But now that my pots have filled in completely, the two look different. My N. dialystemon has leaves that, while narrow, are twice as wide as those of my N. sellowianum. Lee ~ Wouldn't that be the sort of variation that one would expect when dealing with species? Although, if these things don't readily set seed, than what we may be dealing with are clonal forms that are/were (unintentionally?) distributed as such and under different names. One fallout, I suppose, of botanists/classifiers, etc., who keep changing the name of plants that don't know they aren't supposed to be different!
