diagnosis
Diagnosis. Chrysosplenium ramosissimum is most similar to the sympatric species C. valdepilosum, but the former is readily distinguishable by the presence of yellowish-green (vs. bright yellow) bracteal leaves during flowering, highly branched and elongated sterile branches after fruiting (Fig. 4), shiny silvery dots on sterile branch leaves and larger tubercles on the seed coat (Fig. 3).
distribution
Distribution. Chrysosplenium ramosissimum is only known to exist on Mt. Seonjaryeong in Gangwon-do, Korea, at an elevation of 630 - 910 m. To date, only one population of approximately 2,000 individuals has been discovered, near a small creek. In the absence of additional data, we presently score it as Data Deficient (DD), according to the IUCN Red List criteria (IUCN 2001).
etymology
Etymology. The specific epithet of the new species refers to the highly branched sterile branches after fruiting.
