Podo- carpus has received its name from the fact that the ovule is stipitate, usually arising conspicuously above the bracts (fig. 378). In Saxegothaea (152) the solitary and more or less inverted ovule is borne on the ovuliferous scale near the base of the adaxial face. The ovulate cone of this genus, as stated above, is terminal on the short branch in the axils of whose leaves the stami- nate strobili occur. Its peduncle is at first short and is clothed with bracts that envelop the strobilus, but later it elongates, rises above the bracts, and becomes relatively long and slender. The resemblance of this habit to that described for Podocarpus is evident, although the elongating structure is not the same in the two cases. In both Saxegothaea and Microcachrys there is the same intergrading of bracts into sporophylls above and foliage leaves below that characterizes the araucarians. In Phyllocladus (144) the strobili are borne at the edge of the phylloclads near the base, occurring singly or in pairs, and consisting of six or eight thick bracts, each with an axillary erect ovule. This position is understood when it is remembered that the phylloclad is a transformed dwarf shoot. It is difficult, and perhaps unprofitable, to compare this strobilus situation with that of the Pinaceae; but the two families exhibit the same general features in the position of the ovules, and differ in the compactness of the strobihferous region. It is in this feature that Saxegothaea so impressed Lindley, who established the genus, that he regarded it as a transition form between Taxaceae and Fig. 377.—Torreya taxifolia: ovulat
