it bears a considerable resemblance. The only objection to the 

 arrangement is the somewhat proportionately large and prominent 

 sepals ; but the flower is scarcely calycine, and the same difficulty 

 meets us constantly in endeavouring to define rigidly the boundaries

A distinct species, not much like any other known to me. In 

 habit and leaves it bears a great resemblance to Sorocephalus 

 salsoloides B. Br.
