Phaseolus costaricensis Freytag & Debouck (1996: 157) View in CoL [clade B; sect. Phaseoli DC emend. Freytag ]. TYPE: DG Debouck et al.2135 (HOLOTYPE: US-3168869 ; ISOTYPES: BR, CR-125599 , K, UC-1571112 ,USJ-30270).

This taxon was confused with P. coccineus in previous floras of Costa Rica and Panama ( Standley 1937 and Lackey & D’Arcy 1980, respectively), although several collectors noted the “bright crimson” or “brilliant fuschia” color of the corolla ( Fig. 2 View FIG ). It thrives in alder or oak humid montane forest at 1400–2200 m. Some populations seem already extinct because of the expansion of urban areas and coffee plantations: the one at Ochomogo found in 1896 by A Tonduz 10914 (US-472031) or the one of San Isidro de Coronado found in 1937 by PH Allen 555 (F-920349). Urbanization and the raising of vegetable crops of temperate climate also affect some populations in the ChiriquÍ province of Panama ( Debouck & RodrÍguez-Quiel 2020).
