3. S. glauca, Walt. Terete branches and somewhat 4-angular branchlets 

 armed with scattered stout prickles, or naked ; leaves ovate, rarely subcordate,

t- •<- i- Peduncles 2 -4 times the length of the petiole: leaves ample (3' -5' long), 

 thin or thinnish, green both sides : berries black : stem terete and branchlets nearly so. 



5. S. hispida, Muhl. Eootstock cylindrical, elongated ; stem (climbing 

 high) below densely beset with long and weak blackish bristly prickles, the flowering
