LITERATURE OF THE CONIFEK2G. 51 



gave a new character to the Thuja artiatlata of Desfontaines, which 

 he named Callitris. M. Mirbel, in 1812, separated Ciipressus disticha 

 from the other species of that genus, and described it under the name 

 of Sehubertia, a name which has not been generally adopted because 

 it was found that M. Eichard senior had already described it under 

 the name of Taxodium. Mirbel also added the genus Frenela. In 

 M. Richard's Memoire stir les Coniferes, published in 1826, the author 

 endeavours to establish the throe groups or sections of Taxinese, 

 Cupressinese, and Abietineas, adding Phyllocladus to the first named. 

 It is this arrangement, as modified by Dr. Lindley, in his Introduction 

 to the Natural System, published in 1836, * that Loudon followed in 

 his Arboretum et Fruticetum, published two years afterwards. In 

 Dr. Lindley's arrangement, the section Taxinese is removed from the 

 Coniferae, and made a separate Order under the name of Taxacese, a 

 distinction which was retained through all the editions of The Vegetable 

 Kingdom. Loudon's proof sheets of that portion of the Arboretum et 

 Fruticetum Britannieum which contains the description of the Coniferae, 

 were corrected by Professor Don, whd for many years had charge 

 of the valuable Herbarium of Mr. Lambert, and who had assisted, if 

 he did not take the chief part, in the compilation of TJie Genus Pinus. 

 Don separated the Silver Firs from Abies, and constituted them a 

 new genus under the name of Picea, thus adhering to the Linneean 

 designation of Picea for the Silver Firs, and Abies for the Spruces, 

 which reversed the names of Pliny and the ancient Naturalists. This 

 change was not accepted by Sir W. Hooker,! Dr. Lindley, £ and other 

 contemporaries of Don. He founded the genus Cryptomeria on Thun- 

 berg's Cwpressus pendula, till his time scarcely known to Europeans 

 except by name. § He also added the Tasmanian genus Athrotaxis, |J 

 Don died in 1840, Lambert in 1842, and Loudon in the following 

 year. 



The Pinetum Wobumeme, by Forbes, containing coloured plates and 

 descriptions of the Coniferae cultivated at Woburn Abbey, the seat of 

 the Duke of Bedford, was distributed shortly after the publication 

 of Loudon's Arboretum. Siebold and Zuccarini's Flora Japonica was 

 published in 1842, of which a reprint of vol. ii., containing the Coniferse 

 of Japan was issued in 1870, with some additional information collected 

 by Dr. Siebold during his last visit to that country. Four new genera 

 are described in this work, viz., Sciadopytis, Thujopsis, Cephalotaxus,

 repudiation of the so-called genus Picea, which had been attributed to him by the 

 Editor of the Pinetum Britannieum.
