Systematics Section/ASPT Hsieh, Yun-Chen [1], Chang, Shih-Pai [1], Su, Huei-Jiun [1], Hu, Jer-Ming [1]. Host specificity of Balanophora laxiflora and allied taxa (Balanophoraceae). The holoparasitic Balanophora laxiflora is found in Taiwan and southern China. Two of the allied taxa, Balanophora japonica and Balanophora yakushimensis, are agamospermic, and only found in Japan and Taiwan. The later two taxa are closely related to B. laxiflora based on rDNA and ITS sequence phylogeny, and all three taxa are monophyletic groups. The intraspecific variation of these sequences is very low for B. japonica and B. yakushimensis, from the populations of Taiwan and Japan, where there are notable divergences among the individuals of B. laxiflora. We identified the hosts of the three Balanophora species by PCR and sequencing of the associated roots. The results showed that B. laxiflora showed a wide range of hosts, including Elatostema, Acer, Morus, Ficus, Alnus, Rubus, and Ardisia species. In contrast, B. japonica showed a host preference for Symplocos species. Interestingly, B. yakushimensis showed a host switch pattern that it prefers Distylium racemosum in Japan and Schima superba in Taiwan.
