Summary. A new species of Ichthyothere (Compositae: Heliantheae: Milleriinae), I. sasakiae, is described and illustrated from the campo rupestre da Amazônia on the Serra do Rochedo, Município de Mundo Novo, northern Mato Grosso State, Brazil.
Attempts to identify a modern collection of Chromolaena (Wood et al. 19515) proved problematic, especially when comparison of type material in K, against images of types in NY, was carried out. Examination of the type material of Eupatorium bangii Rusby (= Chromolaena bangii (Rusby) R. M. King & H. Rob.) has shown that the protologue is effectively a… (More)
A new species of Neocuatrecasia (Compositae: Eupatorieae: Gyptidinae), N. epapposa, is described and illustrated from the Provincia Ñuflo de Chávez, Departmento de Santa Cruz, eastern Bolivia. The new species is compared with the other low altitude species, N. tysonii, described from the Departmento de Beni, but differs primarily in its epappose achenes… (More)
Summary. A new, dwarf perennial species of Pectis (Compositae: Heliantheae: Pectidinae), Pectis harryi, is described and illustrated from the Departamento de Santa Cruz, eastern Bolivia. The new species adds to the increasingly recognised richness of the rock platforms and low granite shield inselbergs (lajas) of the provinces of Ñuflo de Chavez and… (More)
A new species of Sciadocephala (Compositae: Eupatorieae: Adenostemmatinae), S. gracieliae, is described and illustrated from Mato Grosso State, Brazil — the first record of the genus for the country. Distinctions of the new species are discussed and the corolla colour is confirmed as green, an unusual colour in the Eupatorieae. A synopsis and key to the six… (More)
Nassauvia falklandica (Compositae: Mutisieae: Nassauviinae), a new endemic herbaceous sub-shrub from the Falkland Islands, is described, illustrated and its conservation status assessed. N. falklandica is unique within the genus in possessing a row of pits towards the apex of the abaxial surface of its leaves; stomata and stiff white hairs are confined to… (More)
The identity of Cosmos herzogii (Compositae: Heliantheae: Coreopsidinae), from the Department of Santa Cruz, eastern Bolivia, is discussed. Field observations of critical characters of the rootstock, anther filaments and achenes, of plants identified as Cosmos herzogii, indicated that the material does not belong to Cosmos but rather to Bidens; the relevant… (More)
A new purple-flowered discoid Calea (Compositae: Heliantheae: Neurolaeninae), Calea woodii (Calea sect. Meyeria (DC.) Benth. & Hook. f.), is described and illustrated from the Serranía de Cochís and the Serranía de Santa Bárbara, Chiquitos, Department of Santa Cruz, Bolivia. The relationship of this species is discussed and a key to the purple-flowered… (More)
A new species of Ichthyothere, I. woodii (Compositae: Heliantheae: Milleriinae) is described and illustrated from the cerrados of the Department of Santa Cruz, eastern Bolivia. The distribution of Bolivian and Brazilian species is tabulated, and the large number of species in cerrado and campos rupestres vegetation commented on.
During the course of a recent research project on Adenocaulon and Eriachaenium it became apparent that some of the species names had not been typified. In this study we located and designated as much type material as possible for these two genera. We indicate holotypes or lectotypes where appropriate, including one for the type of the genus Adenocaulon.
