Title: Pollen morphology of Cuscuta (Convolvulaceae) in Taiwan.
Abstract:The pollen morphology of five taxa of Cuscuta, C. australis, C. campestris, C. chinensis, C. japonica var. formosana and C. japonica var. japonica (Convolvulaceae) in Taiwan was investigated by using ...The pollen morphology of five taxa of Cuscuta, C. australis, C. campestris, C. chinensis, C. japonica var. formosana and C. japonica var. japonica (Convolvulaceae) in Taiwan was investigated by using LM, SEM and TEM. The pollen of Cuscuta is three to six colpate, zonocolpate or pantocolpate colpus with granules, tectum with scabrate processes, ektexine reticulate or finely reticulate, and endexine thinner than ektexine. Two distinct pollen types of Cuscuta spp. in Taiwan are recognized. Type 1 is small, and has colpus with granules, and ektexine finely reticulate, including C. australis, C. campestris and C. chinensis. Type 2 is medium in size, and has colpus with granules, scabrate processes on surface of granule and ektexine reticulate, including C. japonica var. formosana and C. japonica var. japonica. Pollen types correspond with Yuncker's subdivision of the genus Cuscuta, type 1 for subgenus Grammica and type 2 for subgenus Monogyna. Meanwhile, pollen characteristics are also helpful in identifying species.Read More
