c5.s26.t1.7

Under the name of *rásná*, the roots of *Vanda Roxburghii* and *Acampe papillosa*, are both indiscriminately used by native physicians. They are very similar in the appearance of their roots and leaves, though they differ much in their flowers and fruits. One native physician whom I consulted, pronounced both these plants to be *rásná*; when however I showed him the different flowers and fruits of the two species, he was puzzled. He had never looked to the flowers before, but only knew the roots and leaves. These epiphytes are very common on mango trees.
