New cholla growth

The green spikes behind the new spines are rubbery. They are not present on older growth. I wonder what their purpose is. A Finger-leaved Gourd up at the north end, with a flower and a gourd on it. The White-thorn Acacias a showing some flowers, bright yellow puffballs, quite different from the creamy catkins of the Catclaw Acacia.
