-round. Wild aster can be found in the Western and Eastern Cape provinces of South Africa.
Gorteria is a genus of small annual herbaceous plants or shrubs, with 8 known species, that is assigned to the daisy family. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and are surrounded by an involucre, consisting of in this case several whorls of bracts, which are merged at their base. In Gorteria, the centre of the head is taken by relatively few bisexual and sometimes also male, yellow to orange disc florets, and is surrounded by one complete whorl of 5–14 infertile cream to dark orange ray florets, sometimes with a few ray florets nearer to the centre. None, some or all of them may have darker spots at their base. The fruits remain attached to their common base when ripe, and it is the entire head that breaks free from the plant. One or few seeds germinate inside the flower head which can be found at the foot of plants during their first year. The species flower between August and October, except for G. warmbadica that blooms mostly in May and June. The species of the genus Gorteria can be found in Namibia and South Africa.
Munroa squarrosa is a species of grass known by the common name false buffalograss. It is native to North America from central Canada to Chihuahua in Mexico. It can be found in many types of dry, open habitat, including disturbed areas.
Pholiota squarrosa, commonly known as the shaggy scalycap, the shaggy Pholiota, or the scaly Pholiota, is a species of mushroom in the family Strophariaceae. Common in North America and Europe, it is a secondary parasite, in that it attacks trees that have already been weakened from prior injury or infection by bacteria or other fungi. It has a wide range of hosts among deciduous trees, although it can also infect conifers. It can also live as a saprobe, deriving nutrients from decomposing wood.
Ipomoea lacunosa, the whitestar, white morning-glory or pitted morning-glory, is a species that belongs to the genus Ipomoea. In this genus most members are commonly referred to as "morning glories". The name for the genus, Ipomoea, has root in the Greek words ips and homoios, which translates to worm-like. This is a reference to the plant's vine-like growth. Lacunosa comes from a Latin word meaning air spaces, correlating with the venation of the leaves. Ipomoea lacunosa is native to the United States and grows annually. The flowers of this species are usually white and smaller than most other morning glories.
Microloma is a small genus of Ceropegia-like twiners and twiggy bushes occurring in mainly arid or fynbos regions in South Africa. They are generally nondescript when not in bloom, but the flowers of most species are incongruously decorative.
Hazardia rosarica is a species of flowering shrub in the family Asteraceae commonly known as the El Rosario goldenbush. Hazardia rosarica is a fragrant shrub characterized by its zigzagged branches, toothed glutinous leaves, and yellow flower heads of only disc flowers. This species is endemic to Mexico and is only found in the region near of the town of El Rosario in Baja California. It is usually found on north and east facing slopes and ridgetops close to the coast.
Beaufortia squarrosa, commonly known as sand bottlebrush, is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to the southwest of Western Australia. The Noongar peoples know the plant as buno. It is sometimes a dense shrub, others straggling with 4 neat rows of small, oval leaves along the stems, and heads of red, orange or yellow flowers in the warmer months.
Oedera capensis is a prickly shrublet belonging to the family Asteraceae. It has stems that branch only at the foot and are densely set over their entire length with narrowly triangular leathery leaves with a sharp tip at approximately right angles to the stem. At their tip are what at first sight appears to be a single flowerhead with yellow ray florets and yellow disc florets. In fact, these are mostly nine densely cropped heads, as is suggested by the nine domes of the "disc" of the composite head, the untidy arrangement of the ray florets, and becomes very clear when cutting through the composite head. It is an endemic of the south of the Western Cape province in South Africa.
Dracaena braunii is a species of flowering plant in the family Asparagaceae. It was named after the German collector Braun, Johannes M. (1859–1893). Most plants named Dracaena braunii in cultivation are Dracaena sanderiana, a plant with flowers five times longer than those of D. braunii, while the leaf base is not congested as in D. braunii.
Oedera genistifolia is a prickly shrublet belonging to the family Asteraceae.
Oedera imbricata is a prickly shrublet belonging to the family Asteraceae.
Oedera uniflora ("Kalksteenperdekaroo") is a prickly shrublet belonging to the family Asteraceae.
Hypericum heterophyllum is a flowering plant in the Hypericaceae family and is the only species in Hypericum sect. Heterophylla.
Selago thomii is a species of plant in the family Scrophulariaceae. It is endemic to the Western Cape, South Africa.
