Warea amplexifolia is also known as 'clasping warea' or 'wide-leaf warea'. Clasping warea is an erect annual herb in the mustard family. These plants grow from 30 to 100 cm tall. The stalk may be unbranched, or often branching midway up the stem. The leaves of a young plant are slightly folded along the midrib, tipped upward, and the lobes at the base of the leaves reach around the stem. This characteristic led to the common name of clasping warea, and it can be used in field identification even when the plants are not in flower (USFWS 1999). The flowers of this summer annual herb are showy and are borne in small, rounded, puff-like clusters at the ends of the branches. Each flower has four pale purple petals with a rounded upper portion and an elongated stalk-like lower portion (USFWS 1991). The fruit is very distinctive, and helps to readily identify the plant. As the stalks turn brown and the leaves whither, the seeds are found in clusters of narrow down-curving seed pods, from 5 to 7 cm long. The pods split longitudinally, with small black seeds (USFWS 1999).
Distribution & Occurrence
Clasping warea is endemic to high pine (or sandhill) habitat, and is limited to dry, open woodlands. In this habitat, there is a relatively high diversity of herbaceous ground cover, especially wiregrass (USFWS 1999). This habitat is found on the Lake Wales Ridge, an elongated area of raised and usually dry soils, with elevations up to about 300 feet. The ridge extends from Central Highlands County northward, gradually disappearing in southern Marion County (USFWS 1999).
|There have been more than 20 sites discovered, but several have recently been destroyed and most are threatened by development and lack of fire (FNAI 2000).|
Conservation, Ecology & Research
There are four species of ants that occur around W. amplexifolia at Lake Griffin State Recreation Area, and it is believed that these ants help disperse warea seeds (USFWS 1999).
Exclusion of Fire.
Protect privately owned sandhills by purchase or conservation easement.
Manage sites with fire and monitor its effects on clasping warea.
Eradicate exotic pest species.
Establish new populations in conservation areas.
