Since a revision of Triodia R.Br. was published some years ago (Burbidge 1953) several new species have been collected and facts concerning the distribution of others have been accumulated. Two new species and one variety are described here from plants obtained in central Australia. Two new species from the North West Division and one from bhe Kimberley Division of Western Australia are also described. The opportunity is taken to discuss the circumscription of a few species and the distribution of others formerly known only from type material.

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
