less united; leaves opposite; stipules none. A family with many showy flowers, 
and having some astringent and purgative properties among its representatives. 
Diervilla. BusH-HONEysUCKLE. The taper-pointed ovary crowned by 
slender calyx teeth; fruit a many-seeded pod; flower regular, or nearly so, 
and funnel-form. Low shrubs, usually free bloomers. Much confusion exists 
_as to what forms now in cultivation can be regarded as genuine natural species 
and what mere garden varieties. 
Diervilla Japonica. De Candolle. A low, vigorous shrub, native of China 
and Japan. It produces a profusion of rose colored flowers an inch or more 
long. Commonly known in gardens as Weige/a rosea. In the opinion of 
Josiah Hoopes, all the following may be regarded as forms of this species: 
D. arborea grandiflora; D. amabilis; D. Desboisi; D. Granewegeni; D. 
hortensis; D. tsolene; D. purpurata; D. Steltzneri; with a host of less 
striking ones. 

Diervilla multiflora, ? Hoopes regards this, with its small, deep- 
crimson flowers, as a quite distinct species. 
* Diervilla sessilifolia, Buck/cy. From the Southern Alleghanies. Has 
sessile, ovate-lanceolate leaves and small yellow flowers. 
* Diervilla trifida, 2/énch. Is a native of this region. Leaves oblong, 
taper-pointed, with petioles; flowers light yellow, 3¢ of an inch long. 
Leycesteria is related to the genus Lonicera, but has § cells and many 
seeds in its mature fruit. The single species we have is 
Leycesteria formosa, Wa//ich. A branching shrub, with hollow branch- 
lets, and broadly lance-shaped, sharp-pointed leaves on hairy foot-stalks ; 
flowers white and purple tinged, disposed in clusters at the ends of the branches; 
berry intensely purple. From the Himalaya and Khasia mountain regions. 
Lonicera. HONEYSUCKLES. Tubular flower, irregular, more or less bulging 
on one side; ovary 2- to 3-celled and few-seeded. 
Lonicera alpigena, Zimn@eus. Erect; leaves ovate or broadly lance- 
shaped, smooth or nearly so; berries united in pairs, red. From the Alps of 
Europe. Lonicera Sibirica of the gardens is probably but a variety of the 
above. 
Lonicera brachypoda, De Candolle. NEW JAPAN EVERGREEN HONEY- 
SUCKLE. Stem twining; young branches covered with spreading hairs; flowers 
fragrant, white and yellow. From Japan. Hoopes considers Lonicera Halli- 
ana as a form of the above. 
* Lonicera Caprifolium, Zimneus. EUROPEAN HONEYSUCKLE. Stems 
twining ; flowers purple and white, or yellowish inside, fragrant ; leaves smooth. 
** Flowers in early summer.” 
* Lonicera ciliata, Muhlenberg. EARLY FLY HONEYSUCKLE. An erect 
native shrub, much branched; thin leaves hairy on the under surface; yellow 
flower, 3¢ of an inch long, “base of flower very unequal-sided ;” berries not 
united in pairs.
