Urticace^e, or Nettle-worts. An order of 

 herbs, shrubs, and trees. Nettles are well 

 known as possessing excessive causticity in 

 their juice ; the stinging species of this coun- 

 try are, however, not to be compared with 

 <jome of the East Indian species, as V. crenu- 

 lata, stimulans, and urentissima (or devil's-leaf, 

 as.it is called), when the pain occasioned is so 

 acute and violent as to produce the most 

 dangerous effects.

 these plants best, and they are readily increased 

 by division at the root. See Disporum.

VACCAEIA. See Saponaria. 

 VACCfNiUM, Linn. An ancient Latin name, 

 whether of a berry or a flower is not satisfac- 

 torily known. Linn. 8, Or. 1, Nat. Or. Vac- 

 cinidcece. All the species of this genus are well 

 worth cultivating, some of them for the sake 

 of their fruit, some for curiosity, and others 

 for ornament. The different kinds of Whortle- 

 berry and Bilberry succeed best in peat soil, or 

 very sandy loam. Some of them grow best in 

 moist situations, and others in dry. Those 

 ' requiring the heat of the stove must receive 

 the same treatment as the generality of stove 

 plants ; and are readily increased by cuttings, 

 planted in sand, under a glass, in heat ; they 

 may, also, like the hardy species, be raised 

 from root-suckers, creeping roots, trailing root- 



ing stems, or from seeds treated as follows : — 

 In autumn, as soon as the seeds are ripe, they 

 should be sown in shallow pans, filled with 

 very sandy peat soil, and covered slightly 

 over ; when about an inch high, they must be 

 pricked out thinly into other pans, filled with 

 the same kind of soil. After being well rooted 

 in these pans, they must be planted out in 

 spring in proper places, taking care to keep a 

 ball of earth about the roots. If finally planted 

 out in autumn, the worms are apt to throw 

 them out of the ground during winter. Syno-
