74 New Species of South American Plants 



or slightly reflexed. Petioles very short and broad, the blades 

 8 to 12 mm. long, 4 to 6 mm. broad, ovate, with rounded base 

 and acute summit, thick, very smooth, serrate with thick teeth, 

 the venation prominent on both sides, very strongly so beneath, 

 the secondaries about 3 on each side, strongly ascending, slightly 

 curved, thick. Flowers sub-solitary in the upper axils, the 

 peduncles half as long as the leaves, angled, bracted upon the 

 base, the bracts subulate. Calj^ 5 or 6 mm. broad, lobed 

 about half-way, the lobes ovate, thick, mucronulate. Corolla 

 6 mm. long, the mouth somewhat contracted, the teeth short, 

 recurved, acute. Stamens half the length of the corolla, the 

 filament about as long as the anther, very slender, the anther 

 ovoid, the awns exceeding it and extremely slender. Ovary 

 depressed-globose, the style stout, about as long as the ovary. 

 Berry slightly 5-lobed, 6 mm. broad. 



"A shrub to i foot high, on top of San Lorenzo Ridge, 6,500 

 to 7,500 feet, February 7." (Herbert H. Smith, No. 1721.) 

 Apparently the same as Helton's No. 626. 



Gaultheria tetriches. 



Lower leaf-surfaces shortly and sparsely rough-hairy, the 

 branchlets, inflorescence, etc., glandular-hairy. Branchlets 

 stout, widely spreading, flexuous, terete, deep purple-brown. 

 Petioles 3 to 5 mm. long, strongly channelled above, the blades 

 5 to 7 cm. long, 2 to 4 cm. broad, ovate with lightly cordate 

 base, and cuspidate summit, entire, thick, pale-green, drying 

 yellowish, the principal venation strongly impressed above, 

 all very prominent and strongly and finely reticulate beneath, 

 the secondaries 5 on each side, strongly ascending, more or less 

 falcate, irregularly connected by the tertiaries. Racemes 

 terminal, simple or branched at the base, shortly peduncled, 5 

 to 10 cm. long, loosely flowered, the bracts 10 to 12 mm. long, 

 obovate with narrowed base and mucronate summit, purple, 

 thick, finely and strongly many -nerved. Pedicel and flower 

 each 6 mm. long, the calyx 6 mm. broad, lobed about half way, 

 densely hairy, like the corolla, slightly umbilicate at the base. 

 Corolla broadly ovoid, contracted to the mouth, the lobes very 

 small, lanceolate, strongly recurved. Stamens 10, somewhat 

 unequal, the filaments a half longer than the anther, flattened, 

 dilated downward, broad, pilose on the back, the hairs deflexed, 

 the anther oval, obtuse, 4-setose near the summit, the setae 

 nearly half the length of the thecae, straight, erect. 



"Unduavi, Bolivia, 3,300 m. altitude, November 1910. A 

 shrub to 2 meters." (Otto Buchtien, No. 2930.) 



Gaultheria fendleri. 



Veins of the lower leaf-surfaces pilose with coarse deciduous 

 hairs, the rachis and pedicels ferruginous with divaricate hairs.
