CORALLORHIZA 143 



parallel reported it in one locality at an altitude of 7,000 feet. 

 Its wide-spread habitat shows that it has held its own in spite 

 of its leafless condition. Doubtless its every attraction of 

 spur and spots and stripes serves to make it the most con- 

 spicuous and the best adapted of its kind, hence from July 

 until September it may be found rather commonly in woods 

 from one coast of the continent to the other.

This Coralroot is also large, growing from eight to 

 twenty inches in height. Its scape is stout and purplish, and 

 it bears from ten to twenty-five flowers on a raceme that 

 grows from two to six inches long. 



It is one of the three Coralroots whose flowers grow

 are of a dingy purple hue streaked with lines of true purple. 

 The individual blossoms are often three-quarters of an inch 

 long, and the spreading lip, that hangs out a little longer

 ovary, and stands sharply erect, after the fruit ripens, and 

 the elliptical capsule, nearly an inch long, droops on the 

 stalk. 



On pulling off" the lip of one of these Coralroots and 

 examining it under the microscope, one will see a divided 

 ridge in the throat (Plate LIV., Fig. 4), lying between the
