Elimination: O.anomalum, O.cupulatum, O.rupestre were all eliminated because they grow on rock and mine was on a branch. O.pulchellum has the leaves twisted when dry and O.tenellum has the leave flexuose when dry so these were eliminated too. O.diaphanum has a white hair point so not that one. Others were ruled out on leaf shape and Lyellii due to lack of gemmae. We are now left with a choice of three: O.stramineum, O.affine and O.striatum.
