differs from Tacsonia by the calyx being only five-cleft, and the want of bracteas ; from Passiflora, by the 

 tube of the calyx being as long as the segments ; from Murucuja, by the structure of the corona ; but it is 

 perhaps nearest this last.

Hab. Talisco. — This, having large bracteas, and a five-cleft calyx, differs from all other species which we

 being Smith's plant.

The habit of our plant resembles E. panieutatum and E. aguaticum, but some of the leaflets of the involu- 

 crum are toothed, and the teeth of the leaves are in pairs. The capitula are nearly globose.
