Novelties in Fimbristylis (Cyperaceae) from Zhejiang, China: two new species and a new variety

In preparation for the second edition of Flora of Zhejiang, two new species and a new variety of Fimbristylis, F. long-quanensis, F. minuticulmis and F. stolonifera var. cylindrica, are described and illustrated in the present paper. Fimbristylis longquanensis is similar to F. complanata, but differs in being an annual habit with rhizomes absent, leaves 2-2.5 mm wide, bracts longer than or nearly equal to inflorescence, and nutlets smooth. Fimbristylis minuticulmis is simiar to F. diphylloides, but differs in having culms 2-12 cm tall, much shorter than leaves, spikelets broadly ovoid, obtuse at apex, scales acute at apex, stigmas 2, and nutlets biconvex. Fimbristylis stolonifera var. cylindrica differs from its autonymic variety in having the inflorescence simple, and spikelets cylindrical, 8-15 x 2.5-3 mm.
