Botany picture #72: Euphorbia amygdaloides
Euphorbia amygdaloides (Euphorbiaceae), Germany, 2005. Euphorbia is one of the largest plant genera and usually easily recognized by the highly modified inflorescences. The flowers are arranged in a structure called a cyathium which consists of a central female flower reduced only to its reproductive organ, several male flowers reduced only to its reproductive organ, and a ring of glands (in this case they are the half-moon shaped, yellowish structures). Cyathia are then arranged in cymes. This particular species is a typical part of the spring flower carpets in Germany.
