sharply toothed; stipules small: inflorescence ample, loose: berries small, black and 
shining, very acid, ripening after frost: seeds 1.or 2, rather large, with a prominent 
rhaphe.—Thickets and stream-banks. A common stape of the Atlantic States, ex- 
tending into Texas at least as far west as Gillespie County. 
7. V. riparia Michx. (RiVeRSIDE GRAPE.) Differing from the last in the larger 
and more persistent stipules (4 to 6 mm. long), more shining and more usually 3-lobed 
leaves with a broad rounded or truncate sinus and large acute or acuminate teeth, 
smaller compact inflorescence, and berries (8 to 10 mm. broad) with a bloom, sweet 
and very juicy: seeds very small, with indistinct rhaphe.—Stream-banks or near 
water, common in most of the watered cations of western Texas. Berries maturing 
in October. Also known as “ arroyo grape,” 
8. V. rupestris Scheele. (Rock, or SAND, OR SUGAR GRAPE.) Usually low and 
bushy, often without tendrils: leaves rather small, shining, broadly cordate, 
abruptly pointed, with broad coarse teeth, rarely slightly lobed: berries rather 
small, sweet, in very close bunches.—In the valley of Devil’s River and westward 
into the mountains west of the Pecos. Berries ripening in June, Also called 
“mountain grape.” 
2. CISSUS L. 
Like the last, but petals expanding, leaves simple or pinnately com- 
pound, berries with scanty pulp and inedible, flowers in broad flat- 
topped clusters, and tendrils few and mostly in the inflorescence. 
1. C. stans Pers. Nearly glabrous, bushy and rather upright: leaves twice pin- 
nate or ternate, the leaflets cut-toothed: flowers cymose: calyx 5-toothed: disk very 
thick, adherent to the ovary: berries black, obovate. (Vitis bipinnata Torr. & 
Gray.)—Rich soils, extending from the north to central and southern Texas. 
2. C. incisa Desmoul. Glabrous, with climbing warty stem: leaves 3-foliolate, 
very thick and fleshy: the leaflets stalked, wedge-shaped and entire near the base, 
lateral ones 2-lobed, middle one 3-lobed, all mucronate-toothed or serrate: flowers 
cymose: berries purple, globose-ovate. (Vitis incisa Nutt.)—In shady places from 
the Colorado to the Rio Grande and westward. An ornamental vine, known as 
“verba del buey.” 
3. C. Ampelopsis Pers. Nearly glabrous: leaves heart-shaped or truncate at 
the base, coarsely and sharply toothed, acuminate, not lobed: panicle small and 
loose: styleslender: berries bluish or greenish, 1 to 3-seeded, as large as a pea. ( Vitis 
indivisa Willd.)—River-banks, extending from the Southern States to central and 
southern Texas. 
3. AMPELOPSIS Michx. (VIRGINIAN CREEPER. ) 
A woody vine climbing by tendrils that fix themselves to trunks or 
walls by dilated sucker-like disks at their tips, with digitate leaves, 
and cymose flower-clusters. 
1. A. quinquefolia Michx. A common woody vine in low or rich ground, climb- 
ing extensively, sometimes by rootlets as well as by its disk-bearing tenérils: leaflets 
mostly 5 (3 to 7), oblong-lanceolate, sparingly serrate: berries small and blackish, 
ripening in late fall when the leaves turn a bright crimson.—Apparently throughout 
Texas. Also called “American ivy” and “ woodbine.” Blooming the middle or end 
of June. 
2. A. heptaphylla Buckley is very much like the last, but the leaves are all 
6 or 7-foliolate, the leaflets are smaller, subsessile, narrow and shining, few-toothed 
at apex, and the. panicles are smaller, blooming at the end of April. (Vitis hepta- 
phylla Britton.)—Apparently throughout southern and western Texas. Usually con- 
sidered but a form of the last species,
