Mt Parnitha is located in Sterea Ellas (Central Greece) and is the highest mountain in the vicinity of Athens. Its wild vascular flora comprises 1096 taxa belonging to 90 families, of which 122 taxa and four families are reported here for the first time. The endemic element comprises 92 Greek, 42 Balkan and 18 Italian–Balkan–Anatolian taxa. Four Greek and three Balkan endemics are new records for the mountain. The predominance of the Mediterranean element (63.6%) and the therophytes (37.6%) underlines the Mediterranean character of the mountain's flora. The endemic elements of Mt Parnitha are presented, their protection status is mentioned and the phytogeographical affinity with neighbouring mountains is examined. Three vegetation zones and 17 habitat types within them have been identified, and those facing threats are indicated. Although the mountain is a National Park, several factors influence its flora and vegetation, the most important being its proximity to Athens.

A new species of Begonia (Begoniaceae) is described from Khammouan Province in Laos. The new species, Begonia cladotricha M.Hughes, belongs in Begonia sect. Diploclinium, and is unusual amongst Asian Begonia in having basally branched hairs on all vegetative parts of the plant.

As a result of recent genetic work, four taxa previously described by the author within Orobanche are now transferred to Phelipanche Pomel (Orobanchaceae); in addition, one of them, originally described as a subspecies, is raised to specific rank.

Three new species of Agapetes (Ericaceae) from Arunachal Pradesh, India are described and illustrated with critical comments: Agapetes arunachalensis D.Banik & M.Sanjappa (Agapetes ser. Graciles subser. Parvifoliae), Agapetes dalaiensis D.Banik & M.Sanjappa (Agapetes ser. Agapetes subser. Agapetes) and Agapetes siangensis D.Banik & M.Sanjappa (Agapetes ser. Graciles subser. Longifoliae).

A synopsis of Rivea Choisy (Convolvulaceae) accounts for all names published in the genus in a concise nomenclatural review. Three species are recognized; a key is provided to identify them. Excluded species are referred to the currently accepted names and an index of numbered specimens examined will allow curators to correctly name material in herbaria.

A new species of Barleria (Acanthaceae), Barleria samhanensis Knees, A.G.Mill. & A.Patzelt, is described from southern Oman and a provisional assessment of its conservation status is provided. Further support is given for the recognition of the summit of Jabal Samhan as a distinct floristic unit.

Gentiana cachemirica is a rare plant from northern Pakistan and northwestern India. The sectional position of this species has been a matter of considerable debate. Various authors have placed Gentiana cachemirica in one of three different sections – Gentiana sect. Isomeria, Gentiana sect. Kudoa or Gentiana sect. Pneumonanthe. The present paper assesses the taxonomic affinities of this species using a detailed study of its morphology accompanied by morphological phylogenetic and cluster analyses. Characters of the seed testa, corolla morphology and growth architecture were studied for selected species from the above-mentioned sections and closely related Gentiana sect. Cruciata. Representatives of Gentiana sect. Ciminalis were used as outgroups. Our results suggest that G. cachemirica belongs to Gentiana sect. Pneumonanthe and that its affinities are closer to the Western Asiatic group of this section.

New records in the Flora of Laos are presented, along with a short history of botanical collection in the country. The records are given in two lists, one relating to the Flore du Cambodge, du Laos et du Viêtnam and the other relating to the older Flore générale de l'Indochine.

The species of Aeschynanthus Jack (Gesneriaceae) in Thailand are revised. Twenty species are recognized, a key to the species is given, all names are typified, and detailed descriptions of all species are provided. Conservation assessments are given for all species. Aeschynanthus minutifolius D.J.Middleton is newly described. Micraeschynanthus Ridl. is reduced to synonymy and a new combination is given for its only species: Aeschynanthus dischidioides (Ridl.) D.J.Middleton.

The genus Gentianella in Nepal is revised and five species are recognized: G. angustiflora Harry Sm., G. azurea (Bunge) Holub, G. glanduligera Airy Shaw, G. lowndesii Harry Sm. and G. moorcroftiana (Wall. ex G.Don) Airy Shaw. Gentianella maddenii (C.B.Clarke) Airy Shaw, usually treated as a distinct species, is placed in synonymy of G. moorcroftiana. The genus Comastoma in Nepal is revised, four species are recognized and one new combination is made: C. falcatum (Turcz. ex Kar. & Kir.) Toyok., C. pedunculatum (D.Don) Holub, C. stellariifolium (Franch.) Holub and C. urnigerum (E.Aitken & D.G.Long) E.Aitken comb. nov. The genus Gentianopsis in Nepal is revised and three species are recognized: G. contorta (Royle) Ma, G. paludosa (Hook.) Ma and G. vvedenskyi (Grossh.) Pissjauk.

Pinochia, a new neotropical genus of Apocynaceae, subfamily Apocynoideae, is segregated from Forsteronia, described and illustrated. Four new combinations and a key to the species are provided.
