沟稃草属及其近缘属植物颖片微形态特征研究

通过扫描电镜对沟稃草属及其近缘属共14属20种2变种植物颖片微形态进行观察。结果显示:(1)沟稃草属颖片脉间长细胞长筒形或短筒形,细胞壁波状弯曲,显著增厚;脉间短细胞单生,脉间栓细胞近圆形,脉间硅细胞缺失;脉上硅细胞单生,近圆形,有气孔器,气孔副卫细胞平行形至低圆屋顶形;脉上、脉间刺毛常见,有钩毛,无微毛,有乳突,无大毛。(2)根据颖片微形态特征所构建的系统发育树显示,沟稃草属与早熟禾族植物聚为一支,表明其亲缘关系较近,支持将沟稃草属置于早熟禾族中。(3)沟稃草属与拂子茅属、野青茅属植物相距较远,颖片微形态证据不支持将沟稃草属作为广义拂子茅属的成员,其应该单独成属。

Three new species in the genus Polygonum (Polygonaceae) from China

Three new species in Polygonum section Polygonum (Polygonaceae) from Xinjiang, China, are described and illustrated. Polygonum urumqiense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. aviculare L. in habit, but differs by having flowers densely clustered and spicate in the upper part of branches, stamens 5–6, and two types of achenes (the longer one densely and irregularly granulate on surface). Polygonum tachengense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. aviculare in the flowers not forming a raceme in the upper part of branches, the stamens 8, and the achenes striate-granulate on surface, but differs by the leaf blades linear-lanceolate, the midvein and lateral veins conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, the flowers 3–6 clustered together in the upper axils of branches. This species is also similar to P. patulum M. Bieb. in the erect stem, and the flowers 3–6 clustered together in the axils of the upper part of branches, but differs by the midvein and lateral veins of leaves conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, the leaves in the upper part of branches not becoming smaller gradually, and the flowers clustered in the upper axils of branches not forming a raceme, and the achenes striate-granulate on surface. Polygonum shiheziense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. argyrocoleon Steud. ex Kunze in the erect stem, the 3–6 flowers clustered in the upper axils of branches, the stamens 8, and the slightly smooth achenes, but differs by the midvein and lateral veins of leaves conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, and the flowers clustered in the upper axils of branches not forming a raceme. This species is also similar to P. tachengense in habit, but differs in the leaves borne in the upper part of branches becoming smaller gradually and the smooth, slightly shiny achenes. The pollen morphology, leaf epidermal characters and achene micromorphology of the three new species and their relatives were comparatively observed under the scanning electron microscope (SEM).
