Menodora is a genus of perennial plants and shrubs in the olive family Oleaceae. Its 23 species (as per Green 2003) are found in the temperate Americas and in southern Africa. These are uniform species of deserts and arid grasslands or savannas.
The usually bisexual flowers have a united calyx with 5-10 lobes (rarely more), while the corolla is similarly united but with 4-6 lobes. The corolla is a pretty, bright yellow (except for M. spinescens, whose corollas are white), and is often scented. The fruit is a didymous, bilobed capsule with each globose locule or lobe containing 2-4 seeds. In the majority of species, each locule also features circumscissile dehiscence. Vegetatively, the plants are generally unremarkable, with a "green-stick" look that is common to many desert plants. In the dry seasons, plants may lose their generally small or reduced leaves altogether. Leaf shape within the genus is highly variable, ranging from short and linear to almost feathery and pinnatisect. Leaves are most commonly found arranged in opposite pairs, but in some individuals may be predominantly alternate.
Willis Jepson mistakenly suggested that the origin of the genus name was rather obscure, perhaps deriving from the Greek for "half-moon spear" for the appearance of the dehisced fruit on its pedicel. In reality, the name was specifically derived from the Greek μενος (menos), meaning "force," and δωρον (doron), meaning "gift," referring to the sustenance the plants provided to the horses of Humboldt and Bonpland (1809) when they first encountered the genus in the present state of Hidalgo in Mexico.

Menodora longiflora has occasionally been treated as the monotypic genus Menodoropsis (Small, 1903) due to the extraordinary length of its corolla tube (to nearly 6 cm, as opposed to typical lengths of 0.3 to 0.7 cm in most other species), but based on both morphological and molecular data it plainly belongs within Menodora. Small took the name for the genus from one of the sections of the Menodora recognized by Asa Gray (1852). Neither the sectional classification of Gray (1852) nor Steyermark (1932) have been upheld by recent molecular studies.
One of the more distinctive things about this genus is the pattern of disjunction or non-continuous distribution. In the Americas, the distribution jumps over the tropics, with only a few species whose individual distributions just cross into the tropics (e.g., north to central Bolivia, and south to Oaxaca in Mexico). This is a common pattern found in many genera, but not many others with a similar amphitropical distribution also have connections across the Atlantic with Africa. This intercontinental distribution of Menodora was often cited as evidence of continental drift or the breakup of the Pangaea or Gondwanan supercontinents, but more recently it has been judged to be the result of long distance dispersal.
Asimina is a genus of small trees or shrubs described as a genus in 1763. Asimina is the only temperate genus in the tropical and subtropical flowering plant family Annonaceae. Asimina have large, simple leaves and large fruit. It is native to eastern North America and collectively referred to as pawpaw. The genus includes the widespread common pawpaw Asimina triloba, which bears the largest edible fruit indigenous to the United States. Pawpaws are native to 26 states of the U.S. and to Ontario in Canada. The common pawpaw is a patch-forming (clonal) understory tree found in well-drained, deep, fertile bottomland and hilly upland habitat. Pawpaws are in the same plant family (Annonaceae) as the custard apple, cherimoya, sweetsop, soursop, and ylang-ylang; the genus is the only member of that family not confined to the tropics.
Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.
Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct. The extant genera include Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
Stachys is a genus of plants, one of the largest in the mint family Lamiaceae. Estimates of the number of species vary from about 300, to about 450. Stachys is in the subfamily Lamioideae and its type species is Stachys sylvatica. The precise extent of the genus and its relationship to other genera in the subfamily are poorly known.
Lobelioideae is a subfamily of the plant family Campanulaceae. It contains 32 genera, totalling about 1200 species. Some of the larger genera are Lobelia, Siphocampylus, Centropogon, Burmeistera and Cyanea.
Lycium is a genus of flowering plants in the nightshade family, Solanaceae. The genus has a disjunct distribution around the globe, with species occurring on most continents in temperate and subtropical regions. South America has the most species, followed by North America and southern Africa. There are several scattered across Europe and Asia, and one is native to Australia. Common English names for plants of this genus include box-thorn and desert-thorn.
Parkinsonia, also Cercidium, is a genus of flowering plants in the pea family, Fabaceae. It contains about 12 species that are native to semi-desert regions of Africa and the Americas. The name of the genus honors English apothecary and botanist John Parkinson (1567–1650).
Sapindus is a genus of about five to twelve species of shrubs and small trees in the lychee family, Sapindaceae, native to warm temperate to tropical regions of the world. The genus includes both deciduous and evergreen species. Members of the genus are commonly known as soapberries or soapnuts because the fruit pulp is used to make soap. The generic name is derived from the Latin words sapo, meaning "soap", and indicus, meaning "of India".
Lamium galeobdolon, commonly known as yellow archangel, golden dead-nettle, artillery plant, aluminium plant, or yellow weasel-snout, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant. It displays the zygomorphic flower morphology, opposite leaves, and square stems typical of the mint family, Lamiaceae. The flowers are soft yellow and borne in axial clusters, with a prominent 'hood'. It spreads easily and so has been commonly used as an ornamental ground cover. It can be invasive in places where it is not native and caution must be taken when planting in these areas.
Chilopsis is a monotypic genus of flowering plants containing the single species Chilopsis linearis. It is known commonly as desert willow or desert-willow because of its willow-like leaves, but it is not a true willow – being instead a member of the catalpa family.
Phacelia crenulata is a species of flowering plant in the borage family, Boraginaceae. Its common names include notch-leaf scorpion-weed, notch-leaved phacelia, cleftleaf wildheliotrope, and heliotrope phacelia. Phacelia crenulata has an antitropical distribution, a type of disjunct distribution where a species exists at comparable latitudes on opposite sides of the equator, but not at the tropics. In North America, it is native to the southwestern United States as far east as Colorado and New Mexico, and Baja California and Sonora in Mexico. In South America, it is native to southern Peru, western Bolivia, and northern Chile.
Goodeniaceae is a family of flowering plants in the order Asterales. It contains about 404 species in twelve genera. The family is distributed mostly in Australia, except for the genus Scaevola, which is pantropical. Its species are found across most of Australia, being especially common in arid and semi-arid climates.
Osmanthus heterophyllus, variously known as holly osmanthus, holly olive, and false holly, is a species of flowering plant in the olive family Oleaceae, native to eastern Asia in central and southern Japan and Taiwan.
Nestegis is a genus of flowering plant in the olive family, Oleaceae. There are five currently accepted species in the genus: three species are endemic to New Zealand, while one can be found on New Zealand and Norfolk Island. Another is restricted to Hawaiʻi.
Uvaria is a genus of flowering plants in the family Annonaceae. The generic name uvaria is derived from the Latin uva meaning grape, likely because the edible fruit of some species in the genus resemble grapes.
Schaefferia is a genus of flowering shrubs and small trees in the family Celastraceae. The generic name honours German mycologist and clergyman Jacob Christian Schäffer (1718–1790). Members of the genus are found in the Neotropics. The plants are dioecious, with flowers that are unisexual by abortion. The flowers are usually clustered in the leaf axil, although they are solitary in some species. The calyx of the flowers has four lobes, and the corolla consists of four petals. The ovary consists of two locules; each locule has a single ovule which develops into a single seed. The fruit is a drupe.
Ammandra is a monotypic genus of flowering plant in the palm family found in Colombia and Ecuador, where it is endangered. The sole species is Ammandra decasperma, although another species name has been proposed. They are a pinnate-leaved, dioecious palm whose seeds and petioles are used in button and basket making, respectively. It is commonly called ivory palm or cabecita.
Grayia spinosa is a species of the genus Grayia in the subfamily Chenopodioideae of the flowering plant family Amaranthaceae, which is known by the common names hop sage and spiny hop sage. It is widely distributed across the Western United States, where it grows in a number of desert and mountain habitats.
Menodora scabra is broom-like shrub in the Olive Family (Oleaceae), known by the common name rough menodora or broom twinberry. It is a popular desert garden plant.
The Solanaceae, or the nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
