n. PREFACE. 



luxuriantly with us, although, some kinds of the first seem to have a 

 short duration of life in South Australia, especially Cupressus macrocarpa 

 Harhv., -which, after a very rapid growth, dies suddenly when about 

 twelve to sixteen years old- Wellingtonia gigantea does not delight in 

 our climate, although growing the first year tolerably well, but later it 

 ceases to grow, and dies slowly. 



Very few of the Himalayan conifers prosper in the plains, especially 

 such as appear at an elevation of 7,000 to 8,000 feet, viz , Ahies 

 Sniithiana Loud., Brunoniana Lindl., Picea Pindrow Loud., Wehhiana 

 Loud., Pinus Gerardiana, Wall., excelsa Wall, &c. Their growth is 

 very slow, and they succumb in a few years to the droughts and hot 

 winds. , Only Cedrus Deodara Roxb. and Pinus longifolia Roxb. doing 

 well with us, although Cedrus Deodara in their native state appear at 

 an elevation of from 5,000 to 12,000 feet. 



Still more difficult is the existence of the Japan conifers. None will 

 prosper luxuriantly out of doors with us. Thuiopsis, Retinospora, 

 Chamaeccyparis, Cryptomeria are of a lingering growth, and much 

 injured by hot winds and droughts. The beautiful umbrella pine 

 Sciadopitys verticillata Siebold. can scarcely be kept alive indoors. 

 None of the Taxus, may they be natives of Europe, America, cr East 

 India, prosper with us. 



I have already pointed out that some of the tropical trees and shrubs 

 do not object to our climate, and thrive tolerably well. I will only 

 mention the most noteworthy. 



Of 'the Chinese and Japanese flora Paulownia imperialis Siebold, 

 Laurus Camphora Willd., Broussonetia papyrifera Vent., Stillingia 

 sebifera Michx. , Aralia papyrifera Hoolc. , Koelreuteria paniculatd Laxm. , 

 Sophora japonica Linn., Eriobotrya japonica Lindl., Rhus sucoedanea 

 Linn., Hibiscus rosa sinensis Linn., Euohymus japonicus, Linn., radicans 

 Zucc, &c. ; but the handsome Japanese maple, Acer polymorphum, 

 Spach., in its numerous varieties, despise our climate entirely. They 

 even will not grow in our greenhouses. 



From the East Indian flora the following genera thrive well with us in 

 the open air, viz. : — Erythrina, Rhaphiolepis, Bauhinia, Lagerstroemia, 

 Ouillandia, Poirtciana Gillesii Hooh. Poinciana pulcherrima Linn, is 

 too tender. 



The Chinese, Japanese, and East Indian Alpine plants, viz., camellias, 

 rhododendrons, azaleas, as already mentioned, will not stand our dry and 

 hot summers out of doors, but find a genial climate in the hills and 

 gullies, at an elevation of 1,000 to 2,000 feet, where they reach the same 

 perfection that we are used to see ttiem at home.
