Eleven names in Polygonatum are lectotypified, two additional names have additional isotypes reported, and discussions of taxonomy are provided for eight species as part of an ongoing revision of the genus.

Colchicum akanii Sonay, M. Keskin & Balos (Colchicaceae) from Elazığ, eastern Turkey, is described as a new species. It is morphologically similar to C. balansae and C. macrophyllum, but differs from them mainly by the structure of the corm and outer and inner tunics, cataphyll colour, leaf shape and size, tessellate perigon, filament that is much shorter than tepals, as well as capsule and seed structure. Following the IUCN criteria, we assessed C. akanii to be Critically Endangered (CR).

Onosma zaferkayae Binzet (Boraginaceae, Lithospermeae) is described and illustrated as a new species from eastern Anatolia, Turkey. It morphologically resembles O. thracica and O. demirizii, but has taller stems, larger basal and cauline leaves, longer pedicels, larger bracts, shorter and golden yellow corollas, and larger nutlets. Based on IUCN criteria, the conservation status of O. zaferkayae is assessed to be Critically Endangered (CR B1(i)B2ab(ii,iii)).

The typification of the Linnaean name Allium fistulosum (Amaryllidaceae) is revised by superseding the previous proposal (neotype). Due to the existing original material (Dodoens' illustration), the neotypification is not correct according to Art. 9.13 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code). In addition, an herbarium specimen kept at S-LINN is designated as epitype to ensure the correct application of the name.

Dolichandrone falcata Seem. (Bignoniaceae) is shown to be the correct name for the tree species native to India. A lectotype is designated here.

Litsea nigrescens Gamble is recognized and treated as a variety of L. oleoides (Meisn.) Hook.f. It differs from L. oleoides only by having predominantly alternate leaves which in the latter are opposite.

Cremanthodium dibangii Vik. Kumar & Rahul Kumar (Asteraceae, Senecioneae) is described and illustrated as a new species from Dibang Valley District in Arunachal Pradesh, India. It morphologically resembles C. reniforme, but differs from it by several characters of leaves, involucres, and ray laminae, as well as the style length of ray florets, etc. We additionally report C. oblanciligulatum for the first time from India, collected from Tawang, Arunachal Pradesh. It is a threatened species and until now was only known from China. An identification key to Indian species of Cremanthodium sect. Cremanthodium is provided.

Dasymaschalon buengkanicum Uearee, Damth. & Chaowasku (Annonaceae), a new species from northeastern Thailand is described and illustrated. It is morphologically most similar to D. lomentaceum, but differs from it by having sparser indumentum on young twigs, thicker and wider leaf blade, longer flowering pedicel and petals, dissimilar colour of petals at maturity, and smaller monocarp constrictions to monocarp width ratio.

Amanita saproalba A. Kumar & Y.P. Sharma sp. nova (Amanitaceae) is described from Jammu and Kashmir, India, based on molecular (nrLSU) and morphological evidence. It belongs to Amanita subg. Lepidella sect. Lepidella stirps Vittadinii, and is closely related to A. orientisororia from China, from which it differs by its appendiculate pileus margins, larger basidiomata, small to moderately coarse, subfibrillose pyramidal warts on the pileus, and a stipe covered with coaxially arranged, recurved squamules that bruise brownish. An identification key to the species of A. sect. Lepidella known from India is provided.

Persicaria tirathgarhensis K.C. Mohan (Polygonaceae) is described and illustrated as a new species from Bastar District, Chhattisgarh State, India. It morphologically resembles P. chinensis, but differs from it by having a wingless petiole, ciliate ochreae, smaller heads, short pedicel, short perianth lobes, fewer stamens and two styles, and small, biconvex achenes.

There are seven varieties of Musa balbisiana (Musaceae) in the South and Southeast Asia. Here, Musa balbisiana var. bhutanensis P. Gyeltshen, is described and illustrated as a new variety from central Bhutan. It resembles M. balbisiana var. balbisiana and var. elavazhai, but differs from them by having a longer peduncle, oblong to broadly ovate bracts, a creamy anther with pink tinge, and shorter and more numerous seeds per fruit. The conservation status of the new variety is assessed as Data Deficient (DD).

Lysimachia brevicaulis Y.H. Tan & D.L. Quan (Primulaceae) is described and illustrated as a new species from a limestone karst in Oudomxay Province, Laos. It is tentatively placed in the subgenus Idiophyton. The new species is morphologically close to L. verbascifolia but can be distinguished from it by its underdeveloped stem, smaller leaf blades, solitary flowers, villous calyx, abaxially reddish brown and puberulent corolla, shorter anthers and styles, and green fruits.
