Manfreda longiflora is a species of flowering plant in the family Asparagaceae that is native to the Lower Rio Grande Valley of Texas in the United States and northern Tamaulipas in Mexico.[1] Common names include Amole de Río, Longflower Tuberose, and Runyon's Huaco.[4] The type specimens were sent by botanist and photographer Robert Runyon (1881–1968) to the New York Botanical Garden in 1921. Consequently, the species was initially placed in a monotypic genus named in his honour, Runyonia, by Joseph Nelson Rose.[5] M. longiflora is a rhizomatous perennial with 3–7 prostrate leaves in a basal rosette.[6] It inhabits hills, terraces and slopes in the semi-arid Tamaulipan mezquital.[7]
