 Blades to 1 dm. long and half as broad, nearly elliptic, both base 

 and summit very lightly produced, obtuse, entire, thick, yellow- 

 green and strongly shining, the midrib very strong beneath, 

 much wrinkled, mostly thinly channeled above; pectinately 

 veined, the secondaries extremely numerous, nearly at right 

 angles with the midrib. Cymes few-fruited, short-peduncled, 

 the peduncles and short pedicels slender, erect, spreading. 

 Fruits in the dried state globose, 2 to 2.5 cm. broad, bearing

Rurrenabaque, 1,000 feet, M. Cardenas, October 12, 1921 {no. 

 1256). "Fruit edible, and known locally as 'Achachairu.' A
