Pinales
Monotypic order of conifers comprising only the pine family.
Pinales is a botanical order within the subclass Pinidae, class Pinopsida. Under current taxonomic treatment, it is a monotypic order comprising only one family, the pine family Pinaceae. The name Pinales has historically been used to refer to all conifers, but it was never truly interchangeable with Coniferales—that older name fell out of common use by the mid-20th century.

Lore & Background
In his classification, Gymnospermae was a class of the division Archegoniatae, divided into subclasses including Peucideae (Coniferae). The name Pinales has historically been used to refer to all conifers, but it was never truly interchangeable with Coniferales—that older name fell out of common use by the mid-20th century. Throughout the twentieth century, conifers were generally treated as a single order. Benson divided gymnosperms into three classes: Cycadopsida, Coniferopsida (which included Ginkgo), and Gnetopsida.
Reader's Guide
Pinales holds significance as the order containing the pine family (Pinaceae), which under current taxonomic treatment is the sole family in this monotypic order. The exact phylogeny remains a topic that was 'hotly debated', particularly whether the main lineages are best represented by four subclasses or the more traditional five clades. Pinales, in its current restricted sense, includes only Pinaceae, a practice followed by the Angiosperm Phylogeny Website and the Gymnosperm Database.

Frequently Asked Questions
What is Pinales?
Pinales is a botanical order nested within the subclass Pinidae and the class Pinopsida. Under current taxonomy it is a monotypic order, meaning it contains exactly one family: Pinaceae, the pine family.
Is Pinales the same as 'all conifers'?
No—older literature sometimes used Pinales as a blanket term for every conifer, but that broad usage has been retired. In modern treatment Pinales is a much narrower group, housing only the single pine family.
What happened to the name Coniferales?
Coniferales was the older, catch-all order name for conifers, but it largely fell out of common use by the mid-twentieth century. Pinales, by contrast, is the precise, still-active order name tied specifically to the Pinaceae lineage.
Why does a one-family order matter to conifer fans?
Because Pinaceae includes iconic genera such as Pinus, Picea, Abies, and Larix, Pinales covers an enormous swath of ecological and horticultural diversity. Its monotypic status simply reflects how tightly the pine family clusters on the tree of life, distinguishing it from the broader Cupressales and Araucariales.
