90 New Species of South American Plants 



disk, which is longer than the ovaries and is shallowly lobed, 

 the lobes with broad rounded summits. Corolla-tube proper 

 twice the length of the calyx, cylindrical, about 3 mm. thick, 

 the throat broadly campanulate, about 2 cm. long and equally 

 wide at the summit, the limb broadly campanulate, about 5 

 cm. broad. Stamens inserted at the pilose summit of the tube, 

 the filaments very short, the anthers short, ovoid, acute. Young 

 follicle 25 cm. long, very slender, torulose. 



"A twining vine, to 6 or 8 feet. Corolla bright-yellow. 

 Occasional in clearings and edges of forests near Las Paitidas 

 and Valparaiso, 3000 to 4500 feet. Flowers March to July. 

 Collected at Las Partidas, 3500 feet, June 2." 



(Herbert H. Smith, Colombia, No. 1663.) 



Forsteronia foliosa. 



Inflorescence tomentellate. Branchlets slender, elongated, 

 irregularly angled, the internodes 5 or 6 cm. long. Petioles 

 about I cm. long, stout, deeply channeled on the thin margins, 

 involute. Blades 7 to 12 cm. long, 3 to 7 cm. broad, ovate 

 with rounded base and very shortly and acutely pointed, deep- 

 gr^en above, drying brownish beneath, feeling downy to the 

 touch, but the indumentum imperceptible. Secondaries 8 to 

 10 on each side, lightly curved and obscurely connecting at 

 some distance from the margin, connected by the tertiaries and 

 by a very fins reticulum that is impressed on both surfaces. 

 Panicle terminal (but one seen), 10 cm. long, including the 

 peduncle, which is 3 cm. long, the width of the dense panicle 

 3.5 cm., the flowers not yet expanded, sessile. Calyx two- 

 fifths the length of the bud, lobed nearly half way, the lobes 

 broad with rounded summit. 



Species very near to F. mollis Rusby, but undoubtedly 

 distinct. 



"Polo-Polo, near Corioco, Bolivia, iioo M. altitude, Nov- 

 ember II, 1912." (Otto Buchtien, No. 3876.) 

 Prestonia tnucronata. 



Ferruginous-pubescent throughout, the branches elongated 

 and slender, terete, the internodes mostly shorter than the 

 leaves. Petioles 12 to 15 mm. long, suberect, the blades spread- 

 ing, 6 to 8 cm. long, 3.5 to 4.5 cm. broad, oval with rounded base 

 and rounded mucronate summit, thickish, the venation slender, 

 lightly prominent on both sides, more so beneath, the second- 

 aries about 5 on each side, nearly straight, ascending. Flower- 

 ing peduncle 6 or 7 cm. long, slender, the cyme about 6 cm. 

 broad, rather densely flowered, the bracts small, subulate, the 

 pedicels rather stout, shorter than the flowers. Calyx about 

 I cm. long, equalling the corolla-tube, the lobes ovate, acumi-
