The cowjKJJi is ;i very suitable plant as a subject for t^eiittic iinrsti- 

 gjition in the Tropics. It is oa.sy of culture, «tccupies little space, ami 

 usually pnnluces enough seed per })lant foi- a progeny row of ;i hundred 

 or more plants. It comes to maturity in from two to three months, and 

 as it can be s<^)wn almost at any time of year it is by n.. means difficult 

 to study three gem-rations of a cro.ss ammally. The investigations 

 described in this paper deal with the iidieiitance ..f taeiois r(.ncenied in 

 the production of the following charact* is : 

 I. The colour <'>f the flower. 



II. The pattern of the .seed coat. 



III. The C(»lour of the pntt«-rn of the see(| coat.
