 lanceolatis haud reticulatis, Corollae subrotatae tubus bre- 

 vissimus prope basim zona purpurea notatus, lobi inaequales 

 bis terve longiores, Stamina 3-4 cum alius rudimento. Cap-

 Rhizome very short, fibrillose. Leaves alternate, sessile, 

 semiamplexicaul, 3-4^°Xio-i5\ oblique, obtuse, membrana-
