New Species of South American Plants 75 



Branchlets numerous, short, stout, terete, puberulent, erect- 

 spreading, leafy to the base of the inflorescence. Petioles 5 or 

 6 mm. long, channelled above, the blades 4 to 6 cm. long, 2 to 

 2.5 cm. wide, with rounded or truncate base, very slightly 

 produced into the petiole, the summit short-cuspidate, the 

 revolute margin obscurely denticulate; very thick, drying 

 brownish, the midrib impressed above, the principal secondaries 

 4 or 5 on each side, with intermediate ones sometimes equally 

 strong, strongly falcate-ascending, crooked and connected by a 

 crooked network of tertiaries. Racemes in the upper axils and 

 terminal, rather densely flowered, sub-sessile with a number of 

 closely imbricated basal bracts, about 2 mm. long and 4 mm. 

 broad, the lower successively smaller, finely many-nerved, the 

 summit rounded. Bracts of the raceme somewhat similar, 

 larger, concave, at length reflexed. Pedicels 4 to 6 mm. long, 

 pubescent with short, white, divaricate hairs. Flowering calyx 

 4 or 5 mm. broad, divided about half way, the lobes ovate, 

 obtusish or acute. Corolla 5 mm. long, mostly loosely enclosed 

 by the calyx or the latter at length spreading widely; slightly 

 contracted upward, lobed nearly half way, the lobes broadly 

 ovate, acute. Stamens slightly unequal, the longer more than 

 half the length of the corolla, the filament more than twice the 

 length of the anther, slender, the very slender awn of the anther 

 nearly terminal, less than half as long as the anther, the cells 

 minutely mucronulate. Ovary depressed-globose, shorter than 

 the calyx, the style stout, about as long as the ovary. "A 

 shrub 2 to 3 feet high, in open ground, top of San Lorenzo 

 Ridge, 6,500 to 7,500 feet, February 27. Flowers white. (Her- 

 bert H. Smith, Colombia, No. 17 19.) The same as Fendler's 

 741, and also collected by Burchell. 



Macleania robusta. 



Glabrous. Branchlets erect, stout, terete, leafy to the sum- 

 mit. Petioles 5 to 7 mm. long, very stout, fleshy, rugose in 

 drying, the blades 4 to 7 cm. long, 2 to 3.5 cm. broad, oval with 

 rounded base and blunt or sub-rotund summit, entire, thick, 

 drying brownish, the principal veins slenderly impressed above, 

 prominent beneath, 3 or 4 pairs of secondaries originating below 

 the middle and strongly decurrent on the midrib, the upper 

 ones faint and loosely anastomosing. Racemes in the upper 

 axils and crowded at the summit, few-flowered, bracted at the 

 base, the bracts imbricated, small, broadly ovate, obtuse or 

 acute. Peduncles very short, the pedicels at length 2 cm. long, 

 thickened upward, 2-bracteolate below the middle, the bracts 

 very small, ovate, acute. Calyx articulated to the pedicel, 

 the tube 2 mm. long, 3.5 mm. broad, the limb 6 or 8 mm. broad, 

 about as long as the tube, shortly and very broadly 5-toothed, 

 the teeth acute. Corolla 13 mm. long, slightly ventricose
