in botany: A genus of plants belonging to the class of pentandra, and to the order of pentagynia; and in the natural system arranged under the 35th order, Senticeae. The calyx is divided into ten segments. The petals are five, and are inserted into the calyx. The styles are attached to the side of the germs. The seeds are five. There are three species belonging to this genus, the procumbens, erecta, and alticola. The procumbens, or reclining sibbaldia, is a native of North Britain, having never been discovered in the southern parts of the island. It grows on Ben-Lomond and Ben-Mor, within a mile of the summit. It is distinguished by a procumbent or trailing stem; by three leaves growing on the top of a small footstalk, which are thin at the extremity, and somewhat hairy. The flowers are yellow, and blossom in July or August.
