The difference between Euphorbia pilosa and Euphorbia pulcherrima

1. Difference of blades

The leaves of Euphorbia milii are alternate, usually concentrated on young branches, in shape of obovate or oblong-spoon-shaped, about 1.5-5 cm long and 0.8-1.8 cm wide. The stipules are subulate, very thin, and fall off early.

The leaves of the Diamond Tree are fewer and fleshy, usually growing in five rows on the top ridge of young branches. They are obovate or obovate-oblong to spoon-shaped, wider than the former, about 4.5-12 cm long and 1.3-3.8 cm wide. The stipules are thorn-like and persistent.

2. The difference between flowers

Euphorbia milii has a dichotomous compound inflorescence with two bracts, which are kidney-shaped, bright red on the upper side and light red on the lower side. The involucre is bell-shaped with 5 lobes on the edge and the lobes are lyre-shaped.

The inflorescence of King Kong is dichotomous, with two bracts that fall off early. The involucre is broadly bell-shaped, with 5 lobes on the edge. The lobes are semicircular, with ciliated edges, fleshy glands, thick edges, and entire margins.
