asteroxylon meaning in Hindi

Examples

1. The fragments were considered to be parts of " Asteroxylon mackiei ".
2. It is more derived than the coexisting genus " Asteroxylon ", which has enations lacking vascules, in contrast to the true leaves of " Drepanophycus ".
3. In 1964 Lyon described sporangia belonging to " Asteroxylon mackiei " and suggested that Kidston and Lang's specimens were a new species which he called " Nothia aphylla ".
4. "Asteroxylon " differs from other similar Early Devonian lycopsids such as " Drepanophycus " and " Baragwanathia " in that the singular vascular leaf trace in these latter plants extends into the leaf.
5. Though the rhyniophytes are well represented, plants with simpler anatomy, like " Aglaophyton ", are also common; there are also more complex plants, like " Asteroxylon ", which has a very early form of leaves.
6. The presence of soft tissue, including parenchyma, is not observed elsewhere in the fossil record The analysis of rhizomes and rhizoids makes it possible to discern which plants had an active water uptake system ( e . g . " Horneophyton " ), and which were likely to have colonised waterlogged surfaces ( " Asteroxylon " ).
7. ""'Asteroxylon " "'( " star-shaped xylem " ) is an extinct genus of vascular plants of the Division Lycopodiophyta known from anatomically preserved specimens described from the famous Early Devonian Rhynie chert and Windyfield chert in Aberdeenshire, Scotland . " Asteroxylon " is considered the most basal member of the Lycopsida.

9. The species is known only from the Rhynie chert in Aberdeenshire, Scotland, where it grew in the vicinity of a silica-rich hot spring, together with a number of associated vascular plants such as a smaller species " Rhynia gwynne-vaughanii " which may be interpreted as a representative of the ancestors of modern vascular plants and " Asteroxylon mackei ", which was an ancestor of modern clubmosses ( Lycopsida ).
