large and highly ornamental tree, producing useful and valuable 

 timber. It should be grown extensively in every collection. 

 Several beautiful varieties have been raised, and are now much 

 grown in this country, amongst which may be named C. L. alba- 

 spica, argentea, argenteo-variegata, aureo-variegata, erecta viridis, 

 Jiliformis, gracilis, lutea nana, and j'lygincHa. 



C. lusitanica (the Cedar of Goa). — Introduced in 1G83, and 

 .said to be from the East Indies. Height, 50 feet. A remarkably 

 handsome low tree, but not very hax'dy in Britain. 



C. 7nacrocarpa (the Large-fruited Cypress). — Introduced in 1838. 

 Habitat, Upper California. Height 80 feet. This is a tree of 

 very pleasing effect, but only moderately hardy, and impatient of 

 cold cutting winds. 



C. m. Lamhertiana (Lambert's Cypress). — Introduced about 

 1840. This is generally considered a variety of G. macrocarpa. 

 From a parcel of seed received from a well-known collector in 

 California upwards of a dozen varieties were raised, amongst them 

 the true type of C. Lamhertiana ; and I therefore conclude that 

 they are merely seminal varieties. 



G. ^utkaeiuis (the Nootka Sound Cypress). — Habitat, British 

 Columbia and Oregon. Introduced about 1850. This is, per- 

 haps, better known as Thuiopsis borealis, and has a considerable 

 resemblance to G. Latvsoniana, but is a more robust growing tree, 

 with a paler green aspect. In its native country it attains a height 

 of 80 to 100 feet, and produces yellowish fragrant wood, light, 

 easily worked, and durable, and valuable for all open-air purposes. 

 It is one of the hardiest, as well as one of the most beautiful, of 

 all the cypress tribe, and thrives well in favourable sites. Being 

 one of the best and most useful of ornamental conifer's, it should 

 be freely introduced by all planters. There are several variegated 

 varieties, all of which are valuable as ornamental ti'ees. 



G. sempervirens (the Common Cypress). — Introduced before 

 1548. Habitat, South of Europe, Greece, Turkey, Persia, and 

 Asia Minor. The tree is of a pyramidal or upright habit of 

 growth, and attains a height of 50 to 100 feet. Its wood is hard 

 and fragrant, of a remarkably fine close grain, and is very durable, 

 having a beautiful reddish hue, and is a most valuable tree in its 

 native country. It is used in Britain as an ornamental tree. 



In 1803 a tree of G. s. Jiorizontalis, growing in Chelsea Botanic 

 Gai-den, when measured by Lord Aberdeen, Avas found to be 150 

 feet in height and 24 feet in circumference at four feet from the
