Habenaria ciliaris var. alba Morong, Bull. Torr. Club, 
20: 38. 1893. 
Stems and leaves similar to those of the preced- 
ing species. Spikes densely or rather loosely 
many-flowered; flowers pure white, usually a little 
smaller than those of H/. ciliaris; lip narrower, 
oblong; petals toothed or somewhat fringed at the 
apex ; fringe of the lip copious or sparse.

and New Jersey. Intermediate forms between this and 
the preceding species, with light yellow flowers, are 
probably hybrids. Blooms a few days earlier than 
ciliaris where the two grow together. July—Aug.
