Phedimus is a genus of plants from the family of thick-leaf plants (Crassulaceae). In German it is also referred to as Asian fat hen .
description
The species of the genus Phedimus are perennial or rarely annual , herbaceous , usually bare succulent plants. Their shoots occasionally lignify at the base. Sometimes they have a woody rhizome . Their flat, mostly serrated or toothed leaves are arranged alternately or opposite. Several hydathodes are located on the underside of the leaves along the leaf margins .
The flower stems are erect or ascending. Their inflorescence usually forms dense, multi-flowered cymes or ebony . The five- to six-fold (rarely four to seven-fold) obdiplostemonen flowers are sessile, almost sessile or short-stalked and each have a bract . Their green, mostly unequal, broadly seated sepals are elongated to linear. The white, pink, red to slightly purple or yellow petals are free and mostly spread out at the base.
The fruit is a mostly spread out and rarely upright follicle fruit . The brown seeds it contains are egg-shaped and 1 to 1.4 millimeters in size.
Systematics and distribution
The genus Phedimus is common in Europe and Asia. The first description was made in 1817 by Constantine Samuel Rafinesque . The botanical name of the genus Phedimus is derived either from the Greek word "φαίδιμος" (phaidimos) for shiny or refers to Phedimus, the archbishop of Amasea and Metropolitan of Pontia.
