A tree 20 30 feet high. Branches slightly winged, purplish brown. 

 Leaves alternate, obovate or oblong, obtuse, obscurely emarginated, 

 narrowing into a very short petiole. Cymes axillary, on long stalks 

 little shorter than the leaves. Flowers small. Calyx with rounded 

 lobes. Petals white, erert, lanceolate, obtuse. Anthers fringed, with 

 a tongue-shaped appendage much longer than the lobes. Hypogynous 

 scales bifid, adhering into a toothed cup. Drupe 4-5 lines long, 

 purple, with a soft sweet eatable flesh. This plant, the Umm of the 

 people of Para, yields from its trunk when wounded a valuable, fragrant, 

 limpid, pale yellow balsam called Balsam of Umiri, possessing the same 

 medicinal qualities as Balsam of Copaiva, "immo nobiliorem et balsamo 

 peruviano cemulum." Martitis.

 plexicaule Schreb. gen. No. 901. A Guiana plant, with ovate 

 or ovate-oblong acute sessile half-amplexicaul leaves, yields a 

 similar balsam, which Aublet compares to that of Peru ; it is the 

 Houmiri or Touri of the Caribs.
