Relationship between time since the last fire and flowering in Telopea speciosissima R. Br. and Lambertia formosa Sm

Abstract

For Telopea speciosissima the percentage (or density) of plants in flower, the average number of flowers per inflorescence and the average number of fruits per inflorescence all appear to peak 2 years after a summer fire and decline thereafter. On the other hand, the average height of the inflorescences above the ground increases with time since the last fire. For Lambertia formosa the density of inflorescences appears to reach a peak 2 or 3 years after a summer fire.
