some solanum morphology

mostly because it's my blog...the first photo is of a bloom on a blue shetland potato plant...the second is carolina horse nettle...the third is blue shetalnd leaves and the fourth carolina horse nettle...i would suppose that the blue shetland is a less "improved" variety of spud mostly because it resembles the wild solanum plant reasonably closely...

this red pontiac at the community garden is an "improved" variety that is grown commercially...it has broader leaves that almost completely lack the rounded serrations on the other two plant's leaves...and, since it's my blog, you didn't think you were getting away without seeing some teosinte, did you?
