'potato-leaf' White Widows photo ...

I have seen references before about a 'potato-leaf' characteristic found on some plants ... my current two Dutch Passion White Widows both have this pheno ... big, round, 'potato' type leaves ... anyone have any info regarding this odd trait ? ... just curious ... :smokin:

All three of my WWs have the long, thinish pucks. About half way between a pure Sativa skinny and a pure Indica fat. Sorry, but this it the first time I've seen a WW with such fat pucks. Wish I could help.
