Desmodium is a genus of plants in the legume family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time. Species are distributed widely – from Quebec to northern Argentina in the Americas, across northern and southern tropical Africa, in the southern Arabian Peninsula, in Myanmar and Thailand, New Guinea, and northern and eastern Australia.
Passiflora lutea, commonly known as yellow passionflower, is a flowering perennial vine in the family Passifloraceae, native to the central and eastern United States. The vine has three-lobed leaves and small, yellowish-green, fringed flowers that appear in the summer, followed by green fruit that turn almost black at maturity. It grows in moist to wet habitats.
Hackelia virginiana, a biennial plant, is commonly known as beggar's lice, sticktight or stickseed. However, the common names beggar's lice and stick-tight are also used for very different plants, such as Desmodium species that are also known as "tick-trefoil".
Hieracium umbellatum, the Canadian hawkweed, Canada hawkweed, narrowleaf hawkweed, or northern hawkweed, is a flowering plant in the family Asteraceae.
Desmodium incanum, also known as creeping beggarweed, Spanish clover, Spanish tick-trefoil or hitchhikers is a perennial plant native to Central and South America. In Hawaiʻi it is known as kaʻimi or kaimi clover from the Hawaiian for "seeker". Initially introduced as forage crop around the world, it has spread to many places although it is no longer an important fodder crop. It is considered a weed both within and outside its native range. It has spread through Florida and across the southern USA into southern Texas and across many Pacific islands, including Hawaii.
Asarum canadense, commonly known as Canada wild ginger, Canadian snakeroot, and broad-leaved asarabacca, is a herbaceous, perennial plant which forms dense colonies in the understory of deciduous forests throughout its native range in eastern North America, from the Great Plains east to the Atlantic Coast, and from southeastern Canada south to around the Fall Line in the southeastern United States.
Asclepias speciosa is a milky-sapped perennial plant in the dogbane family (Apocynaceae), known commonly as the showy milkweed and is found in the western half of North America.
Grona triflora, known as creeping tick trefoil or three-flower beggarweed, is a plant in the family Fabaceae. It is native to tropical regions around the globe and introduced to subtropical regions including the southern United States.
Viburnum lantanoides is a perennial shrub of the family Adoxaceae, growing 2–4 meters (6–12 ft) high with pendulous branches that take root where they touch the ground. These rooted branches form obstacles which easily trip walkers – hence the common name.
Thorybes bathyllus, the southern cloudywing, is a North American butterfly in the family Hesperiidae. Southern cloudywings can be difficult to identify because of individual variation and confusing seasonal forms. In the south, where it has two broods per year, two seasonal forms occur. Spring forms are usually lightly marked and resemble confused cloudywings. Summer forms tend to be more boldly marked, by comparison, making identification easier. However, summer confused cloudywings are also strongly patterned, which makes identifying them more difficult. Their rapid flight is very erratic, though it is closer to the ground than in some of its close relatives.
Desmodium paniculatum, the panicled-leaf ticktrefoil, narrow-leaf tick-trefoil or panicled tickclover, is a perennial herb in the pea family, Fabaceae. Belonging to a nearly cosmopolitan genus, the panicled-leaf ticktrefoil is a common native to Eastern North America, ranging from Quebec to Florida and as far West as Texas, Nebraska, and Ontario. The sticky loment can be found in disturbed areas that receive plenty of light, such as roadsides, parks, and abandoned fields.
Liatris punctata is a species of flowering plant in the family Asteraceae known by the common names dotted gayfeather, dotted blazingstar, and narrow-leaved blazingstar. It is native to North America, where it occurs throughout the plains of central Canada, the central United States, and northern Mexico.
Desmodium × humifusum is a species of flowering plant in the legume family known by the common names trailing tick-trefoil, eastern trailing tick-trefoil, and spreading tick-trefoil. It is native to the eastern United States, where it has been reduced to scattered populations in the states of Massachusetts, Connecticut, and Indiana. It once had a wider distribution but it has likely been extirpated from Delaware, Maryland, New Jersey, New York, Rhode Island, Virginia, West Virginia, and Missouri.
Desmodium illinoense, the Illinois ticktrefoil, is a flowering plant in the bean family (Fabaceae), native to the central United States and Ontario, Canada. Illinois ticktrefoil grows in sunny places, such as prairies and oak savannas of the Great Plains and Great Lakes regions.
Desmodium glabellum is a species of flowering plant in the legume family Fabaceae. It is native to the eastern and central United States. It is commonly called Dillenius' tick-trefoil in honor of Johann Dillenius, a British botanist of German birth. It is also known as the tall tick-trefoil.
Hylodesmum glutinosum is a species of flowering plant in the family Fabaceae. Common names include large tick-trefoil, clustered-leaved tick-trefoil, large-flowered tick-clover, pointed tick-trefoil, beggar's lice and pointed-leaved tick-trefoil. It occurs in eastern Canada, the central and eastern United States, and northeastern Mexico.
Desmodium tortuosum, the twisted tick trefoil, dixie tick trefoil, tall tick clover, Florida beggarweed, and giant beggar weed, is a species of flowering plant in the family Fabaceae. It is native to Latin America, and widely introduced as a forage to much of the rest of the world's subtropics and tropics.
