Chapman's Goldenrod
Solidago chapmanii A. Gray is native to sandy soils at the margins of open pine and oak woods mostly in Peninsula Florida. The stems are short-hairy entirely or in lines or strips running down from upper stem leaf bases (Semple & Cook 2006 FNA). The species is now placed along with S. odora in S. subg. Triactis sect. Odorae. The species is diploid (2n=18).
The species was treated as S. odora ssp. chapmanii (A. Gray) Semple in FNA (Semple & Cook 2006 FNA). Plants can be similar to S. fistulosa or broader leaved S. odora. In a multivariate study of S. subsect. Venosae as then delimited (Semple, Bzovsky, & Tong 2016), S. chapmanii separated well from S. odora and more so from S. fistulosa now placed in S. sect. Venosae of S. subg. Pleiactila (Semple and Beck 2021). In the polygenomic study of Solidago (Semple et al. 2023), the one specimen of S. chapmanii formed the sister branch to the 3 S. odora specimens in a very strongly supported clade.
