Altaian ChamBerhodos. Fl. June, July. PI. prostrate. 



Cult. The species of Chamcerhodos are very difficult to pre- 

 serve through the winter, as they are very liable to be carried 

 off by the damp. They should be grown in pots in a mixture 

 of sand, peat, and loam, and should be placed on a dry shelf 

 in a cold frame in winter, at which time they should be but spa- 

 ringly watered, if at all. They are only to be increased by seed. 



XVIII. AGRIMO'NIA (a corruption of Argemone, a name 

 given by the Greeks to a plant which was supposed to cure cata- 

 ract of the eye, from apyoe, argos, white, the cataract of the 

 eye being white). Tourn. inst. t. 155. Nestl. pot. 16. D. C. 

 prod. 2 p. 587. 



LIN. SYST. Dodecdndria, Digijnia. Calyx tubular, foveolate on 

 the sides, with 5 small acute marginal segments (f. 73. (/.), the 

 tube subsequently hardened, and closed over the seeds, furnished 

 on the outside by a circle of hooked bristles, forming an involucre. 

 Petals 5 (f. 73. 6.). Stamens 7-20, from the rim of the calyx 

 along with the petals. Carpels 2, in the bottom of the calyx. 

 Styles 2, lateral (f. 73. c.). Seeds pendulous. Astringent aro- 

 matic herbs, with interruptedly pinnate leaves, each accompanied 

 by a pair of stipulas united to the petioles. Flowers small, 

 numerous, spiked, yellow. Bracteas trifid (f. 73. a.). 



1 A. EUPATORIA (Lin. spec. FIG. 73. 



643.) hairy or smoothish ; leaves 

 interruptedly pinnate ; leaflets el- 

 liptic-oblong, coarsely serrated, 

 odd one stalked ; petals twice the 

 length of the calyx ; fruit distant ; 

 tube of calyx campanulate, en- 

 circled by a whorl of hooked 

 prickles above ; spikes of flowers 

 elongated. If. . H. Native of Eu- 

 rope, in bushy places by road 

 sides, and about the borders of 

 fields ; plentiful in some parts of 

 Britain. Smith, engl. bot. 1335.

 med. bot. suppl. 258. Fl. dan. t. 

 588. The herb is slightly bitter, 

 aromatic, astringent, evincing a 



tonic property, for which it has always been noted, and which 

 has procured it a place in several British herb teas. In decoc- 

 tion it was formerly used as an astringent for a gargle, and in 

 diarrhoea and leucorrhcea. Kalm informs us, that the Canadians 

 use the infusion of the root with great success in burning fevers, 

 and Dr. Hill says it is an effectual cure for jaundice, sweetened 



with honey, in the quantity of half a pint three times a day. 

 The plant will dye wool of a nankeen colour. It is also recom- 

 mended for dressing leather.
