VALENZUELA GAMARRA, Luis. A new species of Brachionidium (Pleurothallidinae: Orchidaceae) from The High Montane Forest in The Central Jungle of Peru. Lankesteriana [online]. 2017, vol.17, n.2, pp.113-118. ISSN 1409-3871.  http://dx.doi.org/10.15517/lank.v17i2.29710.

A new species of Brachionidium was found on the highest mountains of the Central Jungle of Peru, on a wet Puna forest at 3470 m altitude. This species is similar to B. loxense and B. diaphanum but can be distinguished by its elliptic leaves with petioles 3-4 mm long; the short erect floral peduncle 2-3 mm long; the pink translucent sepals, red-wine toward the base; the floral bract spatuliform 15 × 5 mm; lip red-wine, bimarginated, trapezoidal, small, fleshy, obtuse acuminate, slightly prolonged lateral lobes antrorse and straight with a strongly pubescent cordate callus, split towards the apex.

Keywords : Brachionidium; Central Jungle of Peru; Epidendreae; New species; Pleurothallidinae; Pui Pui Protection Forest; Wet puna forest.
