Common Name: BUR-REED Habit: Plants generally submerged except inflorescence, or vegetative when all-submerged (emergent to +- terrestrial); rhizomes, stolons slender. Stem: unbranched proximal to inflorescence. Leaf: blade flat to convex, 3-sided, or abaxially keeled. Inflorescence: heads axillary and terminal, 2--60+; bracts leaf-like, distal reduced. Staminate Flower: stamens 2--8. Pistillate Flower: ovary chambers 1--2(4), stigmas generally 1(2--4). Fruit: drupe-like, spongy; perianth parts attached, style and generally stigmas persistent as beak; floating, water-dispersed. Etymology: (Probably Greek: swaddling band, for strap-shaped leaves) Note: Fruit head diam including fruit beaks; fruit body lengths except beak, stalk-like base; beak lengths including stigmas.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
