The embryo is inverted or antitropous. ascending; if, on the contrary, it arises a little below the summit, and is directed obliquely downwards, as in the Mezereon (fig. 479) and Apricot, it is suspended ; if from the side of the ovary, without turning upwards or downwards, as in Crassula, it is horizontal or peltate. In some plants, as in Armeria (fig. 440),' the ovule is suspended from the end of a long funiculus arising from the base of the ovary ; such an ovule is frequently termed recUnate. In the above cases the position of the ovule is in general constant, and hence this character is frequently of much impor- tance in distinguishing genera, and even natural orders. Thus, in the Oompositse the solitary ovule is always erect; while in.
