New Species of South American Plants 133 



cm. broad, lance-oblong, acuminate and acute at both ends, 

 entire, thin, deep-green, the venation impressed on the upper 

 shining surface, strongly prominent beneath, the slender second- 

 aries about 8 on a side, falcate-ascending, connecting at some 

 distance from the margin, the remaining venation very loosely 

 reticulate. Fruit sessile at the base of a terminal leaf, mostly 

 recurved, 5 cm. long, broadly oval, finely many-nerved, brown, 

 smooth, the base rounded, the summit tipped by the calyx- 

 tube, about 4 mm. long, with short teeth. Seeds compressed, 

 irregularly triangular with obtuse angles, 7 to 9 mm. long and 

 nearly as broad, light-brown, the surface granular-roughened. 

 "Catalina, lower Orinoco, Venezuela, May 1896." (Rusby 

 and Squires, No. 222.) No. 173 is the same, without flowers 

 or fruit. 



Duroia sprucei. 



(Fruiting specimen) 



Glabrous, the branchlets stout, blackish, the concave leaf- 

 scars crowded, 4 mm. wide, lightly obcordate, connected by 

 narrow stipule-bases. Interpetiolar stipules imperfect in my 

 specimen, apparently retuse at the summit, finely ciliate. 

 Petioles 12 to 15 mm. long, stout, channeled above and keeled 

 beneath, the blades 10 to 13 cm. long, 4 to 5 cm. broad, oblance- 

 olate with acuminate base gradually contracted into the petiole, 

 and rounded or blunt summit, entire, thick and coriaceous, 

 drying brown, somewhat shining above, the slender venation 

 sharply prominent beneath, the secondaries about 10 on each 

 side, strongly ascending and little falcate, connecting at or very 

 close to the margin, the venation very finely and strongly reti- 

 culate. Fruit sessile, 5 cm. long, 3 cm. broad, produced at the 

 base into a very short stout stipe, and tipped with a calyx-tube 

 4 mm. long and 6 mm. broad, glabrous and somewhat shining, 

 wrinkled . 



Sacupana, lower Orinoco, Venezuela, April, 1896 (Rusby 

 and Squires, No's. 171 and 172.) The same as Spruce's 3624. 



Alibertia granulosa. 



Glabrous. Branchlets short, widely spreading, tarete, 

 wrinkled, purplish. Stipules connate, about 6 mm. long, ovate, 

 acute, membranaceous. Petioles i to 1.5 cm long, broad, the 

 blades 8 to 16 cm. long, 3 to 6 cm. broad, oblong with obtuse 

 base and abruptly acuminate and obtuse summit, thickish, the 

 venation slender, conspicuous on the lower surface, the second- 

 aries about 8 on a side, moderately ascendmg, and lightly 

 curved, not connecting, the remaining venation obscure, i^ruit 

 sessile, globose, about 2 cm. broad, brown granula-roughish 

 (becoming smooth ?), the calyx-tube 4 mm. long, 3 mm. broad.
