Abbreviations. Descriptions of floral morphology are largely given in 

 the terms of Floral Formulae, explained under that heading. When 

 the name of a genus or family is repeated in the article dealing with it, 

 it is represented by the initial letter only, e.g. A. for Abies. The 

 name of a family is sometimes abbreviated by the omission of the 

 terminal aceae, &c. ; e.g. Capparid., Compos. The term 'warm' is 

 sometimes used instead of 'tropical and subtropical.' The expression 

 BH. after a genus or family, &c., means "as defined by Bentham and 

 Hooker in their Genera Plantaruni " ; EP. means "as defined by Engler 

 and Prantl in the Pflanzenfamilien and Pflanzenreich"
