Problem:Context_1 : Jovibarba ("beard of Jupiter") is a small genus of three species of succulent flowering plants in the family Crassulaceae, endemic to mountainous regions in the southeastern quadrant of Europe. The genus is sometimes classified as a subgenus of "Sempervivum", to which it is closely related. "Jovibarba" have pale-greenish-yellow or yellow actinomorphic flowers with about six petals, while "Sempervivum" have generally pinkish flowers with around twice as many petals, which open more widely than jovibarba flowers. The common name hen and chicks is applied to some "Jovibarba" species (and also species in several other genera). Context_2 : Sempervivum (Brit. , U.S. sem-per-VEE-vum) is a genus of about 40 species of flowering plants in the Crassulaceae family, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation "Sempervivum", literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations. Context_3 : Malope is a genus of three species in the mallow botanical family (Malvaceae). Of the three species, "Malope trifida" is often used as an ornamental plant. Context_4 : Sempervivum altum is a species of flowering plant in the family Crassulaceae, native to the Caucasus Mountains. Like other members of the houseleek genus, it grows succulent leaves in rosettes. The rosettes of "S. altum" are 1-5cm across, and the leaves are pubescent or pilose. The flowers are pink edged with white, with yellow anthers, growing on a stem 30-40cm tall. The species was described in 1936 by William Bertram Turrill based on specimens collected by P.L. Giuseppi in a 1935 expedition to the Caucasus Mountains. It is closely related to "S. ingwersenii" and "S. ossetiense" from the same region. s of June 2013 , the name is not accepted by the World Checklist of Selected Plant Families. fact_1 : Sempervivum (Brit. fact_2 : , U.S. sem-per-VEE-vum) is a genus of about 40 species of flowering plants in the Crassulaceae family, commonly known as houseleeks. fact_3 : Other common names include liveforever (the source of the taxonomical designation "Sempervivum", literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. fact_4 : Malope is a genus of three species in the mallow botanical family (Malvaceae). Answer: Sempervivum
