ONAGRACEAE 
Epilobium augustifolium L. Chamaenerion augustij olium (L.) Scop. Fireweed, 
Willow-herb. 
Abundant in open woods, clearings, prairies, and burned areas through- 
out the region. It appears very soon after clearing and burning, and sup- 
plies a blaze of colour to what would otherwise be a dreary aspect. Young 
shoots common during most of June, and buds late in June or early in July. 
The first flowers usually appear during the first week in July, but the 
height of the flowering season is in the latter part of July and early August. 
Poultices made from the rootstocks are said to have healing qualities.
