Home > Cephalotaxaceae

The Family Cepahlotaxaceae is a small grouping of conifers, with three genera and about 20 species, closely allied to the Taxaceae, and included in that family by some botanists. They are restricted to east Asia, except for two species of Torreya found in the southwest and southeast of the USA; fossil evidence shows a much wider prehistorical northern hemisphere distribution. The differences between the two families are as follows:

* To 25 mm in Austrotaxus

These are much branched, small trees and shrubs. The leaves are evergreen, spirally arranged, often twisted at the base to appear 2-ranked. They are linear to lanceolate, and have pale green or white stomatal bands on the undersides.

The male conesA cone (in formal botanical usage: strobilus plural strobili) is an organ on plants in the division Pinophyta ( conifers) that contains the reproductive structures. The familiar woody cone is the seed-producing female cone. The male cones, which produces are 4-25 mm long, and shed pollenSEM image of pollen grains from a variety of common plants: sunflower Helianthus annuus , morning glory Ipomea purpurea ,hollyhock Sildalcea malviflora , lily Lilium auratum , primrose Oenothera fruticosa , and castor bean Ricinus communis . Pollen is a f 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 arilAn aril is a fleshy covering of certain seeds formed from the funiculus (attachment point of the seed). The aril creates a fruit-like structure (called a false-fruit and is produced by a few species of gymnosperms, notably the yews of the Family Taxaceae. fully enclosing the seed. The mature aril is thin, green, purple or red, soft and resinous. Each ovuliferous scale remains discrete, so the cone develops into a short stem with one to a few berryThis article is about the fruit. For other meanings, please see Berry (disambiguation). In botany, a berry is the most common type of simple fleshy fruit one in which the entire ovary wall ripens into an edible pericarp . The ovary is always superior in t-like seeds.
