Pseudolithos caput-viperae

Pseudolithos caput-viperae is a species of succulent plant in the genus Pseudolithos.^[1] It is a small, leafless plant up to 15–40 millimetres (0.59–1.57 in) tall and either green or brownish. First discovered and described in the 1970s by botanists John Jacob Lavranos and Renato Bavazzano,^[2] it is native to Somalia. The seedlings of the plant are identical to Pseudolithos migiurtinus, but start to branch after a year, making this the only member of Pseudolithos that is not just a single squat stem.^[3] Its Latin species name means "snake head".^[4]
