Fitis tnontieola, Buckley. (Sweel Mountain Grape.) A Blender 

 trailing or climbii reaching 20 to 30 feet in height), 

 with very long and slender branches, the young growth 

 angled and floccose (sometimes glabrous), the diaphragms 

 plane and rather thin: leaves small and thin rarely reaching 

 4 inches in width, and generally from 2 to :; inches high . 

 eordate-ovate to triangular-ovate, with the basal sinus rang- 

 ing from nearly truncate-oblique to normally inverted-U- 

 shaped, rather dark green b above and grayish green 

 below, when young more or less pubescent or even cobwebby 

 below, the blade either prominently notched on either upper 

 margin <>r almost lobed, the point acute and often prolonged, 

 margins irregularly notched with Bmaller teeth than in r. 

 rupestris: clusters Bhort and broad, much branched: berries 

 medium or small (averaging about J^-inch in diameter), 

 black or light colored, seedy, sweet; seed- large (about
