Krapfia weberbaueri Standl. and J. F. Macbr. is an endemic species from Peru, categorized as vulnerable, and distributed in the departments of Ancash, Huanuco, Junin and San Martin. This work reports the reproductive development of the species under controlled conditions of light and temperature (12 hours light/12 hours darkness, 12 °C during light hrs and 8 °C during dark hrs). Entire plants at reproductive stage were collected at Cordillera Blanca (Ancash), where it is found forming patches, at an elevation of 4200 to 4800 m. The species has large and showy flowers, which from anthesis to the onset of senescence remain responsive, however at a greater extent in the mature flower, stage at which the dehiscence of stamens and release of pollen grains reaches 100%. This period lasts a total of 13 days. Nectar production begins when the flower matures and continues until the total senescence of petals. The viability of the pollen grains varied from 78 to 97% and success in achene production was 38-62%. It may be noted that pollination is favored by the final position of anthers over the stigmas, nectar production, moderate presence and movement of mites and aphids, and the pendulous position of the flower. © Los autores.

Summary: A synopsis of the South American genus Aschersoniodoxa Gilg & Muschl. is presented, and the new species A. peruviana Al-Shehbaz, Eduardo Navarro & A. Cano is described and illustrated. An updated generic description of Aschersoniodoxa, a discussion of its tribal placement, and a key to its four species are given. © 2012 The Board of Trustees of the Royal Botanic Gardens, Kew.

Englerocharis blanca-leoniae is described and illustrated, and its relationship to the closely related E. peruviana is discussed. As a result, Englerocharis now includes five species, all except the latter are narrowly endemic to Peru and known from single collections. The generic limit is expanded to accommodate the new species, and a key to the five known species of the genus is presented. © President and Fellows of Harvard College, 2015.

Summary: Six new species of Brassicaceae (Brayopsis chacasensis Al-Shehbaz & A. Cano, Descurainia canoensis Al-Shehbaz, Draba canoensis Al-Shehbaz, Trinidad, Ed. Navarro & D. Rodr.-Paredes, D. punoensis Al-Shehbaz, Ed. Navarro, Trinidad & A. Cano, Neuontobotrys camanaensis Al-Shehbaz & A. Cano, and Weberbauera ayacuchoensis Al-Shehbaz, A. Cano & Trindad) are described and illustrated, and their distinguishing characters from nearest relatives are discussed. Brief notes on the diversity of these five genera in South America, especially Peru, are discussed. © 2013 The Board of Trustees of the Royal Botanic Gardens, Kew.
