and Reginae. Racemosa is hardy. Japonica and most of the 

 indoor species are propagated by cuttings of ripe wood, preferably 

 in bottom heat; Veitchii gracillima by grafting; racemosa by 

 division. Soil: 3 parts loam, i leaf mould, i peat, % part sand. 



Araucaria (arauca-ria, from the Araucanos tribe. Ord. Coniferae). 

 A large genus of Conifers, which embraces the well-known Monkey 

 Puzzle, imbricata, one of the few really hardy kinds, and a con- 

 spicuous object in the pleasure grounds of many places. Excelsa 

 is the most important of the greenhouse species, and it has several 

 varieties, such as glauca, Goldieana, and variegata. They make 

 nice table plants. All are evergreens. Propagated by cuttings, 

 the tops of plants being first struck, and then the shoots which start 

 from the old stumps; they root readily in sandy loam and leaf 

 mould in a greenhouse if kept shaded. Soil: 3 parts loam, i leaf 

 mould, j- part sand for the pot plants. The Monkey Puzzle is not 

 very fastidious, but does best in a deep, well-drained, loamy soil. 



Arbor vitae (Thuya). Cheap, hardy, and easily grown ever- 

 greens, often used for hedges, as well as for individual effect. When 

 planted for forming hedges they should be inserted about 9 ins. 

 apart. They are not quite so cheap as Privet and Thorn, but have 

 a little more distinction. The American Arbor vitae (Thuya occi- 

 dentalis) is the species most largely used for this purpose. Propa- 

 gated by seeds or cuttings. Almost any soil that is deep, substan- 

 tial, and well drained will suit. See also Thuya.

 Arbutus, Strawberry Tree (arbu-tus, from arboise (Celtic) , referring 

 to the rough fruit. Ord. Ericaceae). Arbutus Unedo is a hand- 

 some evergreen shrub, growing from 8 to 15 ft. high, and bearing 

 white flowers in September, which are followed by scarlet fruits 

 somewhat resembling Strawberries. There are pink and red- 

 flowered varieties of it. It is hardy, 

 generally speaking, though it may be 

 injured in severe winters if planted in 

 an exposed place in a cold district. 

 Propagated by seeds sown in spring. 

 Warm, well-drained peaty soil is de- 

 sirable.
