as sections only Picea, Link, Abies, Link, Cedms, Larix, 

 Pseudolarix, Tsuga, and Pseudotsuga. The species 

 described are 162. 



In 1875 the second edition of Gordon's Pinetum was 

 published, in which the same genera are retained as in 

 the 1858 edition, with 150 species. 



Lastly, in the Genera Plantarum (1882), Mr. Bentham 

 and I have distinguished Pimis, Picea, Link, Abies, 

 Link, Tsuga, Pseudotsuga, Larix, and Cedrus, to which 

 must now be added Pseudolarix and probably Keteleeria, 

 both at that time very imperfectly known. 



In 1886 Dr. M. T. Masters published {Journal of the 

 Linnean Society, xxii. pp. 169-212, tt. 2-10, with 32 

 woodcut figures in the text) some " Contributions to 

 the History of certain Conifers." This was followed 

 in 1890 by a " Review of some points in the comparative 

 Morphology, Anatomy, and Life History of the 

 Coniferae" (Journ. Linn, Soc, xxvii. pp. 226-332, 

 with 29 woodcut figures in the text), and in 1895 by 

 " Notes on the Genera of Taxaceae and Coniferae " 

 (Journ. Linn. Soc, xxx. pp. 1-42). 



In 1889, two years after his death, Dr. A. W. Eichler's 

 elaboration of the Coniferae appeared in Engler and 

 Prantl's Die Naturlichen Pflanzenfamilien. He classifies 

 the genera under two primary divisions : Pinoideae and 

 Taxoideae. The former he again divides into Abietineae 

 and Cupressineac, with several ternary divisions, and the 

 latter into Podocarpeae and Taxeae. The genera are 

 limited, with few exceptions, as they are by Bentham 

 and Hooker ; but he retains Chamaccyparis, Thuioims
