Description: The fossils are petrified ovoid, drupaceous
Among drupaceous fruits cultivated commercially, including peaches, apricots, plums and cherries, researchers have discovered characteristic patterns of development.
The purposes of this paper are (1) to compare the growth of Celtis to other drupaceous fruits; (2) to investigate the biomineralization of modern Celtis fruits and (3) to determine if stable carbon isotope ratios are consistant over the growth of the fruit.
Araliaceae Fruits of this family are commonly drupaceous
, and only rarely winged.
Previous morphological studies have indicated that Styphelieae have the following synapomorphies: fruit drupaceous
, ovary 1-11 locular (each locule containing a single ovule), and the corolla mostly hairy inside (Taaffe et al.
The "Rauvolfieae" of Pichon (1949) (= "Alyxieae" sensu Leeuwenberg, 1994) has traditionally been characterized by having drupaceous
fruits with a stony endocarp.
In contrast, members of Myoporum are characterised by a drupaceous
fruit (Chinnock, 1982b).
