of the former to one of tlie latter. Propagated by division of 

 the plants or by seeds. A. cyanea and A. pusiila, flower 

 blue. 



ARISTOLOCHIA. Birthwort. [Aristolochiaceae.] Hardy 

 greenhouse or stove herbs or shrubs, often with twining 

 stems. Soil for the tender sorts, rich loam and peat in equal 

 parts ; plenty of root room. Propagated by cuttings in sand, 

 with bottom heat. The stronger growers seldom bloom well 

 unless planted out, and their branches trained near the 

 glass. The smaller kinds should have trellises put to 

 the pots when they are finally shifted. The best form is 

 round and round a pillar, formed of four or five stalks. Of 

 all the forms for supporting climbing plants the pyramid is 

 the worst; for as the branches increase in number as the 

 specimen advances, and in no possible case are lessened, 

 there is the more surface required the higher it goes; so 

 that lessening it is a positive evil, and leads to the ends of 

 the shoots all coming together in confusion. For the hardy 

 sorts, common garden soil ; the shrubby sorts being increased 

 by layers, and the herbaceous sorts by division. A. caudata^ 

 deciduous twining stove shrub, flowers livid purple. A. cym- 

 bifera, stove climbing shrub, flowers yellow and purple. A. 

 sipho, yellow and brown, and A. tomentosa, purple, are hardy. 



APtiSTOTELIA. [Tiliacese.] Hardy evergreen shrub. 

 Common soil. Propagated by layers. The only ones grown 

 are A. Macqui, flowers green, in May, and A. variegata. 



ARMEPdA. Thrift. [Plumbaginacese.] Dwarf herba- 

 ceous plants, nearly all hardy. Soil, sandy loam. Increased 

 by dividing the crown, and planting the separate pieces as 

 cuttings under hand-glasses. They are fine rock plants, and 

 also do well in pots ; and some varieties of the common Thrift, 

 especially a deep rose and a white one, make a pretty edging 

 to flower-beds. 



ARTANEMA. [Scrophulariacese.] Greenhouse perennial. 

 Soil, sandy loam and peat. Propagated by seeds, and sown 

 in March, or by cuttings of half-ripened shoots. A.jimhia- 

 tum, flowers pale blue, in August. 



ARTEMISIA. [Compositae.] Hardy and greenhouse 

 herbs and shrubs, with a few annuals, remarkable in many 

 cases for a strong heavy odour. A. abrotanum, the Southern-
