 sometimes three with a purple spot at base.

The Partridge-Pea changes the position of its leaf- 

 lets at night, and also by day when roughly treated. 

 The ten or more pairs of leaflets slowly turn their 

 outer edges uppermost after sunset. The flowers are 

 a brilliant yellow, large, but only four of the petals 

 expand fully.
