 deltoideum like which its flowers are richly spolled with deep purple broken fas- 

 ciae, closely arranged upon a clear green ground. Tlie difference between these 

 iwo species resides in the lip, which in the present is dull green, nearly flat. deeply 

 cordate, iruncate at tbe apex, wiih an obscurely crenated margin, at its base is an 

 elevated yeilow tipped broad tooth, and at its apex an ovate, yellow, flesby, elevated
