It grows epiphytically at approximately 1,600 m elevation in a cloud forest ecosystem that is increasingly threatened by deforestation, land-use change, and mining activities. Due to its restricted distribution and the ongoing degradation of its habitat, we recommend classifying it as Critically Endangered according to IUCN Red List criteria.<\/jats:p>","DOI":"10.3897\/phytokeys.263.159826","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T13:32:09Z","timestamp":1758720729000},"page":"151-164","source":"Crossref","is-referenced-by-count":0,"title":["Porroglossum hildeae sp. nov.
