 peduncles simple or in pairs, shorter than the leaves, naked : sepals oblong or linear-ob- 

 long, 8-12 mm. long : corolla greenish yellow, about 2 cm. broad : petals similar to the 

 sepals in shape : crown of 3 series of filaments : berries subglobose or oval, 1-1.5 cm. in 

 diameter, purple, glabrous. 



In woods and thickets, Pennsylvania to Missouri, Florida and Louisiana. Spring and summer. 



4. Passiflora affinis Engelm. A glabrous high-climbing vine, with slender tendrils, 

 the stems angled. Leaf-blades 5-10 cm. broad, 3-lobed, glaucous beneath, the lower cor- 

 date, the upper truncate or acutish at the base, lobes obovate or oblong, nearly equal, entire, 

 setaceous-mucronate ; petioles without glands : stipules setaceous : peduncles 3-6 cm. long, 

 with 2 or 3 setaceous bractlets : sepals 1.5 cm. long : corolla 3-3.5' cm. broad : petals obtuse, 

 shorter and narrower than the sepals, yellowish : crown with fringe about as long as the 

 sepals : berries subglobose, about 12 mm. in diameter, bluish black, the stipe as long as the 

 diameter of the berry. 



In valleys, from the Colorado River to the Rio Grande, Texas. Summer and fall. 



5. Passiflora inamoeiia A. Gray. A reclining or climbing vine 3-9 dm. long, with 

 hirsute foliage, the hairs barbed. Leaf-blades very thin, 8-12 cm. in diameter, deeply 

 3-lobed, usually cordate ; lobes oblong to oblong-elliptic or oval, irregularly toothed, or the 

 lateral ones sometimes lobed ; petioles each with 2 glands near the apex : peduncles shorter 

 than the petioles, with several setaceous bractlets : sepals triangular-lanceolate, 10-14 mm. 

 long, green : corolla greenish, 2.5-3 cm. broad : berries ovoid or elliptic-ovoid, 3-3.5 cm. 

 long, the stipe not surpassing the persistent calyx. 



In valleys, Texas to New Mexico and adjacent Mexico. Spring to fall. 



6. Passiflora suberosa L. A climbing vine, with nearly glabrous foliage. Leaf-blades 

 ovate in outline, 6-15 cm. long, ciliate, 5-nerved at the broadly cuneate or cordate base, 

 3-lobed to above the middle ; lobes ovate or triangular, acute or acuminate, the middle one 

 much the larger ; petioles 5-15 mm. long, each with 2 glands at or above the middle : 

 peduncles surpassing the petioles, commonly in pairs : calyx greenish, 2-2.5 cm. broad : 

 sepals lanceolate or linear-lanceolate, 8-12 mm. long : corolla wanting : crown-filaments 

 purple at the base, shorter than the sepals : berries subglobose or oval, 10-12 mm. in 

 diameter.
