#arthrocereus

• Arthrocereus — A genus of succulent plants in the Cactaceae family, endemic to the mountainous and arid regions of Brazil, particularly in the state of Minas Gerais. These species are structurally characterized by thin, cylindrical, poorly branched or decumbent stems, covered with dense and fine spines, producing large, nocturnal, white or pale-pink flowers adapted for pollination by moths.
• Arthrocereus microsphaericus — The scientific name of a rare and endangered cactus species belonging to the Arthrocereus genus, found exclusively in the mountainous regions of eastern Brazil. The plant is structurally recognized by its very small globular or cylindrical segments (hence the name 'microsphaericus'), with reduced spines, forming compact clumps at soil level and bearing major ecological importance in biodiversity conservation.
