The present study was conducted to investigate anti-nociceptive and anti-inflammatory effects of the leaves of Ilex latifolia Thunb (I. latifolia) in in vivo and in vitro. Writhing responses induced by acetic acid and formalin- and thermal stimuli (tail flick and hot plate tests)-induced pain responses for nociception were evaluated in mice. I. latifolia (50 - 200 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive non-steroidal anti-inflammatory drug (NSAID), inhibited the acetic acid-induced writhing response and the second phase response (peripheral inflammatory response) in the formalin test, but did not protect against thermal nociception and the first phase response (central response) in the formalin test. These results show that I. latifolia has a significant anti-nociceptive effect that appears to be peripheral, but not central. Additionally, I. latifolia (50 and $100{\mu}g/mL$) and 3,5-di-caffeoyl quinic acid methyl ester ($5{\mu}M$) isolated from I. latifolia as an active compound significantly inhibited LPS-induced NO production and mRNA expression of the pro-inflammatory mediators, iNOS and COX-2, and the pro-inflammatory cytokines, IL-6 and $IL-1{\beta}$, in RAW 264.7 macrophages. These results suggest that I. latifolia can produce antinociceptive effects peripherally, but not centrally, via anti-inflammatory activity and supports a possible use of I. latifolia to treat pain and inflammation.

Tar spots have been observed on Ilex cornuta in Korea since 2015. Based on morphological and molecular analyses, the fungus responsible was determined to be a Rhytisma species, with characteristics similar to R. ilicis-latifoliae observed on Ilex latifolia from Japan. Herein, we document the first report of Rhytisma sp. on I. cornuta.

Through the collection of herbarium specimens in Bhutan over the years, new plant species are discovered nearly annually. Thus, this paper reports two new genera and 19 new records of flowering plant species from Bhutan. The new genera include Eurycorymbus of the family Sapindaceae and Homalium of the family Salicaceae. The new records of plant species are Eranthemum erythrochilum (Acanthaceae), Hemidesmus indicus (Apocynaceae), Ilex umbellulata (Aquifoliaceae), Canarium strictum (Burseraceae), Ehretia acuminate (Boraginaceae), Vaccinium sikkimense (Ericaceae), Nothapodytes foetida (Icacinaceae), Machilus edulis (Lauraceae), Grewia asiatica (Malvaceae), Hibiscus fragrans (Malvaceae), Cipadessa baccifera (Meliaceae), Baccaurea javanica (Phyllanthaceae), Canthiumera glabra (Rubiaceae), Homalium napaulense (Salicaceae), Eurycorymbus cavaleriei (Sapindaceae), Acmella radicans (Asteraceae), Silene latifolia (Caryophyllaceae), Cleome rutidosperma (Cleomaceae), and Cuphea carthagenensis (Lythraceae). Morphological determinations of the genera and species were carried out at the National Herbarium (THIM) of the National Biodiversity Centre of Bhutan. Brief descriptions of the species, phenology, and photo plates are provided in this annotated checklist.
