OF THE HARDY OR HALF-HARDY LIGNEOUS PLANTS OF THE ORDER 

 E SC A L L O N/,i' CE^. 



There is only one perfectly hardy genus belonging to this order ; viz. /'tea ; 

 and the principal genus, which is half-hardy, is Escallon/V?. Both are highly 

 ornamental shrubs; the former indigenous to North America, and the latter 

 to Chili, and other parts of South America. 



Genus I. 



/'TEA L. The Itea. Lin. Syst. Pentandria Monogynia. 



Identification. Lin. Gen., i'75. ; Dec. Prod., 4. p. 6. ; Don's Mill., 3. p. .'396. 

 Synonymes. Cedrfela Lour. ; Diconangin Slicht. 



Derivation. Itea is the Greek name of the willow, which is given to this genus on account of the 

 quick growth of the /'tea virginica. 



Gen. Char. Calyx bell-shaped, with 5 teeth, persistent. Petals 5, their 

 aestivation valvate. Stamens 5, shorter than the petals. Both petals and 

 stamens inserted upon the tube of the calyx. Teeth of calyx, petals, and 

 stamens, alternate with one another. Ovary not connate with the calvx. 

 Sfy/e, at first, seemingly one ; afterwards it parts into two portions : hence, 

 there are rather 2 styles connate. Stig))ias capitate, mostly divided by a 

 furrow. Carpels two, connate into a capsule of 2 cells, that has 2 furrows, 

 and parts from bottom to top. Seeds in two rows along the introflexed 

 margins of the carpels. {Dec. Prod.,\\. p. 6.) — A shrub, with simple alter- 

 nate leaves, and flowers in racemes.

 Racemes simple, terminal. (Du?i's AIilL,in. p. 196.) 

 A deciduou.s shrub, growing to the height of 6 ft. or 

 7 ft. A native of North America, from Pennsyl- 

 vania to Carolina; introduced in 1744; and pro- 

 ducing its white flowers, in terminal racemes, from 

 June to August. It may be propagated by cuttings, 

 but more readily by layers, suckers, or seeds; and 

 it thrives best in a sandy or peaty soil, kept moist. 

 The plant, to be kept in vigour, should have the 

 old wood frequently cut down to the ground. When 

 grown in a situation that is rather moist, its flowers 

 make a fine appearance, at a season when there are few other shrubs in 

 blossom. It is most frequently propagated by seeds, which are annually 

 received from America. The price of plants, in the London nurseries, is
