A mature female big-cone pine (Pinus coulteri) cone, the heaviest pine cone A young female cone on a Norway spruce (Picea abies) Immature male cones of Swiss pine (Pinus cembra) A conifer cone , or in formal botanical usage a strobilus , pl. : strobili , is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads .
Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m (3 to 82 ft) tall, known to reach 40 m (130 ft) at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their ...
The inner bark and resin from the trunk of the tree is reddish. [6] It is usually dioecious, with the male and female cones on separate trees. The male (pollen) cones are oblong, 6 cm (2 + 1 ⁄ 2 in) long at first, expanding to 10–18 cm (4–7 in) long by 15–25 mm (9 ⁄ 16 –1 in) broad at pollen release. Like all conifers it is wind ...

The male cones are slender conic, 5–11 cm (2.0–4.3 in) long and 1–2 cm (0.39–0.79 in) broad and reddish-brown in colour and are lower on the tree than the seed cones. [3] Seedlings appear to be slow-growing [ 3 ] and mature trees are extremely long-lived; some of the older individuals today are estimated to be between 500 and 1,000 ...
Juniper berries are sometimes regarded as arils, [3] like the berry-like cones of yews. Juniperus communis berries vary from 4 millimetres ( 1 ⁄ 8 inch) to 12 millimetres ( 1 ⁄ 2 inch) in diameter; other species are mostly similar in size, though some are larger, notably J. drupacea ( 20–28 mm or 3 ⁄ 4 – 1 + 1 ⁄ 8 in).
The plants are dioecious with pollen cones being solitary while those of female plants hang from a curved, scaly stalk. The seed cones are highly modified, reduced to a central stem 2–3 cm long bearing 1-3 scales, each scale maturing berry-like, oval, about 20 mm long and 10–15 mm broad, red to purple-red with a soft edible pulp covering ...
The trees are mostly dioecious, with male and female cones found on separate trees, [4] though occasional individuals are monoecious or change sex with time. [5] The female cones, usually high on the top of the tree, are globose , and vary in size among species from 7 to 25 centimetres (3 to 10 in) in diameter.
