cylindrical pod, has only two paii\sof leaflets with a gland between 

 the lower pair. In C. lUjuatrina (perhaps the most frequently cul- 

 tivated) the five to eight i^airs of leaflets arc narrowly lance-shajjed 

 and very unequal-sided, the petiole bearing a gland just above its 

 base, the pod compressed and niembranaceous. G. occidoUaUs has 

 also a gland at the base of the petiole, five pairs of ovate, lance- 

 shaped leaflets, nearly equal-sided, rough at the edges with minute 

 teeth. h\ C. (data the pod is four-angled, wavy wings traversing 

 the middle of the valves, the petiole triangular and bearing no 

 glands. C. glauca has four to six pairs of leaflets, with a gland 

 between the two lower pairs. C. Jloricla (Public Grounds) is a tree, 

 the petiole bearing no glands, the pods flat, narrow, leathery, 

 about six inches long.
