Solanum

Berries < 15 mm in diameter, somewhat shiny, matte or slightly glaucous, globose; fruiting pedicels weakly spreading or more usually deflexed; anthers ellipsoid, not drying brownish orange; [native, adventive, or naturalized].

Solanum

Peduncle in fruit at right angles or more usually strongly deflexed downwards; berries 4-9 mm in diameter; calyx lobes appressed to surface of berry in fruit; styles exserted to 1.5 mm from the anther cone at anthesis; [adventive in our area]

Palafoxia

Disc corollas 7-10 mm long; pappus scales 1-8 mm long; leaves 2-20 mm wide, 3-15× as long as wide; [w. LA and TX, rarely adventive eastwards in FL and MS].

Heteranthera

Inflorescences 5-16-flowered, the axis elongating well beyond the spathe tip, thus many of the flowers borne well beyond the spathe; perianth lobes lavender to purple; [s. IL, s. IA, se. NE south to MS, LA, and s. TX; rarely adventive eastwards, as in n. AL and c. NC]

Helianthus

Leaves mostly alternate; petioles 5-9 cm long; ray flowers 10-30; [widely distributed in our region, native and adventive]

Plantago

Mature seeds 2.5-3 mm long, dark red, nearly flat on both sides; sepals 2.7-3.6 mm long, with an excurrent midrib; leaves typically toothed; [rare adventive in western part of our area]

Thymophylla

Pappus of 3-5 aristate scales; [heavy soils or loams, often on limestone or in disturbed areas in c. TX to the Rio Grande, adventive further east]

Digitaria

Spikelets 2.0-3.6 mm long; primary inflorescence branches 5-12, the inflorescence dense and mostly greenish; pedicels on upper paired spikelets shorter (1.0-2.5 mm long); leaf sheaths weakly papillose-hispid; [endemic to coastal prairies of TX, adventive in coastal VA and SC]
