Field Book — Heide Pretorius

Green and white A page from the field book: what opened after the first good rain.

Pink, six ways Six species that all flowered on the same slope in the same week.

Spergularia on the salt ground Two centimetres across. The succulent stems around it are salt bush, which turns red towards summer.

Blue lobelia in the sour grass A clump that returns to the same spot every year, on the south side of the stone ridge.

Yellow button among the vygies Cotula turbinata, the only one open on an overcast August morning. The vygies around it were still closed.

Nudibranch in the tidal pool I lay on my stomach for twenty minutes for this one — it kept moving in under the lip of the rock.
