چکیده

Cedrela Boliviina. Inflorescence sparsely and minutely canescent. Leaves (only the uppermost seen) 5 dm. long, the petiole 1 dm. long, slightly grooved upon the upper surface, like the rachis, the leaflets sub-opposite, 7 to 9 pair, the internodes about a third as long as their leaflets. Petiolules very slender, about 6 mm. long, articulating by a thin, disk-like base. Blades 8 to 16 cm. long, 2.5 to 4 cm. broad, the lower successively smaller, lanceolate, with mostly obtuse or sub-rotund base and long-acuminate summit, entire, thin, the slender venation lightly prominent beneath, the secondaries 15 to 20 on each side, abruptly dilated at the base, widely spreading, lightly curved and uniting to form a thin, brown revolute margin, the remaining venation very finely reticulate and faintly impressed on both sides. Panicle (much broken in my specimen) apparently as long as the leaves, distantly branched and very loose and open, the branches elongated, divariacate or the lower declined, pedunculate and loosely flowered, the flowers shortly and stoutly pedicelled,the bractlets broadly ovate, acuminate or attenuate, longer than the young buds. Calyx campanulate, 2 mm. broad and nearly as long, lobed nearly to the base, the lobes rounded. Corolla pilose, twice the length of the calyx, the upper petals very thick. Disk 5-lobed. Filaments very slender, short, the anthers oval, nearly as broad as long, compressed. Style stout, the stigma discoid and peltate, very large. Staminodia not apparent.

Herbivore Preference for Native vs. Exotic Plants: Generalist Herbivores from Multiple Continents Prefer Exotic Plants That Are Evolutionarily Naïve

Enemy release and biotic resistance are competing, but not mutually exclusive, hypotheses addressing the success or failure of non-native plants entering a new region. Enemy release predicts that exotic plants become invasive by escaping their co-adapted herbivores and by being unrecognized or unpalatable to native herbivores that have not been selected to consume them. In contrast, biotic resi...

Income Convergence toward USA: New Evidences for Latin and South American Countries

Abstract In this paper we test two versions of convergence hypothesis namely deterministic or conditional convergence and stochastic or catching up hypothesis using Carrion-i-Silvestre et al. (2005) stationary test. The results show Latin and South American countries (LSA) catching up process toward the USA failed in 1980s and somewhat in 1990s. But in 2000s most of them could lie in converge...

A Southward Invasion.

South America and tropical Asia have the most diverse plant life on earth, so it seems intuitive that these regions would supply much of the world’s invasive species. But that’s not the case, according to a new analysis of global plant databases led by Mark van Kleunen of the University of Konstanz in Germany. The data show more nonnative plants originating from temperate Asia and Europe than a...

The invasive ‘mothcatcher’ (Araujia sericifera Brot.; Asclepiadoideae) co-opts native honeybees as its primary pollinator in South Africa

BACKGROUND AND AIMS Successful invasive plants such as Araujia sericifera usually either are capable of automatic self-pollination or maintain pollinator services by having generalized pollination systems to make use of local pollinators in the invaded range. Alternatively, plants must co-opt new pollinators with similar morphology to native pollinators or reproduce asexually. We aimed to docum...
