摘要

在厄瓜多尔西北部洛斯塞德罗斯保护区的兰花丰富的森林中发现了两个新的Platystele物种。许多种类的兰花生长在这些森林中，有些是特有的。柏树Platystele cedriensis与P. rhinocera相似，不同之处在于其水平到下降的花序和三脉背萼片。Platystele decxii呈现的花朵具有独特的心形唇，唇的叶片上有心形凹陷。我们警告说，正在进行的采矿活动和特许权将危及这些物种和其他洛斯塞德罗斯保护区的特有物种。关键词:石竹，兰科，柏树，桐叶，同域种

Two new species and new records of Platystele (Pleurothallidinae: Orchidaceae) from Los Cedros Reserve in Ecuador

Two new species of Platystele were discovered at the orchid-rich forest of Los Cedros Reserve at North-west Ecuador. Many species of orchids grow in these forests and some endemic to it. Platystele cedriensis is similar to P. rhinocera from which it differs in the horizontal to descending inflorescence and the three-veined dorsal sepal. Platystele decouxii presents flowers with a unique heart-shaped lip with a heart-shape depression in the blade of the lip. We warn that on-going mining activities and concessions put in risk these and other endemic species from Los Cedros Reserve. Key words: Carchi, Orchidaceae, Platystele cedriensis, Platystele decouxii, sympatric species
