Described by Nuttall (1818) from collections made at Fort Mandan.
The type is at PH.
5. * [Dracocephalum] parviflorum. Flowers, verticillate, subcapitate;
leaves ovate-lanceolate, deeply serrate, and petiolate,
bractes foliaceous, ovate, ciliate, and serrate, serratures
conspicuously mucronate; upper segment of the
calix much larger than the rest; flower scarcely longer
than the calix. Hab. Around Fort Mandan, on the Missouri;
on the borders of thickets. Obs. Biennial; nearly
smooth, stem, and petioe a little pubescent; flowers almost
imbricated in a leafy capitulum, very small, and
nearly white; calix awned, arid and membranaceous, semiquinquefid;
bractes divaricately awned; upper lip of
the corolla emarginate, arched; lower 3-lobed central
lobe subcrenate. Flowering time, July. Apparently allied
to D. Moldavica, but the leaves are entirely destitute
of punctures: scarcely a congener with D. virginianum,
and closely allied to Melissa.

DeLong Park was a private residence that was left fallow for a number of years, then converted to a city park in 2021-2022. This 2023 collection was made, therefore, in the second growing season after park construction.
Not previously collected in Golden; unclear whether this plant was previously here, brought in with the soil amendment, or was a contaminant in the seed mix.

Since the adjoining neighbors have stopped mowing this area, the Bromus inermis “smooth brome” has gotten larger.
There are also several native subshrubs that are competing with the smooth brome, including:
Ambrosia psilostachya,
Artemisia dracunculus,
Artemisia ludoviciana,
Heterotheca villosa,
Liatris punctata,
Symphyotrichum ericoides,
Pediomelum tenuiflorum,
