Discussion
Holozonia filipes is the only perennial, continental tarweed with white corollas or filiform peduncles and is unique among the perennials for occurring in low-elevation, summer-hot, interior habitats. Like most of the perennial, continental tarweeds, H. filipes is self-incompatible and has a geographic distribution marked by major disjunctions between some populations.
