 Wikipedia: Taxales
The Order Taxales was once treated as a distinct order in the Division Pinophyta, Class Pinopsida, and included only those species of plants in the Family Taxaceae known commonly as yews.
Recent genetic and micromorphological studies have shown, however, that the Taxaceae are closely related to the other conifers, particularly to those genera classified in the Family Cephalotaxaceae, and the Order Taxales is no longer recognised as distinct — the Family Taxaceae is now included in the Pinales.

The Order Taxales in the Division Pinophyta, Class Pinopsida includes the yews.
Some botanists do not recognize this order, considering the Taxaceae to belong in the Pinales.
The distinguishing characteristic is the absence of seed cones in the Taxales.

The microspores, or pollen grains, are produced in such vast abundance that clouds of pollen, carried on the wind, have settled on ships far at sea.
In plants of the order Taxales (yews) the seeds, produced individually on short shoots, are surrounded by a conspicuous, fleshy covering.
The class Ginkgoopsida contains the contains the ginkgo, Ginkgo biloba, the last surviving species of a once large and flourishing group of gymnosperms.

For about six or seven months after the flowers appear, the fruit begins to grow: it is a deep crimson when ripe and contains two seeds, the coffee beans.
The two orders of conifers are Pinales and Taxales.
The seeds are formed on the scales of the female cones and the pollen is produced in separate male cones (as opposed to carpels and anthers).

 Pinophyta description   (Site not responding. Last check: 2007-10-08)
Some authors segregate the yews and plum-yews (Taxaceae and Cephalotaxaceae) as Order Taxales, and there is general agreement that they warrant distinction above the rank of family.
Some authors segregate the family Cupressaceae into two families, Cupressaceae and Taxodiaceae; see Cupressaceae for relevant remarks.
Except for 20 species in the order Taxales (which some taxonomists call the family Taxaceae in the Coniferales), they include all of the conifers.

 Non-wood forest products from conifers - INTRODUCTION   (Site not responding. Last check: 2007-10-08)
The objective of this paper is to provide a global review of the non-wood uses of conifers.
For the purposes of this paper, conifers are defined as trees and shrubs of the botanical orders Coniferales, Taxales and Ginkgoales (Rushforth 1987).
Although some services are briefly mentioned, the focus of this paper is on products which conifers provide species, which are important sources of non-wood forest products, and places where these products are harvested.

Subdivision of the living conifers into two or more orders has been proposed from time to time.
The most commonly seen in the past was a split into two orders, Taxales (Taxaceae only) and Pinales (the rest), but recent research into DNA sequences suggests that this interpretation leaves the Pinales without Taxales as paraphyletic, and the latter order is no longer regarded as distinct.
Derived from papers by A. Farjon and C. Quinn & R. Price in the Proceedings of the Fourth International Conifer Conference, Acta Horticulturae 615 (2003)]]The conifers are now accepted as comprising six to eight families, with a total of 65-70 genera and 600-650 species.

Pinopsida is the only class in the Coniferophyta Division, so the description above applies to the Class as well as the Divsion.
The Pinopsida Class is split into two Orders, the Pinales Order and the Taxales Order.
This Order contains the majority of plants in the Pinopsida Class; including pines, cedars, hemlocks, cypress, juniper, larches, firs, and spruces.

ANALYZING THE REPRODUCTIVE BIOLOGY OF TAXUS: SHOULD IT BE INCLUDED IN Authors:
Separation of Taxus and allied genera of Taxaceae as the order Taxales seems unjustified.
The authors summarise a theory explaining the evolution of the ovulate structure including a primary and secondary shoot, and believe that this helps to explain many of the unusual morphological features found in Taxus.
