(Tribulus cistoides)



Tribulus cistoides, also called wanglo (in Aruba), the Jamaican feverplant or puncture vine, is a species of flowering plant in the family Zygophyllaceae, which is widely distributed in tropical and subtropical regions. 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). Some species are cultivated as ornamental plants in warm regions. Some, notably T. cistoides, T. longipetalus, T. terrestris, and T. zeyheri, are considered weeds. Tribulus omanense is the national flower of Dubai. Thirteen species of Tribulus are accepted by The Plant List, but there are many names still unresolved and needing further study.
