MEMOIRS OF THE KEW YORK BOTANICAL GARDEN 



On the shore of the Ibon River, 800 feet, M. Cardenas, Feb- 

 ruary, 1922 {no. 2085). "A small tree with red berries." Spe- 

 cies near P. nobilLs, but differs in the racemose inflorescence, the 

 far more numerous flowers on a flexuous raceme, and with prom- 

 inent elongate bracts. 



Phyllanthus biflorus 



Glabrous, the stems erect, very slender, 1 to 3 dm. high, sim- 

 ple or sparingly branched. Petioles very short, the blades 7 to 

 15 mm. long, 4 to 8 mm. wide, oval, nearly elliptic, some slightly 

 inaequilateral, thickish, entire, the venation slender and incon- 

 spicuous, the secondaries mostly 4 on each side. Flowers (al- 

 ways !) 2 in each axil, one staminate, the other pistillate, the 

 latter with a slightly shorter pedicel. 



Staminate flower : Pedicel short, recurved. Perigone 6- 

 parted, the segments subequal, nearly 2 mm. long, narrowly 

 oblong with rounded summit, white Avith broad green middle 

 band. Stamens 6, about half as long as the perigone, connate 

 for about half their length. 



Pistillate flower: Perigone-segments little more than half 

 the size of those of the staminate flower, and relatively broader. 

 Ovary subglobose, the styles connate at the base, bifid, recurved. 

 Capsule 1.5 mm. long and broad, green, shining. Seeds light- 

 brown. 



Along the Bopi Eiver, 3,000 feet, H. H. Rushy, September 12, 

 1921 {no. 662, type). Also near Eurrenabaque, 1,000 feet, M. 

 Cardenas, December 1, 1921 {no. 1746; this form about 3 dm. 

 high). 



Phyllanthus ichthyomethius 



Subglabrous, the stems roughly nodose from the fallen 

 branchlets, flexuous, densely branched, the branches slender, 

 more or less angled or sulcate, densely leafy. Petioles 1 or 2 

 nun. long, very slender, minutely puberulent. Blade 1 to 3 cm. 

 long, 5 to 15 mm. wide, ovate, often slightly inequilateral, mth 

 blunt base and mostly obtuse summit, entire, thin, bright-green, 

 the venation sparse and very slender. Fascicles many-flowered, 

 the filiform pedicels sometimes more than 1 cm. long. Only stam- 

 inate flowers found, the perigone 6-parted nearly to the base, 

 the segments nearly 2 mm. long, oblong, the outer three some- 

 what broader than the inner. Stamens 6, not quite half the
