Dyckia delicata looking delicate....and white.
These new found beauties are smaller and much whiter than those we know.
I just visited twice, recently, its local and found out five different occorencies! Five! I have local testemonies of more..... I must get bach there soon after this new cold wave here. 
It is colll...llld today, here and there too!
 I´ve heard, locally, of delicatas no larger than a child´s hand, some as red as fire and as white as snow. Of course these are comments and reports based on no scientific observation and made by local and quite rudimentar settlers. They speak a kind of funny Portuguesse. These reports are impressive and must be investigated.
