The grain of grain sorghum is utilized for human consumption, animal feed, and ethanol manufacturing. It is commonly grown in tropical and subtropical countries, originating in Africa. The grain is used to make liquor, animal feed, and bio-based ethanol, among other things.

An important subsistence crop, pearl millet is hardy and drought-tolerant. Also known as Cenchrus americanus, it grows well near deserts where the rainfall is low. It has been cultivated in the United States since the 1850s and there are records of this important crop being grown since 2000 B.C.

Combretum glutinosum is a deciduous shrub native to African savannahs, recognized for its robust, twisted branches and dense foliage. Its leathery leaves adapt well to arid conditions, and the conspicuous yellowish-green flowers exhibit a unique puffball arrangement, attracting various pollinators. During the dry season, combretum glutinosum's thick bark aids in water retention, underscoring its resilience in harsh environments.

Strychnos spinosa, the Natal orange, is a tree indigenous to tropical and subtropical Africa. It produces, sweet-sour, yellow fruits, containing numerous hard brown seeds. Greenish-white flowers grow in dense heads at the ends of branches (Sep-Feb/Spring - summer). The fruits tend to appear only after good rains. It is related to the deadly Strychnos nux-vomica, which contains strychnine. The smooth, hard fruit are large and green, ripen to yellow colour. Inside the fruit are tightly packed seeds, which may be toxic, surrounded by a fleshy, brown, edible covering. Animals such as baboon, monkeys, bushpig, nyala and eland eat the fruit. The leaves are a popular food source for browsers such as duiker, kudu, impala, steenbok, nyala and elephant.

Native to the African savanna, monkey guava (Diospyros mespiliformis) is an important food source for African animals. Grazing animals typically eat its leaves, while jackals, in particular, are fond of its fruit, leading to another nickname: jackalberry. It frequently grows over termite mounds because the termites aerate the soil around it, while it offers them protection from the sun.

This tropical tree, the tallow wood, produces leaves that smell like almonds. Although this tree is sometimes cultivated for its yellow fruits, it is often found growing wild in southern parts of the United States. The leaves and seeds contain cyanide.

Wandering Jew has been introduced to North America where it is considered a noxious weed. It can be highly invasive - spreading across crops and pastures, outcompeting more desirable plants.

Sago pondweed (Stuckenia pectinata) is an aquatic plant commonly found growing in fresh or brackish water. Unlike other aquatic plants, the sago pondweed does not float above the water. It is completely submerged. Insects, water birds and other aquatic animals feed on its tuberous roots and help to distribute the plant to other areas. Also called fennel pondweed and ribbon weed.

Pond lovegrass has historically been used as animal fodder or a forage crop, even a cereal crop during times of famine. This erect annual grass can be naturally found in disturbed areas such as roadsides. It flowers through late summer and autumn and prefers sun. The grass has been utilized in flower beds, although it has invasive weed potential.

Native to Europe, Asia, and Africa, the royal fern is a common fern growing along the streams and pools under the forest. There is fertile frond divergence in royal fern which makes it a "flowering" appearance. It is widely cultivated as an ornamental plant.

The milky white flowers of the red spikethorn (Gymnosporia senegalensis) grow at intervals along its red branches. Despite its unpleasant spines, it is an important food source for African animals, with monkeys, rhinos, birds and even larval butterflies depending on its fruit, bark and leaves.

Eragrostis atrovirens is a species of grass. It is found in the tropical and subtropical parts of the world.

Curculigo pilosa is a perennial herbaceous plant that thrives in the shaded understories of tropical forests. Its noticeable features include a dense rosette of long, lance-shaped leaves and a central spike of small, yellow flowers. The pilose, or hairy, surface of both stems and leaves helps in retaining moisture, a crucial adaptation for its humid habitat.

With its self-supporting growth form, the Setaria helvola has simple, broad leaves with white flowers. It's widely known as a common weed that grows in lawns, sidewalks, and other places. It can grow from 20 cm to well over a meter. All of its leaf blades are hairless on the upper surfaces and can measure up to 30 cm long.

The micheli's galingale is an annual herbaceous plant and reaches stature heights of 2 to 10 cm , rarely up to 15 cm . The micheli's galingale grows in small, mostly dense lawns. The ascending stem is triangular. The leaves are divided into leaf sheath and leaf blade. The lower leaf sheaths are dark red.

Ludwigia leptocarpa is also known as anglestem primrose-willow, and is native to the United States, mostly the state of Florida. It blooms yellow flowers all year long and is found growing in wetlands.

Milk and wine crinum is a striking perennial bulb known for its lush, strap-like leaves and eye-catching, funnel-shaped flowers that bloom in clusters. The large, fragrant blooms are typically white or pink, rising on tall stalks and often used in ornamental gardening. Thriving in warm, humid environments, milk and wine crinum benefits from well-draining soil and can tolerate brief flooding, adapting well to waterside landscapes.

Andropogon pseudapricus is a resilient grass native to dry, open landscapes, adapting to harsh conditions with its deep roots and tall, slender stems. Its clumping growth pattern and fluffy seed heads, which appear in the warmer months, aid in dispersal by wind. Gracefully swaying, the plant provides shelter to fauna and stabilizes soil.

Maize (Zea mays) is a well known domesticated cereal grain first domesticated in Mexico. In much of the world it is also called corn. Worldwide cultivation of maize surpasses other prominent grains like wheat and rice. Maize must be planted in the spring due to its intolerance for cold weather.

Drosera indica is an unbranched, annual herbaceous plant, supported by a fibrous root system and reaching a height of 5–50 cm (2–20 in). Leaves are narrowly linear, up to 10 cm [4 in] long with 1–1.5 cm [0.4–0.6 in] pedicels. Young plants stand upright, while older ones form scrambling stems with only the newest growth exhibiting an upright habit. The plant can be yellow-green to maroon in color. Flower petals can be white, pink, orange, or purple. Its chromosome count is 2n=28.
