lyginopteridales การใช้

Nowadays, four orders of Palaeozoic seed plants tend to be referred to as pteridosperms : Lyginopteridales, Medullosales, Callistophytales and Peltaspermales.
Most evidence of the Lyginopteridales suggests that they grew in tropical latitudes of the time, in North America, Europe and China.
However, later in Middle Pennsylvanian times the Lyginopteridales went into serious decline, probably being out-competed by the Callistophytales that occupied similar ecological niches but had more sophisticated reproductive strategies.
The Lyginopteridales became the most abundant group of pteridosperms during Pennsylvanian times the Medullosales took over as the more important of the larger pteridosperms but the Lyginopteridales continued to flourish as climbing ( lianesent ) and scrambling plants.
