It's also very possible that the outside was darkened in post. The light might be from a twin-light flash where you can aim the lights more precisely. http://www.bhphotovideo.com/c/product/239656-USA/Canon_2357A002_MT_24EX_Macro_Twin_Lite.html
Do you know how the image was made? It looks to me a lot like some of the flower images created by Katinka Matson. They're gorgeous, but they're not photographs -- the flowers are arranged on a flatbed scanner and scanned. The way the light falls off quickly and uniformly around the flower looks a lot like what you see in Matson's work.
To hazzard a guess, I would say that the lighting was done with a twin-tube affair, with the tubes arranged above and below the lens. The upper tube was the main (more powerful) light; the lower tube was fill at about half the upper tube's power (down 1 stop, or a 1:2 ratio with the "A" tube at the top). To get the fall-off you see from front to back, the ...
The key changes that I see immediately are: White balance (slightly warm) Black levels (quite high) Faux cross-processing (Red s-curve, Blue upside down s-curve, slightly higher green lows) Vignetting That should get you close.
I'd say maybe try a gradient map layer with a dark gray as the lower colour and an average green-yellow (or pink-red for some pictures, like the two leftmost ones) as the upper colour, then play with the opacity, maybe 10 to 20%. I'm not able to check right now, I'll try it later and update the answer with more precise values.
