There are 26 taxa of Tillandsia (Bromeliaceae) that occur in the department of Lambayeque, Peru, of which 12 are registered for the first time, occupying different ecoregions and plant formations, from the low tillandsial to the Jalca. Dichotomous keys for the determination of subgenera, species and varieties are presented and updated data on geographical distribution, altitudinal range, uses and conservation are also provided.

Este estudio proporciona una lista comentada de las especies de Pitcairnioideae (Bromeliaceae) del departamento de Lambayeque, Perú. Se reporta un total de cinco especies, una de ellas por primera vez para la zona de estudio y dos representan endemismos norperuanos. Las ecoregiones donde se encuentran corresponden al Desierto Cálido Tropical (DCT), Bosque Seco estacional (BSe), la transición Matorral Desértico-Bosque Seco (MD-BS) y el Bosque Pluvial Montano del Noroeste (BPMN), en las tres provincias del departamento. Se discuten las razones de endemismos, amenazas y criterios de categorización de estas.

This study provides an annotated checklist of the Puya (Bromeliaceae) species registered from Lambayeque Department; Peru. A total of five species are reported, four are registered for the first time and one of them is confirmed as endemism of Lambayeque Andes. Species were from the seasonal Dry Forest (BSe), Desert Scrub-Dry Forest transition (MD-BS) and Jalca (JA) ecoregions. A key for the Puya reported species is presented and the reasons for endemisms, threats and their categorization criteria are discussed.

Floristic composition, the life forms, the importance and strategies for the conservation of a newly discovered relict forest in the north of Peru, called La Oscurana, are analyzed (El Nogal Hamlet, Bolívar District, San Miguel de Pallaques Province, Cajamarca Department; 6° 90’ S y 79° 08’ W, 2000- 2800 m). The preliminary analysis includes 85 families, 169 genera and 258 species of vascular plants, 15 families are Pteridophyta and 70 Magnoliophyta. The family with the most genera and species are the Asteraceae in the Magnoliopsida, and the Orchidaceae in the Liliopsida. The predominant life forms of the families can be divided in 6 different categories: herbs 29 (34%), shrubs 14 (16%), trees 9 (11%), lianas 9 (11%), herbs/shrubs 7 (8%) and epiphytes 5 (6%). The exceptional diversity and the local economic use are discussed. The conservation of this fragile and important ecosyste...
