William Hemsley (botanist)
William Botting Hemsley (29 December 1843, in East Hoathly – 7 October 1924, in Kent) was an English botanist and 1909 Victoria Medal of Honour recipient. He was born in East Hoathly, Sussex and in 1860 started work at the Royal Botanic Gardens, Kew as an Improver, then Assistant for India in the Herbarium, finally Keeper of Herbarium and Library. He wrote a number of botanical works. In 1888, a genus of flowering plants from south-east Asia, belonging to the family Cucurbitaceae was named '' Hemsleya'' in his honour. He was elected a Fellow of the Royal Society Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural knowledge, including mathemat ... in June 1889.

Swertia
''Swertia'' is a genus in the gentian family containing plants sometimes referred to as the felworts. Some species bear very showy purple and blue flowers. Many members of this genus have medicinal and cultural purposes. Plants of genus ''Frasera'' are sometimes considered part of this genus, sometimes as a separate genus, and sometimes as synonymous. Selected species Species in the genus ''Swertia'' include, but are not limited to: * '' Swertia angustifolia'' Buch.-Ham. ''ex'' D. Don * ''Swertia bimaculata'' (Siebold & Zucc.) C. B. Clarke ** ''Swertia bimaculata'' (Siebold & Zucc.) Hook. f. & Thoms. * '' Swertia calcicola'' Kerr. * '' Swertia chinensis'' (Griseb.) Franch. ** '' Swertia diluta'' (Turcz.)

Xanthonoid
A xanthonoid is a chemical natural phenolic compound formed from the xanthone backbone. Many members of the Clusiaceae contain xanthonoids. Xanthonoid biosynthesis in cell cultures of ''Hypericum androsaemum'' involves the presence of a benzophenone synthase condensing a molecule of benzoyl-CoA with three malonyl-CoA yielding to 2,4,6-trihydroxybenzophenone. This intermediate is subsequently converted by a benzophenone 3′-hydroxylase, a cytochrome P450 monooxygenase, leading to the formation of 2,3′,4,6-tetrahydroxybenzophenone. Some examples are tomentonone, zeyloxanthonone and calozeyloxanthone isolated from the bark of ''Calophyllum tomentosum'', apetalinone A, B, C and D from '' Calophyllum apetalum'', gaudichaudione A, B, C, D, E, F, G, H, gaudichaudiic acid A, B, C, D, E, morellic acid and forbesione from '' Garcinia gaudichaudii'', methylswertianin and bellidifolin from '' Swertia punicea'' or psorospermin obtained from '' Psorospermum febrifu ...
