The Acer circinatum
The Acer circinatum is known for its colour and unique shape. Both monocotyledon and dicotyledonous flowers use the flowers as a sexual organ. A flower consist in the 4 following parts: Calyx – the outer whorl of sepals; typically these are green, but are petal-like in some species corolla – the whorl of petals, which are usually thin, soft and colour to attract insects that help the process of pollination. Androecium (from Greek andros oikia: man's house) – one or two whorls of stamens, each a filament topped by an anther where pollen is produced. Pollen contains the male gametes. Gynoecium (from Greek gynaikos oikia: woman's house) – one or more pistils. The female reproductive organ is the carpel: this contains an ovary with ovules (which contain female gametes). A pistil may consist of a number of carpals merged together, in which case there is only one pistil to each flower, or of a single individual carpel (the flower is then called apocarpous). The sticky tip of the pistil, the stigma, is the receptor of pollen. The supportive stalk, the style becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma, to the ovules, carrying the reproductive material.
