~~Annual Lamiaceae~~ Dracocephalum parviflorum

Literature Cited:
- Nuttall, Thomas, 1818.

Described by Nuttall (1818) from collections mane 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.
Principally a Siberian genus.

‡ Heuchera Hallii (sp. nov.) : hirsutula; thyrso racemiformi suhlaxo 16-30-floro: bracteis pedicellos vix superantibus ; florihus albidis (nunc roseo tinctis?): calyce lato-campanulato 5-lobo, lobis, lato-ovatis; petalis spathulatis obtusis exsertis: staminibus stylisque inclusis. Scapes usually a span high. Flowers about three lines long, but the calyx twice the breadth of that of H. bracteata, and very different in shape. Pedicels, when fully developed, sometimes nearly as long as the flower. Leaves as in the preceding species [H. bracteata], considerably variable.

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, and, of course, the shrub Ericameria nauseosa var. graveolens.
