drupaceous

(2010) found that most seeds were small sized and came from berry or drupaceous fruits with many seeds.

Several features common in Apiineae are also found in most of these groups, such as ovary-roof nectaries (Erbar & Leins, 2010), a single functional ovule (either per locule or per ovary), drupaceous fruits, and sheathing petiole bases, but there are significant exceptions to each.

americanus are drupes containing an indurate endocarp (Green 1958), and vascular strands within the pericarp are located in the outer portions of the endocarp adjacent to the mesocarp (Figures 6 and 7), a location identical to that of Olea europaea L., another drupaceous species in the Oleaceae (Hanausek 1907; King 1938).

These three genera share strong synapomorphies such as expanded and deeply lobed stigma, small corolla, drupaceous fruit and wind pollination.

Acerola has drupaceous fruits with a soft yellow and acid pulp, and three imbricate flattened seeds.

The drupaceous pistachio fruit consists of an edible kernel (seed) and a seed coat (testa) encased in a hardened shell (endocarp), all of which are surrounded by a fleshy hull (mesocarp and epicarp) which is removed during processing [24].

Species of Didymaea are characterized by their procumbent or climbing stems, opposite leaves with ovate, oblong-ovate, lanceolate, elliptic, or rarely linear blades, small, shallowly to deeply bilobed or geminate interpetiolar stipules, axillary inflorescences with small, bisexual homostylous flowers with calyces reduced or absent, small, white to purple corollas with short tubes and 4-valvate lobes, 4 stamens with dorsifixed anthers, 2-locular ovaries with one axillary ovule per locule, and black, drupaceous fruits that are dimidiate and deeply bisulcate or sometimes subglobose.
