Japanese species

TaxaceaeTorreya

Japanese torreya or Japanese nutmeg-yew (kayanoki in Japanese) is in the yew or Taxaceae family and is native to Japan and South Korea's Jeju Island. It is an evergreen tree growing up to 25 m tall.

  • Evergreen needles are single, alternate, spirally arranged, 2–3 cm long and 3 mm broad, with a sharply-spined tip, spirally arranged but appearing 2-ranked on branches with short petioles twisted to flatten needles in one plane.
  • Species is subdioecious (individual trees producing either mostly male or mostly female cones, but usually with at least some cones of the other sex present). Male cones are small, round, and yellow, 5–6 mm in diameter, in a double row on underside of shoot; female cones are in clusters of 3–8, maturing to a single seed surrounded by a fleshy layer 2 cm long and 1.5 cm broad.
  • Torreya is sometimes mistaken for Cunninghamia lanciolata.
