_ Plant: Climbs vigorously to great height; when young procumbent, slender; 
foliage lively green until very late. 
Roots: Very thick, deeply corrugated bark, moderately firm, penetrating 
deeply, and quite resistant to Phylioxera.

cular, rays numerous, pores small, nodes very large, bulging under and opposite | 
the buds, much bents diaphragm 1/16" (especially in b) to 1/12" or more thick Ht

curved sides which never or rarely lap; a generally 8 to 5 lobed, acute, with 
shallow, narrowly rounded sinuses, often having a convex tooth at base of sinuses,
