THE PARTS of Engler’s Pflanzenreich are appearing with remarkable 
rapidity. The eighth has now been published," containing the Aceraceae 
(family 163 of the spermatophyte series) by F. Pax. The two genera are 
Dipteronia, a monotypic Chinese genus, and Acer with 114 species, 8 of 
which are new. The monograph is admirable in its painstaking care. Thir- 
teen sections of Acer are recognized as follows: I. Sicata (30 spp.), Il. 
Palmata (6 spp.), Ill. Trifoliata (6 spp.), 1V. Zntegrifolia (6 spp.), V. /ndi- 
oe visa (g spp.), VI. Rubra (4 spp.), VII. Megundo (3 spp.), VIII. Glabra (1 sp.) 
IX. Platanoidea (13 spp.), X. Campestria (10 spp.), XI. Macrantha (12 
spp.), XII. Lithocarpfa (9 spp.), and XIII. Saccharina (5 spp.). At the close |

forms. One map shows the distribution of the thirteen sections, and another 
the distribution of the fossil groups. — J. M. C.
