We isolated and characterized 11 microsatellite loci for the Chinese yew, Taxus chinensis var. mairei, an endangered tree species in China, by constructing a (CA) 12 -enriched library. The number of alleles per locus ranged from 5 to 10. The observed heterozygosities ranged from 0.2500 to 0.8333 and the expected heterozygosities ranged from 0.5196 to 0.8680. No significant linkage disequilibrium was detected at these loci. However, four loci significantly deviated from Hardy-Weinberg
