"Amaryllis" is also used in the name of some societies devoted to the genus "Hippeastrum". List of plant species in the genus Hippeastrum. He also renamed "Rhodolirium andinum" as "Hippeastrum rhodolirion". "Hippeastrum pardinum" from the Andes. At one stage, "Habranthus" was considered a subgenus of the closely related "Hippeastrum". At one stage, "Rhodophiala" was considered a subgenus of the closely related "Hippeastrum". John Gilbert Baker considerably reorganised "Hippeastrum". Species in the genera "Allium", "Hippeastrum", "Narcissus", and "Tulipa" all have tunicate bulbs. Terrestrial bulbous perennial herbaceous plants, although three species of "Hippeastrum" are epiphytic. For early treatment of "Rhodolirium", see Taxonomy of Hippeastrum. Other species such as "Hippeastrum reticulatum" are self-pollinating, reproducing by distributing seed. "Rhodophiala" species resemble small-flowered "Hippeastrum" or multiflowered "Habranthus" species. Herbert's fourteen species included this "Hippeastrum equestre". Herbert proposed to call the genus, which he distinguished from Linnaeus' "Amaryllis", "Hippeastrum", or "Knight's-star-lily". Brazil also produces 17 million "Hippeastrum" bulbs annually.
