Euphorbia nivulia is a subtropical succulent species of flowering plant in the family Euphorbiaceae. It is found in the Indian subcontinent and is commonly known as the leafy milk hedge, holy milk hedge or dog's tongue. [1]
Euphorbia nivulia forms a small tree up to 9 m (30 ft) high and 1 m (3 ft) in girth. The bark is rough and thick. The branches are succulent, and grow out from the trunk at an obtuse angle. Spirally arranged tubercles on the branches bear clusters of sharp spines. The leaves are simple and arranged alternately, and have a very short or no stalk. The leaf blade is obovate and spoon-shaped to inverted-lance-shaped, up to 25 cm (10 in) long and 8 cm (3 in) wide. They are thick and fleshy, the tip is rounded, the base is tapered, and the margin is entire. The midrib is prominent on the underside of the leaf. The reddish cyathia (false flowers found in the genus Euphorbia ) develop in groups of three in the axils of the leaves towards the ends of the branches. The fruits are divided into three parts, the lobes being compressed laterally. The seeds are four-angled and ovoid, smooth and about 4 mm (0.16 in) long. [1] This plant is similar to Euphorbia caducifolia , leafless milk hedge, but it retains its leaves for longer than does E. caducifolia, and does not form bushy thickets. [2]
Euphorbia nivulia is native to Pakistan, India, Sri Lanka, Bangladesh and Myanmar. [3] It grows in both wet and dry deciduous forests on rocky hillsides, [4] and also in dry, barren areas; it is planted as a hedge plant in agricultural areas. [5]
Juice squeezed from the leaves, bark from the root, the stems and the latex have been used in traditional medicine. Research has shown that the plant possesses antimicrobial, wound healing, haemostatic and cytotoxic activity. Additionally, it possesses larvicidal, insecticidal and nematicidal activities, and may prove useful in controlling the mosquitoes, Aedes aegypti and Culex quinquefasciatus , and suppressing the root-knot nematode, (Meloidogyne incognita).

Peperomia is one of the two large genera of the family Piperaceae. Most of them are compact, small perennial epiphytes growing on rotten wood. More than 1500 species have been recorded, occurring in all tropical and subtropical regions of the world, though concentrated in Central America and northern South America. A limited number of species are found in Africa.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the spurge family (Euphorbiaceae). "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae, not just to members of the genus. Some euphorbias are commercially widely available, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant. Euphorbias from the deserts of Southern Africa and Madagascar have evolved physical characteristics and forms similar to cacti of North and South America, so they are often incorrectly referred to as cacti. Some are used as ornamentals in landscaping, because of beautiful or striking overall forms, and drought and heat tolerance.
Pachypodium brevicaule is a species of plant that belongs to the family Apocynaceae.
Euphorbia tithymaloides is a perennial succulent spurge. An erect shrub, the plant is also known by the scientific name Pedilanthus tithymaloides. However, the genus Pedilanthus has been submerged into the genus Euphorbia, and is more correctly known by its new name.
Euphorbia tirucalli is a tree that grows in semi-arid tropical climates. A hydrocarbon plant, it produces a poisonous latex that can cause temporary blindness.
Ziziphus nummularia, commonly known as wild jujube or jhahrberi in Hindi, is a species of Ziziphus native to the Thar Desert of western India and southeastern Pakistan, south Iran, Afghanistan, Lebanon and Zimbabwe. Ziziphus nummularia is a shrub up to 6 metres (20 ft) or more high, branching to form a thicket. The leaves are rounded like those of Ziziphus jujuba but differ from those in having a pubescence on the adaxial surface. The plant is commonly found in arid areas, hills, plains, and agricultural fields.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Mimetes arboreus, or Kogelberg pagoda, is an evergreen, upright large shrub or small tree of 2–6 m (6½–20 ft) high in the family Proteaceae. It grows from a thick trunk with a smooth grey bark that branches at ½–1 m (1½–3 ft) above the ground. It has silvery, lance-shaped, pointy leaves of 5–8¼ cm (2.0–3.3 in) long and ¾–3¼ cm (0.3–1.3 in) wide, at an upward angle and overlapping each other. The inflorescences are set just below the top of the branches, are cylinder-shaped, 8–10 cm in diameter, topped by a crest of more or less horizontal pinkish or reddish tinged leaves. It consists of several flower heads in the axils of pinkish orange leaves that form a hood shielding the underlying flower head. Each flower head contains eight to thirteen individual flowers, with bright red styles and grey silky perianth lobes. It is endemic to the Fynbos ecoregion of South Africa, being confined to the Kogelberg mountain range.

Bergenia crassifolia is a plant species in the genus Bergenia. Common names for the species include heart-leaved bergenia, heartleaf bergenia, leather bergenia, winter-blooming bergenia, elephant-ears, elephant's ears, Korean elephant-ear, badan, pigsqueak, Siberian tea, and Mongolian tea.

Mimetes fimbriifolius, also called cowl pagoda or the fringed pagoda, is a species of plant in the family Proteaceae. It is a dense, rounded, multi-branched tree that grows up to 4 metres in height. This attractive and striking plant flowers all year round, and produces red and yellow branch-heads and inflorescences. The nectar-rich flowers are pollinated by sunbirds and the seeds are distributed and taken underground by ants before germinating. It is endemic to the Table Mountain range in the city of Cape Town, South Africa.

The heads consist of mostly dark orange 4-merous flowers, from which long, identically colored styles emerge, which are directed straight down during flowering. It is called rocket pincushion or skyrocket leucospermum in English and perdekop in Afrikaans. It flowers from the end of August to December. It is an endemic species that can only be found in the southwest of South Africa.
Euphorbia royleana is a species of flowering plant in the family Euphorbiaceae. It is also known as Sullu spurge, and Royle's spurge. It is a succulent and almost cactus like in appearance although unrelated. It grows right across the Himalaya mountains from Pakistan, India, Bhutan, Myanmar, Nepal to western China, It prefers dry and rocky slopes between 1000 and 1500 meters, but has been found up to 2000 meters. Flowering and fruiting is in spring to early summer (March–July) and seeding is in June–October. It is used as a hedging plant in northern India and has medicinal uses.
Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. It is sometimes referred to as the money tree; however, Pachira aquatica also has this nickname.

From the center of the flowers emerge almost straight styles that jointly give the impression of a pincushion. It is called Piketberg pincushion in English. Flower heads can be found between late September and December. It is an endangered species, only known from three close locations in the Western Cape province of South Africa.
