Veronica jovellanoides

Veronica jovellanoides, commonly known as Riverhead speedwell, is a threatened flowering plant in the family Plantaginaceae. It is endemic to New Zealand, where only three plants are known in the wild. All are found within the Ernest Morgan Reserve, a 20 ha forest northwest of Auckland. Its discovery is accredited to a retired plant nursery owner, Geoff Davidson, who organised the land's protection a few decades prior, and found it by chance on a walk in November 2007. V. jovellanoides has a prostrate growth habit, forming large 2 to 3 m (6.6 to 9.8 ft) mats on the ground, and long stems with small, spatula-shaped leaves. Flowering begins in spring (September to November in New Zealand), producing small four-petalled white flowers which have a purple ring around their throats; the inner and centre-most section of the flower. Once pollinated, these become small brown seeds which are dispersed by the wind....read more on Wikipedia.
