and of the easiest culture. They all succeed in 
any common garden soil; and are increased by 
cuttings, divisions, and seeds. The effects of the 
venomous sting of the common Nettle are well 
known, but are, however, not to be compared with 
those of some of the Indian species, grown in the 
gardens of this country ; yet ^ the known species 
are far surpassed for virulence by one, which in 
Timor is called daoun setan, or devil’s leaf, the 
effects of which are said by the natives in many 
cases to cause death.

V ACCINICM. Linn. An ancient Latin name, 
wlrelher of a berry or a flower, is not satisfac- 
torily known. Linn. 8, Or. 1, Nat. Or. Vaccinaceas. 
All the species of this genus are well worth culti- 
vating, 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 generzility 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, 
[ 325 ] 
creeping roots, trailing rooting 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. Synonymes : 1 . V. myrtilloides. 2.
