Perennial herbs , erect, almost glabrous, stems single, branching in upper part, cauline leaves with narrow long sheaths, leaf blades heterophyllous: bipinnate in lower part with primary segments on short petiolules and long narrow-linear lobes 3–5 (10) cm long, 1–2 (3) mm wide; and narrow-linear pinnate with entire narrow-linear segments 5–20 mm long in upper part. Bracts (1–) 3–5 extremely polymorphic, linear or pinnate with linear lobules 1–3 (–5) cm. The longest bracts exceed the umbel . Rays 14–15, thin, slightly unequal, scabrous, 3–15 cm long. Bracteoles 8, filiform, elongated, ciliated, 1–2 cm long, exceed umbellule. Pedicels about 5 mm . Flowers 20–40, calyx teeth noticeable, sharply unequal; petals pink, at base with well-developed claw, almost entire, with oval plate and short incurved apex. Stylopodia pressed-conical, styles short. Fruits glabrous, almost cylindrical, carpophore is bipartite almost to base. Mericarps slightly dorsally compressed, oblong; ribs all similar, narrowly winged, slightly widened at the base; vascular bundles slightly elongated in radial direction; commissure narrow. Secretory ducts between ribs 2–3, at commissural side 4–6; endosperm at commissural side almost flat. Type: Oreocomoides stelliphora (Cauwet & Farille) Kljuykov FIGURE 10. Lectotype of Oreocomoides stelliphora (E00296330). Affinities:— The new genus Oreocomoides markedly differs from Oreocomopsis in many morphological characters, such as heterophyllous leaf blades: bipinnate in lower part and narrow-linear pinnate in upper part; the primary leaf segments almost sessile on short petioles up to 0.5 cm long; bracts extremely polymorphic, linear or pinnate with linear lobules; calyx teeth developed; petals with oval plate, at base with well-developed claw; pedicels rounded; mericarps ribs all the same, narrowly-winged, slightly widened at the base. Etymology:— The name displays a connection with the genera Oreocome and Oreocomopsis . Distribution:— A monotypic genus distributed in Nepal , NW India . ( Fig. 2 ).
