1997) and some Cupressaceae
, (Chamaecyparis--Owens et al.
The other family, Cupressaceae
, is represented by four genera, four specific and two infraspecific taxa.
Leaves scale-like or needle-like; leaf arrangement opposite or whorled, not in fascicles; seed cones fleshy and small (up to 1 cm long) Cupressaceae

This range of cone and ovule morphology within the family, progressing toward the Podocarpus condition, shows a parallel to cone reduction in the Cupressaceae
and Taxodiaceae (cf.
The component plants of this group included the fossil examples of Araucariaceae, Podocarpaceae, Cupressaceae
, Akania (Akaniaceae), Casuarinaceae, Nothofagus (Nothofagaceae) and Eucalyptus (Myrtaceae) discussed by Hill and Carpenter (1991).

Other conifer taxa include Abies, Larix, Pinus, Tsuga, and Cupressaceae
(all less than 5%).
Both desiccation and heat are necessary for seed dispersal from serotinous cones of some members of the Pinaceae and Cupressaceae
(Teich, 1970; Vogl et al.
Affinities of modern taxa relative to one another are inferred from these studies, and important strides have been made in assessing the interrelationships of the Cupressaceae
, Sciadopityaceae, and Taxodiaceae.
Fleshy animal-dispersed cones are present in all five species of North American Taxaceae and all 13 species of Juniperus (Cupressaceae
), but are absent in the remaining Cupressaceae
(8 genera, 17 species) and in the North American Pinaceae (6 genera, 64 species) (Givnish, 1980; Adams, 1993).
Some palynological observations of Taxaceae, Cupressaceae
The same applies to ruminate storage tissues of gymnospermous seeds, as reported for Araucariaceae (Coulter & Chamberlain, 1910), Gnetaceae (Schnarf, 1933), Phyllocladaceae (Coulter & Chamberlain, 1910), Taxaceae (Oliver, 1902; Coulter & Land, 1905; Lotsy, 1911), and, less pronounced, Cupressaceae
, Ephedraceae, and Cephalotaxaceae (Tamamshjan, 1951).
