KEY FOR DETERMINING VERMONT SHRUBS AND WOODY 



VINES^ 



PBEa'AEED BY F. V. RaND 



1. Vines, i. e. stems climbing, creeping or trailing; not self- 

 supporting 2 



1. Shrubs, i. e. stems erect or reclining 11 



2. Climbing over some support 3 



2. Stems trailing or creeping on the ground 7 



3. Climbing by twining stems 4 



3. Climbing by tendrils situated opposite the leaves 6 



3. Climbing by roots produced wherever the stem touches a 



proper support Poison Ivy, p. 128 



3. Climbing by leaf-stalks clasping support. . . .Virgin's Bower, p. 80 



3. Climbing by simply growing over the support. 



Climbing Nightshade, Solanum, p. 147 



4. Leaves opposite, i. e. 2 at each joint or node of the stem. 



Glaucous Honeysuckle, p. 180 



4. Leaves alternate, i. e. one at each joint or node 5 



5. Leaves pinnately veined, margins toothed. 



Bittersweet, Celastrus, p. 132 



5. Leaves palmately veined, lobed, with margins otherwise en-

6. Leaves simple Grape, p. 137 



6. Leaves compound Virginia Creeper, p. 140 



^ Since the method of using a "key" like the above may not be 

 clear to all, a word of explanation is added. Its purpose is to aid in 

 determining the name of any strange Vermont shruD or woody vine. 

 Suppose the unknown plant before you is a woody vine as character- 

 ized in the first line under "1" at the head of the "key"; you should 

 then pass down to "2." Next note its habit; if its stems tend to climb 

 over the support rather than to trail or creep on the ground you 

 should pass on to "3" below. Here you must decide between the five 

 types described. Suppose it climbs by roots produced wherever the 

 stem touches a proper support such as the bark of a tree, you have 

 the Poison Ivy and should turn to p. 128, for fuller description. If, 

 however, it climbs by the leaf-stalks clasping the support, it is the 

 Virgin's Bower and is described on p. 80. If, on the other hand it 

 has tendrils, you must pass on to "6," where, according to character of 

 leaf, you learn that your vine is either a Wild Grape or a Virginia 

 Creeper.
