The presence of stipules on many of the petioles of the variety suggests 



& 



species have a 



very different fruit with a much flattened stone showing two lateral grooves 

 on the ventral side, while this variety agrees exactly in its fruit with the 

 type of V. pubescens Pursh {V. venosum Britt.) which has a globose conical 

 or short ellipsoidal scarcely or slightly compressed stone with a deep 

 groove in the middle of the ventral side. In typical V. pubescens and in 

 its varieties, var. Canbyi Blake and var. hngifolium Blake, the petioles 

 are almost always without stipules, but may be occasionally stipulate on 

 any of these three varieties, therefore it does not seem advisable to con- 

 sider the greater or lesser prevalence of stipules a character of sufficient 

 value to separate this and the following variety specifically from V. pu- 

 bescens. In the size and shape of its leaves, at least in its typical form, var. 

 Deamii has some resemblance to V. molle, but in that species the leaves are 

 distinctly cordate at base, the branchlets are light gray or light grayish 

 yellow and the bark on older branches separates in thin flakes. It also 

 resembles V. pubescens var. Canbyi Blake which, however, has somewhat 

 smaller and narrower leaves with fewer veins and glabrescent beneath 

 and pubescent branchlets, though occasionally the under side of the leaves 

 may be more pubescent as in a specimen from Wayncsville, N. C. (Bilt-
