In the Bopi Kiver Valley, 3,000 feet, H. H. Rusby, August 

 11, 1921 {no. 591). The same collected by M. Bang, between 

 Tipuani and Guanai, December 1892 {no. 1665), and distributed 

 as "F. Radula Willd." 



Dr. Gleason, who kindly compared the specimen at Kew, 

 thinks it may be the same as Spruce's 2345, collected at San 

 Gabriel. 



Pourouma uvifera 



(Only fruiting specimens seen). Glabrous, except as to the 

 leaves and inflorescence, the branchlets short and very stout, 

 sharply annulate and heavily wrinkled in drying, the leaves be- 

 coming much larger than those here described. Petiole 2 dm. 

 long, terete, sharply several-sulcate. Leaves digitate, 9- to 11- 

 foliolate, the leaflets distinct or shortly confluent at the l)ase, 1 to 

 2 dm. long, 2.5 to 4 em. wide, oblanceolate, abruptly acuminate 

 and acute at the summit, obscurely sinuate at the margin, above 

 very shortly puberulent and slightly rough, and drying brown- 

 ish, beneath white and closel}" and softly tomentellate, the secon- 

 daries 20 to 25 on each side, slender, shortly decurrent at the 

 base, running straight to the margin at about 45 degrees, lightly 

 and sharply prominent on both sides, more so beneath, connected 

 by innumerable fine tertiaries. P'ruiting inflorescence only about 

 half as long as the petioles, the peduncles and branches stout, the 

 former slightly thickened upward and recurved, the young fruits 

 velutinous, very shortly and very stoutly pedicelled and slightly 

 umbilicate at the base, ovoid, tipped by a short and very broad 

 style and a broad depressed-capitate or discoid stigma. Mature 

 fruit glabrous, yellownsh-green, about 2 cm. long, sweet and muci- 

 laginous, the pulp clinging tightly to the seed. 



Rurrenabaque, 1,000 feet, FI. H. Rush}/, October 1921 {no. 

 1599). 



A large tree near the river, the edible fruit known as "Uva 

 del monte" (wild grape) and "Tanaribe." It is said that eat- 

 ing it to excess induces an obstinate and dangerous constipation.
