fruit
Fruit schizocarp schizocarp:
fruit formed from a single ovary, with fused carpels, with or without accessory tissue; splitting between locules to form distinct, indehiscent, usually one seeded segments; usually dry, rarely fleshy (compare mericarp)
of 1–4 achenesachenes:
a dry, indehiscent, one-seeded fruit, with seed attached to pericarp at a single point
, usually falls united. Acheneachene:
a dry, indehiscent, one-seeded fruit, with seed attached to pericarp at a single point
6–8 mm long x 2–4.5 mm wide, cylindrical, recurved beakbeak:
a usually firm, terminal appendage, sometimes tapered
(persistent stylestyle:
in a flower, the narrow and elongated part of the pistil between the stigma and the ovary; sometimes persisting in fruit
), two recurved laterallateral:
(of embryo) embryo lies along the side of the seed, generally towards one end; of, at, or from the side; in grasses, can refer to the sides adjacent to the dorsal and ventral sides
wings, one seeded. Pericarppericarp:
fruit wall or fruit coat
brown, spongyspongy:
soft, light, discontinuous but cohesive, and somewhat resilient
.
Seed and embryo likely similar to Juncaginaceae.

AchenesAchenes: a dry, indehiscent, one-seeded fruit, with seed attached to pericarp at a single point with recurved beaks (persistent styles) and persistent tepalstepals: a member of the perianth, when it cannot be differentiated into a calyx and corolla and stamens. |
