General Species Information:
Found in the Adelaide Hills, Coastal Areas and possibly elsewhere
These little bushes are a ray of sunshine in spring
The flowers drop their petals very easily, leaving discussion and quandry in their wake as one tries to work out this new green flowering plant
The yellow flowers are ~15mm wide, with the pale green buds at just over 2mm.
The flowers can vary in general appearance with the 5 petals being close together forming a buttercup flower appearance, or spread apart looking like a star.
Counting the petals isn't easy with petals often overlapping, yet each one having an indent in the end making it appear to be 2 petals close together.
The green, nearly cylindrical leaves have a sharp spike on the end (hence prickly) and are ~8mm long. They are adjacent, often in swirls of 5 leaves (ie about 70 deg apart), with fine teeth along the edge.
