Description

Freeman raised this taxon to species rank in 1975. For reference, here is his original description of Trillium angustipetalum (emphasis added):^[1]^: 55

Scapes erect, (19–) 25–48 (–67) cm long, (1.6–) 2.4–2.6 (–4.6) times as long as bracts. Bracts subsessile, ovate to broadly ovate, (9–) 10–20 (–24.5) cm long, basally divergent, the blades spreading, sparingly mottled with small brownish or dark green spots or unmottled, sometimes glossy beneath, the bases abruptly contracted into short thick petiole 10–25 mm long, the apices obtuse, rounded, or blunt. Sepals narrowly oblong-lanceolate to linear-lanceolate, (30–) 35–55 (–65) mm long, basally divergent, outcurved and spreading near middle, the apices acute or rounded-acute. Petals linear, (50–) 60–95 (–110) mm long, (6.2–) 8.0–9.8 (–11.0) times as long as wide, erect, dark purple, the apices acute, rounded-acute, obtuse, or blunt. Stamens erect, (11–) 14–20 (–23) mm long; filaments short, (2–) 3–4 (–5) mm long, slightly dilated basally, purple; anther sacs introrse, (9–) 12–17 (–18) mm long, on linear purple connectives (pollen yellow); connectives slightly prolonged about 1 mm (range 0–1.5 mm) into rounded projections. Carpels 4/5 as tall to equaling stamens; ovary ellipsoid-ovoid, (5–) 8–13 (–14) mm long, dark purple, usually sharply 6-angled near apex, sometimes with distinct wings; stigmas thickly subulate, (2–) 4–5 (–7) mm long, erect, dark purple. Flowers with spicy-musty odor. Berry ellipsoid to subgiobose, with sharp angles or wings extending and converging from sides to the persistent, fleshy stigmas.
