Plant reproductive morphology is asexual, producing only spores. Similarly, flowers produced by the sporophyte may be described as "unisexual" or "bisexual", meaning that they give rise to either one sex of gametophyte or both sexes of gametophyte. The flower is the characteristic structure concerned with sexual reproduction in flowering plants (angiosperms). Flowers vary enormously in their construction (morphology). A "complete" flower, like that of "Ranunculus glaberrimus" shown in the figure, has a calyx of outer sepals and a corolla of inner petals. The sepals and petals together form the perianth. Next inwards there are numerous stamens, which produce pollen grains, each containing a
Surround SCM merging history, changelists, filters, users, groups, labels, etc.). A proxy server can optionally be installed to improve performance of file retrievals for distributed teams. There are several different categories of Surround SCM clients: GUI, CLI, API, Web UI, and plugin. The cross-platform GUI client is developed with Qt and available on Windows, Mac OS X, and Linux. It fully supports all end-user operations and administration operations. The command line interface (CLI) is also available on Windows, Mac OS X, and Linux. The CLI can be used in any command shell or script. Build scripts generally access Surround SCM files via
