Congea and Sempervivum, are which type of items?
Sempervivum 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.
Seletracetam Seletracetam (UCB 44212) is a pyrrolidone-derived drug of the racetam family that is structurally related to levetiracetam (trade name Keppra). It was under development by UCB Pharmaceuticals as a more potent and effective anticonvulsant drug to replace levetiracetam but its production has been halted.
