Abstract
Two new species of Oreocharis Benth. from Fan Si Pan, the highest mountain in Vietnam (Sa Pa) are described and illustrated. Oreocharis grandiflora W.H.Chen, Q.H.Nguyen & Y.M.Shui, is similar to O. flavida Merr. from Hainan province, China, but differs mainly by its larger and infundibuliform corolla, stamens adnate to the base of the corolla tube and stamens coherent in two pairs. The second, Oreocharis longituba W.H.Chen, Q.H.Nguyen & Y.M.Shui, is similar to O. hirsuta Barnett, endemic to northern Thailand, but mainly differs in its pubescence, coherent stamens and glabrous filaments.
| Oreocharis grandiflora |
- Habitat: This plant typically grows as a stemless, herbaceous perennial with leaves crowded at the base of a short rootstock.
- Appearance: It features elliptic or ovate, grayish-green leaves that are covered in tawny, multicellular hirsute hairs. It produces yellow, tubular or funnel-shaped flowers.
- Distinguishing Features: Unlike similar related species in the region, O. hirsuta has obtuse-to-rounded leaf bases, hirsute hairs, subequal corolla lips, and anthers that are free rather than coherent.
- Similar Relatives: It shares morphological similarities with other Southeast Asian and Chinese species like O. aurea and O. tsaii, and has related species in Vietnam (such as O. longituba).
