the latter deep-l)roAX n, enclosing and longer than the pedicels. 

 Fruiting calyx 3 or 4 cm. long, the tube nearly a third of the 

 length and about as broad as long, the limb narrowly oblanceo- 

 late with rounded summit, the nai-rowly linear, acuminate petals 

 reaching tlie base of the limb and exceeding the short, slender, 

 distinct styles. Nut nearly as broad as long, strongly and 

 sharply winged. 



Meguilla, 3,000 feet, H. H. Rushij, July, 1921 {no. 2175). 

 Species totally unlike any other in its leaf-form and indu- 

 mentinn. 



Triplaris setosa 



Profusely setose-hairy, the hairs ferruginous, divergent or 

 even slightly retrorse. Branches slender, terete, densely leafy. 

 Ochreae not seen. Petioles very short and stout. Blades 2 to 3 

 dm. long, 6 to 10 cm. wide, lanceolate, with cordate subclasping 

 base and acuminate and acute summit, entire, ciliate, thickish, 

 the venation slender, sharply prominent on both sides, the sec- 

 ondaries 30 or more on each side, falcate, ascending, and very 

 lightly connecting near the margin, connected by numerous slen- 

 der crooked tertiaries. Panicle (but one seen) terminal, small, 

 densely fruited. Fruiting calyx-tube 1.5 cm. long and 1 cm. 

 broad, the entire calyx 5 cm. long, 7 mm. wide, somewhat un- 

 equal, narrowly oblanceolate, the basal portion a half broader 

 than the limb. Petals little exceeding the basal portion of the 

 sepals, but exceeding the styles, which are a third as long as the 

 nut and coherent for nearly half their length. 



Near Covendo, 2,000 feet, 0. E. White, August 20, 1921 (no. 

 910). 



This species is closely related to T. liispida Britton, which 

 has appressed bristles on the midrib and is of very different leaf- 

 form and habit. 



Ruprechtia scandens 



Stems woody, thick, twining high and \\'idely, fistulous, the 

 branchlets terete, striate, puberulent. Ochreae 3 or 4 mm. long, 

 with oblique truncate summit, appressed-pilose. Petioles about 

 8 mm. long, stout, mostly twisted, the margins involute. Blades 

 1 to 2 dm. long, 3 to 5 cm. broad, oblong, with obtuse base and 

 abruptl}^ very short-pointed obtusish smiimit, rigid, entire, pu- 

 berulent above, becoming glabrous, with the midrib and 12 to 15 

 pairs of secondaries impressed, somewhat harsh beneath, the
