Browntop millet is a quickly maturing grass frequently used for erosion control. It is cultivated as a food crop and for animal fodder in parts of South Asia. It must be grown with care if grown for ingestion, as it can absorb unhealthy levels of nitrates if over-fertilized.

Hooked bristlegrass (Setaria verticillata) is an annual grass species native to Europe but naturalized around the world. It is often considered a noxious weed. The inflorescence is equipped with many tiny spikes and bristles, which helps the grass spread its seeds by getting stuck in animal fur and carried across distances.

Soft feather pappusgrass is a resilient grass commonly found in arid and semi-arid regions. It features a compact, tufted form with narrow leaves, adapting well to low moisture environments. The plant is distinguished by its nine awned spikelets, which give it a distinctive fluffy appearance. These spikelets help soft feather pappusgrass disperse its seeds effectively, utilizing the wind for spread. As a drought-tolerant species, soft feather pappusgrass plays an important role in maintaining soil stability in harsh landscapes.

The white mangrove tree can be found around the world in tropical and subtropical regions. It grows in the coastal areas of tidal creeks, bays, and lagoons. The roots provide nursery shelters for many breeds of fish, and coastal birds roost in the branches. Laguncularia racemosa trees also provide important buffers against storm impacts along the coastline.

Watermelon (Citrullus lanatus) is a flowering plant with a vine-like appearance native to Western Africa. Watermelon bears fruit that are widely cultivated and consumed across the world.

A warm-season grass, the sixweeks three-awn is an important forage plant for animals in many dry areas of the world. It's considered a pioneer species that happens to be the first plant to colonize disturbed or bare ground, making it potentially invasive. This grass is used for weaving and thatching in India, while in Africa it's often used as a stuffing for camel saddles.

Citrullus colocynthis is a Mediterranean and African desert vine related to the watermelon. The fruit and the seed have been used for centuries as a food source in Europe and Africa, but contemporary researches have shown that colocynth contains adverse and toxic compounds and therefore the consumption of colocynth could be harmful to humans.

Cucumis dipsaceus, also known as Arabian cucumber or hedgehog cucumber, is an annual climbing herb that can be found in tropical and arid locations. The plant is native to eastern Africa, first found in Sudan, southern Egypt, and Ethiopia. The developed fruits of the plant change from green to yellow and contain many seeds. The hairs that cover the oblong fruits nickname this species the “hedgehog cucumber”. Cucumis dipsaceus has several usages, as fodder, medicine, and human consumption. The cucumber is normally collected in the wild, but has also been domesticated. The young shoots and leaves of the plant are traditionally cooked with groundnut paste, and with coconut milk when available. The fruit of the plant is used medicinally as an analgesic. C. dipsaceus has become invasive all across the Americas. This includes islands in Hawaii, several states in the U.S. and islands in South America as well. There are no known methods of control.

The nightshade's toxic fruit is a significant threat to grazing animals and livestock in the plant's native Africa, where it is widespread and highly invasive. It is also effective as a pesticide, particularly against cattle ticks.
