GYNANDRIA MONANDRIA. 
507 
scurely nerved, terminating at base in a closed sheath. Flowers five to 
eight, in a terminal raceme. Bracteal leaves very small. Exterior segments 
of the perianth three, lanceolate, a little connivent, six to seven lines long, 
pale yellow tinged with purple; the two lateral interior segments cuneate, 
obovate, pale yellow, as long as the exterior, but more slender. Column 
more than half as long as the perianth, dilated; summit of the lip three- 
lobed. Pollinia four, near the summit of the tube, covered with an opercu- 
lum having four cells. 
Grows along the sea-coast of Georgia and Carolina, on the bark of trees, 
principally of evergreens. 
The most northern locality in which I have seen this plant is on Edings ? 
Island, at the entrance of Port Royal inlet. I found it there growing on the 
bark of the Magnolia Grandiflora, and sent it to Dr. Muhlenberg, who placed 
it in his catalogue as the E. Magnoliae. In passing to the south along the 
sea-coast, it becomes more common, and is found on several species of oak, 
and I believe on other trees. 
Flowers in August and September; probably through the whole summer.
