Description, $c. A shrub, a native 426 



of Japan, introduced in 1700, and for 

 a long time treated as a stove, and 

 afterwards as a green-house, plant ; 

 but it has been ultimately found quite 

 hardy. It has soft, and not very per- 

 sistent, wood, clothed with a smooth 

 greenish bark ; twig-like branches ; 

 leaves that are ovate-lanceolate, and 

 serrated with large and unequal teeth, 

 feather-veined, and concave on the 

 upper surface ; stipules that are linear- 

 subulate; and yellow flowers. The 

 single-flowered state of this species 

 has only lately been introduced ; and 

 it flowered, for the first time in England, in the Chelsea Botanic Garden, in 

 April, 1836. The double-flowered variety has become so common as to be 

 found in the gardens even of labourers' cottages. It is a most ornamental 

 and beautiful shrub, from its very numerous, large, golden, sub-globular blos- 

 soms, which begin to appear in February or March, and, in tolerably moist 

 soil, and a warm situation, continue to be produced for several months. It is 

 generally planted against a wall, more especially north of London. It is 

 easily and rapidly propagated by its sprouting suckers. Plants, in the London 

 nurseries, are 50s. per 100; at Bollwyller, it is 10 francs per 100; and at 

 New York, 50 cents each.

L. THE SPIRAEA. Lin. Syst. Icosandria Di-Pentagynia. 



Identification. Lin. Gen., No. 630. ; Gaertn. Fruct., 1. p. 337. t. 69. : Dec. Prod., 2. p. 541. : Don's 

 Mill., 8. p. 517. 



Synonymes. Spirae^a sp. Cambessedes Man. Spir. in Ann. Sci. Nat., 1. p. 227. ; SpirtJe, Fr. ; Spier, 

 staude, Ger. 



Derivation. From speira, a cord, in reference to the supposed flexibility of the branches of some 

 of the species; or, according to some, from speirao, to wreath; in allusion to the fitness of the 

 flowers to be twisted into garlands. Spirteon is Pliny's name for a plant the blossoms of 

 which were used, in his time, for making garlands ; but that plant is thought by some to have been 

 the riburnum Lantana. 



Description, fyc. Low deciduous shrubs, with conspicuous flowers of con- 

 siderable elegance and beauty. They are all readily propagated by suckers, 

 which, in general, they produce in abundance. They will grow in any common 

 soil; and the price of most of the sorts, in the London nurseries, is from 1*. 

 to 1*. 6d. each, or from 50s. to 75*. per hundred ; at Bollwyller, from 50 cents
