Ripe seeds of Torreya taxifolia †Torreya clarnensis has been described from Middle Eocene fossils found in the Clarno Formation of Central Oregon, United States. [10] Leafy branch fossils of †Torreya bilinica are known from Oligocene strata of Zichov near Bílina, Czech Republic, early Miocene deposits of Güvem central Anatolia, Turkey and late Miocene deposits of Spain.
In 2015 Shoal Sanctuary in Florida guided children from nearby scout and church groups to plant torreya seeds into steephead and other ravines onsite. [198] Children were encouraged to name each of their seeds. In 2019 Torreya Guardians posted a 2-part video of the young seedlings. [199]
Torreya species are all adapted to establish and grow slowly as subcanopy woody plants in forest habitats of moderate to dense shade. In this way, their leaf structure and growth habit resemble species of yew, genus Taxus, which is a close relative. [8] Torreya species are found in late seral and climax communities. Owing to their ability to ...
Torreya grandis (Chinese: 香榧; pinyin: xiāngfěi; lit. 'fragrant nutmeg yew') is a species of conifer in either the family Taxaceae, or Cephalotaxaceae.Common names include Chinese Torreya and Chinese nutmeg yew, [2] which refers to its edible seeds that resemble nutmeg and to its yew-like foliage, although it is not related to either nutmeg nor to the true yews belonging to the genus Taxus.
Like most pine tree species, the seeds have a wing attached to them, but in this species it is papery, breaks off easily, and is entirely non-functional, so this tree is entirely reliant upon animals to disperse its seeds. The scrub jay (Aphelocoma californica) is the most important species when it comes to dispersal of the seeds (on the ...
Torreya Guardians was then described as having "established private experimental populations on the property of cooperative landowners to help preserve the species outside of its historic range because of its decline, lack of federal funding, and the availability of privately owned and commercially available plants and seeds."
Torreya nucifera is a slow-growing, ... maturing in 18–20 months to a single seed surrounded by a fleshy layer, 2 cm long and 1.5 cm broad.
The plants are monoecious, subdioecious, or dioecious. The male cones are 4–25 mm long, and shed pollen in the early spring. The female cones are reduced, with one to a few ovuliferous scales, and one seed on each ovuliferous scale. As the seed matures, the ovuliferous scale develops into a fleshy aril fully enclosing the seed. The mature ...
