Stem slender, 2-3 dm. high : tubers narrowly fusiform, about 

 5 mm. thick : leaves linear, about 1 dm. long and 8-10 mm. wide, 



acute : spike slender, lax ; bracts lanceo- 

 late, acuminate ; the lower longer than the 

 flowers : flowers pure white, very fragrant : 

 upper sepal ovate-lanceolate, obtuse ; the 

 lateral ones linear-lanceolate, acutish, 

 strongly veined : petals narrowly linear- 

 lanceolate, equalling the sepals ; lip lanceo- 

 late with an ovate-rhomboid base, about 5 

 mm. long ; spur filiform, not at all clavate,

Closely resembling the variety of preceding species, it is dis-
