Paraserianthes lophantha. Elongation of the internodes takes place during plastochron 
seven or eight. In the specimens in cultivation branching was proleptic, and occurred 
only after the terminal bud had been excised. Inflorescences did not form on the 
specimens in cultivation, but on herbarium specimens are pseudoracemes of capitula 
similar in form to the inflorescence of Paraserianthes lophantha. 
Fig. 2. Scanning electron micrographs of Paraserianthes lophantha. a, apical meristem (x 350), 
the leaf-primordium is visible as a bump at 9 o'clock; b, the leaf one plastochron later, the 
arrow shows the differentiating stipules (x 200) partly hidden by a trichome; c, apical region 
(x 100). The numbers 3 and 4 show where the third and fourth leaves were removed, the 
petiole of the fourth leaf encircled nearly half of the circumference of the bud. The arrow 
shows the axillary bud, which has developed in the leaf-axil between the third and fourth 
plastochron; d, dormant axillary buds at an old node.
