Euphorbia polygona var. major
Synonyms: Euphorbia horrida var. major, Euphorbia horrida var. nova, Euphorbia polygona var. major
Common Name: African milk barrel
Origin: Euphorbia polygona originates from the Eastern Cape of Southern Africa, dominant in rocky quartzite fields.
Description: Although now considered the same species, E. polygona and E. horrida possess slight morphological differences. E. polygona is a glaucous, cylindrical, basally clumping spurge that develops a cactus-like form of upright columns. The stem is covered in numerous peduncles, from which few to many spines emerge.
E. horrida possesses irregularly clumping stems, and a less dense form, with hairy peduncles and white striped flesh. Additionally, the ribs and spines of the major variety are distinctively wavy.
In summer, E. polygona will produce dark purple cyathia, while the inflorescence of E. horrida will be greenish-yellow.
