XLIJ. COMPOsriVE. 



Peduncles much longer than the 

 heads, usually by threes at the 

 tops of the branches. Petioles 

 reddish next the branches. Heads 

 of flowers globular, size of a mar- 

 ble. Stipules deciduous. 



Cephalanthus occidentals. 



Mill.) A bushy shrub. Canada to Florida, in marsh} places. Height 

 3ft. to 6ft. Introduced in 1735. Flowers yellowish white ; July and 

 August. Fruit brownish ; ripe in October. 



Variety. 



& C. o. 2brachypodus Dec. Prod. iv. p. 539. Leaves elliptic- oblong, 

 3 in a whorl, on short petioles. Petioles 3 4* lines long. There are 

 varieties of this, with either glabrous or downy branches. North of 

 Mexico, near Rio de la Trinidad and Bejar. 



It will grow in common garden soil, but -prefers peat kept moist ; and is 

 propagated chiefly by seeds, but will also grow by cuttings and layers. It is 

 an interesting shrub, from its curious round heads of flowers, and from the 

 lateness of the season at which these appear. 



ORDER XLII. COMPO'SIT^. 



ORD. CHAR. Calyx limb membranous or wanting ; or divided into bristles, 

 paleae, or hairs. Corolla 5-toothed or 5-lobed, tubular, ligulate, or bilabiate 

 on the top of the ovarium. Anthers combined, rarely free. Ovarium 1- 

 celled, 1 -seeded. Style 1. Stigmas 2. Fruit an achenium, crowned by 

 the limb of the calyx. Albumen none. Characterised by the cohesion of 

 the anthers, and the arrangement of the flowers in involucrated heads on 

 a common receptacle. (r. Don.) 



Leaves simple, or compound, stipulate or exstipulate, deciduous or ever 

 green. Flowers grouped in heads ; those in each head so disposed, and so 

 environed by an involucre composed of bracteas that corresponds to a 

 calyx, as to seem to constitute but one flower. 



The genera that include hardy ligneous species are mostly natives of Eu- 

 rope and North America : they are all of the easiest propagation and culture 

 in any common garden soil, and are thus contradistinguished :
