PART III,

Hynonytne. Fi-moro, Ktemtf. Amatn., p. 883.

Engravings. Lamb. Pin., ed. 2., t,. 66.; Staunt. Embass., t. 41.; our fig. 2332. to our usual scale ;

figs. 2333. of the natural size; and fig. 2334. showing parts of the shoots magnifiedSpec. Char., fyc. Branchlets 2.edged, leafy ; the oldest very long, pendulous;the younger short, alternate, 2-rowed, spreading. (Lamb.) A tree, with alarge expanded head. Branches dichotomous, loose, leafless, much divided :branchlets long, compressed, pendulous, closely covered with leaves; againdivided, secondary branchlets short, spreading. Leaves imbricated in + rows,rather stem-clasping, and triquetrous ; keeled, adpressed. Male catkinsnumerous, ovate, more than one line long, solitary on the apex of thebranches, sessile; female depressed, surrounded by spreading leaves, termi-nating the very short inferior branchlets. Cone brownish, about the sizeof a sloe. Scales 8-angled; mucros obtuse. Seeds yellowish. (Lamb.) Atree, a native of China , said to have been introduced in 1808, but re-specting which we know nothing with certainty. The pendulous cypress,or Thuja, at Chelsea, and in the Kew arboretum, may possibly be the same as Thunberg’s plant.

App. i. Kinds of Cupressus of ’which there are Plants in BritishGardens , but of which very little is known.

C. horixonidlis Audibert This plant has been already referred to, p. 2465., as being considered bysome to be the same as the spreading variety of C. sempervlrens; and by others, as a distinct species.As it has produced cones exactly resembling those of C. sempervlrens, we have no doubt of its beingonly the spreading variety of that species. The tree in the Horticultural Society’s Garden, receivedfrom Audibert in 1825, is now 6 ft. high, of vigorous growth, and with spreading branches.

C. expnnsa Audibert, ? C. exp&nsa Hort. Par. Toe tree received Irom Audibert’s Nursery atTarascon in 1834, and nowin the Horticultural Society’s Garden, was, in 1837, 2 ft. high. TheC.exp&nsa of the Hort. Par. is C. s. horizontalis.

C. FothergUlx Lee. A plant under this name is in the Horticultural Society’s Garden, which wasreceived from the Hammersmith Nursery in 1834. It is now 2 ft high, and is found rather tender.

C. thurifera. A plant in the Horticultural Society’s Garden, bearing this name, is only a fewinches high.

C. Tournefortn Audibert. The plant bearing this name in the Horticultural Society’s Garden,received from Audibert in 1834, is 2 ft. high.

C. bacciformis Willd. A hardy tree, 20 ft. high. Introduced in 1818.

C. australis Pers. A shrub, with slender branches, a native of New Holland, and rather tender.

Before anything can be determined with certainty respecting the above kinds, they must haveproduced fruit; and, consequently, several years must elapse. Most of them are probably onlysynonymes to species of Cupressus above described, or of some of the kinds of Jumperus which willhereafter be given.

App. ii. Kinds of Cupressus not yet introduced.

C. nootkaUnsis Lamb. Branchlets tetragonal. Leaves broad-ovate, acute, convex on theback, imbricated in 4 rows, adpressed. Galbulus globose, almost sessile. Scales bossed, smooth,(Lamb. Pin., ii. No. 60.) A tree. Branches round, spreading, scaly from the withered leaves,covered with a brownish bark. Branches numerous, somewhat distant, tetragonal, short, spreading.Leaves broad-ovate, acute, very thick, glabrous, shining, closely adpressed, imbricated in 4 rows,convex on the back; adult ones shortly awl-shaped at the apex. Galbulus globose, lateral, the size ofa wild cherry, covered with a glaucous hue, on a very short scaly footstalk, similar to a branchlet;scales trapezoidal, peltate, smooth, bossed in the centre. (Lamb.) Discovered by Mr. Menzies, inNootka Sound, on the north-west coast of North America .

C. japdnica Thunb . Jap., p. 265., Willd. Sp. PI., 4. p. 513., Lin. Supp., p. 421. Leaves 4-rowed,compressed, furrowed, decurrent. (Thunb .)

Genus XII.

TAXO'DIUM Rich. Thf, Taxodium, or Deciduous Cypress. Lin. Syst.Monoe'cia Monadelphia.

Identification. Rich. Conif., p. 143.; Lamb. Pin., ed. 2., 2.

Si/nonymes. Cupressus /,., Schub£rti« Mirb., Condylocarpus Salisb.

Derivation. From taxus , the yew, and eidos, like; the trees resembling the yew.

Description. Lofty, deciduous, and evergreen trees, natives of the southernpart of Nortli America; separated from the genus Cupressus, principally be-cause the male catkins are disposed in loose spreading bunches, instead obeing solitary and terminal; and because the female catkins are roundish anuscaly, like the male, and each scale has only 2 perfect flowers. The genus isalso distinguished by the embryo having from 5 to 9 cotyledons. The speciesare generally propagated by seeds, and the varieties by cuttings or layers.
