This is a tree 80 or 40 feet high, from the woods near 
Guaduas in the province of Bogota, found at an elevation of 
4,000 feet, and known under the name of Ariza. The flowers 
are produced at the points of the shoots, and taken in one mass 
in a perfect specimen, are five to six inches across, of the 
richest scarlet, and continue to unfoid for several weeks in 
succession. A few plants have been raised in the garden of 
the Horticultural Society of London, from seeds brought home 
by Mr. Hartweg.
