272 CAPRIFOLIACEAE 



moist woods from Nova Scotia to Saskatchewan and south to 

 Connecticut and Minnesota. In Illinois, its occurrence is re- 

 liably known only for three stations, namely. West Pullman 

 and Wildwood in Cook County, and near the Des Plaines 

 River in Lake County. 



An additional species, L. sempervirens Linnaeus, is dubiously 

 reported on the basis of a few specimens taken at straggling 

 stations through the southern section of the state. The Japa- 

 nese Honeysuckle, L. japonica Thunberg, has escaped from 

 cultivation in several places, notably near Anna and Jones- 

 boro in Union County, near Pinckneyville in Perry County, 

 in Johnson County, and at Villa Ridge in Pulaski County. 



DIERVILLA (Tournefort) Miller 

 Bush-Honeysuckle 



The bush-honeysuckles are shrubs with simple, opposite leaves 

 and with yellow flowers borne singly or mostly in small terminal 

 or axillary cymes. There are 5 linear calyx lobes, and the petals 

 are united into a narrowly funnel-shaped corolla with 5 lobes 

 at the top. The 5 stamens are adnate to the corolla tube. The 

 ovary is 2-celled and develops into a linear-oblong, 2-valved, 

 many-seeded capsule, which opens by splitting along the septa. 



There are three species in this genus, all of them inhabitants 

 of the eastern United States. Only the following is native in 

 Illinois.

 Bush-Honeysuckle 



The Bush-Honeysuckle, fig. 72, is a low but erect shrub com- 

 monly 16 to 24 inches, or less often 3 feet, high with gray, 

 shreddy bark on old stems and green or often red-tinted branch- 

 lets, which are smooth or frequently puberulent in lines running 

 down from the nodes. The opposite leaves are ovate to lanceo- 

 late, mostly 2y2 to 6 inches long, and up to 2 inches wide, with 

 ciliate, rounded teeth on the margin. The blades are narrowed 

 to a long point or acuminate at the tip, rounded or narrowed 

 at the base, smooth above, and smooth beneath or hairy on the 

 midrib and veins. 



The flowers are borne terminally and in the axils of leaves in
