Question

Explain about the floral formula.

Answer 1

Floral formula is a means to represent the structure of a flower using numbers, letters and various symbols, presenting substantial information about the flower in a compact form. It can represent particular species, or can be generalized to characterize higher taxa, usually giving ranges of organ numbers. 

Answer 2

Floral formulae were developed at the beginning of the 19th century. The first authors using them were Cassel (1820) and Martius (1828). Grisebach(1854) used them in his textbook to describe characteristics of floral families, stating numbers of different organs separated by commas and highlighting fusion. Sachs (1873) used them together with floral diagrams, he noted their advantage of being composed of "ordinary typeface". Although Eichler widely used floral diagrams in his Blüthendiagramme, he used floral formulae sparingly, mainly for families with simple flowers. Sattler's Organogenesis of Flowers (1973) takes advantage of floral formulae and diagrams to describe the ontogeny of 50 plant species. Newer books containing formulae include Plant Systematics by Judd et al.(2002) and Simpson[11] (2010). Prenner et al. devised an extension of the existing model to broaden the descriptive capability of the formula and argued that formulae should be included in formal taxonomic descriptions. Ronse De Craene (2010) partially utilized their way of writing the formulae in his book. plzzzzzzzzzzzzzzzzzzz keap briliant answer.
