Echeandia is a genus in the Anthericaceae family. The Angiosperm Phylogeny Group II, 2003 suggests that this genus could optionally be included in the Agavaceae or Asparagaceae family. Plants in this genus are closely related to Anthericum and are perennials growing from corms with enlarged storage roots. Echeandia has fused stamens whereas Anthericum has spreading/free stamens. There are around 80 species occurring from the southwestern United States through central America to South America, with the majority of the species from Mexico. Flowers are usually yellow.
Echeandia formosa occurs from southeast Mexico to central America. The plant photographed below by Alessandro Marinello was collected in Guatemala at Agua Volcano at 2500 meters.
Echeandia parviflora is native to central Mexico to Guatamala. The photos below were taken by Dale Denham-Logsdon in Mexico near Ixtapan de la Sal, Estado de Mexico, where it blooms in late summer.
