A strobilus (pl.: strobili) is a structure present on many land plant species consisting of sporangia -bearing structures densely aggregated along a stem. Strobili are often called cones, but some botanists restrict the use of the term cone to the woody seed strobili of conifers.

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.

Conifer - Strobili, Pollination, Cone: In all conifers the organs containing microsporangia (“male”) are separate from those bearing megasporangia (“female”). Wide variations in the female (megasporangiate) reproductive structures among the conifers …

We may easily recognize the female strobili of pine, but people often mistake the fruit of some species like juniper and yew for berries. The fleshy seed cone of cypresses (and sometimes junipers) is also called a galbulus.

Some sporophylls are arranged in cone structures called strobili. The seedless vascular plants include club mosses, which are the most primitive; whisk ferns, which lost leaves and roots by reductive evolution; and horsetails and ferns.

1993年6月9日 · Flowers of the conifers (pine, spruce, fir, and other cone-bearing woody plants) are called strobili, which means small cones. They do not have a calyx, corolla, stamens, or pistils as many flowers do. The strobili consist of a central …

The meaning of STROBILUS is an aggregation of sporophylls resembling a cone (as in the club mosses and horsetails).

Early pollen cones (microsporangiate strobili) were simple structures consisting of an axis with modified leaves (microsporophylls) that bore microsporangia. From: Trends in Plant Science, 1998

Strobili often play a role in the dispersal of seeds; once mature, female strobili open to release seeds into the environment. The structure and arrangement of strobili can provide important taxonomic clues for identifying different species within the gymnosperm group.

2015年11月23日 · Pinecones, mature fronds of ferns, and flowers are all sporophylls —leaves that were modified structurally to bear sporangia. Strobili are structures that contain the sporangia. They are prominent in conifers and are known commonly …
