It has a wide distribution in tropical and subtropical regions of the Americas, sub-Saharan Africa, Asia, Australasia, and the Pacific.

Tribulus is a genus of plants in the family Zygophyllaceae and found in diverse climates and soils worldwide from latitudes 35°S to 47°N. The best-known member is T. terrestris (puncture vine), a widespread invasive species and weed. Tribulus species are perennial, but some grow as annuals in colder climates. The leaves are opposite and compound. The flowers are perfect (hermaphroditic) and insect-pollinated, with fivefold symmetry. The ovary is divided into locules that are in turn divided by "false septa" (the latter distinguish Tribulus from other members of its family). Tribulus omanense

Triumfetta is a genus of plants in the family Malvaceae. Burbark is a common name for plants in this genus. The genus was originally described and published by Carl Linnaeus in his book Sp. Pl. on page 444 in 1753. There are about 176 species which are widespread across tropical regions.

Cordia is a genus of flowering plants in the family Cordiaceae. It contains 228 species of shrubs and trees, that are found in tropical and subtropical regions worldwide. Many of the species are commonly called manjack, while bocote may refer to several Central American species in Spanish. The generic name honours German botanist and pharmacist Valerius Cordus (1515–1544). Like most other Boraginales, the majority have trichomes (hairs) on the leaves.

With over 100 species, it is found in the tropics and warm temperate regions. Portulacas are also known as the purslanes. Common purslane (Portulaca oleracea) is widely consumed as an edible plant, and in some areas it is invasive. Portulaca grandiflora is a well-known ornamental garden plant. Purslanes are relished by chickens. Some Portulaca species are used as food plants by the larvae of some Lepidoptera species

Fimbristylis is a genus of sedges. A plant in this genus may be known commonly as a fimbry or fimbristyle. There are over 300 species distributed worldwide. Several continents have native species but many species have been introduced to regions where they are not native. Some are considered weeds. These are typical sedges in appearance, with stiff, ridged stems and cone-shaped terminal panicles of spikelets. They are found in wet environments, and are most diverse in tropical and subtropical regions.

Digitaria is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. Digitus is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce.
