Genus Diglyphosa Blume, related to Chrysoglossum, is very rare in New Guinea. It differs from that genus, among other details, in that the column-foot lacks a spur. The dull orange flowers are not unattractive but have, according to most observers, an unpleasant smell, "like chicken shit," as one collector put it.
Genus Diglyphosa Blume contains 2 species, in New Guinea:
Diglyphosa latifolia
