SPIR.EA 535 



S. EXPANSA, K. Kock. 

 (S. fastigiata, C. K. Schneider ( Wallicli).*) 



A shrub up to 6 ft. high, with slender, round, downy stems, erect and not 

 much branched; buds hairy. Leaves lanceolate to ovate, up to 4 ins. long 

 by i ins. wide; coarsely and sharply toothed (both simply and doubly) 

 except at the base, dark green above, hairy on the veins and rather glaucous 

 beneath; stalks to \ in. long. Flowers white with a flush of red, borne in 

 flat compound corymbs from 2 to 8 ins. across ; calyx and flower-stalks 

 downy. It blossoms on the shoots of the year in July and August. 



Native of the Himalaya; much confused with S. bella, but differing in 

 having round stems, more hairy leaf-buds, and larger, flatter corymbs. 



S. GEMMATA, ZabeL 



A shrub 4 to 8 ft. high, with slender, arching, more or less angular stems, 

 quite smooth ; buds slender, pointed, longer than the leaf-stalk. Leaves 

 narrowly oblong, from \ to i in. long, \ to \ in. wide; often entire with a 

 short abrupt tip, but sometimes blunt and with about three teeth at the end; 

 green and quite smooth on both surfaces. Flowers white, small, produced 

 during May in corymbs about i in. across; flower-stalk smooth, slender. 



Native of Mongolia, and usually found in gardens as " S. mongolica." A 

 pretty, white-flowered shrub distinct amongst others of its group by reason 

 of its long, slender leaf-buds. 



S. HENRYI, Hemsley. 



(Bot. Mag., t 8270.) 



A shrub of lax, spreading habit, 6 to 9 ft. high, more in diameter; branches 

 reddish brown, slightly hairy when young. Leaves of the barren shoots 

 2 2 to 3i ms - l n g> I to J ins. wide; narrowly oblong or oblanceolate, coarsely 

 toothed near the apex; those of the flowering twigs much smaller, f to i^ ins. 

 long, oblong or obovate, more shallowly toothed at the apex than the others, 

 sometimes entire; all covered more or less with loose, greyish down beneath. 

 Flowers white, \ in. across, produced in June on rounded corymbs, 2 ins. 

 across, which terminate short, leafy twigs; flower-stalk and ovary downy. 



Native of Central China ; named in honour of Prof. A. Henry, who first 

 discovered it near Ichang in 1885; introduced for Messrs Veitch by Wilson 

 in 1900. It is a fine shrub, and stands in the front rank of Spiraeas, but on 

 account of its wide-spreading habit needs plenty of space for lateral develop- 

 ment; it is better as an isolated plant than grouped in a shrubbery. Shoots 

 6 ft. or more long are made in a season. 



S. WlLSONl, Duthie (Bot. Mag., t. 8399), is closely allied to, perhaps only 

 a variety of S. Henryi. It is distinguished among other points by its smooth 

 ovary, and smooth or slightly silky flower-stalks. Leaves of flowering shoots 

 entire, downy above, duller green. 



S. HYPERICIFOLIA, Linnceus. 



A bushy shrub, 5 or 6 ft. high, with graceful, arching, twiggy branches, 

 which, when young, are brown and usually covered with fine down, becoming 

 grey with age. Leaves obovate, with a tapering base, and about three teeth 

 at the apex, or none at all; to \\ ins. long, to \ in. wide; of a greyish 

 green, slightly downy beneath, three or five nerves running lengthwise;
