Calochortus invenustus

Can someone please explain disjunct population dynamics to me? Like how does a species end up growing in the Bay area, and also in the far South of California with a population appearing for some reason in the Bodie Hills of Nevada? Yet not having a contiguous range even though the habitat of sagebrush, chaparral and fir woodlands  extend throughout the region. Is it a predation thing? Maybe a soil/fungal interaction that doesn't exist throughout?  A soil type? Rock underlying base? I could spend a lot of time hypothesizing but for some reason no one puts any money behind research into something I find so fascinating.

Or at least i'm assuming this is actually invenustus, with the strange population dynamics, and this form having unusually blue anthers as well as a blue shaft on it's trifid stigma. This one is said to be somewhat intractable in cultivation and hard to grow outside of it's native range. Ha! outside of it's strangely disjunct native range? I guess if you can recreate the conditions of the  bay area, and San Diego and a low range in Mono County complete with ghost towns and abandoned gold mines then  you can probably grow this flower.

For some reason they call it the the plain mariposa but it is anything but.

I am really excited to be able to photograph these with a great lens finally, I picked up a smoking deal on a dirt cheap 30mm F3.5 sony lens that I'm gonna use for the backpacking I plan to do into the wildlands at somepoint and If all goes according to my well laid plans, I'm gonna pick up that 90mm F2.8 macro Sony makes and then I'm gonna start taking the best pics ever!

Cheers,
