(2786) Ipomoea L., Sp. Pl.: 159. 1 Mai 1753 [Convolvul.], nom. cons. Typus: I. triloba typ. prop. L. is the largest (650–900 species, depending on concept adopted) and most iconic genus in Convolvulaceae, a family of c. 1880 species (data from Staples, Convolvulaceae Unlimited, 2012 at: http//convolvulaceae.myspecies.info), including important crop sweetpotato, batatas (L.) Lam. (Tabl. Encycl. 1: 465. 1793), several ornamental commonly known as "bindweeds" or "morning glories" (Wilkin Kew...
Abstract— Ternstroemia is a genus with ca. 141 species, of which 87‐103 are present in the Neotropics. As part studies Colombia, here we propose four new species: pacifica (from Chocó), T. fandango (Caribe-Cordillera Central transition), cachalu , and religiosa (both from Cordillera Oriental). show morphological affinities Amazonian Andean no clear affinities. Since some species have been either excluded or included for country literature, clarify how many occur Colombia. From total 21...
Ternstroemia es un género con ca. 141 especies de los trópicos húmedos del mundo, una especie que alcanza Corea y Japón. Una conjunción ecosistemas higrófilos sistemas montaña alta diversidad e historias geológicas complementarias, convierte a Venezuela en el país mayor número nivel global, incluyendo densidad taxones (ca. 2,8 × 10-5spp./km2) elevado grado endemismo (32%). Se reconocen 28 especies, ellas descrita aquí (Ternstroemia igapicola sp. nov.), se proponen seis sinónimos nuevos...
In Venezuela, Roystonea oleracea commonly forms communities in flooded and swampy areas on fertile soils mainly the northern portion of Orinoco river basin. The density R. varies across its range from dominating canopy to being rare. Communities dominated by are distributed country east (Sucre Monagas States) south-west (Barinas State). western-central region community is present along Tocuyo, Yaracuy Aroa basins. all most cases, found with other palms such as Bactris major var. major, trees...
In this paper we describe and illustrate Caraipa pilosa, a new species from the Venezuelan Guayana endemic to Parú massif, morphologically similar C. aracaensis, Serra do Aracá in Amazonas, Brazil. These two have leaf type (conspicuously coriaceous, margins revolute with conspicuous pubescence on abaxial surface), but pilosa trichomes are longer (≤1 mm) than aracaensis (≤0.1 present young stems, upper surface (especially leaves), inflorescence axes, sepals, ovaries, fruits. Also, Carapia...
Parodiolyra aratitiyopensis J. R. Grande (Poaceae, Bambusoideae, Olyreae, Olyrineae) is described and illustrated with material from Cerro Aratitiyope, in the southern part of Amazonas, Venezuela. This new taxon can be distinguished P. luetzelburgii (Pilg.) Soderstr. & Zuloaga, most similar species, by its smaller habit, linear-lanceolate leaf blades a rounded or truncate base scabrous margins (vs. fimbriate margins), inflorescences that are only at nodes, female spikelets hairs to 1 mm long...
Digitaria radicosa is reported for the first time from New World. The voucher specimens are lawn gardens and sidewalks in Caracas, capital city of Venezuela, can be identified by its essentially smooth rachis margin. Additionally, velutina new Venezuelan flora. came disturbed sites Andes Coastal Cordillera, above 1500 m elevation. recognized inflorescence ramification, clearly branched lowest racemes, also having smallest spikelets among species section Digitaria. A key provided section.
Abstract A proposal to change the conserved type of Ipomoea was published in December 2020, and recommended by Nomenclature Committee 2023. This done light possible negative consequences for a name crop sweetpotato, which risk our would significantly minimize. Recently, Muñoz‐Rodríguez & al. have rebuttal this proposal, we respond here. The objections raised these authors focus as much on expertise credibility group merits arguments. In “rebuttal rebuttal”, scientific questions raised,...
El género Freziera Willd. se encuentra distribuido en Venezuela a lo largo de los sistemas montañosos Los Andes, la Cordillera Costa y el Escudo Guayanés. Dos las 11 especies conocidas del país son endémicas podrían encontrarse amenazadas, pero su estado real conservación desconoce, correspondiendo categoría Datos Deficientes acuerdo con criterios UICN. En presente trabajo ofrece por primera vez una clave para todas presentes describe e ilustra polita A.L.Weitzman ex J.R.Grande, sp. nov.,...

The new species Bonamia jiviorum J. R. Grande (Convolvuloideae, Cresseae) is described and illustrated from northwestern Amazonas in Venezuela. This taxon morphologically similar to B. apurensis D. F. Austin. It characterized by its relatively small, ovate-orbicular leaves that are densely rough-tomentulose over both surfaces have a truncate subcordate base rounded obtuse, mucronulate or minutely retuse apex; lax, aphyllous infructescences with short peduncles short, adpressed bracts;...
Ternstroemia killipiana, a species endemic to Cordillera Oriental of Colombia, was collected by Ellsworth P. Killip in 1926, and described Clarence E. Kobuski 1942. Since this date, taxon it had not been recollected until the new collection reported here. A full description based on recent from "Serranía de Las Quinchas" (middle Magdalena river), Boyacá department, which for first time includes detailed information calyx corolla, an illustration, updated key 15 Colombia are provided. The...
Como adelanto de la revisión del género Ternstroemia para el área Escudo Guayanés, en norte Sudamérica, T. tepuiensis J.R.Grande, sp. nov. es descrita como especie nueva ciencia. Esta especie, caracterizada por presentar hojas, flores y frutos relativamente grandes, los con dehiscencia circuncisa, solo se conoce las montañas tabulares arenisca comúnmente llamadas «tepuyes», donde parece ser un elemento florístico bastante común. Se incluye información morfoanatómica notas sobre su ecología...
A new species of Heteranthera (Pontederiaceae), H. yucatana, is described, discussed, and iconographically documented based on material from Yucatan state, Mexico. The known a few small ponds along narrow strip dry forests shrublands over limestone outcrops derived soils the northwestern edge Peninsula. related has been hitherto confused with seubertiana eastern Brazil but easily distinguishable by its substantially smaller habit flowers. Furthermore, perianth lobes are lilac white-greenish...
