6. Viburnum mdlle Michx. A small branching shrub, 2-4 m. tall, with more or less 

 stellate-pubescent foliage. Leaf-blades suborbicular, broadly ovate or rarely elliptic, 3-14 

 cm. long, commonly short-acuminate, obtuse or acute, crenate-dentate or the teeth some- 

 times acute, rounded, truncate or cordate at the base, glabrous or sparingly pubescent

7. Viburnum cassinoides L. A slender branched shrub or small tree, 2-5 m. tall, 

 with very scurfy twigs, petioles and inflorescence. Leaf-blades thickish, ovate-elliptic, 

 ovate-lanceolate or oblanceolate, mostly abruptly acuminate but rather obtuse, undulate or 

 crenate, cuneate or rounded at the base, glabrous or glabrate above, mostly scurfy on the 

 nerves beneath : petioles 1-2 cm. long : cymes 5-12 cm. broad, longer than the peduncles : 

 flowers all perfect : corolla white, 4-5 mm. broad : drupes deep blue or rarely pink at 

 maturity, ovoid or globose-ovoid, 6-9 nun. long ; stone flattened. 



In swamps or wet thickets, Newfoundland to Manitoba and Florida. Spring to fall. Withe-rod. 



8. Viburnum nudum L. An erect branching shrub, 1-4 m. tall, with obscurely 

 scurfy and pubescent twigs, petioles and inflorescence. Leaf-blades leathery, oval, ovate, 

 oblong, broadly lanceolate or oblanceolate, 5-15 cm. long, acute or obtuse, slightly revolute,

 ing from North Carolina to Florida and Louisiana, with linear-oblong or narrowly oblong-lanceolate 

 leaf-blades, is V. nudum nnf/ustifoUum T. & G., while a little-known form from near Darien, Georgia, V.
