(A) Pogonia; Snake-mouth (Pogonia ophioglos- 
soides). Snake-mouth is delicate, pure pink in color 
and slightly fragrant. Its pollen is not in stemmed 
masses but is showered on the back of a visiting insect 
as he backs out of the flower. The stem is from 8 to 
13 inches high, bearing at its top a single flower; sepals 
and petals are similar in shape; the lip is spatulate, 
prominently crested with yellow and white, and toothed 
and lacerated. About midway of the flower stem is a 
single oval leaf and just below the flower is a smaller 
bract-like one. Pogonia grows in swamps from New¬ 
foundland to Minn, and southwards to the Gulf of 
Mexico, flowering during June and July. 
(B) Nodding Pogonia (P. trianthophora) has a leafy 
stem from 2 to 8 inches high. From two to eight small 
oval leaves alternately clasp the stem; the flowers, 
which number from one to six, appear singly from the 
axils of the upper leaves, nodding on slender peduncles; 
they are small, magenta-pink and with ovate, tliree- 
lobed lips. It is locally distributed from Me. to Wise, 
and southwards.
