(A) Rattlesnake Plantain ( Epipactis pubescens) 
is a common orchid having beautiful leaves, radiating 
from the fleshy, creeping rootstalk. The scape is 6 to 
15 in. high and carries at its top densely flowered 
sepals and petals united to form a hood. It is found 
in the whole of the U. S., flowering in July and August. 
(B) Ladies Tresses (Spiranthes cernua) is so named 
because of the braided arrangement of its flowers. The 
leaves are few, grass-like, sheathing the scape near its 
base. The scape is 6 to 15 in. high, has several small 
bracts and ends in a 2 or 3-ranked spiral raceme of 
white or creamy flowers; petals and upper sepal joined, 
lateral sepals lanceolate; lip ovate-oblong with a rough 
tip. Common in moist fields or woods from Me. to 
Minn, and southwards. 
Slender Ladies Tresses (8. gracilis) is slender, has 
its flowers in a single-ranked 1-sided or slightly twisted 
raceme; lip green, with a white wrinkled margin. 
Leaves small, ovate basal. Found in dry ground from 
N. S. to Manitoba and southwards.
