Grindelia

Guatteria 



GRINDELIA. 



Hardy or half-hardy plants (ord. Composite) 

 chiefly from North America. The evergreen 

 species are propagated in spring by cuttings of 

 half-ripe growth inserted in sand under a bell- 

 glass ; the herbaceous species by division or 

 cuttings. A warm position, and ordinary garden 

 soil, suffice, but the genus is not showy enough 

 to merit extended cultivation. 



Principal Species : 

 angustifolia, H', Aug., grandiflora (AW squar- 



yel. (sijn. Duvalii). rosa). 



glutinosa, 2', Aug., ev., inuloides, 2', Aug., ev., 



yel. (syn. Dom'a gluti- yel. (si/tt. spathulata).

(yn. Donia squarrosa). 



Other Species :

 GRISELINIA. 



The few members of this genus (ord. Cornacese) 

 are Lanrel-like shrubs or small trees, hardy in 

 southern and sheltered parts of the kingdom, but 

 requiring greenhouse protection in other localities. 

 Propagation, by cuttings of firm growth, or by 

 layering. Light, but deep, rich soil is essential. 



Principal Species : 

 littondis, 25', spr., ev., lucida, 10', spr., ev., grn. 



grii. macrophylla, large Ivs. 



GRISLEA. 



Evergreen, shrubby stove plants (ord. Lythra- 

 riea;). Propagation, by cuttings of firm growth in 

 spring, in bottom heat. Soil, fibrous loam and peat, 

 with sand. 



Principal Species : 



secunda, 4', sum., pk., sc. tomentosa (now Wood- 

 fordia floribunda). 



GRONOVIA. 



Interesting annuals, raised from seed sown in 

 heat, and grown in a stove or warm greenhouse. 

 Strings, wires, or sticks must be provided for the 

 plants to climb up. This genus (ord. Loasea?) is 

 remarkable for its stinging hairs. 



Principal Species : 



scandens, (!', sum., yel. 



GROTTO. 



Sometimes an unattractive jumble of plants, 

 stones, shells, and soil is called a grotto, but this is 

 a misnomer. A grotto should be a cool, shady 

 spot, where rockwork and old tree stumps and 

 roots are used with sufficient soil to make an 

 undulating and artistic garden, in which Ferns 

 and many shade-loving plants are grown. Water, 

 too, should form part of the picture, indeed, 

 heavily shaded dells by the brook side, river 

 backwater, or lake form ideal spots for the 

 formation of grottoes. 



GRUBS. 



By this collective title nearly all caterpillars and 

 pupa; are popularly referred to, but many also 



Ground Cherry (xee Ceram* Cltauitrlnixus). 

 Ground lay (see, Nepeta Gleclioma). 

 Ground Laurel (see Epigrca repens). 

 Ground ffut (see Arachisf). 

 Groundsel (see ttcnec'to rnh/nris). 

 Groundsel Tree (see liaccharis halimifoUa). 



include slugs and shell-less snails in the same 

 term. The small Iarva3 of such garden pests as 

 the Cabbage Fly, Carrot Fly, Celirv Fly, Celery 

 Stem Fly, Codlin Moth, Currant Sphinx Moth, 

 Gooseberry Sawfly, Onion Fly, Narcissus Fly, 

 Raspberry Leaf-miner, Rose Beetle, Slug Worm, 

 Turnip Flea Beetle, Turnip Leaf-miner, etc., are, 

 however, those generally referred to by gardeners 

 as grubs. Methods for combating these enemies 

 will be found under the various crops. 



GUAIACUM. 



West Indian trees (ord. Zygophyllere), best 

 known for its heavy wood and the medicinal 

 properties of the bark of officinale, a species 

 known as the Lignum Vitre tree. Evergreen stove 

 trees, that will grow in rich, light loam, and are 

 increased by cuttings in spring, in bottom heat. 



Principal Species : 



arboreum, 30', sum., bl. verticale, 12', sum., bl. 

 officinale, 45', sum., bl. 



GUANO. 



Briefly stated, guano is the accumulated deposit 

 of sea birds' excrement, found upon certain islands 

 iind coasts where there is a small rainfall. The 

 value of guano lies chiefly in its nitrogen, which is 

 mostly in such combinations as hydro-chlorate, 

 oxalate, phosphate, urate, etc., of ammonia. But 

 the supply of guano has decreased rapidly, and its 

 quality has fallen also. With the decrease of the 

 percentage of ammonia there has been an increase 

 of phosphates. In short, as a nitrogenous manure 

 natural guano is passing out of the market, and its 

 place is being taken by fish guano and other 

 artificial productions. In a dry state guano is an 

 excellent top-dressing for almost all kitchen garden 

 crops, but, being highly stimulative, should not be 

 applied to crops during autumn or winter. It is 

 better to give two applications, with an interval 

 and change of manure between, than to give a 

 large dose at one application. According to the 

 quality of the guano the rate of application should 

 be from 1 oz. to 3 oz. per square yard. Plants in 

 pots should not be given guano until the pots are 

 fairly well filled with roots ; it may then be given 

 to Begonias. Chrysanthemums, Pelargoniums, 

 Balsams, etc., in liquid form, not more often than 

 once a week, at the rate of J oz. dissolved in 1 

 gallon of water. Liquid cow manure forms an 

 excellent change of food for guano-fed crops. 



GUAREA. 



Evergreen stove trees (ord. Meliacea?), requiring 

 similar cultural treatment to that outlined for 

 Guaiacum. The several species grow about 25' 

 high, and bear white flowers. The chief are 

 coffeaifolia and ramiflora. 



GUATTERIA. 



Stove trees and shrubs (ord. Anonaceas), with 

 evergreen foliage. All can be increased in spring 

 by cuttings placed in sandy soil in bottom heat. 

 Cerasoides, Korintii, and suberosa are now referred 

 to the genus Polyalthia. 



Principal Species : 



rufa, 6', br. virgata, 30', wh., fragrant. 



Oryllta (see Crickets), 

 (!ri/ltilpa, (see Mole Crickets'), 

 (inaltlicria (sec Gaultheria).
