tings, and will grow in any light sandy soil ; at- 

 taining the height of -> ft. or 3 ft. in three or four 

 \ears. It was cultivated by Parkinson in 1640. 



App. i. Half-hardy Species of 



StccJiclfnz. L. There are two green-house species, S. arbon'sccns 

 and S. Chama-peucc, both considered pretty plants ; the first grow, 

 ing.to the height of 6 ft., and the other to that of 2 ft. ; which, being 

 natives of Candia, and thriving quite well in a frame, are doubtless 

 lit lor a conservative wall or conservative rockwork. 



Itctmirk. We may observe here that such plants as the different 

 species of SteheUna, hardy and half-hardy, are rarely, if ever, to 

 be found in the public nurseries. Their culture is in general confined to the collections of curious 

 individuals; or some of our public botanic gardens. Hence the great value of such gardens, in a 

 scientific point of view ; since, by means of them, many plants are preserved alive in the country. 

 that would otherwise be known to botanists only through books or herbariums ; and which would 

 never be seen by the general observer at all. Botanic gardens, therefore, exist, more or less, in 

 every civilised country, as a part of the national institutions ; and in some countries, as in France, 

 they are very properly supported at the expense of the local, or general, government. 



GENUS II. 



.BA'CCHARIS R. Br. THE BACCHARIS, or PLOUGHMAN'S SPIKENARD. 

 Lin. Syst. Syngenesia Superflua. 



Identification. Less. Syn. Gen. Compos., p. 204. ; Ait. Hort. Kew., ed. 2. vol. 5. p. 25. 



Synonymes. Bacchante, Ft: ; Baccharis, Ger. 



Derivation. From Bacchus, wine ; because of the vinous odour of its root. Pliny says the root 

 smells of cinnamon : but, as the ancients sometimes boiled down their wines, and mixed them with 

 spices, these wines may have had an odour similar to that of the root of the baccharis.

\ngravings. 



Spec. Char., $c. Leaves obovate, crenately notched on 

 the terminal portion. (Willd. Sp.Pl. t \u. p. 1915.) 

 Flowers white, with a tint of purple, and re- 

 sembling those of the groundsel, but larger. A 

 native of North America, on the sea coast, from 

 Maryland to Florida. It has been in cultivation 

 in British gardens since 1683 ; it grows to the 

 height of 8ft. or 10ft., and flowers from Septem- 

 ber to November. It is chiefly remarkable for the 

 glaucous hue of its leaves, in consequence of the 

 whole plant being covered with a whitish powder. 

 Its general appearance accords with that of the genus 

 ^'triplex, and the shrubs of both families are, accord- 

 ingly, well calculated for being grouped together. 

 -Baccharis Aalimifofia will grow in any common soil 

 which is tolerably dry, attaining the height of 6 ft. or 

 8ft., in 3 or 4- years, and forming a large, loose- 

 headed, robust-looking bush, of from 10 ft. to 12 ft. 

 in height, and 12 ft. or 15 ft. in diameter, in 10 years. 

 It is readily propagated by cuttings. Price of plants,
