New species of Epidendrum (Orchidaceae: Laeliinae) from Caquetá, Colombia

The Andean and Amazonian forests of Colombia are renowned for their high biodiversity, with nearly 2500 orchid species in the Andes and 355 species in the Amazon. We propose and describe two new species of Epidendrum from Caquetá, Colombia: one from the cloud forests on the eastern slopes of the Andes, and the other found on trees in a city park in Florencia. Epidendrum fernandoi resembles E. rocioae, from which it differs by tall (11.7–17.0 vs. 25 cm), narrowly ovoid subterete pseudobulbs (vs. cylindrical to oval), smaller flowers ovary shorter (3.3 vs. 10–17 mm long).

Epidendrum mambe resembles E. platypetalonocturnum, from which it differs by petals (35–36 × 4.8–5.0 vs. 40–42 × 9–10 mm) and sepals (36–37 × 6.4–7.6 vs. 40–44 × 8.5–9.0 mm) shorter and narrower, the longer (24 vs. 18.5 mm) and narrower (1.8–1.9 vs. 2.3–3.0 mm) central lobe of the lip, and the longer calli (8 vs. 4–5 mm).
