Symmetry in biology Most radially symmetric animals are symmetrical about an axis extending from the center of the oral surface, which contains the mouth to the center of the opposite, , end. Radial symmetry is especially suitable for sessile animals such as the sea anemone, floating animals such as jellyfish, and slow moving organisms such as starfish. Animals in the phyla Cnidaria and Echinodermata are radially symmetric, although many sea anemones and some corals have bilateral symmetry defined by a single structure, the siphonoglyph. Many flowers are radially symmetric or actinomorphic. Roughly identical flower parts – petals, sepals, and stamens – occur at
Phyla nodiflora look, which is why the plant is sometimes called matchweed. It is similar to the related species Phyla lanceolata, but differs in having much shorter leaves that are often blunt and much more rounded. Both species are common as weeds and in the ornamental environment. Common names in India include bukkan (Hindi), ratolia, vakkan (Marathi), podutalai (Tamil), vasir, and vasuka (Sanskrit). It is used medicinally to treat suppuration, common colds, and lithiasis. "Lippia canescens" Kunth, "Lippia incasiomalo" (Small) Tildsoan, "Lippia lickiflora" (L.) Michx., "Lippia nodiflora" var.
