Gymnosperm

There are 794 angiosperm genera, 77% of China's total angiosperm species, 24 gymnosperm, 70 pteridophyte and 102 bryophyte genera. ❋ Unknown (2009)

The receptive part of the gymnosperm ovule is called the micropyle. ❋ Wikipedia (2009)

Vegetation within the desert consists of a thin scrub of Anabasis brevifolia while the peripheral areas support a dwarf woodland dominated by saxaul bush (Haloxylon ammodendron) and the gymnosperm Ephedra przewalskii. ❋ Unknown (2008)

Dominant species include the cold-tolerant, xerophytic shrub, Haloxylon ammodendron (Goosefoot Family Chenopodiaceae), the tamarisk (Reaumuria spp.), and the gymnosperm Ephedra przewalski. ❋ Unknown (2008)

Endemism is particularly high in 33 angiosperm and six gymnosperm, and fern families, most of which are ancient or primitive with restricted relict distributions. ❋ Unknown (2008)

The only gymnosperm tree, Podocarpus (= Nageia) wallichianus, is also endemic. ❋ Unknown (2008)

The relict gymnosperm Welwitschia mirabilis, which represents the sole surviving member of its family, is found throughout the ecoregion. ❋ Unknown (2008)

The distribution of this relict gymnosperm extends from the Kuiseb River in Namibia to Namibe in southern Angola. ❋ Unknown (2008)

The famous relict gymnosperm Welwitschia mirabilis is also found throughout the ecoregion, and it is often the most conspicuous feature of the vegetation, scattered about the arid plains at intervals of 50 to 100 m. ❋ Unknown (2008)

Shady conditions at ground level favor woody climbers that include strangler figs (Ficus spp.) and the cablelike Gnetum, an unusual climbing gymnosperm. ❋ Unknown (2008)

The dry forests have only one gymnosperm and none of these other taxa. ❋ Unknown (2007)

Near the coast the typical dry forests give way to stands of Cycas circinalis, the only gymnosperm typical of the ecoregion. ❋ Unknown (2007)

The gingko is a species of gymnosperm known as a “living fossil,” because it is the only living species in its group. ❋ Unknown (2007)

It explains the inevitable development of gymnosperm into angiosperm by the checked vegetative growth of the ovule-bearing leaf or carpel; while such minor adaptations as the splitting fruit of the geranium or the cupped stigma of the pansy, can be no longer looked upon as achievements of natural selection, but must be regarded as naturally traceable to the vegetative checking of their respective types of leaf organ. ❋ Alfred Russel Wallace (1868)

The observation that a denser ingroup taxon sampling did not have a major effect on tree topology beyond a certain point, but a change in outgroup taxa identity and number did make gymnosperm relationships vary significantly, stimulated us to look at outgroup choice in more detail. ❋ Jose Eduardo De La Torre-Bárcena Et Al. (2009)

The relative placement of gymnosperm groups changes as outgroup taxa are excluded or rooting is forced on certain seed plant taxa. ❋ Jose Eduardo De La Torre-Bárcena Et Al. (2009)

An increase in total characters, but especially an increase in phylogenetically informative characters, would augment both apparent and hidden support in all gymnosperm clades, and provide stronger support for inferences on the hierarchical relationships among the taxa involved. ❋ Jose Eduardo De La Torre-Bárcena Et Al. (2009)

This perspective however is too coarse, as many niche shifts occur within sublineages (including many gymnosperm-angiospem shifts). ❋ Unknown (2009)

It grows cones because it is a gymnosperm (conifer). ❋ Unknown (2008)
