Flat-Topped Goldenrod - Slender Goldentop - Mississippi Valley Goldentop - Bushy Goldentop - Mississippi Valley Flat Top Goldenrod
Euthamia caroliniana (Linnaeus) Greene ex Porter & Britton
Asteraceae (Composite Sunflower) Family

   

Plant is an upright, smooth or hairy peren-
nial with angular stems and rhizomes from which new growth emerges. Preferred habitat is glades, moist ditches, roadsides and rich prairies. Distribution is through-
out the Escambia region.

A similar species, E. minor, is alternate on the stem, linear in form, with a very prominent midvein and is resin-dotted on the underside.  Leaf margins are usually smooth and the tip tapers to a point. Leaf base has a minute stalk but it appears to emerge directly from the stem.

Flowers are at the top of the flowering stem in clusters of heads (usually more or less flat); symmetrical in shape.  Disc flowers are bisexual and yellow; ray flowers are female and yellow.

Fruit is achene (a seed which outer layer is fused to it).

The related E. tenuifolia is similar in every aspect except the linear leaf has a faint vein that extends parallel to the midvein on both sides. It should be noted that some botanists consider these species to be the same as goldenrod hybridizes easily and both plants reside in similar locations.
