ARBORETUM AND FRUTCETUM.

PART III.

owing to the scales which compose the cone being more closely adpressedthan they are in Cupressus. In some species of Juniperus, and in someindividual berries of other species, such as J. phoenicea, J. drupacea, &c.,the scales appear quite distinct, and they terminate in horny-looking pricklesor appendages, which give the fruit fully as much the appearance of a Cu-pressus as of a Juniperus.

App. i. Species not sufficiently known to be referred to any ofthe preceding Sections.

T. filiformis Lodd. Cat., ed. 1836. There are plants in the Hackney arbo-retum, but they are too small to enable us to determine anything respectingthem.

Pin.,ed. 2., t. 68.,‘from a specimen in Kajmpfer’s herbarium, at the British Museum; Quai, vulgo Ftno hi, and Ibuki , Ka?mpf. Amoen., p.884. Branchlets 2-edged. Cones squarrose. Leaves broad-ovate, obtuse, imbricated in 3 rows, white, and hollowed beneath. {Lamb. Fin.) 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; convexabove, of a beautiful green, shining, furrowed in the middle ; jconcave, margined, and whitebeneath. Cones squarrose. A native of Japan, where Thunberg observed it in the countries ofOygawa and Fakonia, between Miaco and Jedo, and found it planted along the high road on thehill of Fakonia. He speaks of it as a tree of vast height and dimensions, the most beautiful of all theevergreen tribe, but it has not yet been introduced. Mr. Lambert states that he has no doubt of itsbeing perfectly hardy.

Other Species. There are various names in nursery catalogues, but the plants to which they areapplied bear so close a resemblance to those already described, that we cannot venture to considerthem distinct.

Description, &c. Evergreen low trees, natives of Africa and Australia, andrequiring, in England, the protection of a green-house. This genus was esta-blished from the Thuja articulata of Desfontaines. It differs from the genusThuja in having the scales of the female catkins constantly from 4 to 6, allopening like the valves of a regular pericarp; and in having, at the base ofeach of these scales, a number of seeds winged on the margin.

1 1. C. quadiuva'lvis Vent. The four-valved Callitris.

Spec. Char. Leaves flattened, articulate. Female catkin tetragonal, with 4oval valves, each furnished with a point, and 2 of which bear seeds. (Desf.)A low tree; a native of Barbary. Introduced in 1815, and floweringfrom February to May.

Description, S;c. 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 greencolour. Articulations enlarged at their summit; about 3 lines in breadth, andfrom 9 to 10 lines in length. Leaves very small ; straight, unequal, and mu-cronate, with very small glands at their base. Flowers monoecious. Male
