Sciadopitys verticillata, the kōyamaki or Japanese umbrella-pine, is a unique conifer endemic to Japan. It is the sole living member of the family Sciadopityaceae and genus Sciadopitys, a living fossil with no close relatives. The oldest fossils of Sciadopitys are from the Late Cretaceous of Japan, and the genus was widespread in Laurasia during most of the Cenozoic, especially in Europe until the Pliocene. A European relative of this species may have been the primary source of Baltic amber, according to some studies.

The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping. The shoots are dimorphic, with growth divided into long shoots (typically 10–50 cm long) and bearing several buds, and short shoots only 1–2 mm long with only a single bud. The leaves are

This species is closely related to the Kobushi magnolia (Magnolia kobus), Magnolia stellata was accepted as a distinct species in the 1998 monograph by Hunt.

Abies veitchii, also known as Veitch's fir or Veitch's silver-fir, is a species of fir native to Japan from the islands of Honshū and Shikoku. It lives in moist soils in cool wet mountain forests at elevations of 1500–2800 m. It is very shade-tolerant when young, but is not long-lived.
