A single female poinsettia flower with stigma, style, and ovary can be seen emerging from its involucre (cluster of bracts fused together) on the right half of this image; the involucre also has a nectar gland emerging from it (that look like two yellow-green lips).  The entire inflorescence (involcure and female flower) is called a cyanthium.  On the left of the image a number of withered male flowers and their nectar glands can be seen emerging from shriveled involucres.  The red leaves surrounding the inflorescences (mostly out of focus) are bracts.
