Rangel-Ch., Vladimir Minorta-Cely, Francisco Castro-Lima, L. Niño, Gerardo A. Aymard-Corredor","doi":"10.3100/hpib.v27iss1.2022.n12","DOIUrl":"https://doi.org/10.3100/hpib.v27iss1.2022.n12","url":null,"abstract":"Abstract. Forest vegetation (flooded, semi-flooded, and non-flooded or “terra firme”) of the Cumaribo region was characterized using data from 29 plots. This sector is located in municipality at the Vichada department, and in adjacent areas of the Guainía and Guaviare departments, Colombia. In 1000 m2 plots, all individuals with a diameter (DAP) > 10 cm were measured, the basal area (m2), relative abundance (%), and relative dominance (%) were calculated. The latter values helped to estimate the “reduced” importance value index (IVI).The Sigmatist school guidelines were used to classify the forests. According to floristic composition, patterns of structure, and spatial distribution of the species, forests were grouped in class Brosimo lactescentis-Eschweileretea subglandulosae with an estimated basal area of 165.7 m2 in 10,579 individuals belonging to 685 species. In Mabeo nitidae-Mespilodaphnetalia cymbari forests (14 plots, 14000 m2 of sampled area), the basal area value of 101.9 m2 was estimated at 4770 individuals in 348 species, and the Duguetio quitarensis-Amphirrhocion longifoliae alliance covered 55.94 m2 at 1901 individuals of 192 species. The association Vitici compressae-Attaleetum butyraceae presented the highest value of dominance index (basal area/sampling area) with 1.2%. In the alliance Virolo surinamensis-Mespilodaphnion cymbari, the basal area was 21.9 m2 with 1461 individuals in 138 species. The association Aspidospermo desmanthi-Mespilodaphnetum cymbari presented a basal area of 24.4 m2 with 1408 individuals and 211 species. In Phenakospermo guyannenses-Minquartietalia guianensis forests (13 plots, 13000 m2) basal area was 63.8 m2 in 5809 individuals and 486 species. These values were provided by the alliance Attaleo maripoae-Iryantherion laevis with its five associations, where the palm association Attaleo maripae-Euterpetum precatoriae showed the highest richness value index with 6.3%. The Micropholio venulosae-Eschweileretum bracteosae forests presented the highest density index with a 0.6 number of individuals/ sampling area. The present study grouped forest vegetation into one class, two orders, 2 alliances, and 10 associations. These results represent the first proposal of a phytosociological classification of the forests located in the transition region of the Orinoquia and the Colombian Amazon. Resumen. Se utilizó la información de 29 levantamientos (parcelas) para caracterizar los bosques (inundables, semi-inundables y no inundables o de “tierra firme”) en la región de Cumaribo, departamento del Vichada, y en localidades adyacentes de los departamentos del Guainía y Guaviare, Colombia. En parcelas de 1.000 m2 se midieron todos los individuos con un diámetro a la altura del pecho (DAP) > 10 cm, y se calculó el área basal (m2), abundancia relativa (%), dominancia relativa (%), con estos valores se estimo el indice de valor de importancia “reducido” (IVI).

Guapira fundacionensis from montane forests over the “Aguardiente” sandstone formation, “La Fundación” region, Andes of Táchira State, and Guapira guasarensis from “río Guasare”, on foothills and montane forests located in eastern side of Sierra de Perijá, Zulia state, both in Venezuela, are described, illustrated, and their morphological relationships with allied species are discussed. Both species have similarities with G. opposita, however they differ by having branches, petioles and perianth densely ferrugineous tomentose, by leaf shape and texture, peduncle size, and flowers subtended by three bracteoles. In a geographical and taxonomical context, G. guianensis and G. pacurero are regarded here as diferent from G. eggersiana and G. opposita, while Guapira ayacuchae is considered a synonym of G. cuspidata, G. olfersiana of G. opposita, whereas G. davidsei is regarded as a recognizable species. An updated key to the 20 Venezuelan species of Guapira is presented, and phytogeographical information about the La “Fundación” is provided. Guapira fundacionensis and G. guasarensis are remarkable species, the first by its two stigmas and the latter for bearing five glands at the top of the ovary in an otherwise predominantly one stigma genus, without glands at the top of the ovary. Resumen. Guapira fundacionensis sobre afloramientos de areniscas de la formación Aguardiente, La Fundación, estado Táchira, Andes de Venezuela y Guapira guasarensis, de bosques del piedemonte y montanos del río Guasare, del lado este de la Sierra de Perijá, estado Zulia son descritas, ilustradas y sus relaciones morfológicas con la especie afín son discutidas. Ambas especies poseen similaridades con G. opposita, sin embargo, difieren en la pubescencia densamente ferruginosa en las ramas, pecíolos y perianto, en la forma y textura de las hojas, tamaño del pedúnculo y las flores subtendidas por 3 bractéolas. En un contexto geográfico y taxonómico, G. guianensis y G. pacurero son tratadas como especies diferentes de G. eggersiana y de G. opposita. Por otra parte, G. ayacuchae es considerada un sinónimo de G. cuspidata, G. olfersiana de G. opposita y G. davidsei es reconocida como una especie válida.
