GRISLEA (named in honour of Gabriel Grisley, 
author of a work on the Botany of Portugal, who lived in 
the seventeenth century). ORD. Lythrariew. A genus now 
limited to the one species described below, which is a 
very pretty stove evergreen shrub. It thrives in a com- 
post of fibry and sandy peat and loam. Propagated by 
cuttings, obtained in spring from firm young shoots, 
and inserted in sandy soil, under a bell glass, in heat. 
G. secunda (side-flowering). M. pale pink ; stamens long, purple.

stove epiphytal orchids, natives of Brazil. Flowers yellow 
or greenish, tinged and spotted with purple, in short 
racemes; petals broader than the sepals, forming a sort 
of helmet overhanging the lip; lip small, five-lobed at 
the apex. Leaves grass-like, ribbed at the apex. Pseudo-

GRONOVIA (named in honour of Dr. John Frederick 
Gronovius, a learned botanist at Leyden; he was a friend 
of Linnseus, and died in 1763). ORD. Loasew. A scandent 
stove or greenhouse annual herb, somewhat resembling the 
common Bryony. It succeeds in a rich sandy loam. Pro-

large enough, being potted off singly, and trained upon 
sticks.

Grubber (see Fig. 155) is a short implement, made with a 
claw, for removing the roots of Daisies from lawns. It 
is furnished with a handle, and the fiat portion (a) is 
bent to form a leverage when pressed on the ground. 
GRUBS. Apple Grubs may be the larve either of 
a beetle, Anthonomus pomorwm, or of a small moth, 
Carpocapsa pomonana. The beetle belongs to the group 
of Weevils, or long-snouted beetles. It is about iin. 
long, and of a dark colour. In June, the females lay 
their eggs in the flower buds (one egg in each), and 
the larvæ soon emerge and liye in the interior of the 
bud; which remains unopened. The grub is footless, of a 
pale colour, with a dark head. ‘The only remedies are to 
remove and destroy the buds containing the larve and 
pupx, and to shake from the branches and destroy the 
females before they have laid their eggs. See also 
Apple or Codlin Grub.

GUAIACUM (from Guaiac, its South American name). 
ORD: Zygophyllee. A genus containing about eight species 
of lofty stove evergreen trees or shrubs, inhabiting the 
West Indies and sub-tropical North America. Flowers 
blue or purple; peduncles axillary, one-flowered. Leaves 
opposite, abruptly pinnate; leaflets entire. Guaiacums 
require a compost of rich, sandy, fibry loam. Propagated 
from ripened cuttings, obtained in April, and inserted in 
sandy soil, under a hand glass, in heat.

the fragrant resin commonly called gum guaiacum, which, as well 
as the bark and wood, is used medicinally.
