perennials. Offsets. Sandy peat. 



GEITONOPLESIUM. Three spe- 

 cies. Green-house herbaceous peren- 

 nials. G. cymodum, is an evergreen 

 twiner. Cuttings. Peat and loam, or 

 sandy peat. 



GELA. Two species. Green-house 

 evergreens. Cuttings. Sandy peat 



GELASINE azurea. 

 bulbous perennial. 



GEM. See Bud. 



GENISTA. Forty-nine species and 

 a few varieties. Chiefly hardy ever- 

 green shrubs. A few deciduous or ever- 

 green trailers and shrubs. For the 

 green-house or half hardy kinds, cut- 

 tings, loam, peat, and sand. The 

 hardy kinds are increased by layers or 

 seeds. 



GENTIAN A. Fifty-eight species 

 and some varieties. Hardy plants 



G. piniaria attacks the pine and fir 

 tribe. 



GEONOMA. Six species. Palms. 

 Seed. Rich sandy loam, and a strong 

 heat. 



GERANIUM. Fifty-one species and 

 some varieties. Chiefly hardy herba- 

 ceous perennials. The green-house 

 Green-house and frame kinds increase from cuttings 

 or seeds, and grow well in a mixture of 

 loam and peat, and vegetable soil. The 

 hardy species and the annuals increase 

 from seeds, and require only common 

 soil. See Pelargonium. 



GERARDIA. Seven species. Hardy 

 annuals, biennials, and herbaceous pe- 

 rennials. Seed or cuttings. Peatv soil. 



GERBERA crenata. Green-house 

 biennial. Seeds. Sandy loam and peat. 



GERMINATION is the sprouting, or 

 first step in vegetation of a seed. To 



The herbaceous kinds for the most part > enable it to germinate, it must have a per 



grow well in a rich peaty soil, and 

 may be increased by division- The 

 annuals and biennials by seeds. Com- 

 mon soil. 



GENTIANELLA. Gentiana acaulis. 

 Is a hardy and herbaceous creeper. 

 Sow the seeds of this as soon as they 

 are ripe, (otherwise they soon lose the 

 power of vegetation,) in pans filled with 

 rather heavy peat. Sow on the surface, 

 without any covering except a slight 

 sprinkling of silver sand ; then place 



feclly-developed embryo, and be ripe, or 

 nearly ripe. It must not be too old. 



The following list, furnished by the 

 late Mr. Loudon, shows the greatest 

 age at which some of our common gar- 

 den seeds germinate freely ; and this 

 result of experience is quite concurrent 

 with our knowledge of their chemical 

 constitution : — 



"One year. — Peas, beans, kidney 

 beans, carrot, parsnip, oraches, herb- 

 patience, rhubarb, elm, poplar, and 



the pans either in a cold frame facing | willow. Two years. — Radish, salsafy, 

 the north, and kept close, or on the i scorzonera, purslane, the alliums, car- 

 north side of a wall, where they are i doon, rampion, alisander, love-apple, 

 completely screened from the sun, and capsicum, egg-plant. Three years. — 

 cover them with a hand-glass. i Sea-kale, artichoke, lettuce, marigold, 



Soil. — A light loam suits it best ; ma- rue, rosemary. Four years.-^Brassicas, 



nured annually with leaf mould. If the 

 subsoil is dry, the soil may be advan- 

 tageously more clayey. 



GEOMETRA. The Amphidasis of 

 some entomologists, is a genus of moths; 

 including G. polosaria. Pale Brindled 

 Beauty Moth which appears in March ; 



skirret, spinach, asparagus, endive, 

 mustard, tarragon, borage. Five and 

 six years. — Burnet, sorel, parsley, dill, 

 fennel, chervil, hyssop. Ten years. — 

 Beet, celery, pompion, cucumber, me- 

 lon." 



Mr. Loudon may be safely received 



ego-s deposited in bands round a twig, as good authority on subjects which he 

 as done by the Lacky Moth. Caterpil- ] investigated. If the age at which the 

 jars appear with the opening leaves of | vitality of certain seeds cease in Eng- 



the elm, lime, lilac, and apple tree. 

 They are at first a light green. 



G. defoliaria, Lime Looper, or Mot- 

 tled Umbre Moth, feeds on the leaves 

 of the lime and apple. Moth appears 

 in November. Caterpillar reddish, with 

 a bright yellow stripe on each side. 

 Female moth has no wings, so that a 



and as expressed herein, be correct, it 

 proves a result in that climate different 

 from our own. For instance, peas, 

 beans, carrots, &c., vegetate freely in 

 the United States when two or three 

 years old, sea-kale seldom after the 

 first year, and so of other seeds enume- 

 rated in the list.
