Veraguas: Along trail to summit of Cerro Tute about 1/ 2 mile above the Escuela Agrícola Alto Piedra near Santa Fe, 8.48222°N, - 1.09805°W, 900–1100 m, 29 January 1989, Almedaet al. 6480 (CAS, MO, NY, PMA). Illustration:— Fig. 26. Common names and documented uses:— None recorded. Habitat, distribution and ecology:— A local and uncommon species known only from cloud forests of Cerro Tute in the province of Veraguas, Panama (Fig. 16), at 860–1300 m. Phenology:— Collected in fruit in January and February. Etymology:— The specific epithet refers to the province of Veraguas in Panama, where this species appears to be endemic. Discussion:— This species has a distinctive white-translucent lanate vegetative indumentum, flowers that are congested in fasciculate glomerules with conspicuous bracts, and large bright orange mature berries. In its poorly developed inflorescences and rugose seeds, M. veraguensis is most similar, and also most closely related, to those species in the Approximata subclade that have sessile fasciculate glomerules. Miconia approximata which occurs nearly throughout Central America south to Ecuador has a thicker and darker vestiture, shorter, globose-oblate fruits at maturity (2–2.5 × 5–6 mm vs. 6.59–7.34 × 4.31–5.3 mm that is globose-elliptic to globose-obovate). In Veraguas province, M. approximata is only known from Isla de Coiba. Miconia veraguensis is also similar to M. chocoensis and M. quadridomius, two South American species that have a longer lanate indumentum (1.5–3 mm vs. 1–1.5 mm) and smaller berries. Although flowers of this species remain unknown, it is clearly distinct from its close relatives in the characters mentioned above. Conservation status:— This species would be considered Critically endangered CR Dbased on IUCN criteria. Because this species is rare and local in a protected area of the Cerro Tute in Veraguas, Panama, a status of Vulnerable VU is warranted. 140 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 141 142 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 143 144 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 145 146 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 147 148 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 149 Excluded species Clidemia radicans Pilger (1905: 179).

    No full text
    We provide a general valuation approach for capital budgeting decisions involving the modularization of a system. Within the framework developed by Baldwin and Clark (2000), we implement an approach using a numerical procedure based on the Least Squares Monte Carlo method proposed by Longstaff and Schwartz (2001). The approach is accurate, general and flexible

    A Fast Conservative Spectral Solver For The Nonlinear Boltzmann Collision Operator

    No full text
    We present a conservative spectral method for the fully nonlinear Boltzmann collision operator based on the weighted convolution structure in Fourier space developed by Gamba and Tharkabhushnanam.. This method can simulate a broad class of collisions, including both elastic and inelastic collisions as well as angularly dependent cross sections in which grazing collisions play a major role. The extension presented in this paper consists of factorizing the convolution weight on quadrature points by exploiting the symmetric nature of the particle interaction law, which reduces the computational cost and memory requirements of the method to O(M(2)N(4)logN) from the O(N-6) complexity of the original spectral method, where N is the number of velocity grid points in each velocity dimension and M is the number of quadrature points in the factorization, which can be taken to be much smaller than N. We present preliminary numerical results.Mathematic

    A comparison of various geometrical feature for damage assessment in VHR urban imagery

    No full text
    Urban areas require scene interpretation tools with particular attention to geometric features. Indeed, spatial analysis must be coupled to spectral characterization of ur- ban materials if reliable and suitable land use or change detection maps needs to be extracted. This is particularly true for Very High spatial resolution (VHR) imagery, increasingly available both in the optical and the microwave regions of the electro- magnetic spectrum. In past work on spaceborne characterization of urban areas the most common geomet- rical clues to scene interpretation in urban areas have always been segments, or edges. They were used for instance for land use discrimination [1] or improved change detec- tion techniques [2]. More complex geometrical features have been traditionally used for aerial image interpretation, with a long experience due to the longer availability of finer spatial resolution data. In the near future the availability of VHR data from spaceborne platforms requires somehow a convergence of the two methodologies. In this work, we try and analyze the possibility to exploit higher level geometrical features, easily available in urban areas from VHR spaceborne imagery, to extract information which not only improve change detection, but somehow allows a better damage characterization than currently available. The methodology tries and exploits the same clues to image interpretation that human interpreters usually look for in an image. Examples are regular geometrical patterns (like rectangular shapes), pairs of corresponding and parallel segments, corners with sufficient similarity. All of them will be extracted and considered in the examples proposed in the final paper to improve the possibility to detect or assess change due to destructive events in urban areas. The algorithms developed in recent years by the group for geometrical scene analyysis [3] segment extraction [4] and junction detection [5] will be therefore revised and jointly applied to improve the knowledge of pre-and post-event scenes in areas affected by earthquakes, with particular stress on Quickbird data for the 2003 Bam (Iran) event.

Cotopaxi: (Cantón La Maná), Reserva Ecológica Los Illinazas, Cerro Tilipulo, vertiente N, Cordillera Tilinche, bosque primario, 0°45’46”S, 79°06’14”W, 1375 m, 24 July 2003, Silverstone-Sopkin et al. 9409 (CAS, CUVC). Illustration:— Fig. 18. Common names and documented uses:— None recorded. Habitat, distribution and ecology:— This species is known from only two collections, one at the Awá Reserve in Carchi and another from the Illinazas Ecological Reserve in Cotopaxi, Ecuador (Fig. 11). It grows in flat areas of primary premontane rainforests at 1375–1600 m. Phenology:— Collected in flower in September, and in fruit in July. Etymology:— The specific epithet refers to the prominently winged internodes. Discussion:— Miconia alatissima differs in the dense indumentum on vegetative parts and hypanthia which consist of white furrowed glands combined with resinous glands or scales. It is also distinctive in having prominently winged and quadrate cauline internodes and densely papillose petals. One collection of this new species was misidentified as M. variabilis which has a totally different indumentum and anther morphology. The combination of furrowed glands and papillose petals may indicate that this species is more closely related to those belonging either to the Quinquenervia subclade, or to the Approximata subclade. Conservation status:— Critically endangered CR D. Known only from two protected areas in Ecuador; in the Awá Ethnic Reserve and in the Illinazas Ecological Reserve. No recent collections from the type area locality seen in this study.Published as part of Gamba, Diana & Almeda, Frank, 2014, Systematics of the Octopleura Clade of Miconia (Melastomataceae: Miconieae) in Tropical America, pp. 1-174 in Phytotaxa 179 (1) on pages 40-41, DOI: 10.11646/phytotaxa.179.1.

Colón-Panamá: Trail from Alto Pacora to Cerro Brewster, 9°18'N, 79°16'W, 700 m, 18 November 1985, de Nevers et al. 6233 (CAS, MO). Illustration:— Fig. 21. Common names and documented uses:— None recorded. Habitat, distribution and ecology:— Known from the westernmost part of the province of Colón in Panama, disjunctly to Alto Pacora, and in La Virgen in Costa Rica (Fig. 14), at 60–700 m. Most of the collections are from lowland forests on steep slopes near the site of a copper mine in Panama (60–155 m), and there is one record from a higher elevation (700 m) tropical wet forest on a trail that connects Alto Pacora with Cerro Brewster. In its restricted range this species is commonly found close to streams. Phenology:— Collected in flower and fruit in July and August; with inmature flowers in August, and only in fruit in April, September and November. Etymology:— The specific epithet refers to the large widely decurrent leaf bases of this species. Discussion:— This species can be readily recognized by its widely decurrent foliar bases that extend all the way to the node, superficial glabrosity throughout, and 5-merous flowers. The Panamanian individuals have leaves that are laxly reticulate and reddish abaxially. This coloration is not present in the one Costa Rican collection. It most resembles M. laxivenula which has similar caducous squamate-amorphous indumentum and laxly reticulate leaves, but with prevailingly 4-merous flowers and leaves that are never sessile. The decurrent leaf bases and large leaves are similar to M. sessilis, which has a more obvious puberulent indumentum and 4-merous flowers. 84 Phytotaxa 179 (1) © 2014 Magnolia Press GAMBA & ALMEDA Conservation status:— This species would be considered Endangered EN B2ab(iii) based on IUCN criteria (AOO). Althought it occurs in an area that will become protected, the AOO, its fragmented habitat and its destruction result in this taxon being relegated to the threatened category of Vulnerable VU. This species is considered not endangered by the MPSA database. The MPSA is a mining concession in Panama that is currently evaluating the plant diversity around the mine areas with assistance from staff botanists at the Missouri Botanical Garden and collaborating specialists. This species was recently collected in what would become a protected area around the mine.Published as part of Gamba, Diana & Almeda, Frank, 2014, Systematics of the Octopleura Clade of Miconia (Melastomataceae: Miconieae) in Tropical America, pp. 1-174 in Phytotaxa 179 (1) on pages 83-85, DOI: 10.11646/phytotaxa.179.1.

Panamá: Along El Llano Carti-Tupile road, 12 mi above Pan-Am Hwy, 200–500 m, 26 March 1973, Liesner 1135 (CAS, NY). Illustration:— None found. Common names and documented uses:— None recorded. Habitat, distribution and ecology:— Local and uncommon in understories of rain forests, typically in deep shade and/or along streams in Panama, Colombia and Ecuador (Fig. 16), at 0–720 m. It is most common in the Bajo Calima region (part of the Chocó) in the department of Valle in Colombia. It was recently reported from Panama (Almeda 2009). Specimens from Ecuador that were previously attributed to this species are M. chocoensis. Phenology:— Collected in flower from January through March and from May through August; in fruit from February through March, June through September, and in December. Etymology:— The specific epithet honors José Cuatrecasas (1903–1996), Spanish botanist and prolific collector of Colombian plants. Discussion:— This distinctive species has an indumentum of elongate-roughened trichomes on vegetative and hypanthial parts, conspicuous 5-plinerved leaves and a poorly developed-sessile inflorescence. Almeda (2009) SYSTEMATICS OF THE OCTOPLEURA CLADE OF MICONIA Phytotaxa 179 (1) © 2014 Magnolia Press 109 noted that the Panamanian populations differ from those in Colombia by the presence of shorter bracts to 2 mm long (vs. 6–7 mm long) calyx lobes adaxially glabrous (vs. resinous-puberulent); we agree with these observations. In all other characters, the material from both countries is similar in foliar shape, indumentum details, and staminal and seed morphology. In M. quadridomius the leaves are plinerved, but there is a space formed in between the innermost pair of secondary veins and the primary vein before the point of divergence. This space may serve to house insects. Althought some ants were found in this leaf area among different specimens from the Bajo Calima region (Colombia), the morphology of this structure is not a usual ant-domatium. It is more similar to an acarodomatium; further natural history studies are required in order to elucidate the function of this structure. This species is similar to M. chocoensis, but differs in the foliar plinervation and in lacking white furrowed glands on the leaves abaxially. In M. quadridomius the vegetative and hypanthial indumentum is ferrugineous (vs. white), and consists of prominently roughened flattened-deflexed trichomes (vs. slightly roughened). Miconia quadridomius is also similar to M. approximata, which has vegetative pubescence that is shorter (0.3–0.7 mm long vs. 2–3 mm long), and the abaxial tertiary and higher order foliar veins densely resinous-glandular (vs. furfuraceous). In the protologue, Wurdack (1981) provides a detailed enumeration of the differences between these species. Conservation status:— Endangered EN B2ab(iii). Protected only in Colombia in the Ensenada de Utría National Park (Chocó); the threats include destruction of its natural habitat and the fact that it is not protected in other parts of its range.Published as part of Gamba, Diana & Almeda, Frank, 2014, Systematics of the Octopleura Clade of Miconia (Melastomataceae: Miconieae) in Tropical America, pp. 1-174 in Phytotaxa 179 (1) on pages 108-110, DOI: 10.11646/phytotaxa.179.1.
