oval, with obtuse or aciitish base and acute suiiiinit, relatively

 ondaries, about 10 on each side, widely spreading-, then strongly 

 ascending- and conned ini;- at some {iistance from the maroin, 

 connected with one anotlier and with the midrib by mimerous 

 straightish and very slender tertiaries. Fruits borne on nodules 

 of the leafy branchlets. Pedicels slender, regularly thickened 

 upward, 1 to 2 em. long. Calyx 2 to 2.5 cm. broad, strongly 

 veined, the margin obscurely sinuate. Drupe 1 cul long, 7 muL 

 broad, oval and near'ly elliptic. 



Ixiamas, 1,500 feet, Martin Cardenas, December 13, 1921 (wo.

Species near H. cauliflora Smith, but well distinguished by 

 its pedicellate fruits. 



POLYGONACEAE 



Coccolobis padifolia 



Glabrous. Branchlets numerous, short and stout, very flexu- 

 ous, coarsely angled. Sheaths short and broad. Bracts coria- 

 ceous, triangular-ovate, broader than long, short-acuminate and 

 acute, erect. Petioles to 1 cm. long, stout, sulcate. Blades to 12 

 by 4 cm., regularly lanceolate with rounded base and obtuse or 

 acutish summit, entire, thick and coriaceous, the slender vena- 

 tion prominent on both sides, finely and very strongly anasto- 

 mosing, the secondaries about 8 or 10 on each side, ascending at 

 a little more than 45 degrees, strongly falcate. Racemes ter- 

 minating short branchlets, the base sheathed with imbricate 

 scales, shortly peduncled and mostly subtended by a miniature 

 leaf; mostly 2 to 3 cm. long, slender, loosely flowered. Pedicels 

 filiform, about 3 mm. long. Sepals 5, imbricate, petaloid, 2 mm. 

 long. Corolla wanting. Stamens equal, the filaments dilated 

 tow^ard the base and slightly connate, the anthers rounded. 

 Styles 3, the stigmas flattened, their margins crenate-lobed. 

 Ovary ovoid, short, the base enclosed in the short stamen-tube. 



Rurrenabaque, 1,000 feet, H. H. Rushy, October 7, 1921 {no. 

 848). 



Triplaris Williamsii 



Branchlets stout, flexuous, dark-brown. Ochreae caducous, 

 not seen. Petioles 2 to 2.5 cm. long, very stout, strongly grooved 

 by the very acute, rigid, involute margins. Blades 2 to 5 dm.
