WebThe lycophyte genus Selaginella alone constitutes the family Selaginellaceae, the largest of the lycophyte families. The genus is estimated to contain 700-800 species … WebBoth of the latter two families have only one genus each— Selaginella with about 700 species and Isoetes with about 100. None of the lycophytes is over a meter or so tall, even in the tropics where they flourish and are the most abundant. Many are epiphytes growing high in the tree crowns.
