This one can get quite large--the latest growth is now more than 60 cm (or 2 feet) long, and very pendulous as the result. The flowers are about 4-5 cm across, surprisingly large, and each inflorescence bears about 5-6 flowers.
One thing I noticed is that the lips are quite mobile, reminiscent of Bulbophyllums; the lips wiggle up and down when shaken by winds, suggesting the possible role in pollination. The blooms are scentless, unfortunately.
