Just need to know from people who live in the particular states where these cacti grow (That look vary similar) what the difference is, call it scientific curiosity or indeed inquiring minds need to know and all that: or as Mr. Eldon Tyrell put it "Indulge me". Think on this an idea remains just an idea until basic knowledge turns that idea into theory, a theory remains a theory until accurate (Repeatable) experimentation, and verifiable data (Ideally tested with the double blind method to exclude bias) turns theory into a hypothesis which in turn remains just that until proved or not as fact, this then is the nature of science I have at this time the kernel of an idea; I asked so that I may either move forward or not and forget the whole thing, and chalk it up as another bad experience.
In the end then I ask things like this because I can not stand wasted time in any portion of my life, weather that be in my on-line or off-line life; one of the key lesions I have learned form many sources including people I've meet, books, history, school and else where is that if there is some thing you don't know find some one or several some one's who do and ask; you can then get the information you require and you can get on with you day. Think of it this way, Imagen a line of traffic and some thing happens at the head of the line say some one has a flat or touches the brakes what you get is a ripple effect down the line, which causes slow downs or even jams ; once the front of the line gets moving again it takes a while for that line of traffic to start flowing smoothly again: same thing with information if you don't have what you require at the time that cuts into you efficacy and productivity during the day causing you to be behind, this I do not like...At all.
So with the foregone iconoclast out of the way and for the sake of been irreverent a few pointers to the required data will as you fine people from the union say..."Be Real Swell".
I here by close and humbly thank you for your assistance in these matters.
Regards to you.
