Acanthaceae

Abstract: Wasshausen, Dieter C., and J. R. I. Wood. Acanthaceae of Bolivia. Contributions from the United States National Herbarium, volume 49: 152 pages (including 42 figures).—Recent fieldwork in Bolivia has resulted in the recognition of 180 species in 36 genera of Acanthaceae. The purpose of this taxonomic treatment is to discuss, in alphabetical order, all the known Bolivian species of the family, and as such, this work is a ready reference for botanists, so that they may identify their collections of acanthaceous plants or use the keys for detecting further undescribed species. Except for brief discussions to indicate possible relationships of the novelties to allied species, no phylogenetic inferences within the family have been made. A full list of synonyms for the Bolivian species and those of adjoining countries has been prepared. Keys, species descriptions, and specimen distribution data is provided. When available, illustrations, ecological and conservation data have been included. Two new species of Dicliptera, D. palmariensis and D. purpurascens are described and illustrated, and Lepidagathis alverezia is a new combination. The following 26 names are lectotypified: Ancylogyne peruviana, Aphelandra albadenia, Aphelandra simplex, Arrhostoxylum haenkeanum, Beloperone denudata, Beloperone matthewsii, Beleperone nodicaulis, Chaetochlamys ciliata, Chaetochlamys macrosiphon, Chaetothylax boliviensis, Chaetothylax tocantinus, Dicliptera pohliana, Dicliptera seriacea, Dicliptera squarrosa, Geissomeria tetragona, Justicia diamantina, Justicia dubiosa, Justicia yurimaguensis, Leptostachya parviflora, Mendoncia meyeniana, Orthotactus strobilacea, Pachystachys lutea, Porphyrocoma lanceolata, Ruellia glischrocalyx, Ruellia haenkeana, and Stephanophysum ruizianum.

Abstract: The presence of cyanogenic glycosides was determined in 70 plant species from the campus of the State University of Londrina, PR, Brazil, and a further 45 plant species from the Forestry Reserve on the Doralice Farm in Ibipora, PR, Brazil. Of the vegetative species from the State University of Londrina, 7.1% showed cyanogenic glycosides: Manihot esculenta (Euphorbiaceae), Passiflora edulis (Passifloraceae), Macadamia ternifolia (Proteaceae), Prunus persica (Rosaceae) and Beloperone sp (Acanthaceae).The first four species were considered to be potentially cyanogenic in the field. From the Forestry Reserve on the Doralice Farm, the plant species with cyanogenic glycosides were: Holocalix balanseae (Caesalpinaceae), Nectranda megapotamica (Lauraceae), Trichilia casareti (Meliaceae), Trichilia elegans (Meliaceae) and Rapanea umbellata (Myrsinaceae), making 11.1% of the total species analyzed. Only Holocalix balanseae was considered to be potentially cyanogenic in the field.
