the roots, as shown in the photograph, are produced 
along a central axis as in HZ. repens. 
This species occurs from Virginia to Florida along the 
Atlantic seaboard, along the Gulf Coast to Louisiana 
and ‘Texas, throughout Central and South America and 
the West Indies.

Habenaria replicata 4. Richard in Sagra Hist.

Acuna (p. 17) included Habenaria (Gymnadeniopsis ) 
nivea (Nutt.) Spreng. in his flora, based on a report of 
this species having been found in Cuba. I have seen no 
material of this species from outside the United States. 
The report of its being in Cuba was based on a collection 
of H. replicata, a plant which simulates H. nivea very 
closely in habit. Habenaria replicata commonly has a 
loosely flowered, somewhat secund raceme and a lip 
which is angled or lobulate near or just below the middle, 
whereas HT. nivea commonly has a densely flowered, 
cylindrical-conical raceme and a lip which is not angled 
nor lobulate at the middle but is rather dilated above the 
middle. 
It is interesting to note that sufficient material of this 
rare species was recently obtained in Cuba ( Hodge, 
Howard & Godfrey 4777) to produce a set (1088) of 
Plantae Exsicecatae Grayanae. 
This species is apparently endemic to Cuba.
