Comment:

Desmodium spp., commonly known as Beggars lice is a woody trailing legume in the Fabaceae family.  There are dozens of species and there is indecision in the taxonomic world in defining the genus.  This plant can be used as a living mulch or green manure as they are able to improve soil fertility via nitrogen fixation.   They can also be used as livestock fodder.   The hairy seedpods readily cling to fur and clothing so both animals and humans unwittingly spread their seeds.  They germinate readily and can become weedy.

This herb produces a triangular seed that sticks like a tick.
