The herbaceous flora in the thicket was the most complicated of 

 the three groups. . It exceeded the other groups in number both of 

 individuals and of species. It far exceeded the corresponding group 

 in the woods. It began with a conspicuous vernal flora followed by 

 a less well-defined early and late summer series and ended with a 

 distinct and showy autumn group. The spring flowers included 

 many of those found in the woods at this time such as Clayfoiiia vir- 

 ginica, Erythronhim anicricanum, Geranium maculatnm, and Anemone 

 qninquefolia with the addition a little later of tinker's weed (Trios- 

 teiim pcrfoliatum) and cinquefoil (Pofcntilla canadensis). The lit- 

 tle Potentilla remained after the other spring flowers had gone and 

 its creeping stems with a few grasses and an occasional dewberry 

 (Rubus z'illosus) covered the floor of the thicket throughout the grow- 

 ing season. Among the early summer flowers that followed the 

 spring group were the primroses Oenothera pumilla and O. pratensis, 

 loosestrife (Lysiniacliia qiiadrifolia), a very important but inconspicu- 



Insects of the Woods (No. Species).
