Foliis in caulem strictum altum sparsis obovatis apiculatis glabris obsolete carinatis, spica longa nuda terminali.
It has a tall erect stem covered with smooth obovate apiculate leaves, and terminated by a leafless spike of flowers, 8 or 9 inches long. They appear to have been crimson, but the dried specimens from which alone they are at present known have only their remains surrounding the fruit.
