 The fruiting structure is a stout woody " cone " , with a hairy appearance caused by the persistence of old withered flower parts . Up to 70 woody follicles , each of which contains a single seed , may be embedded in the cone . As with other Banksia species , only a small proportion of flowers go on to form follicles ; in the case of B. telmatiaea , the proportion is around 4 % for those " cones " that set some fruit . However , about 80 % of fruiting structures set no fruit at all . According to John K. Scott , " there [ is ] no obvious reason on the basis of morphology of pollination for this lack of seed set " .
