Pinales
Encyclopedia
The Order Pinales in the Division Pinophyta
, Class Pinopsida
comprises all the extant conifers. This order was formerly known as the Coniferales.
The distinguishing characteristic is the reproductive structure known as a cone
produced by all Pinales. All of the extant conifers, such as cedar, cypress
, fir
, juniper
, larch
, pine
, redwood, spruce
, and yew
are included here. Some fossil
conifers, however, belong to other distinct orders within the Division Pinophyta
.
The yews have previously been separated into a distinct order of their own (Order Taxales
), but genetic evidence indicates that yews are monophyletic with other conifers and they are now included in the Order Pinales. However, the evidence on these facts are vague, therefore it was probably a controversy over time.
The families included are Araucariaceae
, Cephalotaxaceae
, Cupressaceae
, Emporiaceae, Majonicaceae, Pinaceae
, Podocarpaceae
, Sciadopityaceae, Taxaceae
, Taxodiaceae
, Ullmanniaceae, Utrechtiaceae, Voltziaceae.
Pinophyta
The conifers, division Pinophyta, also known as division Coniferophyta or Coniferae, are one of 13 or 14 division level taxa within the Kingdom Plantae. Pinophytes are gymnosperms. They are cone-bearing seed plants with vascular tissue; all extant conifers are woody plants, the great majority being...

Conifer cone
A cone is an organ on plants in the division Pinophyta that contains the reproductive structures. The familiar woody cone is the female cone, which produces seeds. The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity...
