Vegetative morphology. Plants 3–15(–20) cm high; perennial herbs; glandular viscid, or not glandular viscid. Only fibrous roots present. Ground level or underground stems horizontal, or vertical; rhizomatous, or stoloniferous; elongate; 0.5–3 mm wide. Caudex present. Aerial stems erect, or ascending. Aerial stem trichomes spreading, or erect (if applicable). Leaves mainly basal, or distributed along the stems; alternate, or opposite (Phlox); persistent, or dying annually and non-persistent. Petioles present, or absent; 0.5–2.5(–3.5) mm long (if applicable); winged (at the base, if applicable); hairy; woolly. Petiole hairs shorter than the diameter of the petiole; spreading, or erect; floccose (if applicable); smooth. Leaf blades simple, or compound. Leaf blade bases truncate (if applicable). Blades 6–55 mm long, 0.8–10(–18) mm wide, spreading, linear (Phlox), flat or involute, veins parallel or veins reticulate. Blade adaxial surface glabrous. Blade abaxial surface glabrous. Blade margins with glandular hairs (Polemonium); apices acuminate, or acute. Leaflet arrangement pinnate (Polemonium). Leaflets (4–)6–10(–12); 4–12 mm long; 1.5–4 mm wide; elliptic; veins inconspicuous.

Reproductive morphology. Flowering stems with leaves. Flowering stems hairy. Flowering stems woolly (if applicable). Flowering stem hairs white or translucent (if applicable); glandular hairs present (Polemonium), or absent (Phlox). Flowers solitary (Phlox), or in inflorescences (Polemonium). Inflorescences cymose (Polemonium); dense; globose or sub-globose; 2–4 cm long; 20–40 mm wide (if applicable). Pedicels present (but short Polemonium); with glandular hairs (Polemonium). Flowers per inflorescence 1 (Phlox), or 3–7(–9); medium-sized, or large; radially symmetrical (actinomorphic). Sepals conventional; 5; fused; 4–7 mm wide; green. Calyx tubular; 5-lobed; hairy. Calyx hairs woolly; glandular, or non-glandular; white or translucent. Petals conventional; fused; 5; yellow, or pink, or purple, or blue; with contrasting markings (centre of the flower near the throat is yellow); 14–18 mm long. Corolla tubular, or rotate; 5-lobed. Stamens (3–)5; stamen filaments glabrous; fused to the corolla. Anthers yellow; ellipsoid, or short-cylindrical; 1.4–3.2 mm long. Nectaries present. Ovary superior; carpels 3; syncarpous. Ovaries ovate, or sub-globose; glabrous. Styles 1; (7–)7.5–10 mm long; straight. Stigmas per ovary 3. Stigma lobes 1–1.6 mm long. Placentation axile. Ovules per ovary numerous. Fruit sessile, or stalked; with calyx persisting; dry; a capsule; ovoid; not distinctly flattened; dehiscent; splitting to the base into separate segments.
