This species has come to light again from Jocold and 
Chacon. The flowers, about five in number, are borne in 
fascicles and open in succession. The type specimen in the 
Gray Herbarium is fragmentary. It was prepared from a 
plant cultivated in the Botanic Garden of Harvard Univer¬ 
sity and represents an early stage in the development of the 
inflorescence, only a single flower having opened when the 
specimen was made. The cluster of bracts subtending the 
pedicels is characteristic.
