DESCRIPTION:In 1901 Severi proved the complex quadric Veronese variety is 
 determined by three algebraic/differential geometric properties. In 1984 M
 azzocca and Melone  obtained a combinatorial analogue of this result for f
 inite quadric Veronese varieties. We make further abstraction of these pro
 perties to characterize Veronesean representations of all the Moufang proj
 ective planes defined over a quadratic alternative division algebra over a
 n arbitrary field. In the process\, new Veroneseans over a non-perfect fie
 ld of characteristic 2 (related to purely inseparable field extensions) ar
 e found.
