psilotaceae การใช้

• All Psilotaceae share a few characteristics.
• The genus " Bernhardia " ( family Psilotaceae ) is named in his honor.
• As circumscribed by Smith " et al . ", 2006, Psilotopsida contains two families, Psilotaceae and Ophioglossaceae, placed in orders Psilotales and Ophioglossales, respectively.
• Prior to that, most of the early polysporangiophytes had been placed in a single Psilotaceae, the whisk-ferns, were sometimes added to the class, which was then usually called Psilopsida.
• The class should not be confused with the current use of the name Psilotopsida, which refers to a class of living ferns, containing only Psilotaceae ( whisk-ferns ) and Ophioglossaceae ( moon-worts and adder's-tongue ferns ).
• "' Ophioglossaceae "', the adder's-tongue family, is a family of ferns ( though some studies have instead suggested a closer relationship to angiosperms ), currently thought to be most closely related to Psilotaceae, the two together comprising the class Psilotopsida as the sibling group to the rest of the ferns.
