Title: Identification of stinging plant in Central Texas
Answered by: Nan Hampton
Your description sounds like one of the species of Tragia, most likely one of the following:
Tragia betonicifolia (Betonyleaf noseburn). Here is more information from the USDA Plants Database.
Tragia brevispica (Shortspike noseburn). Here are photos of T. brevispica.
Tragia ramosa (Branched noseburn). Here are more photos and information from Southwest Environmental Information Network.
They are small, unremarkable (except for their sting) plant that you not necessarily notice. Here is an explanation (Tragia ramosa) of how this stinging mechanism works.
By the way, take the name "noseburn" to heart. I have a friend who decided to test this name and it is, indeed, accurate!
