Definition by Fahn A suggests

Epithem: Mesophyll of a hydathode concerned with the secretion of water

Epithelium: A compact layer of cells often secretory in function, 
covering a free surface or lining a cavity.

based on this Epithelium cells do qualify. I am not so sure about 
Epithem cells, because they are just part of the epithem tissue lying 
between the vein ending and the pore of the hydathode.
