	Action: changed name from "Pediocactus simpsonii var. robustior" to "Pediocactus simpsonii var. nigrispinus "
	Reviewer's comments:
	"There is no P. s. var. robustior growing in WA. The real var. robustior is growing in NV! All the other photos from WA called var. robustior should be also changed to var. nigrispinus."
