Thanks Hadley for your comment.  I've got a minimum of 12 species and 
thus just using different greys won't do it.  I've tried it with two 
background fills, i.e. white and a medium grey, and then used various 
angles for the shading lines, even plotted it twice to obtain some sort 
of cross shading.  For good, distinguishable patterns I've been hoping 
to be able to fill an area with different symbols.
