VINES AND SHRUBS 



lobes tipped with a bristle. Thickish and gray underneath- 

 Acorns considerably taller than the cup, maturing the second year. 

 An irregularly branched shrub, without beauty, often 

 found growing in large numbers in burned-over ground. In 

 sandy, sterile soil. Maine to Ohio, southward in the moun- 

 tains of Virginia and Kentucky. 



Common Hop 



Humulus Lupulus ("a little wolf," because it grows among and 

 twines around willows and chokes them as a wolf does a flock of 

 sheep). — Family, Nettle. Color, green. Flowers, of two kinds, 

 the staminate in loose racemes or panicles, with a calyx of 5 

 sepals. The pistillate flowers grow in short, roundish spikes, 2 

 beneath a single, broad, thin calyx-leaf or fruiting-bract. These 

 bracts, closely grouped and overlapping one another, become the 

 scales of the hop-fruit or strobile. Fruit, an achene. The calyx 

 bears resinous dots, which give the hop its special bitter flavor and 

 odor. Leaves, opposite, serrate, deeply 3 to 7-lobed below, becom- 

 ing alternate and entire above; on long petioles, 1 to 3 inches, with 

 stipules. Fruit ripe in September and October. July and August. 



The soporific hop-vine, useful in making yeast and malt 

 liquors, is familiar both as a wild and cultivated vine. The 

 young shoots have been cultivated and eaten like asparagus. 

 Nova Scotia to New York, southward along the mountains 

 to Georgia, westward to the Rocky Mountains in thickets 

 and along streams. 



Climbing False Buckwheat 



Polygonum sczndens. — Family, Buckwheat. Color, yellowish 

 green, heaves, heart or halberd - shape, pointed, 1 to 6 inches 

 long, with petioles and conspicuous sheaths. Calyx, 5-cleft, the 

 3 outer divisions reflexed in fruit. Stamens, 8. Stigmas, 3. 



A loose, straggling sort of vine, with small, dull flow r ers on 

 long pedicels in loose racemes. The fruit, an achene, hangs 

 loosely from the older flowers. In woods and thickets from 

 Nova Scotia to Florida and westward. 



Crested False Buckwheat 



P. cristktam is a more slender, twining species, 12 to 20 inches 

 long. Leaves, triangular, with rather sharp basal angles and 

 pointed apex, long-petioled. Flowers, generally in leafless racemes
