zosterophyllopsida造句

• "Nothia " has been placed in the group initially established by Banks as the subdivision Zosterophyllophytina or the class Zosterophyllopsida.
• It falls outside the core clade of zosterophylls ( Zosterophyllopsida sensu Kenrick & Crane ), whose members have sporangia arranged in two rows and new growths with coiled tips.
• The class Zosterophyllopsida sensu Kenrick & Crane may be restricted to this core clade, leaving many genera ( e . g . " Hicklingia ", " Nothia " ) with no systematic placement other than Lycophytina sensu Kenrick & Crane, but nevertheless still informally called " zosterophylls ".
