These are my favourite novelty Sarcochilus orchids. Plect. (tridentata x erecta) x Perri. hillii. The flowers are only 7mm. x 5mm. and you can not see the colors in them until you see the photos. These two are from the same flask, one has red flowers and the other yellow.
Here are the parents in the making of Peri. Mem. Iris Pendle. You will notice the difference in the labellum of Olive Grace to Iris Pendle and the wider segments of the Iris Pendle. The flask number of Olive Grace is K50 and the flask number of Iris Pendle is Q70.
