New Species of South American Plants 103 



underneath finely puberulent, or at length becoming nearly 

 glabrous. Flowers in a small terminal panicle and in the upper 

 axils, the latter in threes on a peduncle shoiter than its petiole. 

 Pedicels mostly longer than the calyx, subulate-bracted at the 

 base, the bracts attenuate. Calyx about 5 mm. long and broad, 

 cupulate, the sepals broadly elliptical, the outer densely ferru- 

 ginous, the inner slightly so and purple. Tube of corolla about 

 as long as the calyx, the campanulate limb a little more than 

 twice as long, coarsely pilose externally. Stamens included. 

 Style persistent, filiform, a little shorter than the corolla, its 

 branches about a third of the total length, the purple stigmas 

 capitate, large. 



"A twiner, to 20 feet. Rare in borders of forest below 

 1000 feet. Specimen collected 5 miles south of Mamatoca, at 

 about 800 feet, November 21." (Herbert H. Smith, Colombia, 

 No. 877.)" 



Maripa repens. 



Lower leaf-surfaces very minutely and sparsely puberulent. 

 Stems elongated, terete, creeping in mud which is at times 

 inundated, the few ascending branches sparsely leafy. Petiole 



2 cm. long, weak, narrowly margined, the blades i to r.5 dm. 

 long, 4 to 6 cm. broad, thin, oval, with cuneate base, the summit 

 not seen, entire, the midrib very slenderly sulcate above, sharply 

 prominent beneath, the principal secondaries about 8 on a side, 

 falcately ascending and disappearing in the margin, the remain- 

 ing venation inconspicuous. Peduncle lateral, short and stout, 

 the panicle short, broad, loosely flowered, the bracts very small, 

 broadly ovate, acute, thick and, rigid. Pedicels a little longer 

 than the calyx, stout, striate. Flower 2.5 cm. long, the calyx 

 a fourth of its length, the sepals equal, rounded at the ciliate 

 summit, thick and rigid, minutely muricate, the corolla narrowly 

 campanulate, lobed more than a third of the way,- the lobes 

 sericeous, ovate, obtuse. Stamens equal, i cm. long, the fila- 

 ment filiform, a little longer than the anther, which is short- 

 auriculate at the base. Style about equaling the stamens, 

 entire, the stigma large, broader than long, its base cordate. 



Collected by Rusby and Squires at Sacupana, lower Orinoco, 

 Venezuela, without number. Plant creeping in clay soil, 

 along a river-bank. 



Ipomoea hilarifolia. 



Glabrous. Branches striate and lightly sulcate. Petioles 



3 to 5 cm. long, slender, the blades 2.5 to 4 cm. long from the 

 petiole to summit, 2 to 5 cm. broad, exclusive of the basal lobes, 

 ovate with abruptly short-acuminate summit and cordate base, 

 the basal lobes more than half the length of the body, broadly
