An emended description of the poorly known Begonia serotina A.DC. (Begoniaceae) is provided and B. asympeltata L.B.Sm. & Wassh. is newly synonymised with that species. The classification of Begonia serotina in B. sect. Knesebeckia (Klotzsch) A.DC. is confirmed. Begonia compacticaulis Irmsch. is shown to be a synonym of B. ludwigii Irmsch., while the circumscription of B. compacticaulis in the Flora of Ecuador is shown to be based on specimens of both B. ludwigii and B. serotina. Begonia serotina is more widely distributed than previously recorded and is newly reported from Ecuador’s Los Rios, Bolivar and Loja provinces and Peru’s Tumbes region. Begonia serotina is reassessed as Vulnerable (VU), according to IUCN criteria.

Facchinia Rchb. (Alsinoideae–Caryophyllaceae), earlier found not to be part of Minuartia s.str., is here revised. The genus contains seven species, one of which has two subspecies. Seven new combinations are made: Facchinia cerastiifolia (Ramond ex DC.) Dillenb. & Kadereit, F. cherlerioides (Sieber) Dillenb. & Kadereit, F. cherlerioides subsp. aretioides (Port. ex J.Gay) Dillenb. & Kadereit, F. grignensis (Rchb.) Dillenb. & Kadereit, F. herniarioides (Rion) Dillenb. & Kadereit, F. rupestris (Scop.) Dillenb. & Kadereit, and F. valentina (Pau) Dillenb. & Kadereit. Keys to Minuartia s.str., the Old World segregate genera of Minuartia s.l., and to the species and subspecies of Facchinia are provided. All taxa are described and mapped, and some are illustrated.

The island of Folegandros, located between the Milos and Santorini archipelagos in the southern Kiklades (Greece), constitutes together with Ios and Sikinos the south-central part of the phytogeographical region of the Kiklades. Its flora consists of 474 taxa, 47 of which are under statutory protection, 40 are Greek endemics and 145 are reported here for the first time. We show that Folegandros has the highest percentage of Greek endemics in the phytogeographical area of the Kiklades. The known distribution of the endemic Muscari cycladicum subsp. cycladicum is expanded, being reported for the first time outside the South Aegean Volcanic Arc. The floristic cross-correlation between Folegandros and other parts of the phytogeographical region of the Kiklades by means of Sørensen’s index revealed that its phytogeographical affinities are stronger to Anafi Island than to any other part of the Kiklades.

William Griffith wrote an account of the plants collected by Theodore Cantor in 1840 while on a military expedition to Chusan in China. This was published posthumously in 1854, but was also distributed in 1844 or 1845 as a preprint. The 14 new names at species rank appearing in the paper are reviewed (including the often overlooked Leucopogon ophirensis and Corylopsis grata) and their typification considered. Lectotypes are designated for 10 of these names, one second-stage lectotypification is proposed, and Corylopsis griffithii Hemsl. is also lectotypified.

Stephania pierrei Diels (Menispermaceae) is a species recorded from the Indo-Chinese Peninsula. It is the only species of the genus bearing apetalous flowers. Diels did not cite a holotype in his publication in 1910. We provide here a more precise description of Stephania pierrei and select a lectotype for this name.

A new species of Kuepferia (Gentianaceae), K. pringlei D.Maity & Sentu K.Dey from north Sikkim, Eastern Himalaya, is described and illustrated. Details of habitat, phenology and conservation status are given, and it is compared to related species. This previously undescribed species is most similar to, but distinct from, Kuepferia leucantha (Harry Sm. ex T.N.Ho & S.W.Liu) Adr.Favre, known from Bhutan and China.
