The variety here recognised passes insensibly on the one hand into C. senegalensis 

 proper, on the other into C. brocchiana, \Bt.v. Hartmanni. The original des<;ription 

 given by Lamarck applies to this variety ; the specimen cited by that author belongs, 

 however, to the form here described as typical C. senegalenHs.
