Dorstenia foetida, also known as grendelion, is a succulent plant in the genus Dorstenia , which is native to Eastern Africa and Arabia. [2] It is a very variable species with a wide distribution. [3]
A very variable species especially in shape and size of leaves, and length of petioles and stipules. It is a perennial, evergreen or caducous sub-shrub. Stem succulent, may be branched or not. Stem a thick, dark green- to mahogany-colored conical trunk, up to 15 centimeters in diameter and 30–40 centimeters in height, older parts often with peeling bark. The stem bears conspicuous and prominent round scars of petioles, inflorescences and stipules in a spiral pattern. Branches nearly as thick as the stem, up to 1–1.5 cm thick and up to 15 cm tall, with pronounced markings of leaf-, inflorescence- and stipule-scars. Leaves alternate, crowded at the top of stems and branches; stipules subulate from a broad base, 1–2 mm long, mostly long persistent; petiole 1–3.6 cm long, puberulous; blade lanceolate to ovate, obovate or elliptic, 1.8–18 x 1–2.5 cm, cuneate to rounded at the base, rounded, obtuse or acuminate at the apex, with entire, crenulate, crisp or denticulate margins, scabridulous above, sparsely puberulous below. Flower structures grayish or green (or orange/pinkish). Receptacles 1–3 together in the leaf axils, on peduncles 1–6 cm long, circular in outline, 0.6–1.5 cm in diam. (excl. appendages), appendages 7–10, linear, up to 1.5 cm long. Male flowers numerous, tepals 2, stamens 2, rudimentary ovary inconspicuous. Female flowers numerous, scattered on the upper surface of the receptacle, stigma unbranched. Fruit with elongated, minutely tuberculate, pale brown endocarp, 1–1.4 mm long. The seed pods sunk in the receptacles open explosively when ripe and send the seed flying a considerable distance. [4] [5]
Ethiopia, Somalia, Kenya, Tanzania, Saudi Arabia, Yemen and Oman.
Deciduous and succulent bushland, open places, and on rock outcrops.
In Oman the tubers of Dorstenia foetida are cooked and eaten. [6]
Cussonia is a genus of plants of the family Araliaceae, which is native to the Afrotropics. It originated in Africa and has its center of distribution in South Africa and the Mascarene Islands. Due to their striking habit, they are a conspicuous and easily recognizable group of plants. Their genus name commemorates the botanist Pierre Cusson. The Afro-Malagasy and Asian Schefflera, and Afrotropical Seemannaralia genera are related taxa that share several of its morphological characteristics, among which the leaves borne on the end of branches, inflorescences carried on terminal branches or stems, and reduced leaf complexity in developing inflorescences.
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.
Euphorbia misera is a semi-succulent shrub in the genus Euphorbia commonly known as the cliff spurge or coast spurge. A drought-deciduous shrub, it is typically found as a gnarled, straggly plant occupying seashore bluffs, hills and deserts. Like other members of its genus, it has a milky sap, which can be found exuding out of the light gray bark when damaged. The alternately-arranged leaves are round and folded in the middle, with small hairs on them. The "flowers" can be found blooming year-round, and are colored maroon or yellow in the center with 5 white to light-yellow petal-like appendages attached outside. This species is native to the Baja California peninsula and Sonora in Mexico, and the coast of southern California in the United States, where it is a rare species. It is threatened in some localities by the development of its coastal habitat, which tends to be prime locations for high-end residential and commercial developments.
Pilea cadierei is a species of flowering plant in the nettle family Urticaceae. The species is endemic to the southern Chinese provinces of Guizhou and Yunnan, as well as Vietnam. The specific epithet cadierei refers to the 20th-century botanist R.P. Cadière. P. cadierei has earned the Royal Horticultural Society's Award of Garden Merit for its hardiness and reliability as a houseplant. In warmer countries, usually within USDA zones 8-12, the plant may be grown outside year-round as a perennial, either in-ground or contained, and pruned about 50% during the autumn.

Vanilla pilifera is a species of vanilla orchid. It is native to Southeast Asia.
Dorstenia is a genus within the mulberry family, Moraceae. Depending on the author, there are said to be 100 to 170 species within this genus, second only in number to the genus Ficus within Moraceae. Plants of the World Online currently accepts 122 species. Dorstenia species are mainly known for their unusual inflorescences and growth habits. Dorstenia is named in honor of the German physician and botanist Theodor Dorsten (1492–1552). The type species is Dorstenia contrajerva.
Dorstenia contrajerva is a plant species in the family Moraceae. It is native to Northern South America and Central America, and is cultivated elsewhere. The species name "contrajerva" is the Latinized form of the plant's Spanish name, "contrahierba", a name for plants used for treating poisoning and venomous bites and stings, and for which its rootstocks are used in folk medicine. It is the type species of the Dorstenia genus and was first described by Carl Linnaeus in 1753.
Cleomella oxystyloides is a species of flowering plants in the cleome family, Cleomaceae, which is known by the common name spiny caper. It is native to the Mojave Desert straddling the border between California and Nevada. It grows in rocky and sandy desert habitat, often on alkaline soils. This is an annual herb producing an erect, branching stem which may reach 1.5 meters in height. The leaf is made up of three thick, firm leaflets 2 to 6 centimeters long, borne on a stout, straight petiole. The inflorescence is a dense head of flowers clustered about the stem at the leaf axils, each flower with four small yellow petals. The fruit is a small white or purple nutlet bearing the spine-like remnant of the flower receptacle.
Halerpestes cymbalaria is a species of buttercup known by the common names alkali buttercup and seaside buttercup. It is native to much of Eurasia and parts of North and South America, where it grows in many types of habitat, especially in moist to wet areas such as marshes, bogs, and moist spring meadows. It is a perennial herb producing several stems a few centimeters to nearly 40 centimeters long. Some are prostrate against the ground and are stolons which root in moist substrate, and some are erect. The leaves are variable in shape, the basal ones with notched or slightly divided leaf blades borne on long petioles, and any upper leaves much reduced in size. The inflorescence bears one or more flowers on erect stalks. The flower has five to eight pale yellow petals, each under a centimeter long. The protruding receptacle at the center of the flower becomes a cylindrical cluster of fruits, each of which is an achene.

Dudleya crassifolia is a species of drought deciduous, corm-forming succulent plant known by common name as the thick-leaf dudleya. It is an incredibly rare and cryptic plant native to one small locale less than a hectare in area on the Colonet peninsula in Baja California. It is threatened by urban development, including a proposed seaport. It is characterized by white, spreading flowers with leaf bases that are persistent on the stem. Although it did not receive as much media attention as the neighboring Dudleya hendrixii, it has been noted that the plant has several similarities to cryptic succulents like Anacampseros.
Jatropha moranii is a very rare subshrub in the genus Jatropha known commonly as Moran's lomboy. This species in the family Euphorbiaceae is endemic to a small area of Cabo San Lucas in Baja California Sur.
