ameter. The leaves of H. Brittonae are little more than 
reduced, clasping, equitant sheaths, whereas those of 
Hi. alata are rather large, broad and prominent. ‘The spur 
of H. Brittonae is almost constantly 9 mm. long, whereas 
the spur of H. alata averages about 11 mm. in length. 
It is interesting to note that sufficient material of this 
rare species was recently obtained in Cuba ( Hodge, 
Howard & Godfrey 4761) to produce a number of 
Plantae Exsiccatae Grayanae. 
This species is apparently endemic to Cuba.

An examination of a photograph of the type of HZ. 
palustris in the Ames Herbarium (No. 58600) and a 
study of the original description reveals that it is refer- 
able to HZ. repens. 
Habenaria repens grows in ditches, streams, swamps, 
ponds and on lake shores and is often found on floating 
weed mats on the surface of the water. It is also found in 
miry meadows, fresh-water marshes and bogs. ‘The name 
(palustris) implies growing in this type of habitat and
