Hemp, Andreas conservation suggestions Critically Endangered endemism new species Nguru Mountains Polystachya nguruensis threats amenazas endemismo Montañas Nguru nuevas especies peligro crítico Polystachya nguruensis sugerencias de conservación Polystachya nguruensis, a new endemic species from the isolated Nguru Mountains of eastern Tanzania, is described here, and its affinities and conservation status are discussed. Polystachya nguruensis differs from P. lukwangulensis in having much longer, more obviously several-noded pseudobulbs, shorter, narrowly oblong-elliptic, coriaceous leaves, and a longer, more densely many-flowered, branching inflorescence with smaller flowers and ecallose lip with a narrowly oblong a midlobe with a broadly obovate to subcircular, apiculate, lip midlobe. Unlike most allied species, it is a lithophyte, growing on sloping slabs of crystalline rock, a highly vulnerable habitat that has already been partly destroyed by fire. Consequently, it is assessed to be Critically Endangered and in need of immediate conservation attention.
