Deprea sapalachense (Solanaceae), a new species from northern Peru, is described and illustrated in detail. Deprea sapalachense S. Leiva & Barboza is found in Chorro Blanco, Sapalache-El Carmen de la Frontera road km 6, 5°07'29.9" S 79°22'53.0" W, 2740 m of elevation. It can be recognized because it has 2 (-3) flowers per node, corolla tube developed and glabrous internally, staminal filaments homodynamous, berry conical, orange when mature, 10-11 mm long and 11-12 mm of diameter, fructiferous calyx appressed wrapping tightly the berry in all its lenght, (31-) 50-67 seeds per berry, 20-22 sclerosomes per berry, shrubs 1-1.40 m tall. We include data of its relation with other similar species, geographic distribution, ecology, phenology, current status, common name and uses of the species. [ABSTRACT FROM AUTHOR]

Deprea micrantha (Solanaceae), a new species from Ecuador, is described and illustrated in detail. Deprea micrantha Barboza & S. Leiva is found in San Francisco Biological Reserve, km 274½ between El Tambo and Sabanilla (Zamora-Loja route), province of Zamora Chinchipe, Ecuador, between 1874-1922 m of elevation.

Deprea auccana S. Leiva, Barboza & Deanna and D. physalidicalyx Leiva, Barboza & Deanna (Solanaceae) are described and illustrated. Deprea auccana inhabits Abra Patricia Private Reserve (ECOAN, Pomacochas-Nueva Cajamarca road, District Yambrasbamba, Prov. Bongará, Dept. Amazonas, Peru). This species is distinguished by the shape and size of its leaves, number of flowers per node, length of calyx lobes, homodynamous stamens, and its erect fruits with a fruiting accrescent calyx bipartite when mature. Deprea physalidicalyx S. Leiva, Barboza & Deanna inhabits in the Aguashiyacu waterfall (Tarapoto-Juanjuí road, Prov. Tarapoto, Dept. San Martín, Peru) and it is characterized by the corolla lobes deep purple on the middle and cream on the margins internally, homodynamous stamens, and the creamy berry when mature loosely enveloped by a fruiting calyx very accrescent and inflated, 3.5-4 cm long, 2.3-2.7 cm diameter. Data about geographic distribution, ecology, phenology, conservation assessment and differences with related species are included. [ABSTRACT FROM AUTHOR]

Salpichroa weigendii (Solanaceae), a new species from Huanuco Region, Peru, is described and illustrated in detail. S. weigendii S. Leiva, Jara & Barboza is characterized by having glabrous corolla externally and internally, corolla limb reflex, androecium included, staminal filaments flattened, glabrous, anthers whitish, nectariferous disc red, berries intense purple or black when mature, seeds black, 16-20 per berry, fructiferous calyx covers almost the quarter basal of the berry, style 9-9.5 mm long, shrub 2-2.5 m of length. In addition to the description, we present the respective illustration, we discuss its relations with an allied species and we include data about ethnobotany, geographic distribution, ecology, phenology, current status and uses of the species.

Leiva is characterized by having calyx and corolla densely pubescent outside with simple and bifurcate non-glandular trichomes, corolla tube glabrous within, androecium and gynoecium included, staminal filaments slightly broadened at the apex, style and ovary with short trichomes, and berries intensely purple or black when mature. In addition to the description, we present the respective illustration, we discuss its relationships with allied species and we include data about geographic distribution, ecology, phenology, current status and uses of the species.

The flora and the vegetation of basaltic outcrops were studied in central Argentina. Coverabundance scores were recorded for 303 plant species in 48 relevés distributed in four outcrop locations ranging between 400 to 900 m asl. The association between the floristic composition and climatic variables were explored through an ordination analysis, and the vegetation of the outcrops was classified into four major types through a classification technique. The floristic composition of the outcrops was significantly associated to climate at the regional scale and the four sites differed in species richness, diversity and dominance. We conclude that well conserved basaltic outcrops from central Argentina are relevant habitats for the conservation of endemic species and over exploited taxa. [ABSTRACT FROM AUTHOR]
