Retinospora plumosa alba variegata, Hort, the White 

 Variegated Plume Japan Cypress. . 



This is a charming variety, with bluish-gray foliage, dis- 

 tinctly and beautifully variegated with clear white spots, which 

 gives the plant the appearance of being covered with small 

 snow-flakes throughout the year. 



Retinospora plumosa aurea pumila, Hort, the Little Golden 



Plume Japan Cypress. 



This is a very neat, dwarf variety, which differs principally 

 from the plumosa aurea, in being very much dwarfer and 

 smaller in all its parts. 



It is an elegant little plant, with all the ends of the young 

 growth of a beautiful golden colour, during the spring and 

 summer months. 



Retinospora plumosa flavescens, Cripps, the Yellowish 



Plume Japan Cypress. 



This is a nice pale form of the plumosa aurea, with the ends 

 of the young shoots of a greenish-yellow colour. 



Retinospora tetragona, Barron, the Square-branchletted 



Japan Cypress. 

 Syn. Chamsecyparis thujseformis, R. Smith. 

 This kind forms a dwarf, compact, slow-growing shrub, of a 

 remarkably bright-green colour ; the secondary branchlets and 

 small spray are short, crowded, four-sided, and of a very bright 

 green; the leaves are ovate, a little pointed, closely and regularly 

 imbricated, in four rows, and of a beautiful bright glossy green 

 colour. 



A very distinct kind, recently obtained from Japan by Mr. 

 Barrou, of the Elvaston Nursery, and Mr. R. Smith, of Wor- 

 cester, and of which Mr. Barron has a nice variegated form, 

 with a portion of the lesser branchlets of a rich golden colour.
