Hoya merrillii (Small Leaf) is a great plant, with oval green leaves prominently veined in cream and light green shades, which put on a display of ruby red when exposed to plenty of bright, indirect light.  The flowers of this species are small, sweet-smelling umbels of orangey-yellow.  A vigorous grower, given basic Hoya conditions and occasional feeding during its growing season.  Native to the Phillippines.
