  • Discussion

    Distribution and ecology - Rurrenabaque, 1,000 feet, M. Cardenas, October 12, 1921 (no. 1256). "Fruit edible, and known locally as 'Achachairu.' A shrub or small tree of the forest, with yellow fruit." A specimen, collected by Dr. White (no. 1476) appears to me to be the same, although he says that the fruit has a waxy bloom, and is bluish, possibly because immature.
