1. VITIS Tourn. (GRAPE.) 
Plants climbing by the coiling of naked-tipped tendrils, with simple 
rounded and heart-shaped leaves, a compound thyrsus of very fragrant 
flowers, small green petals which cohere at the top and fall off together 
without expanding, and a pulpy berry with pyriform seeds beak-like at 
base.—We have not attempted to follow Planchon’s presentation of our 
grape-vines, but give that of Engelmann, from the Bushberg Catalogue 
of 1883. Our species are all true grape-vines, with loose shreddy bark, 
climbing by the aid of forked tendrils, or sometimes almost without 
tendrils. The seed characters are quite important. 
* Leaves pubescent or floccose, especially on the under side and when young, often becoming 
glabrous with age. 
+ Rhaphe on seed indistinct. 
1. V. candicans Engelm. (Musrane GRAPE.) Tall climber, with rather large 
rounded almost toothless leaves, on young shoots usually deeply many-lobed, deep 
green above and white cottony beneath: berries large, greenish, claret, or bluish- 
black.—Along streams from the Colorado to the Rio Grande and west to the Pecos. 
Said to be the best of the wild grapes of Texas, maturing late in June. 
2, V. monticola Buckley. (MOUNTAIN GRAPE.) Usually a small bushy vine, 
rarely climbing over high trees, with angled branchlets: young steins, petioles 
and leaves cottony, downy, the down gradually disappearing, remaining only here 
and tbere in floccose bunches: leaves deeply cordate, with a rounded sinus, very 
shortly 3-lobed, with small but broad teeth, older ones very smooth and often con- 
spicuously shining below, usually small, not more than 7.5 to 10 em. across: 
bunches of fruit compact and short: berries 8 to 10 mm, in diameter. (V. estivalis, 
var. monticola Eng. V. Berlandieri Planchon.)—Peculiar to the hilly limestone 
region of western Texas, not extending to the low country nor to the granitic 
mountains. Common about Austin, New Braunfels, San Antonio, etc. 
3. VW. Arizonica Engelm. (ARIZONA GRAPE.) Closely related to the last, with 
angular branchlets: leaves cordate, with a rather open rcunded sinus, not lobed (or 
with 2 short latent lobes); when young, floccose, cottony; when older, glabrous, 
thick, very rigid and (especially upper surface) rough: berries sinall or middle- 
sized, —An Arizona species that extends into western Texas, being found in Gillespie 
County. Said to trail over rocks and bushes. 
+ + Rhaphe on back of seed very conspicuous, 
4. V. estivalis Michx. (SuMMER GRaPE.) Branchlets terete: leaves large, entire 
or more or less deeply and obtusely 3 to 5-lobed, with short broad teeth, very woolly 
and mostly red and rusty when young: berries middle-sized, black with a bloom, in 
compact bunches.—A grape-vine of the Atlantic and Gulf States and extending into 
Texas to the Pecos. Usually on uplands in dry open woods or thickets. Abound- 
ing in the sandy post-oak woods of eastern Texas it is called “ post-oak grape” or 
‘‘sand-grape.” Ripening in September. 
5. V.cinerea Engelm. (DOWNY GRAPE.) Branchlets angular: pubescence whitish 
or grayish, persistent : leaves entire or slightly 3-lobed: inflorescence large and 
loose: berries small, black without bloom. (V. estivalis, var? cinerea Eng.)—In rich 
bottom lands, eastern and southern Texas, from Arkansas to the Rio Grande, com- 
moner northward. 
** Leaves glabrous, or sometimes short-hairy, especially the ribs beneath, mostly shining. 
6. V. cordifolia Michx. (FROST OR CHICKEN GRAPE.) Leaves 7.5 to 10 em. wide, 
not lobed or slightly 3-lobed, cordate with a deep acute sinus, acuminate, coarsely and
