medium, broadly cordate, generally cupping toward lower face; basal 

 sinus A-shaped or wanting, with truncate base; surface slightly rugose, 

 dark green, thick, leathery; young leaves at first appearance pale pink- 

 ish, lower face covered with whitish or rusty tomentum, except in V. 

 Champini thinly tomentose or pubescent. 



Cluster: small, loose, simple, or forked; peduncle medium ; pedicels 

 short, thick. 



Berries: medium to very large, without bloom, very persistent; sMn 

 thick, more or less pungent, not musky or "foxy, pulpy." 



Seeds: chalaza and raphe depressed. 



Germination, foliation, inflorescence, ripening of fruit, early to me- 

 dium, enduring great drought and little cold; cuttings rooting poorly 

 in V. candicans and V. coriacea, but easily in V. Champini; resistant 

 to phylloxera; natively found chiefly on limy soils.

Series 4. Labruscae, Planchon. 



Vine: strong, stocky, climbing well; tips of growing shoots little en- 

 veloped in rapidly growing and unfolding leaves; seedlings first year 

 feeble, declining. 



Roots: one year seedlings non-axial and enlarging downward, little 

 or scarcely tapering, transversely wrinkled, not fully resistant to phyl- 

 loxera. 



Wood: young, densely tomentose, often bearing stiff spinous pubes- 

 cence, cylindrical; annual, mature, reddish brown; diaphragm medium 

 thick, bi- concave; buds medium broad, sub-triangular, with acute sum- 

 mit; tendrils continuous, bifid or trifid, strong. 



Leaves: at first rosy pink, densely tomentose; stipules long-cordate 

 or lance shaped, thinly tomentose; blade large, broad cordate, plane or 

 cupping toward upper face; basal sinus narrowly A-shaped or lobes 

 lapping; upper face rugose, dark green; lower face densely whitish or 

 rusty woolly. 



Clusters : small to medium, compact, simple or shouldered; pedicels 

 thick ; peduncle short to medium. 



Berries: medium to large, covered with pru nose bloom, musky ( u foxy") 

 in odor and taste, pulpy; little persistent after ripening. 



Seeds : chalaza and raphe sunken or obscure, upper end notched. 



Germination, foliation, inflorescence, and ripening of fruit early to 

 medium; cuttings growing easily; natural habitat, moist, loamy, sandy 

 soil.
