Los adelfares del suroeste de la Península Ibérica

The results of the phytosociological study of chaste tree scrubby communities from rivers and streams in Huelva (Spain) are presented. A new association Oenantho crocatae-Nerietum oleandri, is described. This association corresponds to riverine scrub communities of river beds with occasional running water. It is included in the alliance Securinegion buxifoliae which belongs to Salici purpureae-Populetea nigrae, due to its floristic composition and ecology. A subassociation associated to streams and rivers influenced by the Iberian pyritic belt are distinguished with the presence of Erica andevalensis.

Studies on Iberian Peninsula ultramafic flora: a selected nickel accumulation screening

A complete list of taxa from southem Iberian Peninsula ultramafics were screened for Ni accumulation. All the studied specimens were collected by the Spanish botanist Prof. Salvador Rivas Goday and are preserved in the MAF Herbarium (Facultad de Farmacia, Universidad Complutense, Madrid). The study was carried out by a semi-quantitative chemical test. Only two species of the almost two hundred tested had a positive reaction: Alyssum serpyllifolium subsp. malacitanum Rivas Goday ex G. Lopez ( Brassicaceae ) and Saxifraga gemmulosa Boiss. ( Saxifragaceae ).
