GLASTONBURY THORN. CratcE- 

 gus oxyacantha. 



GLAUCIUM. Six species, one va- 

 riety. Hardy annuals and biennials. 

 Seeds. Common soil. 



GLAUX maritima. Hardy herba- 

 ceous trailer. Seeds. Open sandy loam. 



GLAZING. See Stove. 



GLEDITSCHIA. Ten species, be- 

 sides varieties. Hardy deciduous trees. 

 Seeds. Any soil suits them. 



GLEICHENIA. Five species. Stove 

 herbaceous perennials. Division. Peat 

 and loam. 



GLOBE-AMARANTH. Gomphrena. 



GLOBE-FLOWER. Trollius. 



GLOBE-THISTLE. Echinops. 



GLOBULARIA. Nine species. Hardy 

 or green-house herbaceous perennials. 

 Cuttings or seed. The green-house spe- 

 cies thrive in loam and peat; the hardy 

 kinds in sandy light soil. 



GLOBULEA. Sixteen species, be- 

 sides varieties. Green-house herbaceous 

 perennials. Cuttings. Sandy loam and 

 peat, with brick rubbish. 



GLORIOSA. Four species. Chiefly 

 stove bulbous perennials. Division ; also 

 seeds sown as soon as gathered. Turfy 

 loam, white sand, and peat. 



G. superba. — Mr. W. Scott, of Bury 

 Hill, gives these particulars as to its 



culture : — 



" It naturally requires about six that are well drained, and filled with a 



months' rest, and will seldom start for 

 growth before March, when it will re- 

 quire a good bottom heat of at least80°, 

 either in a bark-pit or cucumber-bed. 

 The greatest error committed with re- 

 gard to its treatment is leaving the root 

 to start in the same pot, &c., it grew in 

 in the previous year. As it makes its 

 shoot from the lower end of the new 

 tuber, which is consequently at the bot- 

 tom of the pot, if it is not taken out, 

 and that end placed upwards, it has to 

 struggle through the whole mass of 

 mould to reach the surface, which it 

 often fails in doing. It should be potted 

 at the beginning of March in a forty- 

 eight pot ; or, if the tuber (which some- 

 times happens) is too long, a bulb-pot 

 may be used. It should be well drained, 

 and planted in pure light peat or heath 

 mould, with the end of the root just 

 above the surface. When it makes a 

 shoot, it also forms fresh roots from the 

 base of the new shoot, and will grow 

 rapidly if kept in a stove or vinery at a 

 temperature of 70^ or 80', and soon 

 requires a larger pot. It generally 

 takes a six, using nothing but light peat 

 soil. 



" It may then be trained in any form 

 most convenient. After it has flowered 

 and the leaves are decayed withhold 

 water entirely to ripen the tubers, which 

 may be kept in the dry mould till the 

 spring, or taken out and kept in dry 

 sand till the season for potting them."

GLOSSODIA. Two species. Green- 

 house orchids. Offsets. Sandy loam 

 and peat. 



GLOXINIA. Five species. Stove 

 herbaceous perennials. All are propa- 

 gated by seed, but G. maculata is also 

 increased by division; and the others 

 by leaves taken off" close to the stem. 

 Loam, peat, and sand, with leaf mould. 



Varieties. — Many varieties have been 

 raised by cross-impregnation, but for a 

 private garden the following may be 

 recommended: — G. corcineus ; G. 

 Youngii ; G. Manglesii; G. rubra; G. 

 Maxima ; G. speciosa ,- and G. Candida. 



Mr. J. McI., of Hillsborough, gives 

 the following directions for the culture 

 of these flowers : — 



"Propagation. — The gloxinia is rea- 

 dily increased by seeds and cuttings; 

 the seeds should be sown very thinly, 

 as soon as they are gathered, in pans
