Staghorn Sumach (E. UjjjMna) is especially note- 

 worthy on account of its elegant, compound leaves, which 

 assume colors of great brilliancy in autumn, at which 

 time it bears its bunches of crimson berries, C. 



The Cut-leaved Sumach {R. glabra, var. laciniata) 

 is a variety of our most common native species, with re- 

 markably handsome, fern-like leaves, which are dark- 

 green above, and glaucous below.

The Lilac, represented by a large number of species, 

 and innumerable varieties, is one of our most valuable 

 ornamental shrubs. Of the easiest culture in any or- 

 dinarily good soil, with attractive foliage and very fragrant 

 flowers, it is rarely the case in adorning grounds, what-

 head. The well-known 



Common Lilac {S. vulgaris), with purple and white 

 flowers, still ranks high in value. From this have sprung 

 many varieties, some of which are improvements on the 

 species. Some of these have larger flowers than the 

 parent, or differently colored ; others vary in their 

 habit of growth, there being both dwarf and stronger 

 growing sorts, and there is one variety called Golden- 

 leaved Lilac (var. variegata), with large, yellowish-green 

 foliage, which is valuable for creating contrasts of color. 

 The Asiatic species possess great value, being, as a rule, 

 more graceful and delicate in form, and with smaller 

 leaves than those of the Common Lilac.

 of somewhat loosely arranged, dark lilac flowers. This
