Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally (along one side). The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are x= 8-13, 17, and higher. All the species in this tribe presents a remarkable aesthetic interest and horticultural value.1]
It includes two subtribes:
subtribe Zephyranthinea - includes species of small height with solitary flowers. Inflorescence bracts are fused forming a tube surrounding the pedicel of the flower. Genera in this subtribe are
Sprekelia, Habranthus, Cooperia, and Zephyranthes.
The plant genus Calandrinia contains many species of purslane, including the redmaids. The genus was named for Jean Louis Calandrini, an 18th century Swiss botanist. It includes around 150 species of annual herbs which bear colorful flowers in shades of red to purple and white. Plants of this genus are native to Australia, Chile, and western North America. [more]
Hippeastrum is a genus of about 90 species and 600+ hybrids and cultivars of bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae, native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean. Some species are grown for their large showy flowers. For many years there was confusion amongst botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of this genus, which are widely used as indoor flowering bulbs. The generic name Amaryllis applies to bulbs from South Africa, usually grown outdoors. [more]
