precisely alike, a comparison of all, with the plants, leaves no doubt but H. limosa 

 that the specimens were collected at one time and place. All the specimens 

 are in early fruit. Wright's are accompanied by a label on which is printed 

 "C. Wright, Coll. N. Mex., 1851-2," but the sheet in the Gray Her- 

 barium is annotated as above. Some sheets of this number are not an- 

 notated, so, naturally, they have been referred to New Mexico by Dr. 

 Rydberg.

^"GYMNADENIA longispica sp. nova, (specimen cui folia radicalia desunt.) Scapo 

 gracili erecto, fere pedali ; foliis 4 infra spicam, parvulis, bracteiformibus, ovato-lanceolatis ; 

 spica circiter 50-flora, gradatim ad apicem gracilescenti, 7" longa, bracteis lanceolatis, 

 ovaria tequantibus ; floribus minimis, albis? in sicco fuscantibus; coroUis cernuis, sepalis 

 subaequantibus, labio integro, calcare tenui, clavato, ovario longiori. 



"The spike is very long, tapering, with at least fifty flowers. Sepals and petals almost 

 equal, lip entire, spur longer than the germ, filiform, clubshape, with a much longer spike 

 than Spiranthes bracteosa of Lindl. in Bot. Reg. t. 1934, to which Gymnadenia longispica 

 has a great resemblance. The inflorescence seems spirally twisted round the scape." Du- 

 rand, loc. cit.
