to narrowly subulate. Tendrils elongate, slender, mostly flat- 

 tened, at least toward the base. Petioles about 1 cm. long, slen- 

 der, brown, apparently glandless. Blades about 6 mm. long and 

 12 cm. wide, the base slightly cordate, the summit slenderly aris- 

 tate, the two lobes almost directly divaricate, scarcely 1 cm. 

 wide, lanceolate with slightly narrowed base and mostly obtuse 

 summit, entire, a small circular whitish gland at the junction of 

 the central and lateral ribs. Leaf thin, the venation prominent 

 on the lower surface, the secondaries of each lobe numerous, 

 connecting with one another in a sinuous line near the lower 

 margin, and, near the upper margin, with a secondary from the 

 midrib. Peduncle 5 cm., or more long, 1-flowered, very slender. 

 Bracts 1.5 cm. long, 3 or 4 mm. wide, oblong-oblanceolate, sharply 

 serrate. Sepals 5, somewhat unecpal, the longest 5 cm. long, 

 1 cm. "wide, 3 or 5-nerved, lanceolate, the setose awn extending 

 3 or 4 mm. beyond the suimnit. Petals about as long as the 

 sepals, linear, acute. Crown apparently single, the fimbriae 1 

 to 1.5 cm. long. Colors not noted. Gynophore nearly 3 cm. long, 

 rather stout. Free portions of filaments 7 mm. long, stout, 

 strongly ribbed. Anther nearly as long as the filament, broad. 

 Styles about 4 mm. long, stout, the stigmas capitate.

Passiflora yacumensis 



Petioles, leaf-veins, etc., sparsely short-pilose. Stems slen- 

 der, elongate, cirrhiferous, lightly sulcate. Tendrils simple, elon- 

 gate, slender. Stipules very small, lanceolate, acute, denticulate. 

 Petioles about 1.5 cm. long, slender, narrowly channeled above, 

 the margins minutely ciliate. Leaves to 7 cm. long and nearly as 

 wide, truncate or subcordate at the base, 3-lobed, occasionally 

 one or both lateral lobes wanting, the margin sharply dentate, 

 with obtuse sinuses ; middle lobe nearly two thirds of the length 

 of the leaf, oval or oblanceolate, the lateral lobes about half as 

 long, lanceolate, moderately spreading, all the lobes acute, the 

 sinuses obtuse; texture somewhat rigid, though thin, 5-nerved, 

 the secondaries of the middle lobe about 5 or 6 on each side, the 

 venation strongly anastomosing, prominent on both sides. Pe- 

 duncle about 4 cm. long, finely angled or sulcate. Bracts 3, about 

 1.5 cm. long, narrowly lanceolate, acute, unequally serrate-den- 

 tate, green, thin. Sepals 5, 4 cm. long, 8 mm. wide at the base, 

 lance-linear, apparently obtuse, the awn 2 mm. long, filiform. 

 Petals 5, 3 cm. long, 3 or 4 mm. wide at the base, linear, obtuse.
