Oberonia

Lindl.
Tufted epiphytes . Leaves distichous , equitant , ensiform (very rarely terete). Flowers very minute in dense subeylindric spikes or racemes. Sepals broadly ovate or oblong , subequal . Petals smaller . Lip sessile , concave , entire or 2-4 lobed . Column very short ; anther terminal , incumbent ; pollinia 4, waxy, cohering by a viscus –Species about 60, Tropical Asiatic , Australian and Pacific .

The flowers are generally 2 to each bract ,which is lanceolate and free or broader and more or less convolute , sometimes very broad and forming a tube round both flowers; the upper flower has often a sheathing obtuse bracteole.- The genus wants a careful study of living specimens. I am far from satisfied with the following delimitation of species , the specimens being in some cases quite insufficient for a sure diagnosis .
