the base to the disk. Style slender. Ovules 2 in each cavity. Berries with scant pulp 
or nearly dry, inedible. Seeds;2-4, somewhat 3-angled. 
Leaf-blades simple: ovary not surpassing the disk but nearly free from it. 1. A. cordata. 
Leaf-blades bipinnate: ovary surpassing the disk, the latter mostly adnate to it. 2. A. arborea. 
1. Ampelopsis cordàta Michx. A high climbing vine, with forking tendrils and a 
warty bark. Leaf-blades simple, ovate or triangular-ovate, 4-12 cm. long, acuminate, shal- 
lowly, but acutely, serrate, glabrous or sparingly pubescent about the nerves and their axils 
beneath, truncate or piel sees at the base ; petioles shorter than the blades, often pubes- 
cent: cymes slender-peduncled, 3-8 cm. broad : disk cup-shaped, as high as the ovary but 
nearly free from it: style slender: berries subglobose, 6-8 mm. in diameter, insipid, 
bluish or greenish blue: seeds 1-3, about 5 mm. in diameter, nearly as broad as long, 
granular, the raphe indistinct. [Cissus Ampelopsis Pers. ]

fruit ripening in summer and fall. 
2. Ampelopsis arbórea (L.) Rusby. A stout climber, with few forking tendrils, the 
stems sometimes very long. Leaf-blades bipinnate, 1-2 dm. long, petioled : leaflets several 
or many, the blades ovate, often broadly so or cuneate-obovate, 1-3 cm. long, acute or 
acuminate, coarsely toothed, incised or lobed, glabrous or sparingly pubescent, sessile: 
cymes long-peduncled but shorter than the leaves: disk scandal by the ovary, mainly 
adnate to it : styles conic-subulate : berries subglobose, 10-13 mm. in diameter, dark purple: 
seeds 2-4, 4.5-5 mm. long, granular, each with a conspicuous raphe. [Cissus bipinnata 
(Michx.) Nutt. ] 
In low places or swamps, Virginia to Missouri, Florida and Texas. Also in the West Indies and 
Mexico. Spring to fall; fruit ripening in the fall. PEPPER-VINE. 
5. PARTHENOCISSUS Pianch. 
Trailing or climbing vines, with forking tendrils, whose tips often bear adhering disks, 
or are merely coiling. Leaves alternate: blades digitately 5-7-foliolate : leaflets entire or 
toothed. Flowers perfect or polygamo-monoecious, in compound cymes. Calyx pedi- 
celled. Petals 5, expanding, often fugacious. Disk obsolete or wanting. Stamens 5 
Ovary 2-celled, sessile: style stout. Ovules 2 in each cavity. Berries with scant pulp, in- 
edible. Seeds 3-angled. VIRGINIA CREEPER. AMERICAN Ivy. 
Foliage pubescent, usually densely so. 1. P. hirsutus. 
a blades b 6-foliolate Alleghenian and tri i 
Tendrils with disks: ieat-biades with appressed, at least not flaring, teeth. 2. P. quinquefolia. 
Tendrils without disks: leaf-blades with flaring teeth. 8. P. laciniata. 
Leaf-blades 7-foliolate: Texan species. x 4. P. heptaphylla. 
1. Parthenocissus hirsütus (Donn.) Small A spreading vine, with pubescent mum 
leaves and inflorescence, and slender tendrils, the stems trailing. Leaflets 5, the blades 
oval, elliptic, oblong or ovate, acute or short-acuminate, coarsely toothed above the middle, 
all except the terminal one, inequilateral: corymbs 8-12 em. broad: berries sub lobose, 
dark blue, with a slight bloom, slightly pulpy: seeds 5 mm. long, glossy, notched at the 
top, with a conspicuous spatulate raphe. [Ampelopsis hirsutus Done] 
In rocky places, Georgia to Texas and Mexico. Spring; fruit ripening in August and September. 
. 2. Parthenocissus quinquefólia (L.) Planch. A high-climbing or sometimes trail- 
ing vine, with stout tendrils which adhere by disks. Leaflets 5, the blades usually d 
nish, oval, elliptic or oblong, the lateral ones inequilateral, coarsely serrate above P : 
middle with rather appressed or at least not flaring teeth, short-petioluled : corymbs 8- 
em. broad: berries subglobose, 8-9 mm. in diameter, deep blue with a scant bloom, often 
quite pulpy : seeds 4-4.5 mm. long, prominently rugose, rather dull, each with an orbicular
