distinguish it.

Hab. in Carolina; ripis lutosis inundatis fluvii Neuze, prope Newbern,

(hab. s. sp.) : 
The largest and finest Spiranthes in the United States, possessed of a 
very sensible and delicate fragrance. 'The flowers white, slightly inclin- 
ing to green. The root runs considerably, and possesses very thick 
branching fibres. The leaves are also very long and numerous ; the 
bracts nearly the length of the flowers, and sharply acuminate ; the lip 
entire and delicately edged with a slender curling fringe. It flowers late.
