Common Name The Leopard Spotted Hooked Epidendrum [refers to the spotted flower and the lateral lobes of the lip]

Flower Size .6" [1.5 cm]

Found in Antioquia and Tolima departments of Colombia on the Cordillera Central in wet montane forests at elevations of 2100 to 2250 meters as a miniature to just medium sized, cold growing epiphyte with a simple, erect, cane-like, terete stem carrying 1 to 6 on the primary stem, 1 to 2 on the successive stems, alternate, all along the stem, green, progressively larger, tubular, membranous, pale green leaf sheaths, blade, oblong, apex unequally bilobed, unequal, progressively larger, coriaceous leaves that blooms in the later spring to early winter on a terminal, through a blong, laterally compressed, sides parallel spathe, peduncle 3.2 to 4.8" [8 to 12 cm]long, erect to arching, racemose, 10 to 44 flowered inflorescence with much shorter than the ovary, triangular, acute floral bracts carrying flowers with the lip always oriented towards the apex of the rachis.

"Epidendrum leopardihamatum belongs to the GROUP Mancum SUBGROUP Stenoglossum which is characterized by the terete stem with 1 to 2 apical leaves, the narrow elongate spathe, the inflorescence erect to arching, with numerous flowers with the lip always oriented towards the apex of the rachis, and the lip usually 3-lobed, lateral lobes small, strongly falcate, hamate, and mid-lobe long, narrow, forming an upward arch and apically dilated into a triangular or rhomboid apex. This new species has green flowers totally covered by brown dots, the column light yellow-green, with a few brown dots at the apex. It has been confused with the rare Epidendrum hamatum (Garay) Dressler which is vegetatively very similar but the flowers are white slightly tinged pink, with rose dots at the apex of the column and base of the lip, and is endemic to north of Bogotá, Cundinamarca, and Boyacá in the Cordillera Oriental. The better-known species is Epidendrum coryophorum (Kunth) Rchb.f. which differs in having a simple lip and deep purple flowers with occasionally with the apices of the sepals white. Epidendrum machinense M.F.Escal. & Rinc.-González is vegetatively similar, with flowers with yellow corolla stained purple-brown with yellow apices and a white lip and a column with numerous wine-red spots."

"NOTE: This species was incorrectly published as Epidendrum hamatum by Domínguez & Hágsater (Species Orchidacearum 3(1): 28 2019). It was also used to compare with Epidendrum machinense by Rincón-González & Escalante (Phytotaxa 2020: 38, fig. 4C). The specimen of Ortiz 4184 was cultivated at Santandercito (Cundinamarca) and said to have come from Abriaquí, has pale yellow flowers without any brown dots. It may correspond to another entity, or maybe a misplaced label." Hagsater etal 2021
