Agave longiflora ( synonym 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. [3] 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. [4] The species has been placed in the genus Manfreda, now absorbed into Agave. A. longiflora is a rhizomatous perennial with 3–7 prostrate leaves in a basal rosette. [5] It inhabits hills, terraces and slopes in the semi-arid Tamaulipan mezquital. [6]
