Chromosome numbers were determined from microsporocytes (meiotic counts) and root-tip cells (mitotic counts) in 201 collections of 51 genera and 119 specific and infraspecific taxa belonging to nine tribes of Asteraceae and Acicarpha spathulata R. Br. of Calyceraceae from Australia, Bolivia, Brazil, Chile, Mexico, and the United States. These include the first reports and new numbers for the basal members of the Barnadesieae and Mutisieae. First reports are provided for 45 taxa, including five genera, Dasyphyllum HBK (2n 5 54), Dithyrostegia A. Gray (2n 5 14), Epitriche Turcz. (2n 5 10), Revealia R. M. King & H. Rob. (2n 5 22), and Stifftia J. C. Mikan (2n 5 54). In addition, new chromosome numbers are established at the generic level in the genera Barnadesia Mutis (2n 5 54), Eremanthus Less. (2n 5 34, 30), Macvaughiella R. M. King & H. Rob. (2n 5 24), and Trichocline Cass. (2n 5 38), and in 12 additional species. Remaining counts augment and agree with previously reported determinations. The base chromosome numbers of Calyceraceae and Asteraceae are discussed in published records and our original counts.

Characteristics and hybridization of important intermountain shrubs. III, Sunflower family

Shrubs of the sunflower family are among the most common and important plants of the Intermountain area. In many valley, foothill, and mountain locations, composite shrubs, especially the sagebrushes and rabbitbrushes, provide the principal vegetation. These shrubs are invaluable as ground cover on natural and disturbed landscapes, as forage for wild and domestic herbivores, and as habitat for smaller creatures. The authors discuss and review vegetative, floral, and reproductive characteristics, hybridization, distribution and habitat, use, and division into subspecies entries for important Intermountain species. The following genera are covered:

Cytological investigation of twenty‐five weedy species belonging to twenty‐three genera were investigated for the first time from Jos Plateau, Nigeria. The chromosome numbers of three taxa; Aspilia kotchyi, Coreopsis asperaia and Lactuca capensis are reported here for the first time, while chromosome numbers of five taxa; Acanthospermum australe, Ageratum conyzoides, Ethulia conyzoides, Galinsoga parviflora and Sclerocarpus africanus differ from their previous chromosome reports.
