Described from excellent pbotographd and a dried flowering branch of the tj-pe 

 and flowers preserved in fluid, lent to Kew by Dr. Marloth, who states ui his- 

 original description that the peduncles are ** non-persistent." This, however, is 

 an error, for they certainly persist for two or more seasons,

 dull dark green, at the upper part. of the main stem separated from
