Male cones of a pine

A 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 female cone, which produces seeds. The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity. The name "cone" derives from the fact that the shape in some species resembles a geometric cone. The individual plates of a cone are known as scales.

The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to species. Extending out from a central axis are microsporophylls (modified leaves). Under each microsporophyll is one or several microsporangia (pollen sacs). The photo (right) shows mature male pine cones shortly after pollen release. A sporangium (pl. ...

The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules within which, when fertilized by pollen, become seeds. The female cone structure varies more markedly between the different conifer families, and is often crucial for the identification of many species of conifers, in as much as seeing the foliage alone may be insufficient to differentiate between closely related species.

The members of the pine family (pines, spruces, firs, cedars, larches, etc.) have cones that are imbricate with scales overlapping each other like fish scales. These are the "archetypal" cones. The scales are spirally arranged in fibonacci number ratios.

The female cone has two types of scale: the bract scales, derived from a modified leaf, and the seed scales (or ovuliferous scales), one subtending each bract scale, derived from a highly modified branchlet. On the upper-side base of each seed scale are two ovules that develop into seeds after fertilisation by pollen grains. The bract scales develop first, and are conspicuous at the time of pollination; the seed scales develop later to enclose and protect the seeds, with the bract scales often not growing further. The scales open temporarily to receive pollen, then close during fertilisation and maturation, and then re-open again at maturity to allow the seed to escape. Maturation takes 6-8 months from pollination in most Pinaceae genera, but 12 months in cedars and 18-24 months (rarely more) in most pines. The cones open either by the seed scales flexing back when they dry out, or (in firs, cedars and golden larch) by the cones disintegrating with the seed scales falling off. The cones are conic, cylindrical or ovoid (egg-shaped), and small to very large, from 2-60 cm long and 1-20 cm broad. Binomial name Pseudolarix amabilis (Nelson) Rehder Pseudolarix is a monotypic genus in the family Pinaceae. ... This article is about the geometric object, for other uses see Cone. ...

An oval or ovoid was originally an egg shape (from Latin OVVM); it is now usually used to refer to ellipses, but can also mean any similar shape, such as egg shapes or race-course shapes (a semicircle on either side of a quadrilateral). ...


Araucariaceae cones

Members of the Araucariaceae (Araucaria, Agathis, Wollemia) have the bract and seed scales fully fused, and have only one ovule on each scale. The cones are spherical or nearly so, and large to very large, 5-30 cm diameter, and mature in 18 months; at maturity, they disintegrate to release the seeds. In Agathis, the seeds are winged and separate readily from the seed scale, but in the other two genera, the seed is wingless and fused to the scale. Genera Agathis Araucaria Wollemia The Araucariaceae are a very ancient family of conifers. ... Species See text. ...

Podocarpaceae cones

Berry-like Podocarpus cone
Berry-like Podocarpus cone

The cones of the Podocarpaceae are similar in function, though not in development, to those of the Taxaceae (q.v. below), being berry-like with the scales highly modified, evolved to attract birds into dispersing the seeds. In most of the genera, two to ten or more scales are fused together into a usually swollen, brightly coloured, soft, edible fleshy aril. Usually only one or two scales at the apex of the cone are fertile, each bearing a single wingless seed, but in Saxegothaea several scales may be fertile. The fleshy scale complex is 0.5-3 cm long, and the seeds 4-10 mm long. In some genera (e.g. Prumnopitys), the scales are minute and not fleshy, but the seed coat develops a fleshy layer instead, the cone having the appearance of one to three small plums on a central stem. The seeds have a hard coat evolved to resist digestion in the bird's stomach, and is passed in the bird's droppings.

Juniper "berries", which are used to flavor gin, are actually modified cones.

Members of the cypress family (cypresses, arborvitae, junipers, redwoods, etc) differ in that the bract and seed scales are fully fused, with the bract visible as no more than a small lump or spine on the scale. The botanical term galbulus (plural galbuli; from the Latin for a cypress cone) is sometimes used instead of strobilus for members of this family. The female cones have one to 20 ovules on each scale. They often have peltate scales, as opposed to the imbricate cones described above, though some have imbricate scales. The cones are usually small, 0.3-6 cm long, and often spherical or nearly so, like those of Nootka Cypress, while others, such as Western Redcedar, are narrow. The scales are arranged either spirally, or in decussate whorls of two (opposite pairs) or three, rarely four. The genera with spiral scale arrangement were often treated in a separate family (Taxodiaceae) in the past. In most of the genera, the cones are woody and the seeds have two narrow wings (one along each side of the seed), but in three genera (Platycladus, Microbiota and Juniperus), the seeds are wingless, and in Juniperus, the cones are fleshy and berry-like.

Taxaceae and Cephalotaxaceae cones

Berry-like yew cone
Berry-like yew cone

Members of the yew family and the closely related Cephalotaxaceae have the most highly modified cones of any conifer. There is only one scale in the female cone, with a single poisonous ovule. The scale develops into a soft, brightly coloured sweet, juicy, berry-like aril which partly encloses the deadly seed. The seed alone is poisonous. The whole 'berry' with the seed is eaten by birds, which digest the sugar-rich scale and pass the hard seed undamaged in their droppings, so dispersing the seed far from the parent plant.

Location and distribution

For most species, male and female cones occur on the same plant (tree or shrub), with female usually on the higher branches towards the top of the plant. This distribution is thought to improve chances of cross-fertilization, as pollen is unlikely to be blown vertically upward within the crown of one plant, but can drift slowly upward in the wind, blowing from low on one plant to higher on another plant. In some conifers, male cones additionally often grow clustered in large numbers together, while female cones are more often produced singly or in only small clusters.

Dozens of male cones (orange and flower-like) occur in a cluster; the female cone is still immature (olive green). Lodgepole Pine.

A further characteristic arrangement of pines is that the male cones are located at the base of the branch, while the female at the tip (of the same or a different branchlet). However, in larches and cedars, both types of cones are always at the tips of short shoots, while both sexes of fir cones are always from side buds, never terminal. There's also some diversity in bearing in Cupressaceae. Some, Cupressus for instance, has little or no differentiation in the positions of male and female cones.

Trivia

  • The Norwegian municipality of Drangedal has two pine cones in its coat-of-arms.
  • Because of their unique mass distribution and aerodynamical qualities, pine cones are often used as rudimentary play objects, such as in pine cone golf. Small children are also known to wedge twigs and brush between the scales of a pine cone to imitate animals, such as the cone cow.
