Notes: Both stems and the oblanceolate leaves are fleshy, generally prostrate or ascending.  The inflorescence forms a loose coil, with double rows of symmetrically placed flowers.  Individual flowers are white, with a narrowly bell-shaped tube, and a yellowish-to-purple throat with 5 distinct veins.  This plant is now in the family Heliotropiaceae (formerly in Boraginaceae).  Photos #2 and 4 by CJH.
