French-Belgian- Swiss flora it comes tenth with 147 species. An important biological feature is the preponderance of perennials, which comprise more than two-thirds the number of vascular plants. Among the woody plants are numerous shrubby members of the Chenopocliaceæ, especially of the groups Salsolaceæ and Salicorniecæ. Of the 2878 perennials, 148 species are bulbous and 100 tuberous. There are 64 vascular water-plants, and 115 saprophytic, parasitic and insectivorous species, the last-named including the monotypic endemic genus Drosophyllum. The composition of the flora is as follows:—Central European species, 1638; French (not including Pyrenean), 215; Pyrenean (and not found in the Alps), 188; plants of the Central European Alps and high mountains, 236; Mediterranean, 1132; South Atlantic, 185; North African, 282; plants of Atlantic islands, 16 ; Oriental, 40; Central Asiatic, 8; endemic, 1465; cultivated, &c., 260; making altogether 5660 species.
The second part contains a somewhat exhaustive account of the vegetation of the different botanical districts of the peninsula, namely, the Pyrenean, the North Atlantic, the Central, the Mediterranean, the South Atlantic, and the West Atlantic. The Appendix gives a short account of the alterations which have been produced in the vegetation by cultivation and commerce, from the time of the invasion by the Arabs in the eighth century, bringing several species of corn (Triticum Cevallos Lag., T. fastuosum Lag., and perhaps T. durum Desf.) onwards. It concludes with a list of the plants now cultivated, and also one of those exotic species which have become naturalized and now spread over considerable areas. A notice of this excellent work would be incomplete without a word of praise of the two maps, one illustrating rainfall, the other vegetation-lines ; both are models of clearness.
