Hedeoma todsenii
Also called Todsen's Pennyroyal
Hedeoma todsenii is a rare species of flowering plant in the family Lamiaceae known by the common name Todsen's pennyroyal, or Todsen's false pennyroyal. It is endemic to New Mexico in the United States, where it occurs in the San Andres and Sacramento Mountains. It is federally listed as an endangered species of the United States.
This plant was discovered on the White Sands Missile Range in 1978 by Thomas K. Todsen (1918-2010) and described to science and named for him the following year. It is a rhizomatous perennial herb growing up to 20 centimeters tall with fragrant lance-shaped leaves. The tubular flowers are red-orange or occasionally yellow in color and bloom in the summer rainy season. Flowers occur rarely, with only 20% of the plants flowering in a given season. The plant reproduces vegetatively, forming wide mats of many clones all arising from the rhizome of one plant.
