Lespedeza Michx. (plate 1:1-6; 2:1-6; 3:1-6; 4:1-2) Pollen grains prolate, rarely subprolate or spheroidal, elliptic or rarely suborbicular in equa- torial view, 3-lobed-rounded in polar view, tricolporate, colpus margins smooth or jagged. Polar axis 20.7-33.1μm long, equatorial axis 15.4-20.9 μm long. Exine reticulate or foveolate, lu- mina verrucose or smooth under SEM. 2. Campylotropis Bge. (plate 4:3-4) One species in NE China, C. macrocarpa (Bge.) Rehd. Pollen grains prolate, elliptic in equatorial view, 3-lobed-rounded in polar view, 3-colporate, colpus linear, 25.1μm long, 1.79μm broad, colpus margins jagged, with a series of verrucae equal in size along one side visible under SEM. Polar axis 19.7μm long, equatorial axis 14.6μm long. Exine reticulate, lumina nearly rounded, verrucose at periphery under SEM. 3. Kummerowia Schindl. (plate 4:5-6) Pollen grains spheroidal, oblate or prolate, elliptic in equatorial view, obtuse-triangular in polar view, tricolporate, colups linear, 25.1μm long, 2.01μm broad, colpus margins sinuate. Polar axis 24.7-27.9μm long, equatorial axis 19.7-26.6μm long. Exine reticulate or subreti- culate, lumina nearly rounded, with verrocae visible under SEM. According to the pollen morphology of Lespedeza and its allied genera, the division of Lespedeza (s. lat.) into Lespedeza (S. str.), Campylotropis and Kummarowia by Schindler (1912) is reasonable. The subdivision of Lespedeza (s. str.) into Sect. Macrolespedeza and Sect. Lespe- deza by many botanists, and the treatment of Lespedeze juncea (L. f.) Pers. var. inschanica Maxim. as an independent species (i.e. Lespedeza inschanics (Maxim). Schindl.) are also suppor- ted by the pollen morphology shown in the present work. %K Lespedeza %K Campylotropis %K Kummerowia %K Pollen Morphology %K Taxonomy
