The new species Carpolobia gabonica Breteler (Polygalaceae) from Gabon and adjacent Congo is described and illustrated. It is most closely related to Carpolobia gossweileri (Exell) E.M.A.Petit. The differences between the two species are summarised in a key which also includes Carpolobia alba G.Don, the only other species from that area.

A synopsis of the native and naturalised species of Senna (Leguminosae: Caesalpinioideae) in the Arabian Peninsula is provided. Nine species are recognised. A key to the species is presented. For each species the accepted name with selected synonymy is given, followed by a diagnostic morphological description, the geographical distribution, details of habitat preference, and citation of specimens studied. Preliminary regional conservation assessments are given for all species.

Asian and Pacific species of Manilkara (Sapotaceae) are revised. Thirteen species are recognised and a key is given. All names are typified and detailed descriptions with distribution maps and conservation assessments are provided.

Two new species, Saussurea bhutkesh and S. kanaii, belonging to subgenus Eriocoryne (DC.) Hook.f., are described from the Nepal Himalaya. S. bhutkesh differs from S. nishiokae Kitam. in having uniseriate scattered phyllaries and golden yellow hairs on the leaves. S. kanaii differs from S. topkegolensis H. Ohba & S. Akiyama in having conspicuously laciniate leaves with dense white tomentose hairs on the abaxial surface. A key is provided to the Nepalese species of the subgenus.

The genus Caulokaempferia (Zingiberaceae) is recorded for the first time from Laos with the description and illustration of the new species C. burttii.

Two new names and one new combination are created in the artificial Cynoglossum montanum group (Boraginaceae – Cynoglosseae): Cynoglossum natolicum (Bornm.) Sutorý and Cynoglossum brandii Sutorý from the Eastern Mediterranean, and Cynoglossum maghrebicum Sutorý from Morocco and Algeria. All taxa are discussed, their lectotypes are designated and their distributions are outlined.

A new species of gentian, Gentianella griersonii E. Aitken & D.G. Long sp. nov. (Gentianaceae). endemic to Central and Northern Bhutan, is described. Its generic placement and differences from allied species are discussed.

Barbarea hedgeana Kit Tan & Gemici (Cruciferae) is illustrated and described from southwest Anatolia. It is a small perennial marked by a distinct overall fruiting facies.

A generic key to 81 genera representing 255 naturally occurring species known from Belize is presented using easily distinguished characters and including illustrations of many of the genera. An up-to-date list of the grasses of Belize is also given.

The Indian Desmos viridiflorus (Annonaceae) was first described as Unona viridiflora by Beddome, but this was a later homonym of a species from South America. The correct citation of the species is therefore Desmos viridiflorus Saff. (1912). Unona viridiflora Bedd. is lectotypified.

When, in 1989, I wrote an account of Santalaceae for Flora Zambesiaca (which account will not be published for several more years), I had no hesitation in including Colpoon Berg, in Osyris L., as A. De Candolle (1857) had originally done. The morphology of stem and leaf is identical: distinctive flattened twigs, branchlets ribbed by vascular strands running out into the midrib of the leaf, and both leaf surfaces closely and minutely white-dotted (these dots are probably the ‘abundant cluster and sphaerocrystals noted in the mesophyll of Osyris abyssinica’ by Metcalfe & Chalk (1950, p. 1197)).

A new species, Colchicum chlorobasis (Colchicaceae), endemic to S Turkey, is described. The species is related to C. boissieri but differs mainly in having a larger, more rounded corm with only short lobes, browner more evanescent tunics projecting along the cataphyll, and more leaves. Both have greenish filament bases. Comparisons are also made with C. sieheanum and C. baytopiorum. A key and illustrations are provided to distinguish these four species, and their distribution is shown on a map. Chromosome numbers have been determined for C. chlorobasis, C. boissieri and C. baytopiorum.

Bulbophyllum nepalense Raskoti & Ale (Orchidaceae) from Nepal is described and illustrated. Notes on the diagnostic characters used to distinguish it from the similar species Bulbophyllum retusiusculum are provided.
