Taraxacum officinale (dandelion) is a widespread and
abundant rosette weed. It is almost ubiquitous in lawns and
occurs widely in pasture, grassy road verges etc. The leaves
are all in a basal rosette, and are soft, thin, quite light
green and without conspicuous hairs. They are elongate,
typically 10-20cm long and a few cm wide, with widely
spaced, coarse, acute teeth. The flower heads are on the
ends of sparsely hairy, elongate, hollow stalks. The flowers
are yellow and all strap-like. The fruit are in spherical
heads, with each fruit with a long (often about 1cm long)
narrow section between the body of the fruit and the
conspicuous pappus. The leaves and flower stalks exude a
milky sap when damaged.
