New Species of South American Plants 145 



equal, hyalins, lanceolate, obtuse. Corolla 2 mm. long, cam- 

 panulate, lobed more than half-way, the lobes broadly ovate, 

 obtuse, the stamens exserted, the filaments long. Capsule 

 obovoid-oval, stipitate, compressed, setose, the margins acute, 

 the calyx-lobes persistent and somewhat enlarged, rigid and 

 acute. Seed oblong, compressed, tuberculate. 



"Erect or ascending, to 2 feet, the flowers white. Local in 

 open grasslands, 2,000 to 5,000 feet. Collected in Cuaco Mount- 

 ains, 4,500 feet, April 27." (Herbert H. Smith, Colombia, 

 No. 321.) 



Siphocampylus rectiflorus. 



Gray-tomentellate throughout, the calyx very slightly so. 

 Suffructicose, the branches ascending, slender, strongly ribbed 

 and sulcate, the internodes unequal, mostly 2 to 4 cm. long. 

 Petioles 8 to 12 mm. long, slender, the blades 4 to 6 cm. long, 

 I to 2 cm. broad, ovate with rounded base and gradually acumi- 

 nate acute summit, dentate with short triangular acute salient 

 teeth and shallow concave sinuses. Pedicels solitary in the 

 axils, half or more the length of the leaves, slender, spreading. 

 Calyx-tube turbinate, about half as long as the limb, the lobes 

 sub-equal, separate to the adherent portion, 10 to 13 mm. long, 

 regularly acuminate from the base to the acute summit, entire, 

 erect-spreading. Corolla lilac red, the tube 3.5 to 4 cm. long, 

 narrowly and regularly infundibular, the inner lip nearly 2 cm. 

 long, divided to the base into 2 linear obtuse lobes, the outer 

 slightly longer, divided two-thirds or more of the way into 3- 

 narrowly lanceolate sub-equal lobes. Two shorter anthers 

 strongly and densely penicillate at the summit and bearing 

 below this tuft, upon the back, a few coarse white bristles, the 

 two adjacent to them similarly and more strongly barbed below, 

 the. central one densely penicillate toward its summit. Style 

 at length well exserted and recurved, the stigma two-lipped, the 

 upper lip rounded, large, the lower small, lightly lobed. 



"Shrubby or suffrutescent and more or less diffuse, 3 feet." 

 Occasional in damp clearings and open places along streams at 

 about 4,500 feet. Collected at Las Nubes, December 5, (Her- 

 bert H. Smith, No. 1388). 



Siphocampylus declinatus. 



Younger portions of stems, petioles and veins of the lower 

 leaf-surfaces bearing scattered, very short white hairs, other- 

 wise glabrous. Branches erect, slender, strongly sulcate, the 

 internodes unequal, averaging about i cm. long. Petioles 5 

 to 10 mm. long. Blades 5 to 8 cm. long, i to 2 cm. wide, ovate 

 lanceolate with rounded base and long-acummate summit, 

 obsoletely coarse-serrate, thin, the principal veins strongly
