description_en: Genus of 50-120 species of sometimes shrubby or tree-like, perennial cacti occurring in South America, in habitats ranging from lowland deserts to upland dry scrub. They have mainly spherical stems with straight ribs and spiny areoles. Large, trumpet-shaped to almost bell-shaped flowers are produced laterally or near the ends of the stems from spring to summer. On species native to mountainous regions to 3,000m (10,000ft) high, the flowers are white, yellow, red, purple, or pink, and open during the day; on plants that grow naturally at much lower altitudes, the flowers are mainly white or pale pink, and open at night. In frost-prone areas, grow as houseplants or in a temperate or warm greenhouse. In warmer areas, grow in a desert garden.
hardiness_en: Frost tender.
cultivation_en:
propagation_en: Sow seed at 21°C (70°F) in spring, or remove offsets in spring or summer.
pests_en: Spherical species are particularly prone to mealybugs.

comment_ja: 分子系統以前、20世紀末は1970年代以降の行き過ぎた属の分割の反省から広義のEchinopsisが受け入れられていた。近年、トリコセレウス亜連の分子系統が明らかになるにつれ、広義のEchinopsis内のクレードを改めて属として認める傾向にあり、POWOではSchlumpberger & Renner (2012) に基づき、Acanthocalycium, Arthrocereus, Denmoza, Echinopsis s.s., Harrisia, Leucostele, Lovibia, Reicheocactus, Setiechinopsis, Soehrensia, Trichocereus とCleistocactus, Oreocereus の多くの近縁属を認めている。この体系だとEchinopsis s.s. は21種のみになる。ところが、学名の安定性の観点からAnceschi (2013) のようにParodia と同様に広義のEchinopsis とする方がいいという意見もあり、最近ではRomeiro-Brito et al. (2023) はトリコセレウス亜連をEchinopsis (Acanthocalycium, Denmoza, Leucostele, Lobivia, Setiechinopsis, Soehrensia, Trichocereus を含む) とその他16属にまとめている。
