When the portion of stem to which the flowers are attached is short and the stalks of all of the flowers are so elongated as to bring all of the flowers to about the same level then a corymb results. A further modification in which the portion of stem to which the flowers are attached is so short that the flower stalks appear to be of the same length and attached in a circle around the stem results in the umbel, the form of cluster characteristic of the Parsley Family, called UmbelUf- ercE, on account of the character of the flower cluster. Of this family the Parsnips, Carrots, and others are common. The um- bel is also common among the Milkweeds. Umbels may be simple or compound, that is, so branched as to be composed of a number of small umbels. {Fig. 32.).
