72 New Species of South American Plants 



Maieta robusta. 



Sparsely coarse-pilose, the leaves strongly ciliate. Branch- 

 lets stout, rough with the broad shallow leaf-scars. Naked 

 portion of petiole 5 to 8 mm. long, stout, strongly channelled 

 and strongly ciliate, the bladder-bearing portion about 2 cm. 

 long, the inner margin of the bladder slightly exceeding it. 

 Bladder narrowly turbinate, nearly i cm. broad at the summit, 

 very finely many-nerved, the nerves ascending from the adnate 

 petiole. Blades 12 to 20 cm. long, 6 to 10 cm. broad, oval or 

 ovate, the base slightly produced into the petiole, the summit 

 abruptly pointed, the point short, narrow and acute; flabellately 

 5-ribbed, the lateral ribs close to the margin, all prominent 

 underneath and connected by straight nearly divaricate slen- 

 der secondaries. Axillary panicles sessile or short-peduncled, 

 small and few-flowered, little exceeding the bladders, their 

 branches linear-subulate bracted, as is the base of the calyx. 

 Pedicels slender, thickened upward. Calyx- tube 6 mm. long, 

 turbinate, the strongly ciliate, subulate, attenuate teeth nearly 

 as long, spreading or erect. Perfect petals not seen. Fila- 

 ments stout, about as long as the anthers. Capsule urceolate, 

 about 5 mm. long. 



Collected on the upper Rio Negro, near the Colombian 

 border, by Weiss and Schmidt in 1908. 



Harttnannia Boliviana. 



Sparsely puberulent. Stems to 2 dm. long, slender, weak, 

 crooked, prostrate or ascending, terete, purplish. Radical 

 leaves to 3 cm. long, and 8 mm. wide, oblanceolate with long 

 tapering petiole-like base and obtuse summit, entire, thick, 

 deep-green, obscurely 3-nerved, the venation obscure, the cau- 

 line similar, but half as long or less, ovate or oval, with short 

 base and acute summit. Only one imperfect flower present in 

 my specimen, the corolla deep-red. Fruit purple, sessile, nearly 

 1.5 cm. long, 4.5 mm. wide at the summit, club-shaped, curved 

 to a third of a circle, bearing four narrow wings which broaden 

 upward and are mostly greenish, and between them very strong 

 purple ribs. Beak very short and broad, shortly 4-toothed. 



On Titicaca Island in Titicaca Lake, Bolivia, March, 1910, 

 (Otto Buchtien, No. 2922.) 



Pentapanax granatensis. 



Glabrous. "Leaves thrice pinnate, some of the ultimate 

 segments pinnate" (Smith). Only one primary segment of 

 leaf seen, namely that next to the basal segment. This is 

 about 3 dm. long and broad, its petiole 7 cm. long, bearing 4 

 opposite pairs of long and slenderly petioled divisions, and 

 several single leaflets, these branches bearing from i to 4 pairs
