The cones are broad, ovoid, 8–15 cm (3–6 in) long, and take 36 months to mature, longer than any other pine. The seeds ( pine nuts , piñones , pinhões , pinoli , or pignons ) are large, 2 cm ( 3 ⁄ 4 in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 4–8 mm ( 5 ⁄ 32 – 5 ⁄ 16 in ...
Composed of a large bronze pine cone almost four meters high which once spouted water from the top, the Pigna originally stood near the Pantheon next to the Temple of Isis. It was moved to the courtyard of the Old St. Peter's Basilica during the Middle Ages and then moved again, in 1608, to its present location. [1]
A mature female big-cone pine (Pinus coulteri) cone, the heaviest pine cone A young female or seed cone on a Norway spruce (Picea abies) Immature male or pollen 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.
The name means "pine cone" in Italian, and the symbol of the rione is the colossal bronze pine cone standing in the middle of the homonymous fountain. The fountain, which was initially located in the Baths of Agrippa , now decorates a vast niche in the wall of the Vatican facing the Cortile della Pigna , located in Vatican City .
Subfamily Pinoideae : cones are biennial, rarely triennial, with each year's scale-growth distinct, forming an umbo on each scale, the cone scale base is broad, concealing the seeds fully from abaxial (below the phloem vessels) view, the seed is without resin vesicles, the seed wing holds the seed in a pair of claws, leaves have primary ...
The cones have 10–14 scales, which are green at first and mature to brown about 20–24 months after pollination. The male cones are 3–5 mm long and release highly allergenic pollen in late winter. The cones of C. sempervirens can withstand years of being sealed and are known to perform serotiny. [8]
Antinous holding the thyrsus while posed as Dionysus (Museo Pio-Clementino). In Ancient Greece a thyrsus (/ ˈ θ ɜː r s ə s /) or thyrsos (/ ˈ θ ɜːr s ɒ s /; Ancient Greek: θύρσος) was a wand or staff of giant fennel (Ferula communis) covered with ivy vines and leaves, sometimes wound with taeniae and topped with a pine cone, artichoke, fennel, or by a bunch of vine-leaves and ...
The female cone then opens, releasing the seeds which grow to a young seedling. To fertilize the ovum, the male cone releases pollen that is carried in the wind to the female cone. This is pollination. (Male and female cones usually occur on the same plant.) The pollen fertilizes the female gamete (located in the female cone).
