An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate). Begonia have an indeterminate inflorescence so are classed as Panicle. Racemose is a type of an inflorescence where the main axis continues to grow indefinitely and does not terminate in flower.
