leaves are opposite, the shape and size of juvenile leaves often bearing little resemblance to the adult leaves. The
latex may be clear and colourless, pale yellow or milky white. The flowers are green, white, cream, yellow, orange, red, pink or brown, sometimes with contrasting markings. These are followed by elongated pod-like capsules, the two follicles eventually separating to reveal numerous seeds with long, silky hairs. ==Taxonomy==
