New Species of South American Plants 125 



leaves extremely unequal. Petioles 2 to 10 mm. long, purple^ 

 pilose, the blades 2 to 10 cm. long, i to 3 cm. broad, lance-ovate 

 and more or less inequilateral, with obliquely rounded base and 

 obtuse summit, coarsely dentate-serrate with obtusish teeth 

 and sinuses, very thin, bright-green above, purplish beneath , 

 especially the coarse veins, the secondaries about 8 on each 

 side, strongly ascending or sub-erect on the narrow side, little 

 curved, connected by few tertiaries. Pedicels axillary, solitary, 

 very slender, more than half as long as their leaves, purple, 

 pilose. Calyx i cm. broad, the tube short, crateriform, the 

 lobes ovate-acuminate but obtusish, the midrib and a pair of 

 faint nerves purple. Corolla rotate, nearly 2 cm. broad, the 

 lobes oval, nearly elliptical, the margins incurved so as to make 

 the lobe concave. Stamens shorter than the corolla-lobes, the 

 filaments slender, the anthers at first coherent, later apparently 

 separating. Style a little longer than the stamens, purple, 

 the stigma small, concave. 



"Petals white. Rare on damp rocks, in glens and on ridges 

 on the Sierra Onaca, 4,000 to 5,000 feet; August 22." (Her- 

 bert H. Smith, No. 2506.) 



Columnea stricta. 



Upper leaf-surface sparsely short-strigose, otherwise densely 

 strigose-tomentose. Stems stout, strict, terete. Leaves sessile, 

 10 to 20 cm. long, 3 to 4.5 cm. broad, oblanceolate, nearly equi- 

 lateral, abruptly short-pointed and acute, minutely denticu- 

 late, thin, deep green above, gray-tomentose beneath. Bracts 

 2 cm. long, inequilaterally lanceolate, long-acuminate. Flowers 

 short-pedicelled. Calyx 1.5 cm. long, 6 mm. broad, infundi- 

 bular, lobed nearly to the base, the lobes slightly unequal, 

 lanceolate, attenuate, sharply serrate. Corolla 3 cm. long, 7 

 mm. wide, infundibular, straight, slightly gibbous at the base, 

 not or slightly ventricose, the mouth equal. Disk small, 2- 

 lobed. Ovary long, tufted at the summit. Anthers and stigma 

 slightly exserted, the anthers very slightly or not at all coherent, 

 small. 



"Espirito Santa, near Cochabamba, Bolivia, 750 meters 

 altitude, June 1909." (Otto Buchtien, No. 2209.) 



Columnea pallida. 



Densely long-strigose throughout, the stems stout, densely 

 flowered and leafy toward the summit. Leaves sessile, 15 to 20 

 cm. long, 4 to 6 cm. broad, lanceolate or oblanceolate, somewhat 

 inequilaterally acuminate at the base, short-acummate and 

 acute at the summit, denticulate with salient teeth, thm, yellow- 

 ish-gray green, the venation inconspicuous. Bracts lance- 

 ovate with attenuate summits, mostly about as long as the
