Note: V. neomexicana is not supposed to exist in the Big Bend area according to the BONAP map; however it appears in the SEINet Big Bend Checklist. It is possible that the images below are actually V. perennis or V. canescens; however, there are differences in leaf shape, hairiness, and bracts with the images being more like V. neomexicana in these respects.
