Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. – Daniel
David Tarrant continues to send photographs of Mexican plants that are poorly documented online, so here’s another. Thank you again, David.
The common name in Mexico for this species is pega ropa or “sticks to clothing”. Blazingstar is the name often associated with the genus Mentzelia, so another common name would be hispid blazingstar (hispida: covered in short, bristly hairs).
This late-summer flowering perennial or subshrub is native to much of Mexico as well as Guatemala. Line-drawings of the flower and fruit can be seen on page 21 of Flora Del Bajío Y De Regiones Adyacentes: Loasaceae (PDF). The National Commission for the Knowledge and Use of Biodiversity in Mexico also has more photographs online: Mentzelia hispida.
A different blazingstar was previously featured on BPotD: Mentzelia lindleyi.
