From [Pine]

...The family Pinaceae consists of 10 genera and 220 species, distributed mainly in the temperate zone of the Northern Hemisphere (Figure). It is divided into three subfamilies: the subfamily Pinus ( Pinus genus), which has long and short branches with scale leaves on the former and needles on the latter; the subfamily Larix ( Larix genus, Pseudolarix genus, Cedrus genus), which has needles on long branches; and the subfamily Abies ( Abies genus, Tsuga genus, Picea genus, Pseudotsuga genus, Keteleeria genus), which has no short branches. The genus Cathaya in Sichuan Province, China, is similar to the genus Pseudotsuga, but it has both short and long branches, making it difficult to determine its affiliation. ...
