Haploesthes robusta

Haploesthes robusta is a Mexican species of flowering plants in the daisy family. It has been found only in the state of Coahuila in northern Mexico.
The genus name is sometimes spelled "Haploësthes," with two dots over the first "e" to indicate that the "o" and the "e" are to be pronounced in separate syllables. This is optional; either spelling is equally acceptable.
"Haploesthes robusta" grows along stream banks in areas with gypsum soil. It is a sprawling, succulent shrub with stems up to long. Leaves are triangular in cross-section.
