Euphorbia hispida is included in this Flora on the basis of a single collection, Ducloux 4686, in Paris (P). The distinctive indumentum superficially resembles that of E. hirta but the hairs are uniformly long, not a mixture of long and very short.
One of us (Ma) does not agree with the treatment of this species here.
