Differences Between Hoya Pandurata and Hoya burmanica

Hoya burmanica was described by Rolfe in 1920; it is endemic to Miramar (formerly Burma – hence the name), and India. Hoya pandurata has much thicker and more rounded leaves than the thin triangular leaves of Hoya burmanica. The flowers are also different in that the corolla of H. burmanica is much more cupped shaped than the reflexed corolla on H. pandurata. There also must be different clones of Hoya burmanica in circulation as the corolla on my flowers are light pink as opposed to the bright yellow or green that I have seen online.
