Twenty-three species of Blume with capitate inflorescences are enumerated in Thailand. Kladwong & Chantar., a new species from North-eastern Thailand, is described and illustrated. J.R.I.Wood, Kurz and S.Moore are new records in Thailand. Craib is reinstated, and S.evrardiivar.parviflora J.B.Imlay, J.B.Imlay, Craib and Bremek. are treated as new synonyms. 19 taxa are lectotypified. A key to species, taxonomic notes and photographs are provided as well as a preliminary conservation assessment and distribution maps.

Previously, it was found that four types of glandular trichomes (GTs) are developed on the surface of all aerial organs in Doronicum species. A detailed study of leaves had shown that only two types of GTs form in them. Nothing was known about any differences of GTs on vegetative and reproductive organs.

Studies with secretory cavity contents and air-dried inflorescence extracts of the CBD-rich hemp strain, Cannabis sativa cv. 'Cherry Wine', were conducted to compare the decarboxylation rates of acidic cannabinoids between two groups. The secretory cavity contents acquired from the capitate-stalked glandular trichomes by glass microcapillaries, and inflorescence samples air-dried for 15 days of storage in darkness at room temperature were analysed by high-pressure liquid chromatography.

Cannabaceae species garner attention in plant research due to their diverse secretory structures and pharmacological potential associated with the production of secondary metabolites. This study aims to update our understanding of the secretory system in Hops ( L.), an economically important species especially known for its usage in beer production.
