The variety here recognised passes insensibly on the one hand into C. senegalensis 
proper, on the other into (. brocchiana, var. Hartmanni. ‘The original description 
given by Lamarck applies to this variety; the specimen cited by that author belongs, 
however, to the form here described as typical C. senegalensis.
