A more recent classification divided the subfamilies and genera based on the consideration of features of ovulate cone anatomy among extant and fossil members of the family. Below is an example of how the morphology has been used to classify Pinaceae.
Christenhusz and colleagues (2011) included only one family in Pinales, Pinaceae, [2] a practice subsequently followed by the Angiosperm Phylogeny Website [33] and the Gymnosperm Database. [35] In this restricted model Pinales (Pinaceae) comprisea 11 genera and about 225 species, all of the other conifers originally included in this order ...
A pine is any conifer tree or shrub in the genus Pinus (/ ˈ p aɪ n ə s /) [2] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.. World Flora Online accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, [3] and Plants of the World Online 126 species-rank taxa (113 species and 13 nothospecies), [4] making it ...
The Laricoideae are a subfamily of the Pinaceae, a Pinophyta division family. They take their name from the genus Larix (), which contains inside most of the species of the group and is one of only two deciduous genera of the pines complex (together with Pseudolarix, which however belongs to a different subfamily, the Abietoideae).
Larix laricina, commonly known as the tamarack, [3] hackmatack, [3] eastern larch, [3] black larch, [3] red larch, [3] or American larch, [3] is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated ...
Stone pine in Brissago, on Lake Maggiore, Switzerland. The stone pine is a coniferous evergreen tree that can exceed 25 metres (80 feet) in height, but 12–20 m (40–65 ft) is more typical.
The longleaf pine (Pinus palustris) is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. [3]
The internal anatomy of both these needle types are identical except for the number of needles in each fascicle suggesting that Little's 1968 designation [7] of this tree as a variety of Pinus edulis is more likely than its subsequent designation as a subspecies of Pinus monophylla based entirely upon its single needle fascicle.
