Ecology & Life History
Help
General Description: Pod Grass is a grass-like perennial herb with stems that are 2-4 dm high and arising singly from creeping rhizomes. Alternate, strap-like leaves that are 1-4 dm long, sheath the stem and become smaller upward. The lower stems are usually covered with old membranous sheathing bases. 3-12 stalked flowers are borne on the upper stem in the axils of reduced leaf sheaths. Each flower has 6 undifferentiated, greenish white, separate petals and sepals that are ca. 3 mm long, 6 stamens, and 3 ovaries that are united at the base. The (usually) 3 capsules are 5-8 mm long and have 2 seeds.
Technical Description: Stem simple, zigzag and partially sheathed by leaves with conspicuously dilated sheaths. The basal leaves with overlapping sheath. The cauline leaves 1-3, separate, erect, 5-30 cm long, 1-3 mm wide, with a round pore at the apex. Racemes few flowered, 3-10 cm long, lowest bract foliaceous with well developed blade, the second with small or reduced or no blade, the upper bladeless. Sepals and petals greenish ovate-lanceolate, 2-3 mm long. Anthers lanceolate, 2.5 mm long, twisted after anthesis. Carpels 3, globulose or ovoid, united at the base, 2 ovuled, bearing flat sessile stigmas. Follicles inflated, divergent, 1-2 seeded, 6-8 mm long, brown or straw colored.
Diagnostic Characteristics: The sheathing, grass-like leaves and relatively large, 3-parted fruits are diagnostic. Pores at leaf tips, reduced upper leaves, persistent remains of old leaves.
Duration: PERENNIAL, DECIDUOUS
Ecology Comments: Almost totally restricted to bogs.
