03CB87DFD102FFA6FF42F8C8FBFCF913.taxon	discussion	Discussion: — Stelis stephanii belongs to section Stelis, which is characterised by the widely spreading and equally sized sepals (Luer 2009). It may be related to the species complex of Stelis argentata Lindley (1842: 64), which is documented from Bolivia as well. Stelis stephanii differs from species of this complex in the triangulate lip and the partially pubescent sepals. The lip of Stelis stephanii is unusually long and papillous, in the complex of Stelis argentata the lip is transversely subquadrate (Luer 2009). In the complex of Stelis argentata the hairs are on the whole sepal or absent and shorter than those of Stelis stephanii which are there only on the margins of the sepals. With its total height of about 14 – 20 cm, the new species is relatively large for the genus Stelis, but in some species of Stelis size can vary markedly.	en	Steudel, Bastian (2011): A new species of Stelis (Pleurothallidinae, Orchidaceae) from South Yungas, Bolivia.
