ESTIVATION 205- 



CASSIA, this odd (posterior) petal is innermost of all in 

 bud, with ERYTHRINA, CROTALARIA, and the others, it 

 is outermost of all, and is much larger than the others. 

 The arrangement of the petals (or any parts) in 

 bud, is termed the aestivation, and into it we will 

 go more fully later on.
