Pinguicula rosmarieae Casper, Bussmann & T.Henning (Lentibulariaceae), a new butterwort from the Amotape-Huancabamba Zone (northern Peru)

The insectivorous genus Pinguicula occurs along the whole Andean mountain chain from Colombia-Venezuela in the north to Tierra del Fuego in the south with a short interruption in the Peruvian-Chilean desert range. This paper describes a new and striking species of Pinguicula that occurs in the south-eastern part of the Amotape-Huancabamba Zone in north Peru. It grows either as a lithophyte on moist rocks or as an epiphyte on Polylepis multijuga Pilg. in the wet highlands of the Cordillera Central. Pinguicula rosmarieae Casper, Bussmann & T.Henning, sp. nov. is clearly distinguished by a basal rosette of ovate-obovate leaves spread out flat on the ground and especially by a two-partite corolla with a straight uniform tube-spur complex, two features unknown from other Andean Pinguicula species. The morphological similarity to P. calyptrata Kunth is discussed and the habitat and distribution of P. rosmarieae are characterised.

A new species of Ombrophytum (Balanophoraceae) from Chile, with notes on subterranean organs and vegetative reproduction in the family

The Chilean desert specimens of Ombrophytum (Balanophoraceae) reported in the literature as O. subterraneum (Asplund) Hansen differ structurally in several respects from that species, which was described from moist tropical forest in Bolivia. Therefore the Chilean specimens are treated as a narrowly endemic, separate species, Ombrophytum chilensis Kuijt & Delprete, on the basis of the type specimen and published photographs. Discussions on morphology, distribution and conservation status are provided for this species. Critical comments on the underground organs and reproduction in Neotropical Balanophoraceae are also presented.

The geoglyphs of the north Chilean desert: an archaeological and artistic perspective

A new review of the geoglyphs of the Atacama Desert in Northern Chile has allowed the author to define a vocabulary of forms and show how these relate to particular groups of people crossing the desert from the mountains to the sea in the prehispanic period. Geometric, zoomorphic and anthropomorphic symbols mark routes, destinations and usage by particular llama caravans. The travellers were key players in society and were winning prominence in their region from AD 800.
