Another alternative would be "number of axes."   I also find a
glossary used by the J language (an APL descendant) useful in array
discussions. See
<http://www.jsoftware.com/books/help/jforc/glossary.htm>.

Here is how J documentation explains the difference in their
terminology and that of the C language: "What C calls an n-dimensional
array of rank i×j×…×k is in J an array of rank n with axes of length
i,j,…,k."  <http://www.jsoftware.com/books/help/jforc/declarations.htm>
