perennial with forked stems, opposite uniform leaves, and 

 small pale red flowers, marked with a circle of white at the 

 base of the petals. It is a native of New Zealand, intro-

 a perennial succulent root, with bipinnatified leaves, and 

 large yellow flowers. A beautiful and rare plant, rather

 grows in sandy or gravelly situations.
