    Species of the Annonaceae family are used all over the tropics in traditional medicine in tropical regions for the treatment of malaria and other illnesses. Phytochemical studies of this family have revealed chemical components which could offer new alternatives for the treatment and control of malaria. Searches in scientific reference sites (SciFinder Scholar, Scielo, PubMed, ScienceDirect and ISI Web of Science) and a bibliographic literature search for species of Annonaceae used traditionally to treat malaria and fever were carried out. This family contains 2,100 species in 123 genera. We encountered 113 articles reporting medicinal use of one or more species of this family including 63 species in 27 genera with uses as antimalarials and febrifuges. Even though the same species of Annonaceae are used by diverse ethnic groups, different plant parts are often chosen for applications, and diverse methods of preparation and treatment are used. The ethanol extracts of Polyalthia debilis and Xylopia aromatica proved to be quite active against Plasmodium falciparum in vitro (median inhibition concentration, IC50 <1.5 mu g/mL). Intraperitoneal injection of Annickia chlorantha aqueous extracts (cited as Enantia chlorantha) cleared chloroquine-resistant Plasmodium yoelii nigeriensis from the blood of mice in a dose-dependant manner. More phytochemical profiles of Annonaceous species are required; especially information on the more commonly distributed antimalarial compounds in this family.
    A decade of uncertainty: Resolving the phyologenetic position of Diclinanona (Annonaceae), inlcuding taxonomic notes and a key to the species

    The molecular phylogenetic placement of Diclinanona (Annonaceae) has been debated in the literature for a decade. On the basis of morphological studies the genus was thought to be related to genera now all placed in subfam. Annonoideae. This early hypothesis was supported by the first phylogenetic analyses of Annonaceae. However, more recently a placement in subfam. Malmeoideae was hypothesised based on an analysis of more plastid data, thus contradicting older but also new morphological findings and previous phylogenetic work. The current study uses newly sequenced plastid data for two species of Diclinanona to show that the earlier hypothesised placement was correct and discusses the (little) anatomical and morphological data on Diclinanona that is available in a phylogenetic framework. Furthermore, an online revision of the three species of Diclinanona is presented in order to update the taxonomic knowledge of this genus.
    Taxonomic revision of Myrosma (Marantaceae)
    Vieira, S. ; Maas, P.J.M. ; Borchsenius, F. - \ 2012
    Blumea 57 (2012)2. - ISSN 0006-5196 - p. 125 - 130.
    central-american marantaceae - classification - phylogeny
    Myrosma is a genus of rosulate herbs characterized by a compact and strongly monosymmetric inflorescence with conspicuous, white to pale green, mostly membranous bracts, in the axil of which is a single flower pair. The genus is widely distributed throughout Central Brazil, northern South America, and the Caribbean region. It occurs mostly in savannah environments but can also be found in humid and shaded habitats. We present a taxonomic revision of Myrosma recognizing a single species, Myrosma cannifolia L.f. A complete description of that species is provided with notes on its ecology, distribution, and variation. Three species and one variety are reduced into synonymy and four names are lectotypified. A complete nomenclatural account for all combinations including the name Myrosma is given.
    Tetrameranthus (Annonaceae) revisited including a new species
    Westra, L.I.T. ; Maas, P.J.M. - \ 2012
    Phytokeys 12 (2012). - ISSN 1314-2011 - p. 1 - 21.
    The taxonomic revision of the infrequently collected genus Tetrameranthus by Westra (1985) is updated. A new species is described from French Guiana and Amapá, Brazil, increasing the number of species in this genus to seven.

    Taxonomic and nomenclatural notes on Guatteria australis (Annonaceae)
    Lobao, A.Q. ; Mello-Silva, R. de; Maas, P.J.M. ; Forzza, R.C. - \ 2011
    Phytotaxa 20 (2011). - ISSN 1179-3155 - p. 33 - 46.
    genus
    Guatteria is the largest genus of Annonaceae, comprising ca. 300 species. The genus presents taxonomic problems, and the number of species has been overestimated. Taxonomic revision, description, comments and illustration of G. australis are presented here. As a result, 41 names have been placed in synonymy under G. australis, and three lectotypes are newly designated.
    A taxonomic survey of Guatteria section Mecocarpus including the genera Guatteriopsis and Guatteriella p.p. (Annonaceae).
    Maas, P.J.M. ; Westra, L.I.T. - \ 2011

    french-guiana - america - guyana - trees - genus
    This paper deals with a group of species of the Neotropical genus Guatteria (Annonaceae) which are characterized by leaves with tiny warts (verruculae) on both surfaces and by elongate and short-stipitate monocarps (i.e., the length of the monocarp body surpassing the length of the stipe). These species were placed by Fries in Guatteria sect. Mecocarpus (Fries 1939) (the name derives from Ancient Greek µ¿¿¿¿ = Poppy and ¿a¿p¿¿ = fruit: fruit resembling that of Papaver species). All occur in South America, none having been found elsewhere so far. Although there is much doubt nowadays about the taxonomic significance of Fries's sections, we maintain sect. Mecocarpus at present for convenience's sake. Additionally, the former genus Guatteriopsis, united with Guatteria a short time ago (Erkens & Maas 2008b), is now also included in sect. Mecocarpus. The same applies to one of the two species attributed to Guatteriella (also merged with Guatteria by Erkens & Maas 2008b), namely Guatteriella tomentosa R.E.Fr. (not Guatteria tomentosa Rusby) which is put into synonymy with Guatteria trichocarpa Erkens & Maas. One new species is described, namely Guatteria griseifolia Maas & Westra. The two species complexes of G. guianensis and G. decurrens are now treated each as a single polymorphic species. The present study falls within the framework of a planned monograph of the whole genus Guatteria.
    An updated index to genera, species, and infraspecific taxa of Neotropical Annonaceae
    Maas, P.J.M. ; Westra, L.I.T. ; Rainer, H. ; Lobao, A.Q. ; Erkens, R.H.J. - \ 2011

    Annonaceae form the most diverse family within the Magnoliales. In 1990 an Index to generic names of Annonaceae was published and in 1994 an Index to Neotropical species of Annonaceae was compiled. Especially the latter proved an immensely useful tool for Neotropical botanists. Here, we present an updated Index of all valid names in Neotropical Annonaceae on the genus and species level. It also includes nomina nuda and orthographic variants. Reference and year of first publication, synonymy, and typification are mentioned. Several new combinations are made. In addition, some lectotypifications are proposed. A supplementary list is added of all Neotropical type collections
    Costaceae
    Maas, P.J.M. ; Maas-Kamer, H. - \ 2011
    In: The plants of the Mefou proposed national park, Yanoundé, Cameroon. A conservation checklist / Cheek, M., Harvey, J.M., Onana, J.M., Kew : Kew Publishing - ISBN 9781842464007 - p. 143 - 143.
    A new species of Sipapoantha (Genianaceae: Heliae) from northern Brazil
    Lepis, K.B. ; Maas, P.J.M. ; Struwe, L. - \ 2011
    Blumea 56 (2011)1. - ISSN 0006-5196 - p. 28 - 32.
    A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.
    Erratum: The type of Canna brasiliensis (Cannaceae)
    Maas-van De Kamer, H. ; Maas, P.J.M. - \ 2010

    Synoptic revision of Stenanona (Annonaceae)
    Schatz, G.E. ; Maas, P.J.M. - \ 2010
    Blumea 55 (2010)3. - ISSN 0006-5196 - p. 205 - 223.
    Preparation of a treatment of the Annonaceae for the Flora Mesoamericana necessitates the description of five new species of Stenanona (S. carrillensis, S. hondurensis, S. monticola, S. tuberculata and S. tubiflora); three additional new species are described from Colombia (S. columbiensis and S. narinensis) and Mexico (S. wendtii). A key to the 14 recognized species in the genus is presented, as well as notes on potential relationships, distribution, and conservation status.
