valis, V. cordifolia, and V. riparia are the most hard}'. In the 

 Ampelopsis section we have A. qxiinquefolia and its varieties, one 

 of which has sucking tendrils like A. Veitchii., and has been 

 called Engelifnanni \>y some nurserymen. A. heterophylla and its 

 varieties, aconitifolia and serjanke folia, have blue berries. 



uSsculus macrostachya is a fine late flowering shrub with spikes 

 of white flowers, excellent in large clumps on a lawn. Xanthoce- 

 ras sorbifolia, a near relation of the above, from China, is very 

 curious in bloom, but is short lived. 



Staphylea trifolia, our native bladder-nut, is interesting in fruit.- 



All the species of Khus, are fine for large clumps or embank- 

 ments, and when cut within an inch or two of the ground every 

 year make a very tropical appearance. The species typhina 

 (Stag-horn) and glabra, of which the laciniata is a variety, have 

 fine fern-like foliage. R. copallina is one of the finest for autumn 

 coloring. R. venenata and R. Toxicodendron are well known as 

 the poison ivy and poison sumach or dogwood. Rhus aromatica 

 is one of the finest coverings for banks ; when once established it 

 will grow in the poorest of soils. R. Cotinus, the smoke-tree, is a 

 well known shrub, with mist-like flowers. R. semialata Osbeckii 

 is a fine large-growing shrub or small tree from China, with large 

 heads of white flowers in late summer. 



Of Cytisus, we have cap>itatus with round heads of yellow 

 bloom, and C. nigricans with long loose spikes of light lemon-col- 

 ored blossoms, which appear about the first of July. C elongatus 

 bijiorus has round heads of flowers during the early summer. These 

 species are low growing shrubs, seldom exceeding a foot in height. 



Of the Amorpha, we have fruticosa and its many varieties, alii 

 of which are coarse growing shrubs with bluish purple flowers, 

 excepting A. canescens, the lead plant, which seldom exceeds two 

 feet in height, with spikes of purplish blue flowers and dusty foliage. 



The Wistarias are all fine climbing plants, well adapted to all" 

 purposes for which climbers are used. Of these we have Sinensis 

 and Sinensis alba,flore-pleno, W. bracJiybotrys, and W. midtijuga^ 



In Robinias we have R. viscosa, the clammy locust, with pinkish 

 white flowers in June, and Robinia hispida, the rose acacia, with 

 large clusters of pink blossoms which bloom at intervals all 

 summer. There are several varieties of this old-fashioned plants 

 the difference being chiefly in the size of the flowers. 



The species of Colutea, or Bladder-sennas, are very ornamental and 

 if well pruned will continue in bloom most of the season ; the seed
