Series IV. Viniferae, Munson 



(A) V. VINIFERA, L. (Plate XVII.) 



Although this species is largely cultivated in California, Mexico, and some other parts of 

 America, it is an exotic from Asia, and is so well known and has been so well treated by numerous 

 authors, that I can add nothing of value in treating it as a species. I mention it here merely 

 to indicate where it would find its proper relationship as nearly as possible in our scheme of 

 classification. 



(B) VITIS BOURQUINIANA, Munson. (See Plate XVIII.) 

 Synonym: 



\'itis ccatii'alis, Engelmann, Bushberg Cat. 7, p. 16, 1SS3. 



"Southern /Estivalis." 



Two forms; a such as Herbemont, Lenoir, etc., with distinctly lobed leaves and mostly ' 

 compound clusters; and b with leaves only shouldered, each side the mid-lobe or top, and clus 

 simple such as Devereux, Rulander, etc. 



Plant. Climbs vigorously to great height; when young procumbent, slender; foliage Ir 

 green until very late. 



Roots: Very thick, deeply corrugated bark, moderately firm, penetrating deeply, and quite 

 resistant to Phylloxera. 



Wood: When young, green or pale red, smooth or with scattered hairs, cylindrical ; bark of 

 a pale cinnamon or reddish-brown color at maturity, obscurely striated, fibrous, true bark finely 

 checked above ground, mature annual wood, with a little prunose bloom about the nodes, and 

 often a fine bristly, or short brown plush-like pubescence, as in Herbemont, is near the nodes; 

 persistent; wood of medium density, more in a than in b; sectional view of annual wood oval 

 or circular, rays numerous, pores small, nodes very large, bulged under and opposite the buds, 

 much bent; diaphragm 1/16' (especially in b) to 1/12' or more thick (in a), slightly biconcave, 

 less in b than in a, buds in a very broad at base, similar to Vinifera, globose, conical, covered 

 with pale brown scales, or in b, smaller, more conical and acute, with darker scales, large rusty 

 pink in expanding; tendrils often twice forked in a, less so in b, long and strong in a, less so in b; 

 internodes short, I' to 3' or more, long; pith rather small, a little enlarged at lower end, light 

 brown. 



Leaves: Stipules small, short and broad, pale, thinly hairy; petiole half as long as width of 

 blade, or less; generally cylindrical, obscurely striated and grooved, thinly or often densely 

 pubescent in a; blade largest in a, 4' to 6' or more wide by 3^' to 5^/o' or more in length; in b 

 .'>' -i to 43/2' or more wide by 2]4' to 3J^' or more long; outline of blade in the Warren, group a, 

 broad cordate, in the Devereux, group b, circular; basal sinus deep, acutely A shaped with curved 

 sides which never or rarely lap; a generally 3 to 5 lobed, acute, with shallow, narrowly rounded 

 sinuses, often having a convex tooth at base of sinuses, apex acute; b broad, obtuse, shouldered, 

 apex broad, short, acute; teeth in both a and b distinctly raised, convex mucronate, with a yel- 

 lowish-white mucron, notch between teeth acute; venation prominent from the thinly hairy or 

 pubescent, sometimes 6 to generally 7 pairs of nearly opposite ribs, in the forks of which small 

 pubescent tufts are rarely found; young leaves in buds just expanding, pale green or pinkish, 

 later whitish on both sides with silky white wool, never rusty, soon becoming smooth above and 

 a little wrinkled, of a clear, lively dark green color, much paler beneath; texture dense. In a 

 first true leaves small, ovate-acute, green; first year often lobed; in b first true leaves larger, 

 green; on seedlings first year rarely lobed. 



Cluster: In a medium to large, simple or compound, usually compact, heavily shouldered, 

 with a false tendril on peduncle, as in V. azstivalis and V. cinerea; rachis smooth; pedicels 

 very variable, in Herbemont and many of its seedlings, thick, enlarging upward, more slender 

 in Jacquez and Devereux ; enlarging towards receptacle, very warty in a, less so in b.
