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. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like.
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 ...
Kahikatea is a coniferous tree reaching a height of 50–65 m (164–213 ft), making it the tallest New Zealand tree, [3] with a trunk 1–2 m (3.3–6.6 ft) through. It has a 600 year life span and gains maturity after between 250 and 450 years. [4] Near the base of the tree, the roots are typically buttressed and grooved.
The seed cones are highly modified, reduced to a central stem 1–5 cm long bearing several scales; one to five scales are fertile, each bearing a single seed surrounded by fleshy scale tissue, resembling a drupe. These berry-like cone scales are eaten by birds which then disperse the seeds in their droppings.
The order Pinales in the division Pinophyta, class Pinopsida, comprises all the extant conifers. The distinguishing characteristic is the reproductive structure known as a cone produced by all Pinales. All of the extant conifers, such as Araucaria, cedar, celery-pine, cypress, fir, juniper, kauri, larch, pine, redwood, spruce, and yew, are ...
Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae.Coulter pine is an evergreen conifer that lives up to 100 years. [2] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico, occurring in mediterranean climates, where winter rains are infrequent and summers are dry with ...
Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California.It is notable for having the largest (by far) cones in the genus Pseudotsuga, hence the name.
The pine siskin in its typical morph is a drab bird, whereas the Eurasian siskin (a bird the species does not naturally co-exist with), in many plumages, is much brighter. Adult male Eurasian siskins are bright green and yellow with a black cap, and an unstreaked throat and breast; the pine siskin does not have a corresponding bright plumage.
