+ | | description=The dandelion is an herbaceous plant, with a perennial fusiform root. The leaves, which spring immediately from the short upright rhizome, are long, pinnatifid, generally runcinate, with the divisions toothed, smooth, and of a fine 'green color. [...] | ||
+ | |||
+ | The flower-stem rises from the midst of the leaves, six inches or more in height. It is erect, simple, naked, smooth, hollow, fragile, and terminated by a large golden-colored flower, which closes in the evening and expands with the returning light of the sun. The involucre is smooth and double, with the outer scales bent downward. The florets are very numerous, ligulate, and toothed at their extremities. The receptacle is flat and naked. The pappus is stipulate, and at the period of maturity is disposed in a spherical form, and is so light and feathery as to be easily borne away by the wind, with the achene attached. | ||

The rhizome portions show a small pith. The powder is light brown; when examined under the microscope it exhibits parenchyma cells which are large, thin-walled and contain irregular masses of inulin; fragments with yellowish-brown lacticiferous vessels; trachea; reticulate; intermediate fibers non-lignified, with irregular, simple and oblique pores.}} | ||
