Epipactis dolabripetala Ames Orchidace^, Fasc. ii. p. 262 



(1908). 



Related to E. striata (Reichb. f.) A. A. Eaton. Plant erect or 

 ascending, 3 dm. high from an elongated creeping thickened 

 rhizome. Leaves about 4 in number, approximate near the base 

 of the stem; lamina lanceolate, acute, 3-5 cm. long, 1.4-2 cm. 

 wide ; petiole slender at the base of the lamina, scarious, dilated 

 and sheathing where it joins the stem, 7-14 mm. long. Peduncle 

 slender, finely pubescent, clothed with 4 oblong acute hracts^ 

 the lowermost of which are sheathing at base. Raceme somewhat 

 cylindraceous, rather loosely flowered, 7 cm. long; rhachis finely 

 pubescent. Floral bracts lanceolate, acuminate, acute, sparsely 

 hairy, equalling the sparsely hairy ovaries, or shorter than the 

 ovaries of the uppermost flowers. Lateral sepals 4.5 mm. long, 

 1 -nerved, lanceolate. Upper sepal narrower than the laterals, 

 1 -nerved, 4.5 mm. long. Petals dolabriform, 1 -nerved, about 

 5 mm. long. Labellum 4.5 mm. long, ovate-lanceolate, slightly 

 saccate at base, with several minute, thickened hairs within the 

 sac. 



Mexico : Collected near San Cristobal in Chiapas, at an altitude ranging 

 between 7000 and 8800 ft., September 18, 1895, by E. W. Nelson (no. 

 3211). Type in U. S. National Herb. 



The type is composed of a single specimen preserved in the 

 United States National Herbarium, from which the accompany- 

 ing illustration was prepared. In accordance with the view held 

 by A. A. Eaton,* I have adopted the generic name Epipactis of 

 Boehmer for those species which have been heretofore impro- 

 perly placed in the genus Goodyera of R. Brown.
