2462 ARBORETUM AND FRUTCETUM. PART III. 



owing to the scales which compose the cone being more closely adpressed 

 than they are in Cupressus. In some species of /uniperus, and in some 

 individual berries of other species, such as J. phoenicea, J. drupacea, &c., 

 the scales appear quite distinct, and they terminate in horny-looking prickles 

 or appendages, which give the fruit fully as much the appearance of a Cu- 

 pressus as of a <7unf perus. 



App. i. Species not sufficiently known to be referred to any of 

 the preceding Sections. 



T. fiUformis Lodd. Cat., ed. 1836. There are plants in the Hackney arbo- 

 retum, but they are too small to enable us to determine anything respecting 

 them. 



T. dolabrala Lin. Suppl., p. 420 , Thunb. Jap., p. 266., Willd. Sp. PL, 4. p. 509., Lamb. Pin., 

 ed. 2., t. 68., 'from a specimen in Kamipfer's herbarium, at the British Museum ; Quai, vulgo Fi 

 no kf, and Ibuki, Ktempf. Amcen., p. 884. Branchlets 2-edged. Cones squarrose. Leaves broad- 

 ovate, obtuse, imbricated in ,'> rows, white, and hollowed beneath. (Lamb. Pin.) A large, lofty, 

 and very handsome tree. Branchlets very numerous, alternate, flattened, irregularly divided. 

 Leaves imbricated in 3 rows, ovate, obtuse, thick, much larger than in the other species; convex 

 above, of a beautiful green, shining, furrowed in the middle ; .concave, margined, and white 

 beneath. Cones squarrose. A native of Japan, where Thunberg 'observed it in the countries of 

 Oygawa and Fakonia, between Miaco and Jedo, and found it planted along the high road on the 

 hill of Fakonia. He speaks of it as a tree of vast height and dimensions, the most beautiful of all the 

 evergreen tribe, but it has not yet been introduced. Mr. Lambert states that he has no doubt of its 

 being perfectly hardy. 



Other Species. There are various names in nursery catalogues, but the plants to which they are 

 applied bear so close a resemblance to those already described, that we cannot venture to consider 

 them distinct.

Description, &c. Evergreen low trees, natives of Africa and Australia, and 

 requiring, in England, the protection of a green-house. This genus was esta- 

 blished from the Thuja articulata of Desfontaines. It differs from the genus 

 Thuja in having the scales of the female catkins constantly from 4 to 6, all 

 opening like the valves of a regular pericarp ; and in having, at the base of 

 each of these scales, a number of seeds winged on the margin.

Spec. Char. Leaves flattened, articulate. Female catkin tetragonal, with 4 

 oval valves, each furnished with a point, and 2 of which bear seeds. (Desf.) 

 A low tree; a native of Barbary. Introduced in 1815, and flowering 

 from February to May. 



Description y fyc. A tree, attaining the height of from 15 ft. to 20 ft., accord- 

 ing to the soil and situation in which it grows, with a trunk from 1 ft. to 3 ft. 

 in diameter. Branches forming an open angle with the trunk, with nume- 

 rous smaller shoots, flattened, striated, articulated, fragile, and of a green 

 colour. Articulations enlarged at their summit ; about 3 lines in breadth, and 

 from 9 to 10 lines in length. Leaves very small; straight, unequal, and mu- 

 cronate, with very small glands at their base. Flowers monoecious. Male
