Euphorbia erythrina is a small perennial plant with narrow, alternate leaves that are often lanceolate, but quite variable. It exudes milky latex from stems, leaves and flowers, which is typical of many Euphorbia species. The flowers are leafy green terminal umbels intricately branched.
The published information on this plant is confusing in aspects such as the geographic distribution (Eastern Cape coastal or all along the southern coast from the Western Cape), flowering time (June to October or February to August). There may be some study and identification issues to be resolved; Bean and Johns mention three similar species that may be mixed up with this one to some extent (2005). Maybe this fascinating genus holds much more to surprise us beyond that what we have learnt thus far.
