Schoenoplectus hotarui, an
annual herb occurring in wetlands, has cylindrical stems that grow
in clusters. Leaves are nothing but leaf sheaths due to the blade's
degeneration. Spikelets 2-7 attach stem tips; however, they look
like they are on points halfway to stem ends because bracts follow
the stem tips. The spikelets are 0.6-1.4cm long, 4-6mm wide, and
oval-shaped, with three stigmas. Fruit is 3-ridged flat, obovate-shaped,
glossy, and black-brown. Bloom time: July-October. |
