PlCEA Pinsapo GLAUCA, Hort, the Glaucous Pinsapo Fir. 



This is a very handsome variety, with the leaves, equal in 

 length and thickly placed at right angles round the shoots. 

 The leaves are very rigid, half an inch long, blunt-pointed, 

 somewhat rounded, and quite glaucous on the upper surface, 

 and with two conspicuous glaucous white bands beneath, sepa- 

 rated by the mid-rib, which is, as well as the margins, of a 

 bright-green colour. 



It is a very fine variety on account of its silvery appearance, 

 and is in the nurseries of Mr. Smith, of Worcester, and Mr. 

 Scott, at Merriott, in Somersetshire. 



Pinus Strobus compacta, Hort, the Compact or Bushy Wey- 

 mouth Pine. 

 This variety forms a dense, compact, round-headed bush, 

 from four to six feet high, and is very distinct from the Strobus 

 nana, with which it is sometimes confounded in the Nurseries. 



Retinospora filifera gracilis, Hort, the Slender, Thread- 

 branched Japan Cypress. 

 This variety differs from the original form, in being much 

 slenderer in all its parts, and of a much brighter green colour. 

 It produces numerous long, slender, drooping shoots, which are 

 frequently from five to six inches in length, before they pro- 

 duce any branchlets, and the branchlets, which are mostly 

 produced in tufts near the ends of the branches, have quite a 

 tasselled appearance. 



Retinospora obtusa alba spica, Barron, the White Speckled, 

 Obtuse-leaved Japan Cypress. 



This variety is similar in general character to the ordinary 

 form of the species, but rather more compact in habit. The 

 young shoots are pure white when first they appear in the 

 spring, and remain so for about three months, when they 

 gradually change, and finally become green. 



A nice, distinct variety.
