ORCHIDACE^ 



lumna 2 mm. alta, valde arcuata, utrinque prope apicem breviter 



alata. Anthera antice truncata. 



In habit similar to L. cyclostele Schltr. and L. gibbosa Finet. 



From L. propinqua Ames it differs conspicuously in the form 



of the labellum and petals. Liparis Amesiana Schltr. is very 



similar in habit, but is clearly set apart by the cuneate labellum 



which is much broader at the tip than at the middle.
