rous, slender-salverform, the tube 114-2 inches long, the obscurely 5-lobed 
or angulate limb 4-6 lines in diameter, opening only at night and usually 
closing before noon, or under sunshine, filaments slender, equally inserted 
low down on the tube of the corolla: capsule 2-5 lines long, ovate, acute,
