1. =Taxoideæ.= The ovules have either one integument, the external
part of which is fleshy, and the internal hard and stone-like; or two
integuments, of which the external is the fleshy and coloured “aril.”
“Ovuliferous scales” are wanting. The cones are never woody, but are
generally succulent, the bracts become fleshy, or cones usually are not
developed. The seeds project more or less freely beyond the bracts.
2. =Pinoideæ.= The ovules have two integuments, the external one of
which is leaf-like and becomes developed as the “ovuliferous scale”;
if there are several of these in each flower they unite and form a
“symphyllodium.” This may remain free or unite with the bract. The
cones are most frequently woody, rarely succulent. The seeds are hidden
among the cone-scales.
