  Pinophyta
Pinophyta is one of 13 or 14 division level taxa within the Kingdom Plantae.
In a broader sense, the Pinophyta would be equivalent to the gymnosperms, although such a grouping is clearly polyphyletic, with the latter including distinct groups like the Cycadales that are excluded from the Pinophyta.
In the more modern, narrower sense, Pinophyta is equivalent to the former Coniferales: cone-bearing, seed plants with vascular tissue, typified by trees such as firs and most pines, or shrubs such as many junipers and a few pines.

 Pinophyta
The conifers, division '''Pinophyta''', are one of 13 or 14 division level taxa within the Kingdom Plantae.
They are cone -bearing seed plant s with vascular tissue; all extant conifers are woody plant s, the great majority being tree s with just a few being shrub s.
The division name Pinophyta conforms with the rules of the '' ICBN '', which state (Art 16.1) that the names of higher taxa in plants (above the rank of family) are either formed from the name of an included family, in this case Pinaceae (the pine family), or are descriptive.

 Pinophyta - CreationWiki
Pinophyta is a division of the gymnosperms, which along with all other land plants were formed on the third day of creation.
The plants in Pinophyta are conifers, meaning they bear cones.
As with other plants Pinophyta seeds are dispersed by birds, or small mammals.

 Pinophyta - Biocrawler   (Site not responding. Last check: 2007-11-02)
The current division name Pinophyta derives from the rules of taxonomic nomenclature, which require that the names of higher taxa in plants are based on the name of the type genus, in this case, Pinus (pines).
In an older, broader sense of the name, the conifers were often considered equivalent to the Gymnosperms, although this grouping is polyphyletic as it includes distinct, only distantly related plants like the cycads and ginkgos not in the Pinophyta, but excludes the Magnoliophyta (flowering plants), equally or perhaps more closely related.
The most commonly seen in the past was a split into two orders, Taxales (Taxaceae only) and Pinales (the rest), but recent genetic evidence has shown that this interpretation leaves the Pinales without Taxales as polyphyletic, and the latter order is no longer regarded as distinct.

 Pinophyta Index
Ovules are produced naked on the adaxial (toward the main axis) surface of cone scales.
The Division Pinophyta differs from flowering plant division (Magnoliophyta) in that there is no container or ovary surrounding the ovules and thus produces no true fruit (fruits are matured ovaries).
Pollination occurs by wind transfer of the pollen from pollen producing cones to the seed cones.

 Pinophyta description
The Pinophyta has been subdivided along a variety of different lines and the recent flood of information on fundamental taxonomic characters (such as chloroplast DNA) has led to further revisions.
The next group is the Pinophyta or Gymnospermae, which are the focus of this presentation.
See also the references list for a fairly extensive (and growing) list of sometimes-annotated citations, and White 1994 for a beautifully illustrated account of the fossil origins of the major gymnosperm and angiosperm groups.
