Three pines with two needles {Pinussilvatica, P. baltica, P. banksianoides), one kind with five needles(P. cembrifolia), and one fir with plain needles {Picea Engleri), similar tothe P. ajanensis of East Asia, have been described as occurring insuccinite. Concerning the name of the succiniferous trees, it must beremembered that we are often obliged in palaeobotany to label singleorgans of a plant with special names, although some of these maybelong together. Therefore it is necessary to give a peculiar namealso to the pine-wood enclosed in succinite, because it is unknown to. Fig. 2.—Plants included in Amber. A, Flower of Cinnamomum frototypum (after Conwentz Angiospermen des Bern-steins); flower of Pinus Reichiana (after Conwentz Bernsteinbaume). which of the above-mentioned leaves it belongs. Formerly it wascalled Pinites succinifev by Goeppert; however, I have proved in mymonograph that there is no difference between that fossil wood andthe wood of the recent genus Pinus, taken in zi, wider sense, whereforethe proper name should be Pinus succinifera. Those amber forests, of course, did not consist of pines and firsexclusively, but also of Thuja, Biota, Taxodium, and other , there existed a considerable number of other trees, shrubs,and herbaceous plants, which I partly described and figured tenyears ago ( Angiospermen des Bernsteins, mit 13 Tafeln, Danzig,1886). First of all, there are some Monocotyledons, chiefly palms, forinstance, an incomplete male flower of a dat
