S. TOMENTOSA. Tomentose Spiraea. North America, 

 1736. This species grows 2 feet or 3 feet high, has rusty 

 tomentose shoots and leaves, and large, dense, compound 

 spikes of showy red flowers. Flowering in summer. 



S. TRILOBATA (syn S. triloba). Three-lobed Spiraea. 

 Altaian Alps, 1801. This is a distinct species with hori- 

 zontally arranged branches, small, roundish, three-lobed 

 leaves, and white flowers arranged in umbel-like corymbs. 

 It flowers in May, and is quite hardy. 



S. UMBROSA (Shady Spiraea) and S. EXPANSA (Expanded- 

 flowered Spiraea), the former from Northern India and the 

 latter from Nepaul, are well suited for planting in some- 

 what shady situations, and are very ornamental species. 

 The first-mentioned grows about a foot high, with rather 

 large leaves, and cymes of white flowers on long, slender 

 footstalks ; while S. expansa has pink flowers, and lance- 

 olate, coarsely serrated leaves. 



There are other valuable-flowering kinds, such as 

 S. capitata, with ovate leaves and white flowers ; S. 

 pikowiensis, a rare species with white flowers; S. cunei- 

 folia, with wedge-shaped leaves and panicles of pretty 

 white flowers; and S.vacciniaefolia, a dwarf-growing species, 

 with small ovate, serrulated leaves and showy, pure-white 

 flowers. S. betulifolia and S. chamaedrifolia flexuosa are 

 worthy forms of free growth and bearing white flowers. 

 The Spiraeas succeed in almost any garden soil, probably 

 preferring a rich, ,sandy loam.

 known but beautiful deciduous shrub of medium height, 

 with ovate-lanceolate leaves 4 inches to 6 inches long, and
