Wedge Sandmat Chamaesyce deltoidea

Euphorbia deltoidea, also called wedge sandmat, is a species of flowering plant endemic to Florida in the United States. The taxonomy of the plant is difficult, with some authorities dividing it into four subspecies and some into three; also, it is frequently listed as a member of the old genus Chamaesyce. One subspecies, ssp. deltoidea, is a federally listed endangered species called deltoid spurge. It is found only in Miami-Dade County. Another subspecies, ssp. adhaerens, is often included with it under the name deltoidea instead of separately, making it difficult to keep count of how many endangered plants there are. This is generally dealt with by placing the "endangered species" label on any taxon within the species that is limited to Miami-Dade County, however many names they may have. Wikipedia →
