Euryops walterorum is a species of plant in the family Asteraceae that is endemic to Namibia.
The first herbarium specimens of E. walterorum were collected in 1891, but it would not be formally described until 1955. Hermann Merxmüller named this new species in honour of German botanists Erna and Heinrich Walter. [2]
E. walterorum is known only from the summit plateau of Gamsberg Mountain, where it grows in clay soils at altitudes of 2,000–2,334 m (6,562–7,657 ft). [3] It grows in the shrublands along the northern, eastern, and southern parts of the plateau, but is not found in the central grasslands. [2]
E. walterorum is an erect shrub growing to 2 m (6 ft 7 in) tall. The stems are covered with brownish or grey bark and are mostly hairless. The stiff, leathery leaves are broadly lanceolate to ovate or obovate in shape and measure 10–15 mm (0.39–0.59 in) by 5–7 mm (0.20–0.28 in). Conspicuous hairs give the leaves a rough texture. The flower heads are bowl shaped, lacking ray florets, and measure 4–9 mm (0.16–0.35 in) in diameter. [3]
A 2004 assessment for the International Union for the Conservation of Nature's Red List categorised E. walterorum as least concern. [1] However, a 2021 paper reassessing the species assigned a preliminary status of critically endangered under criteria B1ab(iii,iv) and B2ab(iii,v), based on the small area of occupancy, small number of locations at which this species is present, the continuing decline in habitat quality, and the continuing decline in the number of mature individuals within the population.

Hesperocyparis bakeri, previously known Cupressus bakeri, with the common names Baker cypress, Modoc cypress, or Siskiyou cypress, is a rare species of western cypress tree endemic to a small area across far northern California and extreme southwestern Oregon, in the western United States.
Nepenthes glabrata is a tropical pitcher plant endemic to Sulawesi. The species grows in open, high forest at elevations of 1600 to 2100 m. It produces dainty, colourful pitchers reaching only a few centimetres in height. These traps are red speckled on a yellowish background, giving them a "hand painted" appearance.
Eucalyptus tereticornis, commonly known as forest red gum, blue gum or red irongum, is a species of tree that is native to eastern Australia and southern New Guinea. It has smooth bark, lance-shaped to curved adult leaves, flower buds in groups of seven, nine or eleven, white flowers and hemispherical fruit.
Felicia gunillae is a species of plant in the family Asteraceae that is endemic to Namibia.
Normanbya is a monotypic genus of palms containing the single species Normanbya normanbyi, which is known by the common name black palm It is endemic to Queensland, Australia and is threatened by habitat destruction.
Aloe viridiflora is a species of plant in the genus Aloe. The species is endemic to Namibia with a wide range and is known from at least six different populations. Current trends are not known and the species is listed as LC on the IUCN Red List. However, it is scarce and Namibian authorities consider it threatened; the plant must not be removed or disturbed. It is the only known green-flowering aloe. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and rocky areas. It can produce hallucinations when ingested, leading to its occasional use in shamanic rituals.
Juttadinteria deserticola is a species of plant in the family Aizoaceae that is native to Namibia and South Africa.

Tridentea pachyrrhiza is a species of plant in the family Apocynaceae that is native to Namibia and South Africa.
Grevillea australis, commonly known as alpine grevillea or southern grevillea, is a species of flowering plant in the family Proteaceae and is endemic to south-eastern Australia. It is a spreading to prostrate shrub with simple, narrowly egg-shaped leaves and groups of white to pale pink flowers with a glabrous ovary.
Grevillea ilicifolia, commonly known as holly grevillea or holly bush, is a species of flowering plant in the family Proteaceae and is endemic to southern continental Australia. It is a spreading to prostrate shrub with holly-like leaves with sharply-pointed triangular to egg-shaped teeth or lobes, and clusters of green to cream-coloured and mauve flowers with a pink to red style.
Grevillea angustiloba, commonly known as dissected holly-leaf grevillea, is a species of flowering plant in the family Proteaceae, endemic to southern continental Australia. It is a prostrate, low-lying or erect shrub with deeply divided pinnate leaves and usually red, sometimes orange or pale yellow flowers.
Grevillea huegelii, commonly known as comb spider-flower or comb grevillea, is a species of flowering plant in the family Proteaceae and is endemic to southern continental Australia. It is an erect to low-lying shrub with divided leaves with mostly three to eleven sharply-pointed linear lobes, and clusters of red to pink flowers that are silky-hairy on the outside.
Aloe pearsonii is a very distinctive and unusual species of aloe, that is naturally endemic to the arid Richtersveld area on the border between South Africa and Namibia.
Lithops francisci, commonly known as one of the living stones or pebble plants, is in the family Aizoaceae. It is endemic to the arid desert environments of Namibia. It is a succulent with a natural habitat in rocky areas. L. francisci was assessed by Nicholas Edward Brown in 1925. It is one of the Lithops plants and shares the characteristic bi-leaf head pattern separated by a deep fissure, the bottom of which houses and protects the stunted stem.
Grevillea albiflora, commonly known as white spider flower, is a species of flowering plant in the family Proteaceae and is endemic to inland eastern Australia. It is a shrub or small tree with pinnatisect leaves with linear lobes, and white to creamy-green flowers.
