CONIFER7E. 
On going to press the Secretary has received from Prof. A. 
Henry, with the request that it be noticed in the Report, an 
excellent and well illustrated article of 72 pp. (10|" X 7j") and 
seven plates entitled Conifer ce : Keys to the Genera and Species, 
with Economic Notes. The work is by H. M. FitzPatrick, 
B.Agr.Sc., a past student of Prof. Henry, to whom is made 
full acknowledgement for indebtedness. It forms No. 19, 
Vol. 19, N.S. of the Scientific Proceedings of the Royal 
Dublin Society, April, 1929. The London publishers are 
Williams and Norgate, and the price 8/-. 
The object of the author was the compilation of “a com- 
prehensive series of descriptions of the species of the Coniferae, 
based on the morphology of the foliage, arranged in the form 
of an artificial key. . . . Living trees must be identified by 
means of peculiarities of the foliage alone in youth, and later 
in life also if they are not bearing cones. Workers in palaeo- 
botany recognise fossil remains of plants in many cases by 
the impressions of leaves and twigs, and for such work keys 
are essential.” It is pointed out that in the Abietineae the 
twigs become woody in the second year of growth, and this 
distinguishes this important timber-producing tribe from all 
other Conifers except Taxodium. 
The classification first divides the five families into forty- 
seven genera, with the number of species and geographical 
distribution of each genus. Then follows a useful and up-to- 
date Key to the Genera. The main body of the work is 
devoted to an excellent Description of Genera and Species, a 
few lines being given to over 300 species out of a total of 490 
living species. 
The work should be of great use to botanists, geologists, 
foresters and nurserymen, and was much needed in this 
country. The plates, with 95 figures of twigs and leaves, are 
admirably clear.
