THE TItUE CYPEESSES. 85 



obliquely outwards, and flattened. Cones globular, eight or 

 ten lines in diameter, very glaucous, smooth, and with eight or 

 ten scales in each. Scales elevated, shield-shaped, and convex 

 in the centre, terminated by a short prickle, and containing 

 under each several flattish winged seeds of a light brown 

 colour. 



A handsome, vigorous tree, with a conical head, and all the 

 principal shoots of a beautiful glaucous violet, or reddish plum- 

 colour, growing 120 feet high, and two and a half to three feet 

 in diameter, on the mountains of Mexico. It is much hardier 

 in England than Cupressus Benthami, a kind with which it 

 has been confounded by some writers, on account of their 

 never having seen the living tree ; but Mr. Perry, a very ac- 

 curate observer of Conifers, many years ago detected the mis- 

 take, and named this kind in compliment to Mr. Knight, of 

 Chelsea. It has since received other names, as indicated above. 

 Timber excellent. 



A fine, strong, growing kind, with the younger branches of a 

 violet or glaucous colour, and the handsomest and hardiest of 

 the Mexican kinds. 



Cupressus Knightiana variegata, Hort. 



Syn. Cupressus Lindleyi argentea variegata, Hort. 



A nice variety, with a portion of the branchlets of a silvery 

 white colour. 



No. 9. Cupressus Lawsoniana,* Murray, Messrs. Lawson's 



Cypress. 



Syn. Chamascyparis Boursierii, Carriere, not Decaisne. 

 Lawsoniana, Parlatore. 



* Among the innovations of some modern botanists, so prolific in the 

 confusion of practical botany, this and Cupressus Nutkaensis have been 

 removed to the genus Chamaecyparis, although both of them have three 

 or more seeds freely inserted on the upper surface of each scale, as in 

 the genus Cupressus, and consecmently not in accordance with the genus 

 Chamaacyparis, which has but two seeds under each scale, and in sunken
