Water quality of the inner Puno Bay was evaluated; we established 12 stations, and were assessed monthly from December 2010 to April 2011. Physicochemical water parameters were determined with EPA and APHA standard methods. Nutrients were determined spectrophotometrically. The parameters of temperature, dissolved oxygen, pH, phosphates, nitrates and nitrites of water show that the outlet of the stabilization lagoon of Puno City (Espinar Island) is a critical area of contamination at the inner Puno Bay. Transparency values were low. The electrical conductivity of water showed high values. Alkalinity values were high (75 - 150 mg/L) and very high (> 150 mg/L), indicating a high content of carbonates and bicarbonates. Water hardness were high (121- 180 mg/L) and very high (> 180 mg/L). High levels of fecal coliform in waters near the island Espinar would be the result of wastewater discharges from the Puno city, without proper treatment.

During studies on the flora of Moquegua (Southern Peru), some interesting Arenaria populations (subgen. Dicranilla, Caryophyllaceae) were found. The morphology of the plants does not resemble any other neotropical Arenaria species. The most similar species known so far is Arenaria boliviana (from Bolivia and Peru) from which it differs in having a shorter stem length, ciliate (not glabrous) short branches; ovate rather than oblong-lanceolate leaves always covered with dense, long trichomes, never glabrous; pedicels shorter than or equal to the size of the calyx (not twice as long), sepals broadly ovate (not ovate-oblong) and with glabrous surface, as well as in the petals. Hence, a new species—A. acaulis—is here described and illustrated. © 2015 Magnolia Press.

The vegetation of the Polylepis incarum (Bitter) M. Kessler & Schmidt-LeBuhn forests was studied in the Lamparaquen annex in the province of Lampa, Puno department in 2009 and 2014. A total of 83 vascular species belonging to 35 families were determined. The lifeforms are represented by herbs, grasses, shrubs and trees, being mostly native and endemic species with some introduced. The queñoal ecosystem is represented by the new phytosociological unit Lupino chlorolepis-Polylepidetum incari with four subassociations identified. The floristic composition shows a moderate to high species richness, being the most representative families, Asteraceae, Poaceae, Caryophyllaceae, Fabaceae and Pteridaceae. The Braun-Blanquet phytosociological method was applied for the analysis of the vegetation units. The classification of communities was done by means of TWINSPAN software, DCA ordination analysis with CANOCO 4.5 software and a dendrogram based on the correlation of species for each quadrant which was performed with PC-ORD software. Further studies are still needed to have a broader view of the plant communities in other geographic areas, and evaluate how vegetation may be affected by climate change and human actions. © Los autores.

Montesinos-Tubée, D.B., Gonzáles, P., Navarro, E. 2015. Senecio canoi (Compositae), a new species of the Andes of Peru. Anales Jard. Bot. Madrid 72(2): e026. Senecio canoi, a new species of Compositae of the high Andes of Southern Peru, Puno department, is described and illustrated. Senecio canoi is a perennial species differing from others in the ser. Suffruticosi subser. Caespitosi by having tufted habit, oblong-spathulate leaves with toothed margin, glabrous, and white flowers.

Tigridia arequipensis (Iridaceae: Tigridieae) is a new species found in the province of Arequipa (department of Arequipa), South Peru. It is unique by its white to pale white (or pale lilac) flowers, outer tepals with purplish maroon and dark yellow spots and stripes, and inner tepals with pale purplish and bluish spots and stripes. Tigridia arequipensis is morphologically similar to T. raimondii and T. philippiana, it differs by having longer basal leaves, narrower and larger bracts, and outer tepals ovate and longer fruits. © 2016 Naturalis Biodiversity Center.

Three new species of the genus Senecio (Asteraceae, Senecioneae) belonging to S. ser. Suffruticosi subser. Caespitosi were discovered in the tributaries of the upper Tambo River, Moquegua Department, South Peru. Descriptions, diagnoses and discussions about their distribution, a table with the morphological similarities with other species of Senecio, a distribution map, conservation status assessments, and a key to the caespitose Peruvian species of S. subser. Caespitosi are provided. The new species are Senecio moqueguensis Montesinos, sp. nov. (Critically Endangered) which most closely resembles Senecio pucapampaensis Beltrán, Senecio sykorae Montesinos, sp. nov. (Critically Endangered) which most closely resembles Senecio gamolepis Cabrera, and Senecio tassaensis Montesinos, sp. nov. (Critically Endangered) which most closely resembles Senecio moqueguensis Montesinos. © Daniel B. Montesinos Tubée.
