    Asteraceae: Antennaria parvifolia

    No full text
    Antennaria parvifolia is a perennial herb in the Asteraceae family. It grows from a fibrous root system and spreads asexually by slender, above-ground stolons, often forming low, dense mats. Stems are simple, unbranched, and erect to ascending, typically 5–20 cm tall, and are densely covered with soft, woolly hairs (notable pubescence). Basal leaves are numerous, forming a rosette; they are oblanceolate to spatulate, usually 1–4 cm long and 2–7 mm wide, with entire margins, a green upper surface, and a grayish, woolly underside. Cauline leaves are few, much smaller, linear to narrowly lanceolate, and reduced up the stem. This species is dioecious, with male and female flower heads on separate plants. Flowering occurs from May to July. Inflorescences are clusters of 2–7 terminal flower heads, each about 5–8 mm across. Male heads have creamy white, tubular florets with conspicuous anthers; female heads have white, hairlike pistillate florets. The involucre bracts are white or tinged with pink, giving the flower clusters a soft, “pussytoe” appearance. The fruit is a tiny, one-seeded achene (about 1 mm long) with a tuft of white pappus bristles for wind dispersal, maturing in early to midsummer. Small-leaf pussytoes is native to South Dakota, found in dry prairies, grasslands, open pine woods, and rocky or sandy sites, and is widespread but more abundant in western and central parts of the state.https://openprairie.sdstate.edu/nativeplant/1262/thumbnail.jp

    Lamiaceae: Glechoma hederacea

    No full text
    Glechoma hederacea is a perennial, creeping herbaceous plant that spreads by stolons, forming dense mats on the ground. Stems are square in cross-section, typically reaching 10–50 cm in length, hairy, and spreading laterally or creeping along the soil surface, often rooting at nodes. Leaves are opposite, rounded to kidney-shaped with scalloped edges, 2–4 cm across, and aromatic when crushed. Flowering occurs from spring to early summer (April–June). The flowers are small, tubular, and bilaterally symmetrical, borne singly or in small clusters from leaf axils. They are typically light purple to bluish with darker purple markings on the lower lip. Each flower has five sepals and five petals. The sepals form a tubular calyx about 0.5–1 cm long, with five pointed lobes that are lanceolate in shape. The petals are fused into a two-lipped corolla about 1–1.5 cm long: the upper lip is hooded and two-lobed, while the lower lip spreads out and is three-lobed with a slightly notched center lobe. Flowers are bisexual with four stamens and a single, superior ovary formed from two fused carpels, which develops into a four-lobed schizocarp fruit that splits into four one-seeded nutlets that mature in late summer. Ground ivy is introduced and widespread in South Dakota, found in lawns, gardens, roadsides, and shaded disturbed areas.https://openprairie.sdstate.edu/nativeplant/1310/thumbnail.jp
