198 The Trees <strong>of</strong> Great Britain and Ireland A shrub, with a straight trunk, bare <strong>of</strong> branches below. The branchlets, numerous, long, flexile, cord-like, unbranched or only slightly branched, are produced in irregular fascicles <strong>of</strong> 5 to 20 or more at irregular intervals along <strong>the</strong> branches. They are slender and pendent, and bear leaves distantly placed in 4 rows in decussate pairs. The leaves, broadly decurrent at <strong>the</strong> base and long acuminate at <strong>the</strong> apex, spread out from <strong>the</strong> branchlets at an acute angle. Cones are occasionally borne, which are like those <strong>of</strong> <strong>the</strong> type. 1 There is a specimen at Kew <strong>of</strong> a plant raised from seed <strong>of</strong> this variety, which is ordinary Thuya orientalis. It was sent from <strong>the</strong> Botanic Garden at Turin by Mr. Hanbury in 1860. There are several forms <strong>of</strong> this variety, differing in habit and length <strong>of</strong> leaves; in one <strong>the</strong> branchlets are tetragonal. This shrub was first observed by Thunberg in Japan, and specimens were collected near Yokohama by Maximowicz. It was also met with by Fortune in China, and has been raised in Europe. 2. Var. decussata. Retinospora juniperoides, Carribre, Conif. ed. 2, p. 140. A low shrub, with erect stems and branches, bearing foliage like that <strong>of</strong> <strong>the</strong> seedling. The leaves are in 4 rows in decussate pairs, spreading, and resembling those <strong>of</strong> a juniper, except that <strong>the</strong> points are not prickly. They are greyish green in summer, changing to brown in winter. 3. Var. Meldensis. Biota Meldensis, Lawson, in Gordon, Pinetum, 3 7. A small tree with ascending flexible branches. It is a transition form, bearing acute acicular spreading leaves like that <strong>of</strong> <strong>the</strong> seedling, and occasionally leaves <strong>of</strong> <strong>the</strong> adult character. The leaves are bluish green, changing to brown in <strong>the</strong> winter. This plant was raised from seeds <strong>of</strong> Thuya orientalis ga<strong>the</strong>red in <strong>the</strong> cemetery <strong>of</strong> Trilbardoux near Meaux in France; and for a long time was supposed to be a cross between Thuya orientalis tt\.&Juniperus virginiana. 4. Var. intermedia. Biota orientalis intermedia, Carriere, Man. des PI. iv. 322. This is also a transition form. It is a shrub with elongated pendent branchlets, <strong>the</strong> ramifications <strong>of</strong> which arise from all sides <strong>of</strong> <strong>the</strong> axis, not remaining in one plane. There are two kinds <strong>of</strong> leaves, those towards <strong>the</strong> ends <strong>of</strong> <strong>the</strong> branchlets resembling <strong>the</strong> adult foliage <strong>of</strong> Thuya orientalis, while those on older parts are spreading, arranged in decussate pairs, oval-lanceolate, decurrent at <strong>the</strong> base, and acute at <strong>the</strong> apex. In Var. funiculata, if it is in reality distinguishable, <strong>the</strong>re appears to be a larger proportion <strong>of</strong> adult foliage. Many o<strong>the</strong>r varieties have been described: some <strong>of</strong> peculiar habit, as gracilis and pyramidalis, which are fastigiate ; o<strong>the</strong>rs with coloured or variegated foliage, as aurea, argenteo-variegata, aureo - variegata. Var. ericoides <strong>of</strong> this species closely 1 At Barton, a shrub <strong>of</strong> this variety produced cones, which had very long hooked processes on <strong>the</strong> scales (Bunbury, Arboretum Notes, I S3)- Thuya 199 resembles <strong>the</strong> variety <strong>of</strong> <strong>the</strong> same name belonging to Thuya occidentalis ; <strong>the</strong> latter is slightly whiter on both surfaces <strong>of</strong> <strong>the</strong> leaves. DISTRIBUTION, ETC. Thuya orientalis occurs wild in <strong>the</strong> mountains <strong>of</strong> north China. It is common in <strong>the</strong> hills west <strong>of</strong> Pekin, where Fortune 1 observed <strong>trees</strong> <strong>of</strong> a large size, 50 or 60 feet in height. Elsewhere in China it is only met with planted in cemeteries and temple grounds. It has been known to <strong>the</strong> Chinese from <strong>the</strong> earliest times as <strong>the</strong> Poh or Peh tree, and is mentioned in <strong>the</strong>ir classical books; it was planted around <strong>the</strong> graves <strong>of</strong> feudal princes, and its wood was used for making <strong>the</strong> c<strong>of</strong>fins <strong>of</strong> <strong>great</strong> <strong>of</strong>ficials. The tree was introduced into Japan from China at an early period, probably like so many o<strong>the</strong>r Chinese plants, by <strong>the</strong> Buddhist missionaries. Japanese botanists are all agreed that it is not indigenous in Japan. Various o<strong>the</strong>r regions have been mentioned as being <strong>the</strong> home <strong>of</strong> Thuya orientalis, as Siberia, Turkestan, Himalayas, etc.; but specimens collected in <strong>the</strong>se countries are undoubtedly from cultivated <strong>trees</strong>. The tree is mentioned by Gmelin in his Flora Siberica, i . 182 (1747); but only as occurring between Kiachta and Peking. Ledebour 2 denies its existence in any part <strong>of</strong> Siberia. Thuya orientalis was first grown in Europe at Leyden, some time before 1737, when Linnaeus 3 described <strong>the</strong> plant as Thuya strobilis uncinatis squamis reflexa acuminatis. Royen, who sent a specimen to Linnaeus, mentions <strong>the</strong> species with considerable details in his account 4 <strong>of</strong> <strong>the</strong> plants that were cultivated at that time in <strong>the</strong> Botanic Garden at Leyden; but his promised account <strong>of</strong> <strong>the</strong> history <strong>of</strong> its introduction apparently never was published. It is possible that it was raised from seed sent home by <strong>the</strong> Dutch from Japan, as Kaempfer, who travelled in that country from 1690 to 1692, collected specimens <strong>of</strong> Thuya orientalis which are still preserved in <strong>the</strong> Natural History Museum at South Kensington.5 Seeds were also soon afterwards sent to Paris by <strong>the</strong> missionaries in north China. 6 The earliest account <strong>of</strong> it in England occurs in a letter dated February i, 1743, from <strong>the</strong> Duke <strong>of</strong> Richmond to Collinson, as follows: " I am sorry to find by Miller that I am not likely to have <strong>the</strong> Chinese Thuya. I own, if it belonged to anybody that would sell it, I should be foolish enough to <strong>of</strong>fer ten guineas for it, because it is <strong>the</strong> only one in England that can match that which I have already." It was cultivated early by Miller 7 in <strong>the</strong> Physic Garden at Chelsea. Thuya orientalis never attains in this country any considerable dimensions. It ripens good seed; and at Kew, on a wall near <strong>the</strong> Director's <strong>of</strong>fice, may be seen a 1 Yedo and Peking, 307, 382 (1863). Fortune supposed that <strong>the</strong> wild tree in north China was distinct from that cultivated near Shanghai'; but <strong>the</strong>re is no doubt that <strong>the</strong> <strong>trees</strong>, which attain a <strong>great</strong> size in <strong>the</strong> hills west <strong>of</strong> Peking, are ordinary Thuya orientalis. 2 Comment, in Gmelini Fl. Sibericam, 60(1841). 3 Hart. Cliff. 449 (1737). 1 Flora Leydensis ProJromus, 8 7 (1740). 6 I have seen <strong>the</strong>se specimens. See Salisbury, Coniferous Plants <strong>of</strong> Kaempfer, \r\Jour. Science and Arts, ii. 313 (1817). Kaempfer does not mention <strong>the</strong> plant in his Amamitates Exotics. 0 See Miller, Card. Diet. ed. 6 (1752), and ed. 8 (1768), snt> " Thuya." ? Cf. Aiton, Hoi-t. Kem. iii. 371 (1789).
2OO The Trees <strong>of</strong> Great Britain and Ireland young tree which originated from a seed probably carried <strong>the</strong>re by a bird from a tree in <strong>the</strong> gardens. In <strong>the</strong> garden at Hampton Court, Herefordshire, <strong>the</strong>re are a pair <strong>of</strong> fine specimens about 40 feet high, and about 7 feet round at <strong>the</strong> base, where <strong>the</strong>y divide into several stems which have been formed into an arch over <strong>the</strong> path, and in most old gardens <strong>trees</strong> <strong>of</strong> 25 to 35 feet may be found, but, like T.japonica and T. occidentalis, I it must be looked on as an ornamental shrub ra<strong>the</strong>r than a timber tree. | (A.
