- Geodorum (Orchidaceae) has approximately ten species, and is mainly distributed in tropical Asia. Among them, Geodorum eulophioides Schltr. is of major conservation concern as it has only four known populations, two each found in China and others in Burma. In this study, we developed 18 polymorphic microsatellites markers in G. eulophioides with the number of alleles ranging from two to 17. The expected and observed heterozygosities ranged from 0.046 to 0.918 and from 0.048 to 1.0000, respectively. The cross-species amplification rates for the sympatric G. recurvum (Roxb.) Alston and G. densiflorum (Lam.) Schltr. were 100 and 83.33 %, respectively. These markers developed would be useful for conservation and population genetic studies.
