Yes! Dyckia and unknown.
Big and yellowish this southern species is mostly unknown.
It never bloomed here in my garden and I am still to see its flowers.
In nature most of the individuals are darker and greener but some are deep yellow and these yellow individuals are not  suffering form to much sun exposition nor  lack of food and also they are so year around. Some Dyckia species present this xantochromic individuals and I have seen this in nature among  Dyckia brevifolia, distachia and this one unnamed species. They are no doubt impressive plants. I also notice this plants are easier sun burned than the dark ones.
