? Oreomyrrhis nanhuensis Chih H. Chen & J. C. Wang

Oreomyrrhis gracilis Masamune; O. involucrata var. pubescens Masamune; ?O. nanhuensis Chih H. Chen & J. C. Wang; O. taiwaniana Masamune.

Plants 6–20 cm high. Tap root short. Petioles 2–6 cm; leaf blade 1.5–3.5 × 1–2 cm; pinnae 2–3 pairs, the proximal short-petiolulate; ultimate segments linear, linear-lanceolate or oblanceolate, entire or 2–3-lobed, hirsute to glabrous. Peduncles 5–15 cm, hirsute; bracts 4–8, base slightly united, linear to oblanceolate, 1–2 × 2–10 mm, hirsute to glabrous; pedicels 10–20, much shorter than bracts, hirsute. Petals 1.2–1.5 × ca. 1 mm, glabrous to hirsute. Fruit purple-black, 3–4 × 2–5 mm, glabrous. Fr. Oct–Nov.

A recent revision of Oreomyrrhis in Taiwan (Chen & Wang, Bot. Bull. Acad. Sin. 42: 303–312. 2001) reinstated O. taiwaniana as a distinct species and described a new species, O. nanhuensis. The morphological differences appear slight and further work is needed to confirm this treatment.

Grassy slopes on mountain ridges; 2000–4000 m. C Taiwan.
