英文摘要

Pollen grains and seed surface features of the four species in the genus Dactylicapnos Wall. (Papaveraceae) from China were studied under light microscope (LM) and scanning electron microscope (SEM). Pollen grains are usually subspheroidal in shape, and 6-pantocolpate, with the diameter being 29.2 - 50.8 mum. Although pollen grains of the four species studied have many common features, they show some interspecific differences. Depending on the difference of the species, the colpi are distinct ( D. roylei (Hook. f. et Thoms.) Hutch.), or indistinct ( D. scandens (D. Don) Hutch. and D. lichiangensis (Fedde) Hand.-Mazz.) to obscure ( D. torulosa (Hook. f. et Thorns.) Hutch.); the membrane is verrucate ( D. scandens) to tuberculate ( D. roylei, D. lichiangensis and D. toralosa), with some tubercles being united to block in pollen grains of D. roylei; the exine surface is indistinctly rugulate ( D. scandens and D. lichiangensis) to densely tuberculate ( D. torulosa). Seeds in the four species are usually black in color, and dull or lustrous, and show quite different surface features among the species. The seed surface is verrucate in D. scandens, twisted-striate in D. torulosa, densely spinulose in D. lichiangensis, and finely reticulate in D. roylei. These results are very helpful in distinguishing between the species in the genus, and support its independence as a separate genus from Dicentra Borckh.
