We report 11 novel microsatellite primer pairs for the wild tea, Camellia sinensis (L.) O. Kuntze forma formosensis Kitamura. These simple sequence repeat markers were tested in 24 samples collected from wild tea populations, and in cultivars and C. japonica. The number of alleles ranged from 4 to18. The expected (HE) and observed (HO) heterozygosity were 0.687–0.946 and 0.042–0.792, respectively. All loci were significantly deviated from Hardy-Weinberg expectations due to the heterozygote deficiency, indicating a dramatic loss of genetic polymorphisms in the rare species. Significant LD was discovered in most loci. These primers may provide a tool for understanding demography and population structure in wild tea.
