A single female poinsettia flower with stigma, style, and enlarged ovary can be seen emerging from its involucre (cluster of bracts fused together) on a thick pedicel (stalk) that's almost as long as the flower itself. Also emerging from the involucre are a number of withered male flowers (stamen and anthers both visible) that still have yellow pollen on them.

A single female poinsettia flower with stigma, style, and enlarged ovary can be seen emerging from its involucre (cluster of bracts fused together) on a thick pedicel (stalk) that's almost as long as the flower itself. Also emerging from the involucre are a number of withered male flowers (stamen and anthers both visible) that still have yellow pollen on them. The involucre has a nectar gland emerging from it (that look like two yellow lips). The involucre also has small saucer shaped structures emerging from it; I'm not sure what they are (they're more easily visible in my other poinsettia pictures). The entire inflorescence (involcure, male flowers, and female flower) is called a cyanthium. The cyanthium is growing up from a stem's branching point, where a bract is emerging. The red leaves surrounding the inflorescences (mostly out of focus) are bracts. The scale bar (at the bottom) is 5mm long.
