| Schoenoplectus hotarui,
an annual herb occurring in wetlands, the stems of which are
cylindrical, 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. |
