 scales (particularly on the veins), smooth above, the margin crenulate or entire : petiole 

 somewhat margined ; cymes pedunculate ; fruit ovoid. — Torr. <^ Gr. Jl. N. Am. 2. p. 14. 



var. 1 . Claytoni : leaves broadly oval, oblong-obovate or oblong, somewhat shining above, 

 obtuse or slightly acuminate, entire or obscurely crenulate, slightly revolute on the margin, 

 the veins rather prominent underneath ; cyme on a long peduncle. Torr. ^ Gr. /. c. V. 

 nudum, Linn. sp. 1. p. 268 ; Michx. Jl. I. p. 178 ; Bot. mag. t. 2281 ; Ell. sk. 1. p. 375 ;

var. 2. cassinoides : leaves ovate, slightly obovate or oblong, dull above, often abruptly 

 acuminate, the margins crenate-serrate or undulate, the veins not prominent underneath; 

 cyme on a short peduncle. Torr. <^ Gr. I. c. V. cassinoides, Linn. sp. ed. 2. p. 384 ; Pursh,

 <^c. V. squamatum, Willd. enum. 1. p. 327. 



Stem 6-12 feet high, slender, branching. Leaves 2-4 inches long, thickly sprinkled 

 with minute bran-like scales underneath, sparingly dotted above ; mostly entire on the margin, 

 attenuate at the base, and rather obtuse, in the first variety ; more or less crenate-serrate 

 (sometimes rather acutely), acute but not attenuate at the base, and rather conspicuously 

 acuminate, in the second. Cyme 2 - 2J inches in diameter ; the peduncle often two inches 

 long in the former var., less than an inch and often nearly sessile in the latter. Fruit about 

 one-third of an inch long, ovoid, abruptly pointed, slightly compressed, dark blue, with a 

 glaucous bloom. Nucleus or stone much compressed, slightly convex on one side and a 

 shallow groove on the other. 



Swamps : the first variety common in the northern and western parts of the State, but not 

 found south of Hudson ; the other in the neighborhood of New- York, and I think also in the 

 cedar swamps of Long Island. Fl. May - June. Fr. September. 



Many botanists consider the V. cassinoides, Linn, (pyrifolium, Pursh, <^c.), a distinct 

 species from V. nudum, but there are intermediate forms that seem to connect them.

 slight abrupt point, finely serrate with appressed or uncinate teeth, smooth ; petiole with a 

 very narrow and even margin ; cymes sessile or nearly so ; fruit oblong-ovoid. — Linn. sp. 1.
