Some of them are as follows: Walter says “foliis oblongo-cordatis”; Wood, “ovate, finally nearly orbicular, abruptly contracted at one end”; Gray, “ovate, rarely subcordate, abruptly mucronate”; Britton, “ovate, acute or cuspidate at the apex, sometimes cordate at the base.” I would suggest the following as applicable to the Ohio specimens: Leaves _mostly ovate, often broadly oval (occasionally broader than long), sometimes oblong-ovate, varying to lanceolate or even linear; the base mostly subcordate but often cordate or even cuneate; the apex cuspidate to acute or sub-acuminate_. SMILAX SPINULOSA.—Britton and Brown in the illustrated Flora, 1:440, appends to the description of Smilax glauca the following paragraph: “Smilax spinulosa J. E. Smith, is a form with numerous small prickles on the lower part of the stem, and more elongated, sometimes halberd-shaped leaves. It occurs in southern New York, but is not well understood.” However Smilax spinulosa is given by these authors as a synonym of Smilax glauca, which according to my judgment is correct.
