epidermal long cell definition

[kellogge]

I think this was one of those "wait-until-we-need-it" terms.  Grass  
epidermes have long cells and short cells in the epidermis, so we  
should probably introduce both terms.  They will be children of  
"epidermal cell".

"long cell" = a more or less rectangular epidermal cell in which the  
the proximo-distal dimension is several times longer than the  
transverse dimension

"short cell" = an isodiametric epidermal cell

"epidermal cork cell" is an instance of "short cell"

Comment (for both cell types): In the leaf epidermis of Poaceae and  
Joinvilleaceae, long cells and short cells often alternate in  
longitudinal rows.
