THE DICTIONARY OF GARDENING, 



GRISLEA (named in honour of Gabriel Grisley, 

 author of a work on the Botany of Portugal, who lived in 

 the seventeenth century). OBD. Lythrarieas. 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), fl. pale pink ; stamens long, purple. 



I. on short petioles, puberulous on both surfaces. Branchlets 



glabrous, h. 4ft. to 6ft. Venezuela and New Grenada, 1820. 

 G. tomentosa. See Woodfordla tomentosa. 



GROBYA (named after Lord Grey, of Groby, a 

 munificent patron of horticulture; he died in 1836). 

 OED. Orchidece. A genus containing two species of 

 greenhouse 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-bulbs ovate. For culture, see Stanliopea. 



G. Amnerstlae (Lady Amherst's).* /. ochre-spotted, in pendulous 

 racemes. September. I. linear, acute, striated. Pseudo-bulbs 

 ovate, green, terete, h. 6in. 1829. (B. B. 1740.) 



G. galeata (helmeted). fl. green, purple; petals oblong, 

 obliquely-rhomboid, rounded at top, disposed into a helmet 

 along with the dorsal sepal ; lateral sepals deflexed, connate at 

 base ; lip tripartite ; lateral segments linear, middle one cuneate- 

 truncate, with a toothed disk, warted from shining tubercles. 

 Summer. I like those of G. Amherstias. h. 6in. 1836. 



GRONOVIA (named in honour of Dr. John Frederick 

 Gronovius, a learned botanist at Leyden ; he was a friend 

 of Linnaeus, and died in 1763). ORD. Loasece. A scandent 

 stove or greenhouse annual herb, somewhat resembling the 

 common Bryony. It succeeds in a rich sandy loam. Pro- 

 pagated by seeds, sown on a hotbed ; the seedlings, when 

 large enough, being potted off singly, and trained upon 

 sticks. 



G. scandens (climbing). /. yellow, small; calyx with a five- 

 toothed border, funnel-shaped ; petals five, inserted in the calyx 

 tube. June and July. I. alternate, petiolate, broad-cordate, five- 

 lobed, stringy. Texas to Venezuela, 1731.

 roots or splitting wood, is in a line with the handle ; and 

 the other is placed in a transverse direction for clearing 

 roots of soil (see Fig. 154). What is known as a Daisy 



FIG. 155. DAISY GRUBBER. 



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 flat portion (a) is 

 bent to form a leverage when pressed on the ground. 



GRUBS. Apple Grubs may be the larvae either of 

 a beetle, Anthonomus pomorum, or of a small moth, 

 Carpocapsa pomonana. The beetle belongs to the group 

 of Weevils, or long-snouted beetles. It is about sin. 

 long, and of a dark colour. In June, the females lay 

 their eggs in the flower buds (one egg in each), and 

 the larvae soon emerge and live 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 larvae and 

 pupae, and to shake from the branches and destroy the 

 females before they have laid their eggs. See also 

 Apple or Codliii Grub.

GUAIACUM (from Guaiac, its South American name). 



ORD. Zygopkylleae. 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. 



G. arborea (tree-like). /. blue, disposed in loose racemes. July. 



I. with seven to fourteen pairs of oval-oblong, blunt leaflets, which 



are unequal at the base, and are usually alternate. A. 40ft. Car- 



thagena, 1816. 



G. offlcinale (officinal).* Lignum Vifce. /. blue ; peduncles twin. 

 July. I. with two pairs of obovate or oval blunt leaflets. Bark 

 smooth, variegated with green and white ; wood with a peculiar 

 acid aromatic scent, h. 30ft. Jamaica, 1694. (B. M. PI. 41 ; 

 B. R. 1839, 9.) This species yields the Lignum Vita;, a greenish- 

 brown, hard, heavy wood, extensively used by turners ; and also 

 the fragrant resin commonly called gum suaiacum, which, as well 

 as the bark and wood, is used medicinally.

 stove evergreen trees or shrubs, natives of tropical 

 America, but rarely seen in cultivation. Flowers white 

 or reddish, in axillary panicles, racemes, or spikes. Leaves 

 pinnate; leaflets opposite or alternate. For culture, see 

 Guaiacum.

 short, rising from the sides of the branches. /., leaflets ovate- 

 lanceolate, h. 20ft. Porto Eico, 1822. Tree.
