 small almost sessile flowers ; lip 3-lobed or halberd-shaped at base: fl. sprini_ r . 



C. Odontorhiza. Rich woods, common only S. : 6'- 16' high, thickened

 flowers early summer, scentless. 



C. parviflorum, SMALLER YELLOW L. In similar situations ; stems and 

 leaves generally smaller, and flower about half the size of th" other, somewhat 

 fragrant, the sac broader than high, deep yellow, and the lance-ovate sepals 

 browner.
