 V. ci.vEREA, var. Florida.na. 



Vitis cinerea -floridana was named by Munson in 1890. It differs from 

 the regular form of Cinerea in having the growing tips and sometimes the 

 veins on the under side of the leaves more or less covered with rusty tomen- 

 tum. The cluster is also longer-peduncled and more compound. It is 

 found in Florida and Arkansas. 



VITIS CINEREA CANESCENS Bailey.

 Syn. FI.. 1:425. 1S07. v. cinerea, var. canescens. 



Vitis cinerea canescens was first mentioned by Engelmann in 1868 

 under the name Vitis aestivalis, var. canescens. He does not describe it 

 further than to say that it approaches Cordifolia. Bailey's determination 

 of its position was made from Engelmann's herbarium specimens. He says: 

 "A form with rounded or heart-like leaves, the upper half of the leaf lack- 

 ing the triangular and 3-lobed shape of the type." This variety has been 

 found in Missouri, Illinois and Texas.
