9. Habenaria repens Nutta//, Gen. No. Amer. PI. 
2 (1818) 190. 
This is one of the most common and widely ranging 
species of Habenaria. It has been reported from the south- 
ern United States (North Carolina to Florida), Mexico, 
British Honduras, Guatemala, Nicaragua, Costa Rica, 
Panama, the West Indies and South America. 
A striking peculiarity of this species is its adaptation 
to life in wet places. Again and again it is reported as 
being associated with aquatic plants or floating vegeta- 
tion. Mr. Edwards found his specimens associated with 
floating plants in Lake Yojoa or in very wet ground. 
In Hooker’s Icones Plantarum, ser. 4, 7 (1901) t. 2686, 
R. A. Rolfe referred to it as being aquatic or subaquatic, 
and in The Plant World 6 (1908) 165, Roland M. Harper 
reported it from Georgia where he found specimens sup- 
ported on floating masses of the water-hyacinth (J7ich- 
hornia crassipes) in water six feet deep. In response to 
its adaptation to wet surroundings, H. repens develops 
a copious root-system without tuberoids.
