BUGLE-WEEiX 



Lycopus Virginicus. Mint Family. 



Stem. Six inches to two feet high; obtusely four-angled. Flowers. 

 Much as in above. Calyx-teeth. Usually only four ; barely pointed. 



The bugle-weed is found in wet places across the continent. 



WHITE VERVAIN. 



Verbena urticafolia. Verbena Family. 



Three to five feet high. Leaves. Oval ; coarsely toothed. Flowers. 

 Small ; white ; in slender spikes. 



It almost excites one's incredulity to be told that this unin- 

 teresting-looking plant, which grows rankly along the highways, 

 is an importation from the tropics, yet for this statement the 

 botany is responsible. 



TRAVELLER'S JOY. VIRGIN'S BOWER. 



Clematis Virginiana. Crowfoot Family. 



Stem. Climbing ; somewhat woody. Leaves. Opposite ; three-divided. 

 Flowers. Whitish ; in clusters ; unisexual. Calyx. Of four petal-like se- 

 pals. Corolla. None. Stamens and Pistils. Indefinite in number; oc- 

 curring on different plants. 



In July and August this beautiful plant, covered with its 

 white blossoms and clambering over the shrubs which border the 

 country lanes, makes indeed a fitting bower for any maid or 

 traveller who may chance to be seeking shelter. Later in the 

 year the seeds with their silvery plumes give a feathery effect, 

 which is very striking. 



This graceful climber works its way by means of its bending 

 or clasping leaf-stalks. Darwin has made interesting experi- 

 ments regarding the movements of the young shoots of the 

 Clematis. He discovered that, "one revolved, describing a 

 broad oval, in five hours, thirty minutes ; and another in six 

 hours, twelve minutes; they follow thr course f the sun."
