VITIS BLANCOII 
Vitis blancoii, Munson 
Synonyms: 
| V. Caribsea, Harvard Herbarium, Dr. E. Palmer, 1886. 
Vine: Vigorous, climbing very high, foliage presenting a pale grayish~ 
green aspect, in dense canopy on small trees. 
Roots: Wiry, penetrating very deeply. 
Wood: Growing tips extending rapidly beyond the slowly enlarging leaves, 
densely whitish, or pale rusty wooly, which wool persists during the first year; 
at first, wood is slightly angled,but becomes smooth cylindrical with maturity, 
pale dull green at first, very dark, reddish brown at maturity; outer bark sheds 
the second year slowly in narrow fibrous plates, leaving the true bark rough 
pale brown, which with age becomes finely divided lengthwise, as in V. cinerea, 
butpf a darker color; wood rather soft, tough and uncommonly flexible; inter-— 
nodes 5" to 6" or more long in well grown canes, pith light brown, somewhat 
greater in diameter than the thickness of mature annual wood from pith outward, 
expanding and abruptly terminating above, but gradually below the diaphragm, 
which is about 1/16" thick, cross section of wood very porous; nodes little 
enlarged, or bent, stipular ridge not very prominent, and extending about half 
way around to base of tendril, then curving downward; tendrils 2" to 5" to fork, 
mostly bifid, white tomentose, very strong; buds small, at first subglobose, 
becoming at full maturity slightly triangular, but remaining blunt at apex, 
covered with dark brown scales, and rusty wooly at summit, inunfolding whitish or 
pale pink, tip closed. 
Leaves: Stipules very small, rusty wooly; petiole 1" to 2" long, cylindrical, 
with distinct narrow groove @long upper side, of uniform thickness the entire 
length, densely whitish wooly;blade long-cordate, entire, when fully grown 3" to 
4" wide, with midrib 4" to 5" long; basal sinus inverted U or cupid's bow shaped 
(which is quite different from other species of this series, except sometimes the 
inverted U shape i& found in V. Berlandiari; margin rarely slightly lobed or 
shouldered and finely tao the)) Ltn sharp, mostly erect short teeth with a distinct 
mucron; apex generally very—tHong taper—pointed; venation from the mostly 8 pairs 
of generally alternate ribs very depressed, and obscured above by thin cottony 
wool, and below by dense whitish, or ash-colored felt; Zpper face at full maturity 
bearing flocculent cotton along the ribs, giving foliage grayish aspect, elsewhere 
being a dark dull green with little or no wrinkling. 
Clusters Fertile, of medium size, 5" to 5" long; simple, with a shoulder 
or but little compounded, pedicels 2/16'to 3/16" long, slender, scatteringly 
warty, slightly enlarged at apex; staminate,- cluster somewhat larger. 
Flowers: Very small and slender in all its parts. 
Berries: Small +" to 1/3" in diameter, spherical, black, with thin bloom 
when ripe; skin thin, tough, not pungent, pulp juicy, pure sweet, vinous,
