"well if growers would adopt the nomenclature in the "Report of the 

 Conifer Conference" in Vol. XIV of the R.H.S. Journal, which has also 

 been followed in the Practical Guide to Garden Plants. The Silver Firs 

 most largely grown are the following, the heights given being those for 

 fully grown trees in a native state: amabilis, 100-150 ft.; balsamea, 

 70-80 ft.; bracteata, 150-200 ft.; concolor, 100-130 ft., with a lovely blue- 

 green variety, violacea', grandis, 200-300 ft.; Lowiana, 300 ft.; magnifica, 

 200-250 ft.; nobilis, 200-300 ft. (fig. 450), all from North America. 



Amongst European and Asiatic species there are some very fine trees: 

 brachyphylla, 120 ft, Japan; cephalonica, 80-100 ft., Greece; firma, 

 100 ft., Japan; Nordmanniana, 80-100 ft., Caucasus; pectinata, the Com- 

 mon Silver Fir of Central and South Europe, with many varieties; Veitchi, 

 120-140 ft., Japan; Webbiana, 80-90 ft., Himalayas. Most of the above 

 are called " Picea " in nurserymen's catalogues. 



Arauearia imbricata (MONKEY-PUZZLE TREE). This noble-looking 

 Chilian Pine, with spiny -tipped and spirally arranged leaves, is well 

 known. It attains a height of 150 ft. in a native state, but rarely more 

 than 50 ft. in the British Islands. The Norfolk Island Pine (A. excelsa) 

 is dealt with in Vol. II at p. 127. 



Cedrus (CEDAR). The best-known species are the Deodar (0. Deodara), 

 largely grown, 150-200 ft., Himalayas; the Atlas Cedar (0. atlantica), of 

 which there are several varieties, including a silvery one, argentea, and 

 a blue-green one, glauca, 80-100 ft., Atlas Mountains; and the Cedar of 

 Lebanon (G. Libani), 80-100 ft., Asia Minor. 



Cephalotaxus. A genus of Japanese and Chinese Taxads, not largely 

 grown, and including drupacea, 20-30 ft; Fortunei, 40-50 ft.; and pedun- 

 culata (Podocarpus Icoraiana), 15-20 ft., with a variety fastigiata, resem- 

 bling the Irish Yew in habit. 



Cryptomeria japonica. A beautiful Chinese and Japanese evergreen, 

 130-150 ft., with several varieties, including elegans, viridis or Lobbi, 

 nana, and spiralis. 



Cunning-hamia sinensis. A remarkable Chinese tree, 40-50 ft. high, 

 rather too tender for most parts of the kingdom. There is a blue-green 

 variety, glauca. 



Cupressus (CYPRESS). Botanically this genus includes Chamsecy- 

 paris and Retinospora, but the latter is kept distinct in this work. 

 Amongst the Cupressus proper, Lawson's Cypress (C. Lawsoniana), from 

 California, and its many beautiful varieties, are raised in thousands from 

 seeds and cuttings every year. In a native state Lawson's Cypress grows 

 up to 200 ft. high, but the tallest trees in Britain are little more than 

 50-60 ft. high. Amongst the best varieties are erecta viridis, Allumi, 

 Fraseri, glauca, and several with silvery variegation (albo-variegata, 

 argentea, Silver Queen, &c.); and golden variegation (aureo-variegata, 

 lutea, &c.); some with more pyramidal habit (pyramidalis, albo-spica)', 

 and others like Triomphe de Boskoop, a pretty blue-green variety; versi- 

 color\ Wisseli, &c.
