1438 The Trees of Great Britain and Ireland 



A dense low tree, columnar in habit, with slender elongated pendulous branchlets; 

 leaves bright green, acicular, like the juvenile foliage of J. virginiana. This hand- 

 some tree was first mentioned by Loudon, who merely states that it closely resembles 

 J. virginiana. Its origin is unknown, 1 but it is usually considered to be identical 

 withy, barbadensis, and the fact that it is rather tender in England supports this 

 view. As it has only juvenile foliage, and apparently never bears fruit, the question 

 cannot be decided. 



IV. Many varieties of J. virginiana, which are always propagated by cuttings, 

 have arisen in nurseries, no less than twenty-one varieties being enumerated in the 

 Kew Hand- List. According to Loudon, it varies much when raised from seed, as at 

 White Knights, where there were hundreds of trees in 1838, differing much in 

 appearance. Some were low and spreading, others were tall and fastigiate, and some 

 had pendulous branches. The foliage varied much in colour, being light green, dark 

 green, or glaucous. The fruit also differed in size. The most important varieties 

 are : 



1. Var. pendula, Knight, Syn. Conif. 12 (1850). 

 This exists in at least three forms : 



(a) Branches spreading, branchlets pendulous, leaves scale-like, bearing staminate 

 flowers. 



(b) Var. pendula viridis. Branches and branchlets pendulous ; leaves scale-like, 

 bright green. 



(c) Var. Chamberlainii, Knight, loc. cit. Branches spreading and reflexed ; 

 branchlets pendulous ; leaves mostly acicular, of a greyish tint. 



2. Var. pyramidalis, Carriere, Conif. 47 (1867). 



Columnar in habit, with either glaucous or bright green foliage. 



3. Var. dumosa, Carriere, Conif. 45 (1855). 



A dense rounded shrub, with both acicular and scale-like leaves. 



4. Var. Schottii, Gordon, Pinetum, 157 (1875). 



A narrow pyramidal tree, dense in habit, with bright green scale-like leaves. 



5. Var. tripartita, R. Smith, ex Gordon, Pinetum, 157 (1875). 



A low spreading bush with dense branches, and bright green, usually acicular 

 foliage. , 



6. Var. glauca, Knight, Syn. Conif. 12 (1850). 



Differs from the type in its beautiful glaucous silvery foliage, which is most 

 pronounced in spring. 



7. Var. Triomphe d Angers, Beissner, Nadelholzkunde, 127(1891). 



Young branchlets creamy white, contrasting well with the dark bluish-green of 

 the older foliage. 



8. There are several variegated varieties, as alba variegata and aurea variegata, 

 Gordon, Pinetum, 157 (1875), which are usually poor in colour. 



9. Var. elegantissima, Beissner, Nadelholzkunde, 128 (1891). 



A pyramidal tree, with the tips of the young branchlets golden yellow. 



1 There appears to be no ground for Loudon's statement, Trees and SAruis, 1118 (1842), that it is identical with 

 J. gossainthanea, Loddiges, as the latter and J. Bcdfordiana are kept distinct by Knight and Perry, Syn. Conif. n, 12, 13 

 (1850). Endlicher states that_/. Bcdfordiana is a native of Mexico.
