In the classification of Vogel (1980), it was adopted the type Macaranga for seedlings of Serjania communis, which consist of phanerocotylar and epigeal seedlings, and foliaceous cotyledons.

Seeds with epigeal emergence, such as soybeans, where the cotyledons emerge aboveground, are more subject to crusting of the soil surface than seeds of plants such as grasses that have hypogeal emergence.
Whereas Asiatic lily seed is epigeal (putting up a leaf above ground right away and then forming the bulblet), seeds of martagons and some other species germinate in a hypogeal manner.

Greenslade, 1964; Luff, 1975; Southwood, 1978; Halsall and Wratten, 1988), pitfall traps continue to be used in ecological studies of epigeal arthropods such as carabids, because the traps are inexpensive and require a minimum amount of labor (Halsall and Wratten, 1988).
Although this termite is a pest of wood in service, its epigeal foraging behavior and arboreal nesting habits allow for easy detection (Scheffrahn et al.
