j ii. Chamtedryon Ser. 



Derivation. From Chamadrys, the name of the germander; from a similarity in the form of the 

 leaves, 



&c#. C/w. Ovaries distinct. Torus with its base connate with the tube of 



the calyx, but with its tip separate. Carpels not inflated. Flowers each 



upon a distinct pedicel, and disposed in umbels or corymbs. Leaves entire, 



or toothed, without stipules. (Dec. Prod., ii. p. 542.)

Spec. C/iar., $c. Leaves ovate, cut at the tip in a serrated manner, glabrous. 

 Flowers upon long slender pedicels, in hemispherical corymbs. Sepals veiny, 

 reflexed. (Dec. Prod., ii. p. 542.) 

 Varieties. Seringe enumerates the first four of the following forms of this 

 species ; to which, we think, might be added S. zdmifolia, S. flexuosa, 

 S. rrataegifolia, S. ^etulaefolia, and, perhaps, some others. 



* S. c. 1 vulgaris Camb. Monog. — Leaves with the disks broad and 



glabrous ; the petioles ciliated. 

 Sfc S. c. 2 media Ph. Fl. Amer. Sept., i. p. 342., Camb. Monog. — Leaves 

 smaller, slightly villose upon both surfaces. Flowers smaller. Wild 

 in Canada, and upon the rocks of Dahuria. 

 s S. c. 3 oblongifolia Camb. Monog. ; S. oblongifolia Waldst. et Kit. PL 

 Hung., iii. p. 261. t. 235., and in Hort. Brit. — Leaves narrower, and 

 less serrated. 

 ^ S. c. 4 subracemosa Ser. — Flowers distantly disposed along a length- 

 ened rachis. 

 sis S. c. 5 incisa Hort. ( ? S. incisa llninb.) has been raised from seeds 

 received from Germany through Mr. Hunneman ; and it appears to 

 be only a variety of this species. 

 Description, efc. A shrub, varying in height from 429 



2 ft. to 6 ft., or more ; a native of Siberia, Kamt- 

 schatka, Dahuria, the north-west coast of America, 

 and also of China and Japan. It is common through- 

 out the whole of Siberia, Dahuria, and Kamtschatka; 

 and, in the latter country, the leaves are used as a 

 substitute for tea ; and the shoots, when straight, are 

 bored for tobacco-pipes. It was introduced into 

 England in 1789, under different names; and its 

 numerous varieties have, we believe, given rise 

 to several supposed species. In its wild state, it 

 varies exceedingly in the magnitude of the entire 

 plant, in the largeness or smallness of its leaves, and 

 in their being more or less cut or serrated, and more ^ 

 or less smooth, or pubescent. In British gardens, it is :- 

 a very ornamental hardy shrub, producing its corymbs U« 

 of white flowers, which are tolerably large, in June 

 and July ; and they are succeeded by capsules, the 

 seeds enclosed in which are grey and small, resembling sawdust. In Martyn's 

 Miller it is stated, that this shrub makes beautiful garden hedges, being 

 entirely covered with its white flowers in June. Though the seeds ripen in 

 England, plants can seldom be raised from them; and, as this species does 

 not produce suckers freely, it is generally raised by layers or cuttings.
