parted, one-fourth to one-half of an inch broad, the segments fan-shaped 



and copiously fringed, the fringe of the middle segment shorter than that 



of the lateral ones; spur somewhat thickened at the tip, about three-fourths 



of an inch long, and longer than the ovary. 



In meadows, swamps and wet woods, Newfoundland to Minnesota, 



North Carolina and Tennessee. Flowering in July and August. 



The Large or Early Purple-fringed Orchis (Blephariglottis 

 grandiflora (Bigelow) Rydberg) has a large, dense raceme of lilac or
