flowers. Calyx campanulate, 1.5 cm. long, divided nearly to 

 the base, the lobes broadly ovate, acuminate. Corolla scarlet, 

 densely strigose, 1.5 cm. long, 6 mm. broad, infundibular, 

 straight, not gibbous, slightly ventricose, the mouth slightly 

 contracted, sub-equal, the lobes ovate, acute, about 3 mm. long. 

 Disk on one side, thin, about 2 mm. long, 3-toothed. Stamens 

 about as long as the corolla, but the filaments strongly curved 

 and the anthers included, the filaments all connate at the base 

 on one side, and adherent to the base of the corolla, one pair 

 of anthers coherent. Ovary pilose, ovoid, 3 mm. long, the 

 style 12 mm. long, the stigma lightly 2-lobed. 



Miguel Bang, Bolivia, No. 853, distributed as " C. adscen- 

 dens." 



Colutnnea grandifolia. 



Upper leaf-surfaces rather sparsely, the remainder densely 

 long-strigose. Leaves sessile, 2 to 3 dm. long, 6 to 8 cm. broad, 

 oblanceolate, with slightly inequilateral basal portion and 

 abruptly short-pointed acute summit, the margin minutely and 

 sparsely denticulate and ciliate; thin, above deep-green, be- 

 neath gray-tomentose, the venation obscure. Bracts longer 

 than the calyx, ovate, attenuate, sparsely pinnatifid with fili- 

 form lobes. Calyx 1.5 cm. long, i cm. broad, campanulate, 

 parted nearly to the base, the lobes sub-equal, lanceolate, long 

 attenuate, pinnatifid with long, filiform, hirsute lobes, green- 

 nerved on the back. Corolla nearly 3 cm. long, 6 or 7 mm. 

 wide, cylindrical, straight, contracted and slightly gibbous 

 at the base, slightly ventricose, slightly contracted toward the 

 summit, the mouth sub-equal. Disk half the length of the 

 stoutly conical pilose ovary, 2-lobed, the lobes short, with 

 rounded summit. Bases of filaments dilated, connate, adher- 

 ent to the base of the corolla, the anthers coherent. Style 

 very slender. 



"A shrub a meter high, at San Carlos, Mapiri, Bolivia, 700 

 meters altitude, August 3, 1907." (Otto Buchtien, No. 1972.) 



Buchtien's 2245, from near Cochabamba, 750 M. alt., Jan- 

 uary, 1909, is probably the same, but corollas are not present. 



Colutnnea (Systelostoma) latifolia. 



Stems and lower leaf-surfaces pubescent, the upper leaf- 

 surfaces densely strigose. Petioles 1.5 to 2.5 cm. long, broad, 

 channelled above, lightly carinate beneath. Blades 7 to 12 cm. 

 long, 4 to 8 cm. broad, ovate with obliquely rounded base and 

 abruptly very short-pointed acute summit, obsoletely sinuate- 

 dentate, very thin, deep-green above, but somewhat grayish from 

 the indumentum, deep-purple underneath, the venation broad, 

 impressed above, prominent beneath, the secondaries about
