Plants in the Desmodium genus are mostly inconspicuous plants; few have bright or large flowers. Though some can become sizeable plants, most are herbs or small shrubs. Their fruit are loments, meaning each seed is dispersed individually enclosed in its segment. This makes them tenacious plants and some species are considered weeds in places.

Desmodium paniculatum
Panicled tickrefoil (scientific name Desmodium paniculatum) is the most commonly documented tick trefoil in Dallas County. It grows along the edge of woodland areas, in partially shaded riparian habitats, and may be associated with prairie remnants. It can rebound in areas that have been disturbed and can aide in erosion control.
Desmodium tweedyi
Tweedy's Tick Clover (scientific name: Desmodiium tweedyi) is endemic to the North Texas area and is only documented in limestone prairie remnants. It can be found in woodland edges, partially shaded areas, and can tolerate xeric soil conditions. Unlike Desmodium paniculatum, it prefers drier soil and will not rebound easily in areas with disturbed soils. It is at risk of extinction due to its small endemic range.
