Has. Jambrasbamba, Andes of Peru. Mathews (n. 1317). 
This has the largest flowers of any species of Lisianthus with 
which I am acquainted, and will, with many other new species, 
be more fully described in a Memoir on the Gentianee, now 
in the press, by Dr. Grisebach. This plant turns almost black 
in drying.
