Setiechinopsis
Echinopsis is a genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. As of November 2025, Plants of the World Online used a broad circumscription of the genus, resulting in about 80 accepted species, ranging from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines.
They are known for their big size, length of tube, and beauty of their flowers, borne upon generally small and dumpy stems.
