Pombalia Vand. (Violaceae) is represented in the Cerrado by a well-supported monophyletic group of species known as the Pombalia lanata complex, characterised by some unique vegetative and reproductive features within the genus. This group includes six species – Pombalia cristalina, P. insignis, P. lanata, P. poaya, P. strigoides and P. velutina – the first two of which are new to science. Pombalia lanata shows the widest geographical distribution throughout the Central Brazilian Plateau and the Espinhaço Range in Minas Gerais state, with a disjunction in Misiones Province, Argentina. Because most species in this group are narrow endemics, we evaluated the conservation status of all taxa. An identification key for the species, descriptions, illustrations, maps of geographical distribution and nomenclatural notes are also provided.

A review of the native Iranian species of Lavandula is presented, including the first recorded occurrence of L. pubescens, new distribution records for L. coronopifolia, and a detailed description and observations of the poorly known endemic L. sublepidota. The phylogenetic relationships of several taxa, including Lavandula sublepidota and L. hasikensis from Oman, are investigated for the first time using molecular data (matK and ITS regions), and changes to the sectional classification are proposed.

Chromosome counts were obtained from six species of Costaceae from Asia. Our count of 2n = 18 for Cheilocostus speciosus confirms previous counts, and the other five counts have been made for the first time (Cheilocostus borneensis, Cheilocostus globosus, Cheilocostus sopuensis, Costus muluensis and Paracostus sp.). These chromosome counts reveal two somatic numbers, 2n = 18 and 2n = 36, of which the former is a new diploid number for the genus Paracostus. A comprehensive review of existing counts was conducted through literature and database searches. Mapping of these on a published comprehensive phylogenetic tree suggests that the diploid count of 2n = 18 is probably ancestral in the Costaceae, with repeated parallel evolution of tetraploidy and one case of octoploidy. The existence of triploid counts in several lineages harbouring polyploids suggests that diploids and tetraploids may exist in close proximity, and that crosses or meioticirregularities may lead to triploid genotypes occurring frequently.

Salvia subviolacea Y.K.Wei & Pendry, a new species from China, is described. Salvia subviolacea belongs to Salvia subg. Glutinaria (Raf.) G.X.Hu, C.L.Xiang & B.T.Drew, sect. Eurysphace E.Peter, and is distinguished from morphologically similar species by differences in its habit, leaves, inflorescences and flowers. It has a disjunct distribution in Sichuan and Xizang, and its IUCN Red List conservation assessment is Endangered. The Xizang population is under extreme threat and rapid conservation measures need to be taken.

A useful character for spotting specimens of the pantropical Rubiaceae genus Eumachia is the leaves drying green. The physiological reasons for this are unresolved. We investigated whether the phenomenon is related to the accumulation of aluminium. Samples of foliage from herbarium specimens of nine species of Eumachia (Rubiaceae), including collections from Asia-Pacific, Africa and the Americas, were analysed for elemental concentrations. For comparison, specimens of the closely related genera Psychotria and Palicourea from similar geographical regions were also analysed. Two species, Palicourea violacea (Panama) and Psychotria pallens (Brazil) were found to be aluminium hyperaccumulators (≥ 1% Al by dry weight), with a third species, Eumachia collina (from New Caledonia), falling just short of the threshold with 0.99% Al. Aluminium accumulation (≥ 0.4% Al by dry weight) occurs but is infrequent among species of Eumachia and appears lesscommon than in the close relative Palicourea. Aluminium accumulation also appears patchy in Psychotria sensu stricto. It seems unlikely that herbarium greenness in Eumachia is directly related to aluminium accumulation.
