Left-hand flower 6 mm across

Occasional among wet rocks near where burns enter sea.  Very rare in the north of the region.

Flower diameter c 2-6 cm

ID: Flowers white, 5-petalled, in spikes.  Each flower arises singly from the spike on an up-curved stalk with a small bract halfway along.

Other features: Leaves in a basal rosette looking rather like that of a Daisy, and also up the stem, shiny, slightly fleshy, with rounded tip and narrowing to a stalk-like base.  Small white staminodes between the petal-lobes at top of tube, visible in pic opposite.  True stamens with yellow anthers, further down the tube.  Automatically self-pollinated within the tube.  Fruits globular, enclosed by the calyx whose lobes give a crown-like effect (right-hand edge of bottom pic).
