About Solidago gattingeri Chapm. ex A.Gray
Solidago gattingeri, commonly called Gattinger's goldenrod, is a goldenrod species. It is native exclusively to the Ozark Mountains of Arkansas and Missouri, and the Nashville Basin of Tennessee. Its preferred habitats are cedar glades, cedar barrens, and limestone outcrops, and it is adapted to grow in dry environments. This is a perennial plant that produces yellow flowers in late summer. A single individual can produce up to 250 small yellow flower heads: some arranged in large arrays at the top of the plant, and others growing in smaller clusters on side branches. It can be told apart from the closely related Solidago juncea by having fewer flowers per head, with only 1 to 5 ray florets and 4 to 11 disc florets. It is also closely related to Solidago missouriensis, but differs from that species by having bract-like upper leaves and shorter rhizomes.
