An orchid sp enthusiast was telling me that this is actually not Dend secundum since the flower was all round......There is a specific name for this Dend sp which is from PNG...So any of you guys out here who can recall the true ID for this sp..?
I'm not sure about it,but whatever it is if everybody agree that the ID is Dend.secundum.....let say we just stick to it until someone can reveal its true ID.
Pak, I wouldn't be surprised if there was another form of this species, after all it has a very wide distribution range; Myanma, Thailand, Sumatra, Laos, Java, Cambodia, Vietnam, Borneo, Philippines and some of the Pacific Islands.
Your image of this species seems to conform to the normal form.
The name you were looking for is Dendrobium bursigerum Lindl.
Unfortunately, this name is currently not accepted by the World Checklist but lumped in with Den. secundum, which has all its flowers borne on one side of the rachis (= secund). Hopefully that will change when it manages to catch up.
Howard Wood says:
Distinguished by flowers oriented radially (like a bottlebrush) and usually fall bloom. In Den. bursigerum the final resupination seen in Den. secundum, which lines up the flowers, does not occur. Other less crucial differences are that Den. busigerum may have as many as 4 simultaneous inflorescences per pseudobulb, and its raceme is longer and arching, like a foxtail.
Range: Philippines, low altitudes to 500 m, also Borneo.
Another distinguishing feature, between Dendrobium bursigerum and Dendrobiun secundum, is that the flowers of Dendrobium bursigerum are considerably smaller than those of Dendrobium secundum.
I have been a regular visitor to the Philippines since 1977, and between 1997 and 2000 I lived there permanently, whilst writing a book on Philippine orchid species. During this time I have never seen a plant, which was from the wild, that could be considered to be Dendrobium secundum. Nor have I ever seen what could be considered as an intermediate.

Love the attachment with the unusual aspect of this species.
