ascending, the venation finely reticulate, impressed above, 

 prominent underneath. Pedicels in the upper axils, 4 to 8 cm. 

 long, bearing two lance-linear bracts at about the middle. 

 Calyx divided almost to the base, the lobes about 2 cm. long, 

 erect, slightly unequal, lanceolate, acuminate, coarsely serrate, 

 reticulate veined. Corolla dull-red, whitish within, somewhat 

 declined, the tube nearly 4 cm. long, infundibular, slightly 

 inequilateral, the lower lobes a little more than i cm. long, 

 lanceolate, acute, nearly equal, spreading or recurved, the upper 

 lip shortly 2-lobed, the lobes narrowly lanceolate. Anthers 

 about 8 mm. long, curved, the upper naked, the stigmas lightly 

 exserted. 



"Somewhat diffuse, the branches erect to 4 or 5 feet. Com- 

 mon on open lands of Sierra del Libano and San Lorenzo Ridge, 

 6,000 to 7,500 feet. Collected January 25 at about 6,500 feet." 

 (Herbert H. Smith, Colombia, No. 1384.) 



Centropogon foliosum. 



All young portions and both leaf-surfaces densely yellow- 

 ish-tomentose, the older portions more sparsely so. Stems 

 erect, stout, flexuous, coarsely sulcate, densely leafy above. 

 Petioles 3 to 5 cm. long, stout, ascending, the blades 10 to 15 

 cm. long, 4 to 6 cm. broad, ovate, abruptly contracted into 

 the petiole, rather abruptly acuminate at the acute summit, 

 obscurely serrate-dentate, the teeth minute; thin, yellowish- 

 ■ green, the principal secondaries about 15 on each side, strongly 

 falcate, broad and flat, densely tomentellate, the upper surface 

 less so. Pedicels solitary in the upper axils, 4 to 6 cm. long, 

 stout. Calyx deltoid, the tube 4 to 5 mm. long and 10 or 12 

 mm. broad, with truncate and umbilicate base and contracted 

 summit, the triangular acute lobes a little longer, appressed 

 about the base of the corolla. Tube of the corolla about. 3.5 

 cm. long, 12 mm. wide as pressed, the back fissured half-way, 

 mfundibular, straight and equable, or nearly so. Mouth only 

 slightly open, both lips strongly curved, the upper nearly a half 

 longer, its two lobes lance-ovate, acuminate and acute, the 

 lower less deeply three-lobed, the lobes sub-equal, and of similar 

 form to the upper. Stamen-column pilose, its exserted portion 

 about 10 mm. long, the anthers nearly i cm. long, the lower 

 strongly white-penicillate. Stigma large, pilose, sub-equally 

 2-lipped. 



" Erect, 4 to 5 feet, the corolla orange-red. In damp clear- 

 ings, Sierra del Libano, 6,000 feet, January 22" (Herbert H. 

 Smith, Colombia, No. 1385).
