122 New Species of South American Plants 



Miguel Bang, Bolivia (No. 2535). 



Distributed as "A bracteata (Cham.) DC." and very 

 near that species. 



Adenocalymna symmetrica. 



Glabrous, with the possible exception of the inflorescence, 

 which is not present in the specimen. Branchlets slender, sul- 

 cate, multi-foveolate at the base of the nodes, bearing two 

 approximate pairs of leaves near the summit, the lower pair 

 much smaller, and having one of the lateral leaflets of each leaf 

 converted into a short, slender tendril, the petioles 1.5 or 3 cm. 

 long, terete, foveolate at the summit, the lateral petiolules 4 to 

 9 mm., the terminal 5 to 25 mm. long. Leaflets 7 to 12 cm. 

 long, 2 to 5 cm. broad, lanceolate, acute, thickish, the lateral 

 smaller than the terminal in the lower pair, larger in the upper 

 and with oblique subcordate base, that of the terminal equal 

 and slightly cordate. All the venation prominent on both sur- 

 faces, 5 to 7 small nerves radiating from the summit of the 

 petiolule, the remaining secondaries about 10 on each side, very 

 slender, little curved but crooked, bifurcating and connecting 

 at some distance from the margin, the venation finely and 

 strongly reticulate. Calyx not seen. Single corolla present 

 minutely puberulent, the tube proper 2 cm. long, slightly con- 

 tracted above, the throat 2.5 cm. long, infundibular, the two 

 upper lobes 2 cm. long, the lower three shorter and relatively 

 broader. Stamens included, not seen. 



Rusby and Squires, lower Orinoco, Venezuela, 1896; with- 

 out number or locality, and not duplicated. 



Besleria debilis. 



Younger portions, inflorescence and lower leaf-surfaces pyb- 

 erulent. Stems slender, ascending, weak, sulcate. Petioles to 

 3 cm. or more long, slender. Blades 8 to 15 cm. long, 3 to 6 

 cm. wide, inequilaterally ovate, acuminate and acute at both 

 ends, obsoletely serrate, very thin, the slender venation slightly 

 prominent beneath, the secondaries about 7 on each side, 

 strongly falcate-ascending and faintly connecting to form the 

 margin of the leaf. Peduncles axillary, shorter than the petioles, 

 filiform, the pedicels similar and about equal, 2 to 5 in number, 

 arising together from the summit of the peduncle. Calyx 

 parted almost to the base, the lobes ovate, abruptly contracted 

 into narrow green appendages, thin, colored, the longest 7 mm., 

 the shortest nearly as long, loosely enveloping the base of the 

 corolla, which is nearly 2 cm. long, narrowly campanulate, 

 gibbous at the base and ventricose near the mouth, which is 

 shortly 5-toothed, the teeth ovate, acute. Filaments attached 

 5 mm. above the base of the corolla, the bases dilated and coher-
