Revisión del 23-10-07[editar]

Veo algunos puntos a mejorar del artículo. Parte del tema es el estilo general y parte la relativa escasez de la información suministrada. Lo pongo en espera confiando que esa información se agregue y se revea el estilo en el artículo. --CASF 17:09 23 oct 2007 (CEST)

  • Estilo: se debería hacer un esfuerzo por escribir el texto con una redacción y estilo más típica de una enciclopedia, con artículos, verbos y demás. De lo contrario, las descripciones son meras enumeraciones de sustantivos, correcto para una obra dirigida a botánicos, insuficiente para una obra más general.
  • Rangos de distribución de las variables: como antes, hay que redactarlos para que no parezca un telegrama y para pueda ser entendido por cualquiera (ejemplo: carpelos (6-)7-28(-30), podría escribirse como "presentan de 7 a 28 capelos, raramente 6 o 30" ).
  • subbasales: ?
  • en la introducción se afirman que son dos especies, hacia el final que no hay seguridad.
  • Hay enlaces externos en el texto que deberían ir como citas al pie.
  • Se usa el nombre de la familia con mayúscula o minúscula, unificar.
  • debajo de los nombres de las especies se suministran localizaciones sin aclarar si es la distribución geográfica de la especie.
  • Siendo una familia monotípica, se debería incluir toda la información del género Galbulimima, ejemplos:
    • La parte química esta profundamente estudiada: se debería aclarar qué es el GB-13. Polikétido no es una buena traducción.

Himandridine, the major alkaloid of the ester group of Galbulimima alkaloids, was shown to have the hexacyclic structure (III) by systematic characterization of the functional groups and by rational degradation to the (+)-1-lutidyl-4-methylbenz[e]indan (XLI), the racemic modification of which was synthesized. Himandridine and himbosine are the first members of a new alkaloid family. Australian Journal of Chemistry 20(5) 981 - 1019"
      • Leaf Essential Oil of Galbulimima baccata (Himantandraceae) from Queensland, Australia, The

Journal of Essential Oil Research: JEOR, Sep/Oct 2005 by Brophy, Joseph J, Goldsack, Robert J, Forster, Paul I The oil of Galbulimima baccata was analyzed by GC and GC/MS. It appears, from the composition of its leaf oils, to exist in two chemotypes that can be distinguished by complex mixtures of oxygenated sesquiterpenes. In chemotype 1, the principal sesquiterpenes present were elemol/hedycaryol (12-30%), α, β- and γ-eudesmol (0.6-3%, 0.4-3% and 0.2-3%, respectively) and spathulenol (1-3%), while in chemotype 2 the sesquiterpene component was a complex mixture of C^sub 15^H^sub 22^O, C^sub 15^H^sub 24^O and C^sub 15^H^sub 26^O components, with elemol, spathulenol and the α-, β- and γ-eudesmol mixture being not much more than trace components. These two chemotypes occurred wherever the species was found. The principal monoterpenes present in both chemotypes were α-pinene (2-15%), camphene (8-25%) and δ-3-carene (0.2-13%).

      • Psychoactive properties of Galbulimima bark. Thomas B. There are several reports that the bark of the rainforest tree Galbulimima belgraveana (F. Muell.) Sprague has been chewed for its psychoactive properties in Papua New Guinea. Twenty-eight alkaloids have been isolated from Galbulimima bark. There is no direct pharmacological evidence that any of these alkaloids are psychoactive. Two different pharmacological explanations for the reported psychoactive properties of Galbulimima bark are offered.

    • La etnobotánica del género parece un tema importante como para escribir tan poco: "The use of Galbulimima belgraveana in Papua New Guinea has been reported in several popular books on psychoactive plants (BOCK in press; EMBODEN 1972; 1979; OTT 1993; 1996; RATSCH 1998; SCHULTES & HOFMANN 1979; 1980). The bark of Galbulimima belgraveana has been chewed with the leaves of an unidentified Homalomena sp. [Araceae] by the people of the Okapa region, Eastern Highlands (BARRAU 1958). The chewing of Galbulimima belgraveana bark (agara) and Homalomena sp. leaves (ereriba) has been reported to induce visions and a dream-like state (BARRAU 1958; HAMILTON 1960). Physical effects of chewing agara and eririba include violent tremor and miosis (DE SMET 1983:296; 1985). The violent tremors last for about an hour followed by a sense of calmness, euphoria and then drowsiness (DE SMET 1983:296; 1985). " "The use of Galbulimima belgraveana in indigenous medicine has been reported in Papua New Guinea (GLICK 1963; 1967; WEBB 1960; LEWIS & ELVIN-LEWIS 1977). Among the Gimi of the Eastern Highlands of Papua New Guinea the bark of Galbulimima belgraveana, incorrectly identified as Himantandra belgraveana (GLICK 1967:45), is used in ethnomedicine to counteract malevolent power which is thought to be the cause of a variety of illnesses. When an illness is believed to be caused by sorcery, the Gimi seek the assistance of the aona bana ("man of power") who is regarded as having extraordinary natural healing abilities (GLICK 1967:45)."
    • La fisiología y morfología floral merece un párrafo aparte, con su discusión filogenética:
      • "Peter K. Endress. Institut für Systematische Botanik der Universität, Zollikerstrasse 107, CH-8008 Zürich, Switzerland. The inner staminodes (between stamens and carpels) in some relicMagnoliales (Austrobaileyaceae, Degeneriaceae, Eupomatiaceae, andHimantandraceae) are not just reduced stamens; they are very elaborate organs. InEupomatiaceae, Himantandraceae, and probablyDegeneriaceae they have their own secretory structures which do not occur on the stamens. These play an important role in floral biology. They contribute to the floral coloration pattern; they effect herkogamy by their position and by movements; they provide shelter and food tissue and food secretions (?) for pollinating beetles; they secrete odouriferous oils, mucilage (probably for pollen adherence) and water or nectar (?). For theHimantandraceae a new secretory region on the base of the inner staminode is described. These complicated inner staminodes are extreme specializations of primitive floral types. They have no counterparts in more advanced subclasses of the angiosperms"
      • Gametogenesis in Galbulimima belgraveana (Himantandraceae)Prakash, DB Foreman and SJ Griffith. The flowers of Galbulimima belgraveana (F. Muell.) Sprague are bisexual, calyptrate and protogynous. The numerous free stamens are laminar and arranged spirally on an elongated receptacle; only the middle stamens are fertile. There are four microsporangia embedded on the abaxial side of the microsporophyll. The tapetum is secretory and often double. A variety of spore tetrad types is produced. The mature pollen grains are single, monosulcate, scabrate, atectate, spheroidal and 2-celled. The carpels of a flower are initially free but later become concrescent so that a single fruit is formed. The ovules are anatropous, crassinucellar and bitegminal, and show an elongated embryo sac that conforms to the polygonum type of development. There is a massive parietal tissue in early stages of ovule development. In its embryological features, the species shows close relationships to the families Annonaceae and Degeneriaceae and, to a slightly lesser extent, the Magnoliaceae and Eupomatiaceae.
