PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus spiralis aff. green bract Huanuco
FORMAL SCIENTIFIC NAME:
This form appears to match the type specimen of the plant Ruiz named as Costus laevis, which he collected at Chacahuasi, near Cuchero, Peru in 1787 and shipped to Spain. It does NOT match Ruiz' written DESCRIPTION of the plant he named as Costus laevis. It best fits the currently described Costus spiralis in a green bract form seen throughout the eastern foothills of the Andes in Peru.
