Selinum cryptotaenium de Boiss.


Description from Flora of China

Pleurospermum glaucescens H. Wolff.

Plants 0.4–2 m, stout. Taproot 2–3 cm thick, branched. Stem erect, striate, branched above. Basal petioles 10–20 cm; sheaths somewhat inflated, 2–7 cm broad, purplish; blade triangular-ovate, 8–10 × ca. 8 cm, ternate-2–3-pinnate, glabrous or scabrid; pinnae 4–8 pairs; ultimate segments oblong-ovate or lanceolate, 10–20 × 5–8 mm. Umbels 8–10 cm across (to 20 cm across in fruit); bracts 12–15, linear, densely hispid, recurved, caducous; rays 12–28(–50), subequal, 5–7 cm, elongating in fruit, hispid; bracteoles 5–10, linear, entire or apex 2–4-lobed, ca. equaling pedicels, recurved. Calyx teeth linear-lanceolate, ca. 1 mm. Petals white or faintly pinkish, pinkish in bud. Styles short when young, ca. 2 × stylopodium in fruit. Fruit ovoid, ca. 4 × 3.5–4 mm; dorsal ribs subequal, narrowly winged, lateral ribs broad-winged; vittae 1 in dorsal furrows, 2–3 in lateral furrows, 4–6 on commissure. Fl. Jul–Aug, fr. Sep–Oct.

The type of Pleurospermum glaucescens (Yunnan: Lijiang, J. F. Rock 4481, E) and Wolff’s original description show no membranous margin on the bracteoles, well-developed, linear calyx teeth, and dorsally compressed fruit. These features are uncharacteristic of Pleurospermum, and so this species is treated here as a synonym of Selinum cryptotaenium.

Montane forests; 2500–4100 m. SW Sichuan, C and NW Yunnan.
