Dendrobium chrysopterum
Hi Bernard,
I think that this is Dendrobium chrysopterum, which was described in 2001. Many plants in cultivation have been mistakenly labelled as Den. obtusisepalum.
Den. wentianum has orange flowers that have a spoon-shaped lip, which has a strongly cupped margin and notch at the apex of the centre line.
Hope that helps.
Cheers.
Gary

Bulbophyllum chrysopterum
Thanks Gary for your help giving me the correct name.
Have changed the name.
I received the following information from a reliable source.
1. D. wentianum has pendulous, branching stems; D. chrysopterum has spreading, unbranched stems.
2. D. wentianum has ovate leaves that are twisted at the base, causing them to point backwards towards the base of the stem; D. chrysopterum has narrowly ovate leaves spreading at right angles to the stem.
3. D. wentianum has lateral sepals that are connate in the basal part, producing a bell-shaped flower; D. chrysopterum has has nearly free lateral sepals, producing a wide-open, almost flat flower.
4. D. wentianum has uniformly orange or orange-red flowers; D. chrysopterum is orange-and-yellow.
5. D. wentianum is a high-altitude species and very difficult in cultivation; D. chrysopterum is from moderate altitudes (c. 800 m) and easily grown.
