Chlorospatha mirabilis (Mast.) Madison

Material examined. Middle slopes on W side of Cerro Pirre; 07°57′N, 077°46′W; 550–760 m; 28 Jun. 1988; T. B. Croat 68888 ( MO).

Identification. Chlorospatha mirabilis is characterized by its terrestrial habit, milky sap, trilobed or tri- sect leaves, usually maculate, long inflorescences, and spadices with a very long sterile region (approximately one-third of the total). By the combination of characters mentioned, this species has no similar species on Cerro Pirre, although in the field could be confused with Philodendron tripartitum (Jacq.) Schott , which differs by having colorless or reddish latex and fused stamens as synandria.

Distribution and ecology. Colombia, Ecuador, and Panama. In Panama, the populations of this species are found only in Darién Province. The collection data from the only specimen of Cerro Pirre indicate that it grows in the evergreen forest, between 550 and 760 m. During the samplings it was not possible to observe individuals of this species.
