184. Staphylea L. 



Inconspicuous, homogamous flowers associated in racemose inflorescences ; 

 nectar half concealed, secreted at the base of the ovary. 



615. S. pinnata L. (Kirchner, 'Flora v. Stuttgart,' p. 356; Knuth, 'Bloemen- 

 biol. Bijdragen.') — According to Kirchner, the sepals — which are white, usually 

 tinged with red externally — spread out till in the end they are almost horizontal. 

 The five small white petals are placed vertically in the pendulous flower, and sur- 

 round the five stamens pretty closely. The cup-shaped green receptacle forms a 

 groove round the base of the ovary, bounded externally by a pentagonal 

 ridge, outside which the stamens are inserted. The approximated stigmas of the 

 two styles are fused together. They are matured simultaneously with the anthers.
