9C973EBED0A55E4A97FBD05C43D3D8E9.taxon	distribution	Distribution and ecology. This species inhabits the cloud forests around the river Utcubamba in the province of the same name in the district of Bagua Grande. This area is known as " El Higueron " and is legally administered by the Rafael Cotrina family. This family, together with that of the third author, are conducting research and conservation programs about the yellow-tailed woolly monkey Lagothrix flavicauda Humbolldt and its habitat in the PCA BF. Flowers have been recorded in March and April. Liparis sessilis inhabits the understory rich in mosses, rocks and old stems of Anthurium Schott and Psychotria L. species. Also, this species has been using Palicourea shrubs as its phorophyte and can reach up to 2 m above ground. The roots of Liparis sessilis are poorly developed and the stems turn white or brownish as the younger parts of the plant grow. According to recent observations (Rimarachin pers. obs.), the population of this species is small. Indeed, it has only been found in a degraded area and in two other zones of primary forest. The species has been propagated from cuttings and is currently being grown in the PCA BF.	en	Damian, Alexander, Salazar, Gerardo A., Rimarachin, Leyda (2020): A new species and a new record of Liparis sect.
