differs from Tacsonia by the calyx being only five-eleft, 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 
know, and even from all the sections of the genus proposed by De Candolle. We have little doubt of its 
being Smith’s plant.

The habit of our plant resembles iJ. paniculatum and E. aquaticum, 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.
